i normally put the phone to charge overnight. I noticed since last few days once it is fully charged and i take it off the charger the charging light continues to remain green and if i press the power button or menu button it takes around 1 minute to wake up. Also today i noticed that if i did not switch on the phone the green indicator light remained green for around 4-5 minutes. Is it normal and if any one else is also facing the same problem. Other than this i don't have any problem with the phone other than already known issues. I've not rooted the phone and all latest updates are applied. I've an i9500.
