Hey everyone, I bought my iphone 14 pro max at the end of January 2023 and at 15 July my battery health dropped to 99 %, I heard that it usually drops after an year or 9 months of usage but mine dropped after 7 months.
is this worrying?
Perfectly normal.
Batteries degrade over time with usage due to chemical aging, that's just how they work.
You can expect about a 1% drop per month with average use on an iPhone.
Apple recommends replacing it when it reaches 80%. To check your battery health, go to Settings > Battery > Battery Health.

Only to 99% in 6 months is, frankly, doing great.
See this excerpt from the "Your battery's maximum capacity" section of the support article: iPhone Battery and Performance - Apple Support
"A normal battery is designed to retain up to 80% of its original capacity at 500 complete charge cycles when operating under normal conditions. The one-year warranty includes service coverage for a defective battery. If it is out of warranty, Apple offers battery service for a charge." In other words, if maximum capacity is below 80%, the battery is below normal performance. You can still use a device with a lower health percentage than 80% but for optimal usage you may wish to consider having it changed when it reaches 80%.
Batteries are consumables and 1-2% loss per month is perfectly normal. According to iPhone Battery and Performance - Apple Support , Apple apparently only considers it unusual (and warrant-able) if a battery drops below 80% maximum capacity in less than a year after you receive it. Ergo, some storage loss as you use it is expected and acceptable. Incidentally, that possible 20% drop over the first 12 months equates to 1-2% drop per month being within the range of what Apple finds acceptable.
No one knows. Even if the phone drops 1%, it might not be really 1%.
For example, a Battery Health reading of 92.9% will be displayed as 92%. So if the phone dropped from 93% to 92.9%, it really only dropped .1%......yet it will look like it dropped 1% because of rounding.
Best if you not worry about the battery and check it maybe every few months or so.
Okay thanks, so when is the next percent going to drop? After a month ?
