excerpt:
|
||
|
|
If your Android device is constantly out of battery, you will probably check
|
||
|
|
the settings or some app. No, both of those lie, Android is a Linux so just
|
||
|
|
use top.

# Checking for Android battery drainer
|
||
|
|
|
||
|
|
```bash
|
||
|
|
top -b -n 1 -o %CPU,%MEM,CMDLINE -s1 -m 20
|
||
|
|
```
|
||
|
|
|
||
|
|
That is all there is to do upon having access to `adb shell` whatever way you
|
||
|
|
prefer. Look for high CPU and MEM use an observe the app ID for the truth.
|
||
|
|
|
||
|
|
For some reason the system and the battery monitor in settings won't bring that
|
||
|
|
to your attention.
|
||
|
|
|
||
|
|
Bonus points for you if the cause is some app performing CPU locking and heating
|
||
|
|
up your phone due to being unable to access a tracking domain that wishes to spy
|
||
|
|
upon you.
