A Follow Up To My Story On Optimized Battery Charging

When I last wrote about optimized battery charging in iOS 13, I explained how the feature works in theory and my observations about the feature. At the time, I noted the behavior that I was seeing and the fact that the feature had not turned on for me yet. A couple of days ago, I noted this:


If you look at the charge pattern, it charged to 80% between 10PM and midnight. It stayed that way until about 3AM when it started charging to 100% which ended at just around 5AM roughly. So at that point, the phone was ready to go for when I woke up at 6AM. I also noted that it doesn’t always do this. For example, today I woke up to find that it did normal charging and not optimized charging. So I am assuming that this is still a work in progress.

Another data point is that I have been observing my wife’s iPhone XR to see if I see similar behaviors to my iPhone XS. As I type this, even though the feature is turned on, it has made no attempt since iOS 13 has been installed to do any sort of optimized charging. That’s weird. It would be nice if Apple provided better documentation on how this feature worked so that there’s way less guesswork on my part. But all Apple provides is this document on the feature which really doesn’t help to explain the behaviors that I am seeing.

I will continue to monitor this and provide my observations on this feature.
