Hi,
I'm going to buy this phone, but i heard that battery life isnt good. Can someone tell me sth about it? Is there possibility to use this phone for whole day (6am - 10pm at least) with average usage?

Yes, you can easily make it that long as long as you're not running it extremely hard. I'd say I use mine average, some may consider it light though. Mine has been unplugged for 17 hours and still has 35% battery left. I have 2 emails syncing (push, not interval), an average of 100 texts a day, light web usage (15-30 minutes), and the occasional game. I also am connected to WiFi most of the time, have GPS always on, and have my screen brightness set to low, but it's still plenty bright in most situations. I play the occasional game but it isn't as often, plus I have background apps such as weather syncing with a live tile. This is also on a phone that hasn't been broken in as well. It's only 2 days old, so it'll get even better over the next two days.

Yeah, it's pretty normal for a smartphone. You can easily get through a day with moderate use, but never expect to get through 2 days. I chose the 820 cause the HTC 8x has the same size screen but is almost as large as the HTC One X and it doesn't have a removable battery or an SD card slot; and the 920 is just to big for me. I have a One X and its a great phone but it's bigger than I care for, and Windows Phone just works.

After a weeks use and several discharges my battery is starting to improve, I can now get through an entire day 6:30am-11:00pm with average use but no more as it really does need to go on charge before it shuts down, I find this adequate enough but still hope an update can improve things slightly in the future.
When I say average use I mean a few txts & short phone calls and a bit of browsing, 2x email accounts sincing every hour, weather app & wpcentral running in background plus manually checking feeds on people hub for twitter & facebook etc on a regular basis ,Location and 3G on constantly(Good signal), Tap&send off & Dark Theme as uses less power.

Hopefully what happened to me yesterday won't happen again. I had decent battery like throughout the morning with 9 hours since last charged at 54%, that's 18 hours total and I'm fine with that. I only sent a few texts over the next 2 hours with nothing running in the background except for a weather live tile that has been there since day one and when I looked at my phone the battery saver had kicked in at 20% after only 11 hours since last charge. Luckily I was around a charger, but this should not have happened.

I read http://www.wpcentral.com/skype-and-constant-syncing-problem-windows-phone-8 and since uninstalling Skype have noticed a slight improvement, Whether this is just coincidence I do not know, The Battery still sucks though ;)
I wonder if that can happen even when I haven't signed into Skype? Because I haven't but that sounds like my exact issue. And it hasn't happened since either, just like they had said they haven't had issues.

Personally, I'm getting spectacular battery life with this phone. After about 2 weeks' ownership, I have not had less than 2 full days of use, and right now, incredibly I must add, it has been off the charger 2 days 3 hours and is still at 66% according to the battery control panel.

I have done little more than disable a couple of background tasks, and run the phone from 100% to zero a single time. I haven't installed much (not Skype), and while I'm not a heavy user, I'm not always moderate either.

I'm on AT&T and typically in LTE zones, with wifi for work and home locations. It has an EAS account with "as items arrive", and an IMAP account which checks hourly. Bluetooth, NFC, location services all enabled as usual.

Had the Lumia900 before this, and received a similar 2-day runtime, but not like this. Chalk me up to "pleasantly surprised" verging on "far exceeds expectations".

I can get 2 days of light to medium usage out of a charge. It's not quite as good as my iphone 4s but it's within about 10% of it and it's better than my atrix 2.

I had one day where my battery dropped like a rock... in hindsight I think it was because I had signed up for some podcasts so the phone was downloading 4 huge podcasts in the background one after the other. So don't be surprised if you run into a similar situation during the first weeks usage of the phone where it's downloading content in the background (maps, podcasts, music, etc.).

As for form factor... I went into the store to check out the 920 and 8X... I didn't even have the 820 on my radar. After checking out the 8X and 920 I picked up the 820 and it felt like the best form factor to me... immediately. Keep in mind that I prefer the wider 16:10 aspect ratio screen on the 820 vs. the 8X (I also prefer the power button on the side) and I found the 820 more comfortable to hold than the 920. I'm also a sucker for the inky blacks of AMOLED. I'd highly recommend going to a store and checking them out to which one is the best fit.

It's definitely a better size (smaller, rounded) and weight (lighter) for me. Also it's not slippery like the 920 color models can be. It's quite plain, by comparison. Screen is great, more readable than my 900 was.

It's solidly a 2-day phone in my usage. Frankly, the wireless charging back seems unnecessary, now that I see how rarely I'd need it.

Great to hear so many of you are getting good battery life, This is my second handset as the first developed a fault and was sent back, Battery was bad enough on that one, Maybe the rubbish battery life I am experiencing has something to do with the stock O2 ROM&Radio ? And possibly the poor reception in my area, Am hoping an update will fix this :(

My wife's 820 was getting good battery life for the first 3 weeks, but in the last week or so the life started falling off a cliff. Its now only lasting about 1/2 day before kicking into battery saver mode with typical use.

Settings:
-Wifi is off
-NFC/tap&send is off
-High-sensitiviety touch option is off
-BT is on and only used occaisonally.
-email was set to check "as items arrive" but we changed that to 15 minutes to see if it woudl help (it didn't)
-no trouble getting 3 or 4 bars in LTE mode
-double-checked that apps that have background tasks that can be disabled are disabled incuding Nokia drive (made no difference)

Gonna try messing around with it for another day or so and then I guess we'll do a warranty claim for a faulty battery through AT&T.

Same exact thing has been happening to me. I just removed a lot of apps to see of any of their background tasks was causing it, they weren't. The battery lasts a real long time when I'm not using it for the first part of the day, but then it just dives. I checked it after 9 hours and still had 84% left (only sent a few texts for the morning); checked it 3 hours later after only sending a couple emails and it was down to 60%. It seems like it lasts a long time while not doing anything at all, bit the moment you touch it, it just stays awake and burns it down. Very very frustrating and is about to run me back to my One X.

Just called AT&T USA and they do not have Nokia 820 batteries in stock at the warehouse for warranty replacement. They said I need to buy a battery at the retail store and they will reimburse my account for the full amount. Full phones and phones without battery&back cover are the only items in stock for warranty replacement at the warehouse.

If I am unable to find a new battery at local stores, they said to call back and they would just send an entire new phone+battery.

Setting up a whole new phone is a PITA when you're just talking about a new battery. As loosely as the battery fits, I'm hoping a company makes a larger one that fits but doesn't need a larger back. Seidio does this a lot.
