How to check your iPhone battery cycle count the super easy way

Previously, checking how many cycles you have gone through on your iPhone's sealed battery involved either jailbreaking, or installing a computer program to display the cycle count. There will be a tidal wave of upgrades to the iPhone 7 this year, tip analysts, as there have never been so many iPhones that are two years or older than we will have in September, and a bunch of the oldies will hit the used phones market.

Thus, knowing how much cycles are left in the battery of the second hand iPhone you are already salivating over, becomes one of the crucial tests to run before you purchase. The good quality lithium batteries, of the type that is in iPhones, last about 500 cycles in ideal circumstances (full top up, stock charger, no overheating), before starting to degrade. Given that most owners charge their iPhone almost every day, a two-year old one may just be on the cusp, so checking the number of charging cycles it has been through quickly before you buy it will come in handy. Here's what you need to do:

1. Download Battery Percentage off the App Store;

2. Start the app, and check the charge cycles that the iPhone or iPad has been through already;

3. The Battery Percentage app will show other vital information about the juicer, like the battery health level (or degradation level) in percentages, as well as its charge level status. That's all - no jailbreaking, no hooking up to a computer to check the battery cycles.

How do you know it's not accurate?

Been using it since last week. I've seen inconsistencies with the cycles.

They ask permission to access your photos library to provide you with information like how much space you have lift for pictures and videos and how much space you have already used up. I just said No.

Photos storage space. Give it access and it'll tell you how many photos and how much space they're taking up. Turn it off and it just says 0.

You can just choose "do not allow" for that particular access. If you change your mind you can always "allow" it later..

Nope. If you do1 charging a day in one year you'll have 365 cycles. So you do more than 1 a day. I have 158

did this app get pulled? not seeing it

The jerks at Apple probably pulled it because I don't see it either, Apple pulls anything that they didn't think of or thats helpful to the user.

A friend retweeted an article that referenced this article, and I downloaded and installed the app on both my iPhone 6s and iPad Air. It seemed to work at first, but I then, within a day, wasn't able to charge either of my devices, and upon shutting down the device (in hopes that it was a temporary bug and a power cycle would fix it) now find that neither device will start up properly. So, I think the app was pulled for either being badly written, or malware, or both.

As it turns out, the cause of my damage was a crappy MOTA charger Plus, if you now search for the app, you'll now find it in the App Store. I'd post links but this system seems to not want n00bs to do so.
