Battery Life

BlackBerry has long held a pretty established reputation for battery life. I was obviously excited to put the Torch through the usual suite of battery life tests we run on all smartphones and see how it stood up to the competition.

For browsing battery life, we load a suite of pages on a continual loop on a special page that emulates normal browsing on the browser and prevent the display from going to sleep. Brightness is set to 50% on the device. For cellular data, WiFi and GPS are disabled. For WiFi, the cellular radio is left on and GPS is off. 

For calls, we establish a call, play music on both ends, and wait for the device to shut itself off. The results weren't what I was expecting:

The Torch does a surprisingly good job on WiFi, coming close to besting the iPhone 4. That's pretty much where it stops being spectacular. Call times aren't quite as good as I had hoped, though they're admittedly above the 5.8 hours of advertised UMTS (3G) call time, so we do in fact exceed what RIM advertises. They don't publish a 3G web browsing battery life estimate, but again the Torch is middling, right with the iPhone 3GS. 

I'm a bit surprised the Torch didn't fare better considering its slower than average CPU. That said, if the Marvell SoC is still 65nm, we're going to really see 45nm parts pull ahead of BlackBerry that simply do more for less power.

    Rim needs two different BB lines to meet the needs of the two different types of customers they are selling to. They should have a BlackBerry Professional version of there os for corporate clients and then a "fun" version to sell to the average consumer. These two os's only need differ on a few security points and each gets a different ui, one to look business like and one to look flashy and bright. Underneath they would be the same os and run the same apps. Their current middle of the road, one size fits all approach is turning all customers away.

    Add in some decent hardware and you would have a competitive BB again. Two year old hardware specs impress nobody.

    that's what themes are for...

    RIM just needs to work on better tools for developers since what they've managed to do on the business level is second to none and I feel the overall improvement of OS 6 has done just enough to grab enough of the spotlight to be fresh yet familiar without being burdened by the lower specs that have dogged it since the its release.
    There are still quirks in the OS 6 model that needs addressing such as in the social feeds but nothing that can't be solved via updates and UI changes. OS 6 has thrown away utilitarian menus and brought it up to speed with the other Operating systems. It hasn't leaped over like a triple axel but it's more like a combination of moves that will culminate in a much more successful Blackberry phone in the eyes of the average consumer, hopefully dispelling some of the noise that RIM can't do a touchscreen phone to save themselves.

    I'm glad anandtech have finally covered this phone. Good or bad you can rely on these guys for great technical review without putting in ridiculous remarks or bias towards a product that reviews like engadget have seemingly perfected.

    I am disapointed that Acanac fell into the Apple marketing trap which is PPI. Who cares about PPI? Do you really think that it's better to have a 1" 320x480 display than a 4" 480x800? The first one have higher PPI.
    Apple started to talk about PPI (even before pixel count) when they realized that the competition was going with larger displays. Larger display, with the same resolution, means lower PPI, even if it's better.
    What looks sharp is not PPI. It's pixel count. Just hold your 4" 480x800 farther away if you think that pixels are too big. A 1x1 pixel 1000000000000 PPI display is useless.
    So please, stop making graphs about the useless metric which is PPI and start comparing what we actually care about: brightness, size, resolution, etc.

    Have you actually looked at the iPhone 4 display. It really is quite fantastic. And especially since this review is about the Torch, your display size argument is pointless since the torch is both physically smaller and lower resolution. The point they were making is that the Torch display, while not bad, really doesn't stack up with the current generation of devices.

    The iPhone 4 display is one of the best, I agree. Why? Because it has the highest resolution. The PPI have nothing to do with that. The iPhone display would be even better if it was larger, even if that would mean lower PPI.
    Of course, the phone would probably get larger too, which is a downside.
    What I mean is that the highest PPI is never, or at least should never be an priority for any consumer.
    The iPhone display would suck if it was 2" instead of 3.5".

    He is right, though -- nobody cared about PPI before Apple started their marketing. Now suddenly it's the standard by which screens are judged. Weird.

    I have looked at the iPhone4 screen and while it's nice, it's nowhere near as nice as all the marketing and buzz make it out to be. I cannot read all that sharp yet incredibly tiny web page text without a magnifying glass. I'd say it's about 20% as nice as all the hype. A large screen that lets you see more of your web pages in an actually readable way is certainly nice, too, probably a little bit nicer -- and yet for some reason the iPhone4 gets a pass on this readability issue from all the reviewers, just as Apple hoped. Honestly, having seen the iPhone4 screen, its main benefit is in browsing photos, which look really smooth, but who uses their phone mainly for browsing photos? Not that many people, I'm sure.

    I believe that the whole PPI thing came about because Steve Jobs realized his 320x480 screen was getting long in the tooth compared to other phones but a) didn't want to change the dimensions of the current iPhone and b) wanted to make the existing iPhone layout and apps easy to port by simply doubling the screen resolution. So he pushed the PPI angle hard and zombie reviewers got in line.

    Great post.

    Lots of people care about PPI, just not so much on smartphones.

    I hope Apple's obsession with PPI and the Retina Display pushes the trend into *laptops,* so I can finally stop seeing 15.6" laptops with 1366x768 horrible LCDs.

    I'm confused by conflicting statements in this review. Half way through the conclusion he says, "I’ve described the Torch as anywhere from a quarter to a half generation behind - I think that’s the best way to describe performance." But, the last sentence is, "The Torch is what RIM should have launched years ago in their stead."

    Combined with the fact that the Torch both statistically and measured performance wise is no better than the iPhone 3GS or other last-gen phones I don't get the quarter to half generation behind comment.

    I'm not sure whether even hardcore RIM users are going to be able to accept weak attempt at getting up-to-date.

    A very balanced review. This device isn't for techno snobs or people who like to show off apps - it's still a business communication device. While anecdotal, I know a number of BB users which looked at Apple and Android but decided to go with the Torch instead. Without exception they are happy as it gives them the new functionality they wanted but without leaving the BB strengths and advantages behind.
