Not sure why, but I restarted my phone and it went from 50% down to 5 % power? Had it on the charger all night and it was still at 5%?? Took it off the charger for a few hours and im still at 5%. Tried wiping stats and had no luck? Any Help??

Drain all battery and charge it from zero. Let it be fully charged before starting it. If you run CWM you can wipe battery state.
Your question is in wrong section in the forum. Try starting the thread in General.
Cheers
+1 this -- and some additional detail...
Wiping battery stats does NOT improve actual battery life. If done properly, and coupled with a calibration cycle, it can increase the accuracy with which your battery reports its current charge. Ideal process is as follows..
Charge to 100%
Reboot into CWM
wipe battery stats under" advanced"
Reboot
Charge back to 100%
Let it DIE (go to 0%) from normal use, DO NOT charge it during the cycle
Re-charge to 100% and you're all recalibrated.
From the sound of it, don't be surprised if your phone sits at 5% for hours. After the calibration, your battery history should be a relatively smooth, downward sloping curve.

Check Settings>Battery Information>Battery Usage and see if a process named RILD is using a high percentage of your battery usage. That process - a very necessary Motorola radio daemon - is wreaking some havoc by causing very rapid battery discharge and also preventing normal charging.
No solution for you but thought I would let you know before you try too many different "solutions" needlessly.
Thanks!

Hi Guys,
I know there's been a few threads on this, but a lot of them don't really answer what I'm about to ask.
I've noticed lately that my battery has been losing about 10% in the first half an hour, then goes down quite slowly which makes me think I need to wipe the battery stats. However a lot of people keep saying 'wipe battery stats' then fully drain, which seems like a ridiculous idea knowing what we know about how badly batteries react to full discharges (on a bad day you can actually knacker the battery), so what I'm asking is can I just wipe the battery stats at 100% without discharging. The user manual never said about fully discharging my phone when I first got it so why would I need to do it now? Also, this concept of bump charging, how would I do it on a Galaxy I9000
Thanks very much!
Breaking you battery through a full discharge? Never heard of that.

again though, a full discharge, is that wise?
You need to calibrate your battery. There is an app in the market..just search "battery calibration". Charge your phone to 100% then use the app to wipe the stats. Let your phone discharge. Full discharge is not necessary. Discharge to 1% then charge it back up to 100%. Good to go. If you don't want to use the app, you can wipe your battery stats in recovery which accomplishes the same thing.
When you drain your battery, your phone will not just stop working at some point, it will shut down your phone in an orderly fashion before you battery is fully depleted.
When I drain my battery and my phone shuts down because of it, I can still switch it on again and it will work for a minute or so after it has fully started before it will switch off again.
Could I not just wipe the stats and not fully discharge? Or does that achieve nothing. I'm pretty certain it's these battery stats. Today, it went down to 84% in seconds. I've noticed if I plug it in, it charges full, unplug, then plug in again, it starts at about 91% and does the rest. Sound like a battery stats issue?

When you charge, you phone says "charged" as soon as it hits 90%. Check the about-menu in settings (or in my case at least, the lock screen while plugged in) to see at what percentage you really are when your phone says it's charged.

Oh right I didn't realize that. I'll try it. I've just unplugged it and it immediately said 98% so I plugged back in. This time when I pull, I'm going to wipe the battery stats. I don't really want to discharge fully, because even at 1% it's not great for it. If anyone can state categorically that I shouldn't, tell me now please haha
I have had Transformer Prime for over a month. its rooted and never gave any battery issue. i have installed Battery Booster app to monitor battery percentage and temperature and also to be notified when battery is fully charged so i dont over charge it and damage the battery.
recently my prime shuts down with 30% battery still remaining. i have to charge it to get it back on. Once i charge it for 5 - 10 min it turns on showing 34-35 % battery life. ( Battery Percentage checked with Both Battery Booster app and built in Device settings )
Kindly Help.
Wipe the battery stats, it has the "dead" state at 30%.
Wipe the stats, run a full cycle or two and it should be good to go.

I have already done that , and now have my fingers crossed , will update once i reach 30% or Below.
Ok . wiped the battery stats , charged it to 100 % and no problem faced after that. took 5-6 pics with flash on at 1% battery remaining, still didn't die.
Good to hear!
You might want to change the thread title by adding solved at the beginning or end.
If you're not sure how to, if you edit your first post and go into advanced mode, you can then change the title.
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
I had wiped battery stats with clockwork recovery since 2 months
I’m facing problem with battery calibration, I tried many application to calibrate the battery but till now the battery will not charge to 100% even it is connected to the charger for 10 hours
After charging it for around 10 hours it appears 62% and when I reboot the phone it is coming 97% and after 10 minutes it is appears 100%
Is there any idea how to calibrate the battery and fix that problem?
The method I use would be as follows:-
1) Discharge your battery till your phone turns off.
2) Charge it for about 6 hours.
3) Go into Clockwork Recovery to clear battery stats.
Your battery should be close to what you expect it to be.

Contrary to what many people seem to believe, your battery stats do NOT in any way influence the displayed battery percentage indicated by the phone. Never "calibrate" your battery by wiping battery stats.
The problem the OP is experiencing is an indication of a hardware problem with either the phone or (more likely) the battery.
Are you using an OEM battery?

yes, I'm using the original HTC battery.
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.
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%.
