Samsung Galaxy S3 Charging Issues

[Neader]

Hey everyone,

First off, save your breath. I'm not one of those people who don't understand why their battery is dying when their brightness is all the way up and they're running every app possible.

For the last three days or so my phone's battery has been draining, except it isn't the batteries fault. Yes, I know this is a common issue, but I've tried a lot and nothing is working.

Right now I am losing 1% of battery every 4 minutes, and this is when my phone is on standby the whole time and nothing is on, data isn't off, I'm not connected to wifi, I don't have Facebook on, literally all my apps are off. So my battery life for my phone, without even using it, is roughly 6 hours when it used to be around 20 or so.

I've tried everything, if you notice I said it's been doing this for 3 days. I purposely held off posting to do research and see if I could fix it, no dice.

Factory reset? Nothing

JuiceDefender (free)? No dice.

WakeLock Detector? Isn't telling me anything.

Hell, I even went to Verizon, and since it's a replacement phone I got a month ago through Asurion they basically told me to **** off, it's not their problem since they didn't give me the phone.

I still have the battery from my old phone and even when I use this battery it's still draining.

So I'm guessing it has to be some software update or some app that's running, but I don't know what! There hasn't been any app I've recently downloaded and if there is, the factory reset should have taken care of it.

Here's a picture of my WakeLock and battery usage.





So, does anyone know what the hell is going on?

Did you try rebooting into Recovery mode and clearing the cache?
Is your Verizon phone running 4.1.2 (the MF1 build)?
Is your phone rooted?
After the Factory Reset did you just reload all of your apps?

I have no idea, how do I figure that stuff out?

 

[GSDer]

Build information - from any Home screen, press the Menu button, select Settings -> About phone:

To reset the system cache:
- shut the phone down completely
- press and hold the Volume Up and Home and Power buttons simultaneously and release them all when you see the splash screen
- use the Volume rocker to navigate the menu that's shown; the Power button selects
If your phone was rooted you'd know it

I have done all of these except for rooting.

Still nothing...

First off, lose the battery savers. They really don't help all that much, and often make things worse. That's not your problem here, though. A couple of questions about the battery screen you posted. Was the phone charged to 100% when that 4h 31m cycle began? It looks like your phone rebooted a couple of times (the vertical gaps in the chart). I've noticed that a reboot can throw the time shown way off. Are you sure it was only 4 1/2 hours since it came off the charger with a full charge?

If Android System is the primary thing draining battery, you probably have a runaway process. This thread may help you diagnose it: http://forums.androidcentral.com/sa...android-system-eating-your-battery-check.html

Even if it's not the exact process I discovered was my problem, the troubleshooting techniques should help you figure it out. Let me know if you have any questions about what I did.

The full charge was roughly 6 hours before that, but during some of that time the phone was off, probably close to only being on for 4 hours.

I'm confused about information from the other thread. Mainly this,

"A reboot stopped the run away process, but a week later it happened again, so I started doing some research. I found some threads showing this killing the battery in some 3rd party ROMs, and recommendations to rename it as QOSMGR.bak, but not much more info than that. One poster on XDA says QOSMGRs don't accomplish much normal devices, and are more useful on routers. I'm rooted, btw, but on a completely stock ROM. QoS Managers, if you don't know, are processes designed to prioritize network traffic, based on a sometimes complicated set of unexplained rules and magic. With not much info available, I decided to rename it and see if I could detect any issues. "

Can you go into more detail with this?

 

[meyerweb#CB]

That detail is probably irrelevant to identifying the problem. QOSMGR is an internal Android system process that apparently can run out of control. When it does, it sucks cpu cycles and battery. Exactly what it does, and why, doesn't really matter. What matters is finding out if that process, or another one, is causing your battery drain.

I wrote that to provide background info for anyone who was interested, but may have just confused the issue. You don't need to understand what QOSMGR does to figure out if that's your problem.

I downloaded Watch Dog and it didn't tell me anything.

Now what?

 

[meyerweb#CB]

Try System Panel. Or check Show CPU usage in developer settings, and see if one particular process is always at or near the top of the list.

Have you rebooted the phone since this rapid drain began?

 

[Neader]

CPU usage just shows com.android.systemuj

and yes I have rebooted it.

According to system panel CPU is at like 4% when I don't do anything but when I just scroll through the apps it goes up to nearly 50%, just by touching the screen.

 

[meyerweb#CB]

What System Panel is showing is normal. CPU use will spike briefly whenever you're doing any action; it's when some process or program keeps running and using a lot of cpu when it shouldn't be that causes problems.

In System Panel, tap on menu, then settings, and make sure there's a check mark next to System Processes. Then go back to the main screen and scroll down until you see internal system processes. Do any of them seem to be using a lot of cpu compared to the others? If that check box was unchecked, it may not show this for a while.
