Size: Stock vs 3500 mah vs 2150 mah
For those of you who have purchased the upgraded batteries, can you please post pictures? I'd like to see the batteries and doors actually mounted on a phone :)
Also, does the added size coupled with the weird shape of the back door present an awkward situation handling the device?
Pics!!! - Stock vs. 2150mah vs. 3500mah
Here are the pics I promised. We pitted the stock HTC 1300mah vs the HTC 2150mah vs the Seidio 3500mah.
First, the weight of the phones on a postage scale.
Note that the postage scale is not a good one. It won't register a penny or a nickel, and it weighed a U.S. quarter at 0.3 oz.
Phone + Battery + Back:
Stock - 4.6 oz.
2150 - 5.5 oz.
3500 - 5.7 oz.
You will see, in the images, that the Seidio 3500 is not much larger than the HTC 2150. In fact, I would be surprised if the difference is 1mm. The odd thing is that the backs are so different. We tried to put the back from the HTC 2150 over the 3500, but it wouldn't snap down. That's a shame, because the back for the 2150 looks so much nicer. In my opinion, the back for the 3500 looks like a stack of flapjacks.
Either way, both the 2150 and the 3500 feel really sweet in the hand, and there is very little difference in weight (less than the weight of a U.S. quarter, according to that scale). So, if the 3500 performs as well or better than the 2150, it's a win. I still think Seidio should have done a two-step design on the case, instead of the three-step.
