4.7-Inch iPhone 8 To Feature Battery Capacity Comparable To Current 5.5-Inch iPhone 7 Plus

Written by  
Prominent KGI Securities analyst Ming-Chi Kuo is back once again with yet more iPhone 8 predictions, this time professing that Apple’s next-generation smartphone will adopt a stacked logic board setup in order to maximize the battery life provided to users.
From an aesthetic design perspective, this shouldn’t really change much, but it will potentially result in the 4.7-inch iPhone 8 having comparable (or even more) battery life to Apple’s current 5.5-inch iPhone 7 Plus flagship. This – if true – will be a huge jump from what Apple has been providing us with thus far.
The KGI Securities analyst has a particularly impressive record of predicting Apple’s future plans, both in terms of updated product design and new product releases.
If the next-generation iPhone indeed comes packed with the said stacked logic board, it will result in a device featuring OLED display and a battery capacity comparable to that of 5.5-inch iPhone 7 Plus – all packed in a form factor which is similar in physical size to the current 4.7-inch iPhone 7. As for actual capacity of battery, Kuo predicts that the 4.7-inch iPhone 8 model will ship with an L-shaped two-cell battery boasting a 2,700mAh cell:
As battery material tech isn’t likely to see major breakthroughs in the next 3-5 years, mainboard area can only be reduced via stacked SLP, which makes space for larger battery and extended usage time. Thanks to stacked SLP, we expect the OLED iPhone to have similar dimensions to a 4.7” TFT-LCD iPhone, and have comparable battery capacity (equipped with around 2,700 mAh L-shaped 2-cell battery pack) to a 5.5” TFT-LCD iPhone. The battery life of the OLED iPhone could be better than that of the 5.5” TFT-LCD model as OLED panels are more energy-efficient than their TFT-LCD counterparts.
One of the things to take into consideration here is that an OLED display is actually a lot more power-efficient, and therefore battery friendly, compared to a device with an LCD display such as all the iPhone models to date. That in itself could mean that Apple’s 4.7-inch iPhone 8, with its new internal design and logic board, could provide a battery performance that goes well above and beyond what is currently being experienced with the larger iPhone 7 Plus model. That device currently has a 2,900mAh cell integrated into it, but it could be outperformed with the new technical DNA of the next-generation iPhone.
We’re sure that more will come into the public domain about this as time progresses, but for now, as things stand, all of the speculation points to an extremely impressive iPhone 8.

WhatsApp needs no real introduction. It's now the world's most popular instant messaging service, and we love it to pieces. As a show of appreciation for WhatsApp and the joy it brings into our lives, we've decided to compile a comprehensive list of WhatsApp tips and tricks to help AndroidPIT readers get the most out of the app. Here are our answers to some of the most commonly asked questions about WhatsApp.

WhatsApp MessengerInstall on Google Play

Basic functions

How can I listen to WhatsApp messages discreetly?

Voice messages are played through the main speakers on your smartphone, and will usually allow all of your nearest and dearest to listen in as well. There is a deceptively simple solution for this issue: just hold the phone to your ear. The proximity sensor will think it is a standard phone call and will automatically switch speakers.

How do I cancel a WhatsApp voice message?

When you send a voice message via WhatsApp you need to hold the record button. As soon as you stop pressing the button the message will be sent. That said, you are still able to cancel these messages. Just slide your finger to the left of the input field and a small trash can will appear. This indicates that your message has been deleted.

How do I mark a favorite WhatsApp message?

If you are a heavy WhatsApp user you'll be writing and receiving a lot of messages. For one reason or another, you may want to have some of these messages more readily available than others. Go to the conversation and press down on the message you want to bookmark, all you need to do then is press on the star in the new menu at the top.
To access your favorite messages, go to the main window and click on the three vertical dots. Then enter the "Important Messages" tab and you will find your favorites there. 
whatsapp favori

How do I find individual contacts or messages in WhatsApp?

Do you need to find the details for one of your contacts but need to scroll through everyone else to find them? No problem! Just click on the magnifying glass and type the name of the person you are looking for. 
Searching is not limited to finding your contacts. If you have had a long conversation with a contact and you want to find a specific message, you can easily access it. Go to the conversation and click on the three vertical dots in the top menu, click on search and then just enter your key search words. 
whatsapp search

How do I send a file to a contact on WhatsApp?

Just follow the same procedure as above to find your contact, except this time you will need to press on the paperclip and choose "Document." You can then access your memory, select the file you want and then send. 

How do I send my location or a contact number via WhatsApp?

In some circumstances you may need to send your exact location or send the phone number of another contact. All you need to do is go to the chat window for your contact, and then click on the top right paperclip.In the menu select "Location" (obviously) and you will be given multiple options. Select the option which best fits where your current location is, and it will be sent to your contact. 
To send a contact, simply select "Contact" on the same menu, pick one from the contacts list and confirm with the arrow. 
whatsapp send

How can I be sure I have the latest version of WhatsApp?

As a general rule, the Play Store will notify you when your apps can be updated. Of course, you are able to check whether a new version is available by visiting the Play Store, click on "my apps" and you will be able to see if any updates are available. If you want to wait for the update to become available in the Play Store, you can always go to the APK file and install it manually. 
If you'd like to see what's new in WhatsApp, we recommend you wait for WhatsApp beta to become available. 

How do I install the latest WhatsApp APK?

First, head to Settings > Security > Unknown sources and ensure the box is checked.
The, on your smartphone browser either head to the WhatsApp website or APK Mirror and download the latest APK (APK Mirror is usually ahead of the WhatsApp website). Once the file's downloaded, open it to install the latest WhatsApp APK.

How can I participate in WhatsApp beta?

Like many apps, Facebook / WhatsApp offers its users the opportunity to test new features in a pre-release version. Once you're all signed up you can install the beta version of WhatsApp from the Play Store. 
whatsapp beta

How can I send messages with Google Now via WhatsApp?

If for whatever reason are unable to use your hands, you should know that you can go through Google Now to send messages via WhatsApp and it can be done entirely by speech interface?
Simply start it manually or say "Okay Google" (if you have it voice enabled), and then say "Send to #message #contact on WhatsApp." For example, "send Cuckoo Carole on WhatsApp." The application will then ask you to confirm, so you can either press the arrow or confirm vocally.

How do I make an audio or video call using WhatsApp?

Nothing could be easier! On the conversation window you will find in the top right the symbol of a phone next to the paperclip. Press it, and the application will ask if you want to make an audio or video call. Just select your preferred function and the call will start. 
whatsapp calls

How do I change my WhatsApp status?

Simply click on the three vertical dots in the upper right. On the menu, click "Status." All you need to do is press on the pen at the end of your current status and you edit it to your liking. Alternatively, you can also select the default statuses that are already available.

Photos and videos

How do I delete photos and videos sent via WhatsApp?

WhatsApp can be annoying sometimes because every time you send a picture or a video it is saved to your phone. For instance, if you took a photo in town today and then sent it to a friend, that photo will be stuck not only in your photo file but also in your WhatsApp conversation. 
You can delete these manually. Just go to the WhatsApp folder in your phone's internal memory to the media file and select what you want to delete, and then go to the "Sent" folder and select the items you want to delete. 

How can I disable automatic loading of multimedia files on WhatsApp?

When you receive a lot of images via WhatsApp you do not always want them to be downloaded by default. This isn't only because they are not that interesting, downloading them consumes a lot of data. Fear not, you can disable the annoying automatic download. Instead, you will then need to validate the download manually.
Go to the settings and then enter "Data Usage". You can then choose which items can be downloaded automatically with mobile data, WiFi or roaming. Simply click on the configuration that you want, for example "using mobile data", and then select your preferred options - you can ignore the ones you don't want.
If nothing needs to be downloaded automatically, simply turn off all of the available options.

Blocking and muting

How do I block someone on WhatsApp?

It's actually very simple. Open the conversation with the contact, press the "Menu" key and select "Block." If you decide its time to start talking again, you can find your list of blocked contacts in Settings > My Account > Privacy
whatsapp block

How do I block and report spam on WhatsApp?

Since WhatsApp version 2.1.23 was introduced it has been possible to block and report users if you receive messages you don't like or they are spamming you. You'll be offered this option every time, unless the contact is already in your address book. 

How do I stop someone from calling or messaging me on WhatsApp?

If you do not want to receive calls from certain contacts, you can simply block them. To do this, go to the WhatsApp Settings, select "My Account" adn then "Privacy". You will find "Blocked", and the procedure for blocking contacts will be outlined in there. In the new window click on the small icon at the top right and choose the contacts to block.
whatsapp block2

How do I know if someone has blocked me on WhatsApp?

There are four ways to suss whether someone has blocked you on WhatsApp. Each sign is largely meaningless by itself, but together they form a solid reason to believe that your friend doesn't want to be your friend.
Take note that WhatsApp has deliberately made it difficult to tell whether someone has blocked you or not, in order to maintain users' privacy. There's always an outlying chance that you're just being paranoid, even when all four of the below points apply.
Check the 'last seen' time
A contact's 'last seen' time appears in the top bar right under their name. If there's no information about when they were last online, this could be a bad sign. It doesn't necessarily mean that they've blocked you – it is possible to stop this information appearing without blocking someone. Your friend might just value their privacy, so don't go burning bridges just yet. Read on.
androidpit whatsapp last seen
Check the double check
Check marks are WhatsApp's way of compounding your obsessive streak by ensuring that you know what's going on on the other end of the line.
The first check mark means that your message has been sent. When the second one appears, your message has been received by the recipient's phone. This doesn’t mean that the person has read your message, just that it is on their phone; when those check marks turn blue, that's when they have seen the message. If you see the check marks turn blue, they haven't blocked you, and everything is fine. Take a deep breath.
If your messages never get beyond that single, sad gray tick, you might have been blocked.
There's a vague chance they still love you, though, surely? Time to keep digging.
androidpit whatsapp single tick
Do your calls go through?
Another indicator that your friend hates you is that all those desperate WhatsApp calls you make never go through.
Again, maybe their phone is broken, maybe they've changed their number, etc, etc, but if this one is true and the two signs above it are, too – well, thing's aren't looking good, are they?
Has their picture or profile changed?
If you notice that a contact hasn’t updated or changed their profile in a while, or they've had the same picture for months, this could mean that they’ve blocked you. Or that they just never update their profile. Maybe everything is fine.
Let's go a step further and check from a different account, meaning from a mutual friend’s smartphone. If you see here that your estranged friend's profile information and picture have changed, then we're sorry to break it you, but your friend has blocked you and, given how strangely you've been acting, with good reason.

How do I mute those annoying WhatsApp group chats?

We've all been here. You've somehow been dragged into a group chat that you either didn't really want to be in in the first place or just don't want to receive notifications from every couple of minutes. Rather than just leave the chat, which may offend some people, you can simply mute the chat so you stop receiving notifications from it. 
In WhatsApp, select the "Chats" tab and then tap on the group you want to mute. With the group open, tap the Options icon at the top right. Tap Mute, then select the amount of time you want to mute the group for. You can also untick the Show notifications box so that you never hear from the group again until you decide otherwise.
whatsapp group

Privacy and security

How do I lock WhatsApp?

Some conversations are not for further circulation. WhatsApp helps you along here by allowing you to use a PIN to access the app, so all you will need to do is remember your numbers. Some smartphone manufacturers will offer this feature by default, a good example here is the App Locker on OnePlus models, but if it isn't already in your device you can easily download an app that will do this for you. 
whatsapp pincode

How do I hide my "Last Seen", profile picture or current status on WhatsApp?

For one reason or another you may want to hide this information from your contacts. Go to the settings tab "My Account", "Privacy", and you can adjust everything from the next screen. With "Last seen" you can specify who can see your date of last access, with "Profile photo," this is obviously your picture with "Status" you can set who can see your personalized message.
whatsapp privacy

How do I enable the two step verification system on WhatsApp?

This is a great feature as it gives your WhatsApp an added layer of security. Go to settings, My Account > Verification in two stages . You can then choose to receive a verification email when you need to login to WhatsApp, such as when you're using another device.
whatsapp verification

How do I delete my WhatsApp account?

For anyone wanting to leave WhatsApp, it is possible to delete your account. If you do decide on this option you should know that all of your contacts, message history and other settings will be deleted completely, and you will not be able to restore this data if you end up changing your mind. 
If you are accepting of all of this and really, really want to delete WhatsApp, go to "Settings" and then enter the "My Account" tab. You will then find the "Delete my account" option. Confirm your selection by pressing the "Delete my account" tab.
whatsapp delete

What do I do if my smartphone is stolen?

Firstly, don't panic. If your device has been stolen your best option is to remove the number from your network, or at least to block the SIM card. If for whatever reason you aren't able to do any of this - again don't panic, you can deactivate your account via email. That said, this option is not effective if the thief can connect to your WhatsApp account. 
Just send an email clearly outlining your situation and a specific request to deactivate your WhatsApp account. Once you send the message, you'll have 30 days notice prior to deactivation. In other words, if you reconnect within 30 days after sending the email, the procedure will be canceled.

Here's the information your email needs to include:
  • The subject of the email should be "Lost / Stolen: Deactivate my account"
  • In the body of the email, type "Please deactivate my account. # 33 your-number"
After following these steps, please send email to If necessary, WhatsApp will contact you for more information concerning your request.


How do I get floating notifications on WhatsApp?

You can get floating notifications, or Chat Heads, by using the WhatsBubbles app. Here you will get floating notifications that are similar to those you find on Facebook Messenger. Another application you could consider using is SeeBye Chat Heads, which will also give you floating notifications but you will need root rights to use this app. 
whatsapp notification

How do I completely disable WhatsApp notifications?

Do you have that many contacts that you are receiving a notification every 30 seconds? The simple solution would be to just turn them off. To do this, all you need to do is go to "Settings" and you will find this option either in the notification options or in the application options itself. You can then disable your notifications.

How to turn off the sound on notifications WhatsApp

Getting a little tired of hearing an alert every 10 seconds? Just turn them off! Enter the "Settings" and then in the notifications menu, you can choose whether or not a noise will announce the arrival of any new messages. An alternate method is to simply press and hold on a conversation from the main window, then click the crossed-out speaker at the top right.
whatsapp notification2

How do I respond to WhatsApp messages from pop-ups?

If notifications are not enough, you can configure WhatsApp to open a window in the middle of your screen when you receive a message. You can then quickly respond directly from this window without having to open the entire application.
To enable these pop-ups, enter the "Settings", go to "Notifications" and then select "Popup notification".

Apple Watch To Get Theater Mode With watchOS 3.2

Written by  
Theater Mode is coming to Apple Watch with watchOS 3.2 firmware, Apple has confirmed. Here are the details.
Apple’s watchOS 3.2 hasn’t yet been released to developers, but the company has already shared the release notes for the software that outlines the changes and additional features it will bring to the wearable. Top of the list, and a name we have become familiar with recently, is Theater Mode.
Apple Watch Sport Black Digital Crown and Side Button
If the feature sounds familiar, it’s because it had been rumored to be on the way to iOS with the first iOS 10.3 beta, which was released today. The feature hasn’t made its debut as part of iOS 10.3 beta 1 as had previously been anticipated, but it does appear that the next Apple Watch software beta will bring the feature to prominence. So what exactly does it offer to us, the users?
If there’s one thing that’s clear, it’s that the name is certainly a good indication of what the feature does. Theater Mode allows Apple Watch wearers to tell the watch that they are in a theater, at which point, the Apple Watch’s raise to wake feature will be disabled, preventing it from waking the screen when they move around.
Those who still want to see the time will be able to tap their watch in order to wake it, and they will continue to receive taptic alerts of incoming notifications, but their watch’s screen will not light up unless asked to.
Apple has confirmed that Theater Mode was included in watchOS 3.1.3, but it was clearly not active, which suggests the release of watchOS 3.2 will be the first time users will get a look at the feature. When it will come to the iPhone is anyone’s guess at this point, or indeed if it ever will.
Rumors previously had the feature designed for iOS and the iPhone, but it would appear that the Apple Watch was always Apple’s destination for the feature. Whether that’s the end of it though, we’ll have to see. What we do know is that there is no Theater Mode in the new iOS 10.3 beta, at least not yet.

Digital assistants are going to be one of the main tech trends of 2017, just as smartwatches were the "next big thing" in 2014 and 2015. The path to ubiquity isn't always smooth. There are lots of bumps along the way that keep users from jumping on the bandwagon immediately. What challenges lie ahead for this technology? We'll explore the future of AI in this article.

What are the big technology companies doing with AI?

Digital AI assistants will be everywhere soon. Need some examples? Here you go: Google Assistant, Siri (Apple), Cortana(Microsoft), Alexa (Amazon Echo, also on Huawei smartphones in the US), Bixby (Samsung) and Viki (Nokia). HTC and Sony will also have AI assistants in their products, too. The list keeps on growing.
Google i o Home 00
Behind all of these services is one principle: machine learning. These assistants generate suggestions and recommendations based on context from all sources of information available to them. These operations are completed thanks to natural language processing capabilities, and the platforms are used as the master control center of the smarthomeAmazon Echo and Google Home, for example, can control many smarthome gadgets. And, Samsung has announced that Bixby will be compatible with third-party hardware to provide additional features.
The advertisements that showcase the products look nice. The assistant is shown as a part of family life, reminding a parent about appointments, ordering meals for the family and planning recipes. Check out the following videos which show Google and Amazon's vision for how Assistant and Alexa will fit into our everyday lives. 

Google Home

Google Assistant

Alexa: this is the vision of Amazon

This is all very practical, and so 2017 will be the year of digital assistants. These promotional videos make it look great, in theory, but in practice things are a little more complicated. Since these platforms are based on machine learning and are constantly evolving, they will never be a totally finished product, and as such will be difficult to compare and evaluate fairly. It will also present us with new challenges related to data protection.

Data protection is going to be difficult

All digital assistants have one thing in common: they're only really useful when a user goes "all in" with their personal data. This can have serious consequences.

1. Reporting and comparing will be considerably more difficult

This issue is of primary concern to those of us who write about technology for a living: how can you compare two digital assistants? The technology is ever-improving because it is based on machine learning, and each person uses it differently since it is so personalized to a user's life and environment. That makes is nearly impossible to answer the question of whether Cortana is better than Alexa, or if Google Assistant gives better recommendations than Bixby. These valid questions will be unanswerable. Without being able to provide answers to potential users, those thinking of buying these products will be left to test them on their own, and that has its own set of issues.

2. Test driving the technology? Not so fast

Of concern to users, it's going to be nearly impossible to evaluate one of these services without giving it all of your personal information just to test how well it works. You'll have to give it access to your shopping list, calendar, locations of your home and work, plus your habits and favorite entertainment choices. The value of this is that it can give more personalized recommendations and services over time if the assistant knows a lot about you. But is the convenience of a more personalized movie recommendation worth giving up all your personal privacy to a corporation?

3. Privacy and security of your commands

Data protectionists must all be on edge. Companies will gather and analyze your data, creating massive profiles of millions of people built from stockpiles of deeply personal information. Companies always say the data is kept safe. But how can we be certain of that? We can't. No system is 100 percent secure. Accounts can be compromised. You probably heard this happened to Yahoo recently.
A lot of the personal information which would be collected is already stored somewhere across many services like Google Maps, Amazon, Facebook, etc. Having an AI assistant would just centralize a lot of information about you. Companies can make a lot of money by using targeted marketing to sell you products, so their motives aren't necessarily to make your life more convenient with a personal assistant either.


The fact is this: manufacturers will be pushing digital assistants onto the market. We saw this at CES, where there were announcements featuring Amazon's Alexa everywhere.
Will users adopt this technology? Will they see the value it provides as practical for their everyday lives? Will people choose practicality over privacy? This will be an interesting debate in 2017.
What do you think of AI assistants? Are you skeptical or a supporter? Tell us your thoughts in the comments.

Google delivered a lot of exciting-sounding projects in 2016, but while some of them seemed good on paper, they didn't quite live up to the hype in real-life. Here are a few tweaks Google could make to sharpen up Google and related services over the next year.

Nail your Pixel lineup

The Pixel and Pixel XL are great Android handsets - great performance, good specs and about as pure a version of Android as you can get. Plus quick updates. 
However, the Pixel lineup hasn't been without its share of problems since launch last year. Whether that's purple lines across the viewfinder when you're taking a photo, Wi-Fi issues or problems with the handset switching off when it gets down to 25 percent remaining.
If Google's asking buyers to trust it as their hardware and software maker, it'll need to ensure that these issues (and plenty more) aren't present when the next Pixel phones launch, and ensure that the current unlucky owners get a fix for their problems as soon as possible.
AndroidPIt google pixel XL 9805

Decide what you're doing about messaging

On my Android phone, there's WhatsApp, Kik, Skype, Snapchat, Signal and Google Hangouts. Convincing me to install two more individual apps to achieve the same thing I can already do with a combination of those platforms is always going to be a difficult task, and I'm sure I'm not alone. 
Integrating some scaled-back version of Google Assistant into Allo is a step in the right direction, but it's not enough - messenger apps aren't a lot of use if your friends aren't already using them - and the awful privacy policy is enough to put many people off. 
AndroidPIT allo

Announce 'Andromeda'

Andromeda is Google's code name for the project to converge Android and Chrome OS. Unfortunately, at this stage, everything's still a rumor and we're left looking to companies like Jide with its (awesome) Remix OS (and Remix IO) as a stand-in.
Andromeda reportedly goes beyond simply allowing Android apps to run on Chromebooks (some devices already support this) and will aim to provide a truly converged OS that can run on either mobile or desktop.
With Microsoft as the only viable large OS to offer anything approaching this functionality, 2017 would be a great year for Google to get Andromeda out of the door, and would be a truly compelling differentiator between Android and iOS.

Set Google Assistant free

Google Assistant is the natural evolution of Google Now, and while it holds a whole lot of promise, it only currently delivers on that promise if you've bought a Pixel or Pixel XL handset. Sure, that could be because Google wants an exclusive feature for its own-branded phones, but that leaves an awful lot of Android owners out in the cold. 
While you can successfully side-load it onto non-Pixel devices, it can cause problems with other aspects of the handsets that just makes it not worthwhile. If you've got a Home device as well as a Pixel, you'll be a little perplexed as to what you can achieve through voice commands on each device.
You'd assume they can both do the same things, and control the same devices around your home, but they can't. It also can't do exactly the same things as Google Now, which remains on devices. This leads to confusion and needs to change.

Deliver Daydream for everyone

Google Daydream is the company's first real effort at making virtual reality a part of the core Android experience. As such, it comes built into Android 7.1 and newer, but that also means that only a handful of phones currently support it. 
The Pixel phones (surprise, surprise) are among that handful you can use in the Daydream View, but some users report that any longer than 15 minutes in Daydream causes their phone to overheat and requires them to stop using it until it's cooled down.
Heat isn't necessarily unexpected when a highly-demanding task like VR is undertaken by a phone, but either the software or soft, material hardware design is causing overheating problems in premium phones.  This needs to be sorted, and Google needs to push its partners hard to get more Daydream-capable handsets on the market.

Smartphones quickly become consumed by unnecessary apps that not only take up storage space, but can also affect your handset's performance and battery life. Well, enough is enough – it's time to clean up your smartphone. Here are five apps you should remove immediately. 
Whether it is by killing your battery life, using too much mobile data or shoving ads in your face: apps can be annoying in many ways. Sometimes we end up with too many apps on our phones, and the time arrives to tidy up. Delete these apps today and enjoy your smartphone more.

1. Apps that claim to save RAM

Apps running in the background eat up your RAM and use battery life, even if they're on standby. The idea behind apps that claim to boost your memory is to close these background apps systematically. Unfortunately, this exacerbates the problem.
AndroidPIT google play not working 1
Apps running in the background have to restart after you close them. Memory and battery life is used to restart the apps, and this constant closing and restarting of apps can make your phone unstable. So, these memory saving apps don't make any sense. Furthermore, Android manages RAM usage automatically and knows when to run an app or not, so third party apps aren't necessary.

2. Clean Master (or any cleaning app)

Cleaning apps promise to clean up your phone to boost performance. While it's true that deleted applications sometimes leave behind some cached data, it's not necessary to download a dedicated cleaner. Just go to Settings > Storage > and tap Cached data. At the Clear cached data prompt, hit OK.
Alternatively, you can clear the cache of individual apps by going to Settings > Apps > Downloaded and tapping on an app. On the next page, tap Clear Cache
Clean Master and similar apps often require a lot of battery power, and their in-app advertising has the potential to take a chunk out of your monthly data allowance. Remove such apps at your earliest convenience.

3. So-called antivirus apps are unnecessary for most

Your Android device and the Play Store can already do everything that antivirus apps can. For theft protection, Android Device Manager works securely without an additional app. And whether an app is actually hiding malware, Google checks with the Play Store automatically.
So-called Android antivirus apps are only useful if you are often downloading and installing APK files found outside the Play Store. Then, anti-malware apps can examine these apps during installation and offer warnings before you open them. However, you can't disinfect your smartphone. The best method to do this is – ironically – without an app.

4. Battery savers

Similar to RAM boosters, battery-saving apps are often a load of rubbish. These apps offer a solution to one of the most-loathed smartphone problems in the world and promise miracles. There are only a few exceptions to the truth that battery-saving apps are merely billboards disguised as useful apps.
To really increase battery life, you have to reduce energy demand from the operating system and all running services and apps. So to be effective, energy-saving apps would need to take control of running Android. But since Android doesn't can't be controlled without root privileges, apps available in the Play Store can't simply step in and take control. At best, apps can advise or warn you when you're chewing through too many Energon cubes, but that's about it. If it closes power-hungry apps, those apps will likely automatically reopen anyway. Thus, the effect is reversed and energy consumption could actually increase.

The alternative? Open your Battery settings. Find the app with the highest consumption in the list and forcing close it. Some app errors can also be resolved this way, which might have caused increased energy demand to begin with.

5. Difficult to delete manufacturer bloatware 

Many smartphones have a lot of apps pre-installed. Whether it's apps for hotel booking, games, or functionally questionable office apps: many manufacturers install their own useless apps alongside the compulsory set of apps from Google. Ideally, it's just storage space wasted, but in the worst case, they take up battery life, screen real estate and can't even be uninstalled.
It is therefore worthwhile to look through your app list and delete the pre-installed apps. The easiest way to do this is by grabbing the respective app in the app drawer and then pulling it onto the app info icon. Then you will see if the app is uninstallable or only deactivation. The latter option simply means the app is no longer launched upon restart and disappears from the app drawer, but it continues to occupy space anyway - these deactivated apps can only be completely removed after rooting your phone.
Some vendors won't let you uninstall Facebook, Twitter, or other social networks on your smartphone. This is annoying for users who don't care about social media, or those who don't need the app taking up space on their device. After all, in many cases, the mobile site is sufficient enough.
Remedy is to buy smartphones from manufacturers which allow the uninstallation of bloatware - for example, Huawei and Honor. Or buy smartphones which only come with a few third-party apps, like Google or Lenovo.

What other Android apps should I uninstall?

You should consider removing any app you don't use, seems to cause a particularly big battery drain, or consumes excessive data. You can check which apps have the largest impact on the last two things by going to your battery settings page or data usage page in your Settings menu.
There are often alternatives to power-hungry apps that you regularly use, so give one of those a try and you might grow to love it as much as the original.
