If your iPhone won't charge, be sure to check the cable, Lightning port, and AC adapter. You can also try restarting your iPhone, updating the software, or restoring it. If your iPhone stops charging to 80%, it's due to the optimized battery charging feature.

The maximum amperage approved by Apple for iPhone chargers is 2.1 amps. Unlike many third-party chargers that can damage your iPhone, these will charge your iPhone quickly and safely. The iPad charger is 2.1 A and Apple says it's fine for iPhones. Remember that it's the iPhone software that says “Yes” or “No” to charging when the iPhone is connected to an accessory.

One of the most common reasons why an iPhone won't charge comes from low-quality third-party iPhone charging cables that people buy at gas stations. If there's no visible damage to the outside of the cable, try connecting your iPhone to a USB port on your computer to charge it instead of using the wall adapter that came with your iPhone. In fact, when looking through the iPhone's charging port, it looked like there was some kind of build-up, probably lint accumulated from carrying the iPhone in my pocket.
If your iPhone suddenly works again after you plug it in, you've identified the reason why your iPhone isn't charging a faulty cable. If your iPhone still doesn't charge or doesn't respond to a forced restart, go to an Apple Store, an Apple-authorized service provider, or contact Apple Support. If you go to an Apple Store to repair your iPhone and the phone is damaged by liquid or physical damage, the only option they offer is to replace the entire iPhone. If you had photos, videos, or other personal information on your iPhone and it doesn't charge, Apple will say they're gone forever.
Damage caused by liquid can cause your iPhone's charging port connections to short circuit and cause all kinds of problems with your iPhone. Check out my article on how to restore an iPhone with DFU to learn how to put your iPhone into DFU mode and cross your fingers before trying.
