I've noticed this happening any time I tether via USB or use GPS navigation while plugged in. Even though I'm connected and charging, I slowly but surely discharge. This weekend I used Google Nav for 2 hours and lost 20% of my battery while charging! On Juice Plotter, I notice the green charging glow at the bottom is a more transparent shade of green (as opposed to solid green when solely charging). Any ideas what causes this or how to avoid it? It seems to be recent.

Let me guess, you're charging off a USB port in your laptop, or using the data cable that came with the phone in your car charger?
Not all USB sources (or cables, for that matter) are created equally. Most PC/laptop ports put out 500mAh, half of what the Evo is designed to take (the factory AC adapter, the wall plug, is 1000mAh, aka 1amp).
Since it's only getting half the draw it can't quite keep up with how much power you're sucking away from the battery. This is usually only present when using the device heavily, such as with the screen on and GPS or WiFi/3G actively running.
The charging indicator (at least on Sense) indicates if it's getting the full "AC" charge (1amp) or if it's getting a reduced current charge. Sounds like that's what you're noticing.
My wife's Samsung Moment charger is 700mAh/0.7amp, and it can keep my Evo steady during use (it's powering it for 3G+WiFi tether right now), but it doesn't really charge fast at all, basically it just keeps it from depleting.
I've been meaning to try one of the USB Y-cables that join 2 standard USB ports to one female port for combined power of 1amp, but I'm not sure it will work as I hope. Anyway, I'll report back if I get around to it.
Otherwise, use an actual 1amp AC adapter whenever possible. Shop on eBay, chargers are stupid cheap. Just look for one that says it can do 1amp/1000mAh. If you're using the phone at work and want to have a convenient charging source, get one of the $20 docking cradles with an AC adapter on eBay. If it's in your car, any 12v USB charger should work, as long as you use a proper pass-through charging micro USB cable and not a "data cable". There's a slight difference in how the pins are wired inside. The Rocket Fish brand of micro USB cables are known to work (that's how I charge mine at full power in my car).

I'm using the included charging cable. Doesn't that have full capacity? I also use a standard USB adapter in the car. It seems like that would be able to output the correct amount of volts.

I had the same problem until I noticed how hot my phone was using the nav. 13 hour drive. I purchased a vent cradle for the car and so that it can stay cool while in use and charging. While the other guy may be right theoretically, its not right practically. The evo will shut off its mini usb hub once it starts getting dangerously hot so that it won't damage your phone. Long story short make sure your phone is at safe temps no need to buy another charger for your evo. keep at cool temps so that phone won't cut off power supply will even shut your phone down if its way to hot, happened to me in atlanta not fun.

When you say "included charging cable" do you mean the wall plug that came with the Evo or just the cable with a USB connector on one end and a micro USB on the other end? Because THAT cable is pinned as a data transfer cable and designed to relay only half voltage no matter what you plug it into. I know, because it only charged my Evo at slow speed when plugged into my USB car charger. Once I replaced it with the Rocket Fish cable it charged at full speed.

See above. While I agree that heat will kill the battery and possibly trigger a shutoff, I don't think that's his problem. If you use the wrong cable or charger you will only get half charging current.

I mean the USB cable that comes in the box with the EVO that plugs into the AC adapter. Maybe I will look into a new cable then. Hmm.
Edit: Those Rocketfish cables that you mentioned seem to be ungodly expensive. No way in hell am I going to pay more than $5 for a USB cable. Any alternatives?

This is the one I got: http://cgi.ebay.com/ROCKETFISH-MOBI...ARGING-CABLE-/350384355972?pt=PDA_Accessories
$3 shipped
And there are 2 USB cables that came with the Evo (mine anyway), a thick one that was bundled with the wall charger and a thin one that's intended just for data sync. The thin one doesn't seem to charge at full speed.
If you're using the other one and it's STILL draining then maybe there is an issue with heat or something, like the other guy said. Is the phone SUPER hot at the base, where the kickstand is, when this happens?
OP - I am having the same problem. I'm 95% sure it's caused by something wrong in CM6 regarding how it handles USB charging. Past few nightlies I have been leaving my phone on the charger doing NOTHING overnight and it goes dead.
This CANNOT be due to lack of charging strength:
#1 the same exact charger worked perfectly in the past, before I flashed a certain nightly - not sure which one exactly it started in
#2 if it was charging, but slowly why in the world would the battery drain when I have it underclocked to 245 mhz and the phone is sleeping with screen off?
On my standard charger that came with the phone it is working fine even though it's a USB that plugs into an adapter - not sure why this doesn't work with my other one that I had from another phone since it worked perfectly before. Something is definitely odd with CM6 and USB charging.

That's odd, because my EVO only came with the one cable for the adapter. Phone stays cool.

I've also noticed lately that my phone will charge insanely fast. Like from 30% to 90% in half an hour.
Sprocket - stupid question here... do these Rocket Fish charging cables also handle data transfer just as well as the stock micro-usb cable that came with the phone or would someone want to have one JUST for charging and keep their stock cable for data transfer purposes?

Sorry I was unclear - the other cable I have that is the problem is one from another phone but the same type, and up until recently it worked perfectly.
Getting ready for a cross-US trip next month and just noticed something with my GNex vs my 4S.
On my 4S attached to my 1A cig lighter charger from Belkin, I am able to charge the batter while navigating with GPS and screen on. This is using actual navigation, not the built in stuff for iOS5 and earlier.
I simply assumed the same would be true of my GNex but I noticed today that if I am using Google Nav with the screen on and connected to the same 1A Belkin charger, I lose about 1% every 20 minutes or so from my brief testing.
It doesn't appear to be overheating as the charging lights and symbols on the phone continue to show charging and the phone isn't all that hot. It's also not been using for any really long trips yet so it hasn't had a lot of time to get super hot if it's going to.
Just curious if this is common for the GNex while running only GPS with screen on.
I did some searching but the other complaints I found involved people also streaming music while using GPS nav.
People have reported this, and it makes sense if you're on a 1A charger, especially if you have a Verizon model connected to LTE. This is similar to the complaints that people can't charge on a 500mA USB 2.0 port while tethering LTE.
I personally don't notice it draining when I'm listening to music (stored, not streaming) and Navigating, although it's usually on trips of 45min at most and I have a GSM model. My battery seems to just hold or barely charge. I'm not sure of the exact output of my charger though. It's an AT&T branded accessory with a main cable, and a second full-sized USB port.

Yup, normal for the LTE models. It was actually one of the biggest complaints when it was initially released. Turn off LTE while using navigation.

the next nexus needs an IR blaster. think of all the diabolical fun!
I haven't tried it on my Galaxy Nexus but his was certainly the same on my older Nexus S.
Verizon Nexus here and I have no problems in this regard.
I usually stream Pandora while using Google Maps Navigation and have a little speaker plugged into the USB port on the charger and it still charges the phone's battery.
LTE is on as well. Never turn it off.
Using the "MicroUSB Dual Vehicle Power Charger w/USB port" charger from Verizon.
Use Battery Monitor Widget and see if it says "AC" or "USB" when it's charging. You want to see AC or it won't be pulling enough juice. If you see USB, try a different cable. You can also force fast charging with the proper kernel. I use Franco, which has an option for it. That alone didn't seem to help, but I bought the Fast Charge app, which seemed to do the trick.
I just went through this myself on a 2 week motorcycle trip. I used a 3rd party GPS app the entire time, screen on, and streaming music. I had LTE on and I believe as long as my screen was set at around 65% or less I never had an issue.
So, yes it can be done. You just need to figure out the right setup. I did some research before my trip and from what I read, not all USB cables are the same. On my bike I had a low-profile dual USB charger.
90% is the USB cable.
It happens on my Galaxy Tab 10.1 with the default Samsung USB charger, when I connect it to my laptop. Then, if I browse on Internet with the tablet, my battery drains faster than charge, even if connected to the laptop with the USB.
The key is to discover if there is the USB or calbe problem with A output.

Sure enough, it was going to USB on the car charger. I unplugged the phone and went in the Franco Kernal Config and enabled USB Fast Charge. Plugged it back in and it recognized as AC and true enough, it charged my phone while using Nav so YAY!
Only problem I'm having is that on any reboot, even though it is still checked in the Franco Config, I have to uncheck USB Fast Charge and recheck it before plugging it into the charger for it to not go back to USB.

Not sure why it's needed, but after I bought this:
https://play.google.com/store/apps/details?id=com.incredicontrol.fastchargewidget
I only needed to toggle the widget to fast once, and then my problems went away. Worth a few pennies prior to the trip...
I boggles the mind why this is set up this way in stock form..
why??
BTW to the OP, I just switched from a 4S, also had a 1amp charger that did the same as yours, that same charger on the Nexus won't charge the battery with GSM model. It drains about 3-5 % over around an hour commute, more if the sun is directly on it and it gets hot.
Still, why does it seem to force a .5 amp charge when the capability is there for more??
This is annoying that you have to grab up a custom kernel to do this. With JB I'm quite happy with the way the phone is stock and non-rooted but I guess I'm going to have to root and throw on a custom kernel after all.
If you like to solder cables, you can mod your car charger to register as a AC charger.
Give me a second, I'll find the thread.

I love my galaxy nexus(verizon version) however there is something about it that drives me insane, and it is a fact that has been noted on almost all android phones, when plugged in the battery can die, this commonly happens to me when i am trying to use navigation, i will be on my way to someplace where i have no idea where i am, or where i am going and just when i need it most, the phone, that is plugged in WILL ****ING DIE, and i will have to stop on the side of the road and charge it for twenty minutes or drive twenty minutes in the wrong ****ing direction, conveniently, since it is my phone that was doing the navigation, i also cant call anyone for directions, this, to me personally, seems ****ING INSANE, now it is my understanding that the charging rate for the phone when plugged into what the phone percieves to be an ac adapter is capped at 800ma, and 500ma when it is plugged into a usb source, regardless of the output of the charger, it will charge at a rate of no higher than this, presumably these caps were put in place to keep the battery from blowing up, or the phone from overheating, my question is, can these caps be changed or are they hardware caps? i dont care if my phone blows up im willing to assume the risk because it is likely that if it does this **** again ill get out of the car on the ****ing highway and spike it into the ground like i just scored a ****ing touchdown, i know that the usb rate can be changed to the ac rate through the usb fast charge mod, however this simply(in my understanding) tricks the phone into thinking that it is always plugged into an ac adapter, and therefore it is stlll limited to the 800 cap, this also means that the phone can not be used through any usb interfaces while this is occuring, which in my situation is a problem because i use a usb stereo in my car that reads the songs off my phone(grom android adapter very good btw), so my longwinded question is can the caps for the usb charging rate be raised to say 1200ma without loosing usb acess? and if that not possible, can the ac cap at least be raised to say 1200(speculative number just needs to be more than the max draw of the phone)? anyway thanks for reading my rant and putting up with my ****ty internet grammar

You're stuck with 500mA if its coming from the USB port in your car (which charges like a PC usually). And if you go to "fast charge", you'll lose USB file access, yes.
Your only choice is to choose to go with a "fast charge" kernel and lose USB file access, or get a 2A car charger that'll keep it topped up. Less satisfactory but an option is to turn off LTE, which is a huge battery drain.

that what i mean i have a 2a car charger, it still dies, theres a cap on that charging rate as i understand it, 800mah, can that be adjusted?
i believe on a non samsung charger you are capped at 500ma
but if you use a fast charge kernel i don't think it is limited to 800ma
well
I had the simiar situation. well, LTE drains the battery like a hell, and USB charges freaking amazingly slow...
I solved that by using custom kernel that supports fast charge, and did it..
but if u use the fast charge, you will lose the USB link option, oh well,
U can turn the fast charge off to use the USB.
sucks that you can't have both rabbits.

My battery life sucks any Ideas
Ya my battery dies when I use the car charger. Ur best solution is buy another for just the car.
--------------------------------------------------
If I have helped you.... hit that sexy thanks button. ^_^
nobody directly answered the question, is the non-usb charging cap hardware based or software based? can somebody who understands the kernels answer it?
Easy trick is to turn off the screen if your battery is low, you'll still get audible navigation.
Doesn't matter if the charging cap is software or hardware based, no one has gone above it anyway.
Cool story bro.

Where are you guys seeing 800 mA charge rate?
I was going to ask the same question but will post here instead.
Can someone confirm the 800 ma charging cap ? Where is this info found ?
I had a different android phone ( cannt remember which ) and had found in its forums some kernel code someone posted with a 700ma cap for that phone. I will try to search for that reference.
So basically anything over 800ma is overkill and we will not benefit from it ? Is that correct ... includes wall chargers and car chargers....

The charging amp branded on the chargers only tells you how much the internals of the charger can endure.
It is the phone itself that controls how big amp it will receive (usually 500mA or 1000mA). So you could have a 50 A charger and still only pull out 1000mA.
The limitation to 1A is of the spec that USB standard have.

These guys have it. I used to suffer a slight drain even when plugged in via USB if I was gaming, but then I cahnged to Trinity kernel and now I just turn on USB fast charge if I'm charging from the computer while gaming heavily. Don't need USB file transfers while I'm playing.... and I presume you don't need it while you're driving either. Just flash a custom kernel, problem solved.

I have a question about my used phone LG Optimus G E973. It charge very slowly. It always take about 6 hours for a full charge. If I use the phone, the charging percentage won't go up but go down slowly even if It is being charged.
Is it normal for this model?

change the charger,.... mine too takes 6hrs on lg charger.. am using .5amp rated charger of lumia 520 .. it charges it in 2:30
I don't think because of charger. I use the same charger with my iPhone and it charge very quick.

I did, still slow. I guess it my phone. I just want to make sure that all phones of this model are the same or just me.

Since the iphone has a different battery, the charger is also different.
To make sure your battery doesn't die, I suggest you use an LG charger, or at least a charger for a phone with the same amount of mAh on the battery (2100, in this case)

I've been using LG Charger to charge my LG phone. It's already the same model. And you? Do you have the same model as mine?

I own the E975, which is slightly different, but the specs are the same and I have not run into this problem before. So I'm guessing it's an error in either the USB-cable or the phone's battery. I'm not sure though.

Too bad. So there is something wrong with my phone. Is your main power 110V or 220V? The power in my place is 110V. Sometime I get message "Slow Charging" when I connect my phone to the charger.

I did a little research (I googled it) and that might just the cause of your problem. Many people have said that charging on a 110v outlet is not only slower but also less efficient. To charge your phone faster with a lower voltage oulet, they recommend to buy a charger that is specially made for that voltage, but that might not be a problem since also my charger (LG charger) supports voltages from 100V up to 240V.
"In a very layman terms, voltage is what drives the real power (amperes) into your device. So the lower your voltage as per specified rating then the lower the movement of power to your device.
However, when power moves slowly into your device, it stays longer"
I hope this gives you enough information concerning your problem
Sound like I'm lucky to have a phone which can be charged slowly. How many percents you get if you charge your phone for 15 minutes?

I am sorry in advance, my comment is not directed at you personally, since you found this info online...
This is a complete and utter nonsense. It's not even funny, it's just dumb. First off, auto-sensing chargers will work with any AC mains within standard tolerances. 110V, 120V, 220V, 240V -- doesn't matter at all, the charger will output stabilized 5VDC, and will supply the current (Amps) up to its rated maximum. Also, saying that the voltage drives the amps is another BS. The voltage in this case doesn't change -- it stays at 5V (unless you have a crappy or defective charger, of course). Only the charging circuit in the phone determines the current that it draws from the charger.
Speaking of the OP's problem, there might be different reasons for a slow charge. All of them have already been mentioned in this thread. The easiest thing to check is to change the USB cable. Speaking from experience, I have two particular cables that consistently exhibit this issue -- it all depends on the conductors (wires) and the quality of connections. Grab another cable, and see what happens. Next step would be to change the charger for something rated higher (2A, for example). I am 99% sure either of these replacements will fix the issue. If neither of these things work, then there may be a problem with the battery, which can be replaced. The worst-case scenario is a problem with the phone itself (highly unlikely)...

Well, explanations like those you quoted could be reasonable to some extent only if you have a really bad charger (either broken/defective, or just made like crap to begin with). I am talking about properly designed and functioning chargers. I have a wonderful example of a cutting-edge engineering from China sitting in my desk drawer: it's a microUSB car charger, which has direct connections from a 12VDC socket to microUSB pins, protected by a 5Amp fuse. Oh, and a cute red LED light, of course. :silly: When something like this is used, anything can happen... If a phone survives, it could be a good advertising for a phone's manufacturer: "Our phones work no matter how hard you try to kill them!"
As I already mentioned, I think it's neither charger nor cable problem. How do I guess that? Well,
1st, I charge my iPhone with iPhone cable and "A" charger. It charge very quick so "A" charger shouldn't be a problem
2st, I charge my iPhone with iPhone cable and LG Charger. It charge very quick so LG Charger shouldn't have problem.
3rd, I charge another android phone with "A" cable and "A" charger. It charge very quick so "A" cable has no problem.
4th, I charge my LG Optimus G E973 with "A" cable with LG charger. The charge is very slow.
Therefore, I guess, none of the accessories have any problem so I think I'm the only one in the world who have this problem.

your phone usb port might be a defective one lol
My LG E975 used to charge frustratingly slow when I first bought (20 percent over 3 hours). Before taking it to warranty, I did test around to see what's the problem and found it was because of the cable. Some cables work better than the others though. I used the LG charger with the cable of my Sony phone -> still slow; with Asus tablet cable -> working normal (1 percent up every 1 - 1,5min).
Further testing, I used the "faulty" LG cable to charge my Asus tablet, and it worked fine. So (I guess) the USB port of the phone is just being picky on cables . Try charging with some other cables for a few minutes to see if any works for your phone.
any way to change the currents charging voltage in kernel? i have this issue with CM11 but not on stock
So I'm having a problem (I think). Until now, I charged my S20ultra with its very fast charger and with my wireless anker (10W model) connected on my usb pc port. While connected on USB port, I know the charge is very slow (takes like 5+ hours from 0 to 100%) since it uses only 5W but I dont mind since it's wireless.
Today I conncted my anker wirless to a normal charger (its the one coming with samsung A51, supports fast charge). I thought that would speed the wireless charge up (since my anker is 10W but on pc usb port it can only use up to 5W), instead its still slow. Using accubattery sometimes i see the actual charge rate rarely go up to 800mA but almost all the time its about 200-400mA. My phone right now is at 54% battery so its not even at the end of a charge (at the end i know it slows the charge up with all chargers), accubattery shows 13%/hour charge which is very slow. Anyone know why this is happening? Why isnt my wireless anker using its full speed?
PS Android says its using wireless rapid charge, so its not like it doesnt recognize it. I also tried removing the cover but doesnt change at all.
Not sure what output your A51 adapter does, but for full 10W output on the Anker wireless charger it must be plugged into an adapter that does 9V-2A output and QC3 compatible.
You can find the output on the wall charger by reading the very small print on it

Thank you!! Well this might actually be it, the A51 adapter is 5V-2A or 9V-1.67A. I guess this might be the reason then... since you've been so kind and you have exactly the same wireless pad I use, can you please link me your adapter? I was thinking to buy this anker one: https://d2211byn0pk9fi.cloudfront.net/spree/products/57202/product/A2010311_ND06.jpg?1505382537 Has 9V-2A and its QC3 but just to be sure i'd rather go with the one you got since its working. Thanks a lot!
I use a Motorola 27W PD adapter that I had lying around from a previous device but that Anker one you linked should work no problem.

Thank you! One last question... do you think the lack of usb-c port might be a problem? I noticed your adapter uses it but my anker pad has a microusb-usb b cable so I cant use an adapter with usb c but just the old normal usb port... was wondering if that might cause problems. I guess you use a usb c-microusb cable to connect your anker to motorola charger right? Thanks!
Not being usb C on the pad shouldn't be an issue, comes down to how much juice the wall adapter pushes out . And yes I use a USB OTG adapter (usb C male to USB A female) to work with that moto charger. I think you should be fine with that Anker charger you linked and then using the cable that came with the pad.
I only use wireless charging over night so I haven't really tested to see charge rate as I just let it go as I sleep, I'll make an effort to watch it sometime to see what actual rates I'm getting.
Hope that helps .

Just an update... i received the charger today, but even with this one so far it doesnt seem to change much, it charges like 12-14% per hour. If possible I'd really love to hear from you if your experience is different, I know its hard since you just leave it to charge during night, but maybe if sometimes you happen to charge it for an hour or so during day would be interesting to see if you have similiar results or a faster charge... thanks again!
This is what I'm seeing, granted I was already charged to 60% before I took this screenshot. Also I have an S20, so smaller batt than its big brothers ..
No charger (wireless or wired) will ever reach their theoretical charge rates ... I know me using an OTG adapter into my PD charger leaks power almost as much as wireless charging itself . Convenience is why I use it though..
I think for the best/fastest Qi charging, we have to get the Samsung official charging docks/pads.

Thank you man... one question, does it stay at around 1100-1200mA all the time? What I noticed is that my phone sometimes goes up to even 1400-1500mA but it stays like that for a very short time, few minutes, then rolls back to 200-400 most of the time (so very slow). If your phone is always charging at least 1000-1100mA then for sure theres something wrong with me, but i read a lot of other people seem to have problems with s20/s20+/s20ultra wireless charging, even with the samsung original 15W charger. Thanks!

i never see drop below 1000ma, is the low end... again as i charge overnight I'm not sure if it drops past that, but it sounds like you have way slower charging than me..
i still carry my anker pd charger for true fast charging
edit.. is your device snapdragon or exynos? I'm snapdragon

Mine is Exynos, and even the 20+ from this other guy having problems with samsung own 15w wireless is exynos. Would be sad if this was just another problem with exynos, not being able to charge it as fast as with SD. You've been very kind, the last thing you could do is maybe sometimes when you charge it, see if accubattery is really always at 1000mA or more, or actually drops by half if not more for you as well sometimes. I'd be happy to even have a steady 700-800mA charge, problem is that its almost always under 500, but for a very short time i DO see it going up to 1400 so it means the power provided can reach the phone, it just doesnt last, i really wonder why.
If you could check once in a while would be really appreciated. Thanks man!

It's been solid @ this rate till ~60% then drops down to 1000-1200 ... haven't seen any spikes or dips, it's pretty consistent. Don't know what to say, it's a bummer that your device seems to have issues with Qi charging. And doubly sucks if it's an issue w/ Exynos devices. Wish there was another person here who could chime in

Seems everything is in order with you. I also wish more people would jump in sharing experiences, sadly it seems not many of us charge it with wireless. Other day I was searching online and on Reddit I found some s20+ exynos user with the samsung 15w wireless original charger with the same problem, there would be almost no difference between that charger and a 5w one. The chances that its both his charger faulty and my s20 ultra as well are very low (beside my s20 with cable and 25w samsung charger goes to full in about an hour, and if it was a problem with wireless it wouldnt charge at all all the time ), so maybe the problem could actually be exynos but who knows... anyway thanks a lot for your help, lets hope someone else jumps in this thread. I was almost rdy to buy the (very expensive) 15w samsung charger but at this point im not even sure its really faster.
Update: just put on the pad to charge, was at 26%, went to 32% and accubattery showed always 1400-1500mA. Now its stuck below 500 again, temperature 36.4C so not even hot to drop. I really am gettin pissed off at this, how is it possible it charges full power for a short time and then drops.
Another update... Anker just replied to my email sent days ago about my problems with the charger, here it is:
"Recently, our various markets have feedback that this S20 cannot achieve fast charging. The specific reason is that our engineers are still testing. Because we did related tests before it was put on the shelves, there was no problem. But now it is confirmed that there is a problem, so we recommend that you do not buy new products for now."
So apparently there is a known problem, altho im not sure hes talking about s20 in general or about s20 ultra since i wrote i had an s20 ultra in my original email. Also its not clear if its just markets with exynos or those with SD as well. But it does seem that there is a problem that they know about...
