Apple actually wants to vary the best way it shows battery put on in iOS, as the present methodology is inflicting confusion amongst iPhone homeowners. Every time there’s an iOS launch — both a giant one or a small safety replace — each my social media and my inboxes grow to be awash with folks worrying about their iPhone’s battery.
Undecided what I imply? Let me convey you in control.
Additionally: This is what Apple would not need you to find out about your iPhone’s battery
Seize your iPhone, faucet on Settings, and head over to Battery after which Battery Well being & Charging.
Right here you may discover a Most Capability quantity.
That quantity begins out at 100%, and slowly ticks down as you cost and discharge your iPhone.
The one quantity that has precipitated a lot confusion amongst iPhone homeowners — Most Capability. Adrian Kingsley-Hughes/ZDNET
If you wish to geek out about what this quantity means or know extra about your battery, I’ve written about that intimately.
The misconceptions
What I wish to do right here is evident up some misconceptions surrounding this quantity.
1. This is only one measure of battery put on
Most Capability quantity just isn’t a measure of total battery put on. As a substitute, it’s “a measure of battery capability relative to when it was new.” Put that one other means, it is how a lot energy the battery can maintain.
Additionally: iPhone 15 may very well be getting a giant battery increase, and it actually wants it
The decrease the capability, the much less utilization you are going to get between prices.
Nevertheless it’s a poor measure of the well being of the battery. I’ve seen batteries die whereas this quantity is within the 90% vary, and I’ve additionally seen iPhones plod on with this quantity down within the 70% zone.
2. iOS updates aren’t inflicting battery put on
Updates do not put on your battery. What does is the conventional charging and discharging of the battery as a part of utilizing the iPhone, subjecting the battery to overheating, and, far much less generally, utilizing poor high quality chargers and cables.
Doing issues like retaining your iPhone on cost on a regular basis or by no means letting it absolutely cost may also generally trigger the Most Capability determine to show an misguided worth, and I’ve additionally seen it soar about following an replace. However this is not inflicting put on. As a substitute, it is inflicting iOS to show an incorrect quantity.
3. Hitting 80% just isn’t dying to your battery
I believe it is a frequent false impression that arises from Apple’s personal documentation.
Apple has revealed details about recharge cycles and the way they have an effect on batteries, and right here it says that the iPhone’s battery “is designed to retain as much as 80% of its authentic capability at 500 full cost cycles.”
Additionally: This highly effective app tells you about your iPhone, iPad, or MacBook’s battery
I believe that this gives the look that the battery is lifeless at that time.
Whereas the battery is undoubtedly worn, and if you happen to obtained 10 hours out of a cost when the iPhone was new, you are now getting eight hours. This may not be an issue for you, and the battery may offer you many months of use.
So, what’s the issue right here?
There are two issues at play right here.
1. The Most Capability proportion is pointless
I get that Apple was maybe attempting to be useful right here, or possibly simply filling house on a display screen within the Settings app.
Both means, that is only a single quantity and never a measure of common battery well being. Apple would do higher to eradicate this quantity and change it with one thing extra significant, like recharge cycles. Apple may additionally provide you with a greater approach to painting battery well being.

For reference, this quantity continues to be current within the present iOS 17 betas.
2. Most Capability is highlighting an issue with fashionable iPhones
And that’s that they want a whole lot of recharging. Gone are the times of getting days out of a cost.
Or, to show that on its head, batteries are too small for the demand we’re placing on them.
For those who’re just about absolutely discharging your iPhone every day, then 500 recharge cycles are going to take you round a yr and 4 months. For those who’re utilizing about 50% of your battery’s capability every day, then 500 prices are going to take you about three years.
Additionally: The perfect MagSafe battery packs
What I am seeing, each in my utilization and within the utilization of others, is that there are lots of people who’re barely making it via a day on a single cost, and as such, are going via these 500 recharge cycles inside two years.
The options
There are three options to this — it is advisable use your iPhone much less, Apple must equip it with an even bigger battery, or battery replacements must grow to be part of iPhone possession (and Android smartphone possession, as a result of the batteries in these units put on in the identical means).
That is it.
You possibly can’t, regardless of the infinite stream of weblog posts and YouTube movies, hold your battery’s Most Capability determine at 100% it doesn’t matter what you do. Even if you happen to hold it in its field within the drawer.
Finally, that battery goes to put on.
Additionally: Your iPhone battery is mendacity to you in bizarre methods
The perfect resolution can be for Apple to engineer a battery that is straightforward for homeowners to interchange — you recognize, like devices used to have. Till we get that, battery put on goes to proceed to be a problem and homeowners are going to must have to interchange it or purchase a brand new handset.
As a result of one factor’s for certain: You possibly can’t change the legal guidelines of physics.
