Help Samsung Galaxy SII Battery decreases (drains) quickly!!!

[AmgedIsmail]

i have noticed that the battery quickly drains even without using too many apps.

Yesterday I was only outside turning on the Wi-Fi searching for any network that didn't take more than 8 minutes I am sure.

I also tried out the video camera again in the street and that didn't take more than 8 minutes as well...

So the total of time using the phone might should not be more than 16 minutes.

And when I returned home I found 6 percent has decreased, it became 94 % of battery.

Can 20 minutes really decreases 6 percent?

Yes. Play heavy duty games, it might deplete the battery in 2 hours. Play movies, its about 3 hours.

Its a smartphone and it takes juice. For most people, its a daily charge. You can however check the battery consumption in the settings locations and see if On Screen time roughly corresponds to the Awake Time. That way at least you know there is no app keeping your phone from sleeping. A good way to make sure battery last longer is to off data line. Long press on power and select deactivate the data.

Cheers

Data network mode is already deactivated.

When I hold the power button it showed:
