Hello!

I have a problem - my phone is not going into deep sleep. Statistics at settings show that Android OS process drains around 15-20% of battery overnight. Wakelock Detector and BetterBatteryStats show that the source of battery drain is EINT wakelock and ttyc0, which make the CPU work at 1 GHz frequency 99% of the time.

3G, 4G, Wi-Fi, GPS, different synchronizations etc. - everything is disabled and still this problem remains. I even did a hard reset and tested it on a totally clean firmware without any additional applications - only those that were in firmware. Didn't help. My firmware is 4.5.4I (International).

Awaiting for a response from a tech support, because I am not the only one with this problem: lots of M2 users from 4pda.ru and XDA forums also reported this issue and we haven't been able to find a workaround yet.
