Under the battery usage screen the information displayed isn't correct. Right now it says I been off battery for 30 minutes and it has actually been an hour. It was doing the same thing yesterday so I wiped the battery stats in CWM but things are still messed up. Any suggestions?
I'm running Unnamed 1.1 with Entropy's kernel.

you must've powered off/powered on the phone in that time. sometimes when i turn off my phone, even if i don't plug it back into the charger, my battery time will reset itself to zero. same thing can happen when you boot into recovery, i.e., to wipe battery stats (even though that does not do anything on our phone).
I never rebooted. That is what was so strange. The other night there was nearly an 8 hour discrepancy. It took about 3 hours for the battery to show it had been running for an hour. The screen on time was also wrong, showing the screen had been on for 1/4 of the time it had actually been on.
If you wipe battery stats it does reset the battery use screen to zero when the phone reboots. It might not be useful for much, but with the timers reset to zero I could at least see if everything matched.
Bloody hell, my phone has been rebooting itself. I'm pretty sure that is why the stats are all messed up.

should i wipe battery stats i switching from extend. battery to stock. or only when switching roms? when does this matter?
[Also i know this doesn't belong here but my PC is really slow do easiest way is to ask: is there someway to search all my posts at once as they're becoming hard to keep track of ?]

I switched back to my stock battery after my extended died. I wiped battery stats, wiping stats when flashing new roms is recommended.
Wiping battery stats is never really considered an essential thing to do no matter what. It is nice though to do. I suggest it when you start realizing crap battery life on one ROM/kernel compared to the last one. The suggested way is to wipe it after installing a new kernel and as well as when you swap batteries. Other than that, really no need to in my eyes.
I wipe after every new ROM install, period.

This is when I do it also.
Digging up a thread here, didn't want to waste a new one.. But I have the OEM Extended Battery and I tried wiping my battery stats.. Charge full, reboot into recovery, wipe stats, unplug.. After this I noticed that my battery said 93% even tho the charge light was green.. I drained it until it turned off and charged again overnight.. In the AM, light was green, i turned phone on and its still showing 93% even though it was green. Any ideas? Did I lose that 7% forever?
Sometimes wiping the stats causes a bad battery read. A few reboots should get you back on track. If that doesn't work, try a full battery drain then a full charge. Let us know.
Will try that, even tho I kinda did already. I'm hoping with a few battery cycles the problem goes away.. What Im hoping is I don't need to bump charge now every time like I did when I had my inc

I doubt you lost anything. It would be like Spinal Tap having an amp which only went to 9.
I only had to wipe when my battery wasn't decreasing in percentage. After I wiped, it started decreasing like it should. I would think any fast reduction in percentage would be a bad battery.
Are there any proven facts out there that it is really ever necessary to wipe them? It's not like it actually improves battery life am I correct?
as far as wiping battery stats goes.
i have only used it when reconditioning a battery.
ie if you start noticing bad (read: worse that you have been getting) battery life after flashing a new rom or kernel. or just after a time using a standard rom.
what i do is
1 turn the phone off.
2 charge it on AC until it goes green and for an hour afterward.
3 unplug it and wait 30 seconds.
4 plug it back in and repeat step 3 until the light goes from red to green within 20 or so seconds. (this is called bump charging)
5 boot into CWR and wipe battery stats. and let it burn all the way down until it wont even turn on (flashing orange led)
6 charge to full and enjoy your maybe improved battery life.
when wiping battery stats, do i have to do it a few times or no? i wiped battery stats at full and drained battery until it turned off twice.. once wiping the stats with CWR and once, and after a cycle, with the 'battery calibrate' app (made by someone here on xda i believe)..
seems to be working okay i guess, but lets say i have 94%, i reset my phone and it comes back with only 84%.. it appears it's still reading my battery wrong by around 10%. is this normal?
It doesn't happen at every reset, looks like just the first one of the day. I guess I can charge to full, reboot, and charge to full again as a workaround.

i meant to ask this before but I forgot, can anyone try to do that and let me know if it happens to them too or if its just me
Charge with phone on until full then turn it off and charge.. about how long does it stay amber?

Not battery life.
Today i noticed my battery meter has been sticking, any way to fix that? It'll drop 20% upon reboot.
Today i noticed that my battery would spike up from 95% to 100% while charging and not go anywhere in between,. Is that normal? Battery calibration app kept going off early, and then as soon as it hit 100% i unplugged it without calibrating it, and it dropped to 99%. Happened twice in five minutes.
Also, instead of using clockwork recovery, i use Battery Calibration app to wipe my batt stats.
What mV should i be on?
One last thing, how do you bump charge? And is it really that unsafe?

I noticed this yesterday, I had my phone plugged in and it was at 94-95% and 2 minutes later it was at 100%.
To bump charge, once your phone is at 100%, unplug your phone power it down then replug it in. Once it shows the green LED meaning 100% charged boot your phone up and keep it plugged in. Might go back to being orange saying its not 100% yet so let it get to 100%. Unplug it and replug it back in a couple times until every time you plug it in it shows green for 100%.
I would think that it would be bad for the battery if you do this every day, but I can't give a definite answer for that. I use Battery Calibration to do that too, but between today and yesterday after I flashed over the new CDMA/LTE radio leak from the Radio thread my battery life hasn't been great. Considering going back to the stock radio.
I've noticed similar things on my bolt and even my dinc. To counteract this, I stopped looking at the battery % and got battery left instead. This app tells you how much longer your battery will last in hours rather than %. I no longer freak out about my battery life, %, or what others are getting; I've never been happier.

Sounds like a good idea especially for me lol. I noticed this morning that my phone was 56%, down from 74%. 18% drain over the time span of like 6-7 hours or so while I was sleeping. Not sure how good or bad that is, but for me it was just like wow.
You're being anal. Don't worry about it. Your phone is working fine. The battery level will appear to jump around a bit, especially when going on/off charger, or rebooting. Search around if you feel a need to know why.
Hmm...well, this is the second time that this has happened in the 2.5 weeks that I've owned this phone. I'm currently running unNamed ROM 1.2.0 and noticed that my battery is draining quicker than usual (8%-10% drain per hour on IDLE).
Usually, my battery drain is between 1% - 2% per hour on unNamed. What I've noticed in both the instances where my battery drains rapidly is that I end up seeing 'Core Apps' (white envelope with android icon in the middle) under the Battery Usage. From what I can recall about this icon, it's the icon for the launcher. CPUSpy shows my phone at 78% deep sleep (the phone's usually around 93% - 95% deep sleep when in idle).
The first time this happened, I was away from home on business for 1 night and ended up having to power my phone off when it got down to 11%. Got home later that day and recharged my battery while the phone was off and after the phone was 100% charged, it lasted 38 hours with 7% left before I powered off and recharged. Again, the battery with light usage lasted 30 hours with 30% left.
Today, after charging (while off - seems to charge better this way) I was surprised to see that my battery was draining at ~10% per hour and I saw that 'Core Apps' was listed under Battery Usage again.
Fortunately, I am not away on business this time (yeah, my spare charger is on the way) so I can recharge teh phone at home. Is the only way to "reset" the phone's battery usage history by pulling the battery or charging the phone?
Hopefully, one of the devs can answer or provide a fix/workaround for the 'Core Apps' drain? (BTW, I leave my WiFi on all the time and my phone still lasts anywhere between 28 hours to 40 hours...just wondering why I have these sporadic glitches when the battery doesn't seem to last long.)
From my experience... this will be very hard to fix. Usually appear ramdomly, and disappear randomly.

Yeah...the 1st time it happened, I was wondering "WTF is 'Core Apps'?"
Now that I've seen this the 2nd time, I'm stumped by it since you're right...it doesn't happen often and doesn't seem to be reproducible by any consistent method.
Hard to do a battery pull with this Neo Hybrid case (case is a PITA to remove) and I don't have my 2ndary charger yet...
Rebooting the phone does nothing since the battery history remains and even powering off for an hour and then powering the phone back on still doesn't clear out the battery history so the drain continues!
Oh well...it is what it is then I guess...I was hoping that someone smarter than I could find a way to cure this. (BetterBatteryStats doesn't show this as a wakelock (partial or full)...CPUSpy just that my deep sleep state is in the mid to upper 70% which isn't the norm.
Oh well, hopefully, this doesn't happen too often.

But a few have reported their phone doesn't behave right in reporting battery percentages after wiping battery stats.
Doesn't mean you can't. But no one has proven it helps.

I haven't had any issues that can't be directly linked to something else (like random reboots).
If all you want to do is reset your battery useage screen to zero it definitely does that. The point isn't to help anything, just to reset the screen to zero without having to wait for the phone to charge all the way.
In that case not a bad idea if you see it show up. If it's as bad of a battery drainer as it seems and still running, it should show up again pretty quick after you clear battery stats.
It'd be useful in reading the logs to know that at a certain time it was for sure running.

Dunno, it's just odd...recharged my phone last night and now I'm back to 1%-2% battery drain on idle and the phone's going back into deep sleep at 93% and I haven't touched any of my settings. I just let the phone dip to 19% and powered off and put it on the charger for ~4 hours (I know, I could've pulled it sooner since it wasn't at 0% but honestly, I forgot.)
It's just the weirdest thing...whenever Core Apps appears as the envelope w/Android icon it seems to be persistent and stays in the battery usage. However, there have been times when the Core Apps appears as teh same icon as 'Contacts' and will disappear on it's own after a while. <-- This seems to be okay as the battery drain remains minimal.
I'll have to check out Entropy's battery drain thread later to see if I can gain any insights. (Haven't ever flashed any of Entropy's kernels as standalones -- I've just been flashing unNamed ROM so I know the kernels are stable builds and not the experimentals.)
I have had my White AT&T Note for about a week. It is running Saurom RCV with the HoloNote kernel OCed to 1782mHz. I am having a really weird battery issue where it will drain to about 5% in a couple of hours regardless of what I am doing to it, then that 5% will last the rest of the day but the phone, thinking the battery is about to die, wont let me do anything (ie. listen to music or take a picture). Then, yesterday it started not charging all the way, it will stop at about 94% and then the notification that its fully charged will come up. No matter what I do it will not go past 94%. Any ideas? Thanks in advance!
have you try to recalibrate your battery stats through CWM?
try that first........charge your battery to full......clear stats....drain all the battery...then recharge to full......that should help you with ur problem
First take the battery out and make sure you don't see anything on the contacts (phone or battery). Then leave the phone on until it dies on its own - easiest if you use something that will keep the screen on. Then charge overnight, unplug, replug and let it charge again until it stops. Turn it on, go through your day and report back.
I have tired both of your suggestions. I left it streaming a movie from Netflix and it took two movies at full brightness (or as full as it would let me) to kill off the last 5%. I apologize as I should have specified that I am posting on here having already tried conventional calibration techniques. Also, the stopping at 94% only started AFTER I used CWM to reset the battery stats.

I've never used CWM. Have you tried using it again?
I have noticed another "quirk", it seems that when my phone is sleeping for a long period of time, more than an hour, it will usually display more percentage than when I set it down. For instance I decided not to charge it last night as I was hoping it would die in the night however when I got up this morning it read 51% whereas it was at 26% when I left it. I am starting to think that there is something wrong with the hardware. Opinions?

I didn't nitice this till last Tuesday. I forgot to charge my note the night before, and when I woke up I had 19% left. Around 10am I received a notification that my battery is critically low. I wasn't going home till 12, and I was texting heavily for 2 hours through whatsapp on 4g network, and nothing, the phone didn't turn off. I got home and plugged it in while it was still on. The only thing the phone did was turn down the brightness completely, im not sure if that 's the reason for the extra 2 hours, but that seems too much. Before i plugged in the phone it had 23 hours on battery with 4 hours 44 mins screen on time.

Has anybody experienced any of these issues on a stock note? Also, I tend to agree, if Samsung had really figured out a way to make the end of the battery last that long we probably wouldn't be having this issue.

I exchanged my Note for a replacement at the store and that has made a world of difference. It would seem that my suspensions about my hardware were correct. If you are having the same issues I recommend a replacement.
Thanks!
I charged my phone during the night to 100% and used it for a bit this morning. I went to the beach for the day, and left my phone at home. Upon returning (roughly 5 hours later) my screen was stuck on the ATT splash.
I looked at my battery usage to see if anything strange had happened, and I was greeted with the attached image.
I am currently running stock ICS 4.0.3 from ATT. Rooted with Kernal version 3.0.35-Siyah-v3.4.2. I do have a lot of widgets on my home screen, but I have had this same setup for more than 2 weeks and nothing like this has ever happened before.
Pleas let me know if you need any more details. Any and all help is appreciated.

Download batery calibration app from market, charge until you get 4200mv, disconnect charge, calibrate then after succesful calibrate restart phone then dont shutdown until you get force shutdown.
If you cant get 4200mv, wait to the highest value then calibrate
Anyway your signals are very low, it will be drain battery rly fast, try make them highet and keep wifi shutdown

Why does low signal strength quickly discharge the battery? Also does this explain for the gaps in the battery info or is it something else?
Our phones do not require battery calibration. Have you installed betterbatterystats, and watchdog? If not, install them and see if it happens again. I can tell you that it's not the official update that's the problem, as I had it installed for a few days. Almost gotta be a rogue app. You could also try switching kernels just to see if it helps.

Thanks but again, whats going on? If I have been using the same setup for more than 2 weeks, shouldn't an occurrence like this have already happened?
I had a similar incident today running stock 4.0.3. no root. Phone went black. Once I noticed it, I restarted it which it didn't want to do at first. Went to the battery stats and it looks similar to yours. Battery level showed about a 50% drop. Never had that happen before.
Well I am going to try the first suggestion and see if that helps. I'll report back later.
It seemed that the first option worked pretty well. I let my phone sit for 8hrs today, and the battery only discharged to 87%.

Probably kuz it didn't reboot. It looks like your phone rebooted quite a few times for whatever reason, back to back, possibly got stuck in some boot loops too. Id call it a fluke unless it happens again.
And there is no "calibrating" our battery. If you reboot at lower capacities it'll come back substantially lower and then correct itself slowly over time. Its just how our meter works (voltage reading vs mah counter)
