Is GPRS used up much power?

---

I keep my brand new XDA2 always connected GRPS to receive instant e-mail?

However, I found that my XDA2 using power very quickly.

In the past, when I used the XDA1, my GPRS plan is not that much so that I can keep it on-line all the time and the phone battery gone out reasonably.

Any thoughts?

Try a longer interval between checking the email. I originally had my XDA set to check every 15 minutes but I could see that it was sapping the battery strength. I dialed it back to once per hour (this is the longest interval you can choose) and I can go a few days at a time this way (depending on how much I use the XDA otherwise).

That means GPRS really consume too much power.

I will adjust setting to an hour.

Thanks a lot.

let me add small comment on this, it's not the 'alway on' that drain the battary, but any type of data traffic . it would be the same if you use CSD line. I'm not sure, but I noticed that phone calls do not consume that much ... maybe coz data traffic uses lot of buffering and errors handling.
