I've had problems with my iphone 5s and the battery life. When I went to the apple store they were able to run a battery test that showed me what apps were using the battery, what my cellular connection was like at that time, etc. Are there any apps that can do sometime similar? Show me my battery's history, so to speak, so I can assess what's been using all the battery power? I've found several battery doctor apps or whatnot that seem to be designed to preserving and making the battery more efficient (and keep telling me to do things like turn off my wifi) but I'm looking for something to show me what I'm doing that's using all the battery because I can't figure it out.
