Verizon iPhone 4 Teardown: Smaller Battery Than GSM

The Verizon iPhone 4 will finally be released on Thursday and among our recent posts on this long-awaited phone are the fact that it smashed first-day pre-order sales at Verizon, the story of an early first delivery, and also a ponder over some compelling reasons not to buy it yet but maybe to wait for the iPhone 5.

Here at OSM we do love a good teardown and Donald Melanson over on Engadget gives us details of a teardown of the Verizon iPhone from iFixit, who are well known for such things. One of the differences between this iPhone for Verizon and the AT&T iPhone 4 is a lighter battery than the GSM version, although the CDMA Verizon iPhone does in fact have the same capacity.

The Verizon iPhone also has a revamped mechanical vibrator, which has also moved position and evidence at last of the much-rumored changed chip which we thought might come to the iPhone 5 and iPad 2, a Qualcomm MDM6600 “world-mode” chip to be precise, which can support both GSM and CDMA but at the moment doesn’t. The reasoning for this that iFixit comes up with is the possibility of the antenna redesign being more simple on a purely CDMA model.

Daniel Eran Dilger over on Apple Insider also looks at the iFixit teardown of the Verizon iPhone and notes that along with the fact that Apple still chose this to be a CDMA-only phone the phone had no SIM card slot anyway, necessary for the GSM AT&T network. Dilger also points out that the lack of a SIM card slot makes it more difficult for users to unlock the Verizon iPhone 4 and so enable it to be used on other carriers. What are your thoughts on the changes made for the Verizon iPhone 4? We’d welcome your comments on this.
