Hey guys, I just got my iPhone 4 three days ago and I've started to see issues with the battery. There have been plenty of threads discussing the problem where the phone continues to stay on usage. Essentially the battery will lose 40% of it's juice on lock in a few hours, which is terrible. So I have tried a number of things, but finally resorted to restoring my phone to it's factory settings- hopefully this does the trick. As a first time iPhone user I have some concerns. Will restoring my phone in any way effect the phones performance, memory, etc. (Any downsides to doing this, aside from the fact all saved data will be wiped)? I don't want to see a decline in performance already....it's only been a few days. I'd really appreciate some comments from you guys, thanks.
