Apple's iPhone: The Future is Here

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 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.
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

Except of course for the keyboard.If he unveiled the thing, it would have to be as a small laptop.

Anand, I never got through your iPhone review...because everything I read is basically Blackberry this, Blackberry that. Just so that you know, not all your readers like/own/used Blackberries, and have found other replacements that suit us more besides a Blackberry (i.e E61). Yes, I know you love your BB's, but hope you can rename your article to reflect the review that you wrote. Nothing wrong with it... but reading your article gave me no basis of which to refer to, hence stopped reading it after a few pages.aGoGo - Wednesday, July 4, 2007 - link
Exactly,I used BB 8700, 8100, 8300 and 8800.. all of them suck, i have to admit that the RIM makes the best "stupid-proof" devices, that can enable you connect to your work email through BES, other than that, every single feature sucks.
I'm using the Imate Jasjar (HTC Universal) and it can do every single thing the iPhone can do, without the cute looking UI, people wanna use things, not look at them, how many of you are still using Aero glass and DreamScene? Every single person disabled them after one week.

You can catch bits of Anand's gigantic house as well as his face reflected back in the metallic part of some of the iPhone photos.plinden - Tuesday, July 3, 2007 - link
Actually, http://www.apple.com/iphone/specs.html">here, Apple does claim "up to 6 hours" internet time, so what you're seeing is in line with Apple's claims.
Yes, I do like my Apple products (3 Macs and two iPods) but I've always taken the battery life claims with a large pinch of salt.

I know exactly what you're saying; battery life on the MacBook Pro is no where near Apple's 6-hour claims; I'd be lucky to get 2.5 hours of real work on mine.Thanks for the correction, I too was shocked to see it actually lasted 6 hours on WiFi. I'm doing some more tests now looking closer at its battery life, so you may see a follow-up article in the near future.
Take care,
Anand

Looks nice, but too big for me. If they can build one around something more like a 2.25" screen that would be sweet.Also on the next to last page there is a picture missing of the screen you get to unlock the phone.
Anand Lal Shimpi - Tuesday, July 3, 2007 - link
Agreed. An iPhone mini could be very interesting but I'm not sure how the keyboard would work out. And I've added the missing image, thanks for the heads up :)Take care,
Anand

I had to go through this review for a paper I was writing for school, and I came across this comment. In 2015... how times have changed :)aGoGo - Tuesday, July 3, 2007 - link
Blackberry Curve and Blackjack?there are better phones to use, how about the HTC Universal? Nokia N95? SE P990i? HTC Athena?
I really don't know how much this damn thing is gonna cost if it's unlocked? $1000?
