Just thought I'd inform all G2Touch and HTC Hero users of a decent battery
I've just bought for my T-Mobile U.K. G2 Touch.
Had my phone running since 7.30am and it's about 3.20pm now and only have had a drop of 10% in battery power so far.
Very impressed.
The battery due to it's size has it's own back cover for the phone, which adds an extra 5mm to the depth of the phone. Not really an issue in my case to be honest.
If you hate having to charge your phone constantly look up "3000mAh battery for HTC Hero" on google. I picked mine up for a cheap £17 (inc postage).
