How to Check iPhone Battery Health with Best iPhone Battery Checker

Last Updated: Jan 11, 2018

With increasingly more iPhone battery problems emerging every year, from overheating, draining, to swelling which bulges the screen, we iPhone users become more and more concerned with our iPhone battery health and safety. To get weekly informed of the iPhone battery diagnostic and check iPhone battery health regularly can help us detect problems in time and take action in advance - reporting problems to Apple, having a battery replacement or an iPhone 6/7 trade-up.

For new iPhone X/8 users, you should frequently check iPhone 8/X battery health for at least once a week especially when your warranty is about to expire!
Also, if you're covered under AppleCare+, check your iPhone battery health to know when to replace the battery at no charge if it's less than 80 percent of new.

Even if your iPhone is out of warranty or out of AppleCare+, Apple is now offering $29 battery replacements for every "iPhone 6 or later" iPhone model through December 31, 2018, meaning they have cut the price of a replacement for an out-of-warranty battery to $29 from $79 for an iPhone 6 or later. You should be happier than ever to frequently check you iPhone battery health and start a battery service request when needed. However, at present, the official supplies are extremely limited.

What are the criteria that determine a healthy iPhone battery?

1. iPhone cycles: technically speaking, when your iPhone cycle reaches to 800, meaning you have charged your iPhone for 800 times, your iPhone battery is somehow aged. And it is typical that your current iPhone might have been used for 3 years.

2. iPhone wear level: technically, when the iPhone wear level reaches at 25% (85% of new), the iPhone battery should be changed to a replacement.

3. iPhone battery capacity: this data has two functions. A. calculate the wear level by yourself in case you do not trust the auto calculator; B. compare the battery replacement with the original one and see whether it is detected with the same capacity (as good) as the previous one.

Therefore, if your current iPhone 6 battery has a charging cycle of 800 with a wear level at 25%, bet you might have been using it for about 3 yrs, and it's time to think about getting a new iPhone battery replacement.

How to Check iPhone Battery Health?

There are mainly 5 iPhone battery health levels offered by DearMob iPhone Manager: Perfect, Good, Bad, Very Bad, and Almost Die.

Check iPhone 6 Battery Health Bad

These battery health notifications is in pair with the iPhone wear level:

0% - Perfect (100% of new)

1-10% Good (90-99% of new)

11-20% Bad (80-89% of new)

21-30% Very Bad (70-79% of new)

Above 31% - Almost die(below 70% of new)

Of course, you don't necessarily have to get an iPhone battery replacement immediately when the battery health score goes to "Bad" or "Very Bad". The gradings here merely present technical suggestions on when to change an iPhone battery rather than "you should change it right now or it will get exploded". Generally, the battery scoring "bad/very bad" can sustain another 2-3 years of nearly sufficient battery supply, while for iPhones with battery health at "Very Bad" level might have to resort to more frequent charging in case of iPhone battery draining super fast.
