My beloved 1020 the other night wouldn't charge and the battery port became very hot. I pulled the charger out and let the device cool over night. The next morning the device still wouldn't charge. I had 5% of battery left and was trying to save a few pictures before the item needed to be serviced. The battery eventually died and I plugged in the charger one last time and it has been working ever since. Have you guys experienced anything like this? I am a culprit to using my Lumia 920 charger on the device here and there. I believe this is possibly the issue. I am glad the device is working fine now. Hopefully it stays this way. I suppose allowing the battery to completely die and cool would be one troubleshoot; and the obvious is to stick with the 1020 charger. Duh to me!
