Android: How to save battery?

No, battery life issues aren’t the sole province of iPhone owners. Android users would also like to save a few hours before being able to charge their smartphone.

In response to this demand, publishers are offering apps to improve battery life on Android. But are they really effective?

The test

After testing several of them a few years ago without success, I have again downloaded and tested, in the last few weeks, more than a dozen applications. I picked from the most popular “battery savers” in the Play Store.

The most interesting in this test was to see the difference that these applications made when the smartphone shows less than 20% of remaining battery. Indeed, it is usually at this time that we begin to worry about running out of battery, and therefore wanting to stretch its autonomy to the maximum.

Conclusion: I was disappointed. And the problems are many.

Too much risk for little result

For starters, there are far too many apps. This is obviously a juicy market, which makes it difficult to select if you are looking at random.

Next, most apps require a rooted Android device or ADB (Android Debug Bridge) command entry, in order to elevate privileges and access more advanced functions. In my testing, I did not detect any suspicious behavior from the apps in question. However, escalation of privilege remains a risky practice that should not be encouraged, in addition to being technically beyond many users.

In the end, I elevated the privileges for the purposes of testing because otherwise the applications were pretty useless. And despite their promises, I saw little result. These applications have therefore modified Android’s Doze Mode and App Standby, making these integrated functions more aggressive. While there was indeed a positive impact on the battery, it also had a negative effect on performance. I’ve noticed lags, performance issues, and crashes, which I attribute to these apps pushing settings beyond acceptable.

How to extend your battery life otherwise?

If you have a device running a recent version of Android, I suggest you stick to the built-in Doze Mode and App Standby functions. They help balance battery life, performance and stability. Plus, Android’s “Battery Saver” feature, the equivalent of iPhone’s power saving mode, offers a great way to extend battery life when needed.

My advice: leave the battery management to Android.

If you want to increase the battery life of your smartphone, you can also follow Google’s advice:

  • activate battery saver mode;
  • avoid activities that require the screen to stay on for too long;
  • avoid constant Wi-Fi / cellular / GPS / hotspot / Bluetooth connections;
  • Avoid CPU intensive applications (games and cameras, for example).

Follow these few tips, get a power bank, and forget about the power savers from the Play Store. You will save time and avoid a lot of hassle.
