UMI Hammer shuts down suddenly

mck

every now and then, UMI Hammer phone shuts down suddenly - battery level is usually under 60%...
Any advice on that?

This situation is happening every time that battery arrives to 60%? Is there any time where battery is discharging normally until arrives to 0%?

Hi. I have the same problem. It happens several times when the battery is between 30-40%. Morevoer, the phone can be during a long time with a 1% battery.

Hi,

The voltage of your battery probably drops suddenly when the CPU works with high power, causing an immediate shutdown. Your battery might be overused or shoddy. I suggest you to buy a new one.
