So you've been using iOS 13 for a little while and noticed your iPhone is pretty slow to charge. Using the 5-watt power adapter out of the box, in the time it used to take your iPhone to charge its battery to 100 percent, your iPhone is stuck at 80% or below instead. That's because Apple introduced a new feature in iOS 13 that slows down charging — but for a good reason.
The battery icon in your iPhone's status bar gives you a visual idea of how much power is left, and there's a battery percentage option you can switch to or view in the Control Center, depending on your model. But what you may not know is that there's a way to view the battery percentage of every device connected to your iPhone, from AirPods to Bluetooth speakers and your Apple Watch.
I don't know about you, but nothing is more annoying than when my phone hits 15% and I'm nowhere near a charger.

Well, with Android 9.0 Pie, we finally can escape this.

But that doesn't mean it's gone entirely.
