how much does your battery last for ? 2 - 4 days online ?
 
Staying online with music playing and maybe some application, and 2 widges that consumes energy : facebook widget and foreca weather widget makes my battery lasts for about 2 hours no more no less,
now here is what wikipedia says about n900's battery :

Battery and SIM

Battery life for the device may change with time due to ongoing development and attempts to optimize power management through firmware updates. In a press release[62] Nokia stated they are aiming at "one day of full usage"[63] or "Always online : Up to 2-4 days (TCP/IP connected)" and "Active online usage: Up to 1+ day". Early reports from users range from 12 hours (Wi-Fi on, web browsing, video and some GPS),[64][65] to about 2 days online but not used continuously.[66] The value appears to be highly dependent on the user's choice of background software, active desktop widgets, IM and email polling, as well as mobile network signal quality (especially 3G) and in some cases, software bugs. Nokia reported talk times are around 9 hours with GSM and 5 hours with 3G.[67] Battery life can be extended significantly by switching off GPS/A-GPS, WiFi, and Bluetooth and by replacing 3G by 2G / GPRS.

While previous Internet Tablets used larger batteries (1500 mAh compared with the N900's 1320 mAh), they are based on a less efficient microprocessor. Typical battery time for the Nokia N810 is around 7 hours of continuous full usage, display and Wi-Fi on. In principle, On N900 figures are expected to be much higher. Third party extended batteries up to 2400 mAh capacity are available for the N900.[68]
users reported 12 hours wifi on !

That is true , mine lasts about 2 days WiFi ON if I dont play too much :)

I think your problem is the facebook widget , A lot of people were complaining that it is not optimized and consumes battery all the time , I suggest you remove it and check again

Wifi may be on, but is it connected to wifi router? My battery lasts about 6-8 hours if connected to wifi. I suppose I have a few widgets, etc. If I turn wifi off or disconnect, it will last more than one day.

there are many battery optimization threads you might want to check out (with tweaks ranging from changing swap with swappolube, adjusting overclock and voltage, using autodisconnect, etc) but don't expect miracles - while my device can just sit around on wifi for 2 days checking email and updating widgets (only about 6 to 8 hours of the same on 3g), I get maybe 4 hours active web surfing max, less if things like bluetooth and gps are enabled, and about 30 minutes of skype video calling, which is the fastest battery drainer ive come across.

the idea of this thread is to collect the members experiences with battery life/day, i remember that i used to charg the phone once/day when i was lightly using it but now im using it a bit more plus games and emulators so im charging it twice/day (once through the day and once while im sleeping)

Re: how much does your battery last for ? 2 - 4 days online ?
 
since im using my own custom battery i charge every other day, but i am using my phone very heavily, i really have to use it non stop if i want to use the battery in one day.
Any my new 2763mAh battery really gives me peace of mind that i don't have to limit myself from using my phone when i know i will not be near a charger for some time.
I can remember when i got it i really hated the fact that i could use up the battery pretty "quick", and that's why i got on getting battery's and start making my own battery since i don't want to pay 95$+ for the mugen battery.

My high usage includes always having my custom brightness at level 3 (= between 4 & 5 without custom brightness)

Oh damn. Ah, man. This really, like, sucks. Boo hoo. I mean, like, people, on a forum, discussing. This really blows.

I can get about 1 hour of 3G web, 1 hour music, maybe 20 minutes of either a game or a video. Brightness level 3, ulv power kernel profile clocked at 600 to 850. Wifi completely disabled, internet connection (via 3G) only on when I need it.

My battery last approx 2hrs max. N900 is my main phone so i use it heavily. I have noticed that recently my battery has been dying more than it used to. A few months back i used to get 4hrs heavy usuage but now its 2hrs or so if im lucky.

I think my actual battery is dying because it is now only 1281 (mAh) at full capacity?

My wifi is always on, my 4 desktops are riddled with widgets. I'm thinking the battery drain has something to do with 'Desktop Command Widget' but not sure?

Does anyone know an application i can use to invesitgate battery drainage.

Is this normal?

Thanks

nathaneous : you can use battery-eye and htop, some users here prefer conky

battery-eye offers some statistics. Here's mine:

I keep wi-fi always on, btw.

My battery lasts 24-36hrs on Wi-Fi (connected, collecting mail every 15 minutes, Skype/GChat for at least half that time, OM-Weather widget running). On GPRS, it lasts maybe 5-6hrs...

I use Titan's Power Kernel and some other tweaks to paging and stuff, and 2g-3g switcher, with PR1.3 (which itself made a huge difference to battery life).

@lunatik does battery eye identify what could be causing drainage?

thanks

Thanks mate, which one of those apps would help me identify app or widget thats causin drainage? Never heard of htop is that abbreviated for something?

i have 2 days (atleast, 3 days max rarely) on WiFi with SIP/GV registered and with no widgets.

moderate use: a tyipiical day in teh life of my n900:

unplug from charger at 8:00am
+- 30 of min skype calling,
+- 15 min of 3G calling
Wifi all day (only conected at home or office)
3G data not conected
+- 20 min MP3 audio
1 x sync

i get 7 hrs (some times less some times more)
wifi i think kills my battery as i talk more on weekends and am not connected to a wifi and my battery lasts 12+ hrs.

htop is available frm the repospls download

i use htop its in repos, you can see whats consuming the cpu and whats consuming the memory..never used conky but it gives you graphical details of the running applications

Sometimes wifi kills your battery if the router doesnt support power saving modes. I have Dlink one. When i connect to it my battery drains in few hours. But if i connect to regular router battery lasts ~ 2 - 3 days

hmm, in this theory does ad-hoc from a laptop drains more ?

htop is just htop. It's in the repositories, and can be found on the downloads part of this site.

As for this thread, I tend to have my N900 last one day with a couple of hours of WiFi internet use, around a day and a half with very little use. I use Advanced Interface Switcher instead of WiFi Switcher, but it does the same thing - unloads the wifi driver - when I'm not on wifi, so that helps. I'm on stock battery. Heavy use of constant heavy multitasking/gaming/browsing will eat battery within a few hours. I try not to have too many things eating battery in the background, but *shrug*. I may have some I just don't know about (ones I do know about is SSH server, all the stock stuff, anything Advanced Power and Advanced Interface Switcher uses, shortcutd/proximityd, cl-launcher [I'm not sure how much that does in the background though], and probably a few other things I just don't remember).

This is without the power saving mode for wifi ever set on.

After 29 discharges (> 300 seconds), BatteryEye statistics tells me:
Low use: 3 days 6h 14m
Average use: 1 day 11h 14m
High use: 17 hours 4 minutes.

I am using ~2600 mAh battery-hack.

My 2c:

Last week T-Mobile switched network to new 3G+ generation available in SF Bay Area (3-5MB/sec). I immediately see a boost in battery while N900 idle - http://talk.maemo.org/showthread.php?t=66763 in that day

It jumped from 30h of idle time to more then 50 now. Sometime now I see a full battery bar at night.

Re: how much does your battery last for ? 2 - 4 days online ?
 
The difference between idle and active usage is quite big with me, seems if i don't touch it it might last more than a whole day off the charger somtimes, but with active usage the life might go down to bellow 6 hours, often around 4 and when i'm really out of luck it starts crying after only 2 hours....
