I didn't have Nokia drive installed prior to the update but the update installed it and that's when I noticed the major drain on my phone even thou I never opened it. I removed it and I'm currently monitoring the phones usage.

My batter life has turned into complete and utter trash since the update. I hardly talked on the phone and send texts back and forth for a few hours and a little bit of IE browsing and it died within 7 hours. I bought this phone a week after it came out. Is there any chance I can exchange it for another one even though that 30 days has well passed?

Monitoring battery as well. So far, now seems a bit "weaker" than pre-update. I have had the phone unplugged today for 11 hours, and I'm at 28%. Something tells me having wifi always connected at home might be a problem, because that's when the drain is at its most. Usage consisted of 45 minutes of reading news, 1 hour of music, a couple of pictures, and a few app updates.
I've had days pre-update where I've spent near 2 hours on the phone, spent 20 minutes reading news, another hour on music, etc, and have about 40% left after 12 hours of use. Same time, I've had a few poor days as well. It's almost as if my phone is bipolar.

Something definitely wrong. I went to bed last at 2 am and my phone was at 60% . I just woke up 10 minutes ago and my battery was at 25% .
No background tasks
Brightness - low
Keep WiFi on - off
Bluetooth - off
Sunlight screen - off
Sensitive screen - off
NFC - off
3 Emails set to - 1hr
1 email set to - manual
This is ridiculous.

there is an article on the WPC main page about brightness playing crazy. suggested solution is to turn phone off, go into pitch dark room, turn phone on, slide lock screen up and it should now adjust better. It seems that the sensor needs a true dark as low level light for it to adjust properly. try that.

So I have made a few changes and it seems like my battery life has improved.
Turned off all settings in games.
Turned off availability in messaging. (still get texts btw)
Big surprise is the Weather App (Nokia version). For some reason that app reeks havoc on my phone when installed w/ wide live tile. Simply kills my battery.
Also, per Nokia's suggestion I set the phone to Airplane mode for 1/2hr and then rebooted.

If you're still getting poor battery life after Portico, its likely that your unit is defective. My replacement easily gets a full work day of use before and after the update. I'm sure it would go all day from the moment I wake until I go to sleep, but I've yet to try it. All the default settings (location, backup, etc.) are turned on, I've got about ten apps running with background agents, eight email accounts across various services and both Bluetooth and WiFi are turned on. The one differentiator is that I'm not on my phone every second of my work day as some. Still, this is night and day from my previous unit, which could discharge completely from just be on, untouched, for five or so hours.

Mine was down to 46% after just 8 hours of light use. I just rebooted my phone and it jumped back up to 70%, so it does seem like some calibration issue after the update. I"m going to monitor for a while and see if it sticks.

So...hard reset(I'm one of the lucky ones whose 920 doesn't brick) and the battery didn't seem to be good until the nokia updates appeared today and now it seems to be ok. This is without WiFi being forced to stay on. In the four hours since I have taken it off my charger it has gone down 4% after light texting and installing one game. This is what it was like before. Since Portico, I have hard reset twice. First time the battery was not great while this time it seems to be back to normal. I'm not sure why some hard resets result in poor battery life compared to others.

Here's just my two cents on battery after update. My test scenario is not ideal, but here're the details:
- Wife's AT&T 920, updated last Wednesday
- visiting her family in KW, Ontario
- cellular on, data roaming off, persistent WiFi on (not always connected
- moderate use (nav, browsing on WiFi, camera, playing games, no calls or texts, GroupMe)
- background tasks - CNN, Drive, Weather Channel
Here's the amazing part: 26% battery remaining (6 hours) after 1 day 12 hours. I realize that without data roaming on this is pretty useless info, but some people keep their data off because of a low package (my sis in law has 150MB on Fido on her 4S), and this is absolutely amazing battery as far as I'm concerned. My Trophy with data roaming off and non-persistent WiFi doesn't perform nearly as well.

I have every single thin off. My only conclusion is its something with the screen. My phones standby performance is amazing. But once the screen is on I bleed battery. I just lost 12% by making 2 forum posts and reading some reviews of apps in 10 min
