He's jerking your chain... most people say stock kernels are better... they are in a sense as you get more support direct from the CM team with stock. But there are currently three alternative Kernels that have modifications that the stock kernel does not feature : Voodoo sound & color, Overclocking & Undervolting etc.

Samurai Kernel which is what I recommend because its what i use. However there is also the Shadow Kernel another good kernel, and lastly the Nyan Colonel. All of them are great kernels, if you want to know which is best... try them all out for a day or two.
[Epic 4G Android Development] lownox:
The stock kernel did actually get some updates. :)
[Epic 4G Android Development] KennyG123:
But note alternate kernels are only supported in their respective threads...not here. Do not report problems here if you are not using the kernel the ROM comes with.

epicmtd Kernel: Add CIFS and FUSE

Speaking of the new updates made to the kernel.... how does one use the new CIFS support???

On the same sorta note, the app "Samba filesharing" hasn't worked right for me after beta 2. It no longer turns on when the wifi is enabled (mainly when the screen is turned on, because wifi auto turns off/on with the screen) So when I open the app, it acts as if it wants to force close, but if you hit "wait" it snaps right out of it. Also, when you try to transfer a large file (oh' say, the new CM9 Beta release ;-) ) It sometimes just sits there and the transfer never starts

I had hoped this was just a problem with my install, but after a couple flashes and clearing of data the problem is still there.
[Epic 4G Android Development] styles420:
The constant percentage issue is probably a function of the heat - it increases electrical resistance.

But you say that your brand new, slightly higher capacity battery is having the same poor battery life, eh? That gives me a tiny amount of hope that my battery isn't as worn out as I've been thinking... but doesn't solve either of our problems :banghead:

I suppose it is not impossible for our phones to be wearing out a bit, such that the charging hardware is not functioning as well as it should... but that is purely speculation...

Unfortunately, I'm at a loss for more ideas - I'll post anything I find out that helps my situation, and I'll keep an eye on your progress in case you find something that might help me :)

Good luck on your quest

EDIT: I have been meaning to ask about wifi - I have been noticing faster drain while connected to wifi than with the weak 3G signal I get at home. It was definitely worse when I had the sleep policy set to never, as well. The only reason that seems strange to me is that I still remember the days when that was a battery saving tip (going back to the SRF days - maybe it -was- better on battery with Gingerbread/Eclair?)

Can anyone weigh in on this? Is my experience normal, or are there specific problems I should be looking for? (I'm really just hoping that I have an issue that can be solved through software, but I am leaning ever closer to concluding that the fix will be a new battery...)

Oh, and this problem has remained through all of the ICS roms, and didn't change after several Odins, so I'm probably banking on false hope that there is a software cause... but perhaps there is something I have overlooked, that could persist through all of those clean installs...

[Epic 4G Android Development] Tomcat5:
I had this same problem on CM9 and am still having it on AOKP. In the car I have an inverter outputting 1 amp and it still drains about a percent every 5 minutes while streaming. If I am using 4G on a trip with navigation, forget being able to get to my destination with the phone still having a charge. My battery life is always horrible when the screen is on. I heard that our phones only can take 900mA. Is this true? Should I try and find the original 750mA charger and use that instead of my 1 amp Palm charger? This is getting ridiculous. My friends Bionic with a dual core and 1800mAh battery gets better life than my phone and any battery, even a 3500mAh Hyperion.

Sent from My Phone with An App

Edit: just checked my battery stats. Check out this. I'm on AOKP right now but CM9 does the same thing. This is in the car hooked up to the charger the whole time... It doesn't say charging because it really wasn't. It was just pretty much derping. Steaming TuneIn murders this phone for me.
[Epic 4G Android Development] robl45:
Huge difference between peoples rom and cm9 on my phone. sluggish with stock kernel and nyan v5
[Epic 4G Android Development] styles420:
@Tomcat - it is possible that too much amperage is causing too much heat, which impedes electrical flow - the 1 amp charger could be defeating itself as a result... I actually plan to look into this more, because I have a car charger I'd like to give to my sister for her Hero, but the charger is more than an amp (1.2, I think).

I'll try to remember to let you know what I find, but in the meantime I would recommend finding a charger that is closer to the stock rating, just to be safe - over-amperage might actually cause damage to the phone and/or battery, if for no other reason than the additional heat generated within
[Epic 4G Android Development] robl45:
interesting that you say that, I have a car charger from mono price that is an amp or so. The phone gets very hot but thats usually when I'm using it at the same time. I thought the phone would only draw as much as needed?
[Epic 4G Android Development] styles420:
That's what I'm uncertain about - where does the extra amperage go? It depends on the design of the charger and so forth - does it produce up to its rated amperage? Or does it always produce the maximum?

If it always produces 1 amp (or whatever the rating is for any given charger), then the extra amperage can't just disappear - usually, it would be expelled in the form of heat. That would explain the excess... but it could also be caused by a number of other factors, so that reasoning is by no means conclusive. I'm too rusty on electrical mathematics and such - hence my need for further research.

Another possibility is that the charger does only produce as much amperage as the phone draws (within its rated specifications, of course) - if that is the case, then perhaps doing too much with the phone, coupled with an over-abundant amp supply, could cause the phone to need, and therefore pull, more amps than it can safely handle (this is definitely possible - it is part of the equation when we fry electronics or electrocute ourselves, lol - clearly, no material inherently pulls only what it can handle) - in that case, the proper charger would be designed to cap out below the phone's maximum amperage threshold as a safety measure. I think there is some credibility to this theory - otherwise, all chargers would be designed to exceed the amperage, so that they could all be mass-produced with the same specs - it costs (at least slightly) more to have different setups for similar products with minor variations, than to make them all identical. I think that the very fact that chargers come in different ratings suggests that this theory could be at least close to the truth...

No problem. I'm glad it helped. FWIW, I always DL the files directly on my phone (usually by WiFi) and check md5 on the file using ES File Explorer. No use flashing a bad file!

I would love some help if anyone knows where they're located now on beta 4........ sooooooo please anyone help any way you can :) & thanks for the new beta 4 build its tha shizz nit!!!!!!!!!!!!!!!!!!!!!!!!!!!!
[Epic 4G Android Development] amateurhack:
Ummm, no, it does not always produce 1 amp. It always produces 5 volts, and it can deliver up to 1 amp of current at that voltage. The amount of amperage it puts out is dependent upon the circuit it is attached to.

The phone's battery has circuitry which protect the battery from over charging, as in when the battery approaches a full charge, it will limit the amount of current (read amps) that goes into the battery. The biggest part of that circuitry is that as the voltage of the battery and the voltage of the charger equalize, the battery becomes more impeding to the current. But it will still take some which will over-heat the battery, causing the voltage to drop causing more current to flow into it, starting a vicious cycle and then you eventually fry the battery. The battery protection circuitry prevents that from happening.

Now how much the phone will draw is a function of the combined draw of all the various circuits. When the battery is dead, it will draw the most current, followed by the screen, the 4g radio, the cdma/evdo radio, and then the other smaller radios, and then the phone's cpu and various other electronics. The more stuff that's on, the more amps it will draw.

I have overheated my phone to the point where it told me to disconnect the charger, running it in my car with the stock charger and an inverter. I have also used it on long trips with everything running for extended periods of time (I'm talking like 12 hours in the car on a long trip) with no overheating on a palm charger (that I have left over from my palm pre.) The difference being that when it overheated, I had the screen on, and when it didn't, I had the screen off.

It sounds to me like this guys battery is fried. It had nothing to do with the Palm charger, though. He's just repeatedly putting it into a situation where it overheats.
[Epic 4G Android Development] Tomcat5:
Interesting situation right now. In the car with a functioning alternator, and the phone drains about the same on battery (trying with my 1 year old semi used stock 1500mAh) as it does with my 1 amp Palm charger, 1 amp Belkin charger, and the USB output on the car inverter which supposedly puts out the normal USB amperage of 500mA. This means my battery is toast? All I'm running is navigation, so there's no WiFi, BT, or WiMAX in the background.

test results

I just restored my backup of CM9 B3 and upgraded to B4. I'm posting to report that it does NOT behave the same when plugged into power as when it is running off battery. All bluetooth devices work as expected when plugged into power. Running off battery, they cannot communicate with the phone unless it is awake.

It's breaking my heart because ICS runs like butter on my Epic otherwise, but until I can hop in my car and have my speakerphone work without having to dig my phone out of my pocket and power it on first, I gotta stick with GB.
[Epic 4G Android Development] Shinydude100:
What looks washed out? I'm not kidding. Lol. Thank goodness I found my 12MP Camera, I'll be taking a snapshot with/without voodoo color with the adjusted settings to show it.
[Epic 4G Android Development] KennyG123:
Let's not. Every phone is different for one and second last I checked voodoo color is not in the stock kernel. You should take this discussion to the kernel thread you are using. Thanks.
[Epic 4G Android Development] amateurhack:
Here's what I suggest: let your phone go completely dead until it shuts itself down. Then, with the phone still off, connect it to a stock charger and let it fully charge. If after 2 hours your battery isn't full, then it's bad. Batteries that are really fried will never reach full voltage. You may notice that its very hot just from charging.

If it does take a full charge, then give it a test run without being connected to the charger. See how long the battery lasts on its own. If it goes for a while and then suddenly drops, it is likely that the battery is bad. As batteries fail, they will hold a "surface charge" where the voltage will seem nominal for a while, but then once that surface charge is used up, the voltage will drop dramatically.

Sorry to everyone else for the off topic battery discussion. Breaking my own pet peeves here. Mangling Ohm's law just makes me crazy.

I'm still getting a ton of random reboots with this ROM - is anybody else still experiencing this?

I've tried everything from wiping cache and dalvik, reflashing, downloading + checking the md5, and even as far as reverting back to stock, rerooting, then reflashing.

I'm using the stock settings/kernel. No data was imported from old roms.

It seems to happen at the most random moments, typically I'm either in the browser, the Google Reader app, or Plume - but that might just be because I use them the most often. I use SwiftKey X as a keyboard. I'm really clueless, because otherwise this is a great ROM.
[Epic 4G Android Development] DarkIceCream:
The same problem continues and I've flashed and activated a new epic so this is deff an issuse in the rom, Always ALWAYS ALWAYS reboots when I turn the option on for USB pc connection as soon as its on the phone reboots and when I unmount the sd from the settings it reboots. SO it seems theres a bug with SD card unmounting and REBOOTING ^_^ great rom non-the-less everything else works spic spack
[Epic 4G Android Development] Shinydude100:
No prob Kenny, I'll keep this at a pm level I guess. Warren Togami himself said that the only thing keeping it from being on stock is figuring out what values will correctly match stock colors. Hence, I mentioned finding values that seemed to fit the bill, but alright. No more talk of it. Thanks.

[Epic 4G Android Development] gundamfan:
I can verify that your theory is correct. When plugged into the car outlet, the Bluetooth connection is stable. Once unplugged it goes through a continuous cycle about every 2-3 minutes where it connects and disconnects. I experimented by changing the modems and still have the same problem. I am running a clean install of CM9 Beta 4 (stock). Would it help to report this to the bug tracker?

On a side note: this is my only issue I have with this rom. I'm coming from CleanGB and took the plunge to CM9 and all I can say is wow! You all did a marvelous job! Thank you!! :) Let me know if there is anything else I can test out regarding the Bluetooth.
[Epic 4G Android Development] Mutiny32:
Two questions:

1) Are you going to make a new build with upstream Linaro optimizations added? A 100% increase in CM9 performance over previous AOSP is more than a minor improvement.

2) Is 4G with CM9 on the Epic4G a lot slower to connect as well as being much less reliable? I've noticed that 4G has to be "nudged" into connecting sometimes and when it does connect, the TCP/UDP connections seem to take FOREVER to setup. Perhaps it's just Sprint/Clearwire neglecting WiMAX and de-emphasizing the technology because of LTE or the FC09 modem being just worse than previous SDRs in regard to WiMAX in general.
[Epic 4G Android Development] bit1:
I'm with you. My phone has been getting random reboots a bunch but I can't explain why. Maybe we should post a Logcat over on the issues forum. I'm going to have to go over to an FC09 ROM for a bit of stability as I'm going on a business trip and can't afford the reboots.
[Epic 4G Android Development] tmcwilliam01:
I'm getting the reboots too but since I am running a third party kernel I have not posted but since there seems to be a few others seeing this I throw out my situation. My reboots seem to happen when streaming. It's happened while streaming iheart radio and on HBO Go.

[Epic 4G Android Development] wtogami:
Will be interesting to know if the standard CM9 kernel makes your reboots go away.

beta4 with standard kernel and no mods is perfectly stable for me.
[Epic 4G Android Development] Shinydude100:
I've never had a reboot because of any of the CM9 Builds, it's always boiled down to apps, and or choking my Epic's Ram, hence, I've changed the way I use my epic, as well as keep my apps that I regulary use to essentials, leaving only a few unnecessary apps as a luxury. I close out running apps before and after I use my phone. I'm using a third party kernel, and I have never had any reboot issues with it, even more, never had issues with stock CM9, (I'm usually running stock CM9 for a week or two for edification of testing out bugs for our devs)
[Epic 4G Android Development] wispoffates:
I can answer you on #1 we follow CM9 upstream closely to give our users the best experience possible without unstable patches getting in the way. We will likely wait till this merges upstream into CM9 itself which appears to be in progress.

2) I am having trouble finding a live link to root the epic. I downloaded the drivers but all the files I've tried to click on for rooting the device itself have all said "file cannot be found"

Any help would be appreciated. She complains constantly that the twlauncher freezes all the time and gives her error messages. Her physical keyboard on the phone doesn't work and random apps launch randomly and freeze up her phone so im hoping rooting and flashing a new rom will fix all these problems that seem to be stemming from the stock software that is preinstalled on the phone.

The rom is rooted so all you have to odin cwm into the epic and flash the rom it will be rooted. You also have to flash the Gapps zip as well. This rom will install its on versión of cwm and will also convert the whole partition of your phone from bml to mtd. Which means if you ever want to go back to stock or any standard bml roms you will have restored the phone using odin and replace tar and pit files and also check repartition while doing that. Any nandroid you may have will also not restore once converted to mtd. Everything else is on the upside and much improved benefits.
