An interesting take from the teardown is that the DROID 2 has the same 1390mAh battery that the first DROID had, however talk time in 3G mode is estimated to be nearly ten full hours instead of the 6.5 we had in the original. And that's with the Texas Instruments OMAP 3630 CPU clocked at 1GHz, instead of the 600 MHz of its predecessor. The combination of Froyo optimized for a TI OMAP chipset, produced with the 45nm technology, has brought to the DROID 2 a whopping 49% increase in battery life!
It certainly looks like those claims for 30% increases in battery life when moving from the 65nm to the 45nm process, and then another 30% when dual-core chipsets of this kind hit from TI, Qualcomm and Samsung, is not vapor ware. If such talk times can be achieved on an Android handset, then the smartphone industry is certainly heading in the right direction with the new 45nm chipsets, like the ones we find on the Motorola DROID 2 and Samsung Galaxy S phones.
There was a mention in the iFixit writeup of the antenna position, which is cleverly just a gold wrap around the speaker at the bottom. We think that antenna position design decisions should be a must in phone disassembling articles from now on in light of certain events. Also, it is amazing how small the camera module actually is.
