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.

    I've accidentally gone with graphs that lacked that data and updated them with the Thunderbolt results. Numbers from iOS 4.3 will be added shortly!

    Thanks for pointing that out!

    There's a couple of things here. First is that Verizon's EVDO coverage is already pretty good. And instead of opting to go towards 1x Advanced, they've decided to go with a standardized LTE protocol instead to increase speeds; this is a good thing.

    Secondly, while HSPA networks can provide theoretical speeds compared to LTE, the real-world performance is far from the reality of that. OFDM is a far better modulation scheme compared to QAM when it comes to not just realistic peak bandwidth but also range and versatility that there really is no question that it should be the next generation of cellular.

    "OFDM is a far better modulation scheme compared to QAM when it comes to not just realistic peak bandwidth but also range and versatility that there really is no question that it should be the next generation of cellular."

    OFDM and QAM are orthogonal issues.

    OFDM is about how spectrum is allocated. Old school is to give each user one of a few dedicated fairly wide frequency bands while they are in a cell. This frequency may or may not work well for them and be appropriate to their needs.
    OFDM splits the entire spectral range into lots of small frequency bands, and dynamically decides which user gets to use which of these bands, based on issues like both the user needs and how good transmission/reception to that user is at that particular time. In addition, it's easier for the receiver for apply a different equalization to each of these small frequency bands to undo the effects of echos on the received signal.

    QAM is about the shape of the pulse that carries the information within each frequency band. The very specific details of this change from one spec to another, but to first order this is the same as its always been --- the same idea that was in use in 1980s modem, and I assume even earlier in things like microwave and satellite transmission.

    As for ltcommanderdata's point, it is a mistake to assume that 4G is about higher peak speeds. Rather it is about
    (a) a more consistent experience, so that data rates are less likely to fall off a cliff in bad conditions, like at the edge of a cell
    (b) it is about better OVERALL use of the limited spectrum available. Under some conditions this will allow a few users to see very high speeds, but the more likely scenario in urban conditions is that it will allow more users in a cell to get acceptable speeds.

    In other words, it's a way to achieve the goal you want --- better data coverage for more people --- but using technology that ultimately does a better job. Better in terms of spectral usage, and better in terms of more data throughput/dollar spent by the carrier.

    lucky for you verizon's LTE is 3G and not 4G. I think it's something like 3.9G. there is a new 3GPP spec almost every year. HSPA+ is 3.6 or 3.7G.

    real 4G is still a few years away

    so? What's the problem? You get massive speed boosts anyhow which is what the consumer cares about. Nitpicking the little details of the network means jack.

    Brian,

    How much of the battery drain would you say is due to the first gen LTE antenna? I mean, I assume at this point we can call it first gen, right?

    The Thunderbolt is in an odd spot in the VZW lineup. I feel it was rushed to showcase LTE---which it has done a great job of---but the phone itself isn't impressive in any specific way. It's not necessarily faster than other phones, the screen tech isn't amazing, and it's just really thick.

    I agree with you on the qHD point: why can't manufacturers put out qHD with non-pentile matrix? Manufacturing-wise, is there a hold up? Is it an issue of contracts with vendors that need to end? I don't get it.

    I keep seeing these smart phones that really just fall short in a way you think they could easily deliver.

    Oh, and I didn't see you mention HTC's infamous "bump charging." I hear it's an issue with the Thunderbolt, too. Thanks for the awesome review. Super in depth!

    @moids,

    It's hard to say for certain really how much of that battery life hit is the second cellular modem. I originally intended to measure current on both of the MDM9600 modems with an in-line ammeter, but didn't get a chance last time I was in a 4G market. That'll come in the next couple of weeks though. Obviously having two modems is going to affect battery life. The thing gets warm, which to me always is a good indicator that it's using lots of power.

    I don't believe there's any reason why we can't have a qHD screen without Pentile. Keep in mind though that Pentile lets you emulate a higher resolution without needing to have 3 subpixels per pixel.

    I've definitely seen the bump charging situation show up on the Thunderbolt. The first couple initial charges definitely showed that bump charge behavior, later on it got better, but Smart Panel showed a similar trend to that infamous XDA devs thread. I haven't really messed around enough to speak too intelligently about that issue than to say that yes, it does seem to still be kicking around. Maybe the Pyramid/Sensation will change things. I hope!

    I am in a wimax market and they mean 3G data in that quote. 4G and calls are definitely a go

    Interesting! I pinged Qualcomm and was going to wait for them, but updated the article already. Thanks for pointing that out!

    Got it!

    By the way, if you guys implement a perm link feature that's per comment, I can reference certain..."issues"...for vendors to check out ;)

    I want the Bolt because 4G in the Bay Area is STUPID FAST but it just feels like a sidegrade from my Fascinate. I'm pulling 10-12 hours with HEAVY use, 14-17 with moderate use, and well over 24 hours if I barely use it (hah). But, it took me many tweaks and still room for more tweaks.

    I'm almost making pre-loaded Gingerbread a requirement of my next phone; I don't trust carriers/vendors anymore with promises of timetables. Yes, it has come to that: the OS version should be considered a marquee "feature." Sad.

    The day that vendors stop caring about being first to market and care more about putting out a POLISHED experience is when we'll start to see others follow suit. There's no reason to rush products other than to meet a deadline by the higher ups.

    I think it's fair to say that the negative impact of an unpolished product is far more damaging to credibility than the positive impact of being first to market (novelty).

    Hear me, Verizon & HTC?
