Just to update.. Mine now lasts atleast 3 days..
I have 2 mail boxes configured and sync setup during day time for the same
Light usage of Music player..
normal call usage & browsing.
This is better than pre-anna days..

[swills1980]

The battery life of my N8 drastically reduced after installing Anna without me making any changes to the way I use the phone. 

I had 3g on all the time, widgets to online mode (Social and AccuWeather & 2 e-mail accounts set to retrieve e-mail constantly).

I was getting around a day at best from my battery post upgrade whereas before I was comfortably getting 2 days +. This was with fairly light use- messaging, checking Social apps, some internet browsing.

I have now turned the widgets to offline mode and only use GSM. E-mail retrieval is set to every 60 minutes. I only update my widgets now as and when I need them and I'm over 3 days since my last charge with around 20% left.

It's disappointing that for whatever reason Anna has caused the battery to drain more heavily with widgets in online mode, but I can live with using my phone as above for the time being. Hopefully Belle will see a return to 2 days + battery life even with widgets set to online mode.

That's how it should be, as 3G uses considerably more energy than plain GSM.

I also thought that way, but if you check the N8 device details at Nokia Developer you will read:

GSM Standby Time up to 390.0 hours
WCDMA Standby Time up to 400.0 hours

so, according to Nokia, in standby the N8 in WCDMA (UMTS) does not use more energy than in GSM...

My phone was draining rapidly with Anna unlike with 1.2. I followed arsim's recommendations plus turned off theme effects and now all seems much better.

FYI - I already had wifi scan off, plus only use BT when I need it....

Try what he recommended!!

Yep, but these are somewhat ideal values, when the cell tower is next door.

When the distance is larger, more energy is needed and 3G will cost more.

But I assume you will also have some phone calls occasionally, and then 3G eats lots more of your battery.

So if you want to optimize your battery use, switch off 3G or have energy saving mode enabled. When you do some serious internet stuff, just switch to normal mode.

Might as well shutdown n8 to save battery....:-))

Not sure why this thread is now marked as solved..when it is very clear that there is a bug in anna and people are facing issues...

[Daithidmg]

I have been using my N8 for about 3 weeks now following the Anna update. Unfortunately I can see no real improvements. I find the email worse and the battery life dramatically worse to the extent that the phone barely lasts a normal working day of usage.

This is really poor Nokia a customer should not have to pay minute attention to the use of their phone to ensure acceptable battery life. A solution needs to be provided soon or the previous Symbian version made re-available.

This could be the last straw as far as my Nokia phone loyalty goes! pre smart phone brilliant, N70 Solid performer, N95 Brilliant, N97frustrating but eventually did what it should when the firmware caught up! N8 favourite phone ever until you "upgraded" the firmware!!! aaaarrrrggg  

[Daithidmg]

oh, and this is deffinately not solved!

[thumpererer]

Finally solved my Nokia N8 Anna issues today! )

A little solution I like to call Samsung Galaxy S II dual core processor running at 1.2 GHZ, 4.3-inch AMOLED screen, 8.49mm thick!!! Li-Ion 1650 mAh = Stand-by Up to 710 h (2G) / Up to 610 h (3G)
Talk time Up to 18 h 20 min (2G) / Up to 8 h 40 min (3G) AND GET THIS: its smart enough to switch into 2G AUTOMATICALLY (power saving mode) when 3G is not needed. No menus. No nothing. All by itself.
Ok, I downgraded the stunning camera on the N8, and the aluminum casing, but this thing works. Its soo strange to not be constantly restarting and re-tapping and waiting for things to load and open and 45 seconds to zoom into a picture. Why do we put up with this when the company that we sooo want to support and continue buying products from doesnt even drop a short message in here telling us that they are listening, that they agree there is a problem, and that they are working on a solution?! Would that be so hard?
Sorry Nokia, but your wake-up times in the last years are too slow. You just lost another VERY loyal Nokia fan to Android.
People suffering from Anna I would suggest selling your phones. People see a gorgeous looking piece of hardware and 12MP camera... they will buy it, and then add a few bucks and take a leap forward into new OS's.
Sorry Nokia. I tried to make it work. I fought for you. Stood up for you in a sea of Iphones, but you didnt have my back.

[blitzkid]

That's another loyal fan that you've lost Nokia... Wake up before you lose the rest of us too... Please do participate in the discussion... Reassure us that you're working to solve our problems. Be at hand, when a new problem arises ready to provide help and support. What the hell is Nokia support discussions for without Nokia itself participating in it? All the participation that you do is to delete the messages posted by us users citing one or other silly reasons. Go on... Delete this message as well if you want to. But all I've got to say is you're losing your base without which your company won't stand... :-(

I am with all that disappointed with Anna. 

I used pre-Anna FW intensively:

-reading books, Bluetooth all day long and often might leave it On for overnight + usual calls and SMSing.

During vacation used video and photo camera for hours and still had my phone in good shape next day.

After having Anna installed my n8 went OFF after less than 12 Hr despite I didn't use it for anything except calls.

Turning OFF wi-fy search didn't help much along with disabling 3g.

Do we really need to go deep in science and learning as casual users? 

Unfortunately it is hard or even impossible to get devorced with Anna. I tried to return previous version by using pirate paths and had my n8 died...

I am ready to pay to Nokia reasonable money to rollback to Symbian3. It's a kind of weird to force users to spend efforts and time for having phone ON... Especially when no spare battery may be put in. 

Very-very disappointed with this kind of "improvement".

[ronso]

I also had a dramatic dranage off battery power after the anna update. Then i installed "battery power saving" 1.6.0 from the ovi store and presto. I think i can get almost three whole days out of my battery. That is better then before the update...
Just wanted to let you know.

It MUST NOT be so, don't you see that? A phone should not work like this! A user should not apply magic to make it work as it should after an official upgrade. It should not be restarted now and then. You waste your lifetime dancing around your tricky and buggy sets while the users of other brands just use them in an ordinary way.

And of course this would never happen on your beloved Samsung Galaxy S.

How the chuffing hell can you (Nokia) spend nearly 12 months developing firmware mod that quite frankly shouldn't have been required because it should have been right in the first place and get it so chuffing wrong?

Did you test it? If you did, did you think 8 hours battery life would be acceptable to your users, sorry paid up customers? It begs belief!

My phone is now totally useless to me because believe it or not, I do frequently leave the house for more than 8 hours.

Not to mention the one thing, the one perfect thing you did "OVI Maps". I now can't use on my motorbike because some bright Herbert decided to remove the BlueTooth support.

What are you guys thinking? How can you get away with it?

If I operated like this in my industry, I would be sacked.

What do you mean by "decided to remove Bluetooth support"?

What exactly is not working regarding Bluetooth?

[MontyUK]

the voice guidance is now permanently routed through the phone speaker so you can't hear it on any type of bluetooth head set or car system. No use what so ever if you are on a motorbike or bicycle.

I have just tested and you're absolutely right! The voice guidance is not routed neither through HFP nor through A2DP.

This is an ugly regression.

Nokia pays very little attention to the discussions forums. So I suggest you email Nokia Care complaining about this. I'll send a complaint as well. The more customers do this, the more likely this may be fixed on the next revision.

[lamam]

good

[nokton12]

You will hate me guys when I tell you this, but sorry. I had no problems by updating to symbian anna. And I have no problem with battery life since using anna on my N8.

It's the same as ever, good. so I don't think that there's a general battrey problem coming with anna.
