Apple has been in trouble in the near future, the 2017 iphone 8/8 plus sales have been cold, because of the battery at the beginning of this year, led to many users feedback that the iphone performance dropped, even Apple’s genius of the battery inventory by the old iphone users, it is a double whammy.
Perhaps in response to the new system’s impact on batteries and cell phone chips, Apple has recently opened the door to old equipment downgrades. The old models from the iphone 5 to the iphone 7 Series can be downgraded. According to Apple’s firmware website ipsw.me, iphone 7/7 Plus, iphone 6s/6s Plus, iphone SE, iphone kv Plus can be minimized to iOS 10.2,iphone 5s/5c down to iOS 7.0.3, and the iphone 5 can be reduced to iOS 6.1.3 a few years ago.
If you think that the new system does have an impact on your iphone, you might as well downgrade the system. The operation is very simple, just download the corresponding version of the iOS system firmware, and then connect the phone via itunes, on the System update page hold down the “Shift” button or the Mac “option” button, then select the appropriate firmware.
A special reminder is that because of the large number of degraded users, the Apple server is a bit overwhelmed and may require a few more attempts to activate. In addition, we do not recommend the use of the main machine to downgrade, if you have a temporary need for the old iphone, perhaps you can try the downgrade operation.
