Sadly, there is still something wrong with the 3G.
After the update I'm perfectly happy with the battery life when I'm using 2G/GPRS. I think I would easily get two days usable time - I'm not sure because I still charge the phone every night, old habits...
But 3G is another story. Battery drain is 15-20% /hour. And what is fun, is that the drain continues if I first use 3G and then put the phone to flight mode! It means that if I want to be sure that the battery last the whole day, I have to remember to put the phone back to 2G mode and reboot it after browsing the web.
For me this is now not an impossible problem. I need mostly email, not the browser, and 2G is good enough for emails.
Separate topic from thread, moved to new thread
I have already tried this before. Even then the battery life is very pathetic. Post the latest firmware update the internet was not working on my phone when connected through the SIM. But after the restore it started working all of a sudden.
I got my Lumia 800 almost a month ago and it was barely surviving for whole day with just normal stuff everyone does. Then after 12070 update (which i forcefully did), i noticed a small improvement in battery - but it wasnt still good. Couple of days back, i restored my phone back to factory settings (but the firmware still updated to 12070) - since then i am getting a battery life of over 40 hours easily with my 3G, WiFi on all the time, did some downloading, radio streaming as well - so may be the trick is to get the 12070 update and then restore the phone to default factory settings - you can take a full backup of contacts and other stuff on skydrive or local system. hope this crazy trick might work for somone.
There's your problem .... You use 1 hour Streaming Internet radio over 3G, and are suprised that it affects battery life?? Internet Radio, like Tune-In over 3G takes a lot of battery...
geez I don't know whats wrong but after the update i get 2-4 more hours than what I used to get (10h) but a weird thing happened yesterday. It went the entire day without the usual drain. I didn't change anything, 3g, wifi, gps, everything on but bt and I used it the same as always but I got double batery life (26 hours).Today it went on the usual draining and all i got was12 hours. Haven't tried on 2g though. Should I do a hard reset?
My Handset is getting worse day by day after the update, earlier atleast it would last my office hours, now without even touching the phone the battery is draining in 6 hours.
Its time for me to throw the handset in home.
Nokia thanks for your software updates which never worked for my heavy priced device.
After a week with the update all I can say it is that I get 14 hours with some music playing and games on 3g (H icon on) with a network company. Since my carrier allows me to use two networks I can use another one and I get 24 hours with the same usage (maybe higher) on 3g (3g icon on), although I see that sometimes when I'm not using the phone it goes into 2g (on both networks). Could this be a fast dormancy issue? I haven't tried a hard reset but i doubt it will do anything.
Got my Lumia 800 few days ago. After today's 12070 update my battery started to show the question mark. I can't understand what's happening, either you solved the problem with "?" either not, because the news you spread is telling that u "did"...
BTW, the diagnostic app is not showing my battery status.
I recently bought a white lumia 800 with latest software.
I do have it for some heavy use. 3 mail sync. Always online with my messengers and such.
But it only last for like 6-8 hours! And the phone is getting hot sometime, without being charged.
So I would like to hear if that is normal battery usage or if I should got mere hours out of the battery?
Lumia 900 unlocked from Rogers network, using on TELUS
Location services: on
Data services: on (set to 3G max)
Find my phone: connected, but 2 options left un-checked
Xbox Live: connected, but all other options disabled
Zune connection: enabled
Background Tasks: 1
Usage pattern: light-to-none (ie, idle all day, light up the screen once in a while to check notifications, no talk time)
IMHO, these are basic settings that anyone should be able to have on and achieve long battery life with. My Samsung Galaxy S was setup the exact same way and the battery would last > 12 hours with light-moderate use, no talk time. In most cases I could actually skip an overnight charge, meaning the battery would last ~ 24 hours on a single charge.
With this phone.. I unplug my phone at 8:30am and by 1pm, I am below 50% charge. That's 4.5 hours of mostly standby time and the phone is already in need of a charge. This is unacceptable. I estimate the standby discharge rate fluctuate between 8-15% per hour.
Compared to what other people have reported they have setup on their phones, I don't think I am being excessive. The discharge rate on this phone in standby is atrocious!
44% discharge (56% remaining) in 4 hours, with no use. Turned the screen on twice: once at 9am and again at 12:30 to check the battery level.
