My iPhone 13 Pro’s Battery Capacity After 8½ Months of Regular Usage

Three years ago, I had no idea what Chargie was going to become – world’s #1 phone battery protection system. I knew the basic principles of charge limiting and the positive outcomes it has on battery health, but at that point in 2019 they were only theoretical, or based on what others had studied.

Now, there are over 27,000 Chargie devices out there and countless testimonials of people using it and telling us (publicly or over email) how Chargie had changed the entire course of their battery life and how it saved them money, time and effort.

I’ve been personally checking my own iPhone 13’s battery every couple of days to catch any degradation occurring. I bought it new on Nov. 2nd, 2021 – about 8½ months ago.

Here’s a short screen recording I did today to show you my phone’s battery health. I did a movie so that there’s no doubt – you can see the warranty expiry date in the About screen (one year from the purchase date) and then the current battery health under Battery.

Of course, results may vary, but I’d be curious what your own iPhone’s health is right now. Many of you may have the same results because you happened to charge it often and properly without a Chargie, yes, it can happen. Still I’m pretty amazed by the rock-solid 100% after all this time, while a test iPhone 12 that hasn’t been used with a Chargie device since Nov. 2nd, is now at some 88% health. It had 99% health when I handed it over and had been religiously charged on a Chargie as well since November 2020.

The iPhone 13 Pro has been charged to 80-90% daily on a Chargie C Basic and a Chargie A. I used the Charge Scheduler to limit the overnight battery level at 50% and avoided fast charging when possible during the day. I also avoided deep discharging the battery (<10%). The phone’s motherboard has been replaced a month ago on warranty (bad signal), but that didn’t affect anything related to the battery.

I’ll write another post like this when battery health drops to 99%.

So if your phone’s (Android or iOS) battery is showing wear, or better, if you have a new one, my advice is to start using a Chargie – you’ll prolong battery life and improve your overall experience with it. You’ll forget about the initial Chargie investment, but will never forget the great experience that follows.
