xperia m battery drain issue

[madura]

I have an xperia m bought on last december. with my usage pattern, i was able to use the phone for three days once it is been charged. but suddenly it started to drain so fast. now i can't even use the fully charged phone for 24 hours.

according to above image, even when the phone is not awake or screen on, the battery drains fast.

i tried safe mode, but didn't work.

then i uninstall all my applications, it didn't work eather.

then i did a factory reset.

then i repair the OS with PC companion.

nothing worked for me. this issue is there for whole last month. i tried lots of battery saving applications, but nothing worked.

as i observed, the stamina mode is not making any difference, whether it is on or off.

what can I do for this? is this a problem of stamina mode?

I have android 4.3 build 15.4.A.1.9

I'm willing to bet that it is software issue comparing to 15.1.C.2.8 and 4.1.2 with which phone came. If this next update does not satisfy me, im downgrading for sure

isn't there any solution for this...?

[madura]

 if I install a custom rom of kitkat, will it solve the problem? will I loose battery saving modes like stamina mode, if I install a custom ROM

[madura]

what happen when I repair the phone with pc companion? will it remove the existing os and install a new copy, or just do some repairing like replacing any damaged files?

THE SUPPORT FORUM IS USELESS AND HELPLESS.

WHY DONT SONY REPOND TO ISSUES. BATTERY DRAIN IS A MAJOR ISSUE AND WILL BRING DOWN TEH BTRAND CREDIBILITY.

NOT A SINGLE ENCOURAGING COMMENT.

THIS IS STRONG MESSAGE TO PRSOPECTIVE BUYERS OF SONY MOBILES - DONT BUY.

IF ALREADY BOUGHT, LIKE ME, THROW IT AWAY, SO YOU WONT LOSE YOUR COOL DAILY.

Hey guys, I too have the same problem & I resolved it..!

No need to do anything neither it is update problem..

Just uninstall those apps who claiming that they can expand your battery life, It's all fake.! Guarantied..! And the battery draining problem only occurs in those phone in which such types of battery related apps, insatalled.

I would like to share the process which helps me to resolved it.

IF YOU INSTALLED ANY APP RELATED TO BATTERY LIFE:-

1. Connect your phone to PC.

2. Go to file manger of your phone. then open internal memory -> android -> data -> and delete the folder.(if you installed such battery related apps)

3. now uninstalled that app.

4. reboot.

IF NOT INSTALLED SUCH TYPE OF APP

1. open playstore and search for apps which can clean your phone's junk. (I used clean master)

2. run it once & let it clean your phone.

3. reboot.

This is what helps me now my battery life is same as before. You should try it once.

JazakAllah
