Take the battery out and let it cool down for 30 minutes (or some minutes in a fridge - not freezer).
Meanwhile plug in the phone without the battery for a while. You should see the following behavior:

• the phone vibrates
• the display shows the Fairphone logo for a second or so
• the LED lights up for another second or so
• this happens over and over again

If it does not help to wait longer test the above from wiki
