Phone Model : HTC Sensation Z710e
Status : Unrooted
Since I upgrade (official upgrade) to ICS 4.0.3 my battery is having an unusual problem. Say if I charged the phone to 100% and keep it, the next morning the battery drains out to almost dead without any wi-fi,bluetooth,data connection.
I have tested some other things as well, after it is 100% charged, if i power off the phone, remove battery and put it back and power on the phone, it still drains like 4% of battery in that 1 minute. Sometimes it is more. I have checked the battery and it is in good health.
Could it be due to the OS or something? How do I fix it? Please suggest
