My IPhone 15 battery health dropped to 99 in less than a month!

Same here. Bought my iphone 15 on Dec 17. Its been a month. My cycle count is 25. My battery health dropped to 99. No harsh usage. Was conscious not to overuse but still the health has dropped. How is your phone doing now?

Can you please tell me how do you use your iPhone 15? Will my iPhone battery health go down like 100%-99% if I charge my iPhone 2 times a day everyday & without using iPhone on charge & I keep lower power mode when it reaches to 79%. And I never let my iPhone to go down below 40% so charge my mobile upto 97-98% by not letting my iPhone to charge upto 100%. Hope I can get a help from you & waiting for your reply.

Thank You

I purchased my IPhone 15 on launch day on 22 September and my battery health is already at 99%,

So, the phone is almost 4 months old at this point and it has dropped only 1% ?

That is phenomenal performance. Some of the best that I've seen.

Normally, you would expect the Battery to drop at a rate of about 1% a month, so your battery really should be at 96-97% at this time.

Hi Pranav1603,

We'd like to share some information about the battery and to help show the expectations of battery health as this is can lower via chemical aging. We recommend looking over iPhone Battery and Performance - Apple Support. While this can be expected behavior, if you continue to have concerns with this, you can contact Apple Support.

Thanks for using Apple Support Communities.

Same as mine. Maybe after the new update. I always make it to a point not to overcharge etc. But still went down to 99%

If it was my iphone 15 pro behaving like that, I’d go to the Apple store to have it checked
