    Hi,

    This is a fix for people who only have an hour of battery in windows.
    You have to change the critical battery action :
    To change the ‘ Battery-> Critical battery action->’On battery’ setting to “Do nothing” using powercfg.exe
    1.activate the power scheme you want to modify.
    2. open an elevated command console (windows key, type ‘cmd’ in start menu, press “ctrl+shift+enter”, click ‘continue’)
    3.execute “powercfg -setdcvalueindex SCHEME_CURRENT SUB_BATTERY BATACTIONCRIT 0”
    4. your current power scheme will show “Battery-> Critical battery action-> On battery: Do nothing” despite the option being unavailable in the drop box.
    After this, must use the tablet until it turns off (the mine was running at 0% for 3 hours).
    Now we will have to charge up to 100%.
    And voila, 5 hours of battery!
    Note: Do not perform anything critical during the period of 0% (move files, defrag Windows drive, etc) because we can damage the files of the drive.

    Thanks! I pasted wrong the command.

    Now is correct.

    Teclast really needs to fix the battery monitoring firmware.  With the cable disconnected my tablet reports that it’s plugged-in all the time, and it has been running for more than 1 hour with the battery indicator at 0%…

    I have been studying another bug of the battery control firmware today. After you connect a device to the microUSB port, the tablet switches the port to OTG mode, which is OK. But then it remains on that mode and the tablet does not charge when using the included charger and most other chargers.

    It seems that “smart” chargers detect that the port is in that state and do not give power to it. You need a “dumb” powerful charger that gives power to the USB port without checking the state, then it switches to normal state and you can use any charger. For me it works with the charger that came with my OnePlus One and a external battery.  Both rated at 5V 2.1A.

    Has anyone else tried this fix? Really adds ~2 hours? Is battery charged without problems?

    Yes, but  you’ll work with empty battery on windows indicator. 1.5-2h. If you control the battery voltage on Aida64, it will be better.

     

    PS: you should decrease Reserved battery level to 0%

    Where is the reserved battery level setting?
