draining battery - deep sleep doesnt work (pic included)

Divi45 — Wed, 26 Feb 2014 08:11:57 GMT

Hey guys...

Usually my Xperia SP goes 2%down during night...but all of sudden,yesterday it went 40%down during the night. I really have no idea why this is happening... I included 3 pictures from the BetterBatteryStats app, it looks like that my phone wasnt even in the deep sleep because "Awake" stat is 15hours (that is probably the time since i unpluged the charger when it says 100% charged)

I think it is from the fast dormancy that has been reported on many devices.Do you keep your phone on GSM/WCDMA?Also,I suggest removing all kind of battery savers,task killers.

i dont have any batter savers or task killers... my phone is on "wcdma (prefer)/gsma" ... however, I found out that it i caused by the "msm_otg" process on the first picture which keep the phone from the deep sleep....but I didnt find any solution

I suggest you change network mode to GSM only and you boot your phone in safe mode:

msm_otg solution

I found the solution. (xperia M2 4.3 rooted)
[B]Just replace the usb cable and it's ready. Use the one came with the phone[/B]
The msm_otg appeared to me each time i disconnect my charger. I used an old cable that was for charging only. The problem has to do with the usb cable's fifth pin or something i don't want to research. I just used the usb cable that came with my phone and msm_otg is not appeared anymore when unplugged charger.
