Update: Test Result for all Extended Battery for Palm Pre

So you got a Palm Pre, love everything about it but the battery life and maybe the lack of official apps. We know come Fall, the App Catalog will be exploding with cool apps. So only thing left is the battery life. You can buy a 1400mAh Palm Pre extended battery that will add about 20% more juice to your Pre, which we reviewed just days ago. I'm sure this is enough for a day's worth. But if you need your Pre running for 2 or even 3 days with out a single charge, you can go with Amzer's 2800mAh extended battery or Amzer's 3800mAh super extended battery. Both of the 'super extended batteries' comes with their own battery door due to the size increase of the battery. And also note that these back covers are not TouchStone compatible, maybe in the future.

Read on for our In-depth look and comparison of the standard and extended batteries + back cover. And stay tune for our Test results in the coming days. You can read the test results of the 1400mAh here.

Battery Size Difference: 

Right off the bat, you can tell the difference in size. The 3800mAh is about 3x the height of the standard battery, where as the 2800mAh is twice, and the 1400mAh has identical dimensions.

Back Covers (Side View)

The standard back cover is 4mm thin, 2800mAh's is 9mm thin, lastly -- 3800 is 15 mm thick.

The extended battery back covers feels cheaper, but definitely sturdier.

Amzer vs. Seido Battery Door:

Unlike Seido, Amzer preserved the curves that is known for the Pre. And Amzer's battery door has the Piano back finish like the standard back cover (Will attract finger prints), where Seido has a matte finish.

Reason why the extended batteries need their own back cover:

With the 3800mAh back cover on, you Pre is also a wireless/wired mouse:


We haven't tested the super extended batteries yet, but based on our results from the 1400mAh battery, these will offer the extra juice like promised. I'll recommend the 2800mAh over anything else currently on the market, because it offers a lot more battery life vs. Standard, plus it feels really good in the hand, especially while typing. But if you really need even more juice, go for the 3800mAh

We are hearing that the Seido extended back cover messes with the camera flash. 

So we took some photos with flash with the Standard and Extended Amzer's back covers. Looks fine to us, and some how the photo taken with the 2800mAh back cover came out the best.
