I've had the same problem battery drain only 15 hours I have turned few wifi settings off

  • Smart network - off
  • Keep wifi on during sleep - changed to only when plugged in (would have thought this would be default)
  • Always allow scanning - off
  • network notifications - off


Hope this helps someone last 2 hours only lost 1-2%

For fast charging always use the wall charger. When using the original charger that came with your phone and the original cable (USB 3.0 compatible) your device can pull the full 1800 mA from the charger, since it can sense that the charger is able to handle this safely. When you use a USB 2.0 compatible cable it will only pull 1200 mA from the charger, even if it's an original Samsung wall charger.

Ok. I am using now this kernel ktoonsez KT-SGS5 and with a normal USB2.0 cable I get 1000mA from my USB3.0 port and get 1800mA from my wall charger.

Cool, that means in this kernel some of the original power management restrictions have been removed. It would be interesting to see if the limit on charging via the contact points on the back of the phone (used for Qi wireless charging and by car mounts like Mountr that use inductive charging) now als can accept more than 750 mA...
