Apple iPhone 17.3 system don't update, mine is Apple 13, in addition to the original system from the factory, 17.2.1 is the best and most power-saving system so far, I must be the pension system, I don't know if everyone has updated, Apple 13 I was the first batch to buy, now the battery is 85 percent, it's better to open 4G, if you open 5G three charges a day, now 15 price reduction is really much, I don't know how much I need to pay for 13 for 15. #Apple13, you're worth it# #Fruit fans, come and see# #I'm going to make micro headlines# #苹果系统17.3#
