I MUST update to the latest iOS to get battery replacement?
yea it's like the topic said, I want to get a battery replacement within the 1 year warranty period.
I bought an iPhone 11 on 13-09-2021 in Malaysia.
Now I am studying college in Taiwan, I still can claim warranty right?
Then I have a ques, it's do I MUST update to the latest iOS before walk-in to the authorized store?
iPhone 11, iOS 14
