HTC Desire Z: An in-depth and nerdy review.

This review differs from other HTC Desire Z reviews because I’ve actually been using this phone as my only smartphone quite intensively, and because I’m writing up, in great depth, my iopinion as a gadget-toting ex-Linux-zealot computer science nerd. Take that engadget!

As many of you know, I was completely in love with my previous smartphone. Not surprising, seeing as the Nokia e71 is perfect, at least hardware-wise. However, partly due to Symbian (Nokia’s operating system) really dragging its heels (Nokia, does your mobile OS really have to feel like it teleported in from 1970?) and partly due to Android (Google’s mobile operating system) doing the exact opposite, I’d been not-so-patiently waiting for the right Android-running telephone to come along so I could start drinking the Google Kool-Aid.

Enter the HTC Desire Z, known in the US as the T-Mobile G2, a micro-laptop with built-in mobile phone, or a flashlight with built-in laptop and phoning function, whichever you prefer:

After having read a gazillion mobile phone reviews and months of intensive pondering on what physical keyboard-toting smartphone I would get after two years with my E71, I had narrowed it down to a Blackberry Bold 9780 or the HTC Desire Z. Blackberry lock-in (if you don’t pay RIM their monthly protection money, half of your telephone stops working) together with my penchant for all things Google led to the purchase of the HTC Desire Z from the smartphoneshop in Rotterdam (highly recommended: It’s a web shop, but I just popped in there on a Sunday to get the phone and sort my contract issues) along with a 1 year T-Mobile iPlan 150 contract (150 minutes, 150 texts and unlimited 2 Mbit/s internet).

The thing has now actually survived three weeks in my hands being super-intensively futzed around with, so it’s finally time to talk honestly about our experiences together.

The Good

Coming from the Blackberry-style Nokia E71 keyboard, a finely tuned mechanism for high-power text entry, it took a while to get used to the Desire Z’s slide-out keyboard. However, I’m now completely convinced that the keyboard is absolutely worth the extra 40 or 50 grams. Many have complained, but the mechanism is beautiful: It slides in and out with a satisfying PLOK. There are no springs or spring-loading in sight, as this business all elegantly gravity-powered. Yes, if you’d try to lie on your back holding it in front of your face, gravity starts working differently and the thing will fall open. My advice: Pick some other activity for performing whilst lying on your back. The keys themselves are nicely separated. Perhaps they could have been a tad less stiff. Importantly, I find that clipped nails greatly enhance my typing experience. To be quite honest, it’s a fine keyboard, but the still wins in this regard.

The phone has a great feel: With its 180 grams and subtle brushed metal finishing, it exudes quality when picked up. However, if you’re a smaller person, you might want to try it first before making the jump. I find the weight and form factor just perfect, but that’s of course all relative. I carry the thing, without a cover of any kind, in my trouser pocket. (Oh who am I kidding, I never wear trousers. They’re jeans. By the way, did you know that someone has a patent on reinforced trouser pockets?)

Finally, the software integration on this telephone is beautiful. So with Android 2.2.1 at the time of writing, and the HTC Sense layer, you receive a mail or check your Friend Stream (twitter, facebook and whatnot), tap on an attachment or link and the relevant application opens. New apps can register as handlers, so after you’ve for example installed Dropbox, long tapping on some files will give you the choice of syncing them with your Dropbox account, and so on. Because this is more a micro-laptop than a telephone, I definitely feel far less constrained when having to work on it than was the case on my E71: I can edit documents, SSH to places, review presentations use all forms of webapps, without anyone having to know that I was trapped on a train or some other odd place for a few hours. Also compared to the Apple 3GS with iOS 4.x, the Desire Z blows it out of the water in this respect, due to both Android and the keyboard of course.

Finally, and this is a good point of any Android device, the apps and the Android Market integration. Further down I will briefly discuss my favourite apps at the moment. For now it suffices to say that there are a gazillion apps, all installable (and the non-free ones purchasable) with a single tap. With a certain amount of searching, you invariably find that one app that you believe will help you be more effective / productive / happy / successful in life, at the very least for the subsequent five minutes. In other words, your toy is able to acquire completely new functions, not always equally useful, at the tap of a button.

The Bad

The 1300 mAh hour battery is a definitely weak point of this telephone. After the initial conditioning discharge-charge cycles, the battery did indeed go from utterly crappy to merely disappointing. It now lasts from about 8:30 in the morning till about midnight and on days when I spend more time than usual futzing with the thing, the hungry beast starts complaining at about 20:00 that I should really consider giving it something to eat. This is in spite of the fact that I mostly explicitly switch off the wireless (I know it times out by itself), keep the GPS switched off, switch off automatic syncing quite often and keep the screen brightness on automatic. If the Battery Usage app can be believed, the screen is the biggest culprit. Usually it consumes 60% or more of the power budget. According to CurrentWidget, the phone eats about 30mA in standby, about 140 mA when I’ve just switched on the screen and about 300 mA when I’m just browsing the interwebs.

I also do have some small gripes with the software:

  • Why in Android GMail 2.3.2, when I want to reply inline to an email (that’s new functionality), does it put my signature ABOVE the email that I’m replying to? The standard is that the signature should go BELOW, as is the case with web GMail. There also doesn’t seem to be any way that I can configure this. I’ve started a thread on the Google Mobile help forums, but apparently no-one finds it interesting enough.
  • Why do I have to root my phone or install the whole SDK and connect the phone to my PC  if I simply want to take a screenshot?
  • Ok sorry that last one was REALLY a minor niggle.
  • Why can’t I change the number of home screens in HTC Sense?
  • This one’s quite serious: Why is can’t I voice chat with Google Talk users from my Android phone? Google Talk is beautifully integrated, but no voice chat to be found, which is verging on the ridiculous.
  • Every so often, the Gallery app just forgets a bunch of photos on the SD card. Either it doesn’t list them, or it shows them as broken images (can’t be loaded). Unmounting and mounting the SD card fixes this, but what an annoyance… (android 2.2.1 update)


Even worse than the battery is the dismally performing optical trackpad. If you’ve ever played with one of the new Blackberrys, you know that an optical trackpad can work just perfectly, almost seeming to read your intentions rather than your finger motion. The trackpad on the Desire Z either reacts very slowly, i.e. vigorous finger motion results in very little cursor motion, or not at all, sometimes requiring 2 or even 3 swipes before the cursor does anything at all. What’s really frustrating, is that if I swipe with a piece of cloth (read “t-shirt”) over my finger, the thing works exactly like it should. Furthermore, swipes over the trackpad often end up on the “menu” or “back” touch keys, resulting in completely unintended consequences.

Now on a touch screen phone, and the Desire Z has a really great touch screen, the trackpad is less relevant, but why did HTC go to the trouble of integrating it there?! Also, why did they pick the crappiest trackpad they could find when the rest of the phone (ok, forget the battery for a moment) is constructed from top notch components? The trackpad could have been a really useful input device, allowing for fine cursor positioning for example.

Let me calm down for a while, and conclude this section with the following disclaimer: In the meantime, I’ve played with the trackpads on two different HTC Desire Zs. One of them was more or less the same as mine, the other seemed to be much better. I’ve also experimented with fingers belonging to different users than myself, that doesn’t seem to be a factor. Whatever the case may be, the trackpad on MY telephone is almost useless, but I’m going to test on more Desire Zs to establish whether mine is a dud, or it was a design error on HTC’s part. smartphoneshop has offered to take my phone back, but I have great difficulties parting with it for more than a few minutes, and it’s not sure whether a repair will even agree that something is wrong with the phone.

My favourite apps

You can see all of the apps I currently have on my telephone by going to my AppBrain user page. I’m only going to mention my favourite ones in the  following list:

  • AppBrain: You create an account on AppBrain with your Google credentials and then install the app on your phone and BAM, you have a much nicer interface for app installation, including personalised recommendations.
  • TweetDeck: Get and give your Twitter, Facebook and Buzz fix in a beautiful and functional column-based interface, plus that you can run variants of the software on your Windows, Mac or Linux running PC.
  • Note Everything: The HTC Desire Z doesn’t come with a default note-taking app, but the free version of Note Everything performs this function perfectly. It’s small and fast, can save to and load from Google Docs, and does search as you type! I bought the Pro version, as it has more types of notes, can backup the your whole archive to SD, and I wanted to support the authors.
  • SipDroid: I tried 3CXPhone and LinPhone, but SipDroid’s perfect integration with the calling function of the telephone won me over. In spite of the integration, it’s easy to exit when you don’t want to do SIP calling anymore.
  • Widgetsoid: Use this to setup pretty buttons on your homescreen for toggling and configuring bluetooth, wifi, syncing, screen brightness, and much much more.
  • QuickOffice Connect: I bought this office suite for its great integration with multiple Google Docs and Dropbox accounts, of course the idea that I can edit MS office format docs on my phone and the really fantastic PDF viewer that’s included. Nice tidbit: When you do a full text search, it searches through all local documents, as well as everything on all linked Google Docs and DropBox accounts. That’s pretty neat!
  • Jorte: The built-in calendar app sucks, wasting valuable screen real-estate on overly large on-screen buttons and huge fonts. In the week view, it’s not even able even to show the appointment label! Jorte solves all these problems, and even syncs with your google tasks. It even shows appointment names in the month view! In the near future, I will also be trying out Pimlical for Android, as I used to be a DateBk6 addict in my Palm days.


In spite of its flaws, namely the disappointing battery life and the hardly functional trackpad, the HTC Desire Z is the information age equivalent of a Swiss Army knife. It has everything you need to function, no, to excel as a data-wrangling nerd. You can go on the road, confident that you can wrestle to the ground anything thrown at you via the internet.  If your battery survives long enough, the built-in flashlight app (the camera flash is very bright) could even help you solve some real-world problems after dark. Accentuating the nature of this power-phone, a number of my more nerdily-inclined but socially adept friends and colleagues have acquired the Desire Z or are at this very moment lusting after it. If you in fact need a micro-laptop with phoning function and you can live with the charge-me-every-day battery and you don’t mind the trackpad, this is just the device for you.

If you have questions or suggestions, please leave me a comment below. I’d like to update and refine this review as new information comes in.


  • HTC tech support is good! I mailed concerning my diacritics question, and was answered (in Dutch) within a day.

  1. Thanks for the write-up. Makes me partially happy. For the last few days / weeks I saw everybody walk around with the coolest android phone on the market (well, at least 2 people with the coolest, some others with other android phones, and one person with the not-so-cool iphone 😉 ) and every day it makes you decide you def. need one too, if only to be cool during the coffee breaks.

    However, this review made me see the, at first sight, hidden downsides of owning a fancy phone. My current battery lasts over 3-4 days with wifi enabled, about 2-3 hour talk time and rest sms/agenda stuff. I cannot do fancy app stuff on it and therefor do not need to worry about their battery use ;). My abo costs me 8.35euro / month for 375 minutes and 150 sms w/o internet, including internet it would cost me 10 euros more.(However, I disabled inet because I am at wifi spots about 80% of my time, and maybe 99% of the time I use my phone or am able to use my phone)

    So partially happy, I cannot be cool at the coffee corner but am still paying far less than you guys (muwhahah) and am able to reply on emails through my phone 99% of time. However, I do not have whatsapp as I still use a win6.5 phone (originally win mobile 5 even) and whatsapp does not support windows phones.

    Bottom line, damn I want the money to buy that fancy phone too :'( :'( :'(

    P.s. thanks for the apps, was looking for that Widgetsoid for my gf’s phone :).
