Battery charges as fast as it drains??

Im on serendipity 5.10 and I flashed speedmod k13b using odin and k13c using sgs kernel flasher. I notice battery drains 1% every 10 min and charges up at the same rate. This did not happen when I originally flashed the first time (serene 5.10).

I will actually test it a couple days then I'll see.

6% an hour does not sound to bad for me ^^ but i highly doubt that it takes over 10hours to charge your phone

How are you gets getting such high battery life?

I went back to speedmod k13a cuz it seems to have better battery. From what I read, the kernel needs time to adjust after some flashes so let it charge/drain a couple days and it'll be better. I did that and i seem to have better battery.
Edit: not significant though. I'll test it more.

Is this idle drain?

all depends on your use and rom. I get about 1-2% drain per hour idle using whats in my sig along with juiceDefender to turn off data (cell and wifi) when not in use.

Copying battery stats file?

Would it work to just copy the battery stats file to another rom so u don't have to re calibrate everytime u install one or would that be a bad idea

You don't need to calibrate, just charge it full. Battery stats are automatically wiped when you unplug with a full charge.

Well the new 3500 milliamp battery I got says to fully discharge and charge 4-5 times to get the most out of ur battery. Or is that just for when u first get it

Just when you first get it. Its a "break in" for batteries.

Although I believe that its good to do a full discharge and charge every so often.

Alright that's what I thought. Although while discharging my phone froze up and rebooted so I think ill have to recalibrate again lol

It shouldn't affect battery. I've tested it myself, battery life before and after calibration is no different. This calibration myth was debunked by a google framework engineer.
Sent from my XT860 using xda premium

ya I read a short thing on that. Kinda odd though. Seems like sometimes u could get a worse battery life some days compared to others. But it also seems like a good idea since u don't have to calibrate every time u do something.

The calibration has nothing to do with the battery life, it just gives a more "exact" reading of the battery level.. I miscalibrated my battery once, and it was at 1% for about 3 hours, then finally died..

Ya that happened to me once. Now I just make a point of being able to fully charge anytime I flash a rom.
Sent from my XT860 using xda premium

I have now been convinced that there is no reason to calibrate your battery at anytime. Google engineer pretty much put it to rest and since then I have flashed repeatedly and all that changes is the ROM , sometimes battery is bad and other times its great. CM9 is best so far. Until we get new kernals our battery won't ever be great.

Ya reading through the comments it seems batterystats.bin has nothing to do with the displayed battery level, but rather just what is using the battery. The displayed battery level comes from kernel level

Same, although not for 3 hours but 15min heavy load (720p mkv). Which normally kills 10% battery.
After calibrate it never happened again and died right after 1%

Battery

I some up this morning and saw my battery was at 88%, it has bin on charge all night how can I fox this so it charges to 100%?

"some up"? Ok... go to CWM->Advanced->Wipe Battery Stats ... if doesn't work, do a full wipe or reflash ROM, you are using...

Woke* auto correct lol, and o do this after every ROM flash and this wouldn't affect that anyway, its not done it before, only to 98% or something but I read that it does this it will reach 100% the stop charging to preserve the battery, but dropping to 88% is a bit extreme I think I'm losing like an hour of battery life

This is a calibration problem caused exactly by you wiping your battery stats, you need to leave them alone and after each flash do a full empty to full charge cycle so the stats can provide proper calibration statistics, I have never wiped battery stats in 2 years of owning my phone

I always do this after a wipe, wait till fully charged>wipe stats>discharge fully>recharge fully
Sent from my GT-I9000 running remICS-UX using XDA premium

Ok, I know the point you are making but I personally think it does more harm than good.... Does it drop straight down the moment you remove the charger?

I don't know if it might be a battery problem, or if the CM9 Nightly build I'm currently on holds a charge really well, but sometimes I charge my phone up to 100%, then after about 30 minutes of continuous, non-stop usage, the battery is still at 99%.
Is this odd behaviour or is it normal?

No it only charges to 88% unless I remove charger then plug it back in again then it will charge to 100%, I think its because the phone charges to 100% then drains then charges, but I think its failing to start charging once it drops to a certain limit (say 10%) so normally it would charge to 100% drop to 90% then charge to 100% so it doesn't damage the battery, but as I said I think its failing to start charging again so it just keeps falling... I need a fix for this? And yes it is a cm9 base

I've always been wondering: is it possible to "damage" the battery or lose some of it's juice by doing wipe battery stats to many times?

Battery drain after restarting note on 4.0.4

My battery has been sluggish right after updating 4.0.4. Right after restarting my device, i left only 20% of battery instead of 90% before restarting. Im getting sick n tired of samsung. Thers always a problem after software update. Im wondering wether they ever tested their software before releasing it to consumer. LOUSY

Calibrate your battery.
Let it empty untill blackout. Take out battery for 2 min then put it back again, and charge it to full, do not push the on button while charging.

My suggestion is to install and SPYCPU podesiš processor clock so you would not spend the battery more than they need. We also have a large selection governo, naćićeš best balance of performance and battery life.

Thanks jonpaslim! i will try to do that and will update the results

The total of 1 week I was on both OS builds I had these issues that I identified to be the battery:
Facebook
GPSD
and then not going into deep sleep (the phone gets warm)
Badass Battery (now another name, but you can still search Badass battery) and BBS (Better Battery Stats) helped me.

Thanks zkye.
So far i hv been using pretty alot of apps. Been using carat,netqin and cpu spy. Well the batt is still i would say average.. Im wondering how to read this thing on cpu spy. Especially the deep sleep graph. Is it sufficient? Or am i doing the wrong thing or what?

You can check version in settings, then about phone in bottom Guess you are on stock. Be carefull wiping, factory resetting and deleting large files as kernel can trigger a bug in emmc chip, corrupting partitions.
good you started analysing root causes. Always best case.
now if you dont care for warrantee you can follow directions from this post http://forum.xda-developers.com/showthread.php?p=29139461 to get back to starting point of install. Or to install the awesome speedmod kernel.
Alteratively you can add apps one by one and together with battery usage analysed you can fin culprits. With tools like betterbatterystats, cpu spy and badassbattery monitor

did you try re-calibrating your battery?

Hi xfox,
Done with calibrating as in let it empty, take out the batt for a while then turn it on again. It seems okay for now. Is there any other way instead? Im sorry for asking this stupid question again and again. And thank to all of ya for replying my so called newby question. Lol.

Thanks baz,
How i wish i could use those speedmod kernel and so on. Well im quite afraid to root it cuz im not too sure that im gonna use this phone for a long time. As the phone value will decrease if i void the warranty. But thx for replying my post tho. As for now im still monitoring my batt behaviour.

Galaxy Note problem
When I got my Galaxy Note, the battery used to last for 10 hrs on GB. After upgrading to ICS, that time dropped to 8 hrs. And after ICS updates, it went down to less than 4 hrs since it was discharging much fatser than charging, and it was the same whether I used the original power charger or direct USB cable.
The original charger is an adapter + USB cable.
Everything went fine when i changed the USB and used the one originally used to charge the Sony 3D glasses.
Now it's charging normally and the discharge rate is around 8% /hr with WIFI and mobile data ON.
Hope it will work for you.

[Q] hot phone, not charging

Hey guys need some advice here. My one just recently hit 120F the other day and now that's a norm when charging. (screen off charging) Also, it will not charge even overnight, after about 6 hours the battery went from ~14% to 64% and the led was blinking red, battery indicator did not show that it was charging.
What can I do on my end? I know I'll probably have to get it replaced but I just wanted to know if there's anything else that will fix it.
Thank you

Try charging with the phone powered off. I know this might help cuz you need your phone on but it's the only option. After that send it back.
Sent from my SGH-T999 using xda app-developers app

Blinking red while charging means the phone is too hot to charge. Wait until it cools down and try again.
You can also try a "battery pull" by holding down the power button while the phone is on until the capacitive button lights start blinking and keep holding it until it turns off. Temp sensor might be stuck.

Yeah ill try doing it powered off. It's weird cuz that's how I always charge it, but hey its hitting 100F ambient temp here so maybe that's it. My phone also gets super hot when watching a video and can drain a full battery in about 1:30 hours

Might try a battery stats app and see if something is running away on you. I occasionally use opera browser and found it would kill my battery really fast with the screen off if I didn't actually exit out of it - can't ever leave it in the background. Maybe you have something similar...
