iPhone X Battery health went from 89% to 82% with iOS 13.3

Did any of you experience something similar or should I visit an Apple reseller?

Are you using fast or wireless charging?

No, the default charger that comes with the iPhone X.

It's been over two years since the iPhone X was launched. If you bought it during the launch period, the battery is due for a replacement.

Sorry, my English isn’t the best, so just to be clear:

I meant to say that the battery health went down 7% since updating to iOS 13.3. So during 2 to 3 weeks, the battery health went down from 89% to 82%.

I bought it in February 2018.

Sounds like it's due for a replacement. The battery lasts about 500 cycles or about 12-18 months, depending on usage.

Updating is one of the most stressful loads applied to a battery and the drop in capacity you experienced is just a coincidence and had nothing to due with he update. The update was just a trigger and shows that your battery can't handle heavy loads placed on it and should be replaced..

The battery health didn't change. What changed is the battery health app displayed value.

Your battery health was re-calculated with the update. It didn't actually drop 7% at once. That's likely what it was really at before the update, and you're just getting a more accurate measurement now.

But remember, battery health is always just an estimate.

That's true in theory, but I've used iPhones that were 3 or 4 years old on their original batteries that still offered sufficient battery life and performance. In fact, I've never had any device's battery fail in just 18 months. Battery wear is a science, but certainly not an exact one. I think that the best thing that users can do is not think about counting cycles, years, or checking the health, just use the device until/unless it becomes a problem.

If the primary use of your iPhone is checking battery health percentage numbers you will have issues.

Consider never checking your battery health percentage ever again unless and until you experience a shut down mid day after a full overnight charge.

It will be as hard to stop checking battery health as giving up crack cocaine, but it can be done. 👍
