An iPhone battery usually lasts throughout a full workday, but rarely much more than a day, which means that you still need to do the ritual of nightly recharging. Also, just like on most Apple devices, the battery inside iPhones is a Lithium-Ion (Li-Ion) one, meaning that it degrades after time.
With recent iPhone performance slow-down reports linking CPU performance to battery health, you might want to know one crucial detail about the battery: how used is it exactly?
Battery age is measured in battery cycles, where one cycle is equal to the process of draining and completely filling up the battery once. This can mean that you use up your battery from 100% until the phone is at 0%, or completely dead, or you can drain 55% of that battery one day and 45% the next day, and together, the two days combine for one, complete 100% battery cycle.
Now that we know how you get 1 battery cycle count, we need to know how many cycles can an iPhone battery go through before its capacity deteriorates significantly. Apple's official support page gives the following Li-Ion battery longevity for different products.
How long is a battery supposed to last?
- iPhone - 500 cycles
- Apple Watch - 1,000 cycles
- iPad - 1,000 cycles
- iPod - 400 cycles
- Macbook - 1,000 cycles
Typically it would take about two years - but it could be more or less depending on individual usage - to get to that critical number. When you hit that limit, this means that the Li-Ion battery has degraded to 80% of its full capacity.
So how do you check how many battery cycles is your iPhone battery on? Apple has blocked apps reporting battery cycle count on the App Store, so you will need to your iPhone, a Lightning cable and a desktop computer to check
. While there may be other solutions, we use iBackupBot, an app available for both Windows and Mac as a free 7-day trial and paid after that. We walk you through the process of setting it up and learning about your iPhone battery cycle count right below.
How to check how many battery cycle clocks is your Apple iPhone on
1. We need to download a third-party app for this!
Go to www.icopybot.com, and select the Download tab. There, pick iBackupBot and select the version for your machine: Windows or Mac. Install the program.
2. Open the iPhone listed under Devices (1. arrow)
You should see a picture of an iPhone with various options on the right panel. Click on the 'More Information' (2. arrow)
3. And you have all the info right here!
We have an almost brand new iPhone XS Max that is just on 21 cycles. Since the battery on iPhones is rated for 500 cycles, it should still be in great battery health for the next few years!
4. Starting with iOS 11.3, you might skip this step
iOS 11.3 brought us a brand new Battery Health menu in iPhone settings. Apple still does not show the full cycle count there, but it gives you a percentage number. If your battery health percentage is more than 80%, then it's in good health, but if it falls below 80%, that means it's time to think about replacing the battery with a new one.
5. And that's it!
You've just finished our quick crash course on how to check the battery health on your iPhone!
