Heavy battery drain? #1357

Open neutralinsomniac opened 2 days ago

neutralinsomniac commented 2 days ago

I'm on the DM42, and my battery voltage has dropped to 2.7V within 3 days of very light usage of db48x. Is this expected?

c3d commented 15 hours ago

It is relatively expected, in particular if you used a no-brand battery.

Can you try comparing with the same brand and running the reguar DM42 firmware?

Yes, I flashed back to stock firmware and the voltage settled back to around 3.0V. Switched back to db48x, and battery sagged back to 2.7V.
