M7350 Not charging properly
I had bought the device last year, I barely used it as im using it only for back up purposes. On the first time use I already noticed that the battery charging were getting stuck between 60% and 75% (random). During this pandemic I had a chance to monitor the behavior and the below issues were also seen.
* The battery isn't getting fully charge while is in used and plugged into the power source.
*The battery were getting too hot(random)
*The battery level for say is currently at 60%(during charging) but when you turn off/on the device the battery level would appear lower (e.g. 52%, 45% (random).
* The battery can sometimes fully charge to 100% but it takes a whole day and the device should be turned off.
Had tried several charging cables, chargers I have even bought a new battery but the issue still persist. To my surprise there were some bad feedback with the same issue with my local supplier in my country(PH).
The product I bought could be a factory defect one or just need a firmware update. If you guys please help me to figure out what might causing these problem.
Hoping to hear from you guys soon.
Cheers!
