Hello all I have an iPhone 4s that just got a battery replacement. But the battery life seems to be subpar. For example, when web browsing this morning on a 100% charge, at around 1/3 brightness, after an hour, my battery dropped to around 70%. Shouldn't my battery be more than this? Is something wrong with my iPhone besides the battery? I have disabled many settings, such as frequent locations and background app refresh. I use auto brightness, cause that to me is much more convenient, but shouldn't my battery life be better? Another example: I charged my phone to 100% this afternoon, and based on battery usage in the settings app, I have had around 2 hours of usage, with around 6 hours of standby; I did various things including web browsing, camera use, GPS use, phone calling, etc. and now I am at 26%. Is there something wrong with my iPhone or is this about normal???
