HTC Thunderbolt Review: The First Verizon 4G LTE Smartphone

The other obvious oddity is software. Back in the day HTC famously built their own CDMA2000 support into Android 2.1 1.5 and released a host of devices. Android 2.2 1.6 (Got my versions screwed up, thanks Brendan!) swung around and built all of that in natively, and most of the world didn’t notice much difference, thankfully. Odd quirks such as cell standby showing inordinate power use in "about battery use" were about the only manifestation of this hack, outside phone test menus.

History loves to repeat itself, and this time the situation is that Android 2.2 lacks native awareness for 4G LTE. As a result, you get odd things hanging around like the 20 MB YouTube WiFi upload restriction, and the 128 MB mobile upload (for any connection) file size limitation. I’m sure a number of similar things are floating around, all of which previously pandered to the limitations of 3G that have no business being around anymore.

My closing thoughts with regards to LTE on the Thunderbolt are that it’s impressively fast, fast enough that it now feels like loading through pages is now CPU-bound instead of network-bound. In many ways that’s a much better situation to be in, as SoC updates follow Moore’s law, and network updates seem to eons to roll out due to spectrum reallocation, network build out, testing, and finally hitting go. Dual core is the solution, and it’s a shame the Thunderbolt isn’t. Right up that alley is MSM8960 and MSM8930, which are dual core and single core Krait, respectively. A quick refresher on Qualcomm’s naming scheme for SoCs is that the second digit connotes what cellular network standard support is built in: 2 is for 3GPP family only connectivity (GSM, EDGE, WCDMA/UMTS, HSPA), 6 is for 3GPP and 3GPP2 connectivity (so everything above, plus CDMA2000, EVDO, e.t.c.), and 9 now will mean LTE. 

With both MSM8960 and MSM8930, the LTE modem is built into the SoC, resulting in both smaller overall package size and likely notable improvements in power consumption from everything being made at one process. At that point, LTE becomes much less of a design challenge, and I expect battery life to be better as a result. If you want something to wait for, it’s MSM8960. The other thing to watch for are the successors to MDM9600 - the MDM9615 and MDM9625, which were announced during MWC. The former is targeted towards a 28 nm process offers some performance increases alongside reduced power consumption and a smaller overall package, making it ideal for handsets. The latter is a category 4 device (as opposed to category 3 for the former two) and thus offers a higher level of performance, and likely will go into USB modems and other data-centric platforms.
