Here’s How To Check The Battery Health Of Your iPhone, Reliably And For Free

The free coconutBattery application for Macintosh, shows the battery health of your iOS device (iPhone, iPad and iPod touch).

Apple made billions in hiding the fact that it was slowing down the performance of an iPhone with an aging battery, pushing people to buy a new phone rather than a new battery.

Worse, the technology giant only admitted the existence of its secret power management “feature” in iOS to avoid phones “sudden shutdowns” only after being caught red-handed by performance benchmark tool Geekbench last December.

More than a month later, Apple has still not released the iOS 11.3 software update that will let iPhone owners switch off the “battery saver” feature that is affecting the iPhone 6, 6 Plus, SE, 6S, 6S Plus, 7 and 7 Plus.

The tech juggernaut, that just had the best iPhone year ever in 2017, also promised that the update will show the phone’s battery health and a recommendation to whether the battery needs to be replaced. However, in the meantime, Apple is still banning battery-health apps from the App Store for security reason . Go figure!

There’s hope, though. Mac developer Chris Sinai released a free application, coconutBattery, that measures the current health of your Mac’s internal battery as well as any iOS devices (iPhone, iPad and iPod touch) attached to it.

It shows your battery’s current charge level, its full charge capacity and most importantly its design capacity, which is the original capacity your battery had when it left the factory.

Apple officially calls a battery “bad” when its health falls below 80% within the first 1000 charge cycles. In our tests, the batteries on the iPhone 5 (28.8%) and 6S (76.6%) need to be replaced whereas the 2-year old 6S Plus is right on the edge (80.8%) and the brand new iPhone X is already down a notch (99.5%).

Sinai’s battery application also offers other interesting pieces of information like the age of your battery, the cycle count (how often was your battery loaded from 0% to 100%) which should be kept low to increase your battery life, as well as the temperature inside your battery.
