Hi
I have this problem too. Since I updated my ios from 10.2.3 to 11.1.2 version. I feel my battery life is shorter than before .
I have a app with name ( memory & disk ) , When i do not have anything in background on my iPad, and check my cpu activitys , Memory&Disk app shows for a long time 14% to 20% tolerance cpu activity sometimes. I feel exactly the power of the cpu is less than before.
For example. I has one setting in cubasis with combination 3 apps in background that it work very soft and properly in ios 10 , but in new ios 11.1.2 that i use same setting with same 3 apps in background, i hear noisy sounds and when check with Memory&Disk app shows cpu 60% to 80% .
I feel this is a problem with the operating system.
Can you help or report this problem to ios Apple support team. ?
