Desire not charging :-(

Had the new phone for a few days now, I got the 'battery low' so plugged the phone to the mains charger, however...
Previously the green battery elements inside the symbol would move from right to left (indicating charging), along with a lightning flash inside the battery symbol, I now get the the lightning flash but no moving battery elements.
The phone indicates the batter is being charged but the battery is not actually taking a charge.
Have done a factory reset in case it's a software issue but no joy - looking like a hardware fault or a knackered battery (already!!) so will take back to CPW tomorrow.
Not good.....

how do you know that the battery is not "actually" taking a charge?

theres aways bound to be hardware issues with the first batch of phones released from the ware house, just the same as there will always be bugs with a piece of software. don't get yourself down about the quality of the phone.

Battery level in About Phone/Battery is stuck on red, even after 45 mins.

I agree, my 'not good' was meant more as it's gonna be a pain to get it swapped and time to reinstall apps etc. I'm an IT man so well aware of 'first batch' issues

Are you charging the phone from the AC adaptor or USB cable via your PC?
Does sound like a hardware issue, I suppose your phone will have a 2 year warranty anyways.

Both - have tried AC and USB.

Get a spare battery to check that the problem is not with the battery

Phew, phone picked up a charge overnight and is now charging correctly (not that I had to do much to run it flat again!).

That's good news. I don't particularly think the offical HTC AC adaptor chargers are that impressive. On my older phone (Touch HD), it was the exact same stock charger from HTC which I used and, on many occasions, my phone's orange LED would not come on at all and was very temperamental. The USB sync cable worked fine though when charging via PC.

mines done this now, discharged overnight for no apparent reason and now very very very slowly charging up again. Hope its not faulty as getting a replacement is going to take weeks!

Last night mine seem to be not taking a charge, it had been plugged in for at least 45 minutes and had the charger symbol on the battery, but when I unplugged it brought up the message saying low power (battery was still at 4%)
Restarted and it seemed to charge ok. Today at work charging off USB is really really slow compared to my G1.

Same charging issue here. Won't charge over USB or AC. The bolt is on the battery but the green isn't moving. The same happened last night but it seemed to eventually start charging in the night.

Same issue here. Bit annoying really, phone is getting rather warm, and not picking up any charge. Going to try a factory reset, see if it helps with my case. Most likely not, but can at least try.

having the same problem now, any chances?

Update, it does charge right now, but i got to boot with the powercord connected. Pulling out the usb cord and putting it back in makes the orange led disappear and it doesnt charge any further until i reboot with the plug in. Kinda odd.. doesnt charge that fast either. Im using rcmix 1.5 and hboot cm7

i had some wtf bug a few minutes ago. the bat showed 63% full and one our later the phone was off because bat 0% Ö_ö i have no clue why, because everthing like wlan etc. was off

Well, it seems to turn out i had an ordinary usb brick. XDA has a thread on this, but these way to restore is easier: http://android.modaco.com/content/h...com/309939/usb-brick-rickrolled-b0rked-fixed/
i'm on again

This might also be caused by bootloop, as where it keeps restarting & draining your battery. Keep an eye on that as it happened to me once at night. Woke up & phone was all warm & battery empty.

[POSSIBLE FIX] Flashing red light - dead phone/inferior USB cables

Today I had my One X happily connected to my pc, just transferring some files over by USB. Then when I wanted to disconnect it, it showed a lot of 'not getting enough current to charge and operate at the same time' messages. Dismissed them all, though it was time to put it on the wall charger, seen it's critical battery status.
Once I disconnected the phone, it immediately powered off and would not come back to life again. It was, however, greeting me with a flashing red light while on the wall charger. No matter what I tried (bootloader, long hold power button, charge it for some time), it remained completely dead.
Now I did get some new micro usb cables from eBay. Very cheap ones. Now I think these are the culprit. Apparently, while in file transfer mode, these cables were unable to provide sufficient current, causing the phone to drain the battery completely. Once I wanted to charge it, it couldn't boot to charger mode due to the battery being completely empty.
Hooking up with the original HTC cable again, it still showed the red flashing light. Exact same behavior. Until I (for the heck of it) tried to bash the power button quickly. It suddenly came back to life again and started charging again through PC.
If you find yourself in the same situation with bad USB leads (something to do with resistance of the cable?) or a red blinking light, try tapping the power button quickly instead of trying to boot into recovery mode. It might save you a postal return and a week or 3. Or your ass, if you rooted it before it stopped charging.

When I had my sensation I had this every now and then. I had to remove the battery to get it to work.. Nice to know that there appears to be something I can do to sort this out if I get this now

It was mentioned that the flashing red (or orange?) meant that the temp was too high.
Just let it cool down, and it will come back.

It definitely wasn't hot. Also, it wasn't flashing orange. Just slowly red.

flashing orange - low battery
flashing red - very low battery
It could well be the battery level is considered too low to operate. So to protect the circuit and the battery, the device is not allowed to turn on until it is sufficiently charged.

This is currently (no pun intended) happening to my one x, left it plugged into my pc via the htc usb and got flashing red light after a couple of minutes, after a couple of minutes more it stopped flashing and became a solid red light (a sign it is charging from v low battery from m experience) pressed the power button and voilà its come back on. I can't believe htc would let the device get to such a critical state of battery before powering down, can anyone enlighten me as to why it would do this?
(thinking about it i was showcasing the handset to my apple touting buddy and had 3 pretty heavy apps running, it was a couple of hours after i noticed it had killed itself so i'm guessing they were still draining away the power from the background??)

I'm having the same problem. My phone was off when i got home and it wouldn't turn on (I assume the battery was dead). When I put it on the wall charger the red the red light didn't turn on and my phone wouldn't boot. I tried several chargers and cables and also tried to connect it to my pc. After leaving the phone for a few hours (unplugged) i tried to connect it to my pc again and i got the blinking red light. A few minutes later I decided to plug it into the wall and the red light turned on and now it is working normally.
anyone got an idea why it didn't charge at first?

agree chaging cable fixed my flashing red light problem

Poor quality charging/data cable
A poor quality charging/data cable will also impact the ability to charge the HOX in your car. I have two cars, in one I was using an old Blackberry cable and Griffin charge adapter (1amp output) to charge the phone whilst using Car Dock and navigation software. After trial and error I got the screen brightness correct and the phone charged satisfactorily. I say satisfactorily because I still think any electronic device which is connected to an external power supply of sufficient electrical current should operate and charge at full spec. In my other car (1996 Land Rover Discovery) I was using a cheap ebay charging/data cable. Using the same apps and screen brightness the HOX would lose all charge over about a two hour period. With the same Blackberry cable used in my other car, no problem. Hence the cheap ebay cables are now in the bin.

The HTC-cable isn't that good too. I use a Nokia-charger to charge my HOX. Charging is much quicker. Maybe the HTC--charger (and cable) was crappy but i never touch them, i use the Nokia charger and dito USB cable.

Thank you!

thank you! Thank you! That cheap usb was totally the problem!

Small update.
This problem just happened to me. 1 cord gave me flashing red while plugged into the wall and pc. I switched to my other cable and its charging and functioning normally. Cord was the problem.

I had a similar issue with my one x.
It discharged completely, then when I went to charge it I just got the red blinking light for ages. I left it charging overnight thinking the battery was so low it needed a while to charge enough to be able to switch on.
But in the morning it was still flashing and the phone was very hot, so I thought the battery was blown.
So I came on here and saw a suggestion about holding the power button and the volume down button. It went to the boot menu and said there was not enough power for a factory reset or something, so I selected recovery. I then got a warning icon and the phone switched off again, but this time with a solid red light. A
After a while I was able to turn it back on again.
Hope this helps.

Wellllll
I have the HTC One VX. I know this isn't in the same topic, but since I found the thing that helped/worked here, I thought I should share my experience. So I bought my new phone on Sunday, so it is roughly 5 days old...not even a full week. I charged the phone before I went to bed to roughly 80%. I made sure all apps and what not were turned off and pressed the lock button. I woke up in the morning and checked my phone to see what time it was. Had 78% battery left. I left it on my dresser for roughly 2 hours and when I got back from class, I grabbed my phone to check if I had any messages.
The phone didn't turn on and I didn't even get the flashing orange/red light. So I tried charging it and nothing. I changed wires and nothing. I frantically searched the internet and stumbled upon this forum/thread. I tapped the power button at least 15 times consecutively and the phone barely flashed orange. I tried to plug it in again and rapidly pressed the power button 10 more times and the screen finally turned on. It started charging and I checked the battery life. Somehow, in 2 hours my phone drained itself of 78% battery life when it was on the lock screen (its also set to lock after 15 seconds of inactivity) to the point where it couldn't even turn on.
The phone/battery was not even warm/hot or w/e. It had not touched any water. No idea what caused the immense power drain, but glad it is working. Thank you so much for this help

woops, wrong thread

It happens to me allso in this morning, in my opinion is like this: The phone is turning off when basicly you have a little bit batt (lets say something around 5% max) and its turning off to protect data and is showing to you batt empty. Then it cames a user with a charger connected to a power supply (house charger,car charger or directly to pc's usb). You must use a good usb to micro-usb charger (the original ones are't good usb cables) try to use a Nokia usb to micro-usb cable, This was the first problem most usualy. The second one is to pay a HUGE attention to UC, don't uc'it so much because then the charger board will not charge your batt so well. Keep yours HOX safe and anjoy it. Have a nice day boys and girls.

Not Charging After Full Drain. Not Turning On When Plugged In

So I'm having a problem where I drained my battery and the phone shut itself off with 1% to 2% battery life remaining. I've left it charging for a good 45 minutes now. Turned it on, and it reported 1%. Thinking that it was just a reporting error, I unplugged it, and the phone promptly shut itself off. Now another 30 minutes has passed, unplugged it, turned it on. The phone refuses to turn on! It will however show the battery charging animation, so I know it's not bricked or anything. I guess my only solution is to leave it charging while it's off overnight, even though I need to use my phone right now... That important person will have to wait :crying:
Edit: Works again... Though it does not show my battery life correctly. It says 15% when it's probably more like 2%.

Might want to use a different cable.. i have read that the cable and possibly even the wall adapter can be flakey.. if you have a spare cable try to use it instead of the lg one..

Original LG cable is fine. It's ever since I drained the battery it's started to act weird. I plugged it in at 3% in hopes of "calibrating" the batterystats and it was charging fine. Up till now. I caught a glimpse of my phone turn itself off while charging.
Now it's randomly decided to turn itself on and bootloop... And back to charging animation while off we go. What the hell? The battery isn't charging... Switching cables didn't help btw.
Found a third cable. Temporarily working..

Hmmm maybe the charger? Sounds to me like its not getting proper power hence the shutting down while plugged in.. but what do I know heh

I have the same problem. Plugged the phone in at about 3% and walked away. Came back an hour later to find it stuck in a loop of the LG logo and a black screen. I can sometimes get it into recovery, and from there see that the battery percentage will go from 0% to 15% and back to 0%. It's like the battery is bad.

I think it's a problem with the ROM/firmware where we can't drain it and hope to charge it up again..

I'm still running v1 of the jb release and last night I used my phone until it shut down at 2%, charged it up fine, and its been ok, knock on wood. One weird thing is that if I use the phone while on the charger, and I mean light tapatalk usage, the phone will drop to 99%, even while plugged in. Weird.

That's normal. When the phone is charged at 100% it stop charging to avoid the battery to be overcharged thus reducing it's durability.

Not charging again... My phone maintained a charge between 10% and 25% or so according to the battery usage graph. So I switched cables again. I went into the service menu and got a screenshot of the charging test this time. First pic is with the LG cable. Second is with a Samsung cable. Third picture is back with LG cable after the battery successfully got charged past the "low battery zone" with the Samsung cable.

I have a similar problem with the stock charger. After a few weeks of working perfectly, it just sopped charging my Optimus G.
Bizarrely, it charges my wife's Galaxy S2 HD LTE without issues.
And the charger from my Sony-Ericsson Xperia pro charges the Optimus without issues.
It's almost like the stock charger burns out something internally such that it doesn't output enough voltage/amperage/current.
Sent via the magic of an Optimus G (E971) running CM 10.1.

So it happened again... But this time, it occurred in between 20% to 40% battery life while charging. It's probably the LG cable.. Gonna call support and ask for another.

I have a similar situation -- I powered down my phone one time at 5 %, did not wake up until one hour of charge, then last night tried again with about 40 % of battery left, same problem. I was wondering at first if the phone did not go to power down properly, and that the battery would drain through that, but then I just did another test with my battery at 30 %, and the phone did not want to restart until plugged in for 5 minutes.. It's almost as if the booting process is just this huge battery drain, sucking all the juice to start the phone in a peak of electrical rage.. anyway -- I noticed that yesterday, I was trying to restart the phone after a while, it would start to boot but it seemed it owuld just miss a little bit of juice to complete the process, then finally when it made it to screen it was at about 10 %..
Could it be that fix we used in the stock rom to get the screen at more than 65 %, and the cpu at 1512 mhz ? It seems more software related than hardware in my case, meaning I don't beleive it is the cable

Hate to revive an old thread, but as the new owner of an LGOG i just ran across this problem the other day. My phone has been able to go two day on a charge, and last week I forgot to charge it on night. Found it dead the next day. was leaving so I took it intending to charge at work or in the car. Car charger had no effect, but upper portion of phone got hot. plugged it in at home, same thing, charging icon, getting hot, but not charging. Also noted dim screen glow all the time.
tried 2o second hold on power button, vol up and down, got into the download screen and the bootloader screen, but no charge. Finally held the power button and vol. up and red charging light came on. Held it for a minute and the red charging light stayed on, let go out it went. Decided to try a couple of rubber bands around the phone to hold in the buttons, and it worked ---phone charged fully and operates as usual.
Thought I'd pass my experiance on to help anyone else with similar problem. Any idea why this worked?

I don't know, but I do know that getting to android 4.3 roms like the ones in Houstonn's thread have cured my O. G. from that, and from also constant and random camera reboot, and from also maps freaking out when plugged in in the car..

For anybody that runs into this problem
I had this problem and tried for hours and hours to fix it. When you stick the usb charger into your phone, it literally takes like 5 hours to charge 2% when it's in this state
So it never gets to a point of wanting to turn on because the phone gets too hot trying to charge
My solution: Put a bunch of ice in a bowl, then put something over that like a bag, aluminum foil, basically anything that would be a barrier between the ice and your phone to keep it from getting wet
Now let it charge with the phone sitting on top of that ice for a few hours(make sure to add new ice as it melts) and your phone will charge up enough that it can be fully turned on. Then just let it keep charging
This worked for me after trying other things for hours. If this didn't work i was gonna open the phone and pull the battery

After the last update I have not had this issue. I've run my phone dead a few times and now it always charges - no issue.

Last fall. I had to go to the stock rom, do the update, reroot, then all was fine.

[Bricked] Flat battery, Won't charge, No recovery, No root

Hello all,
I'm at my wits end to put it lightly... I have the P-605, I was trying to flash ng1 official firmware through Odin v3.09, which the file in question, I have used a few times before so it isn't a bad download.
It got about half way through and died. The tablet still boots to the 'firmware upgrade has encountered an issue screen', I can still enter download mode. One major issue I can't charge it and i have no recovery [emoji22] its now dead flat.
Even with my 2.1Amp tablet charger it boots for a few seconds and dies. I've tried multiple cables and USB wall chargers as I thought that may be the issue all to no avail! I am completely lost. Any help would be muchly appreciated

What was the firmware before you flahed the stock ng1? cm11?
Have you try to flash recovery with Odin, don't let it boot up and see if you can boot into recovery.
Did you try to flash with low battery juice??

The prior firmware version is unknown :-/ but it was X KAT v3. I did try to flash recovery but it resets before it gets it done, if I hold the PWR, VOL+, HOME the screen seems to light up stay black a little longer than if it was going to the firmware issues screen then go to 'firmware upgrade has encountered issues' screen. It seems the longer I keep it off charge the longer it takes for it to reset next time its plugged in, so I will leave it for a hour and try to flash recovery. I didn't know what the battery was at 'probably very low' as I haven't used it in yonks and it was already in a bootloop from flashing X Kat v4.0 incorectly otherwise I would have charged it

I'm thinking about taking the battery out and manually charging it with a old USB cable. From pictures on the internet the battery has 2 red 'positive' 2 black 'negative' and 2 green. I'm unsure of what the green cables are. Is there anyone that can shed some light on this?

Hi,
have a look here for the USB pinout !

The original cable uses only four of the micro usb pins. The second ground pin is missing. This can be used to put the device into certain modes. I used different cables, all with five pins, no problems, but it does not mean, that the fifth pin was wired in these cables. Batteries have an internal security circuit which cuts power vis a polyfuse, if the voltage drops too low. The fuse should be re-armed when connecting the device to the charger, although the device may not recognize its own battery. Let it charge for a while, that the fuse doesn't blow again when disconnecting. Plug in again to charge fully. Some devices have a design fault which makes them unable to recover with a discharged battery. Charging Voltage is not 5, but 3.7v! The additional cables at the bsttery are either for a dumb temp probe, or a bus to communicate with the security circuit. The latter maybe impossible to charge externally. Otherwise you probably need some professional charging station, which can handle all sorts of Nimh and LiOn batteries AND have to make an adapter for the custom battery plug. Too much hassle, right?

I'm thinking about taking the battery out and manually charging it with a old USB cable. From pictures on the internet the battery has 2 red 'positive' 2 black 'negative' and 2 green. I'm unsure of what the green cables are. Is there anyone that can shed some light on this?

Get one of this usb filter charging adaptor and use your pc to charge it. This also allow you to charge your tablet using any power source like PC, car charger etc... you will not see the X mark when using your pc to charge.
http://www.amazon.com/gp/product/B007IXBTCK/ref=oh_details_o02_s00_i00

This adaptor adds Apple signaling for charging currents above 0,5A. If the current charger won't support Apple stuff.
And yes, I suspect that the Note expects the Apple signal for 2A iPad charging.
I don't know whether there are any supported charge modes in between, like 900mA, but it charges from a standard 500mA usb port, but only in soft-off and idle deep sleep, and ultimatively slow.
But then, since the KK update, some people's Notes charge only during active state.

HELP

Hello all,
I'm at my wits end to put it lightly... I have the P-605, I was trying to flash ng1 official firmware through Odin v3.09, which the file in question, I have used a few times before so it isn't a bad download.
It got about half way through and died. The tablet still boots to the 'firmware upgrade has encountered an issue screen', I can still enter download mode. One major issue I can't charge it and i have no recovery [emoji22] its now dead flat.
Even with my 2.1Amp tablet charger it boots for a few seconds and dies. I've tried multiple cables and USB wall chargers as I thought that may be the issue all to no avail! I am completely lost. Any help would be muchly appreciated

I have the same issue.........!!!
I'm lost at this point and dont know what to do.
Any attempts at flashing appear to be useless as there is now zero battery and it wont charge.
It boots straight to 'Firmware encountered a problem screen'. I can get it to the download screen.
It also made it 47% of the way through a recovery via kies, but i think the battery issue caused the failure.
If the cable is pulled out while in the firmware encountered a problem screen it instantly dies and wont start. It wont start unless the plug is in........

Anyone??? Please???

With zero battery, you can't perform any maintenance requiring a usb connection.
Without OS and/or custom recovery, i don't know any advice.
ADB and probably Fastboot operations can be performed via wifi, while the thing is at the charger, but in brick state this won't help.

Thank You
Advice to is find a way to Charge the battery then attempt other methods.
I think Kies may work if I have Charge
Cheers

Maybe the Note froze and drained the battery till it's safety circuit kicked in.
Then you should leave the Note charging for a while(hopefully), to reset the circuit's fuse and get enough juice to not trigger it again immediately. Normally, after unplugging and replugging, the battery should get recognized again and charge normally till full. Monitoring charge in Off-State requires(only) a working kernel, i think.
It also could be a defunct usb jack or just the connection with the main pcb is loose, which is typical for the Note, like loose display and backlight cables.

Thanks Lecorbruiser.
I have had the unit aprt a few times to verify battery connections and all ribbon connections on the boards are ok.
Im note sure of the safety circuitry uou mention though.
I have also power the device up with out the battery plugged in at all. So i know the supply is there. Maybe i have run the battery too low to recover?

The safety circuit is in the battery or attached to it. Once its fuse has been triggered(normally at 2,5v), the battery shows zero voltage & open circuit. Current from a charger should reset the fuse and the battery will charge unless it had been discharged below 1,5v.
Normally devices with 3,7v batteries are shut down by the system at 3,5-3,0 volts, mostly 3,5 like the Note.

Well the device started to flicker and couldn't keep the screen back light on when it go low.... I'd say I have trashed the battery then if it got below 1.5?!
I have left it on charge for over 10 hours a couple of times and achieved nothing

Android shuts down at 3,5v, in case of a freeze(which could go unnoticed if it happens in standby) the circuit at 2,5v. Then it's a matter of self discharge, till the battery reaches the critical point of 1,5v.
The flickering backlight denotes one of the other cables running across the battery, like that for usb.
I think the connections loose by holding the note in your hands, pressing on the backside. A case with a stiff back will stabilize the Note, like mine. Otherwise all pressure goes thru the flimsy back and is applied on the battery, the metallic shields or some spacers. And the cables get bent very slightly during pressure. Should be harmless, but seemingly isn't.

I have done some testing... here it goes:
Battery Voltage disconnected 2.69V
Battery Connected and USB connected 2.8V
Battery not connected or ( after accidently) shorted 1.5V
From my reading android min voltage is about 3v?
Normal voltage from 3.7v to 3.2V and Charging voltage at a max of 4.4V
I also see some talk of 2.7V figure as a minimum cutoff point, this maybe why it will not give 4.4V to charge as below 2.7v maybe considered a write off?
Thanks for your info lecorbusier

With some custom roms, but none i know for the Note, you can modify the shutdown voltage, to squeeze out a couple of minutes battery life, though the voltage goes down rapidly after having reached 3,5v.

SM-T320 Issues, not charging at all

Okay, so I installed CM13 sometime in April I believe. It was working fine for the most part, battery life wasn't any worse than stock, and I couldn't do OTA updates and had an early nightly build on it.
A couple weeks ago, after my kids let the battery deplete all the way (again), I plugged it in overnight. I should add that when the device was being used while charging, it would get VERY warm at the USB port. The next morning, when I turned it on, it flashed the Samsung boot logo, flickered a bit and shut off. I tried going into recovery, looked through these wonderful forums and even re-seated the battery. It would showed the large empty battery symbol once, sometimes boot the Samsung logo again but always flicker and shut off in about 1-2 seconds. This happened about 3-5 times. Now it doesn't do anything at all.
Before I drop any funds on a battery (I'm on a very tight budget) should I try anything else? Should I be thinking of changing the USB port instead?

try another 5v 2+A charger and micro usb cable

I know that once my battery is completely depleted, I had to re-seat the battery connection cable, then I plugged the tablet into my PC for about an hour and got that same battery symbol with a circle indicator. After the hour passed, I plugged it into a standard Samsung charger and let it charge from the adapter fully. This has happened to me a few times and the above method has always worked for me! Good Luck!

I'll give it a shot, thanks! At the very least, I know the USB port is doing something since it gave me a quick battery/circle indicator after I plugged it in to a plug charger this time!

Well, it took about 15 hours of being plugged in to fully charge, after bring plugged in for a full day just to get it to power up at all!
So now that I can turn it on and stuff, it's getting VERY warm to the touch. I do remember it getting warm before, but never this warm. Right now it's not in it's case, which might have hidden the heat before.
It's mostly on the left side of the device where the heat is most intense, right about at the middle of the device. Is this a signal of the battery needing to be replaced?
And thanks! :good:

Glad to hear you got the device to come back to life, but in regards to the battery... I've always noticed the heated area in the center left side of the device when multi-tasking. Personally, I flashed a CyanogenMod Rom and have seen less heating issues than when I used the standard TouchWiz Roms. I'm really trying to prevent my tablet getting to the point of a battery replacement, but the Rom seemed to make a difference for me.

The cpu/soc is in the bottom middle (when device is held landscape mode), it will get warm / hot depending on what tasks the tablet is doing, under idle conditions it should not be hot, turn screen brightness down too, when charging it should get warm near the usb port and maybe slightly warm on the back but not hot.
