Running latest Azrael rom (3.0) with latest OTA Radios, Kernal etc and have encountered odd issues when tethered via usb. I have seen this happen before on the Sprint lover's rom but generally have not used tethering much so did not worry too much about it. When tethered I have found that connection speeds tend to be very good and then all of a sudden the device goes from 90% or so charge down to fully dead in no time and find the phone has a bllinking orange light on.
I have tried different cables and also running battery monitor and found that it seems like a charge was maintained up until a certain point and then it drops off all of a sudden almost instantly. I have tried this with 3 different batteries and still the same thing happens. I am using a desktop pc and I have tried measuring voltage output on the gigabyte motherboard I am using that with recent bios updates has high voltage scaling output beyond the normal 500mA usually associated with USB.
Anyone have any suggestions or does this seem like a hardware issue?
Thanks!
One last try any suggestions?
Well there is an issue with trickle charging on the Evo. Once it hits 100% the phone switches completely over to battery use REGARDLESS of whether or not it is plugged in. So the phone will think its at 100% battery but in reality the battery is draining. There is a kernel that addresses this issue but it is in beta.
Also I noticed that my phone charges a LOT faster when its plugged into an outlet instead of via USB to my PC. Maybe the power from the USB port is not sufficient to supply a USB tether. Once again I'm not 100% on this.
Maybe the USB tether stops the phone from charging.
I have yet to tether long enough to have my phone die when plugged in. Then again I use WIFI tethering instead of USB. Maybe I'll try to reproduce the issue.

Thanks very much I appreciate any help you can provide. This helps explain things a bit. I have done some voltmeter testing on my usb ports and have found that with a recent firmware update these ports scale up the voltage output based on the demands of the device connected. I have been able to verify output for other devices exceeding 500 often.
Yet for some reason the EVO does not draw anywhere near what other devices do when connected to a USB port, in fact it does not draw 500 most 99% of the time. The power draw I have seen peaks at around 350 with 1 spike over a 24 hour period of 595 with most intervals being 150 or lower.
I wonder if there is some way to trick to device into thinking the USB connection is actually an AC one to allow a the draw of the higher voltage that these newer motherboards are capable of.
Either way I just want to make sure it is not a hardware issue with the device itself. Since it does not take long when the device is tethered to drink the battery in less then an hour from a full charge.
I have seen the Savage kernal and was thinking about checking it out when it was a little further along.
Thanks again.
NP.
Check out this and try to contact the dev.

Sorry if this has been asked before or in the wrong place...
Anyways, when I was using CM7 RC4 I noticed that if I charged my phone by USB on my MacBook the battery life was significantly reduced compared to wall charge. Anyone elts notice this? Or is this just me?
I flashed CM7 Final earlier today, and while at work I read about the GPS fix so I am in the middle of flashing Fresh to do the fix but I am going right back to CM7 final!!
It shouldn't affect your battery life. USB charging will be slower than a wall charger such as the stock one, which supports 1 amp charging and is recognized as an "AC" charger. But once you reach 100%, your battery life shouldn't be affected by how you got there.
When I first got this phone I noticed it charged pretty slow. 5 hours to get to full from 0% but it then got a lot worse. Over night it would only charge from like 18% to 41 so I got a new charger and wall adapter and that seemed to fix it for a couple days but now it is charging slow again. From 70% to 100 it takes about 6-7 hours. Anyone else experiencing this?
The only time I've heard of that happening is when people fail to 'condition' their lithium battery properly before normal use.
In other words, upon getting your new phone, and/or battery, you're suppose to allow your battery to fully discharge and then fully recharge 3-5 times to condition your battery before plugging it back in half way through discharge.
It's usually what the carrier sales clerks are suppose to tell you when purchasing a new smartphone.
Here's a simple article on the subject:

I never had/has/have doing it. And I dont have battery issues.
I think the battery calibration/cycle..etc is just a myth.
Go to the store and check for warranty.

Could it be a rouge app causing it to take so long to charge? I noticed today Google maps was using a lot more of the battery than usual. Almost as much as the screen. I tried force stopping but it just starts right back up again. Any ideas on how to fix the maps app? I have a feeling that is what is causing it.
I have this problem. It is very annoying and I have no idea what causes it. It doesn't happen all of the time though.

Just sounds like a bad install of something. I would do a factory reset through the stock recovery, and make sure to wipe dalvik cache.
My phone has started charging slowed as well, but mostly when connected to the computer. I made sure my usb ports were set to not allow the computer to shut them off to conserve power and it seems a bit faster. As far as charging and discharging ect ect I don't do that and never had a problem with slow charging and even the couple of times I tried it, the battery life never really improved. So think it is needed and some think it is a waste of time.
Charging via a computer USB port will always be slow when compared to the higher current capacity of the included AC charger. Computer USB ports have a lower current rating.
Make sure your using the charger that came with the phone, not all chargers are created equally.
There's also been some talk about the quality of USB cable being used, but I haven't found that myself yet.
Little bit of info...
I have tried numerous chargers while at work here (Technician) and there are some issues.
Samsung is funny on which chargers it accepts. Very funny.
1. Stardard charger that comes with the device will charge best. (Obvious I know) Using wall charger. (Full charge in 3.5 to 4 hours from 1%)
a. Using USB end plugged into PC while charging takes typically from my tests double the time to charge. (I'm guessing that data connection to PC is slowing the charge. (Full charge in 6 hours from 1%)
2. 3rd Party Generic charge cables (usb cable only) still charges device however stardard power draw is lower and does not charge in a decent time period.
a. Some 3rd Party usb cables plugged into a pc showed charging however they did not keep enough of a draw to actually charge my phone. I lost battery instead of gaining.
3. LG chargers did nothing for me. Couldn't get a decent charge.
Motorola chargers gave me the best charge besides the original.
Chargers with replacement tips... what can I say. They didn't seem like a good idea and weren't. I had too many issues and at times had some overheating issues. Luck of the draw me thinks.
3rd party wall chargers were hit or miss. A few did seem to give me a decent charge, others gave me a very slow trickle charge taking anywhere up to 8-9 hours for a full charge from 1%
All in all... it's a crap shoot using 3rd party cables. It's all based on voltage output and Samsung likes to change things alot. You will still get a charge but who knows the length of time it will take.
Oh and car chargers... typically only good for keeping it at the same level you plugged it in at for short drives. Long drives obviously work much better.
Hope this helps.
About charging: I have noticed that micro USB cable that come with S3 is really bad - it is loosing a connection to PC,and, beside that, I have noticed several times slow phone charge... Accidentally went to settings- battery - when I was on AC charger and saw in settings that phone is actually charging in USB mode!!! Wtf??? Disconnect usb from bottom end (at charger side) and reconnect and then on phone says " charging - AC" ... So,conclusion is that you check your phone charging status when you put on charger,maybe it is charging in USB mode and because of that phone is charging slower than it should on regular AC power.
The only battery issue that i have noticed is when i use my computer to charge it takes forever but when i use the factory wall plug and cable it charges quickly with no issues
Excellent post supercholo. Really helpful. I was starting to think my phone was broken.
Anyone got any experience with using an ipad charger on an sIII. I know an ipad wants a lot of power to charge.
FYI These are the voltages listed on my chargers;
Apple ipad1 charger 5.1v 2.1a
SAMSUNG s3 wall charger 5v 1a
Samsung Galaxy i9000 wall charge 5v .7a

Very slow charging with OEM charger.. i9300
This is a fact. The OEM wall charger surely has some issues. Though 1amp output, as claimed on th specs chart, my i9300 charges super slow. From 80% to 100%, it takes nearly 3 hours.
So, i switched chargers and used my S2 and Note OEM wall chargers. And voila, the phone charges super fast. I even ordered a new OEM charger for s3 with the data cable included and the same issue occured.
This has worsened ever since the JB update. So I am now using the S2 charger and very satisfied.
SWTICH OVER GUYS!! OEM charger is useless,,,
I have had my phone on USB to computer charging for 7 hours, with a one hour break to watch Dexter. I was at 18% and I am now at 69%. I think I will have to use the wall adapter because this is just ridiculous.
Usb to pc will always be slow buddy. It outputs 500ma while d wall charger is 1 amp
I found my Usb cable faulty. Sent for replacement.
Cheers

Without reading all the post. I have had this same problem. Took phone to sprint, they tested the battery and it was bad. Got a new one and good to go..
To power up, you consume Red Bull. But your phone just needs its adaptive fast charger. Rate this thread to express how quickly the Google Pixel can charge. A higher rating indicates that it charges extremely fast.
Then, drop a comment if you have anything to add!
Charging speed is amazing. Honestly the quickest charge out of any piece of technology I have ever used. The battery life you get from the amount of time you take to charge is absolutely phenomenal.
What charger are you using?
I'm not using the OEM Google Pixel charger and just using a Samsung Fast Charger, and when connected the Pixel indicates "slow charge".

It slow like molasses in d winter,compared to any quick charge 2.0 devices
It depends on how much you discharge the battery. If really low, it will charge 0-25 quickly. 25-50 about the same as a Quick Charge port. 50-75, about the same as a standard USB charging port (1.5A). 75-100, it tapers off and by 90% charges no faster than plugging into a USB data port (500 mA).
So, if you charge when you can and don't let it get below 50%, it's no faster than any other phone, and any standard USB-A charger will provide what it can use.
Greetings folks! I have been using a new usb cable to charge my phone, and my battery is also new. I was wondering what's the expected charging speed on this device. I have not been aware how fast the charging was with stock cable and battery as I have acquired this device just a month ago. Currently I get 2100mA as the average charging speed which I feel is low as I have a redmi note 4 and it gets 1700mA average charging speed without any fast charging and having a usb type b port. I have attached a screenshot of my last charging session stat for reference.
I would like to know what's the charging speed for you all to get an idea. Thank you.
