I am curious as to what enables the blackberry 8700G to have a standby time of up to 16 days, and still be able to receive all the emails and pins and sms.
I had a sdk and it would barely last 1.5 days without me touching it.
It heard that the constant conection to the GPRS/EDGE was to blame for the consistent battery drainage.
So my question is, how is the bb able to perform wut it does with such remarkable grace??

Why would you leave it sitting for 16 days. With heavy usage my battery lasts 2 days but I usually charge it each night.

I don't plan on leaving it sitting for that long, I'm just intrigued at the possibility that the device has such capablilities, and other devices aren't even up to par with it.
I just wanted to learn more about the technology behind this marvelous product.
I have searched around, but cudnt find anything. Was hopeing someone in the forums knew something.

What do they mean by "standby"? With a wireless phone standby generally means not making any calls, not receiving any calls, not lighting up the display, not doing anything other than letting the phone sit there and check in with the tower at its regular intervals.

that is correct.

other phones are HORRIBLE at performing in the "standby" mode, such as the MDA available from Tmobile. it would barely last 10hrs albeit you havent touched the device!

My Sidekick 2 didn't last one day uncharged. My first 7100t lasted 10 or more days with light use.

I get a solid two days with moderate usage on TMobile. 16 days sounds like Cingular's 8700 with the extended 1800Mah battery.

I had the 7100t and it would only last two and a half days with moderate usage. I trained the battery properly when it was brand new. Did you have an extended battery to get 10 days?

With moderate usage and verichat running only aim/yahoo...my 8700 will last two days uncharged. I usually charge it overnight.

Two things:

- I don't think the BB chatters much when it's got nothing to do, so the only real drain in this mode hello/keep-alives to the tower. GSM (and thus GPRS) is designed to be very power efficient this way.

- Signal strength makes an enormous difference. At the limits of range from the nearest tower a GSM phone will run its radio at up to 2W at best it will use 1/100 of that power. 2W is a lot to take from a small battery! So it depends on the signal strength where you spend much of your time...

Maybe the sdk needs to chatter more?

There are several features in this device which save power.

Obviously the x-scale processor offers a huge advantage in that department.

Secondly, the device senses the level of ambient light--if you typically use the Blackberry in well lit conditions, you'll be saving power on backlighting...

And you're likely in a very good coverage area. Which obviously reduces the amount of power the transmitter requires.

.

actually i have noticed that it quite the opposite. when it comes to being a WELL lit area, the backlight level rises to the max....

... and I think dims down again when ambient is very bright.

I turned that option off, I found it very annoying especially indoors.

No. I just wasn't using it as much as I use my 7105t now.

Yes, I too find it very annoying, it gets too dark sometimes, and I'm forced to press the power button to max up the brightness.
