Guys I noticed that when checking with *#0228# the battery status and you do a quick start the battery percentage drops radically 10-30% depends of the use of your phone. I remembered that I have read somewhere about the 5% left of the charge of the battery is left when a phone shuts down so battery doesn't get destroyed. Not sure if it is true or not.
But as I see it the percentage of battery left on notification bar isn't accurate.
Please check it on your phone and post if it happens to other phones. And if there is some more tech based guys outthere, to explain give a solution or a helpfully trick.

I think even though it might not be accurate, its will always be inaccurate the same surely, so eventually you'll learn how it reacts, so it does give you an idea of what's left.

If it was just few % I would not mind on my last quick start it dropped from 46% to 18% the next one did go to 26% then 23% and back to 26%

Maybe your battery stats have gone another wrong in the upgrade, I've only done on charge so far, so haven't really noticed any difference in battery life from gb so far.

What do you mean by "quick start"? - it's a known and fairly well documented aspect of our fuel gauge chip that heavy load immediately following a reset (such as rebooting) will cause it to report artificially low.

Use the dialer and give the code *#0228# it pops the battery information on the bottom is a button it says on it QUICK START on GB it would make a quick restart it think (black screen for 5-7 secs) now it only changes the block value of the battery and the charged percentage.

Doesnt come as a surprise, the indicator is not accurate as for other devices too.
AFAIK battery caliberation is a complicated process for which one may need kernels with special features.
its not something that can be done by an app from the market....

braxos,
did you just change ROM and/or Kernel ?
If yes, you would need to do a few cycles of charge-discharge, and clean the battery status.
I only experience like that when I just changing kernel (different kernel, not upgrade), and changing different ROM (different ROM also, not upgrade).
Otherwise, when the ROM and kernel stabilized alrd, I have never experienced such things.

Read the MAX17040 datasheet. Particularly the part about the assumptions the chip makes when starting - if those assumptions don't hold true, it'll read inaccurately for a while.
We have a MAX17042 but in our phone it's used identically to the older 17040.
Nothing new, it's the same deal as the "battery estimate drops artificially on a reboot" thing.
The battery protection circuit in the pack is not based on SoC estimate, it's based purely on voltage, so will always shut the phone off before damage occurs.

No, you don't need to do that. That only applies to "coulomb counter" type fuel gauges - which ours is not.
Wait 1-2 hours and do nothing but use your phone normally - that's it. Charge it if you want, discharge it, whatever...

Entropy,
I was on rooted stock rom and Notecore kernel (v11.5). I had a very good battery with no deep sleep issues and good 'On screen battery' time.
I flashed a new kernen (v12.0 I believe) & started experiencing battery drain issues. Still Deep sleep is very fine. But on screen battery drain is huge (>25%/hr).
Since then I have altered between Notecore and Speed mod kernels, but the issue persists. I have almost tried very method suggested in XDA to callibrate battery but no improvement seen. I am worried whether my battery is aged, but its only 9 months old.

nice, did you try cleaning before flashing the kernel, like jbroidscript?
Not all kernel versions are very good for battery life.
Did you also check if your battery is getting full charge? with android sensor you can see current charge left.
Screen on drain is usually around 25% unless playing games then its more. Note only is capable of 3-4 hours screen time with no games, with games its less.
just a few tips.

Thanks baz77.
Can you please guide me to correct Jbdroid script. The one i foound in XDA is put by JBlank and many senior members are calling it useless.
Battery charging is fine. Atleast all teh tools like Battery monitor widget, inbuilt, Badass monitor and as suggested androsensor are giving the same % readings and informs battery health to be good.
But its not a placebo effect. I can really battery draining nothing like before.

I guess the only way for you to find out, is take out the battery and compare it to a real genuine samsung battery.
In software this shouldn't be possible.
Although this thread is damn old: Simply delete batterystats.bin OR turn off the phone and let it charge to 100% when off. This also happens when you use an extended battery.
I too tried it before quick start the battery level was 56% and after quick start battery level dropped quickly to 26%

It seems as though battery life is one of the most common topics among us vibrant owners. We are always looking to increase battery life, whether it be with a new rom, new kernels, or apps from the market. I wanted to start this thread for everyone to share their experiences, tricks of the trade, etc on getting the best battery life.
Post pictures, rom info, kernel info, app info, modem info, battery info etc! No pic, no proof!!!
This is the best I have been able to get with my phone with:
Bionix 1.3.1 - Stock kernel - KB1 modem - TW launcher - auto brightness off, set about 2 clicks from the left - battery calibration app used at 100% - Stock battery. Light / Light moderate usage, phone calls, texts, web searches. GPS on.

Well, this is great battery life you got there For me 24h is the most I can squeeze from my Vibrant with Project V/Bullet 1.42 kernel, auto brightness off, moderate usage. 16h with heavy usage... It's fully charged now so I don't have pics to show it
i used around 5% with in an hour with somewhat heavy usage this is cm7 nightly 71 bali with uv
srdjav - have you tried bali uv? I heard it works really well, especially with bi-winning, but I have heard great things about it on all different types of roms
gamikzone - impressive for cm7, I have read horror stories that the battery life on it wasn't all that great...but I guess with the kernel script and bali, it's way better!
@corpsetomb
Yes, I did tried Bali... But honestly, didn't see much difference in battery life. I have tried 4 different kernel on Project V and battery life was always 16-24h, depends of the usage. With extremely heavy usage 16h... So i decided to stay with Bullet 1.42.
But I didn't try Bi-Winning ROM yet... Maybe I will give it a try
But I had very bad experience with Super_DragonMODz 1.5 kernel... For a few hours everything was ok. But in one moment I picked up a phone after doing nothing for a half an hour and it was HOT! And I could smell "burning" inside Luckily when I took battery out and let the phone cool down, it was ok
Can we see pictures not words :/

haha what is this, a courtroom?
truly, none of this matters. one big factor in battery life is application use. in order to pinpoint someones battery usage, one would have to list, in detail, their application usage. which/how many apps poll for background data/how often? is the person using an autokiller/ram optimizer? which/how many apps stay open in the background, even when killed?
The bottom line is, battery life is ultimately determined by the user. there are only so many differences, in terms of battery, between these roms and kernels. none of them will give you a SIGNIFICANT difference. this is not the fault of the devs, they are not magicians.
This is why people do not get nice responses in rom/kernel threads when they ask "how is the battery life?". Then some clown who is a very light user will say "its great! i get 20hrs per cycle!!" and then you flash it expecting ground-shaking results...only you forgot that you have 317 apps on your phone (20 of which are constantly poll/checking for background data), and you use your phone/data like a whore who youll never see again. and unfortunately, there are horrible noobs out in there who, after doing this, will actually go back into the thread and say something like "DO NOT FLASH, MY BATTERY DOESNT EVEN LAST 8 HRS!!!!"
Theres only one true way to REALLY compare battery between ROMs/kernels (and it still isnt 100%trustworthy): download a ROM, try it out for a few days at moderate usage. Then flash the one you want to compare it to. Make sure you have the SAME exact setup as the ROM before (apps, brightness, GPS on/off, background data, etc.), and try to mimmick your usage with the other one. NOW you can effectively determine, relatively, which ROM may show better battery results for everybody. and then, when someone asks "does this have good battery?" you dont just say yes; you say "yes, i have seen noticeable improvement since coming from _______ rom, i about ___hrs more per full charge "
sorry for the rant

No worries, I welcome your input! I agree that a big factor in battery life is application use. You will see in the OP that I recommended people put in as much detail as possible along with their picture, such as what type of use, kernel, rom, etc. I would also like to hear and see comparisons between roms, that is part of what this thread is all about! To be able to compare different roms and see what helps based on usage.
Thank you for participating and your input!
Note: Do you guys think I should start a list of best battery life in the op?

You can manipulate the battery use stats pretty easily... at least on CM7. If I plug my phone in to charge for an hour, it doesn't reset my battery usage. Sometimes when I look at it it will say 24 hours+. Which I know is not at all accurate.

Do you have baterry drops while using? Like from 30% to 15% ? Cause i've found that and that's not cool
Sent from my MB525 using xda premium
Hi guys, I wouldn't accuse ROM or kernel, more I wouldn't bother too much, till I do not have to charge twice a day.
I have the same issues with two different phones at home, different kernels and different ROMs. Though I tried batt calibration and CWM wipe, it does not help. Both phones never reach 100% - go to 99% even if you charge for several hours then.
Sometimes I have 7% drop per 8 hours, sometimes 5% in 20 minutes - both cases only 2G is working (and of course some mess in background ;-)). I would rather accuse some applications working in background. Anyway rebooting helps.
For the case of sudden drop by 15% - do you have any task killer killing your batt widget? Or, may be, your battery widget is refreshed once per hour or so? Just proposals to check. (it is funny when task killer kills your clock widget - might be a lot of fun when you suddnely find you are two hours late. Know such case)

The 100% to 99% when you unplug is not a problem. its because when it calculates the battery "%" it always takes the lower value
Example:
Battery level is 80.9 -> shows 80
Battery level is 99.999999999 -> it shows 99!
that is not a bug
Mine is also having this problem. Jumps from 30% to 20% instantly if the phone has been fully charged. However if I only charge it to 50% it does not jump.

NOw i am using wiui and cant charge more than 81% ( defy plus )
Mine also drops instantly to 99% after unplugging, however it does not seem to affect the functionality of my phone. I got usually 40ish hours with ms2ginger4 and now I am testing it with quarx ics 0413 defy+ build to see what that drain is.
Also every time I install a new rom I use.

Works great for battery charge issues
Well in my case the problems came when I started changing roms frequently ... bought defy around September last year, started the custom rom changing week after purchase ( rom changing frequency was about a different a week ) ... and battery skips started happening around December . .... and from then m always searching for a solution to it ..... unsuccessfully
Seeing how a new firmware came out on the Nexus S, I want to see what kind of battery life everyone is getting on Android 4.1.1 Jellybean. And since everyone cares about battery drain one way or the other, we can use this thread to post tips on getting more battery life and/or try to figure out what's causing battery drain.
---
Anyway, PLEASE include these when showing your battery usage:
What ROM/kernel/Governor you're using
A combination of the three can determine why/how you're getting the battery life you're getting. Also, post thread link for the ROM/Kernel if you can.
SCREEN ON TIME
Probably the most important thing to know when determining battery life. Since the screen uses the most juice and generally the amount of time we'd be looking at our screen, the screen on time is very important to show. You can get this by going to Battery > Screen
YOUR GENERAL USAGE
How you used your phone is another important determining factor of how your battery was used. If you took pictures or listened to music, that would explain why you got such low battery life. More information the better.
IMAGES
Images help as it gives information which would be probably be too difficult to describe. The Battery section in the Setting section would help as would Battery monitoring apps
A simple template would be the following:
Code:
[B]*IMAGES[/B]
[B]ROM[/B] -
[B]KERNEL[/B] -
[B]GOVERNOR[/B] -
[B]GENERAL USAGE[/B]
blahblahblah
[B]CONCLUSION[/B]
blahblahblah
----
ADDITIONAL TIPS
- Show images of CPUSpy. May help see if your CPU is running out of whack or if, for some reason, is running on 1000MHz too much.
- BetterBatteryStats app screenshots. It gives a much better detail on what's waking up your phone, what apps are using it, and so on. You can buy it HERE. It's a very good app to monitor battery usage.
- More images the better. So we know what's going on with your phone.
PLEASE DONT
- Embed too many images to your post. It'll be too difficult to look at this thread with hundreds of images being embedded at the same time. Plus, people looking on mobile phones would probably struggle opening the page. If you have a lot of images, please just post the link and not an image
Anyway, thanks! Hopefully we can get amazing battery life on Jellybean!

ROM - Jellbean 4.1.1 OTA from here: http://goo.gl/AXr2d
KERNEL - Default/Stock kernel
GOVERNOR - Default/Stock
GENERAL USAGE
Usage was, in my opinion, light and didn't really do much. Most of the time, I was on 3G only to go on WiFi when in a Starbucks. I turned off my phone when watching The Dark Knight Rises and trying to save the most battery but that didn't really seem to help. I used the camera once in a while but didn't listen to any music.
CONCLUSION
So far, this battery seems kind of... bad. Especially with my usage (which I thought was light), I thought I could get more screen on time than just 2h 14m. I'm a tad disappointed and might go back to ICS just for the better battery life.
ROM: Unofficial CM10 by Lego
Lazy gov. Air kernel test 112.
The 2 hours of screen usage were from playing temple run, xda, and fb.

That's a good cycle IMO ^. Have you done a factory reset OP? Force of habit has me doing it anytime I do an update to avoid any issues. It also seems like you have a crappy signal at times. I haven't had a chance to actually judge battery life but mine seems to be on track to be about the same as it was as on ICS though.

It's weird because I'm using the same radio as on ICS and I seem to be getting worse signal on Jellybean? I might reflash a new JB ROM and try that instead.
I have a 2300mAh battery on stock JB i might upload some screenies later but i havent seen the battery life decrease it seems to be the same

Yeah. I'm gonna probably go back my KF1 radio once I update my ROM tonight.
IMO I always do a preliminary test the battery when the phone switch to airplane mode in a night, if the drain only 1% then the ROM is quite good.

Right? I miss the GB battery life, could leave GPS and 3g on all night, not touch it, and lose 2% in 10 hours. With ICS I was grateful if I could get it down to 1.5%-2% in an hour. And Google Now is too awesome to turn stuff off for, so JB is even worse

My battery life is absolutely horrible. I think my battery is bad though. I've had it since I got the phone. When the nexus came out.

Its one of those pay to play situations. My job has places for me to safely charge my phone so the battery isn't too big a deal for me. Best bet is to carry a spare charger. It is after all a pocket computer. Sucks, but until battery tech catches up, there isn't much us or many other smartphone users can do.
I think the background sync drains battery when idle. With sync on during idle, the batt drops ~3-6%/hr. If sync is turned off, it becomes ~1%/hr. (using 3G)
Exactly what Google things syncing would cause such a drain? I have this type of usage but all I have is Gmail syncing and I only get a few emails a day. I have obviously noticed increased life disabling Gmail, but how could it be using so much if it is push?
I'm getting, at least, the double than before...stock, unrooted
I don't understand this.....
The only thing using CPU is Android system at 5-15%... why is this happening? The screen was off for at least 8 minutes
Sent from my Nexus S using xda app-developers app
Since it just started up, and I'm guessing it is syncing like crazy. Calendar, instant upload if you have that in G+ or drop box chrome, contacts, drive, Gmail... Etc. Location is happening (maps, and latitude), checking for updates, weather. Check again in an hour and see if it has settled.

I havent noticed a problem with my battery. It's actually been pretty much the same. I go almost the entire day not charging it on normal use (almost 12 hrs). Heavy use with me is constantly playing games, I get maybe 3-5 hrs depending on screen brightness. It's pretty much the same as ICS for me
OK so i installed almost every ROM on there and here is what i found.
TOP.
:good: CleanGB ---- Takes the crown, super fast battery charge in less then 45minutes the battery is full. Over a period of 8 hours in stand by(as i sleep) the battery did not drop at all.
CM9 ---- Took over 2.5 hours to charge the battery, in 8 hours it dropped 12% battery life.
CM7 --- Charged in 1.7 hours and dropped 17% battery in 8 hours.
The rest were terrible, I would not even bother.
All configuration were the same. Everything off (wifi, gps, etc)
After all i installed CleanGB again at the end. And guess what in the past 8 hours battery did not at all in standby. My phone last 3 days on the same battery charge again, with normal to moderate use.
This was the same battery same settings.
Let me know if you guys found something else.
GUI experience:
CleanGB is cool and simple, however i wish they would upgrade to Android 4
CM9 has an really cool interface but i can not tolerate the battery drain issue.
CM7 is the worst of the two, not so great GUI and bad battery life.
If you still think im crazy install CleanGB and see for yourself. CM9 just needs to focus on the battery drain.
CleanGB is more focused on the phone working as it should and they did that really well. :good:

CM10 isn't horrible, I think it's a step above CM9 honestly, Mine charges over night so i don't know how much it would drain. during a day of moderate use (texting, reading XDA and what not) I'm generally about 65% or so (If not higher)

I will try CM10, i didt think it was available for the epic. I do like the CM9 look but i hate the batter if CM10 is better then ill be happy.
Thank you. I will report findings.

The People's ROM. It's as good as CleanGB (ran that for several months) and is based off the latest official release (FC09).
My one personal cheat is to use the CleanGB kernel with TPR, so that may be why I get fantastic battery life.

Never going to happen. CleanGB (and TPR) are both stock TouchWiz based ROMs and it's not too likely that Sprint will offer an ICS update for the Epic.

ROFL!!! :good:
As to the topic, I have seen it posted by a massive number of users, that CM7 had much better battery life than CM9.
In fact, the number one reason I saw posted as to why people went back to CM7, after checking out CM9, was battery life.

This 100%
I' am on Cut & Paste Rom FC09 and this has given be best battery life as of today. I had clean GB earlier (sometime back) after which i tried all the other Roms (AOKP - ICS, MIUI - ICS, RandomRom 5.1) and then decided to try C&P and man this rocks !
I have got a battery life of 2 days with a talk time (voice call) of 4 hours and thats the best i have seen till now among all of the Roms on my phone
legendary.mtd + gps fix is just as good as cleanGB plus it has the 15 toggle mod
try AOKP, people says it has better bettery life than CM9, so you can keep the "cool interface" while saving battery lol. Me myself never bother with battery as long as it last more than 1 hours. Always carrying one of those portable charger, If the battery is low then charge it haha.

+1 for aokp...with the nexus modem. Typical 3 hours screen on time, over 18 hours on. Time with out signal under 4% every day. Used to be around 15% with epic modem under same conditions. Using 1800 touch battery.

The rest are horrible..? Thats not very nice, if your looking for a battery saving ROM, you should definitely try The Peoples Rom (TPR) and if your not satisfied with thatt, try Cut&Paste Rom. Those two ROM's are awesome.

On AOKP I enabled fast charge once, if you don't use it at all while it's on the charger I think it'll charge in 45 mins.
EDIT: here's a screenie from AOKP with fast charge enabled

Hmm perhaps I need to have didhiy do the kernel fix. There's a fix on the nexus s since people had the same problem. So far, I've only seen you and another person on the epic having that issue, which is odd. Talk to him though, since he fixed it somehow. His name is popssracer.

In my personal experiences, the newest Cut & Paste ROM has AMAZING battery life. I can get over a day easily at home all day with no charge, and maybe 15-24 hours out in the world (I'm a professional touring musician, so there's times where I have NO charging source at all).
What I noticed also has equal or better battery life to TouchWiz are MIUI ROMs. If you can manage your power usage and turn off data services when you aren't using them, I could EASILY get days out of battery on 2.1.6.

I would say if you know how to manager your data when you aren't using it EVERY rom can get great battery life... even cm10...
So this has been happening with my battery lately - it's chugging along no problem, then the second my phone hits 30%, it dies completely, and when you hook it up to a charger, it starts charging from 0%.
This has happened with multiple replacement batteries already. Anyone know what's up?

Was an issue for me back when my battery was bulging. You might want to try and recalibrate the battery if it's new by charging it overnight, if not new then get a new one. If that doesn't help, factory reset. If problem continues, take it to Samsung.

I had the same exact problem with mu Note 10.1 2014 edition. Then I downloaded a battery calibration app. The one I downloaded is made by a developer by the name NeMa. It worked as stated. Couldn not be happier. But, it needs Root. And does not ask for ridiculous permissions. Give it, or another one a shot and report back.
Sent from my SM-N910V using Tapatalk
Guys, for years now it's been proven that battery calibration is a myth. The act of charging the battery to 100% has the same effect as it does the same thing as a battery calibration app: delete the batterystats.bin file.
The problem is either with the battery or the charging circuit in the phone. Take it to Samsung and have it looked at, because a battery calibration app won't work here, despite claims to the contrary.

It has been proven as much as evolution. And that is about zero. No proof. It is a theory. Now, you are of the opinion that it is a myth. I am of the persuasion that it is not. Seeing as my Note 10.1, SGS3, and SGS4 all had battery issues for long periods of time. Then I remembered that there is this "myth" called battery calibration. After trying out the "myth", my wife's phone no longer shuts down randomly, my Note 10.1 does not go from 30% to dead instantly and neither does my SGS3. All have batteries that now last exactly as long as the manufacturer specs them out to. And non of them freez up and or shut down any more. All of these devices have been going through these problems for many months now. Tried the "myth". No more problems for this past week. And there are not going to be problems.
So, in my case, the "myth" has gone from the act of being "myth" to fact. Until your device start acting up where battery stats play a roll, then it will stay as such. A myth. Now, if the battery has been through to many charging cycles, then it is probably old and on its way out. In that instance, no battery calibration will bring it back from the state of dying. At that point, it is time to get a new battery.

So you belive everything that you see on TV as well? I suppose that the Internet must be God to you. I mean, there is an http link for everything. Must be fact.
How would you like to explain what happen ed d to all three of my devices that were having g battery issues. SGS3, Would charge to 100% drain down rapidly and when it hit 30% it would just shut down.
SGS4, would drain down to nothing at random and shut down at random. Even in the middle of a call. Note 10.1 2014 edition would drain down extremely fast, and I mean fast. It also would shut down. That one I did replace the battery on. And it still did it. All of these problems have persisted for several months now. Only a week ago did I try the calibration method. Which I am aware, using an app is the short way around deleting the file for the battery. At any rate, all devices are back to normal operations. By the way, I put the old battery back into my Note 10.1, and did the recalibration. AL is well with it also. But, the Internet must be telling the truth. Plain and simple, calibration will not fix a broken battery. It will however reset the part on the system that reads the battery correct and tell the OS what to do with those numbers. In the case of the case of these, my devices, there are no more shut downs happening. Or was all that in my head for months? Probably just a placebo effect? Yeah, that's what it was. The Internet says so. Lol! I'm going to put up a link to a YouTube video that shows that horses are pink.

By the way, I am just having fun with you and bust your chops. Lol! But I still stand by my statements of calibration. It works in some scenarios. Particularly when switching ROMs.
Sent from my SM-N910V using Tapatalk
On my old Gingerbread device, I used Nema's Battery Calibration app. Once I read the information from the Google engineer in the link I provided, I stopped, and haven't touched a battery calibration app since. In my experience, calibrating the battery is a needless step, because you aren't actually doing anything to the battery itself or the circuitry within it. For example, you mention using it after changing ROMs. Why? My battery life has not been affected from all the ROM switches I've made in the last year, and I've made plenty of them.
If a battery calibration app were to actually recondition the battery, then I would say such an app is useful. Instead, you have a placebo effect brought about by an app that does nothing that Android itself doesn't already do. So why waste the time, the energy, and the (minuscule) storage space?
Google make Android. So if they say that batterystats.bin has no effect on actual battery life and such, then it must be true. I mean they are the ones who made the damn file, they should know what it relates to.
The reason why your 3 devices worked again after a battery calibration might be something else. Maybe the app you used did something else other than just delete batterystats.bin file.
I also used to calibrate my battery on my old Gingerbread device. But honestly, I didn't see any improvement in battery life by doing this. Nor did I see any worsening in the battery life or sudded death by not calibrating.

First, Google did not make Android. They purchased it and now modify it. But that is besides the point.
Sorry, but the app that I used did one thing and one thing only. And that was clear the file. It did nothing else. Can you tell me what if not battery stats, would make all three of my devices behave properly? Because I would love to know, as would the rest of the community. I seriously do not particularly care what Google stated. I care what was happening with my devices. And they were not working. I used an app to clear a file that has to do with the batteries. All of my devices work exactly as they should. Google can tell me that all rainbows are silver. But, my devices are not telling me one thing about my batteries while something else is the case. And my devices are not shutting down on their own either. So, 3-4 months of serious charging, readouts , and performance issues all cleared up after the use of an app. I am confident coincidence is not the case. But thank you for your disbelief in something. Absolutely appreciated. Plain and simple people, if you are having batteries issues. Try the simplest method. A calibration app. If it works, then great. If not, move on to the next step. Try different charger and or cable. If that fails, chances are that the battery is on its last leg. Replace it. Nothing more, nothing less. Zero arguments to be had. Nothing to prove. Or disprove. If any one is of the persuasion that a calibration app is a waste of time, don't use one. Also a simple thing to not do.
