Could someone tell me how long the N900 will continuously play music?

Re: N900 battery life
 

I just rcvd my N900 yesterday, and today spent all day out and about from 7:30am until about 4pm. I'm in software sales, and I used the N900 alot today, basically it replaced my laptop. I spent ~2 hours on Wi-Fi in the morning, T-Mo 3G the rest of the day, downloaded and listened to a few podcasts for about an hour, made several phone calls, used email throughout the day (frequently), and also the browser to check stocks and update salesforce.com.

I had wi-fi interval set to 60 mins, but I forgot to change my MfE setting, so it was pushing mail continuously. Ran the battery down to the red bar at around 4pm. Hope to get some additional battery life by changing MfE to 30mins and wi-fi to Never.

To get a good working days use out of it, I am pretty pleased. I only get a couple hours from my laptop, and its a pain to lug around. I could see the N900 replacing my laptop use substantially.

If Docs to Go ever supports doc editing instead of just viewing, there would be few occasions where I would need a laptop.

And the Nokia DC-11 I have en route from Newegg should provide good insurance for a backup charge when on the road.

Re: N900 battery life
 

I've got my N900 10 days ago.

The battery lasts between 12-24 hours. 12 hours is with heavy usage:

- 2-3 hours surfing
- email check every 5 mins
- wifi scan every 10 mins
- foreca widget (1h interval checks), load applet
- 1h internet radio
- 10 min phone calls (several calls)
- 4-8 photos with flash
- 2-3 mins video recording
- 10h wifi connection
- 2h 3G connection

Usually I am doing about 16-20 hours with a fully charged battery and I am pretty happy with it. After reading this thread I've done some tweaks which will improve battery usage. I think this will help a little more.

With some tweaks and light usage one should be able to do 30+ hours on a full charge.

For me 18 hours with moderate usage is very acceptable. Anything more is a bonus :)

Ya, well screw you lol My N900 wouldn't last more than 6 hours WITHOUT using it. Even turned off the internet connection completely.
Regardless I sent it back to Nokia and they are sending me a new one (at a snails pace I should add).

But I came across someone else with the same issue as me on the Nokia Forums (http://discussions.nokiausa.com/disc...cending&page=2)
Now he also got a replacement unit and the problem persisted! What he eventually did was end up getting a new SIM card and that solved the issue. Weird, right?
So I will have to try that when my replacement N900 gets here but my SIM isn't that old to begin with so who knows.

Just wanted to share for anyone else having horrible battery life and are extremely jealous of people like him above^ lol
Can I ask, are you in the US, using T-Mobile USA?

I don't know why but i feel that charging through the pc's usb make the n900 battery life seem to last longer. Is it because of slow charging?:confused:

Re: N900 battery life
 

I was having issues with the battery but for me it's improving day by day. I moved around my desktop widgets a bit. Removed stuff I didn't really need like the AP News updates.

Since then the battery has been pretty good. I use it quite a lot. Lasts me the day at least. Although I will be getting a spare battery just in case.

I'm not sure what others are on about completely draining the battery will stop the phone from working. It isn't true. My battery has drained several times to the point where pressing the power button doesn't do anything. A couple or so hours later when I do plug it in to the charger, it starts right back up without any issues.

I'm not really that bothered about going round the world in doing xyz to ensure the battery life remains good for more recharge cycles. A new battery is about £26. Hardly much when compared to the cost of the phone for £500. I prefer to use and charge the device how I like it tbh.

well i discover today that running ssh to my remote server and executing htop or forward stuff from the server will drain the battery REALLY fast :)

Up to 22 hours, but under normal usage, probably less. See Tuomas' tests here:
http://tuomas.kulve.fi/blog/2009/11/...ion-ogg-vs-mp3 It sounds like you could actually get better battery life using ffvorbis to play ogg vorbis files than mpgs with the default player... some seriously good optimization work.

It really depends how the battery charger (internal circuitry) detects "full" but it is possible there could be a small difference.

Re: N900 battery life questions, issues, scenarios
 

I use n900 in "always online" mode: SIP+Gtalk+ICQ+OVI XMPP, email check every 5 minutes.

It lasts about 18-24 hours of moderate use on WiFi and just 12 or so on EDGE.

Can this be improved? My old e90 lasts almost similar 40 hours on either WiFi or EDGE, no difference. What's wrong with EDGE on n900? And what is the problem with IMAP IDLE?
