Signal
Signal attenuation due to holding devices is now a very present concern. As usual, we’ve measured the BlackBerry Torch in three different positions and found that the Torch drops around the same amount of signal as other devices, and of course less than the iPhone 4.
The cellular antenna on the Torch is at the bottom, as is the case for most devices. You can see the flex PCB which houses the antenna at the bottom quite easily right here. It's that different color black area at the bottom of the device:
Unsurprisingly, holding the device with the battery cover off and getting as much of my hand in contact with the insulated black surface of antenna as I can (something you wouldn’t ever do in regular use), I can make it drop as much as 21 dB. That's just an example of how getting super close to the radiative surface will attenuate signal - iPhone 4 style. We went through the usual gamut of tests and found that the Torch doesn't drop lots of signal, rather sticking to normal levels of around 15 dB cupped as tightly as possible with the back case on.
| Signal Attenuation Comparison in dB - Lower is Better | |||||||
| Cupping Tightly | Holding Naturally | On an Open Palm | |||||
| BlackBerry Torch | 15.9 | 7.1 | 3.7 | ||||
| Dell Streak | 14.0 | 8.7 | 4.0 | ||||
| Droid X | 15.0 | 5.1 | 4.5 | ||||
| iPhone 4 | 24.6 | 19.8 | 9.2 | ||||
| iPhone 3GS | 14.3 | 1.9 | 0.2 | ||||
| HTC Nexus One | 17.7 | 10.7 | 6.7 | ||||
As an aside, remember that you can quickly change the bar visualizations to numerical strength in dBm and back by holding alt and typing n m l l on the keyboard.
Like other BlackBerries, strength doesn’t go above -70 dBm on UMTS, to see higher signal power, you have to switch to 2G for some reason.

WiFi Performance
Because the BlackBerry browser still doesn't open PDF files directly, and we've been using an 87 MB PDF loaded over WiFi and stored locally to test performance, I had to get a bit creative.
I've shared my love for the "yes" unix command before, and I'll share it again. It's a magical tool that simply prints "y" and a newline. Pipe yes to /dev/null, and you've got an instant CPU benchmark. Pipe it to a text file, you've got a disk benchmark. Do it for a while, and you'll have a positively gigantic file. Did I mention it's also compressible?
For this test, I generated a similar size file using "yes", hosted it like I would the PDF, and loaded it in the BlackBerry browser. Note that the BlackBerry doesn't seem to immediately render the page until the file is fully loaded, as a result we're getting basically the entire WiFi subsystem here, not just how fast the browser loads.
The Torch supports 802.11b/g/n, and I saw it handshake and negotiate at 65 megabits/s with my Airport Extreme. That's just under the usual 72 megabits/s I've seen for 802.11n smartphones. In the test itself, average data rate was a consistent 9.8 megabits/s.
Range on the Torch is almost exactly the same as the other smartphones I've tested, I can make it all the way to the street before losing signal from my AP. That's the same as the Droid X and iPhone 4. It's interesting that the BlackBerry BIS link takes a bit of time to switch to WiFi - it seems like it really wants better signal to hop on, than to hop off. For example, the BlackBerry would join at -7 (RSSI), and hold on to the connection until signal was at -8 (RSSI).

RIM's release of this at price parity with the much more advanced Samsung phone indicates that they're more interested in gouging their captive user base than advancing their platform.Sivan - Wednesday, September 1, 2010 - link
I don't full agree with the dichotomy of business vs. consumer mapping onto keyboard vs. touch form factors.Even Brian notes how easy it is to use the keyboard and trackpad instead of the touchscreen. A lot of users value this ease of use especially for messaging or interacting with the device efficiently. Those are not necessarily business users. A touchscreen is not a requirement for a fun BlackBerry, I'd argue that just making BlackBerry 6 available on the venerable Bold line would make most BlackBerry users very happy.
That form factor is also much more battery efficient, the smaller screen (no need for touch) as well as more internal space for a battery, and the immediately availability of the keyboard the trackpad are the small details that make the traditional BlackBerry appealing regardless of whether one is a business user or not.

What are the other devices promised for BB OS 6 upgrades?deputc26 - Wednesday, September 1, 2010 - link
I believe the OS version should read 2.2 not 2.1King Krapp - Thursday, September 2, 2010 - link

Anand,Why didn't you install the Youtube player off the app world.
i'm on a 9700 Bold And I never open youtube links directly in the browser its all done by the app.
Also it would be cool if you could do a browser test with Opera Mini since most people use this over the default browser.

This new blackberry phone really doesnt sound like much of an improvement over older BB phones...With phones avaialble like the Droid G1 or the Droid X I dont understand why anyone would want to own a Blackberry unless security is the main concern. I got my Bold 9000 because back then, it was one of the very few phones that had such a nice keyboard and looked so professional and pleasing.
Now, Droid phones are so much better in just about every way IMHO. The #1 reason for this, is hacks.... What can possibly beat playing GBA, SEGA, SNES and other older console games on your phone with perfect speed, sound and great controls via a full featured keyboard and WASD buttons? And if that's not enough, you can install thousand of other nifty apps, where the number of these apps will only increase becuase developing for Droid will in the near future be as easy as developing for Linux if it isnt that way already!
Android is every geeks dream, and I cant see Apple or Blackberry RIM even touching this wonderful platform when it comes to sheer fun factor and the multitude of possiblities. Yes, I am an Android fanboy, and iPhone and Blackberry should just go in a quiet dark corner, curl up in a fetal position and just.....die....

You had a complaint about a lack of easy 2G/3G switch on the CDMA Android devices. I don't think this is a real issue due to how CDMA 3G works. It's the same radio in a similar operation mode, so it's not like GSM where there's an entire different radio being fired up when you use 3G. The battery savings are not likely to be notable.strikeback03 - Friday, September 3, 2010 - link
In looking for ways to improve the battery life of my HTC Diamond, I found lots of people saying that the constant switching between 3G and 1x is what caused the excessive battery usage. Though in admittedly limited testing I didn't see a difference.I would imagine you can get a widget for Android to lock the device in 2G mode, should you need that functionality.
