maximum capacity shows 81

You are about to be needing a battery replacement, 80% is the threshold. Now occasional shutdowns are a symptom of a failing battery and Apple may make an exception in replacing your battery if you tell them that. Otherwise they usually don’t replace it till 80%, that’s when most symptoms start. Please visit your nearest Apple Store’s Genius Bar or Apple Authorized Service Provider to schedule the battery replacement.

Hello!

Go to: Settings > Battery > Battery Health (& Charging), and let us know what the Maximum Capacity is at. Thank you.

Getting your iPhone Out of this Boot Loop:

Your iPhone is stuck in a Boot Loop. This typically occurs when you go about installing an update, and it stalls while in the process. Use my User Tip: How to Fix an iPhone in a Boot Loop - Apple Community

“hi: thanks for reply.. i have already done two time reinstalling the ios to latest version using itunes but still problem exists... Hope charging port flex need to be replace with OEM i think so...”

You are welcome. Report back, if fixed, and how. You might want to try using another computer, and be certain your computer is plugged in and charging while performing this.

Thanks Z

Sorry, good work though!
