iPhone XS Smart Battery Case improving Battery health?

[Thai]

The weirdest thing...when i got battery case, my battery health on XS was 99%.

Now, it is 100% after using battery case for 5 days. I am BETA software 12.2. Is this Beta doing it or battery case made my battery better???

It's an estimate. It has the ability to fluctuate daily within a few % points. The case isn't making your battery better.

As Noobinator stated, it’s an estimated amount. Even conditions can make it fluctuate, such as temperature.

Pro tip: stop paying attention to it and just enjoy the device.

I am paying attention more now just out of curiosity since getting the Smart Case.......want to make sure that it does not hurt internal battery! Just surprised that it went UP. Never had that happen to me BC (before case).

It’s designed to work effectively with the iPhone and to charge in a healthy fashion, just as a wall outlet would. You’re safe to use it without worry.
