Why is brightness 0% when remaining battery is less than 5%?
Cause
- When the charge on battery is less than 5%, battery is dissipated fast due to existing settings (Brightness, CPU).
- When battery charge falls below 5%, brightness is adjusted to 0% to enhance battery efficiency by restricting
unnecessary features.
How to fix
- Please be assured that it is a normal feature introduced for Optimus G and later models.
(Other manufacturers also have similar features)
