iPhone 15 battery health dropped in one month of usage

I have Iphone 15. This is not my first iphone. I bought it on 30 december on my birthday. And now My iphone battery health is 95%. Only 1% battery health drain in first 3 months and after that every week My iphone is draining upto 1% battery health. Please help me. I am a middle class child. I can’t afford to sell and buy a new one. Please Apple help me or anyone know the solution or why this problem is occuring please tell me.

The phone is 5+ months old. Max Cap should be at about 95% by now.

Maximum Capacity is going to drop......on average.....at about 1% a month. That is an average. Some months in a row it might not drop at all and then drop 2-3% the next month.

Your battery is performing normally.....exactly the same as the two iPhone 15s here at the house that are both 8 months old and displaying a Max Cap of 92%.

After 12 months, Max Cap will be in the 88-90% range. After 24 months, it will be down to about 80%. Replace the battery at 80%

I have purchased october 2023 iphone 15, my cycle count is currently 265. and my maximum capacity is 93%. 10 days before cycle count was 246 and my maximum capacity 96%. my maximum capacity is decreasing very fast. and need solution as its the latest version phone and still facing this major issue.and i have people surrounding me also facing the same issue.

This is ridiculous because I got my iPhone 15 in October 2023 already at 89% cycle count 327& I don’t have social media mostly use safari …I’ve had my iPhone 11 that I gave to my daughter for 5 years battery health percentage 77% …

I purchased iPhone 15 on May 21 2024, now it's only 1 month 10 days and battery health went down to 98% with 43 cycles. Two of my friends have same iPhone they have 94 cycles 100% and 45 cycles 100%, is it normal for me?

Batteries are chemical products. They easily effected by environmental conditions. Apple guarantees that the device will not decrease more than %80 of battery health in 2 years. So if it ever decreased below %80 in 2 years at that point it is not normal. At that situation, the battery change made by apple. At ideal conditions iphone 15 should remain 80 percent of battery at cycles of 1000. But it is not guaranteed.

Apple doesn't warranty the battery for more than one year unless you buy AppleCare. If the battery drops below 80% in one year, they will replace it for free. But, without AppleCare, after the first year, the user has to pay for the replacement.

My iPhone 15 with 68 charge cycles has reached battery health 99% and I got it on May 1.

You do know that the Battery Health will normally decline about 1% for every 25 charge cycles, correct?

Your battery has had 68 charge cycles, so 68 divided by 25 = 2.7%.

So, it would be normal to expect that your Battery Health would be in the 97 to 98% range at this time. You report that it is at 99%.

Your battery is doing significantly better than average. If it keeps up at this rate, you might consider sending flowers to Apple for your very good luck with the battery.

I use 15 plus for 2 months plus now my battery health is 99%. I hate it when this happened cause I don’t use this phone regularly and i only charge it one in two or three days! I guess it’s just the same if I happen to use it regularly and charge it everyday maybe the time is half of what mine is. Also this is fine compared to my experience with 14 plus! In a year my battery health drops to 85%!

My iPhone 15 Pro Max is down to 95% I also bought the phone in Oct 2023 is now July 2024 9 months down battery health is down 5%

Wow, you have a great battery. After 9 months, it would be normal to expect that Battery Health would be in the 92-93% range.

Whatever you are doing......keep doing it.

Read this user tip, it will explain the battery degrading and why what you’re experiencing is normal:

About battery health on your iPhone - Apple Community

Your battery health will drop 1-2 percent per month; This is normal. Health would never drop 1-2 percent over 1 year, that would not be normal at all.
