Hi. I'm a newbie to the Galaxy S2, had it just over a week now and I previously had a Galaxy Fit, my first Android phone. The S2 is so much nicer but it does use the battery quicker. I disable everything I don't need on and also turn off the data usage when it's just idle at home. I've read a lot of comments on here about higher capacity batteries and wondered if the ones sold on Ebay and Amazon are safe to use. I'd like to get a better one but I don't want to change the back of my phone, if possible.
Can anyone tell me if they've had any experience of these cheap batteries and hopefully what size I can go up to and stay with the standard back? Also, my phone is white and I don't fancy having a black "hunchback" on it.
Thanks in advance
