how fast your battery drain?
 

guys my battery just lasts for more or less 10 hours? how about u? does it last the same or longer?
do the theme and the widgets have something to do with the battery drain?

Re: how fast your battery drain?
 

yeah about 10 hours of browsing here

Re: how fast your battery drain?
 

Mine lasted for about 1 hour if I was on continious browsing and about 3 when the phone was normal, changed the battery now it lasts about 12 hours or so with on and off browsing.

Re: how fast your battery drain?
 

damn... today i've unplugged at 8am, and is dead now. it makes < 12h. while working, so was all time idle. Probably I've installed some crap.. last month was 2 days with >30' browsing and couple of calls...

you can also see this thread.

Re: how fast your battery drain?
 

so it seems some craps we install which drain the battery very fast.
i have disabled all the widgets and disabled any monitoring tools i used to use. and i wanna monitor it and see how log in it last

Re: how fast your battery drain?
 

My phone is dying in 6 hours now ever since I put a T-Mobile SIM card in there... I used to be able to get 24 hours moderate usage with WI-Fi on constantly, 36 hours light usage... now it dies in 6 hours on 3G??

I have bluetooth/gps/wi-fi scanning/all that crap turned off, 3/4 of the desktops disabled, only one active widget (calendar), TOR polling SMS at 2min intervals (same as I had before on wi-fi), nokia messaging for one account, and smartreflex enabled. And it dies in 6 hours.

I just bought the phone like one month ago so I don't think the battery is dead... something is ******ed between the SIM card and the phone though.

Re: how fast your battery drain?
 

with powertop you can try to find if something is waking phone up constantly.(power search talk and wiki) e.g. im account skype,msn,googletalk etc might trigger drainage.

Re: how fast your battery drain?
 

guys i want you try this one. it helped me to reduce battery consumption when the device is in standby.

Re: how fast your battery drain?
 

4 hours or so... :(

Re: how fast your battery drain?
 

Ok so if you find googletalk/skype/etc is draining battery what are you going to do?... we're all obviously aware of the fact that doing nothing with the n900 is the best way to increase battery life.

what exactly constitutes "standby" for the device?

Re: how fast your battery drain?
 

my battery? last as long? but i wish it lasted longer?

Re: how fast your battery drain?
 

20 hours (my N900 is only a few weeks old) checking email 8-20 times a day (primarily by WiFi), 2-6 hours of music, with no widgets on the desktop (only shortcuts), with a black desktop background and all components turned off when not in use. Frequent StockThis use (5 times a day) and infrequent GPS use.
At the end of the day I still have plenty of green bar showing.
On the days in which I use iNES or any other game the battery drops much faster.
My notebook computer only gives me 1.25 hours so I'm very happy with the battery life of the N900 so far.

Re: how fast your battery drain?
 

well, after i have uninstalled most of the crap applications i installed in my N900, my battery is up for 2 days and still showing 49%

i sugges all of you to remove all those applications/themes/widgets which are working all the time and cosnume ur battery

Re: how fast your battery drain?
 

My N900 stays up for 2 days.

Re: how fast your battery drain?
 

With loads of widgets and 3G N900 doesn't last long for me. But I'm fine with it as that's a trade-off for the ability to have pocket PC with me.

Re: how fast your battery drain?
 

My battery drains empty in about 12 hours now without using it, it's just 12 hours of standby (GSM and Wifi on). Did a complete reflash (incl emmc) two weeks ago. It makes no difference if I set the max cpu to 600 or 850Mhz

Anyone able to see the problem ??

Re: how fast your battery drain?
 

I get between 24 and 48 hours depending on usage, can be lower if my daughter wants to watch a movie :)

How I got that far:
- no wifi
- no 3G unless needed, so almost always GPRS
- swapiness hack (set to 30)
- overclocked to 500-805MHz and ideal profile

at night, I switch the n900 offline (flight mode).

During the day, I have 4 mail accounts checked every 15min, 2 IM accounts online and calendar/contacts synce every hour. Some websurfing, mail reading, 1 or 2 phone calls and some chat sessions.

Re: how fast your battery drain?
 

I have noticed a similar decrease in battery life that has not been addressed by a reflash of image and eMMC. Haven't been able to track down what the issue is with this huge difference in power dissipation.

Re: how fast your battery drain?
 

About 3 days with medium use using the swampiness changes, kiiling the indexing, killing apt update checking and clocked for 250Mhz-1GHz.

Hard usage (n64 games all full 1ghz) about 4-6 hours of play time.

Re: how fast your battery drain?
 

i get under a day. :(

Re: how fast your battery drain?
 

blackbird: sort of high traffic on wlan for idle.. And what's the cifs stuff, mounting smb shares?.. Is wifi powersaving on max? Skype, haze and the rest being as obnoxious as usual..

The i2c irq count looks very high, but all these figures might be a bit polluted since it kinda looks like your device wasn't idle the entire powertop sampling period

Re: how fast your battery drain?
 

i charge my phone at night to 97% (the highest it will go) when i wake up in the morning its down to 80% after doing nothing on it, so frustrating!

Re: how fast your battery drain?
 

You're not unplugging it, are you?

Re: how fast your battery drain?
 

i tested mine it only lasted 11hrs i left it running wifi(sip,skype) playing media player on bt...

Re: how fast your battery drain?
 

I don't think "only" applies there :)

Re: how fast your battery drain?
 

:D true,i cant replace this phone because of the battery life and music, the only problem now is where to find a bluetooth headset that last for atleast 8hrs as of now im using se vh-300 (8hrs) but its not the kind of headset for music :(, my last phone which is n82 only last 6hrs playing music and slick on wifi.

Re: how fast your battery drain?
 

Well, I usually have it connected to power supply. But sometimes about 5 hours while I'm listening to music, shell scripting, etc. at the same time with CPU at 1150 MHz...
Recently I've installed QCPUFreq, now it's much better. I change frequency when needed, and the battery drains slower.

Re: how fast your battery drain?
 

Did you mean to post this in the N900 forum, or are you looking for responses from owners of all Maemo devices?

Re: how fast your battery drain?
 

Mine keeps more than 3 days (72 hours) with quite low usage- always 2g, hourly mail sync (6am - 11pm) via wifi or data connection, few sms messages, about 10 min voice calls/day, 15 min browsing/day.
Have to add that it has been highly optimized by me to gain that performance. I mean few hacks&tricks and my own profile for Titan's kernel.
I suppose that going with high usage will give about 1 day of standby.

its been 24 hours since i charged this phone..
850mhz Lv ,mohammads hildon package , this swappiness package

Re: how fast your battery drain?
 

for those who have night-battery-draining problems.
in the repos is a app called alarmed.
this app allows you to configure your phone that it for example goes auto flight mode in at 00:00 and auto flight mode out at 06:00
you can configure the time how you need.
my battery drains 3 percent at night with this app

Re: how fast your battery drain?
 

Most battery related problems are a program that won't go idle. Or maintaining a 3G data connection with chat enabled, or wifi (not so bad) with chat.

Try this:
top -d 240

and leave it alone for at least 4 minutes.
Then look at the CPU % column and you can see what is using CPU time. Ideally everything should be 0%. Less than 1% might be ok.

or install one of the battery graph programs. I've used "BatteryGraph" to monitor what uses up the battery.

Re: how fast your battery drain?
 

I was having a random battery drain problem for a long time. It was "catorize" app that was causing it (actually it's the hildon-desktop interacting with catorize). Removed "catorize" and my battery lasts DAYS now.

Re: how fast your battery drain?
 

how did you discover this?

Re: how fast your battery drain?
 

I am overclocked to 250-900. My phone would not last 12 hours the way I use it. I can't tell you exactly, but I am at school all day, texting, IMing, emailing, browsing webz, taking pictures here and there, and def listening to music/internet radio... Basically, raping my battery :D :D :D

Maybe next two weeks I will leave my home in the morning with my phone charged all the way, and make logs of my battery graph and how long my battery lasts...

Re: how fast your battery drain?
 

Hey guys. I got my N900 last week and I charge it after I come home from work. It gets up to 93% charge I do some Wifi downloading and then I switch it off. I have or had one desktop all others cancelled and now I only have a calender, the weather app, 2 bookmarks and a couple shortcuts on the desktop. I have brightness app installed and the app that allows u to take screencasts and screen shots and see CPU and memory usage running in the background. most of the time i have no wifi connection at work. 2.5G is what i use but it's just there with my GSM mode cuz I got the app to switch between DUAL GSM AND 3G. I turn my phone on at 9am and it lasts me at times till 7pm where it's either 5% or less. So it basically lasts around 10hrs but I don't like that 10hrs bcuz it seems I always have to be trying to force it to make those 10hrs by switching it off or not using it at all or going into offline. i wud really just like to use my device comfortably with out worrying if it'll die on me thanks. btw i don't know anything bout xterm and stuff so if u offer that as help u have to speak noob. thanks again

Re: how fast your battery drain?
 

mine dies in about 4-5 hours cos of the transmission running all the time... :D

Re: how fast your battery drain?
 

Switching the phone ON/Off drains a lot of battery.. set it to offline mode instead if you dont want to use it.
Also if you have email client setup... setting to 2.5/2G will drain the battery more as phone will be using data for longer period of time( slow transfer rate). So juss use 3G if that's the case and see if it improves..

Re: how fast your battery drain?
 

I can't use 3G it isn't available where I live. Well at least I don't pay for it so I can't get it and yea I have the email client enabled but I doubt it refreshes using 2.5G bcuz it's way too slow and to my knowledge it only refreshes when I connect to wifi then it says refreshing. I only connect to wifi or GPRS when I want something other wise it just says 2.5 under the signal bar area and that's it. If I switch it to 3G with the app there's no 3G written just a blank spot under the signal bars or no signal bars at all.
