So in real life use case (i assume people who will buy it will actually use it as a phone) the use time will be longer. I guess I need to do more testing then :) Although I'm not sure how to accomplish that as I need my SIM for the daily use.. The previous test was without a SIM card. The device was very idle and run for 93.75 hours (with a guessed few hour error marginal). After charging the battery I inserted the SIM card, rebooted and started a new test. Why reboot? I would expect most people just to charge without shutting down the device. (You may remember that e.g. N8x0 use less battery if it's put to offline-mode instead of being shut down for the night.) I received two calls (hung up immediately), I received two SMS messages and sent one, and the notifier led was blinking for 45 mins at one point. Otherwise the device was idle and run for 93.62 hours. So pretty close to the test without a SIM card. I have a small shell script running there that writes a log every 60 seconds. After writing the log it runs the sync command and starts the loop again. I'm assuming it doesn't affect the total run time much in an otherwise idle device. - Eero ___ maemo-users mailing list maemo-users@maemo.org https://lists.maemo.org/mailman/listinfo/maemo-users

Well in the case of the N8x0 when booting up the screen brightness was up to its maximum. When booting up all the tablets chips and fishes uses maximum energy until the PM kicks in and takes control of everything. This consumes A LOT of energy. An N8x0 in offline mode (idle) consumes much less energy in a night than its minutes-long start up. -- anidel ___ maemo-users mailing list maemo-users@maemo.org https://lists.maemo.org/mailman/listinfo/maemo-users

After charging the battery I inserted the SIM card, rebooted and started a new test. Why reboot? So that I know the start scenario is the same. Not rebooting and doing several tests in a row easily leads to increased memory consumption, dying processes and weird behaviour. I would expect most people just to charge without shutting down the device. Of course. I'm not booting the device in normal usage. (You may remember that e.g. N8x0 use less battery if it's put to offline-mode instead of being shut down for the night.) How's that possible? Offline mode shuts down the wireless stuff but still runs the cpu. And, afaik, shutting down the device shuts down the cpu etc. as well (not sure what happens if you have alarms there).

new on list / sponsoring ISP in Germany
Hej all, I'm new to this list, subscribed because I'm very interested in maemo, especially on the upcoming N900. I'm using Debian Linux since early Potatoe and hope to have a good chance getting these things (desktop and mobile) good together. The N900 is announced for late November 09. Does anybody know, if there will be a sponsoring provider in Germany selling this little thing for small money including a fair (flat-) rate?

What is true is that if you turn your tablet off and on *many* times during a day, you will experience shorter battery duration than if you just put it to sleep. The reasons are as stated: when starting up and shutting down you are running the machine at full blast for a significant length of time, which rarely happens otherwise. However, if you only turn it on once or twice a day, your battery will last many more days if you shut it down than if you leave it on, even at maximum power savings.

Is that something that affects the MP3 in a different manner than Ogg? It should be the same, but since you are interested in the power consumption of the decoding activity - if i understood correctly - then you get an unknown term, which can also have 2nd order effects due to the different timing and choices that both cpuidle and cpufreq could make. iow, if you have time, it might be interesting to run the test again with an headset. I repeated three runs with ffvorbis and got a bit over three hours more battery life with the headset connected compared to my earlier ffvorbis tests without the headset. -- Tuomas ___ maemo-users mailing list maemo-users@maemo.org https://lists.maemo.org/mailman/listinfo/maemo-users
Re: new on list / sponsoring ISP in Germany
Hi, cool that you are joining us :). no at the moment, nothing is known about providers+n900 for germany, but you should keep an eye on t-mobile (also because they have the best coverage and prices for smartphones) On Tuesday 10 November 2009 16:41:23 Boris wrote: Hej all, I'm new to this list, subscribed because I'm very interested in maemo, especially on the upcoming N900.
