Why does Samsung S4 drain battery so fast

Root it, and prohibit all the software that starts automatically at boot.

Have you installed quite a few of your own apps? Especially games. In fact, the Android background will still restart after being manually closed, so the more you install, the more background runs, and the more power you consume.

Try refining the app.

Go to the settings and applications, are there many applications that start running again after being closed for a period of time? Verify it.

Isn't the battery**? It shouldn't be possible to use the original one so fast, and it's about 5% at most for a night standby.

If you want to save some other points, you can turn off some of the functions that come with the S4 function, eye scrolling and the like. WiFi, GPS and the like don't need to be turned off, and the brightness can also be lowered. ·· If you want to save power,You can root,Streamline some files.,But be careful not to delete the mistake.。。。

Of course, it's okay to brush the ROM.,But it's still the old saying.,Flashing the machine is risky.,Be careful of bricks.。

Shutdown! There's only electricity left...

Nowadays, there are few smartphones that save points, and they all have to be charged once a day,。。 In addition, there are more and more mobile phone sensors now, and they will not save power. And is there something running in your background?

Please take a look at the recertification, you bring damage to others like this and bury yourself in the pit.
