Why wont my galaxy s4 charge?

[AC Question]

My s4 died last night, then popped up with a screen with the android avatar saying "downloading... do not turn off target!!", I had it on the charger all night, took out the battery and put It back in this morning. it turned on but now wont charge with any charger.

Welcome to AC.

It may be worth trying a new battery.

Welcome to Android Central! That screen is Download Mode, which comes up if you try to power on by pressing Power and Vol Down. If's used to download firmware to the phone--as long as you're not connected via USB to a computer, it's safe to shut the phone down and restart.

If it's not charging, the first thing I'd try is a new battery.
