Am having a real problem with my new Nokia 820 battery, please can someone help.
On Friday night battery was 100% by the morning it was 48%. Have obviously checked out the web for this problem. Have switched off all updating (weather and news) have disabled nokia drive and everything else on on that list.
last evening I again charged it to 100%, this morning it was 52%, this morning I have been using the phone to download apps BUT all over wifi phone is now registering battery 15%.
This to me seems unacceptable as I will have to permanently have it on charge if I want to use it as a phone!
Any suggestions would be gratefully received.
Can't you use "Airplane mode" overnight or do circumstances not allow this?

Thank you for your reply, yes I have complied with those suggestions and I will wait a few days.
So far (apart from the battery) it seems a really good phone but its a shame that after paying for all the bells and whistles I have to turn them off or disable them. LOL
Lets hope that nokia can find out what the problem is swiftly and get it sorted.
Hi, i have had my 820 a week now with very little improvement, i can use my phone and rapidly drop 15-20% in a 10 minute stretch, nothing intensive, just web browsing. I also tried,tap to send and it wouldn't even try it, switched the phone off and on and then went through to the screen but it still would not work.
Its a little annoying my brothers 8x is not experiencing these problems so far.
Thank you Farby,
seems like switching on the wifi is a major part of the problem.
Last night 100% battery - this morning (7am) 100% battery, although 5 minutes after checking that it went down to 95%. (wifi switched off)
Now (3.15pm) its at 85%,only used the phone to check battery status. no calls etc. so far it appears that just looking at the screen takes 5% off battery life!
Although this is an improvement, its certainly not going to last the 330 hours standby mode as advertised.
Advertised standby times are based on theoratically ideal conditions which are not possible to replicate in real life. It means perfect signal type and signal and everything switched off with the phone left completely idle. The closest you will get to this time is if you disable everything and leave the phone under a telephone mast and not touch it at all for a few days.
Those theoratical figures are used as a theoratical comparison between different handsets. It is impossible to give battery life estimates otherwise because it will be different for eveyone. Everyone uses their phone differently and use a different network and live a different distance from their nearest mast. So to compare, they use theoratical figures.

I face similar problems. I've got the Lumia 820 for a week now and the longest possible period was 7:30 h of usage now. Afterwards: battery flat, having to reload.
- wlan off
- bluetooth off
- nfc off
- only two apps with background activities enabled: wpcentral, microsoft weather (even Nokia drive is disabled)
- from 1 to 5 pushmail accounts (google and hotmail), it doesn't matter whether 1 or 5 are enabled as push
- facebook account linked to phone
- gps enabled
- live-tiles: see screenshots
- 4 to 6 calls à 5 min (20 to 30 min all in all)
- 10 times looking for mails or other notifications (not more than 2 min) --> 20 min
- 10 min browsing
--> 1 h activity!
- mostly 3g+ (@home) or h (@work)... whatever that means
Nokia Care told me, I should expect at least 2 days of usage regarding my phone activities plus the only advice: I should reset the phone.
Anyone facing such battery drain with "untouched" e.g. factory settings-like lumia 820s?
PS: My work lumia 800 lasts up to 3 days with the same settings!
I just got my Lumia 820. I charged my phone to 100% (and unpluggled it from the power outlet) before turning in for the night. When I woke up the next morning, the battery level is still at 100% (I think it's more like close to 100%
After combing through all the nightmare posts here, I disabled everything (except for my GSM phone radio so that I can receive calls/SMS . This test (unscientifically) proved that the OS and firmware seem to be OK. The battery could be another story as some folks could have gotten "rotten" batteries.
Next, I'm gonna turn on location and leave the phone overnight tonite and will post my result.
So far, I'm loving my Lumia 820 except:
- no windows explorer? (windows mobile had it) I wanna move and copy files in the phone!
- battery status percentage not displayed in the main screen of the status bar?
- no close button (pressing the back buton all the time is a pain). Anyone knows if there are 3rd party close buttons (yeah something like I did with my windows mobile phone a while back ago)?
c ya all
Thanks for the info.
I have just voted at the uservoice site for a file manager; apparently it's the No.1 requested feature!
Now on to my report:
- turning on location doesn't seem to sap the battery power (I guess that's bcos I didn't enable WIFI nor mobile data)
- battery still reports 100% in the morning (could this be a bug?)
I've tried enabling WIFI and the power usage seems OK:
- day 1 : 3.5 hours - about 65+ % battery drain
- day 2 : 2.5 hours - about 50+ % battery drain
The moral of the story is always turn off WIFI and mobile data when you're not using your phone.
The back of the phone is lukewarm only (I was worried about the "sizzling temperatures" complained by some users). So far no freezes or resets despite my constant mucking around with my new toy (yeah, installed tons of apps).
I hope Microsoft adds a file manager for the upcoming Windows Phone 8 update (codenamed Apollo+)
