Hello all, new to the E4GT world from the OG evo and I loaded starburst 1.9 after formatting system and data, wiping cache and then dalvik cache in that order. I find though while I was loading all my old apps to the new rom that the battery percentage keeps dropping even when the usb is connected. I'm using the official samsung cable. Does this happen to anybody else? Thanks!

I've had this happen but only when I was overclocked and watching videos while connected via USB to my PC. If you're plugged into a wall Jack and this is happening there's probably something wrong. Also make sure you're using the adapter that came with your phone as different phones have different voltage/amperage and that can cause them to kill the battery. I've had to tell this to friends and even had one permanently damage their battery where it wouldn't take a charge because he was using an old charger.
USB connected to your PC just can't give enough juice for high end phones. That's why they charge slower than when plugged directly into the wall.
Thanks for the heads up, I normally work with the screen always on when connected to usb, but it appears to be charging normally now that it's attached straight to the wall. Still it's sad to see I can't overclock easily while on the PC
With many phones you can use up power faster than it can charge. Doing stuff like tethering over WiFi with both WiFi and Cellular radios running is a common scenario, but you can do it other ways too. If the phones charge too fast, they can overheat too, and they could have circuitry to disable charging in an attempt to reduce the temperature.

Yup. Running wifi tether with the screen on with an overclocked kernel is another scenario where this phone can't get enough juice from the USB port

Alright..... for some reason this is a very...VERY difficult thing to find an answer to despite me already knowing a lot about it...
So, I use my epicTouch to tether 4g to my laptop while at work. I have both usb 2.0 and 3.0 ports on my laptop. Over time though, the battery drains, rather than charging. Now I know that it is because the phone won't draw full power when connects to USB but that you can trick the phone into thinking the USB is a wall outlet unit and that it will pull the full amount of power that it can....but, how do you get it to do that? I found a few apps on the market and such but they seem to rely on a certain type of kernel.
So my end result is, I want my phone to charge faster....or rather, charge at all versus losing power, while tethering.
I guess I would like to know if it needs a certain kernel, which kernel that would be, which ROM I could use it with, which app to use.....but all I really need is a solution.
Right now I'm running CM9 and the kernel that came with that.
Thanks!
I remember seeing a kernel tweak option that allows "fast charging" in AOKP Build 37.... but I forget if data can transfer while its turned on.... if your interested look into it on this thread.

Thanks. Last time I used AOKP I had a few issues with it and I'm really liking cm9. I'll give it a look though!
I don't know about aokp, but stock based roms have a toggle for USB charging somewhere in settings.

Update.... I tried using usb 3.0 to tether a while back but it wasn't working. 2.0 worked though so i used that. Turns out i just didn't have my drivers installed, once they were up and running though, the phone actually charges instead of discharging slowly, and it may be just placebo, but I feel like the data speeds are a bit snappier too.
Still though, wouldn't mind knowing if someone has an easy way to enable faster charging.... I also know a motherboard I used to have had a setting to make a usb port be used for fast charging... So maybe the trick would be on the pc end and not the phone? It seems like the phone regulates the power is consumes based on what the port tells it.... So maybe either end, pc or phone, would solve it. Thanks again!

Does foxfi 4g hotspot work with ICS or CM9 yet? I rolled back to EL29 and downloaded the latest foxfi it works just fine. Plug phone into wall outlet then fire it up. I know its not the ideal solution but I got tired of ICS stuff that sort of works.
edit: I also have this wire for en external hard drive that plugs into 2 usb ports. I assume that means it will pull power from both ports. Never tried with phone though
Just FYI, USB 3.0 and 2.0 will output the same amount of power if you plug the phone into either. The phone it self determines what power to draw, so finding a tweak for the phone is the only solution for your problem.

So then,
Recently I have had a lot of issues with my nexus. There has been on going issues related to the battery in terms of it saying its charging when its not, and not charging when it is.
yesterday the phone totally died, which wasn't ideal so I contacted Samsung and they said they need to send it away.
Now luckily I do have a extended battery for my phone which I have managed to get it working off and get it to charge which points at the old battery dying and needing to be replaced.
Issues which remain is the phone does not say its charging yet the battery is being charged. Is it possible to delete the System battery apk and re-install it and does anyone have a link to the apk. Or is it possible to re-calibrate battery settings somehow?
The phone also will not connect to the computer via any cable.
It seems as though the phone is being charged and the power is going through the phone, but there is no recognition in the USB bay of any kind, weather connected to a charger or a computer.
things done so far to solve issue:
Full wipe
Reverted to stock
Reverted back to different ROM's
Changed Kernel's
Ordered a New standard battery
Ordered a battery charger (not phone charging dock)
Wiggled the usb , changed usb cable's and chargers.
Fixed permissions
Delete battery stats
Full delvik cache wipe
This is becoming to be a serious problem with a otherwise amazing phone.
Any help would be fantastic.
Thanks,
J
I'm also having the same issue for a week or so. The phone says it's charging but it's not connected to any charger.
Lots of people are reporting the same problem. It's a hardware issue. You need to change the usb charging assembly.

Thanks for the heads up man , might give the USB port a little clean. Pain in the ass though pretty poor from Sammy and Google on that one :/

Hello guys.
My DHD's USB port seems to be dying. When I plug it in to charge via AC, it charges the phone, but only at half "speed", around 300-400mAs instead of 800-900 like it used to do before.
When I plug it into a USB port, it charges with the same speed, and it doesn't offer any USB connection option at all, no USB icon in the notification area, nothing happens on the laptop either.
When I manually set the USB connection type in settings to Mass Storage, the USB icon shows up in the notification area, the SD card is no more accessible from the phone, but again no USB connection dialog, nothing happens on the laptop, the phone only gets charged at the usual USB charge speed.
I was on Jellytime r30 when I noticed this first, since then I tried several ROMs, even reverted back to LeeDroid for a while, at the moment I'm on Sabsa 10.0. It's all the same, it doesn't seem to be ROM related. But strangely when I reboot my phone, USB connection works for the first time (charging speed is still half when on AC), after it it's the same again I described before.
Can it be related to my slowly dying battery? I have to charge it twice a day, sometimes its power just jumps up and down.
Thank you for all your help in advance!

Hmm.. I'd say its port.
Buy another battery and see what happens, cause it could also be the battery.
I'm about 40% convinced its the battery, and even if it isn't its a good idea to buy a new battery (cause of your battery life issue)
Thanks, I ordered a Mugen battery, we'll see, I keep my fingers crossed to the battery be the culprit.

Mugen batteries are good, highly recommended :thumbup: :good:
If it is the port there are replacement parts available on eBay
Also try to clean the port with a needle, there could be some lint accumulating there

Solved: just to let everyone else know who face similar issues. I received the new battery (Mugen 1500mA), and all the problems are gone, USB is working again, charging speed is back to normal.

Reboot to recovery, Clear caches, (Dalvik too) reboot phone, see if it works.
i had this issue when i bought a "lot" of cables from e-bay/amazon. Turned out they were "data only" cables and never provided power.

Interesting... I always buy my cables off Monoprice. They are cheap and they have a really good return/exchange policy.
yeah didn't change cables or anything... i'll try the clear cache and davik
It's most likely the cable,
It can't show 100% unless the voltage at the leads of the battery is 4.2-4.3V.
At the same time, 9% is around 3.6-3.65V.
Can a bad cable fool the phone into thinking that the voltage isn't what it really is?
What is the phone showing for the battery voltage when you unplug? There apps like System Panel (in Settings/Monitor) which can show voltage.
Stock charger or an older/cheap one?
Sent from my SPH-L710
stock charger - been working for 9 months. i cleared cache + davik, and now its taking forever to charge
I had this issue on stock touchwiz for Galaxy S (SCH-I500). Whenever the battery was fully charged, it would quit charging, say unplug battery, and would not update the battery % (always showed 100) until I unplugged the phone. Once unplugged, it would immediately drop to the actual %. When using TouchWiz, I had to use kernels with trickle charge to solve this.
I've had issues like this when I was using " Bargin " USB Cables. Learned my lesson after having multiple issues with file transfers, and charging.
Do you have any app which control battery? If yes uninstall it.

About a week ago, I flashed to the Beanstalk 4.2 JB rom. And found that while running the rom, I began suffering from real odd battery patterns.
I had two wall chargers and a USB cable to my computer, when I connected my phone to them, it would say that it was charging, but instead, it'd just drain the battery.
Using my 4.1 AOKP rom simply a few days ago, I never had a problem as weird as this. All my chargers worked on my phone, including the USB.
The only time I could charge my battery properly was to have to phone completely off.
So after a week, a few days ago, I flashed the SlimBean Rom in hopes I'd get a different experience from 4.2.
Now things got really weird. The phone would start repeatedly flashing that it was charging and not charging. Battery would still drain, what's worse is after calibration yesterday, I tried charging my phone while it was off. The battery during this charging process, said it was full. So I turned on the phone, and found my battery at 15%.
But this weird behavior isn't all the time, just now I plugged in my phone while on, using my wall charger. And right now it's acting fine. The question is, when and why is it doing something weird?
I'm not sure why this is happening. Everything was fine until 4.2 a week and a half ago, now my phone is acting like there isn't a consistent way to charge the battery, it's pretty much randomnly taking power and using it while it's connected to a charger.
Does anybody have similar problems with their phone after a flashing? Again, everything was fine when I was using 4.1.

Time for a new battery. Take it out and see if it spins. If it does, your battery is bad. If not, you may have a bad flash or rogue app; try clean flashing your 4.2 ROM and manually installing apps from the play store.

What do you mean by "see if it spins?" Do you mean spin it flat on a table?
Also, I have factory reset and flashed both roms each time. Is that a clean flashing?

yes, spin it on a flat surface. if it spins like a top, its bad. if it doesn't spin, its probably okay.
clean flash (for AOSP) means:
Reboot to recovery
Make a nandroid
Wipe data/Factory Reset
Wipe /cache
Advanced > Wipe /dalvik-cache
Flash ROM
Flash Gapps
Reboot.
I have a new related question:
Is it possible that flashing a rom could damage hardware? Like the battery or something else?
The battery sometimes will not recharge EVEN when the phone's turned off ever since I switched to 4.2. It's become a phone that is insanely unpredictable.
Battery doesn't spin, it's still fairly heavy. I'm a little worried something darker might be effecting my phone now.

Not a ROM issue. I recommend using triangle away to reset the binary counter, then Odin back to stock unrooted fl24 or gb27 and seek warranty replacement.

Same Problem
I am having the same problem with my phone. im running ReVolt JB 4.2.2 6/2/13 ...same weird flashing when connected to charger, battery only charges when its turned all the way off and plugged into a wall charger. Battery is still good doesn't spin...for me its only this rom that gives me trouble.
Everyone's has the 3.0 kernel on 4.2.2 or the 3.4 kernel on 4.2.2?
I've never had any issues on Slim Bean, Liquid Smooth, ChaOS, SuperNexus, Carbon Rom, CM10 WFTN.
On top of that, make sure you're using the original charger and usb cable too because using different types of cables
with the same type of usb port can also be the issue. ( Short, Long, MTP or PTP type for PC's only etc )
Also is your FAST CHARGE ( If supported by the kernel ) on?
Or is your usb cable / plug not connected all the way on both charger and wall port.
It could be a ton of different issues.
My friends wife had a problem when she was using 4.2.2 AOKP.
Turns out her original PLUG was the problem and she was using her husbands Note II plug just to charge the battery but
she still is using the original E4GT usb cable.

The cable shouldn't make a difference in how long it takes to charge unless it's an inferior cable. Note 2 and Epic 4G Touch are both Samsung cables, I can't imagine that they would make the Note's cable inferior to ours
Also, search through these forums and you'll find that the recommended cable for this device, actually is a Blackberry cable.
I had to get a replacement phone because my charging port was fried luckily I had insurance so the replacement phone was free. Initially my charging port was lose and the tech support at sprint tightened it up but it was all down hill from there...just an update to my previous post .... It was a hardware issue not a ROM issue.
