[Q] How to set the phone to it's factory state? - Xperia Z Q&A, Help & Troubleshooting

Hello,
Is there a way to unroot/unmod/unflash your phone to it's factory state? Like delete all apps/settings/files like it was brand new.
I'm really dissapointed in the battery life of my Z now after months of using custom roms. Currently I'm using the Stock one and the battery life is nowhere as good as what I have tested few days after I bought my Z couple of months ago.
This is my battery stat then:

}
I can't even get near as that now. :/

Go to Settings>Backup & reset>Factory data reset
And your phone will reset like new.

Use BetterBatteryStats to see what is causing the wake locks which are hunting your battery life. Preferably rooted, since bbs works even better then.

Are you using primarily WiFi or a 3G connection?
Wifi..but I don't think that is the problem..i even have auto sync off..the phone has been in deep sleep for so long but there is no Idle in the Battery stats..not even 1%!

[Q] lollipop battery problems

Does anybody know if the .726 firmware has any issues with low battery life and overheating?? I have the update available but i didn't do it because i red that many z3 compact-lollipo users had problems with battery life. Thanks
Battery Issues
I had an issue when I installed it, battery life was terrible the first day. Something about Mobile Radio Active... I turned off Queue Background Data in Power Management and it seems to be better now. I haven't had any issues with overheating, although I might not be the best person to ask, cause I'm not really a heavy user. Just every day apps.
I installed the update immediately because I got sick of not being able to do anything with my sd card! I don't really see any other reason, so if you don't wanna risk it, don't update!
EDIT: Ignore what I said, battery is still terrible. It appears that lollipop's battery stats is just bad. There is something wasting my battery and I have no idea what

I upgraded my gf z3 to lollipop and the damn phone overheats constantly and has an insane battery drain. It usually drops to 40% by 8 or so for her on normal usage (she barely uses it) but since the update it dies before 9pm. There is something seriously wrong with this and I'll continue looking into this. Really aggravating. And the heat is unbearable.

With you on that one. This phone has to have one of the worst sleep battery drain I've seen. Seems like an unfinished product with unpolished crappy software

Agreed
I'm surprised there has been no software update with the gs7 series there were quick updates
Looks like the same bug from gs6 and gs7 are still present
Android os usage went down after I disabled wifi calling rather set it tp prefer cellular
LOL. Im a S7E user and I came here to read up on the new Note before I blew an Upgrade on Demand on it. The first thread I click on and it looks like the same battery problem still plagues it to this day. If you all are looking for a fix then I'm sure the S7 fix I posted a few months back will work. You can look throug my profile to find it. It should fix the "stay awake" issue.

I have no problem on mine, about 4% drain during 7 hr sleep. Once I disable programs I don't use I'm hoping for 2% drain, the same I'm getting on my old phone. I do manually kill programs I don't use often and I don't have any sync, auto updates etc. so that helps.

Location settings with Android OS 9 update issues?

The setting for MOBILE NETWORK only locations is missing. Anyone know if it's just buried or did they take that setting out completely? Just got the OS 9 update a week or so ago. Medium battery saving still has GPS running. Battery drain is starting to happen. US AT&T Snapdragon version here.

I believe you can access it here, well for just GPS only.

Miscommunication going on with Limey. I do NOT want my GPS on at all but I found the article above already. No way to turn off the gps where you sent me. WTF GOOGLE?! Some of us do not want high accuracy turned on all the damned time. It sucks your battery life away! I went from more like 26+ to less than 20. Think about all those people out there that don't have 4000 Mah batteries? They are going to be @SS out if luck!

Question Battery Drain Issue

Hi again,
My S21 Ultra is having some mad battery drain right now.
Overnight it would drop 10-20%.
The only thing i have changed from stock is that I have rooted it and installed Viper4Android.
Please can someone help. I am thinking of returning this handset and going over to Oneplus 9 pro or some other phone!

"I am thinking of returning this handset..."
I don't think that those two sentences can go together.
dear OP... you legit created a different phone by rooting and installing new stuff....

You can't return your phone if you rooted it. They will refuse you any return.

Amazon don't care
Well Gookill using 16%. Trash apps another 12%
The former two only run on my 10+ when needed and I'd never load the latter 3.
All these apps may be causing even more battery usage than shown by driving usage up with associated apks running because of them.
