Hi Guys

[franekz]

Hello.
After many years of being a Symbian user and developer (M2M systems), now I have moved to Samsung Galaxy S II. It looks nice but the battery life is killing me. Not a very good start - rooting phone etc to have it working properly.

Thanks
Peter - still permanently connected to the charger

Welcome to the AndroidForums, Peter.

Yeah, its kind of a balancing act with these little mini-powerhouse computers we call smartphones .

Turning the brightness down on the screen, using wi-fi when available, using 3G when 4G is not needed, and reducing the sync interval for various apps can all contribute to a little longer battery life.

There's also the extended battery option, too, but you might check the specific SGS2 forum for your carrier for any other tips folks might have.

Cheers and glad you signed-up with us here at AF.

Welcome to Android Forums!

Peter, especially if it's a new phone, it's important to teach your phone the capacity of the battery. Many times a phone is not completely charged the first time and the phone will base it's reporting on inaccurate information. Try this...

Let your phone completely discharge. Leave it on until the phone shuts itself off. Then, without using it too much, plug it in to the a/c charger (not the USB cable) and let it charge to full. When it shows a full charge, unplug the phone and reboot. Then shut the phone off and plug it back into the charger. If plugging it in boots the phone, when it is completely booted, shut it off while still plugged into the charger and let it charge for at least an additional hour even if it says it's fully charged. Finally reboot the phone.

You've now taught the phone the capacity of your battery and it will be able to more accurately report the charge (and you should see longer battery times).

Modern LiIon batteries do not require conditioning and are actually susceptible to damage if you constantly deep-discharge them. They perform much better and last longer on short incremental charges.
