Hi everybody,
I've read somewhere that it's preferable that the battery be fully charged before to flash. Does it the job if I flash with the charger connected or do I have to wait until it's fully charged before to flash?
Thx.

its advisable that the battery is beforehand >60%...
I have flashed numerous times while on charge, tho I would imagine its preferable to take it off charge, what you do need is at least 3800mV in the battery

does not make a difference if its on or off charge, the battery been full when flashing is just for minimizing risk of bricking your device,if your device goes dead during flashing im afraid its game over,
hit t****s
I asked this question because I have read that battery statistics get wrong when the device is not fully charged before to flash.

Battery stats always get thrown a bit and being fully charged does help avoids this, but a few full charge cycles is all you need to reset/recalibrate

i flash numberous of time when my battery > 30%
no problem till now.
but it is advise to flash with full battery for your phone safely.
Thank you for your answer.

flashing a rom the battery need to be full so you don't need to recalibrate your battery after the flash, but if you need only to flash kernel it no need to be full.

it is just an safety net , when your batt is low , you are flashing an kernel , wile flashing the kernel the batt dies out , you can get in sirius truble.
that cannot happen when your batt is full , so just an safety net

So yesterday I calibrated my battery and was suprised it actually worked. But today I flashed a new rom (for like the 6th time this week, I think I have a problem) Should I calibrate again?

I /think/ it's only when you flash a rom without a fully charged battery.

Well if you have tons of time I don't see why not. Most of the time, I feel that it is not necessary to calibrate the battery. I only do it when there is a severe battery drain.

+1 to this. Please ensure u flash a ROM after u charge the battery to 100%.
I've been looking but have yet to find directions on how to calibrate a battery. Can some one please tell me the ways to do this?

Charge the phone till 100% while it is turned on, disconnect the cable.
Turn it off and charge it till it's 100%, disconnect cable.
Turn it on and off, charge till it's 100% and disconnect the cable.
Now, delete battery stats using CWM or run the following command using ADB or Terminal Emulator:
Code:
su
rm /data/system/batterystats.bin
Sorry but what is cwm?

Can I flash a new ROM with 60 percent battery? I see where most ROM'S recommend flashing with a full battery. Does this affect anything like how much charge the phone thinks the battery has? Or are there other reasons to flash with a full battery?

It doesn't matter. I flashed at 5% once. The only thing you have to do is recalibrate your battery after.

That would be a big problem
I tend to always flash at 100%. Just to avoid any issues. But you can flash at 60% if you really wanted to. Just do a calibration
Do it with full battery . Calibrating takes ages

If you are using odin, by definition the phone is plugged in to a USB power source. I suspect you couldn't drain the battery in that circumstance - maybe if you were plugged in, playing a video while serving up Mobile AP. But not when the screen is doing nothing but saying it's in download mode.
I have flashed through cwm with under 50%

That's assuming every one uses odin
I just clear data and cache and flash the new rom. But I charge up to 100% so the battery reads fine.

Yeah thats why I said "somehow". I thought about your point while posting though and it makes plenty of sense and im pretty sure you can charge a phone no matter what state it is in (soft brick, hard brick, waterlogged ha)
Sent from my SAMSUNG-SGH-I897 using XDA App
Yea
I've flashed in the range of 50 - 100%, never had a problem
like others said you just have to recalibrate your battery after.
I probably wouldn't go less than 50% though just to be safe.
It would probably be best to flash on a full battery, but I don't think its necessary. Just recalibrate and wipe battery stats and you should be fine.
Yes you can. May need to calibrate

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.

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.
Sent from my DROID3 using XDA App
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%
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

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

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

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.
