Cellular performance on 4G LTE is actually quite good with the Charge. Samsung’s CMC220 seems to be a top-notch performer among the LTE basebands we’ve seen thus far on Verizon’s LTE network. I performed all my testing in the Phoenix, AZ and surrounding area market, and the Los Angeles, CA market. I ran 361 tests on the Charge connected to Verizon 4G LTE, and like we’ve done before have them reported below in histogram form. 

It’s really nice to see a very distinct normal distribution emerging on the downstream throughput tests, with a standard deviation about 5.5 Mbps centered around 13.0 Mbps. I saw a maximum downstream speed of 36.8 Mbps to speedtest.net’s LA server, and an average of 15.2 Mbps. Upstream throughput is likewise starting to show something of a distribution centered around 5, but the distribution is flatter here. Keep in mind that we have a lot more data here for the Charge than we did the Thunderbolt, and honestly it looks like the two would have developed similar distributions with much more testing. 

I also did something out of the ordinary and thought it might make an interesting thing to report alongside these results. I made a few artists available offline on the Charge in Google Music, and recorded a video of  monitored throughput in System Panel, which is an Android monitoring app and task killer. 

Things are a bit less interesting when it comes to EVDO performance. I’m getting used to seeing a sort of flat distribution of downstream tests ranging between 0.2 Mbps and just shy of 2 Mbps on EVDO Rev.A. On upstream the Charge shows a clustering results between 0.6 and 1.1 Mbps which actually seems a tad faster than the Thunderbolt’s. The Charge in this respect looks like it doesn’t suffer any ill consequences despite having a non Qualcomm CDMA baseband. 

The Charge only reports signal from both the CMC220 LTE baseband and the VIA Telecom 7.1 in steps of 10 dBm. As a result, measuring the phone’s in-hand attenuation was a bit challenging, and ultimately not too exciting. The Charge simply isn’t prone to errant deathgrip again thanks to mandatory Rx diversity. 

The Charge doesn’t use the same antennas to do double duty across either baseband - each gets its own set, and each does its own Rx diversity. There’s a clearly visible strip on the back of the Charge that runs alongside the right of the battery compartment which does WiFi and BT duties. The FCC supplies a nice diagram of how this all works out - Band 13 is for LTE on the CMC220, and bands 2/5 are of course for the VIA 7.5 to do CDMA/EVDO.

    This is a silly statement. The problem is not specifically with CDMA, it is with Verizon, or if you prefer, with IS-95.

    CDMA as an underlying technology has won, no-one is arguing about this anymore. Every future cellular standard (even the GSM ones) utilizes CDMA as part of the suite of technologies that it uses.

    You are correct about this particular problem with the Verizon system (along with various other dumb problems, eg issues in consolidating long SMS messages, or use of unicode in SMS), but are mistaken in what you blame for the problem.

    Got a Charge after having an 1.1Ghz (OC'd) OG Droid on CM 7.0.3 and WOW what an upgrade. Of course, you'd think it would be but its amazing the difference.

    There are two custom roms out, a few kernels, voodoo lagfix and cwm recovery works, except for nandroid (at the moment).

    Weird the review said the T-Bolt gets better battery life... Everyone over at XDA and AC complains about the T-Bolt battery and those that have switched to a Charge have seen a marked improvement in battery life. Don't know what to make of that, but I get 17+ hours of normal use, so I don't complain.

    We've now got 3 Charges in the family and we all love them. Would I have rather waited for the SGS2? Not after using the Charge. It was more than enough of an upgrade for me right now. Dual core will be helpful sometime (Honeycomb? Ice Cream?), but I can do everything I need with zero lag (and I mean zero), so its no big deal for me today.

    Any advice on custom ROMs for the Droid Charge? The Google seems to come up with disparate results, and few reviews. I'd love to hear your thoughts!

    I get around that many hours of usage from my STOCK Thunderbolt. I just don't push e-mail or Facebook notifications as that will kill any phone (like my Storm 2). I find that my Thunderbolt gives me similar battery life that I was seeing under my Droid 1 but on LTE with the Thunderbolt.

    @ GrizzledYoungMan: I'm currently running Altered Beast v5 (its a themed rom) with gummyCHARGED 1.7.5 kernel, voodoo lagfix enabled. There's also a gummyROM that's more AOSP than Altered Beast. To each their own.

    @Omega215D: Not having a T-Bolt, I can only relay the comments I see on the Charge boards at XDA and AC. If you get great battery life, then great! FWIW, I also got great battery life "STOCK", but wanted to de-bloat and get rid of most of the poop brown that Samsung seems to like.

    The physical buttons are great. I wish my other phones had those.

    I had this phone for 3 days and returned it.
    The voice quality had more pops and cutoffs than my nexus one on t-mobile.
    Small difference in voice quality, but I found it really annoying.

    The touchwiz ui is awful.
    The browser lacks the +- on screen buttons that zoom in and re-format web pages to screen width. With touchwiz, you can zoom in, but end up scrolling left and right - I HATE that.

    The disabled tethering was the final straw.
    I only use mobile data with my laptop a few times per year, so paying fees for all those months with no usage is not acceptable.

    On the plus side, verizon was very good about the return.
    $35 restock, and they pro-rated the usage to the days I had the phone.

    I felt the same way when I contemplated about returning my Thunderbolt for the Droid Charge. The screen on the Charge is great and the battery life seemed to be better (looking at the battery meter on an unplugged Charge and its usage) and for some reason didn't feel as slippery as many reviewers noted.

    Playing with the phone for an hour or so and it was a bit of a pain. The lag and lack of web reformatting got to me. Plus there isn't any LED notification light.

    With 2.3 supposedly on the way I have no real reason not to like my Thunderbolt but Sense UI is great to use without being on 2.3.

    You seem to be way more thorough in your phone reviews. Please review the EVO 3D, for Sprint. The last guy just seemed to speed past everything. With Android devices, battery tests really matter, but the guy that reviewed the EVO 3D barely spent a paragraph on it. He seemed biased against the either the phone or the carrier from the outset. Maybe the 3D moniker ruffled his feathers....

    What are you talking about, Anandtech hasn't reviewed the EVO 3D yet, they ran a hands-on performance preview but that was it. I think they're gonna be doing the Sensation and Droid X2 first, but I hope they tackle the EVO 3D after that...

    Other reviews on the web are so contradictory it's not even funny, and no one seems to be able to run a proper battery test. Honestly, all the news blogs reviews are mediocre at best, it's pretty dad when a CNet review actually gives more detail than almost anything else (Laptopmag's was pretty thorough too, still nowhere near AT standards tho).

    I'm actually holding off on upgrading while waiting for the AT EVO 3D review, even tho my EVO 4G has been suffering from sporadic reboots lately (they seen to be heat related). If the Photon wasn't on the horizon I might've taken the plunge knowing I have 30 days tho.

    I think you're alluding to our hands-on piece with the EVO 3D from a meeting with HTC at Qualcomm Uplinq. We're absolutely going to review the EVO 3D, actually that's scheduled now. Anand is going to do that review however since there is no WiMAX in my state sadly. I've got the HTC Sensation, however.
