Some times my phone does not wake when i press the power button. While its on standby, i try to power on the screen and nothing! If i have a notification the led blinks normally but still i cannot power on the screen! Its like the phone is stuck... Cause i missed the alarm a couple of times. Also when that happens i observed that the battery drains too fast! Let's say i go to bed and then through the night the phone discharges like 2-3%. When that deep sleep thing happens the battery goes down by more than 20%! Please let me know if anybody faced sth releveant or could at least offer some help. Thanks in advance...
