Hello.
I have Meizu M5 Note Flyme 7 with roughly 5 months usage, and now I'm facing an issue.
The phone worked fine until one day the fast-charging feature doesnt work, it takes 5 hours to full-charge.
Days after that, The phone dies instantly at 40% battery, then just instantly died after I remove it from the charger.

Performed a factory reset and battery calibration, didnt give a good result, phone keeps shutdown after 2-3 minutes usage.
I assumed that this is battery problem, but last night I just left the phone discharged on idle position and find that the phone didnt even shutdown / die for a night full (the battery only dropped 3%), so I think it is not a battery problem.

Anyone has this kind of issue before? How to fix this? Thanks
