Just noticed with one of our phones that no charge issue appeared to 5.1 too after rolling back from 6.0.

Method used rolling back:
Sp-tools flash and 16042016 dated ROM

Phone barely charges battery with 5.1, similar issue as 6.0 had. Phone has been on charger 10 hours, maximum charge 320mA, most of the time phone is in tickle-charge mode, battery state after 10 hours of charging 10%.

Either 6.0 update killed battery in three days or there is some "left-overs" in this phone from 6.0 which causes problems. Not happy at all as before 6.0 update phone worked without issues with 5.1.

Hi,

Latest Rom 5.1 from 16.04.2016 has serious issue also. It is also very slow and freezes.
Tha best it to avoid Android 6 and Android 5.1 from 16.04.2016. Both of them are poorly programmed....
Flash to an earlier version.

This Rom is from 04.03.2016...

You can go further back to other versions if you want.
