  • Not helps. I think android force disable power saving when connected and return when disconnected. How to disable this behaviour? Commented Jul 18, 2018 at 9:18
  • I think Android forces "Power Saving" to keep turned off when the device is charging.

I found out that some cpu optimisation disables when phone connected to devices that suport data transfer (netebook for example (even sleeping), or my solar cell), so i use usb cable that not support data transwer.
