YI4K PLUS Battery Drain

[Nihal]

HI All
I have the YI4K Plus Action Camera with the battery drain.
Attached please find picture of YI4K Plus with front cover removed.
I cannot see where the fix should be done.
Can anyone please help.
Kind regards

Did someone find a fix about this issue, because I have 5 batteries and even charged at max when I turn on the camera, it starts to show different percentage of power and change it after 5 seconds
