Power management is about fine tuning 1001 things and is something every competent team keeps improving until sales start and beyond.

That’s^ the key thing here. Compared to a battery powered device with similar, available functions… not any other POP (plain old phone :) )

I have used a Motorola iDEN handset exclusively for over 8 years now. With its always on TCP/IP connection battery life for even the best models is about a day and a half… You adapt very easily to making sure you plug into a nightstand charger every night. It's that "half day" that will get you. More often than not it also happens to be a most criticle day. :eek:

Because of this increased charging frequency more chargers will be sold. Adding to what Quim mentioned earlier, it would be nice if someone offered a drop in, nightstand charging station that had onboard Bose “Wave” speakers and looked more or less like a traditional clock radio.

The bad news sir is that I got your daughter pregnant…

The good news is that we were able to live stream a video of the event using my fully charged N900. :)

:p

don't the new n series come with a battery saver profile, ive got on on the n79

Re: N900 battery life

I've done some reading and as the good General explained the cpu is much more power efficient than the one in our n8x0's.

BUT

Even if we always talk about the average consumer I still seriously doubt that the average consumer will go for this... Much more we will see it in the hands of people that, like us, appreciate the beauty of a full blown linux distro in our pocket.

With users like us the race to idle will be very hard to win for any cpu :) Seriously, even if the cpu is efficient we still have a giant backlighted screen and a handfull of (always on connected) apps.

I'd like to see how much time it gets on streaming video. If the optimizations are well implemented it should last at least as much as the (less efficient, bigger battery) ancestors.

To be serious if I use it seriously I don't get more than a day out of my n800 either especially tethered via bluetooth.

We'll just have to wait and see if they managed to optimize enough to account for 200 mA less and 3g consumption.

Wow, a Mugen extended capacity battery combined with a higher cover plate (ala the N810 option) and the N900 will be approaching cubelar dimensions!! :eek:

I'm guessing here:
3G connected, Joiku Spot transmitting, streaming video with full brightness & max volume, GPS tracking on, accelerometer Step Counter on (you're moving), push notifications & Skype & IM client & pings all on at max occurrence rate, .....am I missing anything?
.
Older battery?
.
Sounds like a bench test.

Aww that kills augmented reality apps.

Nah, with Joiku Spot on, i got 60mins. :p

Walk to station with IM and Twitter pings while streaming or downloading podcasts with bluetooth on, send a few texts, read rss feeds, emails and load a few web pages. Battery was nearly done with by the time i got to work.

Took me about 3 days to decide i need an E71. :D

Re: N900 battery life

Downloading podcasts is probablly what killed the battery. :p

Oh, I hear you there. I shake my head when I see other dads doing it, but then I do it myself and don't even notice.

It is strange to me that you use a laptop at work. It seems strange that you think of the office when you look at your laptop. But I get the feeling that is "normal" these days.

Make sure to share the IKEA catalogue, apparently qwerty12 is trying desperately to get it.
