PDAs, Cellphones, Wireless When talking about the webOS, one of the main complaints is often that the operating system feels sluggish, especially considering the Pre has the same hardware as the iPhone 3GS. At a webOS Developer Event in London, Ben Galbraith and Dion Almaer (the Mozilla guys who joined Palm) talked about why this is the case, and hinted that it will be fixed sooner rather than later. They also addressed The One Question: will Palm ever open source the webOS?

battery life

According to what I've read, the iphone battery lasts 2 to 3 days, and less than 10 hours when heavily used. The batteries die after 2 to 3 years of use and can not be replaced.
I take longer battery life over better 3D effect on my mobile phone any day.

I have a friend with the original iPhone. No battery problems yet. I call FUD.

[edit]

Actually I have two friends with the original, no problems.

iPhone 3Gs
Talk time: Up to 5 hours on 3G, up to 12 hours on 2G3
Standby time: Up to 300 hours

Palm pre
5 hours talk / 250 hours standby (maximum)

And this is official estimate. Every reviews I read made negative comments on the Palm pre battery life.

And for some reason, it is harder to find battery life specs for the palm pre than the iPhone. Google only give article about "how to improve Palm pre battery life" when you are searching for specs.

I don't know where they dug that little gem up but I bought a Pre abount a month and a half ago and I've never seen anything remotely close to that in battery life. I would estimate it more at 2-2.5 hours talk time and *MAYBE* 48 hours standby on a lucky day (if all features are turned off). I suppose you could possibly get 50 - 60 hours standby if you keep the phone in "Airplane Mode" but that sort of defeats the purpose of having a cell phone now doesn't it.

every report indicates that the Pre doesn't last as long as an iPhone for battery life.

You can also bring in an iPhone to any Apple store and get the battery replaced over the counter.

In fact, the Pre likely uses way more battery power by using it's CPU all the time instead of the GPU.

I own a Pre. The battery life does suck, and I would doubt it lasts as long as an iPhone. But I would venture to guess that the problem lies deeper than a GPU vs. CPU processing issue. As the pre matures and its background services, libraries and apps are better optimized, battery life will likely increase. My Pre already lasts slightly longer with WebOS 1.2.x than it did with prior releases. I hope this trend will continue with each WebOS update.

I'm not so sure about this. Right now, the GPU sits relatively idle and consumes an unknown baseline of energy while the CPU manages graphics calculations. Enabling the GPU would just transfer those graphics calculations from the CPU to the GPU--thereby raising the amount of energy consumed by the GPU. In the end, you're merely shifting power burden from one component to another. The real question is whether or not the GPU is more power efficient than the CPU for these calculations.

In practice, GPUs tend to consume more energy than CPUs. You also need to keep in mind that the GPU and CPU will now be active simultaneously. Performance and latency issues will improve, but battery life may not.

As a pre user, however, I *reallllly* hope it does improve.

And that will be even worse if they use the GPU more in my opinion.

Indeed, but that is not equal to be able to change the battery yourself. I have a phone that last easily 2 weeks with normal usage. I can not afford to miss a call, so I always have a battery replacement in my pocket. With the iPhone, when it's exhausted, you can not even ask a friend for his battery. You can put your sim card in his phone (I hope you can) but you don't have your data (phone numbers, etc..). A phone with no battery is useless. For me, removable batteries is a must, and I can not understand why the iPhone can't have that in 2009. What did they think? Do they charge for replacing it in the store? I can not even find a store in my town.
