Check device hardware info app from playstore

Accubattery from the play store is the best app for charge speeds and battery capacity. It can also set an 80% charge alarm so you can get more life out of the battery by reducing wear on it. That app also accuratly reads the battery capacity and estimates the wear on it too.

how much capacity it shows to u ?
mine showing 91 percent only , just used for 4 months

For me ampere app is showing this

It might your device's battery is not correctly calibrated. Try using some Battery Calibration apps in the Play Store.

Calibration of batteries Li-Ion or Li-Po is a myth. Using calibration apps doesn't really help as the battery files in system (to which these apps write) are renewed and the previous is data erased when you charge/reboot.

extended battery not lasting longer?

I recently bought this battery: http://amzn.com/B002MRA8FQ
However, it doesn't seem to last longer at all compared to the stock battery. I thought that maybe I needed to drain it fully and then recharge it the whole way before it would work properly, but I noticed that it was reporting 1% life left for a good hour or so before I gave up trying to drain it. Is it possible that the battery life isn't being detected properly since its not the stock battery or is there something else going on that it lasts exactly as long as the stock battery?
as i read the article, it doesnt apear to be an original LG battery...did u ever thought that batteries are not all about XXXXmAh? More is not always better
Think of cars... an american car(ex Ford Mustang) has an 4000cm3 engine producing 200Hp . Subaru has an 2400cm3 engine producing 300hp
But i could be wrong
Cheers !
You can try wiping battery stats
How do I go about wiping the battery stats? I'm using the stock rom BTW
You need a custom recovery (root your phone first)
You can gohere if you are unfamiliar with these terms
You can do it without custom recovery if you are rooted. Use either Battery Calibration app or Root Toolbox app. Both available in the market.

ye market has a few tools to calibrate your battery for you
calibrated
So I've rooted and calibrated the battery... but it seems that it hasn't changed anything. It is weird that an extended battery twice the size of the original lasts exactly as long (or less) than the original battery
Charge your battery to full, 100%, then wipe battery stats, and allow your battery to DIE. Then your problem should be fixed. i went through the same problem, i bought a special battery with better battery life and my Optimus t, running at 806/480 on smartass governor can run for about 4 days without dying, and thats with constant use

Can you post a link to where you've got this battery from?
Thanks.

mah DOES matter!
Battery life is dictated by the mah and how you use your phone. It sounds like the battery you received is defective which happens when you buy them from sites like ebay or amazon. Is there a return policy or warranty on the battery? You should definitely get more talk time and standby time with an extended battery.
It is a common misconception that you have to let the battery drain all the way. These are li-ion batteries which prefer a shallow discharge. Meaning, they prefer to be charged when they are at about 25% capacity.
Best of luck to you!

So true. The closer they remain to fully charged the longer they last.

[Q] 1590mah?

I'm wondering if my battery is defective or battery monitor is reporting the wrong mah of the battery. Battery Monitor is reporting 1590mah.
Thanks in advance.

1620mAh is the rating printed on the back of your battery, 1590 is probably a calculated value from what the App is probing, which is why it's a bit off.
Calculated values from kernel data may be a little off from printed ratings. It's < 2% off.
Battery Monitor Widget has reported everything from 334mAh to 4200mAh. It is an estimation.
Thanks for the clarification. I was still not satisfied with the battery life, So I went into verizon last night. The guy there tested the battery and said it was bad and ordered me a new battery. I'm skeptical on that the battery is bad. He told me the voltage was measuring 4.2v. The battery was charged about 71% and that time. Does that indicate the battery is bad or can the battery voltage vary from the 3.7-3.8v recommended voltage at times?

Why my battery drains so fast after I charge it to 100%?
Battery lowers very fast even when screen is off with no wakelock.

are your battery temperature is hot or not if isn't try to calibrate you batre with app on google market.
Had same problem after updating chrome, try uninstalling update from chrome.

It was definively not hot, 16 degree celsius. I don't think battery is not calibrated because I never changed rom.

Are you sure? I don't see a wekelock from chome, I neither see it in the battery stats.

battery percent is off!!

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.

doing it constantly is bad, once will not effect it.

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.

Ummm I said if you want to reset you stats not actually calibrate your battery. That app to clear stats is called Battery Calibrator. Never did i say calibrate battery

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.
Just let the phone die, it works , and its easy

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%.

Is it ok to fully discharge the battery down to 0%?

of course in most cases I will not do this trick but for battery recalibration since my phone battery indicator is totally a joke
I wanna give it a shot just once but I am worried because somebody says it will harm the battery life or even worse, let it dead(neither turned on nor charged). and many people also swear by completely discharging the battery all the way down and recharge it to 100% from time to time to reset the battery stat and have it work as it used to
so these two claims are contradictory each other so one of them is wrong.
please point out the right way for me. thanks
it likely won't kill the battery if it happens once (or occasionally), but i don't think it is recommended to do this regularly.
battery indicators are never perfect.
First of all, completely draining your battery could damage your phone and would reduce your battery lifespan. I recommend you to stop using the phone when the battery drops to 5-15%.
And battery calibration is 100% myth. Battery calibration just removes batterystats.bin and re-generate a new one. Android does the same once our device is fully charged.

well you're true but not all about the battery calibration,there another method which work and not a myth.the method is by charging upto the devices's limit voltage it can hold,you may have seen about "please charge your device 10 minutes more" its actually calibrating the phone's battery.but dont too overcharge it,it may get damaged,so be careful.

You mean trickle charging? It's for stabilize battery's voltage.
