Your AirPods Pro can run up to 4.5 hours when 100% charged up. However, they're programmed to stop charging at 80%, and it won't kick back in until they think you'll need that extra 20%. That means they won't last as long in your ears before needing put back in the case. And you could end up with dead AirPods Pro if you're out, can't hit up a charger, and your case is out of juice.
Instead of carrying around a portable power bank to charge your AirPods Pro case and AirPods Pro, there's one setting you can disable.
Apple introduced "Optimized Battery Charging" for AirPods Pro in iOS 14.2. If you aren't running that version of iOS, you have nothing to worry about. Once you update, however, the feature is enabled by default. It isn't the first time we've seen Optimized Battery Charging with Apple, as the option is also available for your iPhone's battery, and it works in much the same way.

To disable Optimized Battery Charging for AirPods Pro, connect your AirPods Pro to your iPhone and then head to Settings –> Bluetooth. Tap on the info (i) button next to your AirPods Pro, then tap the toggle next to "Optimized Battery Charging." Your iPhone will give you the option to "Turn Off Until Tomorrow," which you can choose if you want a brief break from the feature. However, you'll need to tap "Turn Off" if you want the feature disabled for good.
