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.
The original Samsung charger outputs 5V---1000ma, I have an extra blackberry micro usb charger that outputs 5V---750ma.
I want to use my old blackberry charger in my office, will this different current output affect my battery long term or short term?

One of the immediate side effects will be that your phone will take a longer time to fully charge your battery.
If I helped you out in any way please thank me. Thanks.
Not sure how the blackberry chargers are. I know some of the Motorola chargers are accepted by the phone for high current charging (any charger that doesn't puts the phone in low current mode).
I charge my phone every night on my old 700mah Samsung charger and while it does take longer youd hardly notice unless you were trying to get as much charge in say an hour as possible. So as long as the phone doesn't limit it you should be good. <500mah is very noticeable.
I know it will take longer to charge. But Im not as familiar with appropriate charging output for li-ion as i am for ni-mh Sanyo eneloops for example that ideally should be charged at 220ma to maximize cell life.

The rule still applies the less current used to charge the better the lifespan. The phone was paired with a battery with the intention of using a 1 amp charger. The phone will only allow high current charging mode if it thinks the charger is Samsung. Shorting the data pins is a way to fool it and many aftermarket chargers already do this.
With your phone on and the phone in low current mode (320 mah i believe) you will have a hard time charging the phone if anything is wake locking the phone even screen off. You will even have trouble charging and using the phone at 500mah depending on whats going on.
The phone will be eating some amount of power from the charger, the battery is not always seeing as much current as you might think. I always stick by the practice of not deep discharging it, LiION would rather be topped off then not charged (geeze remember NiCad laptop batteries.... lol). I feel this battery will be the shortest lifespan of any phone or laptop I have ever had. Just due to how much use it sees.
Charger
Any micro usb charger should work. I've had a dozen or so different gadgets that all use micro usb from Blue Tooth headsets, to speakers. I use all chargers interchangeably with one noteable exception. My wife's Nook Tablet will only charge using the provided Nook charger. Found that out the hard way.
I have also found that not all micro usb cables will provide data transfer for all phones. I'm guessing different pin-outs? For instance when I was trying to root my ET4G, I forgot my OEM cable at home so I tried to use my EVO cable. That dind't work well at all.
My old blackberry chargers seemed to work fine but I started seeing some strange jumping around of the battery while using. For instance it would all of a sudden jump up to 100% charged then if I unplugged and plugged back in it would go back to 70% or whatever. I went back to only samsung or just charging off usb. I use my pc, printer, cable box etc to charge my phone.
I charge mine with either the stock charger that came with my E4GT, or an old 700MAh charger that came with my old Samsung Rant. Occasionally I use the charger that came with my HTC Evo 4G. I really can never tell a difference. Although, like someone above said, it seems as if non-Samsung usb cables will not charge when plugged into a computer. That's how it is with the HTC cable, and I've also tried an LG usb cable and got the same results.

I had the exclaim, the replacement to the rant and thats where my 700mah charger came from.
All of my other Micro USB cables except the one are non samsung and I use them all for charging, data and they charge while connected to pc. But none of them are from other phone manufacturers or anything. The Micro USB spec is what these phones are using there is no difference.
The difference that matters most of the time is tolerances. Its easy to end up with cables that will work well in one port but not another. The rest of the cable may also be out of spec and not work well or at all for certain purposes.
I've ruined two batteries because of non-OEM chargers on the ET4G. (Actually, ruined two, and made a third battery just render terrible performance.) I definitely don't have the problem with other devices I own, and it's definitely happened with two separate ET4G's I've owned.
So, "be very careful using alternate chargers" is all I would advise.

Please correct me if I'm wrong but isn't electricity the same no matter the source?
If the phone is looking to pull 1A and your charger is rated for .7A I'd be worried about the charger not the battery, which technically is a cell not a battery.
Tolerances were mentioned before and I think that is most of the problem with certain cables working fine for some people and not others. All connectors and cabling are supposed to meet the USB spec and many cheap ones don't. Also the supposed 10,000 insertion rating for micro USB is a bit optimistic imo. I replace cables after a couple months max because of loose connections.

Not really because these chargers are doing AC to DC conversion and voltage regulation is a huge factor in its job. With a bad charger design not only can charging be affected, possibly even hurt the battery. Since the phone will consumer charger power to run while on the charger the phone can become unstable. Not talking a defective charger, just bad and cheap designs.

I think about that alot actually. Coming from PC power supplies you never want to overload the unit. But I know for a fact I have devices that demand more from chargers than can be given, and do not have the low current and high current modes like this phone.
I am no electrical engineer and am only familiar with AC to DC and DC to AC circuits and various voltage regulation techiniques. But it is possible to current limit as well right? You design a half amp charger, with the data pin short to put the Samsung into high current. You limit the current to 500 mah but over build the components just a little to increase lifespan.
Anyways, I bought a 2.1 Amp RCA wall charger from walmart last night on a wim. 9 bucks, might come in handy when i get a tablet. Has a 1 Amp side and a 2.1 Amp thats shared with the 1 Amp. Phone didn't show any ill will to it and I had my Schosche GoBatt on the 1 amp end. If the phones drawing too much current could be bad in the long run but its working so far. Charged at the normal speed of the stock charger.

I agree with you on bad and cheap designs. How many tv's and other electronics have been rendered useless by a few substandard capacitors that saved the manufacturer $.02 per unit?
I try not to use any charger that doesn't have HTC, Samsung, etc on the label. I figure if they were willing to back it warranty wise for the original device it should put out clean enough power.
I'm far from being engineer but I do quite a bit of hardware hacking and learned a little bit about electronics when I was at Ft Gordon. So I'm not completely lost around a multimeter
I would imagine that there is some protection built into the charging circuit of the phone itself. How effective or what kind of tolerance Idk suppose I could look for datasheets if anybody really cares.

Hi everyone,
I have a problem with my original wall charger that came with the phone. There seems to be something wrong between the cable and the connector you are plugging into the phone. I need to have the cable in a specific position for the phone to be able to recharge.
The question is, is there any better charger than the original samsung one? I could probably get it replaced as it still is in warranty, but I don't like how slow it recharges the phone. If I am running a 3D game the phone is slowly DISCHARGING even when plugged in to a wall charger.
I noticed the charger has only 500-700 mA output. I had an older htc charger which had 1000 mA output. Would a charger like this recharge my phone faster? I have seen some posts about non-samsung chargers not being able to recharge the battery fast as there is some kind of protection built into the phone.
I would also consider buying a wireless charger if it was available for a reasonable price.
Are you all using the stock chargers?
Thanks in advance for any help.
you can read this thread: http://forum.xda-developers.com/showthread.php?t=1721677&highlight=charging
Just to make sure it is the charger's fault, does the phone charge normally if connected to a computer, from the USB port?
Thanks for the link.
Yes, phone charges and transfers data from USB without any problem, so it should be fault on the charger.
Reading through that thread, I guess there is no point in buying a more powerful charger.
as i said there, i use a nokia 1200mAh charger and the charging time is more than 2 hours, so we have to deal with it. The thing you should care of is the quality of the charger to avoid the touchscreen known problems
Imho you don`t need better (more powerfull) charger because of the hardware limitations. What you should do is to try any other microUSB charger just to see if that solves your problem. So if any of your friends of family have other samsung or nokia etc. phone, thats charging with microUSB, plug it into your phone to see if it solves your problem. You will know what to do next if it does

I have a 2meter USB to MicroUSB cable(EBAY) plugged into mains which does Not charge the phone when screen is on. In fact it Loses charge when watching films .
But when l plug in the one that came with the phone (1 meter) it charges the phone no problem, regardless of what you are doing.
Anybody have any ideas for why this is happening?
Length of wire? or just bad quality of wire? But l have tried a few different 2m ones. Same drain.
(Also same results with different roms)

You might have noticed that smaller the phone, the larger the charging cable comes with it.
and the larger phone, and tablets have decreasing charger cable lengths. Also, the charging cable become thicker as the device becomes more power hungry.
This all comes down to a simple explaination that longer and thinner cables have more impedance, and thicker and shorted cables have less resistance...
This is to cover up for the amount of power the device will consume in order to get charged, and hence, result in a different "quality" of charge.
Also, some cable, like that of Nokia, do not run on touchscreen samsung phones. This may also be because of the difference in power output, as they may not fulfill the requirements which the latter needs.
Ok, so how about getting a beefier longer wire? I've seen a brand one for 10 £ claiming to be grippier blah blah. Obviously no claim for what it's able to charge and how fast.
Will this change anything?
I'm guessing im doomed to be always leaning in to the wall if wanting to use the phone and getting it charged.
And thanks for explaining things, sadly that is what I feared.

It is not definitely that beefier and shorter wires will charge quickly/better. They need to have correct power ratings and other j7mbo mumbo, which is most definitely best in the stock charger you get
Just buy a usb extension cable with plug and socket on each end. You have to use the Samsung charger AND the Samsung USB> MiroUSB cable. Beetween you place the extension cable.
The reason is, in the Micro-USB-Plug of the Samsung-Cable, i think there is a Resistor between pin 4 and 5 that makes the Phone change into high-charging Mode (AC-charging).
Otherwise on USB-Charging you have only 500 mA. That is not enough for the Note 2, if the Screen is on. The Phone will not charge.

Thanks. .. should of tried that. Forgot I've loads of them.

Same here, with random internet cables it just doesn't charge fast, but yes with the original.
I was looking for some good cables to use it but I didn't see any info to know what are the faster ones for charging.
Right, some bad news regarding USB extenders, I used a 2 meter extender with the white stock Samsung cable.. screen on, torrent app downloading, did NOT charge at all. But did not lose anything either.
I then found a 0.3 meter USB extender with stock Samsung. And it is charging, but I would say it isn't as fast(very close to normal), but the main thing it is slowly charging. Make what you will of this.
My USB extenders are from ebay crap
I have a s2 original charger
Output 0.79 takes 7 hrs to charge note2
Original note 2 charger is fast charger
Output 2.00 tkes 4 hrs to charge the phone
So it depends upon the uotput of the charger as i use the s2 usb to charge wt note 2 charger and again used the note 2 usb to charge 5he phonr at both time the chargin time was same
So i think the length or thilness of the cable dosent matter only thing matters is the charger output
Secondly if u use nonoem cables or chargers the usb port may give off or ur phone freezes while chargin so pls avoid nonoem cables
U can use oem cables of sony , htc, blackberry, even micromax and spice in india which r runnin androud but dont use first copy of chargers ir cables as they would harm ur phone
Hi Guys,
I have a thinkpad which has regular USB and also a fast charge USB port. They have worked fine in the past on other phones and I used to see at least 1 amp charge rates. (on the fast charge port)
Using either port on the 20 X I only get about 200 ma charging rates?
I'm using "Ampere" to get the charging rates, it is definitely charging slower than normal...
Have you guys noticed this?
Also of note, It charges really slow from my car as well. On the hour drive home the phone only went up 4%. (This is a VW using android auto)
I think all bets are off when your using 3rd party chargers. I think Huawei might have some official accessories that you may need to buy.

I have a bunch of phones and every single one of them charges at normal charging rates off my laptop and in my car, this is pretty strange...
Huawei uses a completely different setup from QC 3 from charger to cable . How does it charge with the supplied charger and cable that you received with your phone? If you buy extra chargers for home or car make sure they say they do Huawei "Supercharge". They are a little hard to find but they are out there. Make sure the USB cable is rated for 5a(amps)

I haven't even used the included charger and cable, but plugged in at the house I do see 2 amp charge rates which is great.
The downside is that in the car with android auto I can't really plug it into anything other than the car's USB and that give me a really slow trickle charge. This is where a bulk of my charging occurs since I drive for work so much. Basically I have never charged my other phones outside of the car, I just use android auto all the time and the batteries are always topped off. So not being able to charge from car or laptop is not a deal breaker at all, but it certainly means I need to start carry a charging cube around everywhere.
Just seems odd for such an expensive flagship phone to not charge correctly via USB like every other phone I have ever had.
Try the supplied charger and cable just to make sure you do not have a defective phone. When you plug in the cable to charge watch your screen. It should show your battery percentage and a short lighting bolt. Then in just a second it should change to a long lighting bolt and say super charging. If it does that you know your phone is charging correctly. Take your Huawei supplied cable and use it on your laptop and car and see if that doesn't increase your chances speeds.

I gave the original cable a shot and it still basically charges at 200-250ma from my laptop. Very odd indeed. Not even seeing the normal 500ma that you would get on a regular USB port. (Tried both standard and high charge rate USB ports on my lenovo)
Anyone else seeing this behavior?
