3G iPad battery life 1.5hours less than iPad on Wifi

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 Apple’s 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!

Mounting iPad 3G in your Car

With the launch of iPad 3G, more and more guys will be thinking of mounting their iPad on their car. iPad 3G not only can have wireless internet regardless where you are, it is actually equiped with GPS, where you can have turn by turn navigation just like iPhone but with a big big screen.

Videos below are mounts built just for the iPads:

iPad SPEED Test

Finally the launch of iPad 3G concluded  the last member (and most important) of the iPad family. Gizmodo have done a series of Speed Test of the iPad Family.

Overall iPad 3G’s Speed is slightly better than iPhone 3GS, might be due to faster processor, but the speed bump is just slight improvement.

Here’s a sample of the results.

5 Antennas in iPad 3G

Phyiscially there ain’t much difference between a Wifi iPad and a 3G iPad other than the inclusion of a black plastic RF window on top of the iPad for better antenna reception.

But the inside of a 3G iPad is amazing, 5 antennas in just a small size iPad to ensure you will get great surfing experience.

Here’s the quote from ifixit:

There are actually FIVE antennas in this iPad: Two antennas handle the cell reception — one is in the RF window on top, the other attaches to the LCD frame. A single GPS antenna is also housed in the RF window on top. Just like the iPad Wi-Fi, there are two antennas that handle Wi-Fi / Bluetooth connectivity, one in the Apple logo and another to the left of the dock connector.

* You heard that right, folks: Apple looks to be using the entire LCD frame as an antenna!

* Who would’ve thought: Apple uses the same 3G baseband processor in both the iPhone 3GS and the iPad 3G.

* The baseband processor in question is the Infineon 337S3754 PMB 8878 X-Gold IC. It was actually white-labeled on the production unit, but with enough sleuthing we were able to confirm its true identity.

* The iPad 3G has a Broadcom BCM4750UBG Single-Chip AGPS Solution, whereas the iPhone 3GS uses an Infineon Hammerhead II package. Big win for Broadcom!

* Apple did not change any major suppliers between manufacturing the pre-production unit they provided the FCC and their final production run.

Using the entire LCD frame as antenna is a superb concept as iPad is nothing but a big LCD screen. Haha!

3G iPad jailbroken hours after launch!

Jailbreaking iPad seem easier than ever, merely hours after 3G iPad’s launch, it has been jailbroken.

Recently we have posted how iPad Wifi Version was jailbroken within 24 hours after launch, seem like iPad 3G has nothing too different, and able to jailbreak within hours.

Lots of Apps, especially streaming apps need you to be on wifi for the streaming to play, thus it will be one of the main reason for jailbreaking, making your iPad’s Apps able to stream even on 3G network.

Here’s a video on the jailbreaking of iPad 3G:
