Gotta say im experiencing significantly better battery performance since updating. Like having more than 50% left when i go to bed thats having data on all day. I evej bluetoothed 2 albums today which definately hogs power. So im certainly impressed nice work dell.

Agreed.
Still on 70% at bedtime.
2g on all day, some 3g use, a couple of hours browsing on wifi.

Is that compared to 1.6? Then I agee.
They have definitely tweaked the services like gps. Now it takes ages to get a signal. That s the price you pay I guess.
It would be better if we could chose the sensitivity and power consumption of our components. Ie if rather say if I want gps to have a signal all the time or not, or grades between

i made the mistake of using live wallpaper yesterday - hammered the battery (but looked very nice!)
So i'll see how it does today. I couldn't do a full day on 1.6 with regular use so hopefully 2.1 is a step forwards
On the GPS front, I had that issue yesterday - turn off the "assisted GPS" setting and it will improve no end!
yeah a bit more control over power handling could be handy....
after testing without the live wallpaper it doesn't really seem any better than on 1.6?

Live aquarium pity the fish swimming about down't cause enough static electricity to charge the battery
Discovered a batteryhog yesterday:
The mail client eats battery on 1.6. This is the default mail client, not gmail or touchdown.
Had two accounts at 15min intervals, and they caused the phone not to sleep resulting in 10% draining per hour (roughly). Set it at intervals of 1hr, and now I have 97% after 5 hours!
That is an major difference!!

Ok, so what happenned on the 2 instances that this happenned was all of a sudden I lost cellular signal and the phone made a sound and the signal bars switched to a circular sign with the line across it. I put the phone in airplane mode but nothing happenned, within a min phone restarted it self...
The phone is stock. No root or anything like that.
Ps... using the keyboard to type this, and its much easier compard to my old droids kb.

Weird. Haven't experienced that before myself. I have had it lose signal and display the circle with a line through it but it's not very often and only for a second or two.
Just did it again when I went into pandora. I realized its actually not resetting, but the phone freezes up and everything reloads. Including signal and 3G... the screen shutz off and you can't turn it back on until it reloads

Sent from my Epic 4G
I had the same problem on my original Epic. I had three problems in total on that phone.
Samsung's crap coding that caused the phone to not sleep. (fixed after 2nd update)
The phone would randomly restart itself
During calls, the screen would freeze while illuminated. The call wasn't interrupted, but aftwards I had to pull the battery.
In the end I had to exchange the phone for another. Only problem was, the new phone had that couple millimeter gap with the slider. Sprint said it wasn't enough for third exchange though.
Man, this sucks... Just when I put all the apps I wanted on it and got it running the way I want it...
I'm gonna give it 1 more week see what happens, then return perhaps for another epic. I'm pretty sure I'll be sticking to the epic though, i really like the camera capabilities of the phone.
I'm actually going to run 4 tests this week
I'm going to leave the phone untouched from 10:00 to 21:00 and note the percentage in battery with juice defender on/off and also noLED on/off, see what happens... to make it even, i'll just leave the phone in my car, and it won't be used except it's usual email checking/texts/missed calls etc.
my droid unused for that period of time usually was around 80%. it was running a custom rom with 1 ghz kernel as well, so same power requirements i'd say. except epic has a bigger battery.
Battery is pretty bad with the Epic but Im not surprised at all about that. I have about 50% right now with heavy texting, a few phone calls, and listening to music. 8hrs unplugged. I think it would make it to 14-15 hrs easy with heavy use.
Phone calls kill the battery the most I believe.
And I'm using Juice Defender.
Mine was dying with heavy texting, some GPS and browsing within 6-7 hours, no phone calls....
I did a little test today.
When I'm at the police academy my phone is in my car from 1000 to 2100. My rooted 1ghz droid would be at 80% by 2100. it'd get it's regular share of texting/emails and all that I couldn't look at until 2100.
I did the same thing today with the Epic, with juice defender, it was at 79%, so pretty much exactly the same...
tomorrow I'll do the same test with JD off and see if it makes a diff

I have just installed Juice Defender (free version) and using it as installed. I'll see if it helps. I have a question about the status of TRAFFIC, it is listed as "Leave Data/WiFi enabled while >50KB/15s", what does this mean? I can guess that JD will leave the Data connection ON, even if it is scheduled OFF, if the phone is sending/receiving data at a rate greater than 50KB/15s. Is this close?
Thanks

I am having the same problem with my phone suddenly. If I have multiple apps open, such as radio, browser, and facebook at the same time, it seems to cause it to reset itself. It's not a full hard reset, but more of a soft one, screen goes black and everything starts up as if the phone was just turned on.
Maybe it's time for a replacement?
Ok i have posted these comments elsewhere. At the moment I have been lihjtly using my phone and it has been on standby since 1930 (10/2/11) and currently it stands at 80% charge at 1430 (11/2/11)
All I have done is turn flash to on demand (internet-settings-enable plugins- select on demand) I have also got the option to turn my mobile data usage off as well.
The idea came from a blog I was reading about macbook air and why Apple does not ship it with Flash, as it is this software that chews into the Macbook airs battery.
So i applied same idea to the DHD and Voila!
gonna give it a try
thanks btw

I'm trying this now and I've also noticed that apps are loading faster. Let me try the games...

Hey....Nice one....Looks like the phone is faster now...Running CM7...can notice a visible difference...will leave it for some time to check the standby battery consumption

Something I know is the XDA app works better and faster. I don't know why its so...
Cheers from my DHD.
Have just turned plungins to on demand... not sure if it's just me but things do start to feel a tad bit faster/smoother...
What are the implications of changing this setting? Would browsing sites with flash take a slightly longer time to load?
Sent from my Desire HD using XDA App
Well I cannot say about speed difference as it may be anecdotal however, I have now put it on charge this morning as it hit less than 10%. So in total it has lasted 36 hours!!!
I will fully charge again and try leaving the phone with internet data on and see what kind of difference this will make.
Over the past two days I have surfed on the phone, downloaded several podcasts (Freakonomics) listened to them all and done all the usual things with this phone. It now seems to behave how my Iphone 3GS use to act when in 2g mode.
Conclusion:
Impressed and overall consistency of improved battery life is finally available if we follow the Apple way and get the Flash off!!!lol.
Sorry could not help myself
Where can i find the setting to turn off? I would like to try and see if the battery life is better but i can't find the specified setting?

Hey guys,
I'm planning to get a Nexus S (SLCD) version and I would like to enquire on the battery life of it.
My daily usage will be lots of whatsapp, google talk, sms and some surfing. I wonder if I can get through a day with this usage using stock rom.
Thanks and looking forward for your response.
I get two days worth of battery without problem! And yes, I have the SC-LCD (i9023) version. I also have Facebook, Twitter and Google all syncing quite often! I love the battery on this thing, esp. when you compare it to my previous Desire HD

You can use all the apps you mentioned plus have background sync enabled providing that you switch from 3g to 2g.
I use:
Exchange mail push
Gmail push
WhatsApp
Gtalk
Phone quite a lot
When the data is on 2g (or 2g/wifi) I can easily get at least 18 hours.
3g won't let you last the whole day.

i9023 here, using:
- wifi always on (in range for approx 16h per day)
- autosync on

Got one day, but it appeared that Launcher Pro was the battery drain cause, switched back to Zeam launcher, and have two days without problem.
Not talking much, but using email/web intensively.

The results would be bad
I think I could get close to 12 hours. Which is not necessarily bad. However I don't like to live on the edge when it comes to battery - you never know when you will need it...
So I highly recommend you use 2g/wifi if you can. It won't hurt emails or WhatsApp, only web surfing speed would be annoying.

I see. If 3G can last me around 12 hours, I would be very happy already. Guess each person's ideal battery life is different.
I am now getting 3 days with my I9023. The upgrade to 2.3.4 really improved the battery life.
This is with wifi, 3G, a few calls, sms, browsing and about 1.5hrs of music per day!

They really need to get the 2G toggle working. Also, the Nexus S seems to take a while to switch where the connection dies in the middle for a solid 10 seconds or so before it picks the 2G/3G switch up?

When switching from 2g to 3g or the other way around, the connecting always breaks for a few seconds.
This is how it works on all phones usually and I don't think this is a problem.

Toggling is not at all a problems. There are free apps on the market to help you do it quickly or you can go the "long" way which takes 2 seconds and do it via the settings.
Anyway, it is not at all necessary to toggle between 2g and 3g all the time. You should live with one or the other and just switch if/when needed.
I live with 2g/wifi quite well and find I have to switch to 3g perhaps once a month, if that.

The battery life of the i9023 just rocks. I*don't know if it's better than i9020, but my SGS with AMOLED drained much quicker. I get 3 days of battery with airplane mode over night.
Coming from the Epic, the battery life on this is amazing. The Epic ate batteries for lunch (comparatively speaking) even on the best ROM. It wasn't completely uncommon on the Epic to be able to discharge the battery while charging during heavy use.

I can't complain about the battery life on this phone compared to other Android devices.
I get about 30 hours till it dies completely and that's with 20 hours on 2g + wifi, 10 hours on 3g, 90 mins of calls, 30 mins of music, 20 mins of games, 20 mins of streaming TV (Big Bang Theory ), about 4 hours of total screen time, 60 or so sent and received texts, 10-15 mins of web browsing, 1 email account, twitter and Facebook updating hourly.
For new NS 4G owners, or for any new smartphone owner, battery life will increase over time once you stop tinkinering with stuff. I've spent the first few days with the screen on nearly all day, customizing my homescreen to my liking, resulting in only around 6 hrs of life. Last night I hit 17 hrs, mostly on 3g, with 20% left before plugging it in.
Got my LTE upgrade done on my Xoom and now the battery is a joke. I went into settings and disabled the LTE connection, so that now 3g is only used. I also turn wifi on when at home. Currently my Xoom is draining 4ish% per hour while in standby. That means this damn thing won't last a day just sitting there, locked, with no screen on. In Honeycomb 3.0 and 3.1 I could get a days of use with 4-5 hours of screen on time and about 22-26 hours of total unplugged time. Now, under 3.2.2 my battery is totally dead after 18 hours of unplugged time with around 1-1.5 hours of screen use. This is virtually unuseable for taking notes in graduate school after work, when being close to an outlet is impossible.
Any ideas as to what's going on? Tried using Watch Dog and System Panel to see if any apps were going nuts with random CPU usage or RAM usage and everything seems to be in-check in terms of system resource usage. Considering I have 4g totally turned off and wifi enabled when I'm in range of wifi (most of the day) I don't have a clue where this power drain is coming from. Any assistance is highly appreciated given how much I rely on my Xoom for day-to-day use. 3.2.2 seems to have killed it for me.
Please help! Will try any suggestions.
Thanks.

Have you tried disabling mobile data entirely? When I'm in wifi, I disable the cellular connection but haven't performed any in-depth trials on battery life.

Its not just you, mine is the same way it sucks big time. There really isn't anything that I've found to fix it.
I loved how I used to be able more than a day out of a charge...
Anybody have any ideas? Maybe undervolt kernel???

I haven't but this isn't feasable. I use mobile internet for everything and even take notes and such on Google docs. Even though I'm near wifi for most of a given day, I shouldn't be bothered by manually turning mobile data on and off just to have power- mobile data should be mostly killed when wifi is active. That's how this Xoom worked before. A tablet without internet is nothing more than a paperweight to me. 2 classmates with LTE upgraded Xooms are having identical problems. No fixes found yet. Any other suggestions? This battery life is really, REALLY bad.
Tried going a factory reset and battery life is the same, horrid short, running nothing but stock apps.
Any other suggestions?

Same problem here, but I have the mobile network completely turned off and it still does this! Even with the switch to CDMA only!
I will keep reading this thread (only read the about half the posts before posting) so hopefully a solution will show up. But you're not alone in the horrible battery life post LTE upgrade!
I've had my Xoom back since last Wed.
No higher battery drain than previously.
I'm on wifi 90% of the time in home and office.
Yesterday I was all over north San Diego county using 4g. Got home with 60% charge which is about the same as for a prior trip with 3g.
Put your xoom back the way it was. The new hardware sucks the battery a little more. Buy a thunderbolt and then say the xoom battery life sucks. Never charged it during the day before the upgrade. Oh well, that's the price if 4g.

Download Auto Airplane Mode by DON from the market. It will help BIG TIME!! It does just what the title states, it puts the Xoom into airplane mode automatically as soon as the screen goes off. When you turn the screen back it, the data comes right back in 3 -4 seconds and you're good to go!
Also, you don't have to uncheck any settings or turn 4G off.
Update: Mobile data completely turned off, on wifi only with Xoom sitting about 4 feet from router all morning, so wifi signal was strong. This is the first time I've used the device today. Unplugged at 330am my time, its now 130pm. Device battery is at 60%. 10 hours and 40% of battery gone. That's with mobile data 100% disabled, wifi only- can't even get the Xoom to standby for a full day now. At this current drain rate, it would go from 100% to 0% in one day with no mobile data usage, no screen on time and no usage other than syncing Gmail every 2 hours.
Brother who commented above: Thunderbolt will standby for a full day with no screen on time on wifi only and it has under 1/3 the Xooms battery capacity. I should know- my wife has one and it now outlasts my Xoom. That should not be the case.
From my understanding the Xoom has two 3225ish batteries set up in a sequence. My battery life actually seems to be about half of what it was before. Is it possible that one of the two was disconnected during the LTE radio installation and not properly reconnected? Wasn't sure of the details of how the batteries were set up, but if the Xoom could function with the second battery not working, seems like that would precisely half battery life. Anyone familiar with exactly what had to be done internally to upgrade the radio? Looking at the ifixit teardown of the Xoom, the batteries cover the whole backside- looks impossible to do any internal work on this thing without removing them. Any thoughts?
Cheers,
Landon

Same here. Can't get a full day out of it. Hope a fix will be comming up.
Thunderbolt got the he-man battery and modded my otter box to fit. The xoom battery has entered the battery hog realm after the lte radio. As far as I can tell the radio is cdma/lte together. And it uses power even if wifi is on and data off. It's what I would call big brother watcher. Even if your not connected the radio is txing and rxing something. You know it's lojacked!
Sent from my ADR6400L using xda premium
Interestingly enough, removing the LTE SIM card and using wifi only made no improvement to battery life. I'm assuming the new radio is running at 100% all the time without throttling down, even if absolutely no connection exists or there is a string of faulty battery reinstalls in which only one battery is providing power. That might explain why some people seem to have greater battery issues than others.

im glad im not the only one with this problem! its pathetic! im taking my charging cable from my dock with me to work so ill have at least some battery life when i take the train home in the evenings
i to am glad that I'm not alone with this either. I use to charge mine every 4 days with no wifi on and almost no use. Now I get about a day with no use. I mainly use it for web searching and dungeon defenders when I'm home. Horrid battery life for doing nothing. Luckly I mainly only use it at home and am almost always on the dock I got from motor from the upgrade. I use about 4% an hour also with nothing on. Mine is completely stock with no root.
Yahoo mine is stock with absolutely no root or other mods. I guess they knew about the pissy battery life and that's why they gave a free dock. Lol. Still trying to find exactly what's killing the battery. LTE does drain a lot of juice but as I've stated before my wife has a Thunderbolt and per mW of battery power, the thunderbolt is more efficient and that's not saying much. It can standby for over a day with no use fine and it has roughly a little less than 1/3 the Xoom battery capacity. Something isn't right. Its not supposed to be this bad. Anyone filed a complaint/tech request with moto/Verizon? I think its something that we should all do and report what they say here. I have a feeling more and more people are gonna have this issue if they do the upgrade. Maybe if enough of us make some noise, something will be done.

Maybe it's not the radio.
3.2.2 may have some kind of interaction with something you guys were running that's causing wake locks to get stuck
Did you look at Settings:About Tablet: Battery Use ?
(tap on the histogram at the top for another, see if the time spent awake is solid or different from screen on)
I tested this on mine, with the mobile data disabled and lost about 1% battery every hour, this is on par with the performance I had pre-upgrade.
Rooted, stock kernel
I realize it does not help you but you might look somewhere other than the wireless radio for the problem. I unplugged my upgraded Xoom yesterday morning around 8:30 AM. It is now 8:20 AM and my battery is at 66%. I was on 4G for about 2-3 hours yesterday, the rest of the time on wifi. I check and respond to my mail on the Xoom so it saw some use yesterday, though not as much as I normally do.
