Screen/Network Bug

Hey Everyone,
I've had this weird bug on my Samsung Epic 4g Touch.
What happens is when im using my phone the screen will suddenly start to flicker and then id lose my service and then my phone would just shut down. After it shuts down if I try to reboot it, it will reboot and then it will shut down again almost immediately after using it. This bug isnt action specific and occurs at really strange times, I can get it to stop by waiting about 20 minutes or plugging it into a charger.H owever this ONLY HAPPENS WHEN IM RUNNING ON BATTERY it will not happen when im plugged into a charger. I know this isnt ROM specific because it has happened on multiple roms :/. SOMEONE PLEASE HELP ME!!!
Info:
Samsung Epic 4g Touch
Current Rom: AOKP Milestone 6 no overclock

I'd replace the battery and/or check the phone without sd card.

Defective phone if it happens on multiple ROMs....take it back if the battery change doesn't work. You may have a refurbished phone that isn't up to par.
Sent from my SPH-D710 using xda app-developers app

But I know it isn't refurbished....I got it the day it came out..what I might just do is wait for another nice android to come out and then trade this one in.
If I'm going to return this one, do I have to restore stock firmware?
Sent from my SPH-D710 using xda premium

Do you use battery monitor widget or use a battery besides the stock battery? I had this problem. I use three batteries all with different mah and I would use battery monitor widget to calibrate them. Once I have all my profiles set up by entering each batteries supposedly mah I would have this same problem. I was finally able to fix it a few days ago (after a few months of torture) by using the estimated value on the calibration screen in battery monitor widget. For some reason the app would estimate my batteries at a higher level or lower level than the battery claims. Hope that helps in any way..

(Q)How long does it take you to charge phone?

How long does it usually take to charge your s3 fully? I ask because mine has always charged very fast but lately its taking sooo long to charge and I dont know why..what do you guys think?
Sent from my SGH-T999 using xda app-developers app

with the standard charger came with S3, usually took around 2h30 to fully charge.

Mine used to charge super fast but now its taking soooo long.. its takin me an unusually long amount of time.. any body know what could be up ?
Sent from my SGH-T999 using xda app-developers app

I can't really tell you a time exact but not that long. Last night I was at 50% plugged it in and charged completely in bout 45 - 1hr. I usually don't touch it tho.

Takes me a about 2hrs. With the charging accessories that came with my phone. Are you using the original charging accessories?

Rogue app.

Yes everything I use is official samsung came outta the box.. I had been flashin quite a few roms then went back to complete stock lj4 and it just seems like its taking way too long to charge.. ive never noticed this problem infact I was always alarmed at how fast it would charge
Sent from my SGH-T999 using xda app-developers app

With the phone turned off, it takes mine about 2 hours to charge.

When you flashed this last rom did you wipe data/factory reset?
Sent from my SGH-T999 using xda app-developers app

I have a Q: My rom (SlimRom2.9.0) has an option for Quick Charge mode, where it will charge faster but you loose USB connectivity functionality (for connecting to a computer).
Will the SGS3 also take advantage of a higher output (2.1a) USB charger, ala iPad chargers? Does the circuitry inside detect and is smart enough to adapt?

Look at the battery stats and see if something is hogging it. Get something like battery drain analyzer to see the percentage you're charging at.

You guys think it has anything to do with the stock lj4 kernel? My battery life kicks ass 4 hours screen on with 17 + hours of battery life.. still charging is slower than usual. Hmmmm

I would try to drain the battery all the way down, then with the phone off, recharge it back to 100%.
After that see if there's any improvement.

Been on the charger for 4 hours ive been using it and booting to recovery here and there and from 8% im still only on 85%.. so damn strange. Tonight im going to borrow my buddys charger and see if it improves.. but this sucks

Mine takes about 2 hours from 15% sometimes I'll be playing a sandbox game and it will take much longer. Just don't unplug it when you plug it in.

Could it be a faulty battery?
Sent from my SGH-T999 using xda app-developers app

Like most others on this post, my GS3 will take roughly 2 hours to charge.
Depends where I am charging from, usually I end my day with around 20-30% battery life still.

It could be. But to be sure id do the full cycle I mentioned before, and even consider flashing back to stock! Just for testing. You can always nandroid and go back if you like. Though a fresh rom flash may be better.

I use the charger from my 10.1 tab. I believe it runs at 5 amps. Definitely charges faster although I've never timed it by how much. If I charge it on the wall charger that came with my chinese batteries, it takes over 9 hours sometimes. Yet the chinese batteries only ever charge up to 91% on it's own charger, I have to charge the rest once I put it in the phone. Weird.

Sloww charging!

OK guys not sure whats been going on but i had around 8% left its been 4hrs or 5 and its only up to 78% thats a bit crazy if you ask me. Im running a custom Rom 4.2.1 i believe i feel like going back to stock...

Where did you get 4.2.1? The kernel in something that for off from what is in the usual development channels may have an impact on charging. I'd stick with 4.1.1 or 4.1.2 for current kernels.

I had this problem also when I had the note 2 for about a month...happened twice only though, not every time. I ended up returning that phone because the mic kept cutting out. I haven't had this problem on a new note 2 yet (been about 3 weeks). So there might be something wrong with the device, i don't know.

When you plug in the charger, double check that it says "AC Charging." I have plugged mine in and gotten mixed results:
1. AC charging
2. USB charging
3. Nothing
If I get #3, I restart and usually get #1.
You can also install a battery monitor app and check the log to see how much charge you are getting.

Was your phone just charging or were you doing stuff?
More importantly, what does it say for mA in the log.?
Can you post a screenshot of your log?
sent from my phabulous phablet using xda premium

If you were flashing a new rom or any big file. You should never flash below 50% percent. I did this the other day and it was just charging so so slow. So what I did was turned it off and let it charge. While that was happening I guess when it hits a certain percentage it automatically turns on. It turned back on and it was charging just fine. And also when your on the phone while charging the percent goes down for me as well.

I dont think your charger likes you ^_^ Jokes aside, is your charger going through an extension or straight off the wall? Maybe try a new extension or a different wall socket.

Something is wrong there. Easy candidates are:
Your battery
your charger
your cable
Do you have any way to swap out any of the above to see what it may be?

Random input.....
I just happened to be charging my phone while browsing the forum yesterday when I came across this thread. I'm not having any issues I was just killing time and being lazy..
It made me check my battery and I noticed it seemed to be charging kinda slow. (I had been plugged in a while and hadn't gone up much) I checked battery in settings and it said charging USB. I was plugged into the wall outlet. Strange indeed!
I unplugged the usb from the phone then plugged it back in and it switched to AC. It definitely started charging faster after that.
I never would have thought to check this so I'm glad I was snooping around.
Just figured I'd share my experience.

I've had the same problem with slow charging every once in a while. I think it has more to do with the kernel and/or rom. I had times when it took overnight for the phone to charge. Now it charges full in about 2-3 hours.

The latest version implemented fast charge something to try.
If you just flashed it you will go through your battery considerably faster until you do a full charge.
Besides battery usage is dependant on each phone and individual user.

What sort of battery drain are you seeing? Curious as I used to use Task's ROM as well and never did get the same battery life as others were reporting...I know everyone uses their phones differently and have different app, but even with limited apps and usage, never really got great battery life.

Ok so far i have left the wifi and internet off and the battery is hardly at 80% since 8am. Huge difference!
But as soon as I turn it on either 4g or wifi it drains very quick.

4G is one of the known biggest battery drainers. This isn't just for my rom. It's for all roms on all devices. Battery life is also users dependent. There are so many variables like location, apps, settings, the way you use your phone, ect... the list can go on and on. With that said. I always get around 22-25 hours and 3-4 hours screen on time on a single charge. That can vary depending upon my usage.

3 reasons: You either have Google Now setup, You sync too much stuff and/or you have location access/GPS turned on.
And as Task mentioned, 4G is a big battery drain. If you feel it's too high, drop to 3G/H while you don't need high internet speed.

Ok I checked and I made sure to always kill all running apps.
Definitely the wifi and the 4g drain battery to quick, very quick.
But what really pisses me more than all is how slow it takes to recharge...
I tried FAST CHARGE but all that do is to charge from usb ports like if it was your wall electricity socket.
The only option i have left is the Kernel you guys keep suggesting.

Solved the problem at least for charging.
I bought an used Galaxy s3 and apparently the guy kept the original charger or lost it and the one I was using wasn't good at all.
So I had another charger of the HTC one x and this one works perfectly!
But still, now I need to find out why it drains battery so quick when I'm on wither 4g or wifi.
Does the Kernel do that much difference?
Well if that is a yes then I have a few questions:
Do I have to wipe my memory so I must do another back up?
Will this Kernel be compatible with Galaxy s3 i747?
Any step by step guide that I can do this easily without any warning or danger?
Link please?
Thanks.

All you need to do is read the OP of the kernel thread that you want to flash. That would be your step by step. 4G will always be a battery drainer. There's nothing you can do about it.

I also run task 650 but I don't believe that the slow charge is ROM related. My phone seems to take forever to charge since I upgraded to jb. I'm thinking there was an issue with my battery because my wife's gs3 charges much faster. Only way I was able to work around this was to charge while powered off. This happened on every ROM I have flashed in the last couple of months whether aosp or twiz.

Battery drops to zero during calls

I'm running CM9 and have had this problem with 2 different Samsung Epics...I'll be on a phone call with, say 38% battery and all of a sudden I'll hear a system beep and look at the phone and see it's dropped to 0%, shutting down the phone. I've had different modems installed and always had the same result. Just wondering if anyone can point me in the right direction.

Sounds like old batteries.

Yeah, it seems to me like it could have something to do with voltage or something, but I've been using about 4 or 5 different batteries with the same results.

Do you think it is as simple as that? I am pretty bad about popping the battery out when I change batteries without shutting down. I charge them in an external charger (and charge the one in the phone overnight in the phone). I'll give it a shot and start shutting down properly before putting a fresh battery in. Thanks for the tip.
