My warranty is well over (bought the phone in December 2012) and my battery is not what it used to be anymore, perhaps it's time to change it. 1) Is it worth to buy one of those DIY kits (25 dollars including battery) or is it better to just leave it to a "genius", spend real money and avoid the hassle and the risk of a homemade procedure? 2) if I had to go for the DIY route, have they created any new battery in these past two years? I mean, is there anything above 1440mAh that I could fit into the iPhone 5? Thank you for your help.
