How do you find you very the best battery life out of your cappy??

Your question is too generic. There are so many factors. Are you on stock or a custom rom?
What kernel/modem are you using?
What apps/widgets do you use?
There are tons of questions, what are you running, and how long does your battery last currently?
I'm running the new phoenix rising 4.0.3 using fancy and beautiful widgets facebook widget and score center.

Off hand I am not sure what the stock kernel is with that rom, but the build you are on is relatively new. Have you calibrated your battery and done a full charge cycle? 100% to dead
Things I do
Turn off auto rotate
Wifi policy set to off when screen is off
Limit how frequently I allow my apps to sync
Turn off mobile data when on wifi
how do you limit the syncing? in 'accounts and sync'? or each app?
Each app should have options for how frequent they sync
Can you explain how to do that? I've tried searching for that option in menu and nothing...

For example fancy widget, click on app in draw, refresh settings, I refresh every 6hrs.
The sports widget probably refreshes allot. I use sports center but I stoped using the widget
I turn of background synching for.my accounts that are on my phone like email and the like.
I always keep the brightness down on my phone and when I.really need to go for a while I will underclock the phone.
Low Screen brightness, No widgets, don't allow applications to "phone home". Gmail is the only thing I keep "sync" on for. Everything else I manually refresh. I also find that weather apps tend to keep refreshing data even after you think you've closed it. I have to keep an eye on Weather Bug (not the widget). I haven't put my captivate on the charger since Friday afternoon and it's now 5 am Sunday and it's still at 35%
Wow. I think I might have damaged my battery. I've tried calibrating my battery a few times and no change. A full charge still only lasts a few hours. I miss the way my battery used to be when I first got it.

I noticed this recently so I'm guessing it might be related to an app but now my Android System keeps the Xoom awake always even with the screen off. Anybody else with the same problem? If so what apps do you have installed? Maybe we can find the common one amongst us that is causing this. Luckily the battery is so good that this isn't a huge issue but I want to fix it.

Having the same issue. Wifi only model, I had wifi off for my 1hr commute to work, and it was awake the entire time.

It's definitely an app or something because I know in the past it hasn't done that at all. Can you list what apps you're using? Or if yours is new enough maybe do a factory reset and see if that fixes the problem?
Either way it's definitely software not hardware.
P.S. I have a Verizon XOOM.
What do you guys mean by the xoom staying awake? the screen not turning off or the android system not going into a sleep/standby mode.

If you go into Settings -> About -> Battery and you click on Android System it will say how long it's been awake. Mine currently has an awake time that equals the total time the Xoom is off the battery - i.e. it never is not awake. The screen turns off fine and the battery usage is low but not as low as if the Xoom was sleeping. When it's sleeping it goes into a lower power state but since Android System is keeping the XOOM awake it can't do that. Other than reduced battery there is no other problem with it though.
Under "Included Packages" for Android System in battery usage the following is listed:
PGM System
Settings
Google Backup Transport
Android System
Settings Storage
System UI
Motorola Location Proxy Service
In the main battery usage list nothing is above 3% usage. 5h 31m on, awake for 5h 11m.
Screebl Pro!
I am long time fan and user of "Screebl Pro" By Key Labs. It takes into account the screens orientation and keeps your device (Tablet or Smartphone) backlit. Its great.
I did a factory reset. The problem seems to be about 99% better. There is still awake time under Android System, but it's verrrrry minimal and not even close to the amount of time the display or system has been on. Leaving the Xoom idle for a while to check once again.
I was sort of dreading that. Please check often after you install apps so we can see if there's a particular app that's causing that.

No apps are over 1-2% after being on for 4 hours. 4 min of awake time under Android System. Looks like the issue is solved.
It turned out being Weatherbug. I uninstslled and reinstalled and I'm back to being able to sleep.

After much testing it turned out to actually be having more than one CNN stack on my homescreen. Don't ask me why this causes this problem but it does. Weatherbug seems to be ok. I hope we get Android updates soon to address these bugs.

It's resolved, but not really solved. If anyone notices an underlying application or setting causing this, please be a dear and update this thread?
I just noticed this today. 100% wake time even with long stretches of the screen off. Happened before installing weathebug. I do have 1 CNN stack on my home screen gonna remove it and test.
Very perplexing. You will see much better battery life if the system actually sleeps lol.
Edit: Yep looks like it was the CNN widget. Took it off the home screen and the Xoom started sleeping. Weird.
I FOUND IT! Listen up folks there is a bug in the latest CNN app that was released recently.
When you have 1 or more CNN widgets and you click on a story VIA the widget it launches a service called BangoAnalyticsService or something and THIS is keeping the XOOM awake. Very easy to test, if you go into Applications -> Running Services -> CNN and terminate just the Bango service you will see the XOOM sleep immediately.
Good news is that you can launch stories using the CNN app (NOT the widget) and it will not launch this service so XOOM will sleep.
I've already reported this issue but PLEASE can you all do the same.
Here is how.
1. Make sure you have latest CNN app
2. Have at least 1 widget on your homescreen
3. Launch a story from the widget
4. Go back to home
5. Go to Settings->Applications->Running Services
6. Click on CNN (1 process, 2 services)
7. Click on BangoAnalytics or whatever it is and click on "REPORT"
Put a nasty comment in there for good measure too!!
Glad at least I know what it is. More people that complain, the quicker it will be fixed.
Workaround: Logout of CNN app if you're logged in. Now it appears you can use the CNN app (not the widget) and it will not launch the Bango service that is the culprit. Let me know if you see other issues.
Is there any concern in "Tablet idle" being at like 3%?
Accuweather Bug
I can confirm that the application Accuweather was keeping my wifi xoom awake. Please note that I checked the in app settings for a run in background or update interval setting which it did not have. Once I uninstalled the problem ressolved.

Just did this. This was the cause of my 100% wake times. Amazing though I still got 9hrs of life on the first 50% of my battery weven with constant awake lol.

nope.
Thank you! CNN widget was the culprit for me as well.
Device keeps to be ON and Heats up really bad and drains battery
Mine Xoom after the ICS 4.0 keeps running Android OS @ 90% use and keeps screen on and drains battery within 2 hours.
After hard reset, it seem to be disappeared, but once I've installed some app updates and minimum apps that I had to use, same thing happening.
So far after removing the DrawEverything app, it works better but have to test it and see further.
It is weird, and seem to me some sort of the memory leak causing device to enter into this state.
I will call Motorola and see if I could get any additional information.
Thank you for everyone posting an updates here.
I live in florida and apparently my phone thinks its 28 degrees outside according to my Sense 3.6 Weather App. any way to fix this?
Well 28° C is about 82° F, so, it looks to me like maybe you're displaying temps in celsius. Try changing temperature setting to display in fahrenheit within the weather apps settings menu.

Ah thank you very much
So I have a question... On op7pro using latest smurf kernel and 7.7 no limits and I'm using a live wallpaper from maxelus demon or AMOLED live wallpaper and even with it set to not optimize battery it freezes every time I turn the screen off so it takes a second or two to start being live again whenever I turn on the screen. Also I have a weather widget that is supposed to update every 30mins that is set to not optimize battery that will not update till I open the app.... Any idea what's going on here?
Hi, I'm new to the x2 pro coming from a op6t!!! Really like the phone, I'm having an issue were when I go from one app to another, the screen brightness varies from app to app!! Say I go into the Google app then I go into facebook app the brightness of the screen goes significancly dimmer upon entering the app!! The two apps I've noticed it happening in most is facebook app and chrome browser! When going from Google app to Google app the brightness stays the same! Any help on the issue would be much appreciated, the phone is set to adaptive refresh and resolution rate and high performance mode is not switched on, eye care or auto brightness are also not switched on, I've toggled the refresh rate settings and Res settings and it's still does the same! thanks again for any help
