In december 2013 I bought an iPhone 5s. A couple of weeks ago I restored my iPhone to 7.1.1 using a back-up on my Mac. Since then, the battery drains very quickly and the devices heats up most of the times even though the device isn't under heavy load.
Things I tried to resolve this:
- Restoring the iPhone to factory defaults using iTunes with the original ISPW file (and later using the device itself)
- Turned off iCloud, Mobile data, Background refresh and even turned on Airplane mode.
- Resetting the device by holding the power and home buttons for a couple of seconds.
- Recalibrating the battery (100%-0% and back to 100% again in one time)
- Sending the iPhone to Apple, they replaced the battery but haven't tested anything since the problem is still here.
- Using the iPhone for 15 minutes will drain the battery ~20%.
- Device gets hot sometimes even when I'm just reading an e-mail or responding to a text (so no gaming or intensive Apps that would trigger higher CPU load).
I connected my iPhone to xcode's console to log some things this is what happens every 30 seconds or so:

I think that something is triggering the iPhone's CPU since the devices gets hot too. Is there a way to find out what is draining my battery or should I send the iPhone back to Apple (again..)?
