iPhone 14's battery health is at 89% after 9 months

Please do not obsess over an inexact metric. Look how the Health reading on my wife's iPad 7 have jumped around over three years:

[from Coconut Battery app's history function]

Hers is right at the 80 recent mark and still has acceptable runtimes. I find that shortened runtimes, assuming no other battery issues, start to appear around 70 percent.

Her iPad uses the same basic power technology as your iPhone

No. You can expect a loss of 1-2% each month. If the health falls below 80 percent have the battery replaced.

Your battery is right on schedule. Expect a decline of about 1% a month. This is normal.

Replace the battery when it's down to 80%

Hello~ To add to *muguy's* information...once you need your battery replaced at 80% take a look here by clicking on...

Mine is 97% after 15 months of use. I never charge it overnight. I have a shortcut to sound an alarm at 80%, and I remove the iPhone from charger.

i purchased my iphone 14 in 27/1/2023 and now it’s 89% battery health after 10 months 25/11/2023

is it normal??! What should i do i charge with original charger and charge at 20% to 80%

should i make the battery dies at 0% and charge it to 100% once per week?

Did you even bother to read the previous posts that explain this perfectly normal behavior?

iPhone 14 battery is terrible. Apple doesn’t want to acknowledge this but when I went to the store they suggested I should have ‘researched the phone before buying’.

The solution offered was that you don’t use apps and stop background refresh.

Really good stuff 🍏

I am literally thinking of that too…. My first iphone is the iphone 14 which I am using right now…. I am charging it from 20% to 80 a the battery health is at 88 after 9 months. so after one year i would have to replace the battery that costs 120$. Good one apple

I assume your a heavy user most likely 8 hours + each day. I hate that Apple started showing the battery health but once it hits 99% then expect it to drop more faster

I have the same problem with battery health check only 89% less than a year. Very upset with this product,14 pro

Same here! 14 pro is my first and definitely last iPhone! Apple ought to be ashamed of themselves!

My iPhone 14 PRO battery is at 89% only after 6 months of use!

i have a 7months iphone 14 pro and my batt health is 94% i feel like it goes down every week or every 2 weeks after i updated the new IOS 17.2.1. is this normal?

If your battery health is at 94% after 7 months, that's less than 1% a month. Not sure how you came up with the math that's its dropping every week or two.
