Iphone x battery max capacity

Sounds pretty normal to me. There are a lot of little variables. One of them is that there might be a standard deviation for original capacity due to manufacturing variations.

Apple rates the battery at 500 complete charge-discharge cycles before a typical reduction in battery health to 80%. So if it's an average 250 cycles per year, a linear degradation would be expected to mean a reduction to 90% in one year. 99% doesn't sound like there's a problem.

Also - it's important to understand that the battery health number is just an estimate.

A lithium battery begins to loose capacity the moment it is assembled at the factory. It will continue to steadily lose capacity throughout its useful lifespan, and whether used or not - the decline is an inherent chemical degradation process and cannot be stopped, paused nor reversed.

So from the day you bought your lithium powered device (be it an iPhone, a laptop, an electric toothbrush or whatever) the battery has been steadily losing capacity since the day it was made, and will never truly be at 100% ever again.

And as mentioned several times in this and other threads, the level shown is an estimation - it is not exact, nor even all that precise. There is no algorithm based on measures current, voltage and resistance that can precisely determine any battery’s true electrical charge capacity. The estimated capacity will also fluctuate over time as loads on the battery vary.

I wouldn't worry about it. There are several possibilities. Manufacturing variations may affect capacity. Some manufacturers provide a minimum vs typical capacity for a new battery. Sometimes it might even come up at more than 100%. There are other reasons why there might be less than 100% new. Also - it's really just an estimate. Some users report that the battery health can go up.

I also wouldn't worry about using the iPad power adapter. I use a 12W iPad power adapter myself as well as a Mac notebook computer. Those all charge at the maximum 2100 mA. Yours should be able to provide 2000 mA. It certainly charges faster - at least until the charging circuits reduce the charging rate. It might result in a little bit more heat (which degrades the battery faster) being generated compared to using a 5W power adapter. However, that's a tradeoff for convenience. It's up to you if the convenience is more important than a tiny loss of capacity.

In the end it's easy enough to just get a battery replacement service. Some users try to get their batteries to last the life of the device. Others just replace the battery.

Hi there!

This is normal - regular use of your iPhone leads to the battery capacity shrinking... having 99% max capacity is good!

Hope this clears things up,

The max capacity reading will fluctuate, especially during the first few months of use. Tomorrow it may read 100% or 102% or 98%.

Hi

The issue is known

Apple has changed my phone by a new one because of this

Please contact Apple support and ask for replacement

Good lu

Hi,

In iOS 11.3 Apple introduce a new feature "Battery Health" that measure the battery capacity relative to when it was new. If you are running iOS 11.3 or later then go to Settings > Battery > Battery Health.

See the following link https://www.trickyways.com/2018/02/check-iphone-battery-health-capacity/ to know more about how to check iPhone battery health and what is the total battery capacity of all the iPhone and iPad models.

hi... i also have same problem... i just bought ip7+ bout 15 days ago... as i talk with apple cust care, she told me

99% good as 100%. 1% wont hurt. the factor max capacity drop is cause from our using habit.

It’s completely normal until it goes below 85, mine went to 98 in one month but I restored it and it increased to 99 . Follow this :

https://www.apple.com/batteries/maximizing-performance/

You should back up everything on iCloud and factory resetting it and I was at 95 and I was like I am going to factory reset it and I did that it went up to 98.

Have you not read the comments above? They do refer to your problem as well as that of the person who started the thread. You have nothing to worry about.

If you have another concern, start a new thread so that answers will relate only to you.

Hello,

I have the same issue, I think it's related to the iOS 11.3 as before all was ok even the external apps on apple store was show 100% but since I set the iOS 11.3

I have this issue

also I reset my phone the battery comes up to 100 % for 3 days

and when my phone restart it becomes again to 99 %

there is something wrong with the IOS

however I check my phone on the MacBook console and the battery health was 100 % with 132 full cycle

I think no need to worry

and wait for IOS 11.4

to find out if all will become good again or not

forget to tell I contact apple store in Brussels and apple support no one know anything about this

all says it's normal and if you want to change the battery we can do it for free

It also depends on your management of battery, if you follow Apple battery usage guide to maximise battery life so your battery capacity will not drop but can increase too.

If worst comes to worst you can always take it in to your local apple store for check up and bought mine off mate it’s 98% he’s used it som

Please update the ios

And check the full cycles of the battery charge using the coconut app

And tell me so i can help you
