Display battery usage not correct

[ngiamom]

Hi everyone! Im from Vietnam and I have just bought a Xperia XA for 2 days. I wonder why when i chose setting => Battery => Display battery usage it just displayed only the screen, wifi, camera, etc but didnt have other non-built in apps like facebook, instagram, games,... (i used it but they didnt appear). Is android display only the built-in apps? Thanks for your help.

Charge the phone 100% > use the phone and use those apps for more than few seconds > once the battery drops to 80% check again.

The battery usuage information will also display battery usuage from 3:rd party apps. But in my experience, when using most apps, the apps themselves doesn't use that much battery, it's the display and battery usuage from the display is displayed under "Screen" and not the apps battery usage.

If you were to download an app that uses a lot of CPU (for example a CPU benchmark app) or mobile data/WiFi and run that for a while and then check the battery usuage you will most likely see that app in the list

I saw a lot of android phone and they does display that. Moreover i used facebook and chrome and messenger also how can it not use much battery :o. I think my phone is getting trouble but have no idea how to solve it

An app that is just displaying information will in most cases not use that much battery. It's the display using most battery in that case.

When the app itself starts to use a lot of battery, it will show up on the list.

Here's an example from a test i just made where there are two 3:rd party apps showing in the list. "AliExpress" have been running in the background (seems like this app is really power hungry) and a benchmark app i ran that used a lot of CPU.

If you suspect it's not working in your phone you could perhaps download a benchmarking app and let that run for 15-20 minutes and then check the battery stats. Note that it might take a little while for the battery stats to update though. It will be easiest to test it when battery has been fully charged and charger just removed.

My battery usage doesnt add up to 100%, all 4 apps below is only 31%, where is the rest? If plus to the 34% remaining battery so it is up to 65%, not close to 100%? It is supposed to be close to 100% right? Is that mean my phone gets error? Please help
