[Q] Kernels and charging

I've been messing around with roms for a while now, and I've finally chosen one that I really like, but the other day I decided to start playing with kernels, and I flashed netarchy-toastmod-4.3.2-cfs-sbc-havs-more-universal-signed. Once I flashed it, my phone would no longer charge at all. When I plug it in, the orange charging indicator would come on for just a second, and then turn off as if I unplugged it.
I had this happen once before, when I installed the fullHDMI app, I read that if I installed a custom kernel I would get better performance, and the same thing happened.
Luckily I am OCD about most things I do, and I ALWAYS Nandroid, so I was easily able to revert back to my former rom and kernel with no problems.
And the last time, my phone would charge fine if it was off, so worst case scenario, until I did a restore, I could get by just turning my phone off and charging til it was ready. But this time, my phone wouldn't do either! When its on, again, light comes on for a second, then turns off. And when its off, I don't even get that much!
I have never had an official htc charger (bought my phone on Craigslist and the guy "forgot it"), but I used to use my old Samsung Reclaim charger with no problems. Therefore, I can't remember whether or not the charger I'm currently using (stupid Rocketfish micro usb charger from best buy) ever charged my phone when its off.
Which brings me to my question, really. How do kernels affect charging on the Evo? I've read elsewhere about people having issues after flashing a new kernel. And really, does it matter if you're using an aftermarket charger or the OEM htc charger?
I would love to be able to play with new kernels and see what's best for my battery life, but every time (btw, if its relevant, the 2 times I've tried flashing a kernel without a full Rom I've had charging issues) I've tried I run into trouble, and I am terrified that I'll flash and forget, and won't have enough battery life to restore to my old kernel!
Edit: Also, whenever I forget my charger at home, I can usually find one laying around at work, and the one I usually use, some AT&T micro usb charger, has never worked unless my phones off, even with the built in kernels. It works perfect, on or off, with my buddys stock, non-rooted Evo. I haven't tried it lately, so I'm not sure if it'll even charge while off. I just feel like my charging issues are kernel related, and I wouldn't think the kernel would affect anything while the phone is turned off? Do different kernels work only with certain chargers? And do some chargers only work when enabled by certain kernels? I find it hard to believe that there's anything physically wrong with my phone when I can always restore and get it working again, but at the same time, its weird to me that some work while my phones off, and others do not.

Update: Just tried the Rocketfish charger while off. Phone does not respond to it whatsoever.. I need my Reclaim charger back! But again, this raises the question, do some chargers only work when enabled by certain kernels? Why would this charger not work when the phone is off, when no software is running, but work fine when its on and certain kernels are running??

Nothing??
Does anybody know anything about this?

that's weird man. if your phone isn't charging even when the phone is off, then it's not kernel related, it would be hardware related (possibly your charger port on the bottom of the phone) i read somewhere that the charger port has been reported to break off easily. have you connected it to a computer to see if the computer recognizes it?
edit: i noticed you were using an SBC kernel. I'm not gonna get into the whole debate about if sbc fries batteries and stuff, but have you tried swapping out your battery for another one? maybe the battery is fried?

I think its your charger too. I've had other phone (hybrids..yuck) that were very charger sensitive so it would not surprise me at all. THIS is the same charger that came with the phones so it will work or if your an ebayer like myself than go THIS route since its cheaper. And I've used SBS kernels since they first arrived on the seen and still to this day have had no problem, but everyone is different.
I also have had a phone with a broken usb port. It wont let you charge unless the port is wiggled just right and as soon as the phone is moved itd stop charging. Your issue definitely sounds like a charger problem to me.
Also, next time try to sum everything up in a paragraph or so. Many people will turn down a question when they have to read an essays worth of info.

Yeah sorry, I know I wrote a novel. I was kinda drunk and wanted to get the facts out there. I know my problem is not hardware related though. Charges perfect, no wiggling required, while my phone is on. Won't charge whatsoever, no matter how much I wiggle, with the phone off. It's just weird to me..

And the second the kernel loads after the boot animation (screen dims and 4 softkeys light up) my phone starts charging. Can a kernel make a charger that's not compatible compatible?

I believe the kernels are based off of HTC Stock Kernels, they are just tweaked to achieve greater performance. I've never seen any evidence of Dev's adding/removing charger compatibility so Id say its safe to say no.

I've never experienced anything like that before. Very strange. I wouldn't think that a kernel would prevent the phone from charging while the phone is powered off. I also wouldn't think that a kernel could make an 'incompatible' charger 'compatible'. If the charger is Micro USB, it *should* be compatible. I always use the charger that came with my phone, but I have used other ones in a few different instances, and have never had a charging issue whatsoever. Some chargers have different ratings, such as 1Amp charge output, or .5A charge output. Generally USB and car chargers charge at .5A, while wall chargers charge at 1A. The Evo should charge with either one, as long as the cable is Micro USB. I just don't see how a charger could even be 'incompatible', unless the charger itself was no good. My guesses are, either a bad battery, or a bad connection where the battery makes contact. Or, a hardware issue. There is a known problem for some Evo's, where the solder joints that connect the USB charge port to the motherboard fail. Poor solder joints. That could be your problem. I just don't buy that it's software related, because the phone should charge when it's powered down, regardless of the software. However, it is strange that this happened right after changing kernels, and nandroid restoring to your previous setup alleviated the problem...that is strange. I guess the easiest and least invasive thing to try would be flashing a few different kernels, and see how different kernels affect the problem. If the problem persists no matter what kernel / rom combo you're on, then it's not software related. If the problem goes away when you change kernels, then maybe somehow it is software/kernel related. It's just very odd.

Bizarre Battery Behavior since Flashing to a 4.2 Rom.

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.

Flashes Liquid Smooth 4.2.2 on my wife's E4GT about a week ago. She has been having the same charging problems, no issues on 4.1.2. I have flashed many 4.2.2 ROMs with no charging problems. I will restore 4.1.2 on her phone tomorrow and see if that fixes things

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.

[Q] Car charger problem. Says still charging after disconnecting

OK, so I have scoured the Internets and xda and haven't found the exact answer I am looking for and don't have anymore time to search. I have a car charger issue and hope someone can shed some light on the issue.
I have tried to different USB port car chargers and both have the same problem. They are both 1 amp, the second is a 2.1 but both ports only get 1 amp. Upon connecting it takes a good few seconds for it to recognize that it is charging. Upon disconnecting, it takes a good 10 seconds for it to show that it is not charging as in it still thinks it charging.
I don't have this issue with the oem charger nor a 6 year old LG charger that works great with this phone plus it being like 8 feet long. I have also gone through a couple cheap car chargers that didn't have this issue but the connectors go out quick. So I thought I would just get a usb port charger so I can use my oem cable but this is bothering me. Is this just what these little chargers do?
Thanks for any input.

Not sure if you're on AOSP/KP/CM, but I've had this issue on these roms once in a while, only with USB charging. I've never experienced it on the stock rom, and never while charging with AC.

i have that defect too even on stock firmware unrooted my mini port got bad and got it fixed and still does that
Sent from my useless no data sync gs3

I am Stock, unrooted.
Maybe one day I'll go back to the dark side Just couldn't find the perfect ROM. So cleared my counter, used kies to restore stock firmware and been running stock for the past month.
Thanks for your input already guys. It all helps.

A quick reboot always fixed the issue for me

Have rebooted and removed the battery and same thing. I also tried another usb port car charger that was in someone's car and same thing. I wonder if it's just my phone. It seems like the phone charges just fine, but it still worries me that something is wrong. So guess I will just have to sit and wait for someone to shed some more light. Thanks to all so far.
I am currently on vacation, but when I get home I am going to re-root my phone flash a few ROMs and see if the problem persists. If it doesn't, it's a ROM issue. If it does, it's a phone and/or battery issue. Maybe someone can shed some light before then so I don't have to start over again

OK, so just rooted, flashed SlimBean and Lean Kernel and same thing is happening. So obviously its a hardware issue. Will update if I find out anything more before someone else does.

Note 2 charging complete randomness - bad port?

Hey guys:
I'm an IT tech and I'm really confused on this one. Started happening a week or 2 ago. I'd be charging my phone and it'd randomly cut out. I run Carbon ROM and have the notification light set to be a solid yellow when charging so I know if it's charging or not. It would happen very infrequently, but would cut out. I'd unplug and replug and it would be fine for the most part. It's gotten progressively worse. I was running NEAK kernel so I tried to go back to stock Carbon trinity kernel, same problem. The other day my phone would also randomly go in and out of "car mode" too which was weird. Currently, I have it plugged into my computer so it's charging in USB mode (lower voltage) and as of right now it's holding charge. But prior to last rebooot it was going on,off,on,off with the charge. Today my phone has locked up a few times when plugged into a full AC charger even. Seems to be completely random right now. I'm just looking for any advice. Going to flash a different ROM and see if that does anything. If not, what part would I need to order? I saw a Youtube instructional video on how to replace USB port and I'd be willing to do that. I bought my phone off Craigslist and have had it for like 6 months. No proof of purchase, which you need for Samsung warranties right? The battery is not "swollen" in the middle. Oh, also this morning, when it was going in,out,in,out,in,out constantly (on full AC charger), i could actually HEAR the (official Samsung) charger resetting itself almost, in sync with when the charge would cut out, if that makes sense. I could actually hear the charger making a "click" everytime it would lose charge then it would try charging again, and would click off again, over and over. Lastly, today I also saw in settings->battery it saying "charging" even though the charge light on my phone was off AND i saw it drop a percentage so it wasn't actually charging. VERY random. Maybe clear battery stats? Doubt that'd do anything... I have CWRP on my phone...
Any thoughts at all on this or if you've seen this would be great. Likely new USB port needed. Where to buy? If new ROM does not fix, it must have to be replaced. That's all I can think of....

Currently, it is holding a charge. I re-installed NEAK kernel, and set the AC charging to 1000 instead of the default of 1700. This happens though. When it seems to be holding, it's fine until I unplug and try later and then all the randomness begins. No idea what to think of it. Don't even know if setting to 1000 had anything to do with it working, likely not....

Didn't see it mentioned. Have you tried a different cable or even a different charger? Would do that before changing a usb port on the phone. Doesn't sound like the port if you are able to charge via a PC USB.

[Q] Charging problem, tried the following...

Ok so a little of background story, if you don't care about it just skip to the next paragraph. I bought my T989 over the internet, it was working perfectly. I wanted to make the most of it, rooted it and tried Swapper 2, which hard bricked my phone. I'm not new to rooting, I've rooted some phones now, but I had never tried swapper, I liked the idea of unoccuping some RAM memory. Apparently I did something to my boot sequence thing and my phone was dead. I still had waranty on the phone (one week left when that happened so it is suspicious to anyone) so I called. After one hour of arguing over the phone and trying to convince them it wasn't my fault, which of course I knew it was, they decided to send me a new one... ahem "new" one.
Ok so here's where the priblem start. My "new" phone was working alright untill it stopped charging, didn't work AT ALL. I took a peek and one of the pins on my phone was bent, it was upwarda and as I tried to get it back to its place it fell off. I took my phone to get the MicroUSB replaced andsure enough they did.
My phone was charging again correctly. It was doing great untill it stated to charge slower and slower. It got to the point where it just shows as charging, but doesn't charge at all.
I've tried everything, I bought a new original Samsung battery, still same issue. I downloaded an app to tell me the amps the cellphone was pulling and it shows 350-450 when I have read it needs minimum 600. I have tried custom roms, kernels and nope, still pulling 400, tried LG chargers, Motorola chargers, a SAMSUNG S3 charger and still no luck. The thing they all have in common is that they're USB chargers so I read if the cellphone detects it as such it would give me a hard time.I've tried making a fast charge USB cable with a video on Youtube but it still only charges 400 mAmps. I've installed custom kernels with the "USB fast charge" and STILL no luck.
The ONLY thing I haven't tried is using and ORIGINAL, Samsung wall charger but at this point, I think it won't fix my problem because of the fact that I remember it worked well in the beggining. I am currently charging both batteries with a Universal Battery charger, but I've read that they wear out batteries throughout time.
So, is there another thing I haven't tried... or is my cellphone doomed now? I believe that it's the phone, as in the mother board if I can call it that, or does anybody have another theory?
Thanks for your time, would love to see anyone suggest

I know this isn't an answer but a general comment. This is a good reason why I will NEVER buy electronics that are used or from a retailer that isn't a big name. I don't care what the seller says there is just really no way to know exactly what you are getting. If you had bought this phone from Amazon (direct) you could have already got another one by now with no arguments. I'd be looking for another phone and call it a loss.

Thanks dude, I know it really matters on where you buy it, but the price was just so handsome to me. I guess that's what I get and as things like this happen you learn more and more on what you buy and what you decide to do with them. I guess I already consider it as a loss but I'm aware that it's not unusable yet. I guess I will continue to charge both my batteries with the charger, but I was just curious to know what really happened to the phone to avoid things like this in the future

What apps do you all have installed on your phone and running while you are charging it? Try making a full backup then do a clean install of your ROM (backup just in case this doesn't fix it). After doing this do NOT install any apps, just test charging. If charging works, it is some app on your phone. I know those "battery saving" apps can eat up a lot of battery if configured wrong. And if you have a lot of background apps running, they can eat your battery without you knowing and reduce charging time.
Go into settings->device and check what is eating up your battery there before charging and during charging.
If you don't want to re-install your ROM, try charging your phone with the screen off (no screensaver (daydream) or nothing, just screen off, charging) and in airplane mode. I recommend doing a clean install to see if it is some apps (you can use TB to back everything up, then do the clean install and test from there).

The ROM I currently have has a great battery saving mode, I also have "Advanced Task Killer" to kill any apps. It's the same issue. I want to buy a new charger but I still think that won't fix my problem. I've also charged in Airplane mode and no luck

Can you go into settings->Battery and post a screenshot of it? I'm curious as to what is eating up most of your battery.
After, I would still try doing a nandroid and flash your rom cleanly and install 0 apps and try charging on this clean install. I know my friend ended up getting some battery optimization app installed (which she claims she never installed, but it is on her phone) and her charging times were horrid. It also made the phone quite laggy. I imagine if you got 2 or so of these types of apps on your phone, it could eat your battery instead of charging it.
Also, when you charge it, it is a strict charging cable not a MHL adapter right? I know when I have my MHL cable hooked up to my phone it claims it is charging, but it actually drains the battery slowly. (MHL is micro USB -> HDMI).
Since you have tried multiple chargers and cables, I would be looking at the phone as being the problem. Also, look at the contacts on the bottom of the phone and look for any bent pins. I wouldn't try to fix that yourself, but if they are bent, I'd take it in for repair. those pins are very fragile once bent and can break off if not handled very carefully after they are bent.
If you can get into adb from your phone to PC, then the pins on your phone should be good and the USB cable should be good. Does it charge if you put it in fast charge and plug it into your PC?

The pins are alright. As I stated, I recently changed the MicroUSB port, well I paid somebody to do it and it was working fine at first but then stopped charging, well, not stopped charging actually. At first it started to charge slower and slower untill it got to the point that it just says it's charging but it doesn't charge. It COULD be to the fact that I flashed new ROMs, downloaded games and all but I doubt it since now I have a brand new ROM with no games (or not that many) and you can see from the screenshots I uploaded that nothing's eating my battery
Well except for my screen, I had it at 80% brightness lol. Usually I set the brightness at the lowest (no Auto brightness to save battery) and my wall paper is color black since I heard Samsung phones do save up battery with black since it doesn't light the LEDs or something like that.
And yes, it's strictly USB cable. When I activate "Fast charge" and if I connect the phone to the computer it just shows the notification "USB connected" for a second and then disapears.

the screenshots attached were helpful. I don't see anything in that list that looks like a huge battery sucker and since you say your rom is fairly fresh and clean, it likely isn't the apps. Are you sure the guy who swapped the microUSB port did it correctly? Improperly soldered pins (especially those tiny ones on a microUSB port) can be tricky to solder correctly if you don't have the correct tips. It could also be that something else got damaged while putting that on (if the capacitors were not properly discharged before replacing the microUSB port, they could have gotten damaged).
I think that your assessment that it is one of the boards (likely the charging circuit) got damaged. I'd go back to the guy who replaced the port and get him to check the charging board (specifically the capacitors) to see if there is any signs of damage or wear. Capacitors can get damaged really easily if the heat on the iron was set too high. I know I've damaged capacitors while soldering things before. Or it could be that the port didn't get a solid solder connection or ended up briding some pins. If fast charge is on, your PC shouldn't see a USB device being plugged in. If you have a multimeter, you could check the resistance on the 4 USB pins and see if any of the pins are bridged.

Well I took it to the guy from before and he couldn't find a problem with the phone's soldering, but even he wasn't sure what the problem was as if it's not his specialty. I do not have a multimeter :/
I was thinking taking it somewhere else and have them change my microUSB port to see if that other person might now a bit more. I'm sorry but I'm more of a software type of person, I clearly have no clue what the problem might be
THANK YOU for really helping me and taking your time to analyze my question, I really appreciate it thanks man
So if what you say is true, do you think it can still be fixed?

It definitly can still be fixed, it'll just be tricky. If they are surface mount capacitors, which they likely are, it is hard to tell when they go.

So what I should tell them to do is to change the capacitors? I can leave the same miniUSB port right?

I would tell them the symptoms and let them tell you what they think should be fixed. In my mind it is likely the capacitors on the charging board that need replacing, but without having the hardware physically in front of me and hooked up to a multimeter, I cannot say for certain. It could be a faulty microUSB port or a bad pin (bridged or microfractured), could be damaged PCB trace, could be gremlins
I would bring it in somewhere or give it to somebody and tell them that the phone doesn't seem to be taking a charge and ask them if they can look at it. If it is still in warranty, send it to Samsung to get fixed. If it is outside of warranty, take it to somebody who knows their stuff (likely a professional repair shop OR somebody who does cell phone or PCB repair for a living... hobbyists may be able to fix it, but to me this sounds like something that somebody with training should likely look at).
Since you have tested different AC adapters (including known-good ones) and different cables (including known good ones) and charged the battery outside of the phone, that narrows the problem down to being something with the phone. You narrowed down it is likely not software related, so that leaves hardware. I know from experience soldering very small components can cause bridges quite easily; even when done by the pros. Some bridges don't matter, but it is better to avoid solder bridges whenever possible. I know I had to replace my nintendo DS slot-1 due to a busted pin and soldering that thing with a large iron was a pain in the behind. Got it all fixed, but it was not an easy task.

This gives me new hope, I really don't mind charging my phone this way, but I'd rather have a complete phone with the ability to charge from a wall outlet
Thanks so much, I hope I can count on you if I run to anything else. And hey, you learn something new every day, ALL of this has been really helpful

Glad I can help. I used to work professionally soldering tiny components before moving into IT. Done some hardware mod to a few cameras, repaired a ps2 controller, have an old tube amp going fix soon too. I've seen a lot of weird things happen with bad solder joints or faulty capacitors.
