Dear NOTHING Support Team,
I have been using the Nothing Phone 1 recently and have encountered a significant battery drain issue.
To address this, I changed the display refresh rate to 60Hz. However, I noticed that when my phone battery was at 27% and the device was not in use, it suddenly dropped to 19% within just 15–30 minutes.
Kindly look into this matter and provide a solution or release an update to fix this battery drain issue.
Worst experience in battery drain.
