After updating to latest iOS13.4 my iPhone XR gets shutdown even when the batter shows 20%. Tried to browse more on this, it was explained that it is a firmware issue. Can anyone suggest how to recover from this, as its quite annoying to have such behaviour.

  • Hello and welcome! I’ll try and help you out here, Go into Settings>Battery>Battery Health What is the maximum capacity rated at? Usually premature shutdowns are caused by worn out lithium-ion batteries and can occur regardless of the device. – Thunder_Ruler Apr 4 at 22:13

    It's also very helpful if you link to where you saw this was a firmware issue so we can evaluate whether it's legit or not. If it's "some guy" on a forum somewhere saying it's "firmware" (without citing a proper source), I wouldn't put too much stock in that answer as it would likely lead you down a path to nowhere. – Allan Apr 5 at 2:27
