I have recently experienced abnormal battery charging and battery behavior and would like to know whether this indicates a hardware issue covered under warranty.
Issue description
The camera begins charging normally, but after reaching a certain battery percentage, the charging speed becomes extremely slow.
Initially, it may charge quickly, but after reaching approximately 20–30%, it slows down dramatically, sometimes increasing only 1–2% over 8–10 hours.
If I unplug the charger, allow the camera to cool down, and plug it in again, it will often charge another 3–5% quickly before slowing down again.
Using this method, I have only been able to charge the battery to approximately 60%.
Troubleshooting performed
I have tested the camera using:
Anker 30W USB Power Delivery power bank
Original USB-C to USB-C cables
Original wall adapters
Multiple charging sources
The same behavior occurs regardless of the charging method.
I also tested the Battery Handle. When attached, the camera charges quickly for 1–2%, then charging slows down again.
Battery behavior during use
While recording (especially in 4K), the camera operates normally until it becomes warm. On several occasions, the camera has suddenly powered off and displayed an empty battery even though the battery indicator previously showed approximately 30–35% remaining.
Additional observation
When the camera is connected to a charger or the Battery Handle, I can hear a faint intermittent buzzing sound (similar to "zzzz... zzzz..."). I am unsure whether this is normal.
Camera condition
Apart from the battery issue:
Recording quality is normal.
Battery drain while recording appears normal.
Gimbal stabilization works correctly.
Autofocus and ActiveTrack function correctly.
All other camera functions appear to operate normally.
I contacted Dji support just want to know if someone else has experienced this?
