Hi! I got my iphone 12 on january this year with the battery life at 100%, and now after 3 months of use it’s at 86%. I have a 20W charger and charge it only at nighttime and usually don’t let it drain below 20%. Other than that the battery usually lasts me through the day without needing to charge it. Should i be concerned? Did i get a defective battery? Should i think about replacing a battery soon or just buy a new one? Please help!
The iPhone 12 was discontinued on Oct 2022 so the phone is at least a year and a half old, and possibly older. 86% is pretty average for a phone of that age.
You shouldn't be concerned, you have a good 6 months or so before you should replace the battery.
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. This is an approximation, that is why it may be plus or minus a few percent on a month to month basis.
Apple recommends replacing it when it reaches 80%.
