stamina mode?

[xperiaz2]

Hi, i got the xperia z recently. Have noticed that at times the stamina mode doesnt work properly. When you toggle between it the battery life doesnt change. I then have to reset the phone post which it works fine. This has happened 3 times in the last 5 days.Does anyone know how to fix?

could you elaborate? do you mean that it doesn't turn on ?

[xperiaz2]

No. I mean i can switch it on & off however when i switch it on, it makes no difference to the estimated battery time left. However if i master reset the phone, then it turns back to normal which means - It does show a difference in the battery time when i switch it on & vice versa.

Well everyone is facing the same problem. Right now there isn't any permanent solution for same. Even I tried reseting my phone twice, after which stamina mode will work fine for few days and same problem will be back. Well I can't afford to loose my data( reinstalling all apps, even though I take backup) and reseting my phone everytime.

Hope Sony will solve this problem in next update. Till then bear with it.

that's odd it works for me, it changes from 2days to 4days on standby, which build number do you have?

@aky have you repaired your phone with PCC or SUS?

i havent taken my phone to repair anywhere but i plan to this saturday as on a full charge now it hardly shows a standby time of 20 hrs which is scary!

Yes even i lost my data thrice doing a master reset. However if you are facing the same issue how do you manage the battery life. It just gives me 20 hrs of standby time on a full charge.

You are lucky that it works fine for you, when i reset my phone i also have no problems for at least a day but then it switches back to the same problem

Yeah I did SUS but like I mentioned earlier, stamina mode was working fine for few days after reseting and SUS (here I tried both solution).
