Before the launch of iPad 3G, many have comment that iPad’s battery life is extremely good, better than promised by Apple. Thus more people are wondering if iPad 3G’s battery will last as well, as we all know 3G sucks battery life off every device in the world.
iLounge have done some prelimiary tests on the battery life of iPad Wifi and iPad 3G. Refreshing/Reloading the page with either Wifi on or 3G on. Seems like the results are reasonably close to what Apple have promised to be 10hours on Wifi, 9 hours on 3G:
Our prior iPad with Wi-Fi battery tests found that Apple was generally at least a little conservative in its estimates; for instance, we put the Wi-Fi model through a web torture test with repeated 1-minute refreshes of a large, completely loaded page for 10 hours and 21 minutes on 50% brightness over 802.11n. Repeating the exact same test on the Wi-Fi + 3G model with 3G turned on and Wi-Fi turned off, the iPad achieved 8 hours and 38 minutes of continuous reloading and displaying — 22 minutes shy of Apples estimate.
Note that in normal surfing, pages are not really refresh every 1 minute or so, so the results in real life surfing will be different, but we will have a rough gauge of the battery life. It is relatively impressive to get close to 9 hours of 3G surfing!
