Do you find that your Android phone's battery doesn't last as long as it used to? Here is what you can try to save its autonomy.
I am always surprised at the battery life of my Android smartphones compared to that of my iPhone. Part of the reason is that I use them less, but I can still put my Android smartphones aside for a few days and regain a decent battery when my iPhone's battery has run out.
But Android phones are not immune to the problem of rapid battery drain. The problem, when trying to diagnose problems with Android smartphones, is not only the wide range of mobile OS versions that are used in the market but also the significant differences that can exist from manufacturer to manufacturer.
Fortunately for Android users, battery drain issues are usually fairly easy to fix. When a smartphone suffers from poor battery life, I have a four-step plan to fix it.
I suggest you wait a day between each step to make sure every issue has been resolved (unless the loss of energy is so great you can see it within hours).

1. Restart the smartphone

It's the fastest, easiest, and least destructive thing to try first. On most phones, you just need to press and hold the power button until you see the “Restart” option.
It is not only a question of remedying the low autonomy of the batteries. This fixes most of the problems found most of the time!

2. Update your apps

Your applications are not configured to update automatically? A not updating the app is a common cause of sudden and unexpected battery drain. Head over to the Google Play Store, update the apps that need it and see if that can help.

3. Android update

Alright, I know. Depending on the manufacturer, updates can either be made available regularly or be available when the hens have teeth.
But it's worth a try: go to Settings> System> Advanced and then search for either "About phone"> or "About tablet" or "System updates" or even "Wireless updates" ". You just might have a few things to do there!

4. Reset your settings!

This is the nuclear option, as it means that you will have to set up your phone again. Make sure you have a backup of your data before doing this.
Usually, you can access the reset options by going to Settings> System> Advanced> Reset options. However, some smartphones require you to press the power button and turn the volume up or down for this to happen, which you might find through trial and error (be careful, it's frustrating!) You can go through research on the Internet.
