ok this is getting a bit ridiculous.. 15 mins of usage (installing all the apps i've uninstalled for testing) with manual medium brightness, it dropped 5% !!

 

and another 6% in 5 min during installing the apps..

 

am taking mine back tomorrow for a replacement. Hopefully the replacement won't be as bad

I've not done thorough testing, but my experience is that battery life is wildly variable. Sometimes it will lose only a few percent overnight, other times it will lose half within a few hours. I can usually make it through the day, but it's very close and certainly worse than my iPhone 3GS. I think it seems to be getting a bit better after a few charges, but I'm still a bit disappointed.

 

Hopefully it can be fixed with a firmware update.

Re: Lumia 800 poor battery life

I'm going to call Phones4U tomorrow to arrange the replacement. Will let you know how it goes.

Would love to find out tho if we are all part of the same batch. Although I got no idea how we can figure that out.

I guess only a Nokia representative could help us out here

Re: Lumia 800 poor battery life

Well, I'm in London like you... but I think one of the posters got his in France, so it'd be a pretty big bad batch if that were the case... unless there's many bad batches out there.

Who knows, maybe it's not a bad batch and Nokia's claim that the majority of people are not having issues is based on them not actually complaining???

We'll find out soon enough when you try your new one out.

Re: Lumia 800 poor battery life

Mine was bought in France indeed, but, the problem is going away. The more times I charge it, the better it goes. After charge 3, the battery went from 100% to 14% in 36 hours.
If it improves a little more with charge cycle 4 or with the sw update I should be able only to charge it every other day.
So, maybe the Fins shipped a bad batch to London after all?

Re: Lumia 800 poor battery life

thats encouraging. Am already 10+ charge cycles in, so I don't think it'll get any better from now on.

Might even suggest Phones4U that it might be a bad batch, see if they can arrange something in regards with that.

Re: Lumia 800 poor battery life

I turned wifi off, and i turned 3g/data off, and it is still on 100% after 2 hours.

My thoughts are:

drivers for wifi/3g data antennas use too much power
drivers for screen use too much power

or faulty antennas. who knows!

Re: Lumia 800 poor battery life

Have you used it at all?

I've noticed that nohing really drains the battery on it's self but rather the crazy drainage happens when you are using the phone, either this is without any connection or with connection.

I'd like to add my name too.
Had it since Tuesday evening and from 100% at quarter to eight on the Wednesday morning it managed to get to about 4ish with 15%-20% battery remaining.
I turned off location based services the next day but that hasn't helped much.
Phone calls use 1% of power for every 2 minutes of call so that would mean 200 minutes of calls would kill the phone (Far below Nokia's advertised one which I believe is close to 6 hours?)
Even when on Standby it seems to gnaw through battery at an alarming rate.

 

Called Nokia Care today though and was put through to someone from the Lumia specialist team, they asked for details and such of what the phones been doing, so I told them what the Diagnostic said.


The Phone claims at all times to be charged to 65535% (which apparently is a glitch, it's the highest number in 16 bit binary or something like that is what the electronics teacher said when I mentioned it.)
I also told her that even though as it only has a 1450mAh battery inside, it claims to be capable of holding 1520mAh of power.

 

Once i'd given her the details she mentioned that they'd had a few people call about the battery, I asked how many and she said about 3 or 5.

 

She then said that the Lumia 800's Battery problems had been made the highest priority and that it was being passed to the people above them to investigate.

I decided that it might be worth asking "Based on the information I've given you would you have any opinion on whether it is a Hardware fault or a Software problem?"
She said she couldn't and that I'd have to wait for the investigation to come back.

She also gave me a Reference number and said that I should feel free to call back at any time to chase it up and they'd tell me if any more light had been shed on it.

Just thought people might want to know this.

Re: Lumia 800 poor battery life

Where have you all been...!!!

Nokia will not admit there is a problem with the lumia.

You lot on here probably make up about 2 % of sales for the lumia.

There are prob 100's of people out there that are not happy with it.

Some complain to their friends.......Some might complain to the shop....some complain on over websites, but there are prob about 50% of people that will just put up with it.

So you on here are insugnifficant to nokia.

 

We had Problem's with the N8 and nokia did not want to know as there was not enough people complaining as there was sales.

There have been minor complaints about other phones, but they did not want to know....as they made up about 0.001% of the sales.

 

So i dont hold out much hope for you lot.

 

I jumpped on the N8 as soon as it was launched and regretted it and had to wait 14 months for an update and that was not a lot of use, so now i use a blackberry.

Re: Lumia 800 poor battery life

Well I got a  about 10 hours of usage out of my brand new Lumnia.

 

I started using it at 1200 yesterday evening with for a couple of hours and at 2000 I used it last, this morning it was dead, not only out of battery but dead. Did not come back even after charging.

 

Fantastic life of battery, now I can go back to the shop and get a new one.

I sent Nokia Care an email about the battery issue of my Lumia. I got the standard response. I replied that I've tried everything and tha the issue still reamins and they replied back by asking for a replacement from the store I have purchased it from.

So I guess that's the only solution at the moment..

 

Unfortunately, I don't feel like my replacement will do any better as it will be probably from the same batch

Re: Lumia 800 poor battery life

Not looking promising.. just setting up the device devoured 4%.. although of course it's too early.. ill need to do a few charge cycles first and then judge it faiirly
