iPhone 11 Is this normal: Battery Health Still 100%

[murad_fourth]

Yes, it is very normal. As stated by other users in this thread, coconutBattery can help you get a much clearer picture on your battery. Some batteries come >100% design capacity out of factory, I’ve had some at 108%. Battery wear is not like water dripping out of a cup consistently over time... Battery University has a great book on batteries - states that even in the first hundred cycles your battery capacity for Lithium Ion can actually increase.

Most of my phones have been within 5% of design capacity after nearly 2 years of use (~250 cycles). My wife, a much heavier user of her devices than I am, usually has 150-200 more cycles than I do and about 8% capacity loss over the same time, though surprisingly, similar to my own battery that I no longer wear about “wear and tear” and just use my device as I want.

Keep the phone out of high heat situations, try to keep it >20% charge, you should be good.

Russell_314 is right - stressing over these things can really hamper one’s enjoyment of the device. First thing I do on all my iPads and iPhones is get rid of the battery % reader on the top right. It’s done wonders for me.

That’s exactly what was i doing before it dropped to 99% the day after i opened this thread.

I keep the phone out of high heat situations and try to keep it >20%.

Btw i want to let everyone know that, using AR to see an iPhone on Apple’s official website causes sudden high heat on a iPhone’s battery and fast drop in charge per cent.

I therefore don’t recommend iPhone users to try that. It may significantly affect your iPhone’s battery health.

It's completely normal. Below is the battery health of the X I purchased over a year ago. It's currently at 190 cycles and still at 100% per Coconut Battery.

 

[Tsepz]

Oh my god. I don’t believe it. Today i checked again when i woke up and saw that it is now 99%.

How is that possible?

I am dying of laughing now.

Here is the screenshot:

Last night it was 100%.

Just like I said, this can drop at anytime but it is an estimate, don’t focus too much on it if your phone is giving your sufficient battery life.

Apple should honestly remove access to this number and only make it accessible when the phone needs a new battery or when the phone drops below 90%. The moment it hits 89% then Apple should make it that the phone starts showing battery health.

I’m still at 100% on my XS Max after four months 👍🏻
Edit:

Certified pre owned XS Max

 

[AZhappyjack]

No. It works perfectly and this is the reason makes me worry about it. It should have already dropped to 99% or under until now, i think.

But if you think, it is perfectly normal, then it is fine for me.

May i ask, when did you buy your iPhone? Because your iPhone’s battery health is also 100%.

For what it's worth, I have an iPhone XS Max that I purchased on launch day (September 21, 2018) that is still showing battery health at 98%. So, yes, it's possible that your iPhone 11 is still at 100% after 7 months of use.

Lithium batteries will degrade just by aging alone, even if you never use the battery. I doubt that any lithium battery would still have its original capacity as installed after that length of time. Software interpretations of battery capacity are just an estimate. You shouldn't fret about several percentage points either way.

I see.

So after 1 year and 8 months of use, your battery health dropped by 2% only which is great.

Exactly this, but it seems people don’t want to listen at all

The Facebook iPhone groups are also filled with these sort of topics.

Apple need to hide this thing ASAP, it’s got people fretting over a stupid number.

 

[Motionblurrr]

While I agree that maybe hiding this number and keeping it only available to the Apple diagnostic tool would be a better idea (especially for me XD ), I think having a higher battery health percentage is attractive when it comes to selling the iPhone later.

That and or if you plan on keeping the phone for a few years and might be in a pinch financially, it's ideal to keep the iPhone battery as high capacity as possible.

I know someone with an iPhone 6 Plus with a 90% battery capacity at over 1,000 cycles 😂

 

[AZhappyjack]

Sure. I only checked it because I came upon this thread... the ONLY thing that matters is that it holds a charge... numbers are just a placebo... either it works or it doesn't...

 

[TimothyL]

Mine is still 100% and bought in September.
I think it’s great

 

[Shadowbech]

I use coconut battery app (I think you have to buy, not the free one, to get access to devices in addition to the Mac it runs on), and I am pretty sure it fluctuates some. I just checked, and note mine is showing a full charge capacity in excess of the design capacity of the phone.

It's actually free. But you need to have your device connected for readings. If you purchase a license, then you have the capability of it reading it wirelessly.

I got my 11 Pro Max on Launch day and still 100% and still the same full charge capacity it came with. Very happy with it.

 

[josecuervo888]

I don't know how accurate but mine is still at 100%.

 

[TheSkywalker77]

This post is honestly hilarious to me. As said above, don't worry about it! I wouldn't worry about my batter health dropping until it hits 85%. What's next? People complaining that their phone is too fast? Just enjoy your phone and don't worry about small things like that.

Actually i plan on upgrading my iPhone 11 to 5.4” iPhone 12 due to its dimensions. The dimensions of the iPhone 11 make it hard to use with one-hand.

Yeah if you're planning on upgrading to the new phone coming out in a few months then forget what your battery health is, it'll last you plenty long.

 

[robertosh]

My 6 is on 97%, replaced by Apple 2y2m ago. Basically the health will depend on your usage. My wife’s 6s plus, replaced same day, is 87%.

My XS bought on January 16th shows the battery capacity at 99%. I hate myself for looking, but I know I won't be able to resist looking again. Funny, because I'm the guy who tells everyone else to stop worrying about charging/battery issues and just use the phone.

The nice thing about coconut battery is it keeps a history. My iPhone 11 shipped with a battery 103% of specified capacity and actually went up to 105% until it began dropping off. Now at 18 months and 151 cycles it is still at 100%.

There you go. That’s why some are still 100% after a year or two and others drop faster. Depends on what you get from the factory. My 6+ was 108% design capacity. Yup.

 

[SegNerd]

It's not necessarily a problem, but I do know that I have had iPhones where the battery health stayed at 100% because I always kept it connected to either a charger or a battery pack - and it turns out this was actually a really bad idea. Eventually the battery swelled up and I had to have the phone replaced, even though it still said 100%.

 

[paulsonj72]

23 cycles for me in 5 weeks of use and battery is at 101.8%(rounded up to 102%)which is what the phone came with

This refurbished iPhone 12 Mini has been in my hands close to 20 months now and claims it's at 100% capacity. The alleged full charge capacity can explain this as it's 4 mAh above Design Capacity according to Coconut. But also notice Cycle Count is 0, which is ridiculous. I'd say this battery has been tampered with, so how can I trust any info given?

BTW, thw Current charge capacity graphic percentage is always off, about 10, from what Coconut shows.

This unit since 12 months or so displays power problems in that once charge goes down under 40%, it can die without warning. Typically it can start once again, but now charge is 10% and soon it dies completely. When recharged it's back to normal. When I started using it this unit could run down to under 10% without problems. Occasionally it still does, but this is rare. Why wouldn't this recent behavior be reflected in the Coconut analysis? Probably because the battery somehow manages to lie about its state.

Except for dying on me when I cannot charge it, it has some volume issues, that may or may not be related to power issues. Otherwise will work fine, as long as I keep the charge topped to 40-80%.

Coconut is basically a random number generator, don't trust that for anything. Coconut's the one tampering not your battery.

What you're describing is a voltage issue though which has nothing to do with charge capacity but does mean that your battery needs to be replaced.

 

[MikB]

With? The Cycle count is also visible as 0 in other tools like iMazing. Actually iMazing (unpaid version) has more data than Coconut and is not off on current charge, though here I learn that Battery Current Charge may not be what I thought as those are different values (76.2 vs 80). iMazing is wireless as I've paired it.

Why shouldn't we trust info that the device itself would seem to be source of?

A voltage issue that discharges the battery from around 40% to 10% in seconds?
