Is the replacement battery from iFixit different than my original battery? Is the iFixit battery compatible with the new IOS upgrades and resistant to the recently disclosed battery draining practices?
The replacement batteries from iFixit are what I to believe are high quality as they offer 1-year warranty on their batteries. Also the issue of the phone slowing down from bad batteries are not on the 5s model, the iPhone 6 and higher are affected by it in iOS 11.
