Why my phone keeps on stop charging since the new ios 16.3 update

Hello jowayne144,

Thanks for posting in the Apple Support Communities. We're happy to look into this with you.

Have you noticed that your iPhone stops charging at a certain percent? For example, does it stop at 80% charge? If so, you may have Optimized Battery Charing enabled or your device might be getting too warm and needs to allow time for it cool off before continuing to charge. This is a feature that was introduced with iOS 13 and is meant to help extend the lifespan of your battery.

If your iPhone or iPod touch won't charge - Apple Support

If your device stopped charging at 80 percent

Your iPhone might get slightly warmer while it charges. To extend the lifespan of your battery, if the battery gets too warm, software might limit charging above 80 percent. Your iPhone will charge again when the temperature drops. Try moving your iPhone and charger to a cooler location.

iOS 13 and later use Optimized Battery Charging to slow the rate of battery aging by reducing the time that your iPhone spends fully charged. Your iPhone uses on-device machine learning to understand your daily charging routine so that it can wait until you need to use your iPhone to finish charging past 80 percent.* Optimized Battery Charging is active only when your iPhone predicts that it will be connected to a charger for a long period of time.

If this doesn't align with what your'e experiencing, please answer the questions below and we'll use that information to help us research potential causes and solutions.

• Are you charging your iPhone wirelessly or with a wired connection?
• If using a wired connection, are you using an Apple branded cable and charging block?
• Is your charger plugged directly into a wall outlet or are you using an extension cord or surge protector?
• Since the health of your battery can impact charging and charge retention, what is the Maximum Capacity? This is found in Settings > Battery > Battery Health.

Best regards.

both my iPhone 7 and CE 2nd gen do that. I think if you do a forced restart it may fix it. Go to Home Screen Hit right button screen will turn off. Push volume up release! Volume down push n release it now do right button n hold it til you see the Apple it may take some time
