Hi, I recently bought an iphone 15 plus and I am observing that it stays at a particular battery percentage for a long time then drops 2% in only around 1 minute when I keep it idle. Battery health is 100 % and I am on latest ios 18.2 I have also tried manually calibrating the battery (draining full battery till it switches off and then charging it to 100%). Is anyone else facing the same issue or knows how to fix this?
Thanks
Batteries, like people are individuals. No two people age exactly the same and batteries don’t age the same either. The exact usage, chemical makeup, storage conditions, exposure to heat and cold and about a dozen other factors mean that every battery ages differently. Battery aging is not a linear (straight line) and degrades at different rates as the chemicals in the battery age and other factors mentioned above. Apple expects your battery health to be at 80% after 24 months. If your battery health misses that expectation, contact Apple Support.
Please review the Apple Support articles on battery optimization. It contains the best current practices for battery charging.

Hi Jeff,
But my question is, is this behaviour which I mentioned of battery normal? Considering its 1 week old phone with 100 % battery health
