Help Galaxy S2 Shuts Down

[djqbert]

Hey guys ! I have Galaxy S2 and it shuts down frequently. To restart i have to take off its battery. For example on last night i left the phone when it had 69% charge on it but when i woke up it was closed with 0% battery (all apps was closed ) im worry about viruses. Please help thanks !

Do you have the latest firmware?

 

[djqbert]

Yes i do. Just updated on yesterday.

It could be a simple battery calibration issue. Try discharging the battery completely again, then charging it completely with the phone on, then remove the phone from the charger, turn it off and connect it again until it's fully charged.

Done that already not working. Problem is shuts down once a day.

Do you have any other batteries lying around that you could try? Could be a faulty battery (even if it's been working fine, they can develop faults).

If it was a virus I think you'd see other problems too.

Galaxy S2 has only been out a year!

You can pick up a spare battery for about

You can't do anything about that, other phones go into a low power mode rather than shutting down when you turn them off. I would charge your phone overnight and keep it on silent.

Could be a battery calibration fault. Charge the phone fully, remove the battery for 5 to 10 minutes , replace the battery, charge again till full. Gives the battery to re calibrate. All the best.
