I've got an alternating orange/yellow LEd thing going on here, no notifications.
Temp is 118F. It's on the USB charge using wireless tether.
I jsut stuck it in my window, temp went down 2 degrees, and the notification flasher stopped. It's back to just orange for charging.
BatteryTime Lite may have just saved my phone from frying.

Turn the screen off when your using wireless tether and make sure it is charging with a wall charger not usb. This will keep the temp down. The lights are a warning that the battery temp is over 48c. I have a cradle to stand it on its side so it stays cool and the lights never come on if you do what I stated.

Perfection, thank you!
If I remember correctly C=(F-32)/1.8.....which means you were at 48 degrees F..Mine has only thereone time and battery information was telling me it was overheating. Quickly turned off and removed battery and put battery and phone in front of fan. I don't remember seeing my led flashing
Only bad thing about wireless tether is the phone gets hot quick if you are downloading or viewing pages that have a lot of animations or video. I usually use mine when I'm in my truck away from home. I just started putting it in front of an air vent with the AC on and the battery cover off. Keeps my battery at 26.4 degrees Celsius. I also just started working on a mod for the battery cover to house 2 very thin fans in it to pull air off the battery.
HTC phones require a lot of current to charge compared to most phones. If you plug it into a USB port it might not hold a charge while using wireless tether. Only wall charges meant for HTC phone are recommended because of the high current needed. Also using a wall charger designed for HTC will charge your battery in about an hour. I have an inverter in my car with USB and my phone charges from 15% to 100% in 45 minutes.
Yeah, USB and charging while using wireless tehter slows the drain, but it;s not enough to hold my charge or add charge to it.
I was at 118 degrees F, idk what it is in celsius, around 40+ or so...
I have this grey usb cable for my wall charger plugged intot he htc adapter and it charges nice and fast. Only have my phone on the computer for adb right now./
Dude I used to get that all the time get a little like desk fan and just sit your hero in front of that if your charging while using WiFi tether make sure its actually blowing on ya phone though like sit it on some. Cd cases or something like that
A friend of mine just picked up a Droid X today and he's having problems.
First, the charger it came with doesn't appear to charge, there is no charging indicator light.
I attempted to use a number of USB chargers, the first from my HTC Hero, another from an iPad, and a third is a cheap Chinese AC charger with a USB port that I picked up for my EVO.
The only charger that turns on the green light on the top is the cheap Chinese one.
If I plug it into my computer, I can also get the green light to come on, but it doesn't appear to be charging it. When the phone is on using the cheap charger, the phone appears to work, but says on the lock screen to plug the phone in.
Further, the lock screen is not responsive. We let it charge with the phone off for about a half hour with the green light on, the phone boot up and had a little bit of life and the screen did work, then it suddenly turned off and won't boot past the Motorola logo (just flashes for a couple of seconds then disappears.)
So, whats the verdict? Hardware problem or is anyone else experiencing this? The phone did completely die, so I wonder if that caused a problem of some kind.
Do you have a Green light when charging with the phone off? Does the light flash red when it's on and charging?
Thanks for the help!
I plugged it into my home computer and nothing happened vs. being able to charge my computer and nothing. Although the phone was about half way charged before I plugged at work, vs 10-15% at home.
Mine didn't charge while plugged into my netbook, but does charge while plugged into my PC, and definitely charges while plugged into the wall charger.
Update: After using the wall charger and fully charging it, I connected the Droid X to my computer and it now syncs up. Maybe the amount of battery power matters?
I don't think the green blinking LED is a charging indicator. Mine charges without it....but I notice when I was charging it the first time, it was going off when I had an unread text message. Is everyone sure the green LED is supposed to be a charging indicator? Mine's charging right now according to the bar on top when I turn it on while it's plugged into my computer.
I'm having a charging issue with my car charger.
When I plug it in to the car the audio volume drops to almost inaudible and the voice commands don't respond anymore.
This is with all the volume sliders set all the way up.
I have to reboot the phone in order to get it to work again.
I've charged it connected to my PC at home and work and it works fine with those.
Wow, the OP totally describe my problem i had too. I went back to Verizon and got another battery. My first battery wouldn't charge above 50% and the second came with 80% and we tried charging it at the store and it never went higher than 80%.I read on another forum that the charging indicator only reads at every 10% intervals, so that may be the problem. The rep and I at Verizon was watching it to see if it would move up to 81% so we would know it was working(beside the bubbles moving animation) and it didn't and we gave up, I will see what happens when I charge it tonite with the AC plug for the first time.
So the green LED light is not a charging indicator. Apparently, there is no charging indicator at all.
We left the phone off and plugged in with the stock charger, no light, but it did gradually move up.
I did some searching on the Motorola forums and another user ran into the same issue, he said that leaving the phone off and charging it for an extended period of time solved the problem.
I have no idea what the green light meant when it was plugged into my cheap Chinese charger, it must have been nothing.
It wasn't a text message or any other kind of notification since it was on only when the phone was completely off.
Before he left with the phone it was up to 90%. A brief press of the power button brought the phones battery state up, but didn't boot the phone.
Hope this helps anyone else with issues. Just plug it in and let it sit overnight.
I had a similar issue the first day.after overnight charge all seems normal for day two.

The only charging indicator is the lock screen part if you just turn it on it will tell you at what point it is charged.

It will occasionally show 5% intervals when it gets below 20% (I've seen 20, 15, 10, and 5% intervals).
I've noticed my phone doesn't like charging from a computer while the battery is really low. Once it's had a little bit of a boost from the wall charger, it will charge fine off the computer.
I just changed to a new one today.a friend of mine is having the sand issues. As so did i. It seems its not the battery its a short on the ground on some phones. Its pretty awkward but it has only been a handful from a batch of thousands that were released. So were in good money.

Is this good or bad?
I have no problem my phone charges fast and the battery lasts forever, my problem is i have dead pixels and they seem to be increasing the longer i have the phone, sucks that i have to wait on a replacement, i hope i don't end up regretting this purchase

When you said charge fast you're referring to wall charge? Car charge? Or usb charge?
Stock X
Hey guys,
Figured I'd swing over here and give this a bump for a buddy of mine. Seein if this may be a slightly common issue.
The situation(for him): All on stock phone NO ROOT
- No charge on wall/home charger. Shows charge indication but does not actually charge whatsoever.
- No charge using PC usb cord to charge.
Again everything is stock and not currently running any app killers or really anything out of the ordinary as I can tell. The only thing he has purchased and is running that I am aware of is Launcher Pro. The issue has been brought to the attention of Verizon which is his carrier and he just received his 4th phone! Honestly thats the only reason I'm posting an inquiry into this hear. A simple google search results shows others with similar issues(posted link at bottom). He has purchased a new battery and wall/home charger along with another USB cord. All 3 phones he has had produced the same issue with all of the charge accessories(4th phone just received so no tests as of yet, but i put money on it doing the same thing). Verizon has been willing to replace every phone so thats not a problem but seriously! Is that the only answer?
any help is appreciated in advance

There are two charging indicators, no lights! One is on the status bar, you'll see a lightning bolt through the battery meter, and on the lock screen it will say charging as well with a %.
Absolutely, yes sir. Both indicators(lightning bolt in battery, and battery charge indicators) light up and show charging. Although once phone is unplugged it will keep whatever the charge level indicates for a random amount of time usually between 1min-15mins then the battery indicator drops immediately and shows an almost dead battery. As in charge shows 80%, unplug and within mins phone shows 10%.
Also:
- There are no other indicators of charging other than those mentioned (as it should be).
- The phone connects to PC just fine for mass storage. Files transfer with no problems.
thanx again!
So... which one is it? First you say no indicators, and now there's indicators but it just doesn't hold charge. is VZW replacing the phone or the battery? sounds like a bad battery to me.
My apologies you are correct *edited post* i meant to say it does show charging as in you see the lightning bolt and everything even the battery icon fills to show a "fuller" battery although that stat drops almost immediately after unplugging.
As in replacements they replace the phone and battery as well. I know its the 3rd phone so far with the same problem.
Guys, I'm hoping someone familiar with LiPo battery charging can give me some insight. I've done some diagnostics, and I'd like your take...
- Nexus 7 3G, purchased a few weeks ago. 4.2.1, not rooted, stock charger and cable
- Battery life seems good, fully charges and discharges 'normally'
- I usually charge with the device powered off (ie: blocky battery icon in the middle of the screen).
However....
- On two occasions now, I've left it on the charger for a long time (>15 hours) and have come back to a dead device.
- Pressing the power button doesn't bring up the blocky battery icon.
- Holding the power button for 30+ seconds brings the device back back.
- It has otherwise never failed to boot properly during normal use.
Out of curiosity, I was wondering if there was something wrong with the charging process causing this, so
- I plugged the stock charger into my Kill-A-Watt last night to monitor the charging current.
- Even 8 hours after the device finished charging (via the blocky icon), the current never dropped to zero - it stuck around 10mA on the AC side (ie: ~1.2W).
- My first N7 (sent back for a bad speaker and dead pixels) went to zero after charging. My iPad does the same.
QUESTION(S):
I know modern LiPo batteries have internal circuitry to prevent overcharging, but does it sound like that circuitry might be defective on mine such that I should be worried about overcharging? Could that be the reason for my lockups?
I really don't want to go through the return process again if I don't have to. I'd rather just live with it if I can prevent damage by taking it off the charger when complete. Thoughts? Opinions? Have any of you done this test, and if so, does yours go to zero?
Thanks for any insight!

That might be a possible cause... Leaving any device plugged in the charger for long periods of time is not recommended. Anyway have you tried charging the tablet with another charger with a higher output? If it refuses to turn on even after holding the power button for 30 seconds you might be able to "wake" it up by using a higher output charger. Thats what I did on my Nexus 7 when the battery level went too low.

Hmmm...everything I've read has indicated that Lithium Ion/Polymer batteries can be left on a charger without damage since they have internal circuitry to prevent overcharging (although I realize a constant topping off is probably not wise in the long run). As for a charger with a higher output, I thought the stock charger was 2.1A....I've never heard of a 3A or 4A USB charger. Can you clarify what you mean?
Also, as I said, on the two occasions it has locked up, holding the power button has brought it back, so I'm not really asking about how to get it back if it locks up - I'm asking if the behavior (locking up, charge current not dropping to 0) is indicative of a battery that has faulty overcharge protection.
Thanks though!
The "charger" IC inside the N7 not only charges the battery but at the same time powers the device - it should allow use of a N7 with no or a faulty battery. I've never looked at the standby settings on the N7 but I would suggest that is where your 1W is going. The only info about the IC I know is http://www.summitmicro.com/prod_select/summary/SMB347/SMB347.htm
Added I think this is an identical TI version of the chip http://www.ti.com/lit/ds/slusaw5a/slusaw5a.pdf

Thanks - that's good info. However, since I have been charging with the device off, it would seem to me that it shouldn't be drawing any standby current...unless just the act of charging puts the unit in a form of standby. It also still doesn't explain why my first unit went to 0A a while after charging completed, while this one doesn't. I'm now wondering if I may be looking at roundoff error. The resolution of the kill-a-watt is .01A - which is what I'm seeing. It could just be that both units drew some current after charge completion, but this one pulls marginally more.
So, my question still stands. Does anyone familiar with LiPo technology know if this sounds like my overcharge protection circuitry is faulty? Is it normal for a device that has completed charging to draw SOME current, and if so, how much? Would someone else with a Kill-A-Watt be willing to try this and let me know what you see?
Thanks again for the help guys...
Just in case anyone is still following this thread, I have some new info. I charged my N7 last night POWERED ON.....and after charging was complete, the AC current draw went to 0A. I'm starting to wonder now whether the 1.2W constant power I saw when charging powered off is the power needed to keep the charging circuitry alive while the tablet is powered off. When the device is powered on, maybe this circuitry is running off the battery allowing the AC draw to go to 0A. I have absolutely nothing to support this, so it's just a guess/hypothesis, but at least I know my N7 is behaving the same as my first one. I also loaded Simple Battery Logger while doing my last charge and all looks normal....it charged up to about 4.208V, indicated 'full', then the voltage start dropping off - which tells me that it stopped charging. It also maintained a temp of about 23C throughout the process. I'm running a battery test right now and it doesn't seem to have been damaged by my overnight charging episodes...if anything, the battery life is better than when I first got it.
I'm going to let it go here and assume all is well. If anyone does any experiments with theirs, I'd be interested in seeing the results.
Thanks again!
I'm on the latest cm nightly,
I always let my tablet die before charging but this time something odd happened. When I would plug it in the white battery that shows its charging would come on then turn off. If I unplugged and plugged in again the exact same thing would happen.
While plugged in I would try booting up. It would get to the lock screen then power down because it had zero percent charge.
I figured out if I just kept unplugging it and plugging it in again and again after the the screen turned off while the white battery was showing it would charge some, boot and stay on charging correctly.
This is the first time this has happened....

Sort of reading between the lines here, and I've only had my N7 for about a month now...
... but mine has never shown the battery display continuously when it is shut off but chanrging on the AC adapter. It comes on for a little while, and then shuts off - but the unit is still charging so far as I know.
Mine was sitting at 59% right now, so I shut it down, waited 30 seconds, and plugged it into the charger. The black and white screen shows up, changes once or twice, and the screen goes dark after about 13 seconds.
I don't take that to mean that it is not charging - it takes some juice to keep the screen lit, so the battery will charge faster if the screen is not lit.
I guess I usually leave it booted while charging, but I can certainly shut it off and verify that it is indeed charging without showing something on the display.
I think it is a bad idea to run your battery all the way down. Li-Polymer batteries do not exhibit memory from partial charging... but they DO have a safety circuit that disables charging if the battery voltage goes too low. You are not gaining anything by running it all the way down, but are risking the possibility that the safety circuit will flip and permanently prevent the battery from charging. (The low-voltage trip circuit is there to prevent chargers from attempting to charge a battery that has a short - that would be a fire hazard).
cheers
[ Edit ] I powered my N7 off at 50% battery, plugged it in & let it sit for 40min, and then booted it - charge now at 74%. The charging indication on the screen was only on for the first 15 sec. Dunno if you are saying something different - but I don't think the charging indication is supposed to stay continuously on while charging. Too bad the N7 doesn't have a small LED for this purpose.

Hm. I remember the screen always staying on when charging when powered off. But that could be just bad memory.
I still don't understand why it would power down after it booted up connected to my charger. (this is after leaving it plugged in for about 5 minutes turned off)

pretty much all modern electronics don't allow a full charge or discharge.
I have fast charging enabled. I forgot to charge my phone last night and put it on the adaptive fast charger this morning at 0809. It was at 3% when it started. It's 0958, and it's at 22%. The phone has been power on during this time, but it should be faster than this. The setting for fast charging is checked.
Is there an indicator letting you know fast charging is engaged? I thought he gave a notification when fast charging is on. I know it worked once, and I saw one.
That strange
It only take 30 mins to charge 50 percent
Make sure you turn off all service and turn on power saving or shut down your phone
When I plug my note 4 in to charge a notification shows saying fast charge mode enabled (or something along those lines)
And it appears to charge really quick, I can't be exact on time, but my fine was down to 15% last night before I put it on charge, must have been about 15 mins and it was about 35%
Once I think it charged 20% to full in about 50 mins

That's what I thought. I thought I was imagining things when it didn't appear or maybe it only appears upon first use. I even thought maybe using Nova was some how suppressing the message.
Given you response, I thought maybe there is something wrong with the power in the computer room, so I took it to the kitchen. Then, the status message showed saying fast charging is on. Weird. So, I went back to the computer room and plugged it in. Now the message is starting to appear.
I guess the adapter glitched and was stuck in lower power mode. Not sure. Any way. Thanks for confirming the status message. It seems to be working now.
While my charger seems to work fine. I have noticed it wont pull more than 1000 ma at any given time. I was under the impression that when my battery is below 50% i should see fast charging at a rate over 1000 ma? I get 1000 ma off any decent tablet type charger, including over 50%. Yes fast charging is enabled and detected when the phone is connected to the fast charger.
Anyone else seeing this? Using "Galaxy Charging Rate lite" from the app store. Is there a better app that you guys like?
UPDATE: on a 2A 5v charger I will pull down average 1800ma when the screen is off, then it drops down as the screen is off. So, more testing is needed on the fast charger, I think I need a application that will log the ma draw at intervals to see what it pulls during "fast charge mode" with battery < 50% on the samsung charger.
Fast charging mode only works with screen off!
Charging at 9 Volt and around 1000ma
With screen on the fast charging mode goes off an charging goes to normal mode at 5 Volt and up to 1800ma.

I'm sure I read somewhere on XDA it also only works from 0 - 50%.
Going from my own experience, when I plug it in, I definitely see the "fast charging enabled" message appear in my notification bar.
However it's anything but fast. Mine has never charged faster than average speed that I have noticed, but then I rarely dip below 50% if I can help it, so that might be why.
Last night I put it on charge at 1am (at 59%), came back at 01:48 and it was on %93. Is that good? You tell me. It doesn't seem it. Perhaps my expectations are too high.
One thing I was always curious about is would it matter if you use an extension lead as opposed to plugging it directly into the mains. Not sure how much voltage it is able to draw though an extersion lead, but as must of them are supposed to be up to 240 volts, I'm guessing that wouldn't make a difference.

Are you sure, I go from 5% to full in around 80 minutes with device on, is yours faster switched off?
On my Verizon Note 4 phone running Android 5.0.1, if I go to settings/battery, there is a setting for Fast Charging which you can enable if it is not already. Just below that, there is a status message that when the phone is plugged in will tell you what kind of charging you are doing. I just plugged it in with an Adaptive Charging unit and the status said "97% Adaptive Charging" indicating my phone was 97% charged and was charging using the adaptive (fast) charging. When I unplugged it and plugged it back in with a non-adaptive charger, the status changed to say "97% - Charging (AC)" indicating it was charging but not "fast" charging.

If your USB adapter is plugged into an AC outlet or a long AC extension cord that is plugged into the AC outlet it makes no difference. However if you were talking about a USB extension that plugs into the adapter and extend the length of the DC USB cord that will make a major difference.
