Individuals appear obsessive about the well being of their iPhone’s battery.
You possibly can see this info your self by going to Settings > Battery, and there is extra info when you click on on Battery Well being.
However I am right here to let you know that this quantity is junk. It is a feel-good quantity that does not actually let you know something significant in regards to the precise well being of your battery.
My iPhone tells me that my battery continues to be at 98% capability after months of use.
That is nonsense.
However your iPhone is aware of the reality. The iOS working system collects a whole lot of details about your battery and the general well being of your system.
However, as normal, Apple would not make it straightforward so that you can entry this info and has chosen to bury this info deep within the bowels of iOS.
To seek out this info, it’s a must to go to Settings > Privateness, then scroll to the underside and faucet on Analytics & Enhancements.
Then you could click on on Analytics Knowledge. This setting solely exists when you’ve got Share iPhone Analytics (or Share iPhone & Watch Analytics) enabled. If it is not enabled, you will must allow it and wait a day or so for the iPhone to gather the information.
Sure, the data is simply logged when you select to share it with Apple. However oddly, Apple would not make it straightforward so that you can take a look at it.
If Analytics Knowledge is enabled, then faucet on it, and you will be introduced with what seems like a wall of information.
Do not panic!
It is advisable to scroll till you discover a file beginning with the identify log-aggregated. There’s more likely to be a bunch of them with dates within the identify.
The newest one can be on the backside of the listing. Oh, however when you’ve got an Apple Watch paired with the iPhone, then there can be an identical file for that too. To inform the distinction, faucet on it to open up the file, scroll to the highest and search for it to say iPhone OS and never Watch OS.
And going by way of this information on the iPhone itself is a ache (though it may be completed when you’re affected person and do a replica and paste into an app like Notes).
What I do is I faucet the Share button and electronic mail the file to myself so I can open it at my leisure on a Mac or PC (you may at all times AirDrop it to your self).
The file comprises a whole lot of info, so after you have it open in a textual content editor, you can begin on the lookout for particular info.
Right here I am on the lookout for 4 particular entries:
These can be scattered in regards to the file, for I recommend doing a seek for BatteryCycleCount, design_capacity, nominal_charge_capacity, and raw_max_capacity.
Beneath these entries can be a quantity inside integer tags.
So, what do these numbers imply?
- BatteryCycleCount is the variety of recharge cycles the battery has gone by way of.
- design_capacity is the rated capability that Apple claims the battery to be, measured in mAh (milliamp hours).
- nominal_charge_capacity is the battery capability because it presently stands, measured in mAh (milliamp hours).
- MaximumFCC was the utmost capability of the present battery (virtually at all times, that is the primary cost capability), measured in mAh (milliamp hours).
Discover the discrepancy between the battery’s rated capability (design_capacity) and its precise capability when new (MaximumFCC).
That is a distinction of just about 200mAh.
Apple prints a rated capability on its batteries, however this can be a theoretical quantity, and the precise capability will fluctuate due to manufacturing variations.
However all of the batteries that Apple matches into iPhones could have a capability no smaller than the rated capability, and in fact, each one I’ve come throughout has a bigger capability.
That is why that Battery Well being quantity stays at 100% for thus lengthy and would not begin to lose tick down from day one.
And it is why that Battery Well being quantity is meaningless.
There is no manner that after 264 recharge cycles, my battery has solely misplaced 2% of its capability.
In keeping with Apple, the battery is rated to carry 80% of its capability after 500 full cost cycles.
Which means my iPhone is greater than 50% by way of that 500 cost cycles.
However is there something you do something to cut back battery put on?
The underside line is that your battery will put on, however you’ll be able to take steps to cut back on untimely put on.
As a part of regular sporting, your battery will lose about one proportion level for each 25 cycles (be aware that you simply may not begin noticing this instantly as a result of the precise capability or MaximumFCC of the battery is bigger than the rated capability). That is simply physics, and aside from utilizing your iPhone much less, there’s not a lot you are able to do about it.
So my battery has misplaced about 10% of its capability.
You possibly can’t change the legal guidelines of physics.
Nevertheless, you’ll be able to scale back untimely battery put on by retaining the battery inside its rated temperature zone and never overcharging it.
The iOS characteristic referred to as Optimized Battery Charging does an excellent job of stopping untimely battery put on from overcharging.
However be aware that every one you’re doing is lowering on untimely battery put on.
It would not do something for normal battery put on. Your battery will put on out, so take pleasure in it whereas it really works, and both plan on getting it changed or changing your iPhone.
And cease obsessing over that Battery Well being quantity!
