Lumia 800 poor battery life

Re: Lumia 800 poor battery life

Also, apparently WP7 uses data connection instead of wifi when locked as it "uses less power"...I'm sorry but that's a complete lie. There's no sense in using data when there is a wifi right there in range, that makes no sense at all and in no way does wifi use more power than 3g.


This is something I have read a few places, so that might explain why the phone runs out of juice when not doing anything because 3g is being used. I hope that gets fixed.

Not only does it waste battery but wastes data allowance

Re: Lumia 800 poor battery life

So did the Update come "bundled with 7740" or hasnt it been released yet? I have 7740 installed and havent been able to notice any real battery life improvement.

Re: Lumia 800 poor battery life

Those articles are only a few days old so I doubt it has been released yet.

Re: Lumia 800 poor battery life

I was thinking the same thing, but then I noticed one article saying it would come with the WP 7740 update.

Re: Lumia 800 poor battery life

I'm having a very poor battery life as well. I thought my change from Apple's iPhone to a Nokia phone would bring me an improvement, but it's a lot worse, a lot :smileysad:

 

I'm actually avoiding the use of my telephone, because otherwise I won't make it back home and even if I hardly use it, I cannot get a day's life out of the battery. Very bad and this needs to be fixed otherwise, the phone is no good for me.

I have faith in the upcoming update and since in Germany you can return goods that excessively fall short on the company's indication I am not too worried at this moment (if the company fails to remove the defect 3 times).

Re: Lumia 800 poor battery life

Really surprised with the comments, not really had an issue, with"everything" on and frequent use I get a full day, I'm more surprised with people getting 3days from an N8!,  however, there is an update so maybe this will help

Re: Lumia 800 poor battery life

I just switched over from a blackberry bold 9700, which would last me 2 days without charge. I am not impressed by the Lumia's battery life, if the update doesnt fix the issue soon i'll have to consider the iphone4s

Re: Lumia 800 poor battery life

I havent noticed any substantial improvement in battery life since the 7740 update. The battery itself has gotten slightly better over the last 2 loading cycles though. It's still pretty weak.

Re: Lumia 800 poor battery life

I like the lumia and have no real issues with the battery. I also have iphone 4s which like lumia lasts about 2 days on a full charge with moderate use..

Remember lumia is high end phone with lots of processes running in the background. I've found turning screen brightness down and running both options on battery save in settings has helped.

Re: Lumia 800 poor battery life

i just had similar problem with my Lumia 800... it was on full charge before i went out....made a  couple of calls, took a couple of pics. Wifi was swictched off....and after 1 hour, the phone went dead!!!

 

Couldn't even switch it back on after putting it back on charge again....completely dead!!!

 

Phone is running latest OS - 4470....which was meant to fix battery issues...

 

Rang Orange and they now sending me a replacement phone tomorrow.....Just hope its a one-off glitch and not gonna be a real issue with the replacement.....otherwise i might have to go for the Galaxy SII!!!

Re: Lumia 800 poor battery life

I've got the same problem. I got my phone delivered on Friday morning and was told by the tech guy on the phone to let it charge for at least 10hours before first use. I did this.

 

Its now Sunday and ive had to recharge it twice already. Not impressed. 

 

Calling Orange tomorrow to ask them to sort something out, if not, its going back and ill buy another brand.

 

Such a shame, as the phone is great, and ive always had Nokia's. Looks like its game over for Nokia.

Re: Lumia 800 poor battery life

just realized that acording to the internal diagnostics tool, the battery operates on different parameters than in the spec. the battery BV-5JW should operate at 3,7V & 1.450mAh but it actually operates at 4V and when fully charged it shows just 1250mAh. so the overall Wattage seems to fit but at different voltage. don't know if this explains the reason of the low battery life...
