iPhone 4 has been around for over a year now. Battery run time could now be noticeably shorter than when it was new. It could be time for a new battery.

Our new internal battery for iPhone 4 will get your iPhone 4 running as good as new in terms of battery life and it's much easier to install than older iPhone models. Our battery comes with instructions so almost anyone can replace their battery.

Maybe the internal battery is still good.... or not. Either way if it's more run time that's required how about one of those protective covers / bumpers 7 for around the same price as the other protectors but with a twist! A super slim battery also built in that more than doubles the runtime of an iPhone 4
