I think nobody asked this question before since I didn't find it even loking in Google
Since I got mi Desire I realised that not every charger works for it, I have an USB charger that went with a bluetooth dongle I bought (with same specs) but seems to be a lie because the battery keeps draining when plugged in, but that's not the problem I actually have.
My original HTC charger broke after three weeks of normal use , since there are no HTC stores in my country I went to an Apple store and bought and Iphone charger wich has the same specs as the broken stock one (Output 5V 1A). The problem is that sometimes when I plug the phone (usualy I charge my phone overnight), the screen becomes buggy, sometimes not responsive and sometimes over responsive (eg. if I click on an icon to move it into the home screen, it responds as if I clicked that icon several times very quickly). At first I thougt it was a ROM issue, but at this moment I already tried LeeDroid, OpenDesire and now I'm on teppic74's rooted Froyo and had similar issues in everyone of them. It's not really a mind breaker since I am ussually sleeping while charging, but I wonder if I'm not killing the battery or causing any kind of damage to the phone.
Can anybody give me a hand on this?
Thanks
Why not just order a charger online?
I don't know if it hurts the phone or the battery.
But if my screen went super-laggy and over-responsive by charging it..
I'd throw the charger out.
Already ordered, but I was wondering if someone happened to know a technical reason for this to happen, the phone doesn't overheat and the charging process works as a charm, the only issue is the screen wich sometimes behaves perfectly normal
Guess I will give the charger to any iphone owner when I get the original one (I have to buy in the UK store.. totally overseas)
My phone does the same thing if I use a PS3 charger (Just the usb to wall socket part). When I was in a phone shop, I noticed their Desire HD that was on display did the same thing. From what I can gather, it doesn't do any damage and happens with a lot of aftermarket chargers. Don't take my word for that though, hope I shed some light
Hello
Have same problem with my recently buyed HTC Desire while charging with non-original charger (from Nokia).
First time I'm worried about phone, but after reading charger's characteristics I found some difference in power.
So I think while phone charging it's receives less power than needed for normal work.
Today was the first time I let my phone's battery drain down to nothing and it died completely while i was on a phone call. But when it died, the screen went black as it should, but it refused to charge. The light didnt come on and it wouldnt power on. I had to pull the battery and then it booted to a 'critically low battery' notification on the screen. Has anyone experienced this kind of freezing when the battery is just on the verge of dying?
I don't have this specific issue, but definitely power draining problems on my Focus. I let it charge overnight - 10+ hours plugged in. That should be more than enough for a nice, full charge. Well it's been unplugged from the charger for a little over 3 hours now and it's already down 30%. All I did was listen to 4 songs on the Zune on the way to the office this morning.
Same thing happened yesterday. So two days in a row isn't looking good. By early afternoon yesterday it was almost drained.
I haven't even made any phone calls with this yet! I can only imagine what a handful of 30 minute phone calls would do.
hmm... faulty battery/phone? maybe take it back to the store and ask for an exchange?
Is there any way to calibrate the battery? Such as completely drain it, fully charge it then look around the settings menu for a way to delete any kind of battery stats file?

I was thinking the same thing, about exchanging it. I'm going to give it more time and really put it through some paces to verify. I've got until the end of November to exchange it.
This was all without any Wifi on too
I've noticed my LG-C900 also seems like a battery hog, and takes forever to charge. The Samsung SGH-i917 is a little better, but both of them have a tendency to run out of battery quickly if I forget to charge them overnight. It's a little worrisome to me.
I don't measure smartphone battery length systematically, but my Motorola Droid seems to do a lot better, and my HTC G1 has gone all week without being charged (although the graphics aren't nearly as good, the processor doesn't have to work as hard even to change menus).
On the other hand, the advantage is in both of those phones, it is much easier to change batteries, making it possible to carry an extra battery and switch halfway through the day, something you could never do with an iphone.

That would probably be a good idea.
you could look at the wifi status , turn it off when you don't need it .
wifi is "on" as default , if I don't turn it off my batt is dying really quick .
I didn't look at it but maybe you can also turn off the GPS .
The first Focus I got shipped from AT&T refused to take a charge. You could plug it in and the icon would change to a plug, but it wouldn't charge up at all. I replaced it at a store and the new one is perfect. Charges quickly and lasts much longer than my old Fuze. I don't know if it was the phone or the battery, but I'd just get a replacement.
For some reason my HD7 won't charge from PC USB ports-- it's been "critically low" in the morning the two times I left it plugged into a PC overnight (orange light on, but apparently not charging quickly enough).
The ports work fine charging my HD2 and iPhones-- apparently not with the HD7 though. Only dedicated AC adapters feeding a full 1A have worked so far-- not hugely inconvenient, but kind of odd.
my G1 and HD2 would exibit this behavior when on my car's USB port when the charge was low enough, and the last system update that came down for the G1 would just slow the drain when attached to my car.
The first trip with the HD7 in the car > home, it died on the car's USB port, very slowly. After its first full charge it does accept a charge from the car. I think it may have issues once it gets low enough just like the HD2. I think it may be the output, I don't remember how much power Honda supplies at the USB port, but obviously not enough for all devices. All my ports on my laptop, desktop and WHS, except the front ports on the WHS and the desktop, charge these 3 devices handily, the front ports on the home server and the desktop must only provide minimal power, I've had USB sticks complain and drop speed on these.
I am REALLY unhappy with this phone. Aside from the poor signal and other issues well known to the Nexus, I now have a phone that has a charging problem. Sometimes when I plug the phone in, it does not recognize that it is plugged in and will not charge. This is not an issue in itself, because if I unplug and plug back in a few times it will eventually charge. The big problem is when it is NOT plugged in. The phone will often switch between charging and not charging on the battery indicator.... even though it is NOT plugged in.
I read up on this and found that... shocker.. this is just one more issue plaguing Nexus owners. The real problem for me is that everytime the phone switches from thinking it is charging to not charging, about every two seconds mostly, the screen comes on. This results in the screen constantly going on an off and the battery draining extremely fast. It is 8:17 am, and I unplugged the phone at 6:40 this morning. In less than an hour and a half, the battery has fallen to 38% and I have not used the phone at all today. It is sitting on my desk, flashing like a disco club.
I have searched but have only found an option to keep the phone ON while charging. Is there an option or app available that will prevent the screen from lighting everytime it thinks I have plugged it in to charge? I am rooted, so any option known would be helpful.
I cannot wait to throw this thing in the garbage, but I am not happy with any of the other options currently available. I like the look of the Galaxy S3 but the Gnex has left a bad taste in my mouth for Samsung... it was my first Samsung phone and I'm not sure if I should judge the product line on all the problems I have had with this phone. I loved the HTC Incredible it just got a little old.
Can anyone help me with this problem... please! It is now at 30% since I typed the last few lines. I can sit and watch this thing draining like a bathtub.

try changing the usb port on the phone
http://www.ifixit.com/Guide/Repairi...zon-LTE-Micro-USB-Charge-Port-Main-Mic/9641/1
I had this issue caused by water damage quite recently - it was in my pocket during some absolutely unprecedented rain here in the UK, and although it seemed I could charge it without problems, when it was off the charger it'd be confused and flash on and off as you say. I just threw it in some rice and took it out at midnight, problem solved (whether the rice was actually responsible for solving it, I have no idea). Has your phone been used in the rain or anything like that, or been in the pocket of clothes that aren't very 'rainproof' during rain? Could be it.
Is it the charger? I had a bad car charger that did the same thing. If not, I would contact Samsung and see what they can do for you.

I read about the water damage being a possible culprit but I cannot remember it getting wet anytime recently. It is not the charger, it does the same thing with two different chargers and the car charger. It does actually charge, thats not the problem. The problem is when I am away from the charger the screen just comes on all the time and the battery is drained rapidly. It has been having issues for a week or two now but just recently started having the problem when not actually plugged in.
Someone just needs to make an app with an option NOT to turn on the touchscreen when first plugged in.

Have you been able to fix your issue? I've had zero issues with my Galaxy Nexus for months, and now I'm having the same problem you describe. Initially I thought it was the ROM, but last Sunday I noticed that the phone will simply not sleep without being charged. The USB port appeared to be bent downward, so I used a tiny flat head screwdriver to raise the port. This seemed to fix the issue for a few minutes, but then the phone kept waking up. It's murdering my battery, and I'd like to fix this situation. The problem seems to be intermittent, and occasionally it will work for hours at a time. This leads me to believe that the problem could be internal.
I'm wondering if you tried anything else? I don't have a problem replacing the USB port myself because it seems like an easy and cheap fix. I'm not a novice when it comes to repairing phones, but I'd rather not open the device quite yet.
The new part is $8.00 shipped, and the seller is in the US. You can't go wrong. I will report back once I fix the problem.
Not really, the problem just sort of went away a week ago... I'm getting the Galaxy S3 end of October so I'm not going to replace the USB port. I messed around with the usb thing too, bent it with a knife so it wasnt touching anything. I also tried cleaning the contacts and blowing it out with air... not sure if any of these things helped or not. Like I said if I made it worse didnt matter as I'm getting GS3 soon. So for now its working but not sure why or how or how long...

I've got the exact same issues, it's ruining my battery life. Has anyone found a fix for this yet?
Its a physical problem. You need to replace the charging port, or get new phone like me.

@calaski8123 -> how would I replace the charging port? Should I contact samsung/google?? I have the exact same issue being discussed here and its driving me nuts. And I got this phone just a couple months ago so getting a new phone is not a solution...
best,
-Nripesh
If its new I'd take it back under warranty. If not, you can buy the parts on ebay and other sites... Search the Forums here, there are details. You can also search Youtube for a guide. Samsung probably would fix but it would cost much more.
Mine is better, but not sure what fixed it. The battery still doesn't last but half a day so I'm still getting the S3 in week or so.

Gnex Charging Issue
Hi all! Yes, I am another one of the unfortunate owners of a Gnex with this issue. I wanted to send out a reply to everyone that says to replace the USB charging port. I just had mine replaced, and it did not fix the problem. I have also tried different batteries, and I have read where some people are fixing this by *** gently *** bending the USB connector up ( toward the screen ). That also did not fix my problem. A few days ago I installed AOKP 4.2.1, and that was ineffective as well. I am stumped. My Samsung Fascinate was a very good phone, but the Gnex is really making me wonder if I ever want another Samsung. Has anyone found a solution for this? Unfortunately for me, I bought mine used and don't have the option of returning to Verizon for help. Thanks!
Okay, gonna try and explain this as best I can, bear with me.
2.5 years ago or something I got a Gnex from Verizon, brand new. The phone would act like a ghost was using it, like someone was interacting with the touchscreen. It'd randomly call contacts, send texts (random letters/numbers), all kinds of weird stuff. Video of it on day 1 HERE doing this. Took it into Verizon, got a new replacement. Never had the problem again. 2 or so years go by, not a single problem, unlocked, flash, all that, never had the problem again.
About a month ago, I upgraded to a Moto X and passed this phone on to a family member. At the time was running the latest stable Cyanogenmod ROM, the last for JB. 10.2 maybe? Anyway, that's what ROM was on it, again, no problems. Factory reset the phone to wipe my stuff, left it rooted and unlocked. I gave them the phone, battery, extended battery, and a few cases as well, no charger cause I know they'd twist up and destroy the factory cable. Setting the phone up for them battery starts going low, used their charger. Cable had shorts and crap, scavenged around looking for good charger. Get phone set up for them, and I'm done, handed off.
A day later, they're complaining that the phone is going crazy, like a ghost is using it, and it's randomly calling people, sending texts, opening menus, not charging, etc. Sounds like EXACT same issue I had with my very first Gnex that I exchanged. Figured that was really strange, maybe it was the software. Factory reset to latest factory image 4.2.2, lock BL back up, completely bone stock. Re-setup phone and all that jazz. Phone's acting fine. Decided this time that'd I'd let them have the original stock charger, thinking maybe that'd help with the charging issues too. All seems well....
However, during the reset and all, and after re-setting up the phone, battery is low.... plug it in with a known good charger of mine, but not stock original, and all the sudden the phone's freaking out again. Turn screen off, turns itself back on. Dialing people, opening apps on its own, etc. Figure maybe this Gnex just won't take any charger except it's original. Pull battery, reboot, phone's fine, fine for 10+ minutes. Plug in OEM charger this time, wait a few seconds, unplug, phone goes crazy.
Also interesting, they brought another charger of theirs with a little red LED on, plug it into wall, red LED comes on. Interestingly, if the charger is unplugged from wall with red LED off and I plug it into the phone.... the red LED on the wall charger turns on... that's not right. So.... here's where I'm at now. If I pull battery, reboot, and never attach a charger, the phone acts perfectly fine. The instant I plug in ANY charger, it'll start going wacko and continue to until I pull battery and reboot. At first I thought this was a charger issue, but now... I'm thinking it's battery related. This little experiment of getting the phone to go crazy after plugging in a charger applies to both the OEM and extended battery, regardless of what charger I use.
When I owned the phone, I almost exclusively used the OEM charger, occasionally another charger I had that I know works fine. Gave Gnex to family member WITHOUT a charger, so they were forced to use who know what condition phone charger. I'm wondering if maybe some rogue jacked up phone charger with shorts in it and crap somehow killed the extended battery. Then, they switched to the OEM battery, and again, unknowingly killed that battery too with the same crap charger. So maybe buying a new battery would fix the issue and only using the OEM charger from now on or the other one that was mine that I know works? Or maybe the phone is just broken now? It just doesn't seem right that plugging a phone into the micro-USB should turn ON the red LED on the charger when it's not plugged into the wall, like the power is coming out of phone and going into the LED...
I just refuse to believe that on the exact same day and within hours of me upgrading to a Moto X and passing on my Gnex that had worked perfectly for 2 years in my possession somehow just happens to "break" or "go bad" on its own. Thought it was software glitch/bug in CM, no. Thought it was incompatible charger, no. Maybe the batteries are bad? Maybe the phone's circuitry got jacked up too? Just seems weird that, as far as I can tell, pulling the battery and rebooting fixes it for good until the battery dies. Within 30 seconds of connecting a charger, the phone goes bonkers.
Any ideas? Feel bad, family member probably thinks I dumped a bad phone on them!
Thanks!
What kind of sorcery was that? I honestly don't know what to say about this other than bad timing? I highly doubt a ghost is possessing the phone.
I know a ghost isn't possessing the phone, I just, that's how I best described it when it was going wacko by itself. Plus, interesting topic title, maybe get a few more people to read it and maybe offer some advice or info or something :laugh:
However, I do have a ghost in my house, or a spirit or something. I've seen him, sitting on my couch before. He died in a fire, smoke inhalation, no smoke alarms in the house. House was sold, completely rebuilt, and I am first to live in it since then. Crazy story for a different forum lol
From what I can see, it's just that the screen isn't working properly because of leaked currents from the battery or the charger... Just get the whole screen replaced (it's hard to only replace the glass layer) and should be fine.

Leaking currents, had it happen to me before from a bad charger. I doubt it's the battery, try an outlet in a different house, they may have bad power.

So this "leaking currents" problem, it's a problem with the battery? A problem with the phone, in particular, the screen? It definitely sounds like a rogue bad charger could have done this based on the feedback so far. The "damage" or whatever happened at their house. Just the other night, they brought the chargers and phone and stuff to my house, a different house, problem persisted. So I'm not thinking it's a dirty power issue or anything.
...and so you should have the screen replaced. I've had Motorola and HTC phones with issues responding to touches when charging, and replacing the screen largely eased the problem (although I still ended up getting a new charger because I don't want it to also damage the newly replaced screen).

Could be the battery, could be the USB cables or chargers, could be the USB port on the device, could be the screen. The fact that it only happens when plugged in but with more than one charger and battery makes me suspect the USB port on the device. From my understanding you can buy a replacement. A temporary fix would be to use a charger that charges the battery outside of the phone.

No ghost... i think
I think its because the charger you use....
I had the same problem, but not with gnx... before gnx I used galaxy i5801...
when I put my mobile in charge, my mobile did some crazy things, like operating itself,...I figured out that the charger I used is not the one I shouldn't use.
every mobile has a charging limits, like voltage restriction..
little difference in voltage could make big difference.
so I changed the charger. problem solved for me.
other than charger.. there are some things can do this, I don't know about all.
I doubt it may caused by your digitizer...maybe is has too much sensitivity, caused by water, dust, pressure, etc....
digitizer and display are not the same.
I faced this one too ( galaxy i5801) before charging problem, but not with gnx.
A digitizer is the part of a touch screen that senses your touch and "digitizes" your gestures into impulses that the phone can understand as commands.
if it continues my last suggestion.... call the priest
Well, I borrowed an OEM standard and extended battery from a friend, neither fixed the problem. My friend did say that similar to my first Gnex, when he first got his, it did the same exact thing, but after a while it stopped and it hasn't done it ever since. I also narrowed it down, or, widened the issue, in that it's not just AC chargers, the exact same stuff happens with a brand new 12V car charger.
Dirty power on the fifth rail of a USB wire. Its either the charger not supplying enough power or a damaged cable.

My vote is on the screen, due to the digitiser. Replacing the touchscreen could help solve the problem. I was in your family's position when I got a used Motorola Cliq from a friend and the battery was all good, no leaks. Ghosts just started touching it everywhere like a crazed groupie when it went into my possession. No explanation as to why it happened and I didn't look into it that much but replacing the screen is the most likely solution.
Hey,
My LG G3 battery's holding a charge seemingly well, but it isn't able to power the phone anymore, for some reason. Off the phone, I've managed to have six common DC motors and 12 High Intensity SMD LED's running for two days, to test the battery capacity, and it managed this feat with 30% battery remaining. It seems OK by me.
But after plugging a single high power DC engine, the battery kinda "shuts down", like it tripped a breaker or something, and only turns on again after I remove the connected device. Several other batteries I own (notably many Nokia BL-5C, originals and knock-offs) are able to hold the high power DC motor flawlessly. Using an amperimeter to hit the terminals, it briefly shows 1.1A before "turning off", while other batteries just keep powered, showing 1.4A, 1.5A on the display.
On the phone, I think that when it tries to pull a high load from the battery, the battery turns off and the phone resets. On a charger, though, it is able to run indefinitely. If I disconnect the charger and don't touch the phone, with the screen on, it'll most likely keep on, until a notification arrives, or when I touch the screen (probably the touch boost that draws energy)
The battery isn't stuffed (i.e. "fat"), looks healthy visually and it seems to hold a charge pretty well, so I don't think it's internally shorted... right? What's possibly wrong with it?
P.S.: I've already ordered two new batteries.

I have the same problem. The phone works only with the USB cable pluged in. Without the cable, the phone goes out to the first notification. Problem starts with the 23/12 CM13 and the 26/12 the phone turn off. I try with the solution in the CM13 tread but nothing works. Stores tell me that it is a hardware problem and not the battery. Service centers are closed until the end of the holidays. I will buy a new battery but I think it is not the solution.
Please let me know if a new battery is the solution to the problem.
Sorry for my bad english...

Interestingly enough, it happened after a freeze and discharge overnight on CM13.
I do think it's the battery, though, because it also does that in TWRP, and my tests on the battery itself showed a weird pattern of sudden shutdown on heavy power consumption. Perhaps CM13's freeze contributed in damaging the battery, but I think the remaining of the hardware is in good shape. Mine would die on the first notification if sound is enabled, because it'd die just milliseconds after starting playing the notification sound, or just at random after I remove the power cable. I'm 98% sure it's the battery, at least in my case. I've managed to access TWRP, backup CM13, wipe the system and install the new LG Marshmallow ROM, all by using the charger cable. I've managed to boot up on the ROM, set it up and restore my Titanium Backup.
From my experience, stores always lies about "shorts" in the phone motherboard. It's a inexplicable excuse that most of the customers bite. I've had a friend taht was told his "wifi card" from his G3 had "busted", and it needed a "replacement" of the "wifi module only". As you know, the wifi module is integrated in the Snapdragon 801, so that'd be impossible if not replacing the entire SoC. He asked for my help, but I couldn't reach him. Most likely a hard reset and reflash of a stock KDZ would fix his issue, but he had to take it to a "professional", which asked for a good amount of money for "fixing" it. Probably they just did what I suggested, and took his money after a lame excuse.
I could be wrong, too. Although both our phones had similar issues after 12/23 CM13's, my case can be different than yours. One thing that I was willing to try was to rig another battery (like I said, I have many from different models) to the probably damaged LG G3 battery, to see if it holds the phone. Unfortunately, just connecting a different battery to the G3 will show a "?" mark on the screen, similar to that when you plug it in without a battery. Rigging it with the stock battery would fool the phone thinking the battery is original and is running fine, but unfortunately I cannot reach the terminals safely when the battery's connected. I'd rather just wait for the new batteries to come.
Can I post your PM to the thread? It seems very pertinent.
Thanks
I have seen batteries do all kinds of stuff. Most deff hold nominal operating voltages not just on phones but all things theyll hold nominal voltage but the actuall amperage to drive whatever isnt there. Not like a dead cell where forsay a 12 volt car batt has 6 cells 3 pos 3 neg each cell a. 2 volts per cell equalling 12 volts 1 cells bad 10 volts. Now back to even though u tested the batt i would still try a cheap bat and see the g3s are real finicky on batts normally i dont recomend a cheap batt or the bigger batts i always use the oem bat
