N900 battery duration

Hi all,

after some days using the N900 (with already lot of charge/discharge
cicles) I'd like to compare my battery duration with other people.

At least for me, battery doesn't last so much... for example one day I
charged it at 10:30 and it lasted only until 18:30 without using GPS,
fotocamera, wifi, bluetooth, ecc.... just 20 minutes connected in
UMTS/HSDPA and the rest of the time keeping it in my pocket.

I don't have any particular application installed... I only use one
virtual desktop and the widget are: calendar, facebook, forecast.
Nothing more.

Another day the battery only lasted 6 hours... browsing a little more
(30 minutes in total).

Anyone else is experiencing the same problem?

p.s: today I'm not going to use it to connect to internet, just using
it as media player (I'm in the university library) listening it with
my headset. I'm playing mp3 songs since 1 hour and the battery is
still displayed as full. Not bad.

That sounds a bit low.

Not that I've seen longer life on mine, but I use mine a lot. A day or
two ago it survived from 8 AM to 2 PM while online using 3G (and later
WiFi), with almost constant web browsing, email checking, note taking
and GPS usage. I started charging it before I saw the 'low battery'
warning.

Have you tried disabling facebook and forecast?

Have you tried running powertop in an xterm and looking at the output?

I wish I had the same duration :(

I can try, but... today, having them enabled, I'm listening to mp3
songs, only using media player and the battery is still full charge.

command not found... do I have to install it?

My experience is that it lasts fine from plugging out the charger until
I get home in the evening around 20h or 21h. If I don't plug it in, I
tend to be out of battery around midday the following day.

That said, there have been days when it hasn't lasted a day, especially
with wifi on a lot, and when I've made several phone calls.

I had a problem with syncing my contact list (which I'll be reporting as
soon as I get time) which caused me issues during the week, so for the
time being I've moved back to my old phone for cellphone calls, but I
move to the N900 as often as I can in the office.

I installed quite a few apps from extras and etras-testing, but nothing
which is on all the time, except "sync for exchange" - and to reduce
battery usage there I've reduced sync frequency to once every 4 hours there.

Web browsing seems to be the major issue, especially on JS or Flash
heavy sites.

Cheers,
Dave.

I get a little over a day, so if I forget to charge it at night, it's game
over somewhere early next day (have a spare battery or a microUSB source on
the ready if you're as forgetful as I am). Intensive web and OpenGL sucks it
dry real quick, but haven't yet measured it for exact numbers. I also suspect
having 5 IM accounts with ~700 contacts doesn't help either. Have not tried a
video marathon (yet). Wifi always on, GPS off, and I don't use GSM/3G data at
all (actually disabled 3G in the data options in hope of better battery
times). Completely different battery use-case than the N8x0, much more like a
phone (whereas my N810 used to last me 3-4 days).

PS. Somebody also made it possible to charge when battery completely dry (not
always possible on previous tablets :( ), thanks for that :)

Re: N900 battery duration [In reply to]

Hi Andrea,

I've been using the N900 since last Saturday as my main mobile phone and
messaging device and for some light browsing and blog reading. I use the
"always on" Internet connection option and while I'm in the office the
N900 frequently switches between Wifi and Edge (no 3G here in the middle
of nowhere). I also installed quite a few apps and I use all the virtual
desktops. So far the battery has usually lasted between a full day and
one and a half days. Compared to what I've seen some of my friends
getting out of their iPhone batteries and what I've read in the Palm Pre
reviews - since the 3GS and the Pre use the same CPU - I think getting
about thirty hours out of the battery is not too bad. Much less with
moderate usage looks like a problem with the battery to me.

Cheers,
Kai

I have the calendar and Facebook widgets on the desktop. And since the
last reboot (yeah, there are still some stability issues ;-)) two days
ago the Email, Messaging, RSS, Phone, and Internet apps are open.

Re: N900 battery duration [In reply to]

Hmm, Skype and apps like that might suck quite a bit of battery,
depending on how chatty they might become in their idle states. Knowing
a bit about Skype from monitoring a large company network, especially
when it does not get a connection or an unreliable connection it tries
to connect to the next Supernode very often, at least once a minute.
Wireshark might help you to find out how "chatty" your N900 is...
If I have some time over the weekend, I could run some tests with
Wireshark and Skype/Foreca/Facebook and whatever else is usually running
on my N900 to see how often these apps actually send traffic in their
idle states.

Cheers,
Kai

it would be great!

Anyway, here is the result of powertop execution on my N900:

I hope it can help you to understand what's happening :)

Re: N900 battery duration [In reply to]

Hi

p.s: my N900 was connected to charger during this test... do I have to
disconnect it before doing the test?

The charger seems to mess up the numbers at least somewhat. I'll do more
testing with powertop later.

Well, I did a quite test right away.

This is Media Player playing 192kbps VBR Ogg/Vorbis without charger:

C# | Ratio | Avg/dura | Frequency | Ratio
--------+--------+----------+-----------+--------+
C0 | 66.3% | | 600 MHz | 16.5% |
C1 | 0.0% | 3.1ms | 550 MHz | 0.0% |
C2 | 7.4% | 3.3ms | 500 MHz | 50.6% |
C3 | 26.3% | 7.6ms | 250 MHz | 32.9% |
C4 | 0.0% | |

And the same with charger:

C# | Ratio | Avg/dura | Frequency | Ratio
--------+--------+----------+-----------+--------+
C0 | 65.6% | | 600 MHz | 15.8% |
C1 | 0.0% | 0.1ms | 550 MHz | 1.3% |
C2 | 8.8% | 2.7ms | 500 MHz | 52.7% |
C3 | 25.7% | 7.5ms | 250 MHz | 30.2% |
C4 | 0.0% | |

No change there. Not sure what I did with an ealier firmware as there I
did saw a clear distinction. Maybe I just messed something else up..

Re: N900 battery duration [In reply to]

When I think back to the N900 hardware lighting talk and the warning
about not fixing the CPU's clock to one of the high frequencies, I guess
that connecting the N900 to a charger should not change the power
settings of the system, i.e. not like with a laptop CPU that's behaving
differently when running on batteries. But that's just a guess, someone
with more knowledge of the ARM Cortex 8 architecture or even better the
N900's architecture (Nokian's, where are you?) should have the right
answer to that.

OK, I'll do some sniffing over the weekend with a Wifi connection and
post the results on Monday.

Copy paste from the link above:

C# | Ratio | Avg/dura | Frequency | Ratio
--------+--------+----------+-----------+--------+
C0 | 27.3% | | 600 MHz | 19.1% |
C1 | 0.0% | 0.2ms | 550 MHz | 0.0% |
C2 | 8.8% | 3.0ms | 500 MHz | 21.8% |
C3 | 63.7% | 34.2ms | 250 MHz | 59.1% |
C4 | 0.1% | 6.0ms |


Was that an idle device? It really doesn't look like that. Here's a same
set from my idle device:

C# | Ratio | Avg/dura | Frequency | Ratio
--------+--------+----------+-----------+--------+
C0 | 0.7% | | 600 MHz | 0.0% |
C1 | 0.0% | | 550 MHz | 0.0% |
C2 | 0.2% | 1.2ms | 500 MHz | 0.0% |
C3 | 99.2% | 211.0ms | 250 MHz | 100.0% |
C4 | 0.0% | |

C-state is the sleep state of the CPU (afaik) and the frequency is the
Mhz the cpufreq chooses the run the device based on the cpu load. I
don't know what it takes to get to C4.

no, it wasn't idle: I was connected to SSH and executed command from
my PC, wifi was ON, connected to Skype, GTalk, SIP account.
Facebook, Forecast widgets ON.

That still counts as an idle device :)

Or at least should. But obviously something is running actively there
all the time.

Have you tried running "top" if that shows something?

This is now run on a 41-10 release without SIM, without WLAN, without
charger, with only ogg-support and sshd installed (default widgets on
the desktop), and display blanked via the lock button:

C# | Ratio | Avg/dura | Frequency | Ratio
--------+--------+----------+-----------+--------+
C0 | 0.3% | | 600 MHz | 0.0% |
C1 | 0.0% | | 550 MHz | 0.0% |
C2 | 0.1% | 1.1ms | 500 MHz | 0.0% |
C3 | 0.2% | 15.2ms | 250 MHz | 100.0% |
C4 | 99.5% | 2297.0ms |
