WiFi, Hotspot, Audio Quality, Speakerphone, GPS 

The Charge is yet another smartphone to use Broadcom’s BCM4329 for Bluetooth 3.0 + EDR and 802.11b/g/n WiFi. Thus, it connects at 72 Mbps using one spatial stream on 2.4 GHz WiFi. Range is just what I’m used to seeing with the Charge, there’s nothing to report here that’s out of the ordinary, as the Charge hands on and off of WiFi predictably well just like every other BCM4329 based device.

Likewise the Charge supports WiFi hotspot creation, though Samsung rolled its own software for the Charge and doesn’t use the native Android hotspot utility.

 

The Charge originally received a lot of press for being able to support 10 WiFi clients on 4G LTE and 5 on 3G EVDO, which has been free thus far. Hotspot functionality worked fine through the end of May, at which point it stopped working unless you manually set your date back inside May. After the EE4 update, functionality was restored, but I’ve encountered some problems of my own despite the free LTE hotspot creation period being extended. 

 

Though it’s a bit wonky, the Charge hotspot software is relatively standard fare and lets you do the usual things like set an SSID, WPA/WPA2 pre-shared key, timeout, and view details on individual connected clients. I didn’t get around to trying to have 10 devices connect, but I’m sure it would have worked. As an aside, it seems odd that Verizon’s 4G LTE handsets support more attached users than their dedicated portable hotspot products, and the latter come with tiered data. Something is very wrong with that picture.

I know that audio performance is another huge concern for many smartphone shoppers, and I’ve heard more than one request for some analysis going forward. We’re absolutely going to start doing so, for now however I can say that the Charge has the same Wolfson Microelectronics WM8994 multi-channel codec as Galaxy S. I listened to lots of Google Music tracks on the Charge using some Shure SE535s and the whole thing sounded great to me.

The other important voice quality metric is how actual calls sound. The Charge of course has a unique baseband, and thus I was initially curious to see how calls were going to turn out. I don’t remember ever thinking calls were bad sounding before the update, but after the update things sound excellent. I took a recording using the same method we used in the Thunderbolt to illustrate how good the Charge sounds - there’s no squealing or random drop-outs. I’m actually very impressed. 

Next up is speakerphone volume which is another important metric. We measure using a digital Extech sound-level meter while calling that same number on speakerphone at maximum volume. The Charge is nice and loud here, and that extra loudness is especially useful for more than calls – it’s also nice to have when using Google Navigation.

I guess that brings me to GPS performance. The original Galaxy S series had some big headline-grabbing GPS problems, and the Verizon variant seemed to never quite shake them either. 

I tested anywhere between 4-10 seconds from complete reboot to a good GPS fix on the Charge’s GPS with WiFi turned off. This is a far cry from how broken GPS used to be with every other device. I used the Charge for Google Navigation and drove just north of 800 miles without GPS ever flaking out - trust me, this GPS is tested and passes. That said, that time to fix could still be a bit faster, and you do need a large swath of unobstructed sky for things to work nicely, but it isn’t anywhere near the flustercuck that was Galaxy S GPS.

    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....
  • Impulses - Wednesday, June 22, 2011 - link

    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.
