Battery Re-charge

Has anyone else ran into an issue where once you switched to a custom rom that it is taking nearly 4 hours to get a complete re-charge even while connected directly to a outlet and not a PC? I am having this issue if anyone has any advice its much appreciated.
Ive seen this both on Skyraider and Virtuous 2.7

It's a problem with every 2.2 Rom.

Turn your phone off for a faster charge....and play around with SetCPU to find a profile and settings that works for you...other than those...nothing I can think of.

USB cord vs wall charger
May be a placebo effect, but my device charges (seems to) charge much faster when plugged into the wall charger vs. the USB cable into the PC. FAR faster charge when device is off, in either charging scenario, USB or wall charger.

Started a thread about this a week or 2 ago. The more power you give any smart phone, it seems, the more juice you're going to use. until battery technology catches up we just have to find better ways to charge it. my newest solution, adding usb ports in my car. best thing about it is now I use my phone as dash mounted navigation with Google maps and navigator, works better than any car gps I've seen, probably because Google actually updates their maps automaticly.

On CM6, I've learned that if you turn your phone off, plug it into the wall charger, wait a few seconds after the LED turns on, then boot up your phone it chargers at about the normal rate of 1% a minute which was the rate back on stock 2.1. I cant say if this works on the other roms cus i havent tried it on them.
The consensus is that the OS is keeping the phone from charging properly in 2.2, but the RMF that controls charging when the phone is off works normally and somehow retains the correction even after booting the phone up while charging.
BTW, this definitely isn't a development topic...had you looked in Q&A or General, you would have found at least 5 or 6 threads about this issue.

if I remember correctly, the os sense whether the phone is hooked into a computer or a wall charger and adjusts the amount it pulls accordingly.. I think that the phone will pull 1amp when hooked into the wall and 500-900ma from the usb.. don't quote me on this, as i read it somewhere on here awhile ago i think... also, this would make sense to me as usb 1/2/3 all are capable of different power amounts and this sensing ability built into the os/phone
usb power on wikipedia:
http://en.wikipedia.org/wiki/Universal_Serial_Bus#Power
/edit: there's also something at the end of that post that mentions that under certain circamstances usb can supply 900ma - 1.5A of current.

That is how long it takes to charge. The cord that came with my phone has a sticker on it that says. " Full charge takes 4 hours standard. 5 hours extened. " It's always taken that long to charge my phone if I let it go down all the way.

Today was the first time it took my phone 4+ hours to charge, the only thing i changed yesterday was my radio from a 1.x to the newest one. It may be a fluke but maybe its radio related?

I believe King said he designed his kernels for faster charging.

[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.

[Q] Battery % drops while charging

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

Battery discharging vs not charging

When my Galaxy Nexus GSM is not plugged in, the battery shows itself as "discharging". Previously this used to be "not charging". I have tried multiple (Jelly Bean) ROMs, different cables, wall and USB chargers. Same problem. The larger issue: my PC no longer recognizes my phone and I have resorted to using AirDroid to transfer files.
Can anyone shed light on this issue?
I have done full wipes, including wiping battery stats.

Mine was always discharging...
And make sure that you got fast charge off if you have that on. That disables MTP capability.

I have exactly the same problem...see my thread...its recent!

I had a similar issue, and then not long after the phone refused to charge. I had to take it to get serviced, and the ended up giving me a refurb instead.

I think it has to do with the temp of the battery, if its too hot and you have it plugged in it will say discharging.

First, don't use a charger other than the original. The different volts mess with the NFC chip and antenna. Try disabling NFC and rebooting. Leave NFC off and try to charge. If that doesn't do it I have another option that might work but I'm CDMA so you would have an extra step to change lines in file.

Thanks for the suggestions, guys. I tried disabling NFC but it had no effect. My phone is the international version (the box was in Polish) which is not warrantied through Samsung USA, so I guess I'm out of luck there as well. I'm just gonna hang in there until the next Nexus phone, I guess.

When will people realize that the difference in voltage won't cause any problems with the phone as long as they're within safe range.
I've been using the charger that came with my G2 (htc) on my nexus for months and have no problems. I would've continued using the original one that came with the nexus but it had an annoying whine to it.

Really because it sure seemed to be my problem a while back and anytime i use a different one. Guess samsung and google must not know what theyre talking about.

Chargers are rarely the problem, however different usb cables might be the problem instead.

Am using samr original charger and cord. Works fine

I have this same issue
My Galaxy Nexus from Verizon has worked flawlessly for several months now. It updated about 4 days ago to JellyBean 4.1.1 and I have been charging the same two wall chargers, car charger, and USB cables every day since I got the phone. I even was using the USB charger to deploy and debug a simple application I am building around noon today. This evening at about 8 PM while on the wall charger I noticed the charging stopped. No lightening bolt icon, status says Discharging, and I noticed one time that it said Not Charging. Neither of the wall chargers work, nor is it recognized by the laptop using the USB cable. It is at 65% charge and is dropping fast. It seems that no one has a fix for this other than replace the phone.
Very difficult for me to believe that the USB port just went bad using the same chargers every day. Hard to blame JellyBean that has run at least 4 days with no issue even though several sites point to a possible charging issue. I even dialed *#*#4636#*#* and checked the battery status, and it's health was good. I have not rooted or placed anything on this phone that is obscure beyond my simple near "hello world" development apps. I have rebooted, and performed a battery pull with no such luck. With the number of posts pointing to a JellyBean issue, and users experiencing the same issue after the upgrade to 4.1.1 I am leaning towards this being a software issue, but it is interesting at the number of posts saying that the their only fix is a refurb phone replacement from the carrier.
Pretty odd occurrence, and extremely frustrating. As I said the phone worked fine all day today. This just started a few hours ago for me.

OK I have fixed my issue. and it does appear to have been hardware related. I will preface this with you must be very careful not to break your phone with the solution below. I read several posts about using contact cleaner on the USB port, so I looked at the port on the phone and noticed that the "toungue" inside the reciever USB port appeared to be slightly bent down. With the phone off and battery removed I used a needle to wedge under the toungue and bend it up ever so slightly making sure I would not break it. Pluged in the phone and it still did not charge. (That was last night) this morning with the phone at 55% and thinking it was going to need to go back to Verizion I did it again phone off and battery removed only this time a bit more forcefully out of desperation. I definitely moved the "toungue" up and even had a bit of difficulty getting the USB cord to slide back into the connector. But when it did the Phone is charging again. Appearantly I must of jammed the plug into the phone upside down last night when getting into my car and bent the "tongue" in the USB port. Lesson learned, and hope this helps others.

Means the battery has been recharged and discharged to the point were it holds less of the charge. Basically its an older battery, or its been tappered with with, probably a rom using to much ram or pussing the device a bit too far nightly and ported roms could be the cause I say stick to stock kernal unless you really now what to do
Scrap that wrong fourm I think

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.

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.
