You don't setup a MOTO blur account on this phone. Hopefully you backed up everything through your Google acccount and can get everything from it.

Oh, that sucks...I liked how it restored all other accounts for me, now I need waste 30 minutes just to enter all the passwords...

Thanks for the response though.

[Nokia Lumia 800] prowede:
e.g. 1 hour web-browsing, 1 hour call, 30 SMS, 2 hours music per day

With 3G data connection on, WIFI off, etc.

And lasts for xxx hours / xx% left after xx hours

Can you share the battery performance of Lumia 800? ;)
[Nokia Lumia 800] jhughesy:
First day I got 16 hours, second day 22 hours and now its up to around 24-25 hours.

3 email accounts (check every hour), 1 hour web, facebook, couple of calls (around 10 mins) and a few sms. Wifi on.
[Nokia Lumia 800] RyanMacG:
92% after nearly 3 hours, push on for 3 email accounts, Mehdoh and twitter sync in the background. WiFi is on but not connected at some points so I've switched it off. I've also sent a few texts, downloaded an app or two and some attachments.

Current estimate for battery life is 13 hours left.
[Nokia Lumia 800] prowede:
data connection always off?
[Nokia Lumia 800] jhughesy:
I always keep it on. Bluetooth is off.
[Nokia Lumia 800] X3n0n:
2 mail account with push, Me tile with Facebook and twitter.

Wifi always on, event if no wifi station near me, Bluetooth on even if no device connected (it's for my car).

Game sessions (20-30mn), market place browsing, texting...

About 15h.
[Nokia Lumia 800] jhughesy:
Out of interest is this your first day battery? Because mine seems to be getting better every day.
[Nokia Lumia 800] X3n0n:
I have the phone for 1 week, I never get to 0%, this is just what the battery saver screen tells me.

But, I think this good estimation more or less 1 hour.

[Nokia Lumia 800] Venstar:
Question about charging

This marks my return to Windows (I had the venerable MDA Vario II) and more recently I have been using Android (Hero & ZTE Blade) but now it's all about Lumia 800 and I'm blown away so far with this phone & WP7.

I just wanted to ask if this is "normal": with the phone completely switched off (not sleeping) I then plug in the charger the phone would boot up.

If the phone is on & plugged into the charger and I switch it off it would then reboot. Is there no way to charge the phone without it being on?

Thanks.
[Nokia Lumia 800] Ikkari:
I have to wait 1 or 2 weeks before reviewing the battery life, every new phone i used in the last years improved dramatically it's battery life after about 10 charges.
[Nokia Lumia 800] stueyboy:
Got one of these last Wednesday when they came out. Moved on from HTC desire whcih I enjoyed a lot for different reasons. The Lumia is a superb phone but I was a bit worried about the battery life on the first few days.

After a usual day the battery was at 15% the first day then 20% the second. Granted I was fiddling with it as is normal for a new phone but my HTC would be on about 50-60% doing the same.

I remember that you need to do a couple of full charges and the battery should get better and today it was on 50% when I got home so that is a big improvement and hoping it will improve more.

I did have both my mail accounts on push to start with but have changed them to once every 30 minutes. Wifi always on, bluetoooth always off. All other sync options on so live tiles and people hubs syncing however much they do.

All in it's getting better and I am extremely happy with the phone. I took some pics yesterday and they look amazing on the PC but not so good on the phone so don't despair if they look crappy when you review them on phone.
[Nokia Lumia 800] brummiesteven:
You may have seen that I've been getting good battery, today I used the phone a LOT after going to visit a family member and spending a lot of time on the bus (traffic in Birmingham is bad at the best of times :P) here's the results:

Took off charge at 11:00. It's now 21:03.

Around 3 hours of music. Wifi always on, Bluetooth off. Spent about 1/2 hours not connected to celluar network. Lots of web browsing and using web applications like Facebook and Twitter. About 30 mins gaming.Facebook chat on. 20 SMSs sent, 1 phone call and a few IMs via Facebook and MSN Messenger. Twitter and facebook accounts both connected. 1 Email service, about 15 emails received today pushed to the phone as they arrive.

Remaining battery life: 28%

Estimated time remaining: 2 hours (will jump to 3 with battery saver on)

Time since last charge: 10 hours.
[Nokia Lumia 800] DarkVasyaK:
I think it's a very good result for those who got used to charge phone every night. Just OK :)
[Nokia Lumia 800] Ikkari:
Go to dialer and call ##634# this will activate the diagnostic app....

There is a option called Battery Status in the diagnostic app...

From there you can check your current discharging, maybe it's i better way to compare the discharging....

Check with different options what is draining your battery..
[Nokia Lumia 800] maverick1103:
Had mine a week and a half now, my average use is as follows:

Take off charge @9am, Wifi on all the time, have Facebook, Twitter synced through People Hub.

Have Gmail synced but on Manual, Outlook on push and Windows Live only for Xbox Live.

I also have FB app with push notifications on.

I prob listen to music at most half hour a day, very little browsing on phone due to using SGS2 as my main phone, check Marker place a couple of times, no SMS sent and luckily if I make a phone call on it.

This is my works phone so mainly used of emails. So I receive on average 30 emails a day.

Phone switches to battery saver about 5ish and then runs on until about 11pm before dying.

So my thoughts are standby time is crap for what I use it for, battery saver is good but that's due to auto sync being turned off!

[Nokia Lumia 800] Ikkari:
Just send it back or replace it... mine is actually doing pretty fine... and still getting better :)
[Nokia Lumia 800] PaulSlide:
That's great to know, thanks amigo! Some useful tools in there as well as the battery info.
[Nokia Lumia 800] nok_fusion:
I use the tool,it tell me that my battery capacity is 1520Mah (in nokia site it notes that the battery of lumia 800 is 1450mah) so my battery is really good,isn't? :)
[Nokia Lumia 800] brummiesteven:
Capacity: 1508mAh

Discharge rage: 141 mA
[Nokia Lumia 800] nok_fusion:
Mine

Capacity: 1520mAh

Discharge rate: ~280 mA

the discharge is pretty high no?

i have it for less than 1 week

the calibration take how many time? 2 weeks or more?
[Nokia Lumia 800] X3n0n:
Tiens, buldo ici :D

The discharge rate is updated on very short basis so, if you don't touch your phone, it will show about 150mA,

You can see when scean is on, and when it's deem.
[Nokia Lumia 800] nok_fusion:
haha funny :p

yes i test with no touch the phone and it stay ~150mA

but the battery drain really fast,left from home at 7.30 am battery 100%(show me 12hours remaining time) ,10.30 am 49% (3 hours remaining time) i just listen podcast during 30 mn + web for 20 mn
[Nokia Lumia 800] stueyboy:
Had the phone a week now and in general use I'm using battery at about 4% an hour. That's my usual use and compares pretty well with my previous HTC Desire when it had Sense UI installed. I'm using several live tiles checking mail at 30 minutes.
[Nokia Lumia 800] robinVerdegaal:
FIRST DAY

8.30

full charge

brightness auto (medium)

wifi on

bluetooth on

30 minutes of usage in transit (ebooks / internet / twitter / bt stereo music)

13.00

full drain 0% (I was like, 'wtf', and then I was like, 'damn baby')

SECOND DAY

brightness medium

wifi off

bluetooth on for 60 minutes then manually switched off

30 minutes of usage in transit (ebooks / internet / twitter / bt stereo music)

13.00

45% left

That's 45% charge difference. Probably not fully accounted for by wifi/bluetooth toggle and screen brightness. I'm thinking (hoping) that the battery is still getting in shape.
[Nokia Lumia 800] lumpaywk:
Bellow is a reply from the Nokia Discussions forum from a Nokia employee.

Hi all,

we understand that some people have expressed concerns about battery life on the Nokia Lumia 800. Early investigations show that most people are enjoying the full Nokia Lumia experience without any problems and we have not been able to identify a single root cause that would lead to erratic battery behavior at this stage. A software update in early December will make some improvements to power efficiency, while a second update in early January introduces high voltage charging, increasing the Nokia Lumia 800’s battery power from 1300mAh to 1450mAh. These are scheduled improvements and will enhance the overall experience, but are not designed to address any issues that may be occurring with individual products. We recommend that anyone who has concerns contact local Nokia care representatives at their earliest convenience.

BR,

yvonne
[Nokia Lumia 800] maverick1103:
Just seen this on Engadget, at least there notifying us of a known issue, same it will take 6 weeks to get this sorted :(
[Nokia Lumia 800] lumpaywk:
They all show this but they only currently charge to 1300 with an update in january going to boost it to charge to the 1450. I suspect they undercharge there batterys for some reason - probably some stupid legal rules like the ones stopping the use of tethering. I saw with my own eyes the statement from Nokia before they changed it to not mention specifics.
[Nokia Lumia 800] elevation_2:
Nokia claims that not all hand sets are affected so is there any way to check/be sure(Haven't bought mine as yet) which handsets are affected or what is causing it and which are not? Like in the samsung galaxy nexus, the volume bug they have figured out is only on 900 Mhz frequencies. ANything like that for Lumia 800?

Thanks
[Nokia Lumia 800] robinVerdegaal:
EIGHTH DAY

:(

I went on to restart the device due to a blank screen on wifi settings, when the Lumia wouldn't boot up again. After 90 minutes (!) on power with a lot of power button pressing, finally the device would boot up again. Battery level: 72%

:confused:

That's one and a half hour of downtime where I couldn't be reached. Unacceptable.
[Nokia Lumia 800] pontopr:
I have:

Current (discharging): from 188 till 226 mA

Full Charge Capacity: 1511 mAh
[Nokia Lumia 800] davec26:

Il keep it simple, i charge overnight and it lasts untill 7/8 pm

Constant WiFi loads of web searching, pics taken on avarage 7 a day, emails send receive 15 avarage .:D
[Nokia Lumia 800] robinVerdegaal:
What tool do you use to get to those numbers?

EDIT

Ah

Current numbers:

Voltage 3900

Current (discharging) 162 mA

Full Charge Capacity 1517 mAh
[Nokia Lumia 800] X3n0n:
Be aware that event if your phone is 100% charged, the battery will stuck at 1300mAh (Nokia is supposed to release an update to increase to 1450, how it should be).
[Nokia Lumia 800] robinVerdegaal:
Voltage 3.587 V
Current 542 mA
Full Charge Capacity 1513 mAh
Remaining Charge Capacity 393 mAh

Usually 'Current' is around 165 mA, sometimes 250, but in the past 30 minutes it's been showing above numbers. That's three times the usual. Wifi off, bluetooth off, no apps in background.

EDIT

and it's dropped back to 165.
[Nokia Lumia 800] nok_fusion:
for everyone who have "a low autonomy" with the lumia,I did a hard reset couple day ago & now my battery is very very good

in 100%,time remaining show(power save) : 1 day 18 hours

i do a normal use & when i came back to my home,my battery show 40%

I listen music/podcast (1 hour),web(1/1h30),games(20mn),texting+live tile(5),app in backrground (3) etc

so hard reset,and after you have to do a couple of charge/discharge,charge to 100% and let it shut down itself (at 5% it shut down),do this 10 times

U will see some improvements ;)
[Nokia Lumia 800] maverick1103:
Will try that today and will let you know how I get on.
[Nokia Lumia 800] robinVerdegaal:
I did a hard reset this morning, after I charged the battery to 100%.

Right now the battery saving screen says:

Remaining battery: 53%

Estimated remaining uptime: 2 hours

It seems that the hard reset didn't improve anything. Then again, judging from the responses in this thread my battery must be a really, really bad apple.
[Nokia Lumia 800] jhughesy:
haha I like how you did that! :)
[Nokia Lumia 800] stueyboy:
Quick update on battery life from my phone. Here is how it is set up

wifi on and connected / wifi notifications off

3g off / data on

BT off

Location on

date time set to manual

gmail & exchange 30 minute updates

I have the "me" and "friends" live tile

also have BBC and a live weather tile updating (and xbox live, music, nokia music)

I've sent a few texts and made about 3 calls and the phone has been off charge for 5 hours and i have 88% battery left.

the 3g constantly on and not giving priority to wifi is what I think is making the battery drain most on my phone.
[Nokia Lumia 800] robinVerdegaal:
LOL I didn't even notice.
[Nokia Lumia 800] nok_fusion:
It's not just hard reset,u have to do charges/discharges

did u do a couple of charge/discharge? (around 10)
[Nokia Lumia 800] Ashraf Patel:
2 days and 10 hours :). Normal daily usage on 2G
[Nokia Lumia 800] lzyla:
i just unplugged my Lumia800 from charger.

The battery was charged up to 1325 mAh after 7 hours of charging.

Take a look at the attached screenshot too - lumia diagnostic has problems with the battery charge level...
[Nokia Lumia 800] X3n0n:
It's a known issue, Nokia will release an update in Dember and a second one in January to put the battery capacity to 1450 like it's designed for.
[Nokia Lumia 800] robinVerdegaal:
No just two full charges/discharges. Do you use a tool for fast discharge?

Anyway, yesterday I installed 7740 and after that I'm on 32 hours of standby time. That's at least twice the amount I could reach before. I haven't really used it though, which before drained the battery within 5 hours, even with wifi/bt/push services off. Call me an optimist, but I'm hoping 7740 brings significant improvement. :)
[Nokia Lumia 800] nok_fusion:
no i just use it normally

but you can use an app for that,just download "WP bench" you have a battery stress" inside this app ;)

This is what i posted over at the Nokia forums, earlier in the week i was charging my Lumia 3 times per day, now....

Today my Lumia has been fantastic, since my reset I must say its been a lot better, took it off charge this morning, use has been moderate all day, its reporting:

Remaining battery life: 54%

Estimated time remaining: 14 hours

Time since last charge: 12 hours

it was took off charge at 7am this morning, so its almost 13 hours since last charge, WiFi has been on all day, iv used Facebook, twitter, web and email has been on auto every hour, also talked for about 40 mins, few texts, used camera to take 4 images, checked the market too, so not too bad today, device was charged over night via a wall socket.

.... its getting better folks.

Adam.
[Nokia Lumia 800] stueyboy:
Took mmy phone off charge at 7 am this morning and it's now 10:30 and I have 31% left. I've had multiple calls, texts, plenty of fruit ninja and facebook etc. Wifi and 3g been on all day. Granted mostly hooked to wifi but this is pretty good performance.

If you haven't done so already, switch off the automatic date and time as this seems to be the culprit at the moment. I did also do a factory reset yesterday. Thank god for Google contacts!!

So that's 16 hours since charge and showing 8 hours left
[Nokia Lumia 800] RyanMacG:
There is a backup option iirc...
[Nokia Lumia 800] maverick1103:
Its amazing that doing a simple factory reset solves this battery bug.

I was going mental for the last 2weeks now I'm back in love with this phone, though I am getting mine replaced tomorrow as I believe I might have a fault with mine, I've some how used 487mb of data in like 12 days!

Now I've read that when the phone locks it disables the Wifi to save battery, but meaning it then uses the mobile data, hence why I've used so much.

But a few of my colleagues are not having this issue so I'm thinking I might have a defected phone.

Thought??

[Nokia Lumia 800] voluptuary:
the diagnostic app on mine says max cap is 1533 and I have a drain of about 150 with battery saver on WiFi on Bluetooth on and zune playing some tunes on my wireless headset (Sony hbh-is800) while I type this.

I've had one discharge down to about 30% then charged once over night. I let it sit still turned on for a few days unused while I waited for my sim card cutter to come in the mail and now today I've used it all day long, a couple short calls a few texts, with battery saver turned on since I unplugged it from that overnight charge a few days ago and I'm still at 65% the phone says 2 days since last charge and 22 hours remaining. :D I win! Oh I almost forgot I have cellular data off and 3g off since I'm almost always around WiFi.

EDIT: I manually updated my lumia to 7740 that few days ago via the cab method incase that matters to anyone.
[Nokia Lumia 800] davec26:
Im going to hae to try this as my battery is going downhill :) fast
[Nokia Lumia 800] PaulSlide:
The reset didn't work for me. Yes it gave me better estimated battery life but it made no difference in reality. Took it off charge at 0630, it's now 1240 and I have 20% left. My phone is deluded because it thinks that 20% will somehow last a further 5 hours, and that's 3 full charge cycles since the reset. I admit I do use all the phone's features heavily, but still need it to get through more of my working day than this.
[Nokia Lumia 800] davec26:
Hmmm but what is it that's eating the battery up ? I notice pressing back twice or holding back brings up what apps are open but you can't close them down maybe this is the problem the programs are not closing thus eating battery ? I just held back button down again and I have 8 apps open that U can't close so is their an app manager on the market to shut the processes or programs down ?? Maybe that's the answer until Nokia sort it :D
[Nokia Lumia 800] maverick1103:
Where is this back up option??
[Nokia Lumia 800] biggzy:
Dave to close an open app go into the app you want to close from the multitasking window and once in the app press the "back" button repeatedly, you will then be taken back to your homescreen, thus, the app is now closed, repeat above on all unwanted open apps,

Nokia Russia claims that phones sold over here have the battery patch installed. I haven't used the phone long enough to judge, but I certainly don't have any dramatic battery life issues. I don't buy their story, but just in case, let's compare the software versions, shall we?

My phone is running OS 7.10.7740.16
