That really suggests mine has a fault then. I have never seen it say over 14 hours really. I am just turning things off. Do you have facebook/twitter added in as well?

Was 8107 version 11501 then? I am tempted to flash mine clean when the newest roms come out for UK.

What kind of discharge rates do you get?
[Nokia Lumia 800] Radek Hulán:
I was getting around 130mAh discharge rate on idle, now around 75mAh (with 12070 update). So I guess battery should be even better now, but it was good before as well.

059J3G0 variant was distributed directly by Nokia (got an "influencer" phone).
[Nokia Lumia 800] ZeroHour:
Influencer aka the ones they know work :D ;)
[Nokia Lumia 800] ZeroHour:
Hmm it appears if 3G is on after 20-30 seconds it jumps to 250-350ma even though wifi is on. It can go higher but I put that down to background tasks.

With 3G off it sits normally < 100.

I am tempted to flash mine but I am just trying to figure out how much pain it will be getting back up and running since you cant use backups?

Anyone downgraded before? procedure?

Edit: Even in battery saver mode its running at 267ma which should disable background apps and data stuff but leave the connection active.

Updated yesterday morning and this has not improved my usage with 3G enabled. I spend most of my time in WiFi areas so had got used to leaving the network set to 2G, which looks to be what I'll have to go back to.

I'll try a hard reset for the sake of completion, then do more tests with the 3G on and off.

Update Method: Cab

After 2 days with the newest 12070 fw my battery seems to last for 1day~12 hours. Something i have learned to expect from GS, N9 and iPhone 4.

Before the update 800 lasted for around 20 hours, with heavy use it would have been dead in 12 hours. Update before 12070 did nothing, but this was clearly the update i was waiting for. Finally i can use it like a smartphone as i really do love Metro UI, but the battery life has killed it of for me.

On idle the battery drain is now around 75mAh, compared to previous ~130mAh.
[Nokia Lumia 800] Erazor84:
After 2 days with the new firmware: It is better than with 11500 but still not good enough. 12 hours with use, 20 hours with standby ... In idle 253 mA Battery drain.... In Flight Mode 84 mA.

My Provider only has 3G. 3 Austria does not provide a GSM or Edge Signal. So the cause is the 3G Signal ... With Flight mode (around 84mA) the battery life is great!

So let's wait for another Firmware :(

[Nokia Lumia 800] sunny_pirate:
the ligh/dark theme

Updated to latest firmware.

I just noticed that if the theme background is dark, then the drain is around 70-80 mA whereas if it is light then it goes up to 190-200 mA

So could it be that this is more of a display issue...?
[Nokia Lumia 800] mickfarr:
Thats a bit like saying using 2 light bulbs uses more power than 1 light bulb. :p
[Nokia Lumia 800] sunny_pirate:
You could say that :P

What I mean is that the light theme is just so bright across the screen (but I still like it more than the dark one).. Instead of this if it would have been possible to use some wallpapers may be that would be more power efficient.

Also in the battery saver mode, may be they could put in an option to switch to the dark theme automatically.
[Nokia Lumia 800] -obiwan-:
Updated on Friday and battery life is way better than before. Before I had random issues every other day and fully charged phone got drained in 5-6 hours with moderate to low usage.

No this does not happen anymore and I got below 30% drain in 10 hours.

Wifi & 3G on, syncing two mail accounts (one push, one 30min) and having a feed reader Live tile enabled.

However, I currently switching back to 11500 due to the volume bug.
[Nokia Lumia 800] tissotti:
It's not "maybe a display issue" it's a given it will drain way more.

I thought this was kind of a given, and i didn't know some people actually use the light theme. :p

Lumia 800 has AMOLED screen that means every pixel is controlled separately. Black's are actually black, because the pixel is truly off on the black spot.

Meaning on black theme you will have some something like 70% of the screen "off" all the time. Screen is always the part that drains battery the most so this will make a big difference.
[Nokia Lumia 800] Jragar:
my phone idles on 190mAh on 3g, about 7%an hour. this is on the new firmware, ridiculous

[Nokia Lumia 800] Marvin_S:
Is everybody sure that Europe will get this exact same firmware? I know that carriers here kick you off the 3G if you don't actively use it, this might be why even with the new firmware people in Europe suffer from bad battery life on 3G. Maybe we will get a modified version taking care of this issue?

Im just making this up, but Im wondering. Also Im in doubt if I will use the cab sender method or what for zune to show me the update, what do you guys suggest?

Evenings Web browsing and Fruit Ninja (Can clock up 2 hours a day on that mind numbing game). When in the office I am on borderline 3G flicking between No Data/G/3G/H well annoying but we have Wi Fi so hopefully that helps.

Prior to this update my phone would die around 9 hours into my day so this is indeed a dramatic improvement.
[Nokia Lumia 800] asadkhanduhh:
i have the same assumptions
[Nokia Lumia 800] Jragar:
there is a possibility of this ..... you see, each time I connect I get H - I heard that H is when there is data transmitting... and 3g is just idle?
[Nokia Lumia 800] Erazor84:
With every Firmware it Shows "H". Its a bug since the Lumia is on market. After you power on your device, at least for an hour it shows "H". then it shows 3G even if data is transmitted.

that has nothing to do with the new firmware. and i think that this is definately the firmware that also europeans will get over zune.

[Nokia Lumia 800] sunny_pirate:
I got the phone last week. I got all the updates in a cumulative way. (I connected to zune and there was only one update from Windows & one from Nokia)

At 100%, it shows estimated time remaining at 6 hours :( The battery has undergone around 5-6 recharge cycles. Are these figures going to dramatically increase over time (like 1 day+)??
[Nokia Lumia 800] ZeroHour:
Your getting similar times to what I was getting with 3G on. 3G off and it works amazingly. I am hoping that when CV rom's come out they will be tweaked but I dont know tbh. I see people have had a day with 3G on and similar apps etc which makes me wonder if its a problem with my phone or the cab update.

Post cab update 3G drain seems higher tbh.

As above, I would turn 3G off and see what happens. Wifi uses less battery anyway if you have wifi near.
[Nokia Lumia 800] asadkhanduhh:
i was getting like 12 hrs on 100% battery, and was getting fed up. i did a hrd reset, and now i am getting 1 day 20 hrs on 100%.

there must be a toxic app which we download. i do not even use any apps really besides weather and internet explorer and built in apps.

i suggest anyone having issues, to hard reset, and get rid of the toxic app and monitor carefully what you download.
[Nokia Lumia 800] chrissjohn:
Since updating to 12070 using Cab Sender I experience the following:

EDGE: battery drain ~70mA. Battery could last more than 24 hours if needed

3G/HSPA: battery drain sometimes ~70mA but often >200mA. Battery definitely needs charging every night, and best bet is to turn off 3G if not needed.

It is a pity that it cannot maintain ~70 on 3G. Perhaps I will try a hard reset. I hardly use any apps though...
[Nokia Lumia 800] ZeroHour:
Basically your much like mine, when I enable 3G batt drain seems normal initially for about 60-120 seconds then drain goes nuts. I leave 3G off now and I have hunted for toxic apps but its not data usage that causes the drain spike tbh as wifi is enabled and while the handset is active all traffic is routed through wifi not 3g.

When the UK CV rom comes I am wiping to that to see if its an issue with that cab update as drainage is not as heavy with 3G under 11501 although I didnt test that version for too long (just got my phone a couple of weeks or so ago)

Just updated to 12070 through Zune in Spain. It seems Battery is better, brightness bug is solved, but Diagnosis app has not been updated and I could see same information as before.
[Nokia Lumia 800] Marvin_S:
uninstall and reinstall.

Battery life is definetly greatly improved.

However I have found the battery to be draining insanely quickly when having poor 3g signal (drains of about 500) when having a good 3g signal it Always stays aroung 70~90 and lasts about 20+ hours of moderate usage.
[Nokia Lumia 800] pLUSpISTOL:
My non-techie friend has updated his UK black Lumia and says his battery is worse! For god's sake... My girlfriend's UK cyan is fine!
[Nokia Lumia 800] Dust2Dust:
Battery life improved but...

I believe radio is biggest issue. With update 12070 I found that drain is stil humongous when using 3G. Turning of 3G improves batterylife to very reasonable 24 hrs with mid-heavy use. In the past whilest using windows mobile and/or Android this behaviour could be influenced a lot by changing radio-ROM's. some worked better than others
[Nokia Lumia 800] Ray Adams:
I don't use 3G (very bad signal in our country), so I stick to Edge. With new update I really see improved battery life! So it worse updating. Besides battery issue, button illumination now works as its intended to work.

Have no idea why NOKIA didn't test their phones before releasing to market.
[Nokia Lumia 800] jorkobe23:
I get only 10-12 hours a day..

Even when I'm not using it, it drains like 1% per hour.. It's so suck compared to my iPhone 4s..

When I'm using it it drains like hell.... 15% for 2 hours.. What should I do guys? Don't want a hardreset as I don't want to set up everything again
[Nokia Lumia 800] jacksprat:
From what I can tell, 12070 has made a huge differance to my battery life (stock Lumia 800 UK phone, no carrier branding). I applied the update via Zune last night and charged the phone to 100%. I then left it unplugged and untouched overnight for 9 hours, with 3 email accounts configured for push (Gmail, Hotmail & Exchange 2007). Both 3G and WiFi are switched on, but I understand WP7 doesn't use the WiFi connection if it's both running from battery and 3G is on. I'm in central London, so have full signal in my house.

My battery is now sitting at a happy 83%. Previously this would have been down to 30% best. I'll see how it drains during the day today with moderate use and report back.

So far, very happy. :D
[Nokia Lumia 800] Jabbitt:
When I unplug the phone I'm told there is 21 hours of use. How the hell does someone at work get a day and a half after unplugging the previous evening! That was before the 12070 update.

will a hard reset make any difference? I'm close to taking this phone back. EDIT: I lost a few hours typing that post!

[Nokia Lumia 800] Feenik:
If you mean the one displayed on diagnostics screen then its bugged, it always show 21h of use.

i heard ppl say reinstall will fix the problem
[Nokia Lumia 800] Rusty!:
That's because it's an estimate based on recent usage. If you spend some time with the screen on typing, it's going to reduce the expected time based on it thinking you'll be having the screen on typing a lot.

If you were to put it down for a while, the estimated remaining time would go up again.
[Nokia Lumia 800] jacksprat:
As promised, 24 hours since I unplugged my Lumia 800 and the battery is still at 30%. Very impressive.
[Nokia Lumia 800] Jabbitt:
Just a little update on my situation from yesterday. I was so annoyed about the battery life that I phoned Phones4U tech support (whom I bought the phone from) and they told me there telling customers the Lumia gives an eight hour battery life.

They offered some advice but I was telling them tips and tricks before they were telling me! :D

So I thought I'd bite the bullet. I performed a hard reset, let the phone die and then recharged the phoned overnight.

I unplugged the phone this morning and the remaining battery life had jumped from 21 hours previously to 1 day 15 hours! It seems a hard reset is the trick for me. I hope I don't have to do one after every firmware update :)
[Nokia Lumia 800] Wiggy Fuzz:
mine is okay when i'm not in the house. i was out all day, listening to music and my battery ended up at around 76% from full (which i was very impressed by).

but when i went home, by evening the battery had gone down far enough that battery saver turned on. i'd turned off my wifi, too, seeing as i wasn't using it outside, so something leads me to believe it may be my SIM card or something (like it's struggling for signal or something, i don't know. but my s2 on the same network doesn't drop battery life like this does)
[Nokia Lumia 800] jorkobe23:
Oh same situation!

I've emailed the Nokia care several times and they finally asked me to send it to them to fix it but I think it'd be so annoying so I did hard reset last night.

I checked my phone this morning and it shows 95% left and 6 hours time since last charge. Also when I full charged it, it shows estimated time remaining "1 day 17 hours". It was about 13 hours before the hard reset.

I don't know how much it will be drained with real usage but I think when the battery's not being used it definitely doesn't drain as much as before..

I hope my lumia 800 last at least 20-24 hours a day like my iPhone 4s.

I really love the WP7 and the Lumia 800 so don't want to go back to the iPhone though I'm still an apple fanboy (I own a MBP, iPad and iPhone).

I'm planning to get a windows tablet when it'll be released by Nokia later this year so I hope I'll still hold my lumia until the time comes.

:p
[Nokia Lumia 800] Wiesi21:
Battery life

On my Lumia, battery life always was dependent of the data connection switch.

With it disabled and Wifi on (syncing one Google account with push) I get easily over 3 days of moderate use. With the new update, only using Edge (data connection on) and Wifi on, I get nearly the same 3 days.

But as soon as i turn on 3G, my battery life drops to merely a day with light usage.

So I use a live tile for turning on 3G, on an "as needed basis", which is a little inconvenient but this way battery life is great, and for syncing E-Mails and that Edge is fast enough.

Btw. the battery life estimation, has always been relatively wrong for me, so I just compare hours since last charge with battery percentage. With only Edge, I get about 2hours per 1% of standby time, which is much more than I got on the iPhone or any Android phone with the same setting. Don't really know what Nokia messed up with 3G standby.
[Nokia Lumia 800] TehGooner:
My lasted for 2 and a half days on average. All I did was browsing Twitter, listening music and Facebook occasionally, however I do leave my phone to idle for about 8 hours a day though, I don't bring my phone to school.
[Nokia Lumia 800] Jabbitt:
Well after day one I was on 25% by about 21:30. So the phone will last 1 day 15 hours if I don't touch it. With moderate use its lasted. With heavy use it seems I'll still kill it by early evening. I'm hoping that in the next few days things might improve.

Unplugged the phone this morning and its back to 21 hours estimated battery life. How can people be using the phone get 2 days battery life! I'm almost scared to use the phone because the battery will be dead before I get home.

I've barely used the phone, its been unplugged for less than an hour and its already down to 95%

I'm starting to wish I got the HTC Sensation now instead...
[Nokia Lumia 800] maxi14:
i wonder why some people say 12070 update fixes battery issues with 3g on. for me and all other people i know it didnt. lumia after update drains 1% per hour with edge/gsm, but still 4% or more with active 3g. im pretty sure 3g radio software still has a huge bug. btw: wpcentral reports next update could roll out end of march, including tethering and hopefully a new radio software.
[Nokia Lumia 800] paglabhai:
agreed with the above...with 3G on my lumia doesn't last a day but when on Edge I managed to get a full day with average use and 40% battery still remaining...so I am impressed with the new update so far!!!!
[Nokia Lumia 800] bver100:
I'm confused about what people are doing on their phones that is killing the battery. I use my phone fairly regularly during the day, allowing push emails, playing games, reading google reader and checking weather and bus tracker, (and running a few speed tests recently). I've only drained the battery once so far, and that was because i accidentally locked the phone while wordament was running. Other than that, I've never been afraid of running out of battery, and I don't have the new update either (I'm still on 11500). Are people just using the phone ultra heavily?
[Nokia Lumia 800] Boss_Cuco:
Unplugged mine this morning and it turned off near 7 pm...

Made no calls, no texts, no gaming. All i did was facebooking a few minutes and thats it. The rest of the time it was in my pocket, in stand by, with 3G on...

I wouldn't call this heavy usage but i'm still waiting for the update to be released for T-Mobile DE...

For a €400 device it surely feels like something isn't right.
[Nokia Lumia 800] dankspain:
OK I'm just going go for it and give my opinion.

I read in the official nokia forums that the ending calls, reboots issues where caused by fast dormancy and this was a reply by nokia staff. Now, they said it was to be fixed with the next update (12070) and that they were talking to the carriers of those users in an effort to fix it.

Now It might not be it but it seems that fast dormancy when supported by your carrier gives you better batery drainage but If your carrier doesn't your batery is going to behave worse.

In some phones you can deactivate fast dormancy in case your carrier doesn't support it.

Here in Spain the first people to get the new update are vodafone phones which is the only carrier here to have enabled fast dormancy in some of their towers. I believe they get different battery life than for example I do (20 hours on 3g), based on what they say in some forums.

I'm not in Vodafone my carrier is Yoigo which uses Movistar's network and I get around 10 hours of battery on 3g and 24 in 2g.

So this is why I think people get different battery lifes and I hope it gets sorted out with the following updates.

Anyone to back me up on this theory ;)?

PS: it might be completely bs
[Nokia Lumia 800] Feenik:
Run diagnostics and see how much your battery drain while idle? Usually after update its 50-70mAh
[Nokia Lumia 800] Boss_Cuco:
I'm draining a lot more since i'm still on the "old" firmware...

If for any reason T-Mobile skips this update will the next one include this? I think i read somewhere the updates where cumulative...

I find it great that nokia is trying to fix this issue but how can they release this terminal -their flagship- with this autonomy?
[Nokia Lumia 800] maxi14:
@dankspain: your fast dormancy theory sounds good. it would explain why some users report much better 3g standby time with 12070 while others (like me) dont. in austria no carrier is supporting fd, so i cant verify. vodafone in germany and other countries does, and lots of users report great battery life now. anyway: its up to nokia to fix the issue.
[Nokia Lumia 800] Lord Atma:
this is ridiculous.

I did the upgrade for the FW 12 070 and the battery goes bad.

The phone in standby, the battery lasts an average of 24 hours. all in OFF mode to conserve battery power.

I just send some SMS 5 minutes and lost 5% of the battery.

does not exist another solution for this?

hugs

PS: sorry for my english.
[Nokia Lumia 800] DooMMeeR:
I think it is still unusable.

I have had different phones in the past and usage always grew a bit

1. SE P1i had mail synced, twitter and WiFi and 3G on all time

2. Milestone mail, gtalk, twitter, and some other Google Sync stuff

3. HTC Legend the same

4. Galaxy Nexus

1. had easily 1week of usage time though I had the screen on for only 3-4h a week

2. could not last more than 2day under my usage scheme

3. could easily last 2 days

4. does the same but screenusage limits it to about 4-5h screen time

so atm I get 2 days with aroung 4-5h sceen time

BT, WiFi and 3G/HSDPA on with all synced (Mail, Twitter and stuff)

my cousin has a Lumia 800 and buggered me about her problems, so I took it for a ride, factory reset with the new update and all I got was about 12h time before it went off

with merely 3h Usage and no Twitter, only Mailsync

I think that in such a situation it is not usable and she will return the phone to Tmobile for a GSII as they offered it to her because they know about the problem and cannot offer a fix atm.

My dad, a low end user (syncs mail but does nothing with his phone as I would expect my cousin) gets about 4-5days usage out of his Galaxy S2 with BT, Wifi and 3G on so I hope the direction to the GSII won't be a bad one

but the Lumia 800 is definitely no daily usage phone atm.
