iPhone 15 battery health dropped 11% after 287 cycles

11% battery health drops just 287 charge cycles on my iphone 15 (1 year 16 days age) with normal usage maintaining 20 to 90 charging pattern . No gaming just use normal social media apps . Daily battery usage in between 60 to 80%

.

How is this considered as normal and expected from apple customers support team?

This isn't Apple Support Team. This is a user to user only forum, which Apple neither participates nor reads for user feedback.


On average, your battery will lose approximately 1% per month. You've owned your phone for going on 13 months and you've lost 11% in battery health. There's nothing unacceptable about what you're seeing. What would have been unacceptable would have been to see your battery health dip to 80% in 12 months and had that happened, it would have been replaced under warranty. But your phone is operating within normal boundaries.


Most of us senior members here don't use the Charging Limit. We use Optimized Battery Charging and we plug our phones in to charge when we go to bed at night and leave them plugged in all night, every night. We wake to a fully charged phone, which should have also backed up while we slept.


When your battery health dips to 80%, that's when you'll want to schedule an appointment with Apple to have the battery replaced. If you had purchased an AppleCare+ plan when you bought your phone, the cost to replace the battery is $0. If you didn't buy AppleCare+, the cost is $99 (in the US).

Battery ageing is not linear, the health curve tends to settle around 85-87 for the second year.

There is absolutely no reason to limit the charge to 90%, it is an Apple placebo placed there to make you think you are being careful. It is particularly unwise if you worry about the day's capacity.

Most of us will recommend charge to 100% all night (to limit off charge dead usage cycles), every night using optimised charging, not charge limit.

No two batteries age the same because they are all slightly different chemically and are used and charged differently. So, averages are arrived by comparing millions (billions?) of batteries and coming up with a middle number. Yours is just aging differently, not better and not worse. Just different. Understand it, accept it and don’t worry about it.

There’s two issue here, does it actually benefit the battery, long term and/or short term, and is the benefit noticeable.


So, while the benefit may be measurable will it improve your day to day usage? In my case, no, I need the full capacity of my battery on a daily basis. I do not always have access to a charger or external battery. However, your daily usage may be lower than mine and perhaps you have more ready access to a charger, battery etc.


My personal charging practice is to use optimized charging and charge to 100% every night. I have enough charge that I don’t need to top it up during the day and at night I’m not below 20%. This routine has worked for iPhone batteries for 19 years. Long before there was optimized charging. In the old days I did have to replace a battery occasionally (iPhone 4S and 7 plus). I still have both iPhones and they both probably need a new battery. 🤣🤣
