Seems like it broke your keyboard too. Clear the cache from recovery mode, give it a few charge cycles to settle and if you're still having issues look at the pinned battery threads for further instructions. The same advice that gets repeated here at least a dozen times a day.
Use the search bar next time. It is there for a reason.

Use you phone and upload some screenshots when the battery goes under 10%
