If your battery is very hot this may damage your battery lifespan! If your screen dropping brightness while your phone is hot, try to immediately cool it as long as your brightness return. Don't play heavy games while charging your battery! Or you can play but only if battery will shown 100%
P.S. Try to find new battery (new) and replace the battery. Battery must be charged from 0% to 100 at least once per month! If not then the battery will loose her capacity! That's why new phones from Apple may have battery issues. In the store shelf iPhone may lying month or years who knows? That's why ours iPhone having issues with their batteries.

I have had terrible luck with my battery since last iOS upgrade. I just spent $7 on an OEM battery and took 5 minutes to replace my original battery. I easily get 12-15 hour run times out of my phone now.
