Battery Health Capacity Dropped

I got mine about 2 weeks after launch due to back orders my iPhone 11 Pro Max is down to 98% already. My iPhone XS Max didn’t drop at all for about 7months I believe the issue is the fast charger it’s killing the battery health a lot faster.

I wouldn't count on atypical behavior being repeatable. 98% if you got it soon after launch and actually use it on battery power? That's well within expectations.

don't worry about what the numbers say

if it's not at 80 and below nothing will be done unless you spend the cash

I've had battery drop very fast first few months, even to 82% before - lasted for years until hit really died

I've had battery stay at 98% the whole life from new and die a few years later at 98% while apple was telling me my battery was fine.

If you get the hours you expect - don't worry about what that says

Apple has made it known what their battery design goals are. I've had some devices that I got that were under 100% but I knew there wasn't much I could do about it. I've also had the battery that wouldn't die no matter what I threw at it.

Yet many still persist that because "I saw this before" or "my brother's did better" that a steady decline in line with Apple's published specifications (80% after 500 cycles) is somehow wrong or they've been cheated - just because they didn't see that better than average performance.

Honestly we're kind of spoiled these days. I remember the days when a lithium rechargeable battery was expected to last 200-300 cycles before a decline to 80%. We're at a rated 500 to 1000 cycles for all Apple devices now. I suppose they could probably increase it by "overprovisioning" the battery capacity where less of its charge range is used. That's likely how larger Apple device batteries are rated for 1000 cycles.

So I have restored my IOS & the battery read 100% after it was reading 98%, it stayed at 100% for a week.

after I used my belkin wireless charger the value decreased to 99%, maybe this can be a fast charger/fast wireless charging issue.

has anyone who had the issue used wireless charging ?

Apple needs to explain fast or replace the phones with a new phone. We all paid over $1000 this is not looking good for Apple.....

For what? With few exceptions the complaints here seem to be about battery capacity loss that is in line with Apple's specifications. On top of that the solution for battery issues is typically just a new battery, which Apple charges $79 for in the US for the iPhone X/11 models. How is a complete phone a justifiable request?

All rechargeable batteries lose capacity and can do so at varying rates for all sorts of reasons that can and can't easily be explained. For everyone who had a battery that lasted considerably longer than expectations there are many other others that had "normal" capacity loss. I wouldn't look at atypical performance to reflect what

Mine has been dropped down to 98% in just 1.5 month of use by only using an average screen time on of 3-4 hrs. I charge once everyday and use 70% battery daily before next charge. Is it something i should be worried on? Please advise. Also facing drain of battery while using my phone continuously like while checking emails and social media as well.

My issue is a little bit different. I bought my new iPhone 7 and after that an iPhone XS. Both phones maintained 100% battery capacity for 3 -4 months. However, after that they both dropped very fast. So how can the battery capacity drop 1% from 100-99 in 4 months and then drop another 1 or 2% just days or a week later? Makes no sense.

It’s normal. Maybe not typical, but within a reasonable range of performance. Batteries have manufacturing variations and some might have a little bit less capacity.

For Apple, the magic number is 80%. It’s like a tire warranty. Unless it’s down to the wear bars, the warranty terms don’t apply. In this case Apple won’t consider a replacement unless it’s under 80%.

I use what apple gave me the fast charger and it has so far from day one not changed off 100%

We're seeing normal variations, including some that (when interpolated into midway points) don't seem all that far off from Apple's specified battery performance of 80% after 500 cycles. I certainly don't sense that there's anything more than normal variations, with a few exceptions. Many of the complaints I see posted in this topic (including posts asking for a new device) on their face seem to be complaints that they're not vastly exceeding the performance that others have seen.

As for fast charging, that's been going on to some degree for a while. While iPhones only came with a 5W "cube" for years, many were using higher power adapters or via Macs (I believe up to 2100 mA for USB-A and now 2400 mA for USB-C) for years and not noticing any accelerated decline. When going over 80% and then approaching full charge, the power management system always reduces the charging current. This is absolutely needed to obtain as full a charge as possible and to prevent the battery from overheating.

Same here my friend. I bought my iphone 11 on 11th October, and now the battery health is 97%. I think it is absolutelly not normal. My 4 years old iphone 6 has 75% battery health. After that I feel like this phone’s health will be 10% when it gets to 4 years old. Shiiiiit

If your battery is at 75% on your iPhone 6 it needs to be replaced. Try this. Throughout the day check your battery health, right when you wake up, when you leave for work when you get to work, after resetting it, etc. I think you will find it will fluctuate. And the health definitely does not drop in a linear fashion. You have until October 10, 2020 to use your warranty, if your battery is down to 80% or lower by then get it replaced under your warranty. Otherwise stop obsessing about it.

i have an iPhone 11, and it’s gonna be two months this coming January 6. It already dropped to 98% even though i’m taking good care of it. I refrain from overcharging and stuff like that, but still 98% within a month and a half?!

Got my 11 pro on launch day. After 3 months of using it battery health is at 96%. This drain is abnormally fast compared to my 7 plus that lost 12% over almost 2 years of use and my iPhone X that dropped 2% after 8-9 months of use. I noticed my 11 pro was on 100% until I updated to 13.3 that’s when it started dropping. Hopefully this issue is addressed by Apple, I don’t think it’s any kind of glitch or inaccuracy, I think these phones have defective batteries. Lots of people have talked about it online and I haven’t seen any issues with people who have the regular 11

Mine is even worst. I had my Iphone 11 for only 24 days and the battery health is already at 99%. I don’t know if this is normal or I should go to the apple service center considering that some comments here are saying that apple will only replace iphones with 80% battery health. This is really stressing me out.

Call Apple support and ask them to do a remote diagnostic on your phone. This will tell you your battery charge cycle count. My battery charge cycle count was 171 and that resulted in a 98% battery capacity in about a 3-4 month period. After you get your battery charge cycle count, then you will know if your battery has a problem or not. If you have a Mac, you can download coconut battery and get the same info from that if you ae lazy to call Apple support.
