yesterday after flashing nero 5 i wanted to recondition, so while sleeping at night i charged my phone to 100, and now during the day time im trying to waste the battery, but during that i got caught up on adb and connected my charger, and left it there, now its back at 83% battery, does this mess up the reconditioning process? or do i have charge back to 100, then do it all over?
anyone? please lol

what you should do is drain it all the way untill you cant turn it on anymore and leave it chargin all night turned off, and when you wake up turn it on and let it charge untill its full again, then boot into recovery and wipe batt statt , and you should be good to go mine last about 20 hours after i did that

I did just about the same with mine, minus the chargin all night turned off, and I am getting about 20-24 hours with mine, which is more than I need as I plug it in every night

me to im near a power source or computer all the time so
What you should do is keep letting it drain until 1% or so. I don't think you need to let it die completely. Charge to 100%. Boot into recovery and clear battery stats with the charger still plugged in. This is the important part. Then drain the battery and charge to full. Then you should be good to go.
question, after draining to about 1%, does the phone have to be off? and can i use the phone just a bit while its charging?

The general consensus is that when you condition you should charge the phone while it's off. I don't know enough about battery chemistry to tell you why. Just do it to be safe
Battery "recondition", actually does not "recondition" the battery, it is a trick just to get more accuarte readings (that's the only reason you reset STATS)
The battery may not charge up to 100% and will never do, just following this procedure. It will just say it is @ 100% when you actually are @ 85 or 87, that's why the sudden "jump" you see.
Best way to try to get better readings is charging the battery till it says 100%, unplug it and plug it again a couple of times until it fully charges and follow the same procedure.
Once yo did this a few times, turn off phone, reboot in CWM (with the phone never unpluged) and clear battery stats. turn off phone and unplug,,,,
You will got at least more accurate readings

Android Police did a piece on plugging and unplugging your phone to get up to 100% (it's called bump charging, see below). They recommended that you NOT do it because it doesn't get you much additional juice and you wear your battery out faster. Normally I just charge my battery up to 100% (no drain), wipe the battery stats, unplug and go until it dies. I use it while it's plugged in and still get a full day easily out of my phone.

I hate to be the bearer of bad news. You can not condition a Lithium-Ion battery. All you are doing is wearing it out prematurely by deep cycling. Every time you do this you destroy your over all battery life a little.
I have posted about this here in several thread, and I am getting a little tired of having to tell people NOT to do this because they don't search for themselves. Do a search on the forums for deep cycle li-ion and see for yourself.
If you want to know the technical reasons why, Google is your friend.
so we just deal with what is perceived as faster battery depletion?
Im asking because As i have posted on another threat I am a complete freak about my battery life.
Basically yes, I have 3 batteries to go around all day, although I us the car charger, if for any reason one day I take the train to the city, I will eat up 2 and a half batteries in a day.......
I had 3 batterys for my hd2 I need to get 2 new batteries for my vibrant. I guess im just tripping because I tried and over clock kernal and it seems like its dying faster while the screen is off

Yea, just chill. It is all in your head. From ROM to ROM, usage pattern to usage pattern, and app version to app version - there are just too many variables to worry about. Just use your phone, charge it when it needs it, and relax.
Your phone's battery is going to get less life as it ages. There is nothing you can do about that. Also, it will likely only get 2-3 years before it needs replacement. If it gets less than 2 years it is because you have been "conditioning" it. which ages it prematurely and also causes how long it lasts between charges to shorten as well.
Li-ion does not have a memory, so conditioning is an inherently false concept. Recalibrating the devices ability to read the battery is a different story, but it should only be done if it really needs it (like it thinks it is at 1% when it is at 20%), and it should never be done more frequently than a minimum of 30 charge cycles or if you charge it once a day when you go to bed no more than once a month. Less frequent is better.
So sorry, you need to find something else to obsess about. Might I suggest getting Team Whiskey to make BlackFroyo the default theme, use the 5 bar signal meter, the larger numbers on the battery, and the hacked camera the used the power button to take pictures. That would save all of us some time.

Nice link - try reading the stuff by the engineers that work with batteries for a living now instead. You do know eHow is just a site where any idiot that thinks they know something can post, right? Are you going to reference wikipedia next?
BTW when you recalibrated your battery and got 6 more hours, did you do anything else that might have explained it? You know like flash a new effing ROM? That might possible change a few things to do with your power usage.

it was a joke
and no, i flashed Nero 4.1, and then used it for a week thinking the phone would adjust to the battery and new rom, it didn't.
then i thought i'd just take a chance and recondition my battery, it was my first time, and it worked out great.
and trust me i'm a heavy user.
roughly 300-400 texts per day.
20-40 phone calls
music about 5 hours per day
and i play soem games, but thats understandable because playing dungeon defenders uses like 30% battery per hour bcz of the high graphics and such.
a bunch of app downloading.
If I keep my phone on charging even after its on 100%, it starts rolling back. As in from 100 to 99 then 98, even if its pluggen in.
Don't know what kind of a problem this is, hardware or software.
Or there's some issue with the battery.
Please help.

Maybe You have some program that syncs something all the time. Did You try to turn off data and wifi. You can always check it if the reason is the hardware or Software. Just make a backup of Your whole ROM, delete the data and leave the phone over night. I hope it is only software problem.
EDIT: Does Your battery go hot while charging? Oh, and try to wipe battery stats

The x10 charges the battery to full then if still plugged in it will stop charging until batt drains to set level ,then will charge to full again and over and over all night. X10 wont over charge batt when left plugged in. Kernel/bootloader handle this. There is an app current widget that can log charge levels.

EDIT: the best tip I usr for battery life is, let batt runout until phone shuts off, then pull batt, then plug in charger, then replace batt into phone, then phone will boot, enter xrecovery on first boot and wipe batt stats. After wipe while still in xrec pull batt then unplug. Now plug in phone then insert batt. Phone should boot in charge mode( big batt icon only on screen) dont start phone untill light green for 1-2 hours to get full charge . I do this about once a month, when phone starts to shut off around 15%

As mentioned above as well, this is normal. After charging to 100%, the phone stops battery charging, and will activate charging again only when battery falls a bit (say 97%). Also, battery heating while on charging (and also when using the phone continuously while playing a game) is normal. Relax.. your phone is fine
@ToledoJab
I am having the same issue with battery... phone switching off at 15%, even at 22-23%, when playing a game or something. But switching it back on, and leaving it idle, phone might run for another 2 hours. So it is the extra load while running a game that the phone cant take any longer (i remember getting the 15%,10% and 5% reminders earlier while playing games)...? Does the battery calibrate method actually help in your case? does it go all the way down to 0% or 1% before shutting down.. ?
I just did this after posting that. And yes my phone reported warnings @ 25% 15 10 5 and then shutdown @ 1%.
This way is like reconditioning an old rechargeable ni-cad batt.
All this does is completey drain batt then, with least amount of drainage (phone on, apps& radios running) allows battery to full charge.
There is also a way called recalibrate battery. But this way over charges the batt.
EDIT: I think the phone load will effect reported batt left. I think batt gage use average loads to estimate remaining power. Meaning games, full brightness of LCD, radios -3g -GPS -WiFi -Bluetooth will use more than avg power
edit 2: I found this thread also has some very good points and links. after reading this i will not intentionally take my batt to 0%. I hit 0% about 1-2 times a month on accident as it is. i will just make sure when i do go 0% to wipe stats (dont know if it helps or not) then preform a long (overnight) full charge with phone off.

I tried searching this in a number of places. I couldn't find what I was looking for, although it didn't help I had trouble using the right words to search for it with, but here goes.
I'm running CleanROM Reborn 1.1, I love it! Other info is also in my signature. Once I turned on the percentage number for my battery level, I really started to notice this.
The number will stay at a number for awhile sometimes, even when I use it, then other times it will jump several points within a minute. It doesn't drain consistently. Anyone have any insight or suggestions? It's more annoying than anything else. My battery life is alright.
I would've tried wiping battery stats, but I hear that doesn't really do anything.
Thanks.
download Battery Calibration from the Google Play Store, then charge your phone to %100. open the Battery Calibration app and calibrate it. There is also instructions inside the App if my instructions are unclear
Im going to try this but for some reason mine only go to about 96%. Never 100% lately so I am not sure if I should do it then or just leave it charged until it is 100% and hope it gets there.

Not to hijack the thread, but the phone is designed to fully charge and then discharge to 95% and then charge to 100% again, rinse, and repeat. This is to keep the battery from becoming destroyed by overcharging. Maybe that's what you are seeing, Bambino.

I've noticed this too on Ics leak roms. It sips power with screen off, then drains quickly when on sometimes and hardly at all other times. Mine just sat at 82% for the past 20 minutes, then dropped to 76% over the past five. I've heard battery calibration is bunk, but I'll try the previously mentioned app and see.
Some roms do not use a percentage because they are so inaccurate and cause the user to obsess

A little info on batteries
The important thing to remember about Lithium Ion batteries is that when you do charge them, bring them up to full charge before taking them off the charger.
They all have a circuit board in them that remembers a full charge. (If you've every taken one apart you'd see this) When you charge them this chip will restore the amount of power that has drained.
Partially charging them will screw up this function. And screw up the battery.
Deep Cycling is good for them but not all the time. Once a month is good for them.
A good rule of thumb, but not absolutely necessary is to discharge them 50% and then bring them up to a full charge. Obviously this is not always possible when playing video games or watching movies. I always try to leave it on the charger when watching movies in the cradle.
There is an app on the Market called Battery Repair. It makes an attempt to reset this chip on the battery by meticulous monitoring the charge and capacity left in the battery. Running diagnostics and setting the battery to its best state. Its the only one out there that does this.
Battery Calibration app is good if you change roms or batteries alot.
Here is what it does:
Calibration needs to be done after flashing a new ROM, but you can calibrate any time you think your battery is miscalibrated. This program does it by removing the batterystats.bin system file. The OS generates a new clean batterystats file soon, thus any fake information from the previous ROM is removed.
It's suggested, but not necessary, to let the phone fully discharge after calibration, then charged to 100% without break.
The app shows your actual battery status, and only allows you to start the calibration (i.e. removes the file) when it's fully charged, unless you force earlier calibration.
The voltage meter can be useful too. Full charge is around 4200mV.
First and foremost...lets get this out of the way..if u want more battery life..get a newer more powerful battery...thats the best option..
But if you still wanna stick with your current battery and still want improvements..here is a little something i want to tell you..
Obviously you might have searched about how to improve and come across the method known as calibration.. this is the method as described by one of our members..
nickrule1896 said:
Steps:
1. Before flashing a new rom, use root explorer (with read/write set) to delete the file "batterystats.bin" stored in /data/system/.
2. Charge your phone with it being turned off.
3. After it is fully charged(100%), take out its battery without plugging off the power supply.
4. Wait for a few moments, and a ? sign will appear.
5. Put your battery back in. You should see that the battery percentage increases quickly to 60%. If it increases to 100% with seconds, please skip to step 6.
6. If it stops increasing at 60%, let the phone continue to charge until 100%(takes quite a while)
7. Once it reaches 100%, let it charge for a further 15-20 minutes.
8. Once that's done, you can boot to OpenRecovery and flash your rom!!!

https://plus.google.com/u/0/105051985738280261832/posts/FV3LVtdVxPT
As is mentioned.. "It has no impact on your battery life" !!!
So...BATTERY CALIBRATION IS JUST A MYTH!!! Still...if you dont believe me..continue following your stupid practices..
Coming onto bump charging...
When your phone shows u fully charged it is actually charged only till 90-95% and thus u may experience a sudden decrease in battery %age after u unplug the charger...
The method for bump charging as you ardent ritualists may already know is as follows..
" Phone on, charge to full
Shut Phone off, charge to full
Phone back on, charge to full, use like normal. "
The main disadvantage of this is that it increases your battery voltage...Also in some case of sudden overvoltage while charging this can damage your battery...what for? 5% increase...
also..all that extra heat is bad for the lithium batteries...
Therefore 95% battery is good enough for daily use
so..if you really want to improve battery life...dump all these methods and just buy a more powerful battery and give it a month to give you proper results..all new batteries require at most a month to work to their full potential...
P.S. : come to think of buying a new battery...this idea may be very helpful to you if you do happen to own a Galaxy NOTE..

If this is all a myth, and I'm none the wiser, why is my battery percentage all over the place? For example, went on a hike listening to music etc. Ran the battery out. Got home, plugged into charger, turned on and it said I had 46% though when I first plugged it (while off) the battery symbol showed obviously barely anything.

Android is very....insensitive when it comes to battery .
Android keeps track of the battery using a permanently running Battery Service , which polls at a certaon interval....
For our phone , deep sleep will affect battery polling and thus your battery will be displayed as being larger than it really is .

Heyy guys I have a problem regarding the battery life on my fone
On any rom be it cm7 cm9 or cm10 whenever i charge my fone to say for eg. 65-70% and unplug the charger battery starts draining quickly until it reaches a particular point like (45-50%) then the drain becomes somewhat stable
However when i charge the phone fully (ie.100%) the battery depreciates economically (like on stock)
This means I have to charge the battery full in order to prevent for drain
What should i do to prevent this from happening? Or should I buy a new battery
Any Help Appreciated
In my experience with any lithium battery not just android increase battery life by let it die fully so it wont turn on at all then charge till 100% and no harm done by leaving an extra 20 mins leave charger in while turning on should vastly improve an older battery

I am afraid you're wrong in letting old batteries to drain completely man...when battery is new like say within 150 cycles what you said is true but as it becomes old it's better to charge it when it goes below 15...coz the chemicals will become inactive and won't be efficient in taking up charge

What about Die Hard Battery Caliberator? Got me rid of bump charging.
I have seen lots of threads about people complaining about very poor battery life after flashing roms. Sometimes battery charges to 100% quickly and discharges very quickly.
So, these are the solutions. These solutions are IN ORDER. If the first one has no effect, then try the next one. If the second one doesn't work, then try the third one.
Now-
1) Try reflashing your ROM.
2) If reflashing your current ROM doesn't work, that probably means the ROM itself has poor battery life and you should change it. Stock ROM's have the best battery life.
3) If you are on stock ROM and still having problems, switch off your phone, take off the back cover and remove the battery. If the battery is swollen or the shaped weirdly, this means your battery is dead and almost useless. You need to buy a new one.
I recommend buying only stock batteries manufactured by Samsung because other batteries can be fake, incompatible, or just used batteries sold to you. Don't buy anything else unless you're absolutely sure of what you're doing.
Hopefully I helped.
Re: Solutions to Battery Problems[Newbie Friendly]
General tips for saving your battery-
1) Switch off mobile data whenever you're not using the internet.
2) Change your wifi sleep policy. This can be done by going to wifi settings, pressing menu button and then select advanced.
You can change your sleep policy so that your wifi sleeps when the screen is off.
3) Decrease your brightness! Your screen is responsible for most of the battery drain. Increase your brightness only when you are in bright sunlight or when you're watching videos etc.
4) Switch off GPS. Keeping it on all the time also drains a lot of battery.
5) There is an app called 'Greenify' which hibernates the apps running in the background. This app has increased my battery life. Here a link https://play.google.com/store/apps/...e=google&utm_medium=organic&utm_term=greenify
6) Don't charge your phone when it's at 70%. Wait till it is between 20-30% and then charge it continuously till it reaches 100%.
7) Let your battery completely discharge once every month.
8) Don't use task killers. They use more battery life than they save.
9) NEVER charge your phone overnight. Your phone takes only about 4 hours to charge. Overcharging reduces your battery life
10) If you use a Bluetooth headset, switch off Bluetooth whenever not in use.
11) Using setCPU profiles. This is one of the most effective ways of saving battery. You all know about overclocking, but do you know about underclocking or undervolting? Using profiles, You decrease the clock speed of your CPU when certain conditions are met. These profiles can be on the basis of time, screen off/on, battery etc. So when my screen is off, it automatically reduces the clockspeed which saves battery

General tips for saving your battery-
1) Switch off mobile data whenever you're not using the internet.
2) Change your wifi sleep policy. This can be done by going to wifi settings, pressing menu button and then select advanced.
You can change your sleep policy so that your wifi sleeps when the screen is off.
3) Decrease your brightness! Your screen is responsible for most of the battery drain. Increase your brightness only when you are in bright sunlight or when you're watching videos etc.
4) Switch off GPS. Keeping it on all the time also drains a lot of battery.
5) There is an app called 'Greenify' which hibernates the apps running in the background. This app has increased my battery life. Here a link https://play.google.com/store/apps/...e=google&utm_medium=organic&utm_term=greenify
6) Don't charge your phone when it's at 40%. Wait till is below 10% and then charge it continuously till it reaches 100%.
7) Let your battery completely discharge once every month.
8) Don't use task killers. They use more battery life than they save.
9) NEVER charge your phone overnight. Your phone takes only about 4 hours to charge. Overcharging reduces your battery life
10) If you use a Bluetooth headset, switch off Bluetooth whenever not in use.
Using these tips, I have gotten almost 2 days of battery life on stock Roms and a whole day of battery life on custom roms like CM10.1 and CM7

I'm interested in the greenify app, the only problem is that it does not support stock gingerbread which can give the most juice. Do you have any other recommendations of similar apps?

Greenify is a unique app and I am yet to come across a similar app.
You can try this one but it is paid - https://play.google.com/store/apps/details?id=com.elsdoerfer.android.autostarts

Are you sure about these? Because I've read that phones only take how much ever charge that they need, so charging overnight isn't a problem. And i've also heard that letting the battery charge fall below 40% actually reduces the life over time.

Yes, I am sure and it is something I have verified.
Overcharging kills the battery.
I saw a video once of an evo 3d. The battery almost completely died after it was charged for 3 days
And you should always charge only when your battery is low.
This will ensure longer battery life

Normally, when the battery is fully charged, the chip that controls the charging process reduce the current exponentially to 0: this avoid the overcharging.
I think all smartphones have the charging chip control integrated (an USB cable is simply a power source, not a battery charger), so I hope we can leave the phones on charge all the night without any problem. I do that always and never had problems.

Well, if you see again, I never mentioned that clearing battery stats saves battery. It is for those people whose phone charges very quickly with big increments, which typically happens after changing ROM's.

It seems both of us have read conflicting and contradicting things.

Quoting Dianne Hacborn(Android Framework Engineer):
"Today's myth debunking:
"The battery indicator in the status/notification bar is a reflection of the batterystats.bin file in the data/system/directory."
No, it does not.
This file is used to maintain, across reboots, low-level data about the kinds of operations the device and your apps are doing between battery changes. That is, it is solely used to compute the blame for battery usage shown in the "Battery Use" UI in settings.
That is, it has deeply significant things like "app X held a wake lock for 2 minutes" and "the screen was on at 60% brightness for 10 minutes."
It has no impact on the current battery level shown to you.
It has no impact on your battery life.
Deleting it is not going to do anything to make your more device more fantastic and wonderful... well, unless you have some deep hatred for seeing anything shown in the battery usage UI. And anyway, it is reset every time you unplug from power with a relatively full charge (thus why the battery usage UI data resets at that point), so this would be a much easier way to make it go away."
Its just a myth mate..
And also, it's a myth that you should let ur phone charge reach 10% or get fully discharged before charging. This actually leads to decrease in the battery life over time.

I am aware of what you are saying and I fully agree.
But I have never mentioned that clearing battery stats increases battery life!
Tips to increase battery life are in the 2nd post. I simply said that if you clear your battery stats, UI will show you battery which is more accurate to the actual battery level.
Why are you arguing over something I never said?

Think of your battery as a person working out and charging is like taking rest. If the person's ability is to do 100 reps yet he takes rest after only 60 reps and keeps doing that continuously, he won't be able to do 100 reps after a few weeks!
Look at the logic mate.

I am just trying to help make your guide more Informative. Read what I have put in bold letters mate. It doesn't affect the battery level shown to you

Thanks for tips
You misunderstood me :'D
Clearing battery stats does not:
Affect battery life
Affect the battery level displayed to you
The only thing it does is, it wipes the history of battery consumption by each app. I am talking about the battery consumption by each app shown to you in Settings>About phone. If you clear the battery stats.bin file, the only thing that geta erased is this

This! Anything about wiping battery stats is not a myth anymore, so please stop misleading people,
Also "6) Don't charge your phone when it's at 40%. Wait till is below 10% and then charge it continuously till it reaches 100%."
Not true! Charging your battery around 50% is the most efficient way to keep lithium battery alive longer. A discharge once a month is also recommended.
