@Blackview_admin My battery was at 25% no charger plugged, disabled the battery manager app that came with the android6,cleared the internal memory cache,shut down phone, disconnected battery,waited 30sec, connected battery,started up,connected charger and now charging. Did this 2 times but at first atempt it did´nt work. Noticed that when i started the phone and there came a message that "launcher not responding, do you want to close it?"(activated the function in developers menu for that notification) closed it and the phone became slugish but is charging. At the first atempt the notification did not pop up. Using an ampere app to monitor charging and it was giving me aprox 930mA constant. Todays test:when the phone is connected to the original charger it won't charge but when I switch to a cheap travel charger it immediately starts to charge the battery. I tried this several times and with differnent chargers always the same,after emptying the internal cache the original charger works but only until it's being unplugged and if I then connect the travel charger it starts charging. It will not charge with my huawei tablet charger either so I assume there is some different methods in the chargers how they output power to the phone. So now i have found a way to charge the phone and max is approx 920mA so it is slow but faster han the original/huawei tablet charger that gives a max 180mA.
When i installed the ampere app it sayed the first time of use "the phone is using an older measurement method, do you want to switch to the older method?" don´t know what that means but just as a notification
Today (27.5.2016) in the morning (phone was on all the time)the battery was fully charged and the app gave a voltage of 4,393v, measured with a multimeter the battery voltage and gave me allmost the same voltage.The charging stops if i open apps or take a screenshot but starts charging immediatly after i close everything but only with travel charger not with the original charger. So for charging i close all apps wia the long press home button and start ampere app for monitoring and plug the charger and leave it that way
