wouldn't push INCREASE battery life since the iPhone doesn't have to pull the server every so often?
 
wouldn't push INCREASE battery life since the iPhone doesn't have to pull the server every so often?

Good question. Makes sense to me.....

If you look at the 'Push' Settings screen, it says under 'Fetch':
"For better battery life, fetch less frequently."
 
It is funny that there are no Blackberries on the list there. I just came from a Curve. It isn't 3G, but I forgot my charger once on a weekend trip and was able to stretch the battery four days until I got home. I never had to worry about it on a regular basis.

I feel like I have to take it into consideration now that I could use the battery up in one day. Kind of a bummer, but I'll give it time to calibrate or whatever and see what it's like in a week or two.
 
It really makes you wonder what will happen when Infineon ships their 65nm 61x series baseband chips in the 2nd half of 2009. They're touting a dramatic reduction in energy consumption, so we'll see. I wouldn't be surprised to get a 3+ hour bump in battery life - 8 hrs talk time on 3G and 15 on 2G. You will defiantly be able to get a day's worth of of usage out of the phone.

No, because it has to activate the connection every time you get a single message. If you get messages every few minutes throughout the day like I do, your connection will remain active all day, dramatically reducing battery life.

Polling every 15 minutes saves battery life because it allows your connection to go idle and the hardware to go into standby.

How? How could push email possibly strike you as being a battery saver?
If you look at the 'Push' Settings screen, it says under 'Fetch':

Exactly. Push email fetches the most frequently.

If you get 100 messages an hour, push connects 100 times an hour. Regular polling will connect four times an hour. You do the math.

But if you only get a few emails or 5-10 per day- wouldn't Push email then use less battery life?

That's because there is currently no 3G blackberry being sold. The 8900 is slated to be the first.

That is, unless you count the CDMA Blackberries, but I've used those, and my experience is that they don't compete much in terms of battery life.

If you only get a few emails per day, there's not really a point to using push email. What would use the least battery life, if that's your concern, is manual polling.

Push technology is meant to get as close as possible to real-time delivery of email--but it's generally useless, because it can't do anything about the other links in the delivery chain. If it weren't for the fact that the iPhone doesn't support one-minute polling as a setting, it would be totally worthless. No one professionally relies on an email coming 30 seconds sooner. If something is critical for real time, use real time communication. You're holding a telephone, after all.

It's a buzzword, basically.
 
dont get it

Im still confused about the "push" thing. How come my blackberry curve which is "push" would last me 2-3 days on one charge getting about 20-30 emails a day from my work email and the iphone today with only push running (wasnt playing any games or f'n around) only lasted from 8am-6pm and I just got the 20% low battery warning

Usage-

3hours 34 minutes
standby - 9 hours

Battery life across all devices seem to vary. My first BB Pearl would run forever without a charge. My latest can't even get through a day sometimes.
 
my battery of the 3G already died twice in the last 2 days after using it for like 4 hours each time, its kinda frustrating really
 
I feel like I can actually watch my battery gauge go down on my new 3G. This thing sucks juice like my old 1970 Boss 429 Mustang! I usually left my wi fi on on my old 2G and the battery would last a couple of days when doing routine tasks, but after a couple of days of use with my new 3G with wi fi and 3G turned on it drains in a few hours of medium use, bummer.... :eek:
 
I know this is referring to the iPhone 3G, but I've also noticed that the battery life in my iPod Touch has had a significant decrease since installing the 2.0 firmware.
 
It's on my desk at work now because I have the iphone but I believe it was the 8310 curve
That's a 2G device. The battery issues don't have anything to do with push itself, but the power-hungry nature of a 3G radio.

Welcome to the battery life of 3G devices. Now you see why Apple didn't do it originally, and why some of us would have preferred other features to a 3G radio. That's especially true given AT&T's pathetic 3G network, which, despite "upgrades" and press releases, to this day, living adjacent to Silicon Valley itself, I can't get decent, reliable 3G service, even in the city.
 
I'm not assuming anything. I was asking for a citation for his/her comment. I didn't make any statements regarding either phone's battery.

What are you talking about? :confused:

I thought I read some anecdotal reports that confirmed that EDGE battery life of new iPhone is better than original iPhone. I have no idea where I read it, otherwise I'd look for a link.

How's that for confirmation? You can say that some anonymous MR member thought he read somewhere on the internet that it was really true. And you can quote me on that! ;)

Ahhh, my bad, i forgot the curve wasn't 3g, I think the "bold" will be the first BB on att to have 3g

3G and Wifi on all day

Not sure how, but 10% warning came up at the 6 hour mark and it lasted another 2 hours after that

I think the battery indicator is not well calibrated
