Help New Battery

[jak68]

I am looking to get an extra battery for my S2 and was wondering if I am able to use a battery with a larger mAh or will these damage the phone

Only use the OFFICIAL extended battery by Samsung.
If you use the official one it will not damage the phone.

Amazon UK search for samsung s2 extended battery

This should give you an idea. If possible, visit a Samsung outlet and buy from there.
