I have heard good things about juice defender, but i have a basic question. It says it turns of data during times, or when certain apps are running, etc...
Now, is the data only internet connection? Or will it interfere with my ability to get texts as well, because that would be a deal break for me.
Data is only the internet. The only things that you'll be missing out on are e-mails, which will still come through based on your schedule set up and when you have your screen on.

Heard so much about this app, tried it and took me only a few hours to remove it. When screen is off, it kills data, so basically apps like K-9 Mail that push my IMAP-idle email accounts and poll other accounts are basically impotent.
Plus the interface is confusing with a myriad of settings and no real hold on what settings stick or what not to set. I understand the concept of the app but it's not for me. With stock rom and mediahub-DRM-whatever-process killed off manually, i get by a work day with 50% left over on the train/bus-ride home, more than enough to do stuff before i get home.
I dave been using juicedefender for 3 weeks and it has maximized my batt an overall of 1.4x. The interface is confusing for those that don't spend time and learn it....its granular.

U can set it to fcetch data on certain time intervals and u can get emails like that

I'm totally happy with it - I'm getting a rating of around 1.7x to 1.9x I know I can easily go a full day on one charge. The default setting of enabling data every 15 minutes is enough for me - I don't expect to get emails that are time sensitive to the point where a maximum of 15 minute delay would be detrimental. And I play with my phone a lot so I'm usually waking it up to respond to texts and it reenables data then anyway.
edit: I'm not using any battery tweaks or DRM disabling stuff. I'm stock except for rooting.
You guys and this juice defender. you use more battery with this because it is always running in the background. i get 45 hours without juice defender or a task killer. 1 day of battery pleasssseee i could get 2 if it was left in standby or more. no drm removed. root, cwm, galaxy rom and kernel di18 & blue minimalism
Oh well f me... If you're getting 45 hours that must mean I can get 45 hours because, you know, our geographic locations have the exact same coverage and we have the exact same phone usage patterns. Wow I feel like such an idiot. Thank you. Thank you for showing me that juice defender, instead of increasing my battery life by a good 6-8 hours, is actually killing it by 21 hours...

That's fine - always be skeptical especially when an update comes out to improve performance. I'm about to test the new kernel without this to see if it's worth it. But I know that keeping data off on my Hero tripled the battery life and since having this phone it's definitely increased it. But you can't tell me that I'm losing 21 hours of battery life by using it - and definitely don't try to make me feel like an idiot for using it either.

Im sure its not killing you by 21 hours. prolly your STOCK sync settings though. i only turn it on for a minute or two 3x a day. but go with out it i bet its prolly like 8 hours. think about it when your screen is off it is running. well that is another process that is draining battery unneccessarily. My entire phone is set up like on demand it does what i want it to when i want it to not when it wants too and all of this is acheived with stock settings and checking every app for update frequency settings. I use my phone a lot so i need it to be there.

So for argument's sake, and because I wanted an actual test, I installed your setup based on you're post earlier, andromeda rom, no juice, etc. gmail and facebook sync off. I even went in 4 times throughout the day to turn off running services. I got 11 hours and that was with charging while I was in a vehicle. So I would say about 9 to 10 hours really. TWS was only at 16%. Display was the biggest battery drain at 82%.
So now that I've done this, I can say without a doubt, for me personally, juice defender is really extending my battery life. While running juice defender, I take my phone off the charger at 6am typically and when I go to bed at midnight I still have over 20%. And if I don't plug my phone in, I can wake up at 6am the next day and the phone is still on.
You have a setup that works for you, and I have a setup that works for me. In my setup, juice defender gets me through a 24 hour period without charging. Now that I've got the andromeda rom and kernel, I'm going to test battery life with juice.

45 hours is meaningless when you just let the phone sit in standby the entire time. That's like the car commercials that list higher mpg than they get in the real world.

I have juice defender installed only for it's two toggle widgets. With defender disabled it doesn't run in background, I take advantage of the data toggle widget and I've seen it save as high as 5x's life.
I just switched from the G2, and I don't seem to be getting as good of a battery life. I just went down from 50 percent to 4 percent in 3 hours. Is this normal?
I don't think my phone is sleeping when the screen off. I'm kind of new to android, so excuse me asking, but how do you check if you phone is not sleeping and draining battery while idle? Is there an application or something to check?
One more thing, I just got the new update yesterday. I heard that it's not good to use a task killer, but I'm now using the built in task manager to close apps before I lock my phone seems to be helping with battery life. What are you opinions on this?
Check the battery thread, life seems to vary along among the Vibrants. A lot are reporting 11-15 hours of use before needing a charge.
I read that it's good to put Wifi on never sleep (if you're on Wifi) and use a black wallpaper
Interesting, how do I go about changing the wifi to never sleep? I can't find it in the settings!
Drm running. Go2 apps running- Apps & stop it

If you change WiFi to never sleep, it eats battery like crazy (at least for me, I'm bought with no data, and could barely last a day from when I woke up to going to sleep). With WiFi art to never sleep when charging, I only drain around 40% in an awake day (from when wake up to going to sleep).
Also, when I set WiFi to never sleep, my cell standby usage skyrockets.

Extend battery life
Couple of things I have noticed with this phone
1. Get an app Task manager or similar type apps. There are a bunch of them in the store and here. This will allow you at one click to see what is on in programs and better manage that.
2. Go to the Development section here and read the Bionix 1.9 Thread. It explains how to recondition the battery. Even if your battery is new it is good information understanding how the phone views the battery.
3. If I am out of range or do not need, I stop the wifi and bluetooth. In the menu you can set the settings alot of ways, so you just have to experiment on this. (In home screen, hit lower left button and go to settings)
4. I use my email and phone ALL day (min 10hrs) and typically, I get 15-17 hr of use before it hits 10%
5. Finally, once you are comfortable with the phone, you can load a custom ROM from the Development section. The developers here are very through and Do squeeze the most out of the phone.
Good luck and you will love the phone as I do.

1 - terrible advice - esp with JI6 having one built in (long press home).
2 - This is also in the General sticky
5 - try bionix 1.9.0 (or 1 if you want alt lock screens) and try JACs oc/uv - great battery life so far.
On average use I get close to 24 hours out of a charge using mostly WiFi and enabling no-sleep option, running Bionix 1.9.1 with stock kernel with JI6 modem. I'm also running LauncherPro Plus with facebook widget set to auto-refresh every 5 minutes, the most frequent setting for Google sync, and NoLED notification. I think that is very reasonable.
p.s. I do not use task manager since the operating system is supposed to manage the apps on its own.

I use an app from the market called Y5 (free) to automatically shut down wifi if I'm in an area without it and back on if I'm in an area with it.
Works well for me.
My vibrant is less 23% after being off the charger for 4 hrs. One of those hours was me driving without using it.
Something is wrong. Dunno if it's the update, but something is lilling it FAST - wifi ang gps off the entire time...

I use the living hell out of my Vibrant, and usually it lasts for about 4-5 hours. This being during playing games with brightness maxed, or streaming music over 3G and/or Wi-fi.
If I have a day where I am not doing the above, and just using my phone for emial and the facebook and gmail synching, I easily get over 10 hours before I hit 20%.
All in all I am quite happy with it's battery life. I have just learned to leave my phone on the charger till full charge after streaming music drains it to <20%.
I really should put MP3's on it and test how much that drains the battery compared to streaming.
Either way, I get better performance on battery and memory management then my old (work supplied) BB Bold.
My G2 definitely has more battery life than my Vibrant. That said, once you apply the above mentioned tweaks and especially with JAC's OC/UV kernel, and setcpu set at 200-1000 at conservative, the Vibrant battery life improves quite a bit. Still, its not as good as my G2. But not that bad either..
Keep in mind that the G2 doesn't have to power a billboard sized SAMOLED screen either.
Other than that flash on of Sombionix's ROMs with either of the new kernels and then recondition.
I get pretty good battery life because I don't have 3G in my area so I keep it forced to edge and I don't use bluetooth ever and wifi stays off unless i need it.

People, recondition the battery. It's easy.
Charge it to 100%, keep it plugged in and reboot to recovery, clear the battery stats, drain it all the way, then charge it back to 100% again.
You can start in the morning before work/school and finish at the end of the day. I've never had an issue with battery life on this phone. I can play 6 continuous hours of video/games on this thing and still have battery left.

Hey everyone,
My phone was doing great with the battery life until recently. It might have been some app that got an update that effed me up, but not using my phone all day, I lose battery real fast.
Not sure what's going on, but it's dying real fast!
Any ideas or help?
Sent from Epic 4G
My phone did that from day one practically. I honestly thought it was expected. Later I scrapped all of my apps and reformatted basically. That's when my battery life became amazing. I'd suggest checking all apps for excessive syncing issues. I am pretty sure my culprit was Yahoo Mail. I've since switched to GMail with a bookmark to yahoo if I need to check it.
Hopefully you can find out which app is frying your phone. Good luck.

I was having the same problem a few days ago. I wiped all data and did a factory reset. After restoring apps only (not data), my battery is running like a champ again!
Battery was so bad that it was leaking 1%/minute, it seemed like.
Are you guys checking spare parts, which gives you battery usage stats? It's free on the market. Also, do you get poor coverage in that particular area? Constant searching for service def causes battery drain as well.
sent from my RAZR
You guys never mentioned if you did the airplane mode trick and killed the DRM service. Mine drains about that fast if I forget to do those. Even if I do remember to do them, it still drains much faster than it should but at least I can make it through a whole day if I don't play any games.
in the froyo 2.2 betas they have out for the Epic, there's an option to disable data along with airplane mode and shutdown when you long press the power button. You can still get calls and texts when you disable data..
I thought its a neat feature. It should help you if you're running a 2.2 beta rom.
I think the huge drain is linked to the 50% no signal bug. I would always come home from school with a nearly dead phone every day. I began putting it into airplane mode every once in a while to combat the signal bug and now I come home with 70% left.

Too many factors determining battery life like leaving your 3g on, gps, etc,.or apps constanly updating through your network, like background sync and stuff. Even low signal drains battery
Sent from my SCH-I500 using XDA App
Use spare parts or something and check what is eating your battery first.
Have you been running the same setup, and the problem randomly popped up? Or is it just after flashing your main setup? Also, a lot of apps/settings will drain your battery. First step is to wipe your battery stats, etc. and then check your apps and settings.
I have changed nothing, but going to the ed04 radio. Ed01 was only getting me 5 hours max on a full battery. I have checked everything else.

Use spare parts from the market and also check battery use in about phone under settings. Best way to fix your problem is knowing whats causing it, recalibrating battery helps a lot too. Oh almost forgot , download cpu spy from market,best way to see if your phone is sleeping properly,it should be in deep sleep almost the whole time when phone is not in use.
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.

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.

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.
