Battery Life

Using the iPhone you already know it's not going to last very long on battery; I didn't have enough time to run the full suite of battery tests, but those that I did run will give you a good idea of what to expect.

The first test is a strict email benchmark. I created a gmail address and signed up to receive all of the latest postings from some of the most popular newsgroups through Google Groups via email. The end result is a mailbox that gets over 5000 messages a day, and a perfect worst case scenario email test.

All three devices were run on the Edge network to be the most balanced, but keep in mind that the Blackjack supports 3G and the iPhone can run over WiFi. Bluetooth was enabled during the test, but remained unpaired with any devices.

The Blackberry Curve was the only device out of the three that could receive emails instantly, and it did so much faster than either the Blackjack or the iPhone. Both the Blackjack and iPhone automatically checked the mailbox at 15 minute intervals, but in actual email download speed the iPhone was clearly faster than the Blackjack.

Battery Life Test - Email

Battery life for email was a clear victory for the Curve, lasting just over a full day doing nothing but checking emails. Keep in mind that all three devices were set to their silent profiles, meaning that the Blackberry was constantly vibrating as it received multiple emails each minute.

The iPhone more than measured up to Apple's own estimated 6 hour battery life during Internet use, lasting 6 hours and 53 minutes. The Blackjack on its standard battery came in last at a bit over 5 hours. From our experience, the extended battery would probably bring the Blackjack up to the iPhone's battery life.

It's important to note that these tests are best case scenario as I'm not walking around town with the phones while testing them, which would be far more stressful on battery life. That being said, the Blackjack and iPhone simply don't cut it for high volume email devices, there's just no replacing the Blackberry. For casual email though, either will work fine.

Our other battery life test is strictly web surfing; we loaded a series of nine web pages stored on a local server and looped the test until the batteries ran down. The screen was left enabled on the Blackjack and iPhone but we couldn't force the Curve to do the same, so its results are slightly inflated by having a screen that went to sleep after the first 30 seconds of use.

Battery Life Test - Web Browsing

This time on WiFi, the iPhone comes in closer to its estimated 6 hour internet battery life. Again, you're looking at best case scenario battery life; watching a lot of videos on YouTube will run the battery down

    Holy Comprehensive Review Batman! That took most of my morning at work, good thing its practically a holiday here already.

    Now my question is:

    How many poop pictures has Anand received from the A-Tech staff?

    Haha
  • Shimmishim - Tuesday, July 3, 2007 - link

    Yes. It was a good read. One of the best reviews of any piece of hardware (computer or consumer related) I've read in a long time.
  • Anand Lal Shimpi - Tuesday, July 3, 2007 - link

    Thanks guys :)

    And no, zero poop-pictures from AT staff.

    Take care,
    Anand

    While not perfect as a product either, Anandtech completely skipped any Palm Treo devices for this comparison. The Treo has done SMS by contact for some time now, just as you have mentioned the iPhone does (I've had it on both the 650p and 750p; I'm sure the new 755p does as well). While I have some issues with Palm support as far as their product goes, I still haven't seen a smartphone that can do better --I blame this at least in part due to carrier wars and desire for control (i.e., crippled Bluetooth, not adding WiFi, so carriers can make you pay for everything through them), rather than blaming cell phone manufacturers.

    There were a number of products I would've liked to have included, but I was very limited by time so I tried to shoot for two of the most popular: the Curve and the Blackjack. I've already dropped Nokia an email but I'll do the same for Palm and see what comes of it :)

    Take care,

    Ya, quite alot of things like that the Treo has done, and done well for a long time now, all that and an open platform. The issue is the latest Treo is, 4 years later, still the same repackaged Treo, with a few minor upgrades. The iPhone is by far the best UI, and that alone will be its saving grace, and its legacy on the industry. A few years from now, REAL smartphone manufacturers will copy the UI and improve everything, and do it cheaply, and on all carriers. That is the best thing about the iPhone.

    Actually, in 4 years, the Treo added Bluetooth (the first 600p didn't have it), EVDO (the iPhone has only EDGE, which has been rated far slower, and slowest when provided by AT&T/Cingular, the single carrier of the iPhone), an SD card slot (600p didn't have one), and several other features.

    As I said, the Treo isn't perfect. And I think the UI of the iPhone is pretty spiffy, plus I'll bet it has the best web browser of any phone on the market. But I don't think I could do without a real (by real I mean tactile) QWERTY keyboard (I rely on text messages for work, since cell reception can be spotty in a reinforced concrete building), I like having EVDO support, and I like the fact that I can choose from Sprint, T-Mobile, Alltel, Verizon, or AT&T Cingular for a Treo (AT&T/Cingular has little or no reception in my work area, so it nixes any thought of an iPhone, and by my understanding, they have a five-year exclusive agreement with Apple). And I can get a Treo for a few hundred less as well.

    I want to like the iPhone. Unfortunately, Apple set conditions of pricing and carrier that mean I'll never find out how good a phone it might really be.

    Not only the Palm Treo, but the Nokia N95, which is just awesome:

    In-built GPS and Navigation Program (over 100+ countries maps)
    5 MP Camera with Zeiss Lens and Optical Zoom, and Video Recording
    Symbian OS
    Plays MP3, video, etc
    Bluetooth, Wi-Fi, USB, TV out
    Quadriband GSM/WCDMA (3G)
    MicroSD Card Reader

    Among many other features.

    The iPhone looks great, but the big gotcha for me is that I routinely use my 8525 to access the internet on my laptop. Can't do that with the iPhone from what I understand.

    As for all the comparisons to Verizon & such, if you look at the total cost of ownership (Verizon's data plan is significantly more expensive), the iPhone is just a few dollars cheaper than the Blackjack w/Verizon.

    I've got a Samsung i720 with verizon... For a "last gen" PDA phone priced at just $100 brand new from verizon when I got it, it's pretty sweet. Admitingly the display isn't quite as good as apples, but as far as functionality it does everything the iPhone does and more. I also appriciate the sliding screen with which reveals a keyboard. There's also the other advanatages I mentioned earlier, i.e. Windows Mobile being open to 3rd party development etc.
