Well it seems that battery has improved noticeably. At least Android OS is not at the top of the list anymore of what is killing the battery. More bars is something else and can be just an app and not actually an accurate display of signal strength.

My battery completely drained over night after the 4.0.4 update, maybe the battery needs to calibrate to the OS update? If not Verizon is going to hate dealing with me. Before the update I never had this problem. Any thoughts?

This same thing happened to me last night. It said the screen was the cause of the drain.

Really do not see any improvement in battery life... Wifi reception performance was better on 4.0.2, especially with checking the DBM.

In fact I think google intentionaly lowered
the wifi signal to improve battery life. Could be wrong, but on 4.0.2 DBM count displayed a better signal, which in turn lead to faster browsing, etc...

My wifi experience is completely different. Where I work we have several access points throughout the building. in .2 when I walk straight from one end of the building to the other the wifi could not switch fast enough to give me service. It would loose it's current signal and stay there till I was on the other side of the building still and then would pickup the network again. In .4 it picks up the access points in the middle along the way. I have gtalk messages while in transit so I know it really is getting network access.

My battery life has took a nose dive from 4.0.2. I had the screen on for 1.5 hours, it was responsable for 65% of the drain and I only had 4% left. I was just using the web browser and weatherbug.

On 4.0.2, I could at least get 3 hours with the screen on. Stock Battery.

As for the 4g signal, I think the signal bars were adjusted to match other phones. Not an increase in signal. I have the same db as before, but 4 bars instead of 2-3.

I have screen shots of the signal meter from before and after if anyone would like to see them.

I'm seeing significantly better battery life on my first full day of 4.04.

I am using the phone as heavily as I normally do and at this point in the day, I'm usually down to about 20%.

As of right now, I'm at 5 hours on battery, with 1.5 hours of screen on, and I still have 40% left!

I know that's not great still, but for my usage, it's awesome. I'm pumped.

It might be too early to tell, but I would have to say it improved albeit slightly. I had a little over 8 hours with light to moderate use before it hit 15% remaining. I get much better life on wireless. I am still envious of those whose battery life blows mine away. Honest question, what should be expected from this phone with moderate use on Verizon's network? I can't help but think that I should be getting more life, but maybe it's just not in the cards.

The 4.0.4 update significantly reduced my Droid Maxx battery life. The phone is now dead at the end of the day and prior to the update would be about 50%. This has to be really impacting the Droid X folks that downloaded the update.

Slightly improved. Not much of a difference. Overall, it's pretty good.

I'm waiting on getting a new extended battery for it until 4.1 comes out so it's trained on that version (if it makes a difference at all). And nothing helps battery life like getting an N7. Since I can't put the N7 down, I haven't used the GNex as much.

Version 4.0.4 has improved my battery life so much that I no longer look at the battery indicator during the day. I don't even think about it. I always keep a spare battery in my pocket but haven't used it since 4.0.4 came out.

Why is it that some people have worse, some have seen no change, and some like me have much better battery life with this upgrade? How can the experiences be so different?
