Fake charging on a phone or TAB
Charging not increase knows as fake charging happen due to:-
- when charging point is very weak due to water damage or over used
In this case is recommended to change charging point or sub charging panel, it will be better to clean area very well and resolder led area gently to make connections storonge to avoid shaking
- It's maybe lack of connectivity between charging plus (vbus) line to charging ic
Try to apply jumper from charging plus to capacitor that work with charging ic for fast cuurent supply
- It maybe battery line capacitor or diode not okay and it's reverse the current without pass it to battery
This can be happen when over current or charging accident hppen and troubleshoot the capacitor or diode that helping battery during charging it, it will not allow current pass through it to the battery
- it maybe charging ic is not good or its its also damage by water especially crystal glass
Water can Couse everything in mobile phone include not charging or weak charging when vDD bridge with gnd or somehow short
- When battery is not good or it dry to solid it will not charge also or it will slow
The battery has liquid water inside it can be dry when it energy finish, over used or over charging (always on charger) you need to try another battery if all above circuit are ok
- Or use xener diode method to bypass the charging......
