Hey all, first off I want to thank everyone for developing cyanogenmod and phiremod and everyone else involved it has made my nook marvelous. Everything has been running really great but recently I started noticing that when I charge the nook the cable goes green and battery reads 4200 for voltage both indicating a full charge but all my battery readers read 96/97%. Additionally my nook dies prematurely around 20% and won't turn on unless plugged in. I'm running phiremod 6.3 and followed directions for 100% battery during flash and using recalibration app. Anything I am missing? I am not super concerned since I seem to be getting 8 hours of battery life hut still just bugs me, anyone else having a similar issue?

Hello all
So, I'm building some apps for my HD2 and so I am plugging the phone into the compy quite a bit. I've always thought that the "Battery Memory" issue of not charging the battery to 100% and only charging the battery when it was low was an old wives tail (a myth) but now I'm noticing that 6:00 PM rolls around and I have like 15% batt?! I have flash ROMs and Radios since then, but still... this seems pretty dramatic.
Have I messed up my battery by doing this or am I just seeing things?
p.s. I have gone back to 2.12 Radio, and I think that radio had the best battery life for me. Hopefully this fixes things....
p.s.s. Yes, I know I can not charge when hooked the computer. I just figured it wouldn't hurt anything if I charged.
After successfully booting into android for the first time my battery life in android skyrocketed down, but that didn't really bother me.
The real problem is that even in WINMO my battery life is less than half what it used to be, and even after a night (8 hours) of charging (In a wall socket, not USB) its not at 100%
this has me very worried, any ideas? thanks in advance!
did you read anything before you started this thread...........
yes, i did. everyone is having a problem when they charge in android it gets to 90% then they switch to winmo and within minutes it picks back up to 100%.
this is not the case for me, my battery does not jump back up, it drains quickly even in winmo, and when it gets low its not just reading it improperly it just dies, so no this is not the same problem
did you know there are fixes .......and that your problem is not new at all....i am sorry to say that this is a know problem and you would want to ask in the thread of what build you are using and if you really wanted help you would post what build your using and what kernal , but no one can help you at all when you simply state you have battery issues
drain your battery in winmo till it dies, so the battery resets, then charge the battery again till full, it should be allright again.
thank you dipdap i will try that

I strongly advise you NOT to do so. Draining a Lithium-Ion battery entirely is detrimental to its overall life/capacity. So instead of ruining your battery (or going a step towards ruining it), simply turn off your phone, charge it until you get the green LED, boot back to WinMo and it should be alright. If it isn't, look for another way, but completely draining your battery should not be the method of choice.
nobody said to drain it copletely, just till winmo dies, which should be fine. I do this once every couple of months by accident, and have never had a problem. I agree that you should not drain the battery completely though, so, make sure as soon as winmo dies, plug in to a charger.
what rom are you running? I am using shubcraft 1.5 and mine charges to 99% And I can get a full day out of my battery with pretty decent use.
Are you using setcpu cause that could have a major impact also do you have wifi,gps or bt on. I know gps has been known to cause some major drain while in sleep mode.
There is also a thread where people are trying to find solutions to the high amount of drain in the development forum.
We use current widget to create a log and monitor Our drain. You should be seeing less than 10ma while sleep I usually see between 3-7ma while sleep
Funny how when you are watching your battery it drains faster. When you are watching the clock time goes slower.

You can look at this thread

It was very helpful for me to identify how much current is being used while in sleep mode and active.
Download "current widget" from market and monitor your current supply for 30 minutes during your phone's screen is off.
Yeah with the screen off you cant see any thing but thankfully the log will be written for the current widget every min.
If your current comes out to be bellow 10ma during this time then you are doing good and should last you one day of usage else you need to pinpoint what is drinking all the juice even while your phone sleeps
Read the thread ALL OF IT, it will help you understand better.
Cheers.
alright thanks for all the help guys, the battery drain actually worked although i felt strange doing it, but still my android life isn't so great, i would love for it to work completely though because the only wquivalent option on my carrier is the Captivate (Galaxy S) and that thing is ugly compared to the HD2
such problem
I have such problem with battery drain under WM, after i run and quit android, but i found a solution, just pull out your battery few times next just recharge it and it will be OK .
Had my wildfire for a few months now, finally decided to root and flash a ROM after my service provider failed to roll out froyo. It's all been pretty simple and I've had no real difficulties, but my battery is now draining at a stupid rate.
I mean, with all the typical battery draining applications/services off it is still draining faster than pre-flash with all of them on. Literally like 1% a minute while hardly doing anything.
I've not bothered to overclock, even went so far as to underclock processor, still to no avail.
I've tried a few ROMs now and they're all the same, currently running 6.1.0 wildpuzzle. It doesn't help that I have a slow charger (original broke), this normally would do a full charge in around 10 hours so I'd leave it overnight. But now the battery drains nearly as quick as it can charge.... I've not even had it at 100% power since upgrading to Froyo.
Any ideas how to fix this? Obvious suggestions will be to try a fast charger (will do tomorrow round a friends) but I cant see this making a difference other than making it possible to fully charge and waste again in an hour after unplugging.
Battery life was typically 8-48 hours previously.
Ok, so I've finally got the battery to charger to full. However, the voltage reading is given as 4V, whereas is was previously around 4.2. Battery isn't fully charged. WAT DO? :\

Hello! I'm having serious problems with my battery. Since I installed CM10 my battery just goes from 80 to about 60 or 50%, then it drops again from 40 to 20%. Already tried to calibrate with battery calibration app, or this methods, done full wipe (did the process from the beggining, back to Cm7 and no results at all!
Pictures attached.
Please, pleaase help! I'm selling my defy, and do not want to sell it with this issue.
PS: Original battery

After checking the ownership in root explorer or simular apps, recharge to 100% and let it sit for a couple of hours. Do that again after discharging it.
You will probably be selling a worn battery anyhow, but then maybe with a calibration so the percentages work. This is mostly due to changing with a fast-charger (not the stock one) or charging it not often enough. If you have the habit to let it go to 0%, then it is worn in less then a year to a degree that it last for a couple of hours less then in the beginning.
New battery is the only way, I got an anker one off amazon for £5 and have great battery life on cm10. The
above method or a change of ROM may help but the only real cure for me was a new battery

Hey guys, How you all doing ?
First of all, I recently got in hands a Nexus 6p! Bought It used (8 months of use), and its perfect, everything os ok.
Then, I rooted It and now i'm using the Android O ROM, with franco kernel.
But, I've been noticed that the battery sometimes drains 2%-3% too quickly. And yesterday my phone shutdown at 18%!
I was experiencing the 2-3% drain on 7.1.2, but not the shutdown.
I dont get that bad SOT, like 3h-4:30 is still a thing for me.
What do you guys think ? Is It bad battery or software related problem ?
Should I consider doing this trick and go back to Android N ? https://www.google.com.br/amp/s/for...-6p/help/nougat-battery-bug-fix-t3559250/amp/
Here is one print from my screen on time and accubattery.

First of all, going "back" to anything is not going to help you. Android 8.0 is not the issue, it may be a degraded battery, especially if you are having early shutdowns. Please open the Health page (Saúde) and post it. That is where you will find your estimated battery capacity relative to a new battery. You should have a few full charges before this percentage stabilizes. Try draining it as low as you can go (or when it shuts off), and then let the phone charge fully until Accubattery tells you your phone is fully charged NOT the phone reporting 100%. It's common for the phone to continue charging 45-60 minutes beyond the phone reporting 100% and you need to keep it on the charger until completely full to get an accurate capacity estimate. Hope this helps. Boa sorte!
Okay. I went back to 7.1.2, early shutdowns got resolved, but the 2℅ drain not.
I followed all the steps of the guide I posted, changed governator, etc..
It have seen to got a little better. Will report back after a few days of usage with accubattery health status.
Thanks!
