Ready for an iPhone Battery Replacement, How to Check?

Are you experiencing a performance issue or slow speed on iPhone?  How do you check it’s the time for iPhone battery replacement? Apple confirmed that iOS would throttle the performance based on iPhone battery life. This makes sense, and you can speed up the iPhone and get the iPhone performance back by replacing the old battery.

Before you go for iPhone 6 battery replacement, make sure the iPhone required a new battery. The battery test on the iPhone can give you an exact figure of iPhone battery wear level. Remaining battery life, total 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 life.

Check iPhone Battery with Third-party App

The easy answer is to install a proper battery check app from the iTunes Store. We checked on Battery Life test app that is available for free on iTunes. This app can display the 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 the 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 the iPhone.

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.
