How to limit HSDPA ramping

[viperx]

Hi all. I was wondering whether anyone had any tricks to stop the PDA from using HSDPA unnecessarily. I find if I'm logged onto MSN all day, with just UTMS the battery would last probably 12 hours or so, but if I enable HSDPA it would clean out the battery in less than 5 hours.

MSN can't possibly require that much bandwidth. Is it possible to limit the phone from changing to HSDPA unless the bandwidth is actually required (i.e. when I connect my laptop to if for internet)

I use a dopod d810 in Australia with optus.

Thanks.

If you don't need 3G, switch the phone to GSM, which would use EDGE/GPRS, or use tools such as bandswitch etc. If you want to completely stopped data connecting by itself, try nodata.

Also, with some service provider, if the phone is connected to HSDPA, my incoming calls get sent to voicemail. If it is in normal 3G mode the call comes through. This has been a problem in many areas. As the last poster pointed out, Bandswitch can disable HSDPA so that 3G is the default mode. Since I don't have an unlimited data plan, I just change the band to GSM and use Edge unless I have to download big web pages or use the Video phone, then I switch to WCDMA mode.

Problem is, I use WCDMA all the time. I connect my laptop to the internet through my PDA. At these times the HSDPA is greatly valued. However, when I'm not and just want MSN messenger on my PDA, well, its a great battery drainer for no good reason.

At the moment I'm getting around this by turning HSDPA back on when I use the laptop and then off again when I don't so it just uses UTMS. However this is pretty annoying having to reset it every time.

Does bandswitching between GPRS and HSDPA require reset?

My carrier - 'MY MAXIS' is somewhat smart. They usually kick you out of HSDPA Network whenever you are not consuming large amount of bandwidth. The phone automatically switches to 3G , but then you are still connected. Then it will switch back to HSDPA whenever there is a sudden burst of data or so. Smart way of conserving HSDPA slots.

I don't think you can limit HSDPA bandwidth or so. Once its connected , its connected. It has nothing got to do with battery. Its just the power consumption. You have no choice but to disable the HSDPA module , so that it does not drain the battery a lot. Limiting bandwidth does not work. HSDPA/UMTS drains a lot of power.

Mine does that too... drop down from HSDPA to UTMS. But the difference between having HSDPA enabled and disabled in terms of battery life is like a third.

Its because if you enable it. It connects to HSDPA , hence it uses up more battery power. HSDPA loves to drain your battery life. This is why , you should switch to EDGE/GPRS whenever you are in mobile and switch it back to 3G whenever you wish to use it as a modem. You dont have any other choices ,mate !
