[Q] battery drops as soon as i unplug

I just got my gs3 2 weeks ago. Since last week, whenever i unplug it from a night of charging, the battery immediately drops to 98%. I had rooted my phone, but i restored it to like out of the box this past weekend. Is this a known bug?
Thanks.

I don't think the batteries charge past 98% as a fail safe mechanism.

So the 100% is a lie?
also, what's odd is that if i unplug it initially, it drops to 98%. if i plug it back in for a few minutes and then unplug it again, it's up at 100 and seems to drain relatively normally.

The battery life on this phone is a bit of a mystery..I have had mine replaced due to just horrible batt life. It would drop 10% with about 10 mins of browsing. The replacement has been marginally better. I have no idea how people are getting 4 hrs screen on time with 20% left. I just flashed the MIUI JB4.1 Rom and its still not any better.

A common problem with the battery life is an error with account synching. Every few phones will have this issue, and it is easily fixed with a factory reset. Basically the phone will try every 3 seconds or so to synch your accounts only to fail, and try again. Causes the phone to drain in less than a half hour.

I retract my previous statement, I obviously don't know how to read.
Still, doesn't hurt to check. Go into your settings and check your accounts. If any of them have a red error symbol when you click on them then you may be having this issue.

It's possible. I got pretty close to that yesterday but that's being connected to wifi all day at work and at home and no videos. It's possible doing very minimalist tasks.

Imo, battery life on this out any around phone is not a mystery. Auto sync, auto bright, auto rotate, anything "auto" will cause more battery to be used. I can also tell you that simply hitting the home button to leave an app, instead of using the back button, will cause more battery drain. Wifi uses less battery than mobile data. Bluetooth will also cause a slightly higher battery drain. Email, or any app, set to push will devour a battery. Leaving apps open when locking the phone will cause slightly higher battery drain. Leaving wifi turned on when not connected to wifi will also cause a drain.
I know a lot of that is what people consider a smartphone to be used for. But with a little tweaking, most can get their battery life better. I personally leave auto everything off, screen timeout 1 minute, screen bright 25%, wifi/bt on only when in use, email set to poll when i open the app. I think you get the idea.

Screen timeout means nothing. Just put your phone to sleep...

Yes the 100% is a lie. Most phone manufactures only allow the phone to charge to 96%-98%. This gives the life of the batteries longevity. When I had the galaxy nexus developers would add 100% charge into their kernels so those who wanted to fully charge their device could...
Also if you look at your phone right after you take it off the charger it will say 98% but if you let the phone sit it goes back up to 100%. Don't know why though. I am no dev just my observations.

Battery Drain Problem

So I bought my ATT GS3 out in Los Angeles this summer and then I returned to New Jersey to find that I have horrible battery life. It was not right away so this could be completely unrelated. As of right now my phone is at 75% and I let it drain while i was sleeping for 10.5 hours. I have tried several different roms which are usually good the first two days and then after that the battery life is bad again. I thought it may be some application I have installed so I removed a few of the ones I remembered downloading since I got back to NJ. I also updated to the latest radio ending in H9 because I was two behind when I checked. I have attached some battery information below. Any help anyone could provide would be great. I have tried Juice Defender which did save some battery life but it also caused a problem where I couldn't use the internet for 10 seconds after I wake the phone.

U need a Rom with cell standby fix
Sent from my SAMSUNG-SGH-I747 using xda app-developers app

I thought the cell standby problem only effected the international GS3? If the cell standby fix was the problem then I shouldn't actually be draining that low right? Something must be draining the battery then. Google maps is probably draining the battery but how do I stop that from happening?

No its not just international and it is cell standby using almost 10% battery

try Triune ii or Black jelly 0.7 i tried them both on my s3 these both hav good battery backup..

Ariel 2.10 fixes everything!

I just installed the standby fix and im going to test that and see if it helps. If that doesn't work I'll try the other roms everyone has suggested. Will take a little while to make sure whats good and whats not though. Thanks for the advice.

Just another observation. Battery tends to drain faster if you leave it in your pocket. If you flash a rom, you might have to calibrate the battery stats. I only lose 1% every 2 hours overnight if I leave it on a cold surface.
Sent from my SAMSUNG-SGH-I747 using xda premium

So I have tried a few different roms and I'm still not happy with the battery life. I calibrate the battery after every rom installed and I usually keep that rom for atleast 2 days to test it. Right now I'm on AOKP. If the phone is on standby whats the general %/hr? When I go to sleep my phone drops from 92%-75% for about 10-11 hours (on desk at temp 60F). By Apocalypse487's response I should only see a drop of 5-6 % over night when I see 17%. Am I supposed to me losing this much battery life over night? To me I feel like I barely use my phone. Today wasn't too bad with 1 hr with screen on and about 1 hr in calls. I made it about 1 day 1 hour 36min on battery. My phone was sleeping for about 23.5 hours. Is this the typical battery life or is something wrong with mine? Tonight I'm going to try juicedefender and see if that helps.

I'm using ParanoidAndroid based off of CM10. Version 2.16 of PA gave me the best battery life. Try that. Certain Roms have better battery management, but that probably depends on the kernel. PA uses stock.
Sent from my SAMSUNG-SGH-I747 using xda premium

I'll give ParanoidAndroid a try and see what that does. So Juicedefender ended up making it so I only lost 1% over 9 hours. Thats pretty good. Way better than I wanted. So what could be draining the power over night. Is it because my data is on all the time but shut off when using Juicedefender?

I use Trinue 2, and I use an app called Go Power Master.
In GPM you can setup options that will turn off mobile data/gps/wifi when the screen is turned off, will automatically turn them back on when the screen is back on.
Those things little things I find can make a big difference for the battery to last throughout the day.

It's as Sianspheric says, common things like gps, data, and wifi uses power. I just started using Juicedefender since my friend told me it helps. Also download battery calibration. It's a root only app. Don't let your device discharge completely. It's bad for Lithium Ion batteries. That will clear out any bad data from Samsung.

How can you troubleshoot certain parts of your phone?

Hi All,
So recently I have been having problems with my battery life. It's not lasting as long as it should. However, I do not know whether or not its my data cable, the device that plugs into the wall, my battery, or the charging port in my phone.
I got my phone from best buy, but it was more than 30 days ago, and I have no insurance on it, so I cannot get a replacement without sending it away for at least $100.
Any tips?

Well what battery life are you getting? Get into the Phone settings and then battery settings and post a snapshot of the graph here. Additionally you can also install Batterystat it will give you a full analysis of what's using up your battery power.

I think I may have narrowed it down to the battery itself? I have some battery apps that tell me the health is "good," but what does that really mean? My charging cable is iffy, because sometimes it works perfectly, charging to 100 just fine. However, other times it charges 20 percent in 9 hours. When I used my friend's Note II charger, it worked perfectly every-time. But the fact of the matter is, when my phone does charge to 100 from my cable, I still get not the best battery life, which leads me to believe it's my battery's fault. I am going to test out charging my phone to 100% with my friend's cable tonight, and see what happens tomorrow. I will also get batterystat and report back.
Also, this may be important. When I first got my phone, battery life was AMAZING, really quite astounding. It's just kind of dropped down, like a slope. Not a sudden, dramatic drop, but incrementally.
As for the battery info below, here is what went on today. I unplugged my phone from 100% at around 7am. It is now 6pm. Today, my phone was barely used, just sitting in my pocket with wi-fi on. When I did use it, I sent two very quick emails, played scramble with friends for about 45 minutes total, took a few photos, listened to music from the music player for about 15 minutes, and that is really all I did. I feel that my percentage should be much higher than what it is listed as.

Here's mine as you can see I'm getting almost twice your battery life. I have a few apps that i use everyday which are basically whatsapp, xda, chrome. I don't have many apps that would wake the phone constantly and if there is then I disable them from starting up when the phone is not in use. The best tool you can use for something like this would be rom toolbox pro. It's multiple system tools in one and it works great. I'm currently on Omega V10 with perseus kernel. Also I don't connect to wifi much and network here is weak and on 2G but even though I still get this battery life. In areas with good signal I get more battery life. Also I've dropped my phone twice with impact points on the corner, and just minor scuffs but that didn't effect the phones performance or battery life so I doubt it has affected yours.

Also I've overclocked, my processor to 1.8ghz and undervolted between - 50 and -100. So i get minimal power wastage from heat build up. Also you can set a black wall paper with a dark theme.

Unfortunately, I am not rooted, and haven't planned on doing so ever. Is there anything else I can do to fix my problem? I did download batterystats, and am waiting a few days though to see what it tells me.
Also, I used a different charger just to see what would happen today, and even though its been off the charger for 2 hours, it's already down to 94 percent. So I am thinking that there is either something wrong with the battery, the charging port, or could there be a bug in the phone's software?
I am thinking of getting a new battery, and seeing if that fixes my problem. I'm just so irritated because battery life used to be amazing, and I don't know what happened.

Maybe try a factory reset. Maybe something else has been using your battery.

That's what I was thinking. I will probably do that and report back, before going out and buying a battery or something. Is it possible that, although not reported in the battery info, that an app could be rogue or something or taking up battery? I don't want to do a factory reset and redownload a bad app.

Update: I tried a factory reset. It seems to either be worse or just the same. It's been an hour and has dropped to 97 percent, but I have made a couple of phone calls. But compared to before I did a factory reset, it dropped to 96 percent in two hours while not doing anything.

Keep your phone on charging over night.
Then let it drain to zero no matter what.
Do this 3 to 4 times and then
Leave it for charging overnight.
Then while it is already charging use battery calibration.

Quick Update:
I did another factory reset after I said the initial one didn't help. It looks like it may have helped, although I still have not gotten the battery life I used to have.
I found an application here called betterybatterystats, and have downloaded that. I will use my phone throughout today, and will post sceenshots.
If need be, I will take your advice about charging and draining and charging, and then do the battery calibration.

Here are my most reset battery stats. Screenshots are from the battery setting area, and betterbatterystats
Maybe I am just being paranoid and nothing is wrong? I can't make any sense out of these readings, but I hope someone else can.

first of all change you cable if you are having that kind of issues. Mine in my galaxy ace was having that problem, it was like connect/disconnect without any reason and it didnt charged my phone at all. I noticed it when it was too late, the continous on/off kill my battery. When I say kill i mean it just lasts 15 min in 3g with screen on and it happened to me in 2 official batteries.
good luck!

[Q] Short battery life

I've had my Galaxy W for just over a year. Whilst I was running the stock ROM I would more or less get a full day out of the battery. I upgraded rooted my device and installed the Cyanogen CM9 rc2 ROM. I don't recall any battery problems at first, but just over a week ago it started draining within five or six hours. This happened every day for a week.
Since then I have uninstaleld all apps (apart from Google Authenticator which I couldn't manage without), turned off wifi, bluetooth and everything else I could think of. Now I seem to be getting about 36 hours out of the battery... Although I think it goes from 35% down to 10% very, very quickly.
Leaving all data connections off and having no apps is okay in the short term, but is there a long term software solution?

Not immediately, but about a week later. Is it worth going through that process again?
Edit:
This is the app that I used:
https://play.google.com/store/apps/details?id=com.nema.batterycalibration&hl=en

Before I uninstalled any apps I downloaded and installed CPU Spy. Here are two screenshots taken with CPU spy.
I could reinstall it now without any other apps installed, if that will help?
I don't know enough about this, but I expected that the phone would spend a higher percentage of it's time in 'deep sleep' than that.

Interesting.. how about you check on the battery is it bloating or not?
For battery problem is either the phone calibrated wrong readings on the battery or the battery it self is the problem.
If you use your phone not too often but the deep sleep only reach 34% of the time then some apps is preventing the deep sleep, try to check what apps is that causes that with some battery stats app, try search it in xda or market

I've gone for Battery Stats Plus. I'll reenable wifi, bluetooth and 3G for a few days and see what happens. If that takes a toll on the battery I will post back with details from Battery Stats Plus.
I will also take the battery out later to inspect it.
Update:
My battery had 15-20% remaining and I turned it off, and tried to turn it back on. It now thinks that it does not have enough power to boot the phone. I don't know if that new information is helpful or not.

With 15 - 20% it should have boot, because it still have juice left. What about your battery physics? Is it bloating or just normal?
Sent From Viperized Sensation Z715e

Took the battery out this morning for a proper look. There's definitely some bloating. Time to get looking for a replacement battery?
Could there be two issues here? As from the screenshots I posted the phone doesn't seem to have spent a lot of time in deep sleep.

I was just watching a YouTube video, with about 70% battery. The phone turned off, and when I've turned it back on it's gone down to 2%.
Could this be down to an improperly calibrated battery, or is it purely down to the physical damage/bloating to the battery?

I'm going to install Battery Calibration by Nema from Google Play. I'll see how I get on with that.
I'm going to order a replacement battery this week. I'm looking for a direct replacement, with an official Samsung battery. I have posted here in the Accessories forum. I hope that was the right place to put it.

After I install the CM10 alpha 6 conform to the first post, the battery life of my cellphone has been drained very fast - 21% about 6 hours and half.
Can anyone help me, please? I already did the battery calibration and I can't see effects. I'm wondering if is better install CM 9 or just go back to the android 2.3.6 factory version of my cellphone.

Your battery is bloated? Then you *must* replace it. Period.
A damaged battery is the root cause of myriads of problems. Until that battery is replaced, you _will_ experience all kinds of annoyances, no matter what ROM/Kernel you're using, including inexplicable battery drain.

[Q] New Battery - Better Android System Usage?

I have an AT&T Samsung Galaxy Note 4 running Lollipop. I've noticed I have been having fairly poor battery life over the last few days with Android System taking up the most usage. I purchased a spare battery for my Note 4 yesterday and I have been using the new battery with my phone. My android system usage is significantly lower with the new battery. Does this mean the older battery is defective? Or is it something else with the phone? Has anyone experience the same circumstances?
And yes, I have a SD card installed and I have factory reset my phone and wipe the cache after I installed Lollipop.

If I were you, I'd use the new battery a few days before jumping to conclusions. The Android System usage may start up again. Knock on wood that it doesn't.

Thanks for the reply. Hopefully it won't start up again. I just feel it's weird because a new battery shouldn't affect what is using the battery but rather how long the battery lasts. Isn't that right?

I think so. I mean, the only thing I could think of that might reduce ASystem with a new battery would be if the new battery didn't have NFC. Then MAYBE ASystem will go down just because the system wouldn't be detecting the NFC chip. But even then, I wouldn't expect a huge drop in %usage.
If the old battery was defective, I also wouldn't expect ASystem to run high. If the CPU were bad though, then it definitely would because the cpu may not enter deep sleep, so the phone is always technically on. (I had the happen with my old phone. Had to get it warranty replaced).
Just keep an eye on it for a few days to see if things continue to stay good.
Btw, what battery? OEM? Third party? Large capacity (like a 6400mAh battery)?

The new battery is just OEM. and thanks for your input.

So...with the new battery about 10 hours of run time and 4.5 hours of screen time (mostly YouTube). I am at 8% battery life? Is this normal?
Also here's my setup
- Bluetooth off.
- Location On - Power Saving Mode
- WiFi on and connected, look for WiFi network is On. Always connected to WiFI is on.
- YouTube @ 15% of Battery and Screen / Android System both taking up 14%.
- Screen Brightness on Auto
Is this normal or should I be getting battery life out of my phone?

I think many people report 4.5-5 hours of constant screen on time, so I think your getting normal battery life.
I usually get about 1-2 hrs screen on time, but my phone is in standby for tge rest of the time. I usually then get a day and a half of battery life (or 2 days).
