Multiple email boxes and downloading periodically

[Guest iondy]

Hi folks,

I have my Kaiser setup with 4 mailboxes (2 imap, 2 pop3), and all are set to automatically check every 30 mins. I do not want to leave my data on all the time (trying to have a battery that lasts a day at least) so I use the registry tweak to disconnect after 1 minute. Now in theory, every 30 mins it should connect to HSDPA and check all four mail boxes then disconnect. In practice it is connecting to HSDPA every few minutes and checking 1 mailbox, then a few minutes later another, and so on. It checks each mailbox every 30 mins but not all at the same time.

I have gone into all the settings for each mailbox, one immediately after the next, and changed how often it is checked thinking it may be checked every 30 mins from the point set, but still it does the same. Very annoying.

Anyone got any clues or experiencing the same thing?? ;)

Try turning it off and then restarting it. It should then check them one after the other. I think one minute disconnect may be too little for each one though let alone all of them.

Also passive GPRS connection doesnt use much battery at all.

Good thinking, for some reason I didn't do that. lol. The 1 minute disconnect is 1 minute of inactivity so should be fine.

So to use passive GPRS I just tell the phone to not use 3G?

GPRS is a data carrier piggybacked on top of the voice transmission spectum; if there's no data exchange, there's no appreciable hit on battery life over and above the phone connection.

3G is a different matter; 3G is an inherently weaker signal needing a higher powered receiver state; it also has much poorer persistence through obstacles, so your phone will spend a lot more time in a higher power search mode swtching between GPRS and 3G.

For this reason it makes sense to constrain the connection to GPRS, either using the Phone/OPtions/Band menu, or a 3rd party switcher such as Bandswitch. There is a 3G on/off setting in some versions of Comm Manager, but some people have reported that it doesn't work reliably, and the 3G connections restarts.

For email polling, unless you are receiving many, many messages GPRS is quite sufficient. Most of the download time is connection establishment and credential checking rather than actual download. If doing more consistent Browsing, then a switch to 3G/HSDPA is preferable, but for other times, leave the GPRS connection live.

Wow, thanks. Back to GSM and GPRS it is then. Lets see how much better my battery life is. ;)
