Thanks for all feedback.

Re: Battery Life N800 + OS2008
with regard to modest, it supports imap idle and seems to refresh instantly. i just set the poll time to 2 hours and yet see my new messages immediately. this seems to stop the new mail notices which i am guessing reduces the load as that seems to be triggered by the active polling. nice though as there is no need for an every 5 min check. short tap on the home key gives you a view into how many unreads you have in your selected mailbox.

Re: Battery Life N800 + OS2008
Piotr A quick thing to check is running 'top' and looking for cpu bandits. I had a 3rd part app gobbling up cpu due to a bug once; another time an internal launcher app was going nuts and it turned out to be caused by an sdcard corruption problem.

My n800 battery life seems fine with 8OS, although it's more of a subjective than objective measurement.

Re: Battery Life N800 + OS2008
Hi Piotr, If you have installed OpenNTPD, please try to remove it. The init version seems to not battery friendly, because it uses network per 3min. I just modified some parameters and testing. If it seems to be OK, I will release 2nd version.

This is the state of things: - during development we test all the common expected usecases with the stock fw - we make sure that the claims we make on the advertisement material and in the box are backed by corresponding reality - the last number i saw were pointing to above 20 days of standby idle (meaning that you charge the battery and let the device untouched for 20 days) even if we officially support about 10, iirc - the higher frequency does _not_ affect negatively the use time unless you are doing something cpu-intensive I would suggest you to do like others have done before: try without any extra application, then proceed by bisection, by installing half of those you have now and see if there is any significant decay of battery life. -- Cheers, Igor Igor Stoppa <[EMAIL PROTECTED]> (Nokia Multimedia - CP - OSSO / Helsinki, Finland) ___ maemo-users mailing list maemo-users@maemo.org https://lists.maemo.org/mailman/listinfo/maemo-users
Re: Battery Life N800 + OS2008
Hi, I have experienced exactly the same with os2008beta. I also began wondering if my battery began to wear off signiricantly. I have just installed the current os2008 and will see how it affects battery life.
