iOS 4 improves the iPhone iPad battery life

Apple made iOS 4 available on Monday, June 21. Apple kicked off an action-packed week today with the full release of iOS 4, its newest operating system for iPhone and iPod Touch devices. The download is free for both iPhone and iPod Touch users, but it is incompatible with first-generation models of either device. The Apple iPhone 3G will support most iOS 4 features except multitasking and home screen backgrounds.

Since the release of the Apple a1185 iOS 4.0 on June 21 last, many people had complained of the autonomy of their phone. Macworld U.S. has conducted a test involving the autonomy of 3G and 3G with firmware 3.1.3 and firmware 4. It was tested under different uses (games, surfing and 3G wireless, downloading a movie, telephone ).

To see what difference iOS 4 made in terms of laptop battery life with iOS 3 on the iPhone 3GS we ran the same tests yet again. It turns out that downgrading an iPhone 3GS is no easy feat and our attempts at doing so failed on the iPhone 3GS phone at the Macworld office.

Here are the results obtained by the U.S. site:

As shown in both tables, the upgrade to Apple iOS 4.0 has caused a moderate increase in autonomy for the iPhone 3G and a substantial increase for the iPhone 3G. Indeed, the iPhone 3G takes 10 minutes more with the firmware 4.0 installed. The iPhone 3G takes him 35 minutes more.

And you, have you noticed such an increase in autonomy on your Apple iPhone Jobs?
