Charging problem gear fit 2
 
Hi everybody!

I'm working on a samsung gear fit 2 that don't charge. I've tried pushing 10 seconds the buttons while on its base but nothing start (only a lighting during 1 second, nothing more).

I tear it down and take some measures :
I get some 5V power directely on the motherboard. I get some little current during 1-2 seconds (0.1 mA without battery, 0.3 mA with battery).

Then I measure :
battery disconnected I've 0.45 V at the pins of the battery connector while my battery is at 3.1 V (rated 3.85V).

Do you have some tips for me to go further?

Thanks a lot,

Chil_blc

I've googled it but don't find any information about this IC. Do you have a schematic of the motherboard?
Thanks,
