Home button and swipe up lag are as good as gone. The phone is snappier than ever before. And the battery life is as good as I have ever seen with an iPhone 7. Overnight battery drain after the OTA update (and charging for a while post that and then taking out the charged) was 1%. iPhone 7 (low power mode is NOT on), 91% after 1hr 20min usage and approx 8+ hrs standby. The other device is my iPad Pro 10.5 Cellular with WiFi on and cellular isn’t switched off either.
