In my case I can certainly report that switching on 3G sucks the life from my battery and causes the handset to warm up noticeably. This does not happen with wifi on. You might need to restart for the non-3G config to work properly. Try it out and report back...
Is nokia solving this:
Try explaining what you want solving instead of linking t a picture with foreign writing on it?!
You must be one out of a thousand...
I'm fed up with the poor battery life and slow response from Nokia. I'm going to sell my Lumia and return to my good old Samsung...
I understand your frustation. But the battery is actually very very good on a Lumia 800 when you uninstall the diagnostics app (and reboot the phone).
Before, my battery would run down quite fast (10 to 12 hours max). Now I'm getting better battery results then my HTC Trophy. It lasts about 1,5 days with Wi-Fi on and 3 ActiveSync mailboxes on.
The diag app seems to run, even when it's not visible. I believe it's made from native code so it can do a lot more than regular WP apps. Which includes depleting the battery. I believe this app might be running all the time to collect diagnostic data.
After removing the app, my Lumia is amazing! (everyday, haha)
Well, it is the 3g. i have swtiched back to EDGE and the power consumption has dramatically improved.
Only 1% battery drain per hour, with some whatsapp and like reading 5 emails. Email syncro is set to every 30 mins. No wifi.

Does it? I will try it out. Since when did you uninstall the diagnostics app?
I mean, how much time have you been running without it?
EDIT: I did not read it well at the beggining. The problem is not wifi, it's 3G. Wifi has good drain values.
I activated the 3G network connectivity and it shows H which means an active data connection has been stablished, and it should, as the manual says, show 3G, which means that it is connected to a 3G network but no data transmision is being made.
Maybe the bug is all this about, the network connection keeps open like if it was downloading/uploading.

yeah, you're right! my omnia always shows 3G. when i download something it shows 3g+. The lumia shows always H. sometimes 3G. NOKIA fix that please! that can't be so hard to manage :/ but when my lumia show the 3G icon and i download something, then it does not switch to H. maybe it is simple a display error and has nothing to do with the problems...
Have had my Lumia for 7 weeks now and the battery life has been very unpredictable... First few weeks before the 18th of jan update the battery life was rubbish. After the update it was alot better, would get more than a day out of the phone but then sometimes less, seemed to change every other day. Now the battery life has gone back to about 10 hours with light enough use.
I leave 3G on all the time and generally have WIFI turned on during a 9 hour work day. I mean what's the point of a Smart phone if you have to turn these options off. Id like to know are recent Lumia owners having the same problems. I think all the Nokia advertising is starting to bug me now, trust me its not 'the amazing everyday' owning this phone :I
Also i have noticed if i switch the phone off and try restart it, i enter my lock screen pin number and the phone reboots. It happans at least three times until i get to the main metro screen.
It's hard to say just using semi-anecdotal comments in this forum - especially when Nokia are appearing to be so counter productive and not helping with any significant feedback on all the issues relating to battery problems, phone crashing events and OS 'quirks'.
But - I think it's clear, that in spite of the latest battery firmware 'fix', that there are still some BIG unresolved issues with power management / 3G radios and OS bugs. My own battery life fluctuates massively for reasons other than my input or use.
Maybe the only action that'll catch Nokia's attention is an even bigger return rate that this phone probably already has. I am warning as many potential Nokia WP7 customers to stay well away from these products, at least until they get their act together and resolve these ongoing problems.
Very unimpressed with both Nokia and Microsoft's level of customer interaction. At this rate, I don't intend on buying any of their future poducts.

Mio_BB, how did you get the firmware updated to 11501?
It seems, poeple who sent their Lumia 800 back to Nokia for repair, receive it back with the 11501 firmware update... and it seems to have solved the battery problem.
But, I can't find this update online... and the phone (and zune) claim that the firmware (11500) is up to date.

I have just received my replacement Lumia and it also has the 11501 firmware from Nokia pre-installed.
So far battery life is holding up (showing 1 day 11 hours after full charge), but it has only had 2 full charge cycles. I suspect the problem, if it returns at all, manifests itself after a number of charging cycles.
As an aside, I was at a customer the other day and one of the guys I was talking to was also waiting for his new replacement phone to arrive. Getting a second handset seems to be almost a rite of passage with the Lumia!
Well after another couple of weeks of use of my black L800, after the update..I've noticed that the battery status indicator is always going haywire even with a consistent moderate usage..Anywhere from 42hrs to 62 hrs..When I use the phone a little heavy the life starts draining like mad and some times its minimal drain..
My usage is:
60-70 odd messages..
Email sync every 5-6 hours manually..
A little bit of Office and Adobe Acrobat Reader used..
Phone alarm being used once a day..
Total calls worth 30 odd minutes..
EDGE left on..
Theme dark with Nokia Blue..
Everything else off..
Network selection set to manual..
Ear piece volume level kept at 10..
My opinion as like stated in some of the earlier posts is the driver bug which are forcing some or most of the drivers to stay open or behave irraticly and makes the CPU increase its consumption to run when in reality the system is idling and there by draining the battery..The driver issue could also explain the call ending bug that I also face occasssionally..FYI it could be also because the phone goes into network scanning when it doesnt have too..Thats the other thing even with a manual network selection the phone starts scanning again for the network even when the signal bars are full..
NOKIA YOU NEED TO REDO THE DRIVERS AND RELEASE A BRAND NEW FIRMWARE UPDATE FOR APPLYING THEM SOON!!
Until NOKIA rectifies this phone I will not recommend the use of any nokia product after this current experience..

I've handed mine in to a Nokia 'Care' centre for them to poke it with a stick for 10 days (and then hand it back, probably in the same state!).
Not impressed with the care shop - they just took the phone itself , no protective case or box, lobbed it on the side after writing some inaccurate notes on their system about the issues I was having, and said it'll be 10 days.
Classy service Nokia. Classy.
Edit: Just to add to this: We each spend £400 on a new Nokia product which then, for many users develops (several) big issues that impact its primary function - (Battery life & continuity and not being able to end calls) rendering it not fit for purpose.
So I then have to take my £400 investment to a care center and be without it for up to 10 days, all at my expense. And Nokia don't even have the common sense, politeness and good business sense to offer customers an apology and issue them with a temporary interim replacement handset? Your product is faulty - you should make a mends for the inconvenience caused.
(I'm not talkinmg like-for-like obviously. Just lend customers basic call & text handsets)

As Nokia obviously doesn't monitor its own site do you think it may be worth emailing them a link to this thread and ask them to read it?
I have a sneaking feeling that they know very well there is an issue and may add a fix to this under the cover of another 'update' without acknowledging or commenting that there was ever an issue. - OR is this wishful thinking ???
***Just emailed it to them with some comments - lets see what they say - I'll post their response when I get it***
