Having spoken to Nokia support they pointed out that using ##634# my battery is showing as 1442mAh, ie <1500... "A fix is due around the end of March for this" and there is no option to swap the phone out.
The official battery spec is 1450mAh, not 1500mAh, so you are well within tolerances.
Plus I do not believe you would notice the extra 50mAh even if you had them.
I'm happy with the spec, however this is based on the Nokia Lumia support team giving me this information about the fix that will arrive in March
I certainly do not have enough background "live" apps running to give a 13hour battery drain, and the support line confirmed this.
It's not the 50mAh that I'm missing, it's the fact that the support line specified the fact that the code is broken and will be fixed in a couple of months, in which time I will stop using my phone as it's no good for day trips away, or indeed holidays where I'd want to take pictures, use maps, etc....
The official link above gives the fantastic spec:
Maximum GSM standby time
we can dream
Recent system updates have removed some information from the diagnostic tools, which is not meant to be used for anything but indicative purposes and actually for service personnel only.
In Windows Phone 8 the tool has been completely removed.
Press the 'Accept As Solution' icon if I have solved your problem, click on the Star Icon below if my advice has helped you!
when i run disgnostic test on my battery, there is no result at all. Just screen with a white battery icon and no voltage and no current.
My phone has latest software, battery shows "?" all the time, drains really quick and needs frequent recharges many times a day. The phone is just 1.5 months old
I have purchaced lumia 800 2weaks back i tried to run the diagnostics tool under Battery Status> only voltage and current only displaying the "Full Charge Capacity and Remaining Charge Capacity" is not displaying.
OS Version: 7.10.87773.98
Firmware revision Number: 1750.0805.8773.12220

I contacted Nokia support and the advised me to take to Nokia Care to reinstall the firmware after reinstalling the firmware the problem is not solved.
Can anyone can help?

Dear Mr.. Micheal,
My name is Bhupender Singh, I am living in New Delhi (India). I am using Nokia's handsets since 2002 and having a very good experience from it. 1 week ago I have bought Lumia 800 Nokia Priority centre near by my home. Now I am having an issue of very low battery backup in my mobile. Due to this my mobile is being getting switch off very frequently. Now it's affecting my personal & professional working life. I am a big supporter of nokia's products but now these troubles are getting my mind change from your product.
When I bought this mobile the customer executives told me to charge this mobile handset for next 4-5 hours after that battery will be work properly, also the software of this mobile has been updated from Nokia care centre but the problem is still same. After seeing your comments in this discussions, I used that code suggested by you in my mobile, it is showing the mAh value while discharging 254 mA with 4.103V at 100% charged & when charging 46 mA with 4.314V at 100% charged
Please suggest me the appropriate action to do now,
Hoping you'll not let down my faith from your product.
Thanks & Rgds
IMEI was removed as it is unwise to publish unique serial numbers on a public web forum.
i have done as you said and my phone does not display a full charge capacity. also compared to my old nokia the signal srength is rubbish, can be no service on the lumia with full strength on my old phone, is this a ''characteristic of the phone'' or is there something wrong, it is really statrting to annoy me as i am missing lots of calls
