I still pick pick wifi over longer battery life. There's a reason you have
chargers for and they include two of them.

Re: Fix battery time from under 7 hours to over 9 days!
 

Are you sure that it is crashing and not freezing up for a bit? I leave wifi on all the time, usually so I can
ssh in to the n900. From time to time my session locks up for a while, even while I am typing. After a few seconds or minutes, it frees up again as though nothing had happened and all the characters that I typed while it was frozen show up.

Changing powersaving from maximum to medium helped a bit, but did not eliminate the problem.

Re: Fix battery time from under 7 hours to over 9 days!
 

Is there a way to create a control environment for people to compare battery charge life?

like no sim inserted and no widgits with wifi switched off and gsm/3g etc all turned off?

if there is a controlled environment set up then people can determine if they have a hardware fault or a software fault.

it will also allow them to enable 1 thing at a time for testing purposes and see what it is thats killing their batteries in 7 hours.

i would suggest a script that disables everything.

Trying to figure out whats wrong with everyones phones is to hard when there's too many variables so limit the amount of variables and keep the phones the same. use a good battery life phone and a bad battery life phone and enable 1 thing at a time and see what happens.

i don't have the n900 yet because ireland hasn't got any nokia love yet so i can't test this. but i do know from experience in work that a control environment is what you need for diagnosis of issues.

Re: Fix battery time from under 7 hours to over 9 days!
 

a question about USB via computer charging and usb power outlet charging, are they the same? sometimes i find the power charging outlet to be more faster

on the side note, my device was fully charged 10 hrs ago, i turned off the device and left it, now its been 8 mins and i have put it on charge via computer and the battry is not full

edit: it took about 30 mins for the light to become green again :s...

Re: Fix battery time from under 7 hours to over 9 days!
 

The USB charger that came with the phone is 5 V and 1.2 A. Typical computer USB ports can only provide 0.5 A. As such, charging will be much faster on the USB charger.

Re: Fix battery time from under 7 hours to over 9 days!
 

I notice my phone drain battery pretty fast too....like in the morning...my phone is fully charged. Of course, when i turn it on it will connect to wi-fi automatically in my house. So then i head to work and use Tmobile 3G. I didn't do much other than txting messages all day and maybe surf a couple mins of websites. That's it...my phone is basically idled the whole day from 6am to 2:30pm..that's 8 hrs and YET THE BATTERY DRAIN TO ZERO!!!!!

I think you're right about wi-fi drainage of battery..because i didn't use the phone much at all and yet it drained in less than 8hrs.

Re: Fix battery time from under 7 hours to over 9 days!
 

yep same for me. testing now.

disabled my wifi in terminal(sudo gainroot, ifconfig wlan0 down) and connected to the 3g network all day. been surfing the net for a total of 1 hour. downloaded an app. sent about 20 sms's (gf dramas).

disabled omweather using the internet. only manually update (this could be one of the issues here, you guys should have a look to how this thing is set up. i turned off GSM, WLAN in the settings and update to never. and made sure i only selected my state and no gps locations.)

my battery is at 70% after 6 hours. not bad at all. best day so far.
first time i was able to stay connected to the 3g without fast draining.

hopefully a fix through a firmware update comes before christmas

Re: Fix battery time from under 7 hours to over 9 days!
 

Does wifi access point have an effect here as well? Old wifi routers do not have all power saving possibilities supported. I am using Apple airport extreme. n900 connects to home wifi automatically and stays connected about 14h per day (Skype and Gtalk and 3 mail accounts) othervise with 2G connected in office 8h and about one hour in car bluetooth. Few calls and sms per day, with 2G I get about 30h usage and dual 2G/3G mode about 6h less.

Maybe I test without wifi but I seems not to cause too much drain on my environment.

Today I was at the meeting and suddenly the phone rang (I forgot the turn it off/silent).I tapped the reject button very fast because the phone was so loud and didn't know if the volume buttons mutes (well still don't know how to make the phone silent when you receive phone). Anyway the time I tapped the button, the media widget started to play online radio :( Can't remember how fast I turn the phone off completely. :)

Re: Fix battery time from under 7 hours to over 9 days!
 

I have the same problem. Took the phone this morning from wall charger (the light was green on phone). Turned it on and it showed 93% charge level. So if it can not charge it fully then I will last less time also.

Re: Fix battery time from under 7 hours to over 9 days!
 

Next time just put the phone on the desk face (screen) down. That will automatically silent the incomming call. Works quite well in my experience. :D

Hi I have the same problem. Today i charge full my mobile phone at 7:00 and the battery at 14:00 was totally empty. So I put the phone to the wall charger and battery was charged at 18:00. Now i have 18% of my battery.

I hear some people have had some problems with calendar widget eating lot of CPU and thus battery. Try going to X terminal and use "top" to see if there are any programs that use a lot of CPU while the phone is supposed to be idle.

Re: Fix battery time from under 7 hours to over 9 days!
 

in case a device has the wifi bug and you set it to offline mode (airplane mode), is wifi still transmitting?

Re: Fix battery time from under 7 hours to over 9 days!
 

Now that's an important question :)

You are supposed to turn off the device during take-off anyway though, and when you re-open it the bug won't be there:)

Re: Fix battery time from under 7 hours to over 9 days!
 

I can confirm this behaviour on my N900. I used wifi this morning in a shop and then disconnected. When I checked my phone just now it was hot and the battery is about 25%. I charged it this morning which is disappointing. I think the issue here is the power consumption when in standby mode. Someone just needs to make a script that will disable everything but texts and calls before we put it into standby mode.

Re: Fix battery time from under 7 hours to over 9 days!
 

I'm on just 1 bar down since I powered it up for the first time about 21 hours ago. I've only had wi-fi on for about 3-4 hours of that time. No SIM card installed, so nothing consumed there. Turned off vibration for most stuff. Turned off GPS. For me the battery consumption seems on par with what I would expect, so I'm hopeful it'll all be OK when bugs have been sorted out.

Re: Fix battery time from under 7 hours to over 9 days!

Re: Fix battery time from under 7 hours to over 9 days!
 

when i go into "top" it shows pulse audio for 5 seconds with 32% usage i thought this thing should not use that much cpu, not using anything, can media player shortcut on the desktop cause this problem?

Re: Fix battery time from under 7 hours to over 9 days!
 

@amorek13: From some other threads it appears that there's a pulse audio equalizer which runs in the CPU (unlike the actual player application), it's there to protect the speakers from damage from certain frequencies. If you try with a headset instead then the equalizer presumably shouldn't run.

Re: Fix battery time from under 7 hours to over 9 days!
 

Hard to say. And as offline mode doesn't recover the device from the Wi-Fi bug, it is possible.

Re: Fix battery time from under 7 hours to over 9 days!
 

marbles DRAINS the battery as well. so do other games. it is almost sick.

Re: Fix battery time from under 7 hours to over 9 days!
 

Of course usage that is both CPU and GPU intensive, will use the battery very fast. You don't get too long battery life with a laptop playing 3D games either.

my battery life seems to have gotten worse.

Only 11hrs today.

I only have nokia messaging on and the only widgets are the callender and data usage meter. I did not browse either.

I did dl something from extras over Wifi though. I then did the ifconfig command but after inputing it I dont seem to get a response. If i just do ifconfig wlan0 this is i see:

0 Link encap:Ethernet HWaddr 34:7E:39:42:B5:03

Does that mean the wifi was still on? Even so why would it drain so fast.
