Thanks for the Link

Very interesting

Here a Link with also a simple solution for reboot/restart. Since about 12 hours it runs without draining the battery (in moment about 10mA)

[N9MFE]

My current status:

Nokia N9 64 GB PR1.1 20.2011.40_4_PR_001

I have not used the phone at all during these tests.

No email in use, no Fb in use, no absolutely nothing, all accounts disabled, never used developer mode.

1. all apps removed except the Nokia default apps, reboot -> full battery lasted 6h

2. re-installed PR 1.1 using Nokia Software Updater -> full battery lasted 5.5h

3. re-installed apps Battery Usage and Resource Monitor (RscsMonitor) from Nokia to see what eats up the battery:

Battery Usage: Avg Idle Consumption 233mA
RscsMonitor: Top Processes: /usr/bin/smartsearch CPU % 83-92 constantly.

The phone itself is not especially warm, quite normal room temperary,

maybe just slightly heated.

What next?

In my opinion there is nothing wrong with the battery itself since it loads full but
rather something wrong with the process that clearly drains the battery quickly.

Something else to be tried?

The steps above are the only ones i ever done for this phone,

i'm not really familiar with the difference of hard reset vs flash vs re-install PR 1.1.

As far as hard reset is concerned, there are just too many issues regarding hard reset, therefore i'm not really too willing to try it just yet:

"Nokia Ovi store on my N9 stopped working.

Everytime when I click download it says: Caution! Before you can continue the corrupted app must be deleted.
 It starts downloading, but every single time the setup or/and download fails."

"I've reset my N9 five times today and it just won't work! Even my e-mail stopped working"

"i tried this and now have black screen only, any idea?"

I really cannot use a phone that only stays up < 6h idle.

Any suggestions?

Did you really re-installed PR 1.1 by Nokia Software Updater ? - if yes, please be PATIENT as indexing (smartsearch) will take time up to 1 full day ... honestly, I suggest you enable developer mode - it might help for your both problems (draining battery and Nokia store problem) as well as you will need it for a boot too (reboot -u ... through terminal), if needed later, as it has been used to fix some cases - read here: http://talk.maemo.org/showpost.php?p=1121191&postcount=61

I will be patient and wait for the smartsearch to get everything finished, i will give it now couple of days.
Next step will be activating the developer mode,

then devel-su - followed by reboot -u

I will let you know what happens.
Cheers for the mental support and tips so far

By the way, did you check that all your apps are updated ones (through

Settings -> Applications -> Manage Applications -> Check updates) ... there was appr. 10 apps updates after PR 1.1 update (you have to update them again after re-installing PR 1.1 too) ... if all apps are updated too, it should say you there that "all is updated or something like that" ...

I had same problem. Drain battery with idle consumption around 100...200mA ...it happened first days, then it went down after few full cycles of battery charge. Then happened again after i changed my sim card for another line and company. So i made hard resets, 5 times, i had the same problem with the store... Same error message a conflictual app had to be deleted to install apps (as my nokia os was brand new with NO apps on it, strange) So i reinstalled pr1.1 with nokia software updater, the store worked and my nokia started to have normal idle consumption (from 7mA yesterday to 30/50 today, because i transfered again all my 30go stuff music and videos and its a big work for the smartphone, and added again all apps with wifi. Tonight the idle consumption is 25mA and getting lower and lower, should be ok soon. It seems that the N9 need time to accomodate and adjust itself everytime the os is new, everytime a new operator and sim card is added, or after long transfers and sync connections to a pc. So ill see tomorrow morning abd tomorrow if finaly everything is ok again. Its the main issue for me. i became a bit paranoid last days about the battery life, checking all the time idle consumption and sometimes hesitate or being scared to use too much my N9 as i dont wanna see this problem again. When idle consumption grows the N9 becomes really poor about battery life, and u feel that you dont want such a phone anymore, even with so cool features, but just a phone with a normal battery life. So that's a main issue to fix for me, i dont wanna deal with this every weeks or else, or maybe i'll change for another phone if there is no solution.

Does devel-su / rootme in the developer mode break the Nokia N9 product warranty?

The original problem concerning the power consumption still remains exactly the same as yesterday, same values remain for smartsearch / avg Idle.

I will still keep waiting smartsearch progress, just interested meanwhile about the rootme/warranty issue.

Smartsearch battery drain power consumption SOLUTION

Finally got everything working, this is what i did:

1.Settings/Reset/Restore Settings
-> original problem remained the same

2.re-install of PR 1.1 using Nokia Software Updater
-> original problem remained the same

3.reboot -u using Settings > Security > Developer mode (devel-su/rootme + cd /sbin + ./reboot -u)
-> original problem remained the same

Solution:

4.disable Developer Mode if it is enabled

5.Settings/Reset/Clear Device

6.enable Developer Mode, this is necessary to be able to reinstall Nokia apps

7.disable Developer Mode once all the Nokia apps are reinstalled

Result:

Resource Monitor / Top Processes: no smartsearch in the list anymore
Battery Usage:

Avg Idle Consumption now 38mA, might still go down more during time (original 233mA)
Battery lasted 6h before, now lasts 20h minimum, even with normal use

Conclusion:

In my experience Clear device will resolve most likely all N9 battery drain power consumption problems,
i should have done Clear device right in the beginning but was just too shy due to new device and platform.
I would assume same applies most likely also for Nokia Lumia WP phones ie.hard reset also most probably works there in similar problems.
Brand new devices with brand new software always is a challenge for the first users but challenges are there to be tackled.

I wish Nokia Care could have given me some real help, this time i had to learn it the hard way.

One very important part in the solution was the very active N9 Meego community, call that a real ecosystem with wide knowledge.
Long live N9, long live Meego, i am again as happy as can be owner of this piece of brilliant software and hardware and
wouldn't change it to any other. No wonder N9 has won such many awards.
I hope this solution helps as many Nokia users as possible.

In addition to my previous post, i suppose the following would probably be the

simplest way regarding the solution that was mentioned

1.Settings/Reset/Clear Device
2.Install PR 1.1 using Nokia Software Updater 

I never tried exactly that combination in that order so not sure, but pretty sure that would work.
