For some odd reason my battery icon shows 71%, but if I go to batt status it shows 62%. I flashed a diff batt mod and it changed to the new one, but it's still on 71%. Any ideas how I can make it show the correct status?

let the phone run till it dies and then charge it. that should reset the battery gauge.

Never let the battery drain to zero, it's bad for you battery. These aren't the old Ni-Cad batteries from the 80's but Lithium ion batteries If you want to reset the battery stats just download Battery Calibration from the play store. Charge phone to full and then hit Calibrate and it will reset your stats. Unless something is different with the GS4 or their TW OS any newly installed rom should have this done after installation
Here is info on what you should know about today's batteries.

The statement about li-ion not being akin to ni-cad is correct. The rest is not.
No app is capable of battery calibration. The myth of wiping battery stats to calibrate the battery was clearly and concisely debunked a year and a half ago. Apps such as Battery Calibration ate pure snake oil, as they do not affect battery indication in any way, shape, or form. Additionally, there is absolutely no benefit to wiping battery stats after flashing a rom.
The fact of the matter, as verified by Battery University, is that a complete discharge/charge cycle is the only method of "calibration" available to an end user. By performing a single cycle, the charge and discharge flags are reset. Only a single cycle is needed and this is something that need be performed more than a few times a year, as it wail shorten the battery's serviceable lifespan.

There is a far easier way to clear battery stats. Charge to phone to full or near full, and then unplug it. Voila! Regardless, wiping battery stats is not going to do anything for the op.

Well a friend of mine had the same issue with "stuck battery %" and that did the trick soooo just helping out with what worked for another is all. whatever
That actually didn't do the trick, as nothing relevant to reported charge is contained in the file that is wiped. While it may seem logical to ascribe the fix to a proximal act, it is actually a case of post hoc ergo propter hoc.

Neither did this. The battery calibrator app did nothing either. My phone is still showing a percent up top that is not what shows in settings/more/battery. More news, my phone showed this morning, after I unplugged it from all night charge, that it had been running on battery for 8 hours 2 minutes. The whole battery status is fubar somehow.

That's the only thing I haven't tried. Will do that today. Will report.
Didn't work. Gonna have to dirty flash the ROM.
My S4 (2 months old) dies with the battery at 20%. After reboot (plugged in) it still says 20%. Why does that happen? It should say 0%!
Update
It seems that the battery gives an incorrect fake voltage sometimes. To correct that I turned the camer flash on, using a flashlight utility, and after a few seconds I clicked the quick start button in the battery calibration utility you can access dialing *#0228#.
Now it show 11% that should almost be correct, and it's now charging. I am charging it in slow mode at 500mA just to give it a proper charge.
I'll update you as soon as I have results.
Second Update
Nothing. I think the battery is broken.
It dies at about 20%-30% and when the phone restarts, plugged in, it says it's 20%.

Charge to 100%
Boot into recovery
Wipe battery stats
Reboot
Don't unplug charger until at desktop again (You could debate this one, but that's when I do it)
And don't worry about killing your battery, it'll do more harm than good.
Explanation - When you wipe battery stats, it tells your phone you're at 100%
So, if you wipe when you ARE at 100% you'll get accurate readings.

The past 2 times I did this, the phone was turned off and plugged in and charged over night. this morning I wiped the stat, but i do not remember if I had unplugged it before it finished booting up. I am charging it now, with it on. When it reaches 100%, should I reboot into recovery and wipe it or should I let it run all the way down?

Down to say some were around 20 - 5%.
As far as I understand that shouldn't be necessary, and could weaken your battery.
As long as it's fully charged when you wipe the stats you should be good to go.

Ok...I have ran the phone like normal. Within 6 hours, I am down to 62%. I rebooted the phone, and it still shows me at 62%. At least I have that fixed.
Now, I see some people use OverStock and seem to be getting better battery life. I just want to get about 16+ hours out of my battery. Right now i seem to be pushing 12 hours. What is the tick that i am missing??
For every hundred vibrant users there seems to be a hundred different accounts of battery life, and a hindered different opinions on how to keep it down. 12 hours on the stock battery is pretty good, especially compared to stock.
Mine'll last me around 15+, if I left it not charging, i think.
I'm on overstock, the screen is at the dimmest 95% of the time, and I use setcpu. 1000/1000 with a screen off profile of 200/200. So, that works for me pretty well.

You need to recondition yr battery as posted above, 2-4 cycles. But i prefer to re-flash ROM when battery 100%, should you get proper batt stats.
You may buy new one to test yr system n batt stats, also good for spare. Or just borrow yr friends battery, just to check yr rom n batt stats. Treat it like you did before.
Good luck.

Hello,
I have ordered a new higher MAH battery for SGS II . I may be running stock ROM/Kernel or any of the custom AOSP ROM/Kernel.
During the kernel/ROM updates I have read that we dont usually need to clear the battery stats (since we are using the same existing battery).
However I will now be using the following battery :
http://www.amazon.com/gp/product/B0058SJ5Q4/ref=oh_o00_s01_i02_details
I need to how to properly calibrate the battery status so I can achieve full charge and maximum run time from this battery. Do I need to clear battery stats (from recovery mode) first and then insert the battery for first time usage or otherwise.
Have read a couple of posts on the subject however none provides a clear defined and fixed approach to the issue.
Any detailed guidance would be appreciated to be of benefit for the community in general.
Thanks.
=================================
Guess there are already enough methods and ways and some even debunk the myth that does the phone really needs any type of calibration/calibration apps at all or not.
Will try diving into it directly to see the effects myself if any.
You don't need to do anything other than sticking it in your phone.
When I got the 2000mah battery, I found my battery life to be equal or even slightly less than the stock one. I fully charged the battery, went to cwm and wiped battery stats, used battery completely till it died and then fully charged once again. It did seem to work as my battery life was much better.

He's right. Your battery calibrates itself with a full charging.
i read in a number of articles that you should reset/wipe your battery stats with CWM once your battery is at 100%, then switch off your phone and connect to a charger usb/plug until it will be charged to the actual 100% (usually only 1-2% at most)...

All 100% wrong .
As it only wipes the stats that show and plays no part in calibration of the battery .

thnx for the correction, what do you think about "Battery Monitor Widget" app? Does its function to calibrate actually work?
Got intrigued by the issue...
No, it doesn't. Due to hardware 'limitations', battery apps can only provide a rough guess at best of charge remaining, discharge rate, etc on SGS2.
And genuine (made by Samsung) batteries don't have to be (and cannot be) calibrated. There's a fuel gauge chip in the battery which does this automatically.
Some people having issues with the battery report charging to 100%, removing the battery for a few minutes (so the fuel gauge chip doesn't have power for that time) & putting it back in the phone fixes their issues, but even that sounds like voodoo to me.

I have a extended battery. I usually get 2 days use on a charge. about a week ago I cannot make it thru a day. The battery is only about 6 weeks old. I tried another battery and same thing. I use task killer and app cleaner and have restarted several times. When I look in battery usage is shows the Android OS using 24% Display 26% and phone idle 24%. I did update all my app and this seemed to help just a little. Anyone have any suggestions before I return my extended battery or do a factory reset. tks in advance.
have you tried draining the phone completely till it shuts off, then plugging it in and letting it charge to 100% with the phone powered down?
Battery instructions say NOT to every let battery drain to 0. So not sure I should try that.

That is about the life that I get on mine on a bad day. Now that you have had the phone for a while, more than likely, your battery has not changed but you have installed more apps which are draining you battery even faster. You shouldn't use task killers either, they screw with the roms built in memory management. However, if you must, then use "Task Manager" the built in stock task manager to end apps. Also i agree that you should completely discharge your battery and then let it recharge completely without turning it on and without using it.
PS: You have a nice avatar. Conservative til i die

This is not true. The phone has its own power management. When you reach 0%, the battery has still at least 3100mV (on mine it's more than 3200mV).
Li-On and Li-Pol batteries are designed to operate between 4300 and 3000 mV when they reach more or less, than they are damaging.
So you can charge and discharge your phone everyday between 100 and 0%, without any battery damage.
Other thing is Android power management, every time you wipe battery stats or restore backup, or you spend some time in recovery, Android doesn't know, how much capacity is remaining and you need to make more charging cycles, to teach it again and get full capacity from battery. I still don't understand this kind of management in Android.
I've tried all the battery stuff. No dice still discharging fairly quick. In the Battery Usage section It still showing Android OS using around 39 to 40% usage all the time. I have done a full factory reset on the phone 2 days ago and still same.
I noticed, you are using the task killer, stop using it, you have probably loop of killing and starting of some services. Task killer kills, android starts, again and again...
I have uninstalled task killer restarted the phone and still got the high Android OS usage showing.
You won't notice any difference immediately, make one discharge, charge and discharge cycle and you'll see.
Do NOT discharge the battery completely. Over discharging Lithium ion batteries can be harmful to them. Here's a great article going into probably a little too much detail but it gets the point across: http://batteryuniversity.com/learn/article/charging_lithium_ion_batteries
As far as your problem goes it may be an issue with the phone itself I've seen a couple photons that needed to be exchanged due to issues that sound similar to yours. If it's doing the same thing on a different battery I'd take your phone into a sprint repair center, you could also try a factory reset if you have not already done so. If your only seeing this behavior with your current battery then I would return it or request a warranty replacement.

root your photon (if not already rooted) and download battery calibration from market, also after rooting go to android development and download th3bill's extended battery mod

Yes, there is an additional reserve that the Smart chip will protect by turning off the battery once it reaches the "0% mark". The Smart chip will also continue to drain the battery further past the 0% mark eating into this battery reserve. Now one full discharge like this probably would not hurt the battery as long as the battery is recharge within a reasonable amount of time. However it certainly does nothing to benefit the battery health whatsoever and it is never recommended to let a battery fully discharge. There are some practices of only charging the battery to 75%-80% that can improve battery life, but individual run time will be sacrificed. My recommendation is if the battery is under 65% than to charge the battery if it is possible to do so.
After doing a factory reset the same problem remained. Sprint exchanged the phone for a new photon. Put my extended battery back in and so far no problems at all with the exception of not being able to join my contacts with my FB contacts.
I have been discharging my Photon and previous phones to 0-5% at least 3 times for a week and did not find any difference in capacity, compared with the new battery. Lasts from the morning to the evening. If I should charge it on 65%, then the phone would be unusable for me.
Like Schale said it could be an actual phone issue, but i highly doubt it. I would try some things before assuming its a problem with your phone. Do this... Also this assumes you are unlocked or at least rooted.
1: Factory reset so to start fresh with no crap applications (task killer apps do more harm than good, as do most battery saver apps)
2: Drain battery till the phone shuts itself off (Dude what right about it reserving a certain amount of juice to not cause damage)
3: Charge to 100% (Dont use the phone during this time.)
4: Use a battery calibrator app (rooted) or recovery (unlocked) to wipe the battery stats.
5: Drain power as fast as possible till phone shuts off
6: Charge to 100% (Again, dont use the phone during this time.)
You can now use the phone how you normally would. If you don't notice a drastic increase in battery after discharging and recharging three or four times over the next few days, I would be comfortable in assuming it's a phone problem. Good luck!
Firstly, I apologize if this is a total annoyingly noobish post, but I've not encountered this issue before.
Currently when charging, my phone hangs at 99% for over an hour before hitting 100% charge. Additionally, when not charging, the phone will hang at 9% charge for longer than expected and rapidly deplete below 9%.
Info that may be pertain to the problem:
When I got my Rezound and the extended battery, the first thing I did was root the phone and flash Amon Ra.
I waited for the battery to fully charge, then I flashed CleanROM Kang Tapped Edition. I finished my general phone setup and app install stuff and had about 15% battery left (it was now about 8am, pulled an all-nighter.)
An hour later, I get a phone call and what amounted to literally 9 straight hours of phone talk time with only that small amount of battery left. I had to be plugged in pretty much the whole time and I think when I had under 10% battery when I finally got off the phone.
I have tried wiping battery stats after hitting full charge in Amon Ra as well as using the battery calibrator app. After I fully charged and cleared stats, I waited for the phone to deplete the battery before fully charging (I try to let it charge uninterrupted).
The issue still seems to behave exactly the same. Is it possible that I messed up the battery some by talking with low charge and plugged in for 9 hours?
Thanks in advance for any info or advice.
Try reflashing your ROM. I had the same issue with my phone. Assuming your rooted, try zep's battery calibrater script.

I am rooted. Looking inside the Die Hard Battery Calibrator script seems to just clear battery stats, which, I believe, happens when the phone is fully charged anyways.
I have been trying the app "Battery Calibration", which also clears battery stats.
There is also the option to wipe battery stats from Scott's tweaks, as well as Amon Ra.
I guess after all the conflicting viewpoints I've heard regarding battery stats, I'm about as confused as ever. I thought that battery stats merely stores data about the power usage, and doesn't actually affect how the OS reads the battery percentage. It boggles me that the OS wouldn't just know the battery voltage, and therefore the remaining charge. Unless batteries have varying voltage (like the Rez 3.7V battery vs the 3.8V battery), this should be more accurate than whatever the hell it is doing.
I'll give the script a shot, I'm just perplexed.
Anybody know of a widget that shows just the mV? Then I can forget about these darn percentages.
*EDIT* Battery Monitor Widget can do mV, among other things.
I wonder if I should try the HTC method contained in the link below:

Here is some word on battery stats from a Google employee:
https://plus.google.com/105051985738280261832/posts/FV3LVtdVxPT
Although there are similar reports of battery issues, I haven't found anyone with the same issue. I have an SGS2 running 4.0.4 - all stock and although I'm on Orange, it's not an Orange handset. It's just over a year old.
Since being on 4.0.4, I've noticed the battery level drops when I switch it back on/reboot. It has been dropping by 20-30% but recently it's been dropping all the way to 1%. It has also taken to switching itself off with no warning (or shutdown) - I can only assume because it suddenly thinks the battery is at 0% despite what it was seconds beforehand.
As a typical example, it was charged to 100% (4200mV as shown via *#0228#). After a few hours standard use, it was around 60%. Then, seemingly when I'm doing something intensive like recording video or downloading something over a data connection, the screen goes off and I realise it's dead. I restart and the "battery critical" warning comes up - 1%. It dies again and I remove the battery for a minute, put it back, then power up. This time it says 9%. Then after a short while it dies again. So I connect the charger. After a couple of seconds, the battery charging indicator shows about a 1/3rd full. I switch on and the battery is now at 46%. Whatever the issue, reattaching the charger seems to rescue it - even if it's not back to the original level. The charge levels (in mV) seem to match the percentage.
This happened so much that a few weeks ago, it wouldn't even start and I had to wipe and reinstall everything. It does work now, but still crashes at least once a day. I'm not sure what else to do other than wait for Jelly Bean and hope that will miraculously fix the problem.
I have attempted "battery calibration" though it's a bit difficult - and I've read that it doesn't actually work anyway.
I am a noob - so please treat me like an idiot in case I've missed something obvious.
Thanks.
Dude, I believe it's time to buy a new battery.
1.Battery Calibration apps don't work(They don't do anythight good) Battery calibrates selfs...

3.And I think too that Insane gauge chip is very crazy...(You can reset it maybe helps... need flash Syiah and Get Stweaks)
I have the exact same problem, see this thread: http://forum.xda-developers.com/showthread.php?t=2062056

Yup, battery calibration is a myth. Google already states that you do not need to reset your fuel gauge for ICS/JB devices. All battery parameters are automatically reset when it's 100% charge.
