Does anyone leave their phone registered to 2talk or any sip provider all day/everyday?

Interested to see what battery life everyone is getting on what handsets.

Registered via WiFi or 3G? It makes a big difference.

3G of course, can't exactly roam on WiFI.

I get a days life out of my E65 with SIP connected via WiFi. With 3G connected permanently it would be significantly less than that.

The rated 3G talk time of the phone would give a fairly accurate indication of the battery life you will get with a permanent 3G data connection - I think you'd probably be looking at ~4-5 hours tops for most phones.

Running VoIP continually over 3G isn't really something handsets were designed to do, if you do want to do that I think you would certainly want an E71 as it has the biggest capacity battery around.

Just got 5hrs out of my e61 with minmal usage before needing to change batteries.

I'm just giong to setup 2talk to forward calls to my 021 number and make outbound on the 3G when required.  Just means it takes a bit longer to make a call, having to sip register each time.

Cool thing, was when I just walked into the house, instead of registering to 2talk over 3g, it registered to my home asterisk box over wifi (i'm assuming because it discovered the wifi).

Hi-ho,

I've just got the new E66, and it does a couple of days standby with an hour or so talking on WiFi.  The E65 before it seemed to only do about half that.

I can't imagine why you'd want to use 3G for SIP though, the jitter often makes the call a bit cruddy.

The other minor point is that I thought that using VoIP over the 3G data connection was against the TOS for your vodafone connection?  Have to find my contract...

Cheap cheap is why I use it.

If not moving its fine, and even when moving other then getting the odd bit of lag then catchup, its not too bad at all. A hell of a lot better then trying to run shoutcast streams over 3g.

being able to call people with my home caller id is great since I dont want people to get my mobile number. Sadly I will have to give the N95 back soon. One thing i found tho is that not all car chargers are equal. They all make my phone animate the charging and light up if they are flat, but one I have will charge it to full on a hour long drive, the other will barely get 2 bars into it. I can go long enough on the phone with 3g and sip up, but only with the good car charger. The crap one would actually run flatter if I had the phone playing mp3s and 3g up checking emails all the time.

Ay, you're right there on the chargers.

I gave up on the cheap one I got, and went to using an inverter in the car and the real Nokia charger...

I use bluetooth on my E66 quite a bit, for an earpiece and sync to the laptop for calendar etc..

If you've got WiFi, Bluetooth and 3G all turned on and active it can suck through the battery in under a day...

Still, very cool phones...

SIP quality is fine for me in Auckland.

I use it because it is cheaper than my GSM rate, and I only use about 25mb of my 200mb data plan for active sync each month, so why not use the rest on SIP.

The T&C's about SIP just mean that they don't guarantee SIP will work 100%  (due to bandwidth no doubt).

Ok after a couple of weeks, using it registered full time to 2talk kills the battery in about 5-6 hours.

now I'm only using it for when I make outgoing calls.

I have got to find a fast usb charger, my usb charger is so slow.

That may not be so easy, USB ports can only output a certain amount of current and at a certain voltage. 500mA @ 5V?

I've had to give the n95 back :( but I even found when moving that sip on 3g was better then gsm most of the time, which is saying something about the sad state of GSM. I had a hell of a time finding a car charger that was up to the task. I almost bought a real nokia one, I was that desperate. I dont see how they can vary so much and still be sold as suitable for the n95

Back to my telecom phone for voice only now, should really top it up again :(

No-name car chargers can be had for about 20c ea or less when buying container loads at a time, so that should give you an idea of the (lack of) quality control, and the (lack of) consistency across them.
