1. See what's sucking the most juice. Navigate to Settings > Battery to see an organized breakdown of what's consuming your phone's battery. Applications and features will display in a descending list of battery hogs. If you see an application you barely use or a feature you never use, you'll want to uninstall the app or turn off the feature.

2. Reduce email, Twitter, and Facebook polling.
 Set your various messaging apps to "manual" for the polling or refresh frequency, just as a test, and you'll instantly extend your device's battery life by a significant amount. Once you see what a difference that makes, try re-enabling just the most important ones, and possibly reducing their polling frequency in the process.

3. Turn unnecessary hardware radios off.
 It's great that today's phones have LTE, NFC, GPS, Wi-Fi, and Bluetooth, but do you really need all five activated 24 hours per day? Android keeps location-based apps resident in the background, and the constant drain on your battery will become noticeable, fast. If your phone has a power control widget, you can use it to quickly turn on/off GPS (the largest power drain), NFC, Wi-Fi, Bluetooth, and LTE. On stock Android, swipe down to bring up the Notification bar, and then tap the icon on the top right corner.

4. Use the extra power saving mode if you have it.
 The aforementioned Galaxy S5 and HTC One (M8) both have Ultra Power Saving and Extreme Power Saving modes, respectively, that limits the phone to texting, phone calls, Web browsing, and Facebook. This can squeeze extra hours or even a day of standby time out of just a few remaining percentage points of battery.

5. Trim apps running in the background.
 From Settings > Apps, swipe to the left; you'll see a list of apps that are currently running. Tap on each one to see what they're for; you can stop any apps that you don't need running in the background all of the time.

6. Dump unnecessary home screen widgets and live wallpaper.
 Just because they're sitting on the home screen, seemingly inactive, doesn't mean they're not consuming power. This goes for widgets that poll status updates in the background, as well as ones that just sit there but look pretty and animated—not to mention animated live wallpaper. (But don't dump everything, as part of what makes Android great are the home screen customizations; just remove the ones you don't use.)

7. Turn down the brightness and turn off Automatic Brightness.
 It's probably obvious at this point, but you'll be surprised by how much this one alone helps to improve battery life.

8. Update your apps.
Applications often get updated to use less battery power, so you should make sure your apps are up to date. Even if you configured the phone for automatic updates, some apps still require that you manually install updates. Check for app updates in Google Play by hitting the menu key and going to My Apps.

9. Keep an eye on signal strength.
 If you're in an area with poor cellular coverage, the phone will work harder to latch onto a strong-enough signal. This has an adverse effect on battery life. There's not much you can do about this one, but keep in mind that this could be the culprit behind a seemingly weak battery; it's worth popping the phone into Airplane mode if you don't need data or voice calls.

10. Check the reviews.
 We conduct battery life tests on every single Android phone we review. Unsurprisingly, the results vary widely between handsets, even on the same network. When choosing a phone, make sure that real world talk time is sufficient. You can't go by what the manufacturer says; we see variances on the order of several hours of usage in both directions on a regular basis.

⬛️ How to Install a Complete Linux Distro on Android ⬛️



▫️For users who want to experience a complete desktop OS on their Android phone, especially tech-savvy people who don’t want to carry around a laptop or tablet, it’s entirely possible to install a fully-functional Linux OS on your Android phone.
You will need a rooted phone for this operation – you can search Appuals for a root guide for your device if you aren’t already rooted. Once you’re rooted though, the process is fairly simple.▫️

Requirements
BusyBox
VNC Viewer
Linux Deploy

🦠 The first thing you’ll want to do is install BusyBox – either directly from Google Play store, or the Magisk BusyBox module if you’re rooted with MagiskSU.

If you install BusyBox from the Google Play store, you just need to download the app, launch it, and hit the “Install” button from inside the app.

 🦠 If you’re rooted with MagiskSU, you need to launch Magisk Manager and go to Settings, then enable the “Enable Busybox” button, which will utilize Magisk’s built-in BusyBox for your device.
What BusyBox does is allow your Android system to use Linux commands normally not accessible to you – many root apps depend on this. With BusyBox installed, you’re now going to launch Linux Deploy on your device.

🦠 In the Linux Deploy menu, choose “Download”, and then you’ll be presented with an options menu. Here is where you’ll configure your Linux distro before it’s installed, and I’ll explain the important settings:

🦠 Distribution – Choose your Linux distro to install. There’s quite a large list, but the most user-friendly would be Ubuntu.
Distribution suite – Choose a version of the Linux distro you selected above.
Architecture – Do not change this, it is automatically selected based on your device.
Image size (MB) – The default is 512, but you should change this to a higher available number. Just don’t enter a number greater than 4095mb.
SSH Settings – You’ll need to change the default port of 22 here, but Android devices can only use ports about 1024. Most users would opt for port 2222.
Custom mounts – If you want to access your Android filesystem from within the Linux distro, go to “Mount points” and choose the ones you need. If you cannot enable the internal storage, change the default storage mount /storage/emulated/0 to /data/media/0.

🦠 You should set your username to “root” – this will give you permanent super-user access inside the Linux distro. When everything has been configured, press the Install button, and after it’s finished, you may launch the Linux distro with the Start button – but this will launch it in chroot, which is like a command-line terminal. So we need to access the GUI using the VNC Viewer tool.

🦠 Launch VNC and set the address to “localhost:5900” and enter your password. You now have a fully-functioning Linux desktop OS on your Android phone. You may want to begin installing Linux apps, which is done through the Linux terminal. Here are a few worth grabbing (use the commands in the terminal):
LibreOffice – apt-get install libreoffice
Firefox – apt-get install iceweasel
Python Idle – apt-get install idle
GIMP – apt-get install gimp
DropBox – apt-get install nautilus-dropbox
