Unknown batery drainage

Neurosoup — Tue, 08 Jul 2014 19:35:42 GMT

Hello,

Today I had an unknown batery drainage - phone went from 40% batery to 3 % in 2 hours, without any app or call during this time. I had only mobile data and wi-fi on, but nothing was updated during that time. Even When batery went to 15% it went into batery saving mode (no m data or wifi) and still the batery was drained when I checked my phone. What I noticed was the phone was very hot and now my unlock pattern DOES NOT vibrate when I use my pattern.

Are you using battery savers,task killers?

nope. Not a single app or other thing that could drain the battery. Was just strange that in so little time it was drained and now this issue with no vibration when unlocking the phone with the Pattern unlock. Any idea how i could fix the pattern vibration.

Usually it stops vibrating when on power saving mode - below 15%.

If you check the Battery Usage section of Power management, what are the top few apllications and percentage of battery they have used?

It seems pretty normal to me.Restart your phone and check if the same will occur again.

Is there a chance that the driver that controls the cpu frequencies got stuck and the cpu worked at 2.2 Ghz for that time? Because a power draining app should appear in battery usage, and since it looks normal from the screenshot maybe some power management driver got stuck.. (My opinion)

Yes,but I guess it should have showed up.A restart helps most of the time when something drains the battery.

I did a restart after the issue and it all went to normal, but since than I have no vibration on pattern unlock.

On a side note - the phone was veyy hot when the drainage occured and it was after some update from Sony`s apps.

Since than battery usage is normal, but still no vibration on pattern unlock.

Seems strange and phone automatically disabled the pattern vibration on power saving mode, but since than I recharged the phone to full 2 times and still no vibration.

In options,there should be something like screen lock sound.But I do not know about unlocking vibration or sound.Can you check how is it in safe mode?

Is the option "Vibrate on touch" from Sounds Checked? If is not checked the phone doesn't vibrate on system elements like back, home or unlocking pattern.'.

vibrate on touch was turned off. But it wan't me who turned it off. I guess some update (app or sony apps) had it turned off,but surely it wasn't me.
