Battery problem - new software?

[dugajama]

Hi!

I have Z1 for a week now. At first, I was really surprised with the length of it's battery life - it took me 2 days (first days of new cellphone, you know, how do they look ) to run out of juice, but after new Sony software update, fully charged battery goes to 15-20% after 10 hours of normal work mode. This COULD be understandable, but I can't really get, that during night, my phone uses up 30% of its battery (wifi off, gps off, bluetooth off, no additional applications working, stamina mode ON), when BEFORE software update it took like 2%.

What's wrong, Sony?

I am using Z1 for past 18 Days, There's no such battery problem experienced with my handset.  Try re installing the entire software package using Sony Updater, Hopefully will solve your problem. 

Download Updater from from: http://software.sonymobile.com/emma/install_packs/Update_Service_Setup-2.13.10.201308300830.exe

i am having the same problem with the battery.

Do we have to update that link you sent in the phone or the desktop ?

[MUSHARAB]

Try that link on PC. It will download 47.6MB setup that will guide you how to Re install software. The software size is around 842MB for Z1 so make sure you have a good internet connection.

I tried it, we will see how it survives the night.

It worked perfectly. Even better, than in the beginning. Cheers!

did ur data got erased while u updated ur phone?? i mean the apps dat u installed n ur msgs n contacts?

The problem came back. It's even worse than before. Here are screens of power management:

Tried to turn off WiFi and WiFi dependance to Z1 location, but it doesn't seem to work. Only thing, that I (well, it was installed without my agreement) installed in last few days, were Google Play Services.

I paid a lot of money for that phone. I shouldn't be forced to do fabric reset every two weeks. Sony, please, fix that issue.

Anyone?

In case, anyone is interested, these are my last 35 hours of NOT using my phone.

PLEASE, can somebody help me with that?
