I’ve attempted to charge my phone with two different chargers, but the highest percentage the phone will reach is 2%. I tried to clear any debris from the charging port, but there is none. What is wrong with my phone?

If you are using it with a Mac, download and install and run Coconut Battery. It has an iOS feature that can give you detailed information on the condition of your battery when you connect it to your Mac. http://www.coconut-flavour.com/coconutba

Have you tried a new lighting cable to charge the device?
