Sony Xperia 5 battery life

[Vytsmb]

Hello, I have sony Xperia 5 and the battery life is awful. Was on 64 percent and and after 9 hours stand by it dropped to 47 percent. I have upgraded from Android 9 to 10 latest update and no improvement. Any ideas?

Try booting into safe mode and measure your stanby time again, as it could be

a programme in memory like TSR ( Terminate and Stay Resident) that is casing the battery drain.

I booted in safe mode, charged to full and overnight it just dropped 2 percent. Shall i try to reset to factory settings? Is there a program draining a battery?

Yes you can buddy

goto settings /battery it will tell in there which ones have been using a crazy amount of power.

You can factory fromat you phone by one of two ways:

Download Sony xperia companion, attach to the pc via USB cable and run Software repair

Or

goto settings on your phone, then system then reset options.

Now it holds ok through the night, about 4 percent drain. Thanks for the tip.

Hello @Vytsmb,

do you close all apps from time to time?

Swipe up to see the "task manager", then go navigate to the far left and close all.

That can also help with the battery drain.

Hi, yes I close all apps when not in use. Cheers. I got 5 hours Screen on time from full charge on xperia 5, that's a bit dissappointing. My 3 years old xz1 compact gets the same battery performance.

Hello @Vytsmb,

you are comparing apples to oranges.

Your old phone had a different type of screen, different size, differen processor...

Just look into your battery menu, you will see what uses most power, probably the screen.

Turn the brightness down, adaptive brightnesd off and you will also increase battery life.

I allways keep the brightness at around 30 percent, all extra services like gps, nfc, wifi, mobile data switched off when not in use. Adaptive brightness is off. And still just 5 hours on screen time. I read that phone reviewers got more than 8 hours wifi browsing out of this phone per charge and I think thank is not possible.

@IamNic 

you actually shouldn't be using the "clear all" option on a regular basis. it doesn't save you any battery, and actually can increase the battery drain when launching an app that you've cleared again.

clearing an app from the recent apps list or force stopping should only be used when an app is misbehaving, and not as a regular maintenance action.
