I?m pretty sure the battery level went down to half after going full power for a few minutes going up a hill. I switched back to PAS 1 after the hill, and the battery level seemed to go up 2 bars a few minutes later.

Weirdly, going PAS 0 doesn?t seem to cause the readings to go higher.

Does anyone have any insights as to why this happens? Also, how can I get an accurate gauge of the real battery level (for maintaining battery health)
