    Does your phone shut down below 90% battery capacity and refuse to turn on till it's plugged?

    Before buying a new battery try the steps below.

    1) Remove the battery.
    2) Drain the battery.
    3) Place battery back in phone and charge to at least 99%.
    4) Turn phone on and verify all is ok.
    5) If the steps above worked for you - remember to unplug phone when fully charged and let drain to around 15% before recharging.

    How to drain battery:
    Connect a load to the + and - of the battery. The load I used was a 5v DC cooling fan - took over 12 hours till it stopped spinning. Other load options are flashlight bulbs. If using LED bulbs do ensure correct polarity for the LED to light up.
