iPhone Battery Life Test

Are you experiencing a performance issue or slow speed on iPhone?  Apple confirmed that the iOS would throttle the performance of iPhones with an older battery. This makes sense, and you can speed up iPhone and get the performance back by replacing the old battery. In addition to this worn iPhone battery, there may have other reasons that may affect your iPhone performance, and the main reason is lack of free space.

Before you start to replace iPhone battery, make sure the iPhone required a new battery. The battery test on iPhone can give you an exact figure of iPhone battery wear level. Remaining battery life, some battery cycles run, the full charge capacity of iPhone battery, etc. Here, we are going to present you three best solutions to check iPhone battery.

iPhone Battery Check App

The easy answer is to install a proper battery check app from iTunes Store. We checked on Battery Life test app that is available for free on iTunes. This app can display approximate run time of iPhone while using 3G, Video Playing, etc. However, for a battery life test, we will be interested to know more about battery life cycle, total capacity available on the battery to charge, etc.

This app is good at calculating the raw data, monitor iPhone runtime, etc. in the Raw Data screen; the app shows the total capacity of the battery and iPhone battery charge capacity. However, this app is not showing the complete life cycle of the iPhone battery that runs in the entire life of iPhone.

Those who want to try a different iPhone battery app, we listed an alternative app. Both of these battery apps can provide the information about battery capacity, charge level etc.

iPhone Battery Check on Mac

Coconut Battery is one my favorite app to check the battery life of iPhone and Mac. This battery test app is coming as entirely free to use for Mac platform. This app is useful to show you lot of information about the iPhone battery and different from iPhone battery apps available on iTunes.

There is no dedicated iOS app from CoconutBattery team; you have to rely on Mac app to check the battery of iPhone. First, download and run the coconut Battery app on Mac to test the Mac battery. To check iPhone battery, you have to connect iPhone to Mac with the lightning cable. After connecting the iPhone to Mac with the cable, click on iOS device menu on the Mac CoconutBattery App. You can see a bunch of useful information about your iPhone on the screen.

This includes full charge capacity and design capacity of iPhone battery. I tested iPhone 6 with the coconutBattery app, and my whole charge capacity was around 200mAh less than design capacity. And one more interesting factor is the cycle count that is showing as 979. As you can see the manufacture year is 2014, and I used this iPhone for three years. During the period I used to charge every night and discharge the phone in the daytime. This makes sense that my iPhone battery went through more than 950 charge-discharge cycles throughout this three years period. At this point, my iPhone is not supporting a full-day battery life and time to replace my battery.

iPhone Battery Check on Windows

Coconut battery app is not supporting Windows users, and there is a similar tool for Windows users to check iPhone battery. The app is developed by CopyBot and offering the same functions to tets iPhone battery with Windows. You have to install the CopyBot app from the link give below and connect iPhone with a lightning cable to Windows PC. After you connect the iPhone to Windows machine, launch the program iBackupBoat on Windows. This will display the connected iPhone on the app sidebar.

Apple has published a detailed article about Lithium-ion battery and how to maintain battery on Apple devices. You can replace your old iPhone battery from Apple’s authorized service centers or Apple Store Genius Bar (3-5 days). Apple is also offering an online program to replace iPhone battery at the cost of $79.00 ($29.00 discounted price) for eligible iPhone models. Please go to this Apple battery replacement page for more details and to initiate an iPhone battery repair.

There is no need to replace iPhone battery if you are happy with the battery life of iPhone. Also, anything under 600 of iPhone battery cycle count is good to go, and you can get a pretty good battery performance with the current one. The higher difference in designed capacity and full charge capacity is showing the lack of iPhone battery to hold the charge at total charge level. Based on these facts, if you can get a performance increase of 30% or more, go ahead and spend 79 bucks on iPhone, that can extend your iPhone life for another three years.
