Hey guys,
How much battery life do you get on your X2?
I just installed CM7 and I'm down to 60% after 5 hours of LOW use :/. Could I need a new battery?
Are you doing anything with the settings of the CPU, such as setting minimum frequency, keeping both CPUs online at all time (this might be set via tweaking scripts)?
In fact, ARE you using any type of tweaking scripts (V6 Turbocharger, speedy, etc)?
I don't use any of them and my battery life is pretty good. I also have an extended battery as well, so that helps.
Let the ROM settle in. After two days you should get a better picture of what it's like. Don't forget to do a battery calibration. I haven't even done that yet and have been lucky enough to have great battery longevity. Can also look into managers like Juice Defender. There's also another app I have used in the past that can limit when an app can run. Like limit Facebook from always running in the background and syncing for data. Ithink it'd LGE or LBE security?

Are you using the beta and not the alpha? The alpha has a problem with running the CPU at a high percentage when it shouldn't, which cause the battery to suck.
It is possible that you may need a new battery, but more likely is that the X2 simply has notoriously bad battery life. There are, however, things you can try to help. Go to your settings app, scroll down and click on "applications", and from there, open "running processes". Check out some of the processes. There may not be any, and if you see processes running for games or apps you haven't used in the last few minutes, it may mean that they are constantly running in the background. In that case, you may want to consider uninstalling. Try to use wifi over 3g wherever available. Screen brightness is a major battery killer, and as such, may want to keep it on the lowest setting; I've found it to be the most noticeable improvent in battery life. People are going to tell you to calibrate your battery, but I've done that many times on 2 X2s, never seen a difference. My friends and I agree its just a myth, but there's no reason not to try.
Honestly I don't know squat about batteries, but I remember hearing that the voltage of our batteries is 4.2 volts. If that's a measure of capacity like I think, you can try the app "battery left", which I believe has a voltage meter. If its less than that, maybe you should consider a replacement. Please don't take my word on this though, I can't confirm any of this to be true lol. Maybe someone else can offer their opinion on battery health.
This whole post probably seems like a big collection of thoughts. I'm tokin' right now, took me like 20 minutes to type this.
Hope I could help
To add to theredvendetta's comment, if you have your email set to check for messages, it can really have an effect on your battery. If you set it to never check, I'll bet you will see a difference.

I have nothing of the sort extra installed (CM7 might of had this stuff, but I don't know).

I am using the Beta.
@theredvendetta: I installed the Battery Left widget, and when I go into details it's saying some interesting things.
I'm at 50% battery right now. For one, its saying my battery is at 3787 mV. 3.8 volts I would say considerably lower then the 4.3 it should be. My battery is only ~6 months old, but, for 4 of those months it sat unused, uncharged, and in my hot/cold car. I've only run it down a bit and charged it up 4 or 5 times this week since then.
It is reporting "battery health" as good, but idk.
Under "Accuracy" it's saying the charge reading is "Inaccurate" and the bar is totally red, indicating that the estimation of charge is very inaccurate.
Where can I calibrate the battery? I'll look around under Settings for now. EDIT: It's likely I was only around 60% charged or so when I installed the rom.
And as for background tasks, aside from the default stuff and my few widgets (not a heavy user of those) there's just Facebook+Words with Friends, Songbird, GO Keyboard. Not too terrible, I think.

I probably should have said this to begin with, but when I was talking about the voltage, I meant 4.2 was the charge when at full charge. I can see I worded my original statement poorly, apologies. Try charging up to full, and then check battery left.
When it says "innacurate", its reffering to the battery percentage reading its giving you. When you have cycled the battery once or twice, it will tell you it is "accurate", and the bar Williams turn green. You may notice parts of the bar turn green while first using the app; this means its picking up readings for the percentage of battery you're on at the time. I mean if you're on 50%, it will soon turn green halfway through the bar. After you have completely cycled the battery once or twice, it will stay green and accurate until you reset it or uninstall.
To calibrate the battery, you have to enter Android recovery. I can't remember 100%, but I believe that you hold the up volume button while booting up the phone. It may be down, you can try both. Hold it until you see text pop up that I think says "fastboot". When you see this, let go of the volume button, and now hit volume down until you see text that says "android recovery". If you accidently cycle past it, keep clicking volume down, as the list loops. When you stop on android recovery, press the up volume key. After a few seconds you will see a new screen with an exclamation mark. Press the up and down keys at the same time. A list of options will now appear. Don't use any of them unless you know what you are doing. There should be an option called advanced or something similar. Cycle to it by using the volume keys, and hit the power button to select it. There will be an option to calibrate you battery in there. Itbwill take a few seconds, and after that, return to the main menu and reboot the phone.
Good lord that took me ages to type. There's no hope with dope kids.
I feel like a broken record, but again, battery calibration does not do anything. If there's a chance the meter is off, just charge until your battery's voltage levels off and use the battery fully before charging again.

I agree with you. He asked and I answered. 'Sides, there's no harm in trying it, as there are no negative aspects to it.
Im running cm7 and the only mod im running is the 8 touch points. I do have my screen set to the most dim setting thoough. My phone gets unplugged at 5:30 in the morning though out the day I'll talk send some text might play a few games and usually be on the internet about a hour or so. When I get off at 7pm my battery is usually anywhere from 75% to 69%. A few times it has gone 18 hours and only been down to 52%. Give it some time, CM7 has by far the best battery life that Ive seen for this phone.
Yeah, after clearing the davlic cache and going through a few charge cycles, it seems to of improve greatly.
I'm running CM7 and my phone has been unplugged for 23.5 hours with medium usage including 72 minutes total voice call time and I'm currently sitting at 23%, hence my signature lol and this is a stock battery.
SBF'd from my tasty X2 MAXX
give it a few days but cycle it hard, like don't plug it in until you're below 5%. I have the BH6X (1850mAh vs. 1600mAh) so it's not much of a jump in capacity... your voltage should start out right around 4.2v and drop to about 3.5 when it's close to dead. My phone sucks at telling me how much battery is left, it always has, I typically run this thing dead every day, but some days I'll have upwards of 40% left (voltage is still above 3.8v)
I honestly don't even pay attention to the percentage 'cause I can watch an entire episode of beavis and butthead in HD with the brightness all the way up using software rendering (more power consumption) when I'm below 10% and it won't shut off on me.
it takes me almost a solid two days to kill my battery and I've been on CM7 Beta for a week as of yesterday. at first my battery life was absolute crap, but it has improved... every time you wipe the dalvik it'll take a solid 2-3 days to rebuild it. that uses much more power.
I am prepping for CM7 now. With my mostly stock X2 using Juice Defender I am getting about 1.5 days between charges. When I charge I am about 20% or less on the battery and this is with mostly lite usage. I expect once I make the switch it could take up to a week for everything to level out as it will have to synchronize many things because it will be like having a new phone. When my X2 was new it took about a week to settle in and stop the random crashes. That was also about the time the battery improved from about 1 day between charges. I will write back in a week or two once I have my phone switched and stable.
I used juice defender for awhile but I realized I was really only using it to control data. I just keep a data toggle in the notifications bar. It's really not that much of a hassle to switch it off and it reconnects fast enough. Saves quite a bit of battery power. When I was doing that with my extended battery on liberty I could get about three days.
I am actually impressed with my x2's batt life (although it is a brand new batter when I got the phone a few months ago). I used to have the HTC Desire, and it wasn't the greatest with battery life. My bone stock x2 didn't have the greatest batt life when I first got it, and still wasn't a whole lot better with cm7 installed. But now that I have installed miui on it, and screen brightness is about 70% constant, with wifi ALWAYS enabled. I am going on almost 24 hours now (maybe more??) and I am at 57% with little usage. I've used the phone maybe 2 times today for a total of about 10 minutes talk time, I have no 3g/data, other then wifi when I am at home, so I'm sure that has alot to do with it.
Another tip, that probably everyone already knows, and some people say it doesn't matter, but it seems to for me. ONLY charge your phone when it is less than 10% left, and then make sure it is charged for at least 6-8 hours before you unplug it. I know they say the newer batteries are not effected by this but my wife had the HTC Hero (worst android phone ever IMO), but she would charge it every chance she got, even if it was at 80%. Now, the phone is lucky to hold a charge for 5-6 hours with NO USAGE at all (except wifi always turned on). Granted the phone is older than dirt, and so is the battery, but still. My desire still holds a decent charge considering how old it is. I can get maybe 14-18 hours with no use on it (or very little use) with wifi always on (granted, the phone is bone dead after this time though).
I just altered the cm7 performance settings... back to normal. This combined with a custom juice defender ultimate profile has easily tripled my battery life..

Yeah I've seen nothing come from battery calibration. I have problems with my meter some days draining really quick and some days just normal. If it's bothering my I'll do a reset and that will usually sync it up. I'll try the charged voltage level off and empty thing and see if that helps.
Thanks.

Hi,
I'm currently using JuicePlotter to see how my battery drains over time and this past night I think it drained more than it should (or maybe not).
For the ones who don't know, JuicePlotter runs in the background (of course) analyzing your battery, that too wastes battery juice of course. Thought, the app dev says on his website:
Perhaps the most important feature of JuicePlotter is that - unlike all similar apps and widgets - it's very battery friendly;

So I'm not sure if the problem lies on JuicePlotter or not, I'll have to test it one night without it...
This is how JuicePlotter displays it's graph:
The coloured bands along the graph show your screen brightness, radio usage, charging status and battery temperature. Just scroll around to find precise information and make sense of the different colours.

I went to bed at 4:10 with the battery at 97%. Around 13:00, it was at 89% and I didn't receive any calls/messages/mails/whatever during the night. The WiFi/3G was off all night along with the screen of course. The battery temperature remained the same too. I don't know if it makes a difference but I normally turn off Auto-Sync if the WiFi is off too.
Is it normal to lose 8% of battery juice in 9h in standby? I think it's a bit too much, but I don't know... Does the same happens to you too? What else cloud it be?
Interesting looking app. I've never noticed much of a lose overnight. Just installed the app, will fully charge and give you an update tomorrow.
Also how's the cell reception in your area? I've heard it can drain the battery a far bit if the reception is low.
Sent from my HTC Hero using XDA App
I'll have to do more testing but I think it's the app's problem... Tonight, I went to bed with 83% and it was exactly the same when I woke up...
I fully charged mine last night and turned on JuicePlotter. Still showing 100% this morning. Both in the app and on the phones battery indicator (in the notification bar). Do you know of any other apps similar to this that could be run in tandem?
Weird, Battery Graph also does the same thing...
This needs more days of testing on my part...
My battery goes from 100% - 0% in about 16hrs... doesn't matter how much I use the phone or not.
I have BatteryGraph but the results don't really mean anything to me as it just shows battery life vs time on a scale.
I'll try JuicePlotter to see if I can pin down exactly what's causing my terrible battery life.
I have a feeling it's running at full speed even when in standby but I'm not sure how to check if this is the case. Any ideas?
EDIT: Looking at BatteryGraph I've lost 15% in around 1hr... nothing unusual going on with my phone that I know about... just standard stuff running in the background. Perhaps the battery itself is simply past it's best.

Wow that is terrible, try apps like Taskpanel and when you add programs to your auto kill list the program kills the programs as long as they are running in the background when the screen is off, however if you are on lets say your browser and you don't go to your homescreen the screen goes off into stand by it will not kill the app. Also try draining your battery to the point it shuts down by itself, plug it in let it charge for a bit, boot into recovery wipe battery stats start up the phone or leave it off (your choice) and let it charge fully. Are you using setcpu or OC Widget or anything? If you are using SetCPU make a profile for when screen is off and make it underclocked like 264 Mhz to 480Mhz, or with OC Widget tick the 'use different screen frequencies' (don't remember what it is called since I don't use it) and do the same; I like SetCPU better because when you turn the screen on it switches profile faster where as OC Widget takes its time however with SetCPU do not use the widget it will cause Sense to FC and I'm not sure about Vanilla.
Hope this makes sense since all my ideas are said at once.
::EDIT::

The way I've learned to recalibrate the battery is to let it go down to 5%, boot phone into recovery and wipe batterystats, then power off the phone. Let the phone charge until the green led is on without turning it on. Then turn on and use the phone as usual. Learned it over at modaco. Worked as a charm, and batterytime was improved. I have personally experienced strange batterybehaviour after periods with flashing a lot of roms.

Here.
That's interesting...
Cause I've been playing with ROMs latetly, creating my own, testing hacks and stuff... And most of the time the phone is plugged and the battery is charged, during the flashing process it's using the battery and then it charges again. I also have to leave from time to time and when I get back I continue my stuff, meaning I'm charging the battery at high levels.
I'll have to try that calibrate method...
For now, for the past 2 nights, with JuicePlotter off, I've noticed the battery level did not change at all during the night. Tonight I'm going to try one more time with JuicePlotter on...

Wiped battery stats at 5% last night, let the phone die and then charged whislt off until green light came on. Been keeping an eye on it all day and there has been a noticable improvement.
The phone came off charge at around 2am (so around 12hrs ago) and it has only lost 20%, which is a lot better than I was getting before.
It was probably just due to me messing about with some many ROMs and update zips lately as I tend not to have too much crap running in the background (I use OSMonitor).
I will look into setCPU but I remember trying it before with VR12 and it ended up causing some weird problems meaning I needed to do a full wipe to get everything working again.
Thanks for the help
This night, with JuicePlotter on, I only lost 1%, seems reasonable now... I don't know why that one time I lost 8% during the night. Maybe an isolated case? Something was probably running when it shouldn't, I just don't know what.
2.3.4 eclipse 1.3 in my situation, so I don't understand what causes such ridiculous Phone Idle percentages, is it from ram being abused, an unreliable connection, android hating?
(everything else is commonly below 10%)
wifi is typically left disabled, and i keep it slightly underclocked
what else android, what else!
I swear...the phone never truly goes into sleep mode...it stays awake for large chunks of time doing god knows what...every other phones battery usage graph I have compared it to looks completely different and only has small tiny lines of awake time...mostly when screen on...my x2 shows huge chunks awake when the screen hasn't even been turned on and data disabled for over 4hrs...I don't understand it. Killing my battery
it's a kernel bug, reboot yer phone immediately after unplugging it, every time. or downgrade to froyo (i got my absolute best battery life from froyo

Me?
Yeah I have been doing that since that fix was posted...it helps with life and awake times but it is still horrific compared to other phones...whether I reboot from power menu..power of/on...or whatever....it needs to be fixed...I don't understand why it does this...im about to delete the things that allow it to communicate with moto databases lol...
compare the battery capacity of other phones, most other phones come with at LEAST an 1800mAH battery, this thing is 1500mAH if you're lucky, couple that with 2.3.4's reporting bug and you end up thinking you're going dead much faster than you actually are.
I spend over half my days hovering at 15% or lower according to the phone, but I've also realized that it lies, alot... like my ex.
what does that actually do? =o
like what if you reboot a couple hours after unplugging?
... Christ what was 2.3.4 for if they didn't even get some of this stuff cleaned up
it prevents the idle process from "running away" when you plug it in it essentially disables the idle process, when it goes to re-enable it, it never stops, it takes up CPU cycles and burns the battery down for no reason and it will do it from the moment you unplug your charger/USB cable until you restart the phone.
why? beats me.
I thought you no longer needed to reboot after unplugging on 2.3.4? I did it every morning on 2.3.3, but stopped after updating to .4
I'm confused with this. Wouldn't a phone idle of 70% mean you the phone has been sitting there not being used?
As far as sleep, i use a cpu monitoring app from time to time and it shows my phone in "deep sleep" for multiple hrs when I'm not using the phone; my phone idle will show an equal high %, too.
Sent from my DROID X2 using xda premium
that list indicates power consumption. if I reboot my phone in the morning, idle stays around 10-15%, if I don't, that number skyrockets 40-45% and by 5 or 6 pm, I'm hunting for a place to plug in.
my biggest boosts in battery life came from turning on "data saver" disabling "background data", anytime you can make the 3g radio shut off, you're saving TONS of power
I also just upgraded to a BH6X battery, it was the ONLY way I could make it through a full day when I was working in Cheyenne, Wyoming (cell service there, not so great) I also use wifi as much as possible 'cause it seems to draw less current.
battery life and signal strength definitely have a correlation. the less signal you have the quicker that battery dies.
also, "SuperDim" (available on the market) is a HUGE battery saver, not to mention the fact that the automatic light sensor just doesn't make the screen dim enough, ever. I kinda miss the semi transreflective screen in my G1, I never had to crank the brightness way up to see that one in broad daylight, made the colors funny but at least it was legible. but that's the price you pay for pixel density
I've never had bad enough battery life to try Juice Defender but my roommate uses it on his bionic and it does pretty well. His only complaint is having to load facebook or his browser twice to get data to come back on.

I am getting amazing battery life! Coming from a myTouch4G which would last maybe half of the day, its amazing!
I was at 51% when I plugged in my phone today. I have been using it all day and pretty extensively.
No juice defender either...
This is a mysterious problem for me also. I could have phone booted
up full charge everything that load's up is started. I could turn on airplane mode not do anything else for the day. (So No data no phones) And every-time I bring up screen I will see the amount of apps running go's up (ghost apps)
battery down & less & less ram available.

If you manually tell your phone to go to sleep, you have to long-press the power button for like 6 seconds to wake it back up.
This bug happens on multiple Motorola phones (bionic and d3). I know for a fact that this has been brought up multiple times to Motorola thru customer complaints, Motorola feedback program and carrier complaints. But for some reason they don't care or feel its a big issue. For issues like this, I wish they would unlock the bootloader.
I just installed this:
http://forum.xda-developers.com/showthread.php?t=1246822
Have just been running it for a little bit but what I can see is that it definitely has an impact on battery life (in the good way). My battery seems to be dropping slower.
Thanks to 0vermind two posts above me.
how is the BH6X battery for you?

I cant for the life of me remember but I read somewhere that unchecking the "automatic" setting in "date & time settings" stopped that part from oversyncing and draining battery. I have had mine unchecked for a while and seems to help some. Might be worth a shot. oh I usually 19% +- 1-2% on my phone idle at pretty much all times

That was me in "phone awake" thread.
What it solved for me was the chunks of time phone is awake(when screen has been off) are extremely reduced compared to when the setting is checked.
Only thing is that once in a while(mainly after bootstrapper use or a battery pull) the date/time is messed up. Easily fixed by turning the setting on for 5-15 seconds til it fixes itself and I turn it back off
Ash,
Yea discovered that today when I put in new class 10 16gb sdcard. No worries easy fix like you said super find been using your discovery for a week know working great.
First of all, let me say thanks to Scott for all of his work on CleanRom. I know there has been a lot of discussion lately in his thread about battery usage. Some people are getting outstanding battery life and some people can't make it more than a few hours. I have been one of the people that can't make it more than a few hours no matter what I do. I did a clean wipe of everything before installing the ROM and have even tried to reinstall. The odd thing is my wife's phone does fantastic with this ROM. I finally decided to test things side by side lastnight. My phone should have had the clear advantage because I turned off all syncing options and froze any apps that had been downloaded just to make sure there was nothing running. Meanwhile, her phone syncs like crazy to facebook, email, etc and also has various apps running like weatherbug. I let them both sit overnight and after ~9hrs here are the stats I measured:
Battery % left : 79% (mine) vs 88% (hers)
Data used overnight: 75kb (mine) vs 744kb (hers)
Time awake: 3min 32sec (mine) vs 9 min 42sec (hers)
Time in Deep Sleep: 9hr 19mins (mine) vs 9hr 6min (hers)
Everything points to the fact that I should easily have more life left than hers. I am also attaching a couple of screenshots and the betterbatterystats files to this post. Maybe we can track down why everyone's battery life is so different. Tonight I plan to swap batterys between the phones to try to determine if my battery is the problem.
wow that's pretty good on your wife's phone but horrible for yours especially considering you turned off syncing.
I agree. I have no doubt that her phone could easily still be at 95% or more if I made all of the same adjustments to hers as I did to mine. That is why I am hoping someone on here with more knowledge about this stuff can help to determine what is going on.
It honestly might just be a faulty battery, I was having similar results with mine and my friend's phone, too. I tried multiple ROMs, Kernels, etc. But it slowly got worse and worse to the point that I would go down from 100% to 60% in little over an hour, doing nothing but listening to music with the screen off and auto-sync etc off. I bought a replacement battery, though. And this one is working just fine. You might just be having bad battery luck, or it might be your device, I know some people have returned their Rezounds because of battery life/heat problems, and the replacement generally fixes their woes.
so what did your betterybattery stats report?
Thanks for running this test. It would be very helpful to everyone if you could pinpoint this to a battery difference and I'm waiting to hear your results after the battery swap.
What helped my battery life most was to uncheck the box under "settings -> applications -> start automatically" It has something to do with a task manager. It probably wouldn't explain why your wife's phone does better but it could help both of you get better battery life.
bik- The betterbatterystats file is attached. I see a lot of activity on her phone but very little for mine. The only thing that stands out to me is I have alarmmanager waking my phone for 10 mins and she had it waking hers for only 5 mins. I am not sure exactly what alarmmanager is though.
HTGaming- Thank you for the suggestion but I have already done that as well. I think I have literally turned off everything possible on this phone because it is driving me nuts to burn through battery like this. My OG droid used to us 30% in a day max and now I burn through that in an hour if I am using the phone for anything at all. Pretty much the only thing I had running on the phone lastnight was 4g service which her phone also had.
Another thing you can do to compare the two phones is to install battery monitor widget to see what the drain is on the phones. I used to have decent battery life but ever since the update, it's been worse. The one thing I noticed is that now my phone draws more current when sleeping than it used to. The drain is consistently close to 300ma, whereas before it would be less than 200ma when sleeping.
You have to have the widget on for the monitoring to be active unless you change the preferences.
I swapped the battery's lastnight and here's the results. Hers is still clearly better than mine even though betterbatterystats shows way more activity on her phone again.
Battery % left : 84% (mine) vs 90% (hers)
Data used overnight: 279kb (mine) vs 498kb (hers)
Time awake: 5min 32sec (mine) vs 12 min 8sec (hers)
Time in Deep Sleep: 7hr 58mins (mine) vs 7hr 59min (hers)
Someone posted that they saw different PRIs on phones even after the OTA. Do your two phones have the same PRIs?
damnn thats just weird
Im starting to think that some Rezound batches are differently tweaked than others. My first Rezound had great battery, I would stream music for 5-6 hours on 4G and would still be above 60%. My last two however were completely horrible, on 4-5 hours standby it losses closed to 20% with lil to no use. Same settings/apps as my first Rez. I regret returning my first Rezound, it truly was the perfect phone.
There really has to be a reason why some come with a 3.8 V bat. opposed to a 3.7 V. HTC wouldn't just send out two different types of battery for no reason.
You are missing 1 key info in your analysis, which people always seem to leave out when talking about battery life. The screen on time. I see in in the graphs but it's hard to tell the exact number. Because of the 720p screen on our phones, that makes a big difference. When my screen is on, the phone uses up at least 600 ma/hr. That is conservative, usually it is more like 700-800. We'll assume 600 for now. That's 10 ma/minute. Based on the stock battery, that is 0.6% per minute. So having a difference in screen on time of 10 minutes will give you 6% difference in battery life.
i am also unable to go for even most of a day on one battery charge - and i have 3 extra batteries that were from ebay that dont work even that long...
i do notice it when the screen is on the most - yest i used the gps for an hour and a hlaf without plugging the phone in and my battery lasted about 3 hours after that and died....
very bad....
very interested to see if its the phone or not - great work...
I'll try to answer a couple of questions in here. I got very frustrated yesterday so I flashed an ICS rom to see how my phone did with it. It is equally as bad. This morning, I got into work with 97% life, checked my email for about 2 mins and was already down to 90%. I have the screen display set to 30% brightness too. I am amazed that people can used 2-3 hours of display and still have 70% battery after 10 hours. My screen at 30% brightness probably drains 2% per minute. I think tonight I am going to try to install one of the stock RUU's just to check and see if the OTA upgrade possibly didn't install itself correctly.
HTGaming - I will check the PRI's tonight.
Bluesnake - Both phones were purchased the same day so I would guess they are from similar if not the same batch. Both have 3.7 batteries. Infact when I first got my phone, I could have display on auto, sync everything every half hour, use the screen for random browsing throughout the day and still go home with over 70% left. Somewhere along the line my phone has developed some sort of draining problem though and no amounts of clean installs seem to fix it.
b5fan - Both phones were off the entire night. I think screen usage was maybe 10 seconds for both of them. They literally just sat there on the nightstand while we slept and mine drained 2x faster with nothing running while hers ran facebook, email etc.
I checked the PRI on both phones and they are the same. I re-ran the stock RUU tonight so I will see if that makes any difference. I highly doubt it will but I am running out of ideas.
I guess I was thrown by the screen shots. They both show some noticeable screen time.
the only other thing I could think to check is the email type, push versus pull, and the frequency.

The screen time was probably just from me getting all of the data off in the morning like the screenshots and battery stats. Her email was on push and my email was set to not sync at all. Basically she had a fully functional phone and mine was set to do nothing which is why the battery drain is so hard to explain.
I did run the stock RUU image lastnight for my phone. I put it in airplane mode overnight and it was at 97% when I got up which is a huge improvement. I took it off airplane mode at 6am today and when I got to work at 7am, it was down to 90% so I guess I am in wait and see mode now. I have no email accounts/facebook accounts/ or anything else setup right now. It is only the stock image so there should be nothing draining battery today.
I can confirm the phone is no better now after the clean RUU install. Let it sit overnight and it was down to 80% this morning. I did not even setup any email accounts or download any apps yet. This is just the stock image from verizon.
This is my 4th note. The 3 I had previously the battery lasted a long time. I kept the same battery from the first one in all three exchanges. I took the new battery for this fourth one. Could this battery be a bad one or should I return the phone again for a 5th time. I don't wanna take a chance getting a phone with the problems I had on the other 3.
Just looking for some opinions

Good Lord, 3 exchanges! Wow... try running the battery all the way dead where the phone shuts itself down, keep it on the charger and charge it overnight (or in the realm of 8 hours) while leaving it off and see if that makes a difference. I ran my batt that way once and I'm getting 18 or so hours per charge (depending on how much I play with it).

Reflash your modem, rom, and kernel. See if that helps
I only get about 3 hours of screen time myself. Seems normal for this phone. The huge screen eat up battery fast. Plus if your using LTE, so good bye to your battery.
I don't think you have a bad phone, That's just how it is in my opinion...
so whats your total at the end.. like say.. 5%..?
If you're getting about 3hrs screen time, I'd say you'd be on par with what I'm getting. Some days I can eek out close to 5 hours screen time, usually on the weekends when im at home and on WiFi.

I don't know why you guys are getting such horrible times. With regular use I'm getting an average of 8-10 hrs screen time, depending on what I'm doing. I'm running Saurom RCVI, with Da_g OC Kernel, and tweaked a few of the JKay settings. I recommend charging to 100%, wiping batter stats, and doing a power cycle on it. That's what I did after installing above Rom/Kernel, and battery went from from 4-5hrs to at a minimum 7hrs.

I would like to see a screen shot of that
Fighting battery problems here as well. I'd assume it was normal for this phone, except when I see people posting great times.
1 week old phone. Switched to Saurom yesterday to see if it's any better. Screen regularly at 5%. Usually on Wifi most of the day (and I'm not in an LTE market yet). I set all my synchs (rss, weather) to 4 hours. Others (Twitter) are manual. Only Exchange Email is push.
Using Cpusy & BetterBatteryStats to try to see what's going on. Could be a bad battery - could be that the number I'm seeing is wrong.
Anyway, I'm getting about a 7% drain an hour *with the phone off* ! I'm even rebooting as needed to make sure it's in deep sleep & not 384 (which is very, very annoying). Unplugging the phone @ 7am means a dead battery by 3pm. And if I'm using the phone, it's more like 12-15% an hour (min screen, reading a book). Been charging in the car and at work - whenever I can for now.
Going to try to run some tests on the new rom. Leave phone off for 30-60 minutes & track % loss. Then, maybe put it in airplane mode & try again.
Some weird ones I see to often - Adfree, Maps, Alarm Manager (which I understand can come from almost any of my apps). Oh - tried Juice Defender, no help there either (didn't make any difference at all)
Finally, in the car with Waze (gps), a Podcast Playing, and the screen cranked up for visibility - the car dock/charger keeps the phone about even. On my HD2, a drive to work would charge up like 20-30% of my phone.
Really, really hope I don't need to carry a 2nd battery for days when I can't keep the phone charging.

How often do you get exchange emails? I stopped using push exchange email as it was a huge drain on the battery with the volume of emails I get...
With this phone the screen draws some serious juice, so if your using you phone in the car with the screen on its using about 950mah of juice, so your car charger will likely only keep this phone from losing power, it may not gain any juice, and it may even loose juice depending on charger power and what the phone is doing currently.
This is also why most of us are seeing about 3 hours of screen on time, as while the screen is on its using probably 700-800mah of power. divide that by the 2500mah battery and you can see why...
You can try other programs to try and help with things like background data, undervolting, etc, but that's all going to have a small effect as the "problem" is the screen, its eats up most of your juice. If you want to save battery you need to go after the big thing, the screen, not the little things. However short of reducing the brightness there's not a ton you can do about the screen. It is a big screen, and it needs big power to drive it.

I *think* (need to double check) that the charger is putting out 1A. Where did you get the 950m number from? Is there an appx. chart for different levels of screen brightness (how about 50% for example when in the car? oh - and how much lower is the 5% I use indoors?)
Agree, the #1 thing is the screen itself, which is why I get very confused when I have the large drain with the screen off.
I'll also have to try a test today where I turn on my podcast, but leave Waze off - and turn the screen off while it's charging in the car.

950mah is an educated guess. If you have root you can run this in a terminal to see how much power you car charger is giving the phone... (su first)
cat /sys/class/power_supply/battery/batt_current_adc
I usually get about 9100 for a result, which is 910.0 mah. and my phone will charge barely if I dont have gps going (screen on). if screen is on and gps is on the phone will slowly discharge, so that puts the phone power usage at about 900mah with screen on, so maybe 950 was too high of a guess. So when the phone screen is on, your using a ton of juice for such a small battery.
If I use just a podcast app and the screen is off the phone will charge much faster while in the car. If I have google maps running, it stays almost even...
You could even calculate your usage. She how many minutes your were driving with the screen off and the phone charging and note the amount of battery% gained in those minutes. You'd see a huge difference in charging times with the screen off. In my 50 minute commute to work, I gain about 20% battery charging with the screen off... With the screen on, I see almost nothing.
Seems like some days are better than others.

My Nook is 10.5 months old and I have recently noticed it only hold charge for 2-3 hours.
I am still running 1.40 and rooted so I could block OTA. I haven't done any other modifications to the tablet.
Is this a common problem? I need to charge this thing everyday now, where before I could go several days without recharge.
Thanks for the help.

haven't used stock in a long time, but is there an option to turn wifi off when the tablet goes to sleep? ur wifi might be sucking up power continuously if it doesn't shut off.
Yes, that is correct, Wifi can be switch off. And I have done that. But the drain has become very significant.
I am considering going for a warranty repair, but my guess I will get a refurb with another weak battery, and hassled because I have rooted and blocked OTA.
Are most folks just running off their chargers?
If folks have bad batteries are they replacing them themselves?

you can attempt to request for a new nook tablet placement. After two refurbished replacements with the same problem as my original NT. they sent me a new Nook Tablet and so far so good. It's worth a shot.
Came off the island today and went to the big green city. Stopped at BN and did some talking with them and also to the service center at the same time. The service center said they would send me a refurb. My 3-4hour of run time is way under the 11.5 hours you should get for the e-reader mode only. That fella felt like the battery developes memory and needed to be fully discarded to combat that occurring. I can not find any technical document that supports this idea. There are not NiCad batteries.
Anyway if I send my tablet in I will end up with 1.4.3 instead of 1.4.0.
When you get your replacement
Once you get your replacement, it's a good idea not to charge it until it show very low percentage on any nicad rechargeable batteries. When you charge it, don't remove it from the charger until it reaches 100%. Also don't have a habit of plugin it in when finish using it, plan ahead so that you can have a fully discharge battery before recharging. Your NT battery charge will hold a lot longer threw time if you do it this way. You also can try this app to see if it works.

Good advise, thanks,
I put in some effort to side load the battery stats reset software and found a application call: Battery HD. I loaded this app instead. It provides a graph of the charge and discharge rate. From the graph I can see that my battery is OK. I became aware of some funnies going on when I woke up at 3 am and saw the display on. With the discharge rate as specified I now believe I have some application causing me trouble. I don't have much on the table, Titanium, MX video, Amazon apps.
I shut the unit off last night and it came back right to the same charge. Tonight I will leave it on and check the graph to see if there was an load and when. The application has a gross report on the power used separated by function instead of application. It also has a calibration test that tests the three main functions and reports the discharge rate.
Anyway, I will post what the nightly current hog is if I can find it.

My friends NT has been having issue with screen turning on by itself. Seemed to narrow it down to aldiko app. Not sure why it's happening. Performed a clean install of CM7 and issue came back. I keep thinking it's hardware related, trying to convince him to try a different ROM, but he's stuck on using CM7. If you find a reason for your tablet screen turning on let us know so maybe I can help him get his issue resolved. Thanks...

That's actually bad advice for any lithium based battery - like the NT's lithium ion battery. LiON batteries don't like to be fully discharged and they don't like heat, especially heat when they are fully charged. That means avoid full discharges and avoid charging it to full every time, and do charge the battery more frequently (keeping the charge level between 20% and 80% for example). Partial discharge on LiON is just fine; they don't suffer memory effect.

I have said it in past post, I need glasses. I totally missed this part while reading "There are not NiCad batteries" the word not always gets me.Sorry about that sgschwend. I did not even know, thanks for the info update.
Well, I always appreciate advice, my view is that it becomes a starting point and it is up to the reader to combine it with a working course of action.
As to phantom startup/turnons I checked last night and there wasn't one. I will continue till I find it. The summary screen does say what type of application is turning on so that should help. The only gotcha will be if the battery application changes how the tablet works to the point that the issue will not occur. I don't think this is very likely.
The battery application (battery HD) makes a nice graph so you can look at the slope and see what is going on, it also lists the run time for various activities based on the current battery charge. Interesting to note the Nook charger overcharges a bit and the battery does warm up some. When it cools down the charge is just under 100%. This is not an ideal situation, it would be better for the charger to slow to a point that the battery temperature is not elevated near the end of its cycle. Splitting hairs perhaps. My discharge rate matches the tablets specs even with the battery application running.
Second day of monitoring the device operated correctly. I did check and found that I have a Titanium backup batch job setup to run every day a 3 am. Which coincides with time I observed the device display turning on. I will move the time and see if the issue moves too.
Steve
Also turn off push notifications that certain apps have. They suck up a lot of battery. Install the Better Battery Stats app (search xda for it). Won't have to pay unless you want to. Monitor the partial wake locks to determine what apps are using battery during sleep.
I have a similar problem, i got a nook with cm7 and the battery doesn't last at all, i charged it yesterday and let it all night without touching it to see how long would it last and after 12 hours i got 30% and it says 70% of the battery was drained by the andoid os, it says that the processor was working for 2hrs!
i got it and stared looking for an answer to this problem and in less than 10 min it has drained 4% of the total charge, this didn't happened with the stock firmware so I'm thinking about trying jelly bean and if it doesn't get better i will have to go back to the stock firmware
Hwong, I think you hit it on the head. Last evening my NookT had a much higher current draw, loosing 20% in 12 hours. I saw this when I checked it a midnight. I had left the Nook with the battery monitor application in the graph mode, likely running as an active application instead of a "monitor" mode. Titanium Backup did run last night but it runs for such a short period it did not even show up on the graph.
So I really don't know which application or notification is causing me a problem but the issue I have had is like loosing 20% of my battery in a 6-8 hour period. Which to me looks like an application is running that shouldn't and the time I observed the screen on would do it too. As I started this post I am still on 1.4.0, rooted, OTA blocked with hidden commands.
I did a hard factory reset and wipped the caché, now my nook has been charged for 2 days on sleep mode with the wifi on.
I believe the problem was caused by an application, i believe it was the launcher and theme i was used, i re-installed it yesterday and the tablet started to drain battery quickly again so i cleaned the data used by them and uninstalled them.
The battery monitor widget use to say my battery would last 2 hrs of video playing, now it says it should last 8:30, closer to the 9hrs promissed by B&N.
It all about old sins. I found that I was jumping around in the normal Nook UI and not using the back button. So several things were still running in the background. Even though that little darling looks the same, that background stuff is a killer. I did a quick test with the battery monitor by leaving it in the graphic mode and sure enough the discharge rate went up 400%, just a dumb graph in the background plotting Voltage versus time. When I use the back button on the application graph, the current draws goes to near zero.
It really does a nice job of standby or sleep.
Maybe this will help.
You could use titanium backup to freeze the apps that you think could be causing more than usual battery drain and maybe narrow the issue down?:fingers-crossed:
