Since the latest update my phone has started to reboot constantly. When charging it will go to 100% then when you unplugg the charger it drops down to around 50% and starts rebooting itself whenever you try to do something with the phone
Hello sir.I understand your problem. It has probably been caused because of improper or incomplete updates. Had you updated your phone without putting it on charge? Maybe it died while updating because of low battery.
Anyway, first thing that i would like to suggest you is do a soft reset. (press power button and volume down button for 13 seconds.)
Once done, go to settings, updates, and check if you have any pending. Complete the update if you have any.
If you don't have any, but still see the issue, I would suggest you to reset your phone, but that would mean everything will get deleted. So take a backup of your data first, and then using Lumia recovery tool, reset your phone. It should work well.
Also, please join the windows 10 community.

we might just be able to help you better here.
Good day. Hope your issue gets solved.
