Hi bro ,
I have iphone 14 pm and now its about to complete 1y in couple of weeks and i have 95 battery 
percent is that good or bad ?? …
2. Can i put apple plus care in service center and what could be the price
its totally good bro. you can continue following the same charging practice. apple care+ can be purchased only within 60 days from the date of purchase of iPhone.
Right now you may check with Protect+ from iPlanet service center which is similar to applecare+ but third party option from servify and iplanet combined.
Still its useful and you can apply it within 1 year warranty period. have to visit iPlanet to get that after they check the device bro. Its optional ofcourse. You may go for Protect+ only if you are thinking about any damage could happen within next 1 year period and don’t want to spend huge amount on service fee.
