The phone usually keeps 100% charge overnight; and stays at 40% or more by evening.
Last 4/5 days, I notice battery going down real fast - and I attributed it to using stock CM 7.2 (was on squad's ROM for long).
Now, for 2/3 days, I find that the phone will not start / reboot unless power (USB or charget) is plugged, irrespective of battery level. Even rebooting at 80% battery, the phone will not reboot without power plugged in.
I tried going back to one of the nightly builds But, the issue, which surfaced with the latest "stable" official 7.2, has not gone away. So, this is probably not a ROM issue.
Any ideas?
Never keep your phone for overxhargin
Follow yhese steps
1 take a piece of paper
2 fold in a triangularshape with a pointy edge and is also qiute thin at the base
3 now remove your battery
4 u will see three puns where the battery gets attached. Ther put the poinyed tip on the midpin so as to cut the direct contact of the battery
5 let it keep ther and insert your battery wuth only midpin out of contact.
6 now switch on ur phone it shud start after it starts y can remove the piece of paper qmd put the back panel .

No. This did not work. And I now have a new issue. The battery shows zero charge. And battery icon goes red if the usb or power charger is connected. Obviously, the issue is complicated now.
If charger is removed, power is 76%.
Now, I am in sos mode.
Try putting another battery maybe that will work for you.

Try to recharge your battery in another phone, insert it back into yours, go directly into recovery (i assume you have CWM), and delete battery stats. After that, boot normaly, charge it up to 100% in your phone, power off but still hold on the charger for 5 mins. Then disconnect the charger and again go straight to recovery, and again delete the battery stats.
If you don't have another phone to charge the battery in, well, i don't have any smart idea. Maybe you should try Battery Calibration app from the market, to delete batterystat.bin when you are booted. Maybe that could fix the problem after a reboot.
Change ROM >_<

I'm facing this issue too, from past 10 days.
Note: I've calibrated phone many times. Also flashed another ROM but same problem in both ROM's. The below test is done without 3g, no wifi, GPS, or games. 2G/EGPRS is on.
At 1% Android shuts the phone, but the battery is actually 30% when charging in power-off.
Also, when the phone is charged to 100%, I unplug the charger, and battery stays @100% and rapidly drops to 90% in just 10 secs.
Now after 1 hr @ 65% (actual 70%) battery drops rapidly to 15%(actual50%) and stays there for ½ hr.
Here the battery is 4%(actual 45%) and for more than 1-2 hr it slowly goes to 3%,...2% and after 10-15min @1% it shuts off.
The charging is also weird.
The whole usage is just 2 hr in high usage. And for 6 hr in lazy.
All I think is the battery had weakened from all 9-10 months heavy usage.
If there is any remedy please...
Don't know why can't I upload screenshots (using xda app)
Maybe the battery is indeed ****ed up.. the best way to check this is with a voltmeter/multimeter: charge your phone to 100% in power-off mode, and then remove the battery. Check the voltage with the voltmeter, it should be right arround 4.2v. Insert it back and use your phone until android says battery is flat (or powers off, whatever). Remove the battery and check the voltage, if its 3.4v then its not a calibration problem but if its much more than it is, and you should recalibrate your battery.

If all else fails and doesn't work for you, then I believe it's your charger that has the problem. Try using a different charger and see if I could have been right.
Sigh!!! What a relief guys!!!
The 2nd issue (showing 0 % charge) was caused by lint from the paper when I tried the insulate the middle contact hint. Once the lint was removed, phone charged normally; ut the no reboot issue remained.
Now, I moved up from the stable to 16/6/2012 nightly build, and now things are solved. I also deleted batstats.bin manually.
Regarding measuring the battery voltage - how accurate is the measurement in Spare Parts > Battery Status?
What the 3 terminals on the battery? (In other words - the red of the multimeters goes to??? Black goes to??? ) Sorry - my electronics are getting rusty.
<fun>
Another issue is angry birds. They are attracting my kids sooo much that the kids (note the plural) have figured out how to snitch the phone from its high perch, unlock, open the drawher and start angry birds. ;-D So, really not able to check normal drainage. Anyway, I will try measuring the voltage.
</fun>
The middle terminal is for temperature or some kind of electronics inside the battery that prevents from overcharging-i'm not sure, but it doesn't matter when measuring battery voltage. Two terminals next to the middle one are what are you looking for- the one marked with a + is positive and you put your red lead to that terminal. Black lead goes to the negative (minus -) terminal. At full charge you should be getting arround 4.15~4.2v. When flat, it can vary, but i think it goes off at 3.4v - not sure exactly how much it is. And yeah, you're measuring DC voltage here
I've had problems with my battery running Official Samsung stock ROM 2.3.6. Something was just draining my battery. Installation of Juice Defender to prolonge battery discharging didn't help at all, often cleared RAM, rebooting phone etc etc but nothing helped. Sometimes battery drained for a day even though there was minimum usage, 2-3 sms, 2-3 mins of calls and that's it. Since flashing to CM 7.2 official it's been more than 2 days since last time I recharge battery and there's been some heavy usage of my mobile and battery is still 35% :good:
Thanks to all who have replied so far.
Right now, from spare parts, I can see that at 100% the battery voltage is 4233 mV at less than 15% charge. It is 36xx mV.
Also, from spare parts, I notice. Abnormal sensor usage by Ndtv profit, an app for a Tv channels website.
Have removed it.
After last post, fully charged phone. Voltage was 4250 mV. Right now, it is at 85% charge with voltage at 4050 mV. :screwy::
That looks ok to me, either you have a battery leak (an app or the rom) or the battery is dead and needs replacement

It easily looses 15% overnight. With everything turned off.
0 running apps, very few widgets, no BT, no sync, no GPS, auto brightness and even battery saving mode on. Only WIFI is on.
Somewhere Samsung has been promising like 800 hours of idle time. And with current pattern it is going to be 0% in approximately 50 hours without use.
BTW, with WIFI off, it is draining less but if I remember correct it was still at least 1% per hour, which would make it 100 hours. I noticed that battery chart shows Awake quite often, like every 5 minutes or so there is something, not much continuous deep sleep, maximum it was 1 hour of continuous deep sleep in the whole day.
Android OS tops the battery usage list with about 52% at the moment. The Android version 2.3.6. Baseband N7000XXKK5. Kernel 2.6.35.7-N7000XXKKA-CL726566. Build number GINGERBREAD.XXKKA.
I've been using it for a full week now. Could it be related to battery calibration?
What are your thoughts?

I installed JuiceDefender Plus and my battery life is improved. It's not significantly longer, but, I feel better as I can customized it.
Do you have background data enabled? And using the battery usage chart, what is using the most amount of power? The phone itself seems to use more power when the wifi is on consistently. Also, if you're using a rooted phone you might try apps like SetCPU or other CPU controlers to force the CPU to not run as high. Usually helps with increasing battery life.
Thanks for the tips. I have background data on (otherwise even Android Market is not opening).
Still I am not very happy with battery life. Especially idle battery life.
Last night I left it with Sync on and 100% battery. And look at the results:
Look at the screenshots, more than 50% gone in 8 hours. That's 6.5% of battery per hour on idle. And battery flat from 100% to 0% in less than 16 hours without even turning on the screen (with WiFi, Background data and Sync on and nothing else). This is not right.
Do you see similar results?
I am really hoping that ICS with its dual core support will resolve battery issue of Galaxy Note.

What is your wifi sleep policy set to? Try setting it to screen off. I really wonder if wifi can make such a huge difference. I hardly lose 2-3% during the night. I am using the abyssnote kernel now but im sure i didn't lose as much as you even when i was completely stock.
Also use cpuspy to see if your phone is going into deep sleep.
Sent from my GT-N7000 using XDA App
Go to a 2.6.35.14 based kernel to get rid of Android OS eating up all your CPU (its probably not going to deep sleep, check with cpu spy (how much time in deep sleep) and betterbatterystats (check whats using wakelocks) )
I'd install the FM kernel (or similar) and check with cpu spy and betterbatterystats.
Turning off background data (it is required for android market, but after your done downloading apps it can be turned off again) and wifi (for night or when not in use for long time) seems to help a lot.
Looking at those graphs its more of a end user issue than an andriod issue, wifi is enabled and running for the entire 8hrs and i esitmate about 5hrs that the phone is awake instead of sleep mode. which is probably caused by your app or settings.
I have Wi-Fi, GPS, background data and auto-sync on at all times. I lose 2 or 3% overnight (depending on how tired I am ). I do not run any sort of battery app.
So surely it can't be down to OP just having Wi-Fi and/or background data on?
Definitely it will be interesting for OP to switch both off and see what difference that makes.
The graph shows a very consistent drain so it's surely not down to anything intermittent.
OP are you using the original battery? I reckon it might be faulty...

Except it can't be the apps as the 97% OS shows...
Edanfalls, yes using original battery that came with the phone and which says made in Japan so should be solid .
Now after 3 weeks of use, I noticed an improvement of battery life overall, maybe it is that battery calibration that is happening still, slowly?
Now it does not loose so much overnight, last night for example with background data, wifi and even Skype on, it lost about 17%.
It is still draining much more than many people (including you) are reporting. I am suspecting that it is due to very old software (KKA build). I bought my note in Austria and they don't release updates for Austrian phones yet. German ones received already several updates since then and are reporting performance improvements. So this is likely what is affecting my Note's battery life. Will see how it will improve after finally software update comes, especially the ICS one.
I wouldn't think calibration would happen on its own unless the ROM was explicitly designed to run an auto script on reset (doubtful in your case).
I would read up on conditioning your battery and start with that, if you haven't done this already. Then, grab System Panel from market (paid, but well worth it) and use it to pinpoint the culprit(s). With the app, I can always find the offender, see battery usage over 2 hour / 8 hour / etc, and use its widget to *really* auto kill stuff ( by really I mean actually remove stuff out of memory gracefully, unlike many "app kilers"). Good luck.
help please

cant find it on google again ;-( but i explain it to you!
1.Charge your phone to 100% when it is on
2.turn phone off and charge again to 100%
3.unplug on 100% and plug in again (phone is still off)
repeat this prozess 4-6 times (to get your battery more charged)
4.reboot phone and charge again to 100% till your get ful battery message
5.unplug and plug in fast till you get again 100% and battery ful message
6.repeat this till the message of 100% comes fast (should not take longer then 20sec) then your are ready to calibrate
7.open battery calibration from the market and hit calibration button
8.unplug phone (done, almost ;-))
9.let your phone unload till 0% and till it turns self off (dont charge between or connect to pc)
10.charge to 100% again without break between (this is importand then the app will write new battery history)
11.on 100% unplug and your are done!!
sounds like stress i know but this method is realy effective to get more power in your battery! specialy after flashing some custom roms!
notice: cm does not have full battery message like emanoNv4!!

your are done on cm!!
I reached the conclusion that all these calibrations techniques are just a myth.
A Google engineer already stated that the wipe battery stats simply does nothing in terms of calibration. It just removes the data that shows in the battery info (chart and usage by app/hardware). Guess what? That same file is the one that gets reset after reaching 100% and unplugging the phone.
Then no calibration technique explains why on many junky Samsung phones after a phone reboot, no matter if the phone is fully charged or not, the battery loses 5-6% of battery. One reboots the phone to reset it and save battery and instead s/he gets a battery drop. I just find this unacceptable. For much less the iPhone has been massacred all over the news.

Really? So why does it happen even if the phone is charging? Why it doesn't always happen? Why few times the percent even raises?? Why do I get up to 10% drops after a long deep sleep? But I don't get the same drops if turned into airplane mode (well, testing it just now)?
And regarding the energy consumed while booting, it is just a matter of having the CPU at 100% with the highest frequency for a couple of minutes. That barely justifies a 5-6% drop. Antutu battery test drops 27% every hour, less than 1% every 2 minutes. I don't see why the boot should consume much much more energy.
Honestly, it doesn't bother me that much. It was like that in stock rom, it's the same in custom roms, so I assume it's androids normal behavior. Phone's working, battery lasts for nearly 2, sometimes 3 days, so I can't complain about it
Well, in that case you're right not to complain. If my phone reaches 30 hours I must consider myself lucky. And that is with a (2430mAh declared, probably 1700mAh for real) Gold battery. But I don't have Mini/Pop I have a Mini/Pop Plus (actually Next Turbo in Italy), the S5570I.

That's the bug I was talking about. Wait for it to say "Full".
I have had my Nexus 7 (16gig) for a week now, bought it at a local Sam's. Overall I love it. My one complaint is a big one:
The battery seems to drain as fast when the tablet is put to sleep and when it is in use with the screen at 100% !
I powered up the Nexus 7 at about 11am this morning and the battery was at 100% after a full nights charge. I used it to read for about an hour then shut the screen down. It was undisturbed until it about 10:30pm and the battery was completely dead would not even display the charging icon, let alone boot up for about 5 minutes after put on the charger?
Do I have a defective unit or is something not set right? It is still stock 4.1.1.
My Kindle Fire had amazing battery life when in sleep mode, like more than 24 hours.
Cen5
either defective or an app chewing it up.
My battery life is brilliant. I charged it up on Sat afternoon, took it off charger at 5pm. Didn't touch it again until 11am on Sunday morning -- 18 hours sleep -- and came back to it with 93% battery, This sleeps well, unlike my Xperia S
The only complaint I have about he nexus is also battery life, although nowhere nears as bad as the op, it's not even close to the iPad, which I can leave on standby for a week and come back to with plenty of life left, i'm lucky to get 3 days of standby on the nexus.
a lot depends on what you have syncing in the background and what settings you have. I don't use social media accounts much at all and as a result am not logged into them or syncing them. When I shut off the screen I have very little battery drain at all.

Saturday night, I had 54% battery life when I went to bed. The next day, morning , I had 53%. Went to work...left it at home, came back 5 hours later 49%. Used it for a ittle while Went to see the dark knight, came back, 44%.
Now its at 10% after a few hours a constant use.
set your N7's wifi policy to "OFF when Screen is Off". i bet a dollar it helps.
Sounds like an app or something is keeping the system awake. Check battery use settings. Has lots of useful information like keep awake time for different apps and stuff. Not perfect but gives an Idea.
I like to use the app "Batterysnap" so I get real time tracking for battery level, voltage, temp etc and I can view it in a nice graph.
Might want check out Google wallet, sounds dumb i know. My battery seemed to drain more in sleep one day, went into Google wallet (this was an issue on the nexus s early on). Even though i had already set it up the app acted like it was never opened, and would sit there trying setup for first time use and would hang at loading the tos.
Might be in my head, but the device drains at a respectable rate now

I had the same issue on my HTC HD2 running android, turned out it was an app that was running in the background keeping the GPS radio on and searching for a sat lock, disabled it and fixed the issue!
just check your battery stats and see what's keeping the CPU churning.
Mine was losing 1% per hour until I uninstalled facebook and turned off GPS.
I have FB and GPS on mine and only used about 2% overnight last night (about 8 hours).
I had mine on standby for nearly 12 hour and it only lost 1%. I had WiFi and gps turned off. I don't know if this is because I rooted it or not.

Left mine at 99% last night. woke up to it at 98%. battery life is great for me
My battery isn't anything like the OP, but I am a little disappointed in the standby power use coming from a Nook Color running CM7. With just the wifi policy set to "off when the screen is off", it would lose about 2% per day. My Nexus 7 loses about 10% a day with me going in and disabling location services and wifi. That isn't awful but you know what's better than 10%? 2%. I thought the Tegra 3 companion core would actually keep the sleep power usage the same between the two devices.
Better Battery Stats shows that even in airplane mode (which grays out the NFC check so it should be off) NfcAdapterManagerImpl is waking the CPU, about a minute for every hour of sleep. If you don't use airplane mode, then the ConnectivityService uses power too (even if Wifi is off). Finally, if you don't disable all the location stuff NetworkLocationActiveCollector and the associate subservices such as CheckinsNotificationService also eat some battery.
By far the worst potential offender is com.google.android.apps.wallet.pin.PIN_EXPIRATION_SERVICE, which can hold a wakelock for hours at a time that drains the battery at two percent per hour.
Like I've said, the battery life isn't terrible (unless the google wallet service stays running), but it certainly could be better. Battery life while actually using the device is fantastic and I love it.
airplane mode...
i just power off when i know i wont be using within 10 hours.
It really has brilliant battery life. Syncing to G+, Gmail, Facebook

Similar stellar results. Sips juice ever so slowly
At first update 4.3 seemed like a good idea but now ... here is what happened ..
I put my phone on the flight mode then plugged it to the charger and went to sleep then woke up in the middle of the night and saw it fully charged then unhooked it and continued my sleep.
i woke then had my breakfast and went my phone and I saw that it's battery level at 86% and the reason for it was HTC Services !!
Is there workaround to shut them because I really don't need them .

I'm not sure you can disable them, I assume this is a rather vital part of Sense.
However, I'd take this with a grain of salt. Since the update, the system seems to handle battery percentages above 90% differently as part of some weird battery lifetime protection scheme. After the battery reaches 90%, it climbs up to 100% in just a few minutes and the phone acts as if it is fully charged. If you then disconnect it, it will drop back to 90% just as fast. This would mean that if you managed to disconnect it shortly after it climbed to 100%, the actual battery usage in your case was only ~5% instead of 14% and the fact that GSam reports HTC Services as the top battery hog is simply because this app was the only one doing anything in the time frame.
To avoid this behavior, leave the phone on AC even after it reports full battery, it will keep charging the battery, albeit at a slower rate. If you leave it charging longer, it will last above the 90% mark for a longer time.

That has been my experience as well.
I guess we all agree that there's a problem and koniiik might be right .
But I think that there is a bug in one of the HTC Services apps because it remained at the top of battery usage for another day then it went back to normal after the third charge and the battery became stable .
I noticed something that might be good for sharing! Always when I'm charging with 'Power Saver' manually activated it seems that the phone charges better than with this option disabled...With option off(or activated automatically) it charges to 100% but then fast it goes below 90% pretty fast...with option enabled it seems to keep longer before going under 90%...
Does anyone experience the same thing or it's just my imagination?:cyclops:

I have the power saver on nearly all the time and I'm still getting this behavior.
Hi,
I know the specsheet says this phone has a 3090mAh battery, but for example AccuBattery estimates my battery to be 2875 mAh after a month of use.
Is this normal or am I just unlucky and lost the battery lottery?
Accubattery database has errors most of the times. In one month a battery cannot degrade that much with normal use.
Accubattery says that there should be a 3090mAh battery, so the database is correct.
This phone did never show an estimated capacity above 2880mah, meaning it possibly came from the factory like this.
I want to know if this is my device or this is something that all Nokia 8's have.
2875mAh works out to be ~93%, a 7% capacity difference from spec to use is low enough to probably fall into reducing 'full' charge/not charging to 100% to increase longevity, perhaps?
AccuBattery uses data provided by phone to calculate battery wear and the phone reports wrong numbers back apparently.
For my Nokia 8, the battery health status never showed more than 92% (I had AccuBattery installed since day one). That worried me and after a few weeks I did the manual measurement procedure described on AccuBattery website (How to: manually benchmark your battery health) and the result was above 3000mAh.
My hypothesis is that phone hardware reports a wrong number when it comes to battery charge level and that's what ruins AccuBattery estimation. You can see how long it takes to stop charging after it reports 100% charged if you look at charging current. So when it first shows 100% the battery it's not actually full. Also, I used AccuBattery with few other phones. This phone gives me the worst battery life when charged only to 80%, but it's one of the best if I over-charged it to 100%. That makes me think that 80% it's less than the real 80%.

Thanks! I was already suspecting this, as the battery life is excellent on this phone. I usually have more than 50% left at the end of the day, when my Nexus 5x would be nearly dead on it's second charge.

Strange that. Since I used accubattery pro since day one on my note 8 and it showed the full 3300mha . However using it since day one on my note 9 it doesn't show the full 4000mha.

If you want to learn your device's battery situation, you can try to look at some files in root directory. I write some commands on any Terminal App to learn my values. I currently use Qute as Terminal App. For this, i am putting directions you need.
1-Get a terminal app from Play Store ( Qute etc...).
2-Go to the app you downloaded.
3-Enter this command:
cat /sys/class/power_supply/bms/uevent
4-There is a value called POWER_SUPPLY_CHARGE_FULL. This value keeps your real battery capacity. Furthermore, you can glance at other values.
However, sometimes,2 values called POWER_SUPPLY_CHARGE_NOW and POWER_SUPPLY_CHARGE_NOW_RAW shows invalid values but when device charged up %10 to %100, values are calibrated.
The best way to learn your battery values is charging up your devices %10 to %100. After that, go Terminal App and enter the command that i shared.
