How to See Which Apps Are Draining Your Battery in Android 10 and 9

Contents

How you can find out which apps, processes or hardware are using your battery’s power so you can think over how to optimize your Android device to reduce the power consumption.

Battery power is one of the most important issue of any Android device. Users often try various methods to save battery for the Android device to be able to work at least until the evening. The phone and tablet users report that average Android device needs to be charged twice a day if it is used actively. For example, if you use to surf the Internet, watch videos, take photos and listen to music you may have the battery literally empty at about midday.

Of course, many people use car chargers. So this is almost a rule: if you are in a car – your Android device is always connected to a charger. Those who spend time on feet use power banks because they have no other way to charge their phones but want to stay online.

Of course there is yet another dubious solution – to use several phones. For instance, I have two phone numbers and two phones because of my job. Consequently they live longer on a single charge because I can surf the Internet, make calls and do all the other stuff on different devices. But the greatest disadvantage of this option for me is that I have to carry two phones with myself, which is so inconvenient. I don’t mention the fact that first you have to buy those two phones and pay for both of them.

So let us see how to find out what app, process or hardware uses the most battery power on your Android phone or tablet. I will show how to do this on my Google Pixel running Android 9 Pie.

General Tips to Avoid Battery Drain on Android

Go to Settings → Battery and activate Adaptive Battery feature. This will intellectual function will prevent apps that you use seldom from using battery power.
Decrease the screen brightness so it is high enough to comfortably read but not redundant.
Turn off Location, Bluetooth and even Wi-Fi when you know for 100% you don’t need it.
Activate the battery saver feature when you know in advance that next day you won’t have an opportunity to charge your Android phone.
Set up Google Photos (and similar apps if any) not to upload photos and videos over the mobile data.
Restrict the background activity of the app that drains battery severely:
Uninstall apps that are rapacious consumers of battery energy if you can live without them, use their alternatives or use web services instead.
If the battery eating app is a pre-installed bloatware, just turn it off and agree to uninstall its updates.
