3G and power consumption

Eric Baines · Joined: 15 Aug 2007 Posts: 35

We have a lot of MS smartphones. Recently, we are getting Mobile 6 devices,
and our mobile phone supplier is providing SIMs that come with 3G sevice (we
are in the UK).

This should be good, but when the phone is able to connect to 3G, the
battery life falls through the floor. Devices that otherwise have a battery
life of 5-10 days go to having a battery life of 12-24 hours.

The phone suppliers won't disable 3G and I don't seem to be able to disable
it on the phone.

Does anyone else experience this problem? Does anyone have any ideas what I
can do to eliminate or reduce the problem?

To Disable 3G
If they're HTC PDA type phones, (Tytn, P3600, etc.), go to Start > Settings
> (Personal) Phone > Band
Set netword type to: GSM
Set GSM/UMTS band to: (900+ 1800)+UMTS(2100) - Correct for T-Mobile and
Orange, not sure about the others.

This gives you GPRS only. You won't really notice any difference in
performance for mobile web sites such as the BBC and downloading email - D/L
large files etc would obviously be slower. It's easy to do and easy to
reverse (just revert the Band settings to Auto).

From what I've read, it's voice calls, rather than data downloading, that
seem to hammer the battery with 3G.

Cheers

Thanks for the answer. It is a Treo 750 so I'll try it and let you know how
it goes.

Thanks again.

Treo 700 Battery Consumption Can anyone with the Treo 700 let me know what the actual battery consumption is? I have one for testing purposes and it seems to me that the battery live is way toooo short. Any info would be very helpful. -- Rob "A disturbing new study finds that studie
