Hi guys. I just bought a brand new Sony Ericsson Live With Walkman WT19i. I love it, but I found the battery to be a bit insufficient. It's a common problem with Android phones, I know. The battery rating is 1160 mAh. I'm planning to buy a new battery for it,(Genuine, and made by Sony Ericsson), which is rated at 1500 mAh. I want to know, how much of a difference will it be? Is it worth buying at all? I want a well explained answer. 10 Points for sure if I'm satisfied. Thanks in advance.
