    When you run a phone battery flat it puts the chip in the battery into a coma.

    Plug into the factory supplied charger and wait. Don't push buttons and try to wake it. Every time you do it disturbs the cycle. If you don't have the factory charger, then connect to a USB 2.0 port on a computer as this is an expected input current as well.

    Leave the phone plugged in and wait. It may take several hours, but the phone will then wake up and boot. It will start charging normally at that point from some low percentage (6% or even less). Let it charge to 100% before disconnecting and then resume normal use.

    Try to avoid improper shutdown from battery drain and attempts to wake the phone anyway. These things degrade the battery pretty stressfully.

    Looking around at some of your other posts, I believe your battery has already been critically stressed and is in need of replacement. If you cannot replace it yourself or find a shop to do this you may want to start looking for another device.

    It turns on ... THX
    But there is a problem , when it is charging 20% it jumps to 100% directly and I restart it and did soft reset it shows me 95% and complete to 100%
    But with use over WIFI & Whatsapp suddenly shows me " battery critically low " and turn off . I turn it on the battery 90% after use for few Min. the message appear again and turn off . I turns it on show me 3% >>> It is a phantom charge ... What should I do ?

    I'd try using the WPRT to revert to 8.1 Update + Denim official.

    This will help reveal if the battery is fault or something in the preview.

    However, if you have been on Insider a long time and had to revert to 8.1 to get the latest builds and did this over and over, you may have taxed the battery.

    Official is the best way to gauge your battery's health.

    Did you try to revert to Cyan and see if that works?

    Also, how long did your battery last while you had the 8.1?

    You will need a new battery. It's not caused by the OS, the battery has just worn out.

    Your battery is worn out. Forget blaming the OS or the firmware. The battery needs replacing - simple as that.
