Optimizing the battery life of our phone is an art and no one wants to be left with a dry phone in the middle of the day and without the possibility of charging it. At Xataka Android we’ve talked at length about how to extend battery life and our best tricks. The curious thing about this discovery to considerably improve the autonomy of your Android phone is a consequence of one of the most popular manufacturers: Xiaomi. And I’ll tell you something: applying these three settings also works with other brands and you’ll notice it in the battery that’s left at the end of the day.

Xiaomi’s study. A couple of years ago, Xiaomi carried out a study on what consumes the most battery in its phones. In the top 5 are the Always On Display mode and brightness management, with 15% and 14% respectively. It is true that this analysis of the Chinese brand focuses on Xiaomi and MIUI devices, but it is worth remembering both functions can be found in practically all smartphones, so although each layer can do a different energy management, we still get a surprise when we take a look at the battery usage of our phone’s settings.

Be careful because we are talking about almost 30% for Xiaomi, a real barbarity, but I can already tell you that in general the screen takes a generous toll on the battery. In short, if you have a Xiaomi making these two simple adjustments will significantly improve the autonomy of your phone according to our experience, but in general it is a good idea to apply it if your mobile battery does not last long.

Three Settings That Can Be Your Battery’s Lifesaver

The first tweak is pretty obvious: the longer you have the phone’s screen on, the sooner the battery drains. Do I need to always have the screen on? Does it need to light up when we have a notification? Well, you might find it useful, but if you’re looking to stretch the battery, it’s better not.

Note: In my case I have applied it on a Samsung Galaxy A71 and the routes explained come from that terminal, but if you are going to use them on another mobile, it will not be difficult for you to find them by pulling the search engine.

So the first tweak would be to turn off the ‘Always On Display’ mode, which you’ll find in the phone’s settings, in the ‘Lock Screen’ section.

In my case I didn’t have the Always On Display activated as standard, but I did have the idea that the screen would light up with each new notification, something that I have disabled by going to the settings and there, following this path: ‘Notifications’ > ‘App notifications’ > ‘Lock screen notifications’ and once inside, disabling the toggle.

It seems silly, but between WhatsApps, emails, Telegrams and many other notifications, the phone’s screen lights up many times throughout the day.

The last setting is a must and is especially intended for lovers of maximum brightness, for example my parents: nowadays the automatic brightness does a good enough job of adjusting to forget about carrying the screen as if it were a torch.

We go to the settings and under ‘Display’ we make sure that the auto-brightness toggle is turned on. 14% in a full day is a joke worth taking into account.
