This is what Apple does not need you to find out about your iPhone’s battery

Apple provides you entry to very particular details about your battery. You may see this your self by going to Settings > Battery, and there is extra data if you happen to click on on Battery Well being.

However your iPhone collects much more details about your battery.

Much more.

However Apple does not make it simple so that you can entry this data.

It is buried. It is buried deep.

To search out this data you need to go to Settings > Privateness, then scroll to the underside and faucet on Analytics & Enhancements.

Then it’s essential to click on on Analytics Information. This setting solely exists you probably have Share iPhone Analytics (or Share iPhone & Watch Analytics) enabled. If it isn’t enabled, you may must allow it and wait a day or so for the iPhone to gather the info.

Sure, the knowledge is barely logged if you happen to select to share it with Apple. However oddly, Apple does not make it simple for you to check out it.

If Analytics Information is enabled, then faucet on it, and you will be introduced by what appears to be like like a wall of information.


Analytics Information

Do not panic!

It’s essential scroll till you discover a file beginning with the title log-aggregated. There’s more likely to be a bunch of them with dates within the title.

The most recent one can be on the backside of the checklist.

Faucet on it to open it and it will be full of data.

A ton of it.

And going via this knowledge on the iPhone itself is a ache (though may be executed if you happen to’re affected person and do a replica and paste into an app like Notes).

What I do is I faucet the Share button and e-mail the file to myself so I can open it at my leisure on a Mac or PC (you can all the time AirDrop it to your self).

The file accommodates quite a lot of data, so upon getting it open in a textual content editor you can begin on the lookout for particular data.

First off, if you happen to search for BatteryCycleCount, that can let you know what number of recharge cycles your battery has been via. In keeping with Apple, your battery ought to retain 80 % of its capability after 500 recharge cycles, so gaining access to this determine.

That is in all probability an important determine that Apple does not let you know.

However there’s extra.

One other metric is MaximumFCC, which refers back to the most capability of your battery when new as measured in mAH (milliAmpHour). Apple prints a rated capability on its batteries, however it is a theoretical quantity, and the precise capability will differ.

The determine that you just get from the log file would be the most capability of your battery as measured by the iPhone.

The MaximumFCC will virtually all the time be a couple of % better than the battery’s rated capability. This accounts for why the battery does not begin to lose Battery Well being on day one.

One other determine you will get out of the logs is NominalChargeCapacity, which supplies you present capability of your iPhone’s battery. That is the present capability of your iPhone’s battery and is once more measured in mAH.

This offers a sign of how worn the battery is.

Are you able to do something to cut back battery put on?

Probably not.

Your battery will lose about one share level for each 25 cycles (notice that you just won’t begin noticing this instantly as a result of the precise capability or MaximumFCC of the battery is bigger than the rated capability), then aside from utilizing your iPhone much less, there’s not a lot you are able to do.

You may, nevertheless, cut back on untimely battery put on by holding the battery inside its rated temperature zone, and never overcharging it.

The iOS function known as Optimized Battery Charging does a superb job of stopping untimely battery put on from overcharging.

However notice that I mentioned, “untimely battery put on.”

It does not do something for normal battery put on. You may’t change the legal guidelines of physics.
