Ambrane India — Battery percentage confused me

Ambrane Stylo N2 was like a good backup, but the battery percentage on the power bank was a little confusing. It jumped from 3 bars to 1 bar quickly, so I could not properly judge how much charge was left. I contacted support, and they said it can happen after the first few cycles and suggested doing a full charge and full discharge once to settle the readings. After that, it seemed more predictable. Backup is still decent for long days and the charging speed feels okay for daily use.
