Mi 4s Not Powering On

[sean winn]

Hi All,

My Mi 4s was working fine, then last night the battery didn't charge fully (only to 44%) then today I rebooted the phone and it no long powers up.

I can't get into TWRP or fast boot mode using the power + Vol up or power + Vol down.

Anyone got any ideas that may help me please?

Thanks all,

Sean

Press and hold the power button for what seems to be an eternity....about 2minutes...

Thanks all, my phone's back working again not sure how though. Left it charging all day and nothing no lights, no power. Moved it and plugged it in to a tablet charger and the red light stated to flash left it charging over night and 100 percent battery and phone working again
