Anyone else having this issue? Went from completely dead 0% to now 17% in 2 hours! Maybe it's a bad battery? Used to charge from 0% to full battery in about an hour or less

Yeah I have noticed that, it's iffy sometimes it charges normally on my pc then there times when it just crawls like today it was at 57 % for like 1 hour I rebooted it thinking something was wrong.
My phone was very hot tho maybe that had somthing to do with it idk

never use your micro usb cable connected to your computer to charge your phone. If your phone is ON and playing music or something else, that will still run down the battery even though it is connected to the computer. Your LG G2x charger that came with your phone is rated at 1 amp. The computer usb port is giving out a fraction of that. Even cheap chargers from China that are 350mA - 500mA will take forever to charge your phone. I use spare Blackberry chargers that are less than $5 and offer 700mA. They are great and cheap.

It's very similar to the TF101; it seems most Tegra devices use a charging cable more like USB 3.0 than 2.0, which pushes a lot more power and charges the device quickly but when plugged into a 2.0 port the charge slows to a crawl. USB 2.0 simply isn't designed to push the amount of power these newer devices require.
When I try this it will not charge my phone. I tried on several computers at home and work Pc's. It actually drains it.
I wonder why that happens???
Not a big deal.
No problem, I always have to take my charger everywhere I Goto be safe.
All computers using USB 2.0 or USB 2.0 add-on cards.

Yes, a fraction of 0.5. USB ports can provide up to 500mA.
I just charged mine at work using a USB cable plugged into my monitor. I noticed that trying to charge it off my laptop doesn't seem to get me anywhere. It might require using a powered hub or something similar to get enough juice.
I usually slowly lose charge when plugged into the usb at work. Granted the screen is almost always on and the phone being used.
I've noticed the charge rate for differs depending on the usb charger rating.
For example, on my laptop usb, it charges very very slowly. but when plugged into my desktop, it charges just very slowly. So they must have different current ratings.
When using my eee transformer usb plug ([email protected]), it charges the phone very fast, like under 2hrs. When using a usb charger meant for a blueant headset ([email protected]), it takes like 4hrs to charge. Think the stock charger is at [email protected]
I use Battery monitor app to monitor my batt usage/drain. Haven't really paid attention to the battery gain, but from looking at past history graph, think when plugged into the laptop, it supplied like 5-15ma of juice. When plugged into destop it looks like at 55-400ma. The transformer usb provides up to 1200ish ma, and the stock gives 800ish ma.
Now does using different rating chargers affect the battery discharge rate and health of the battery?
Just because a USB port on a PC says it'll output 500ma doesn't mean it will, it's all up to the software. If your PC or phone is cranky and doesn't communicate properly, your computer's USB port will default to 100ma, and you can't charge off that
Mine charges fine on USB unless I'm trying to use it, then it is pretty much break even.
Hey all,
how much time it takes you to full charge it?
my battery was ~10% 7 hours ago, i went to sleep, and now its still charging ~95%
im using htc charger, and its connected to wall, and its just taking him to long.
tnx
not sure ...my charger seems to work fine..few hours but on usb need soooo loonnnggggggggg...i know its faster on charger but on usb is just too much..
My significant other has the same problem with her Sony ericsson charger (she has an X10 Arc), my charger on the other hand works perfectly.
If you have the possibility of trying another charger, you can find out where the fault is...

My battery was charged from 23% to 100% in 2.5 hour with original wall charger.
That's way too long. Even from 0% shouldn't take you more than 2.5 hours.
Something is wrong with your wall charger.
fffuuuuuuuuuuu
i will try another one
I charge from ~20% to full in maybe 3 hours on USB.
Try charging from USB to see how long that takes.
I will take a few hours, maybe 4, to do a full charge from USB.
If it seems that it will take a good bit longer than that then it could be you cable.
i have another wall charger, and i will try from usb.
will take few days of testing
If you're using the HTC charger & cable plugged into a wall socket, you should be able to charge fully in about 2-3 hours, because the charger should pass 800-1000mA to the phone for much of the time, instead of the 500mA max from a PC USB socket.
It may be that the charger is (for some reason) not getting above 500mA: maybe it's the cable, or the phone is too hot or too cold.
Or perhaps the phone is running something quite hardware-intensive and soaking up half of the power that the charger is producing.
Have you tried running Battery Monitor Widget? It will give you an indication (a log too) of the input voltage and the power consumption over those seven hours.
For comparison, my Desire S runs at under 10mA when idle, and can charge from 25% in a couple of hours.
Might want to try charging when phone is off then.
ok, tried another charger, this one made 70% in less then 2 hours.
so the first one is ****ed, will recheck him maybe with usb-charging
Oh!!!
I always use the usb port on my laptop... So it is the reason...
Hello, I just got my Nexus S this morning and as I am from Australia the UK wall charger that came with it is incompatible so I am charging via usb.
I did a forum search and read some threads and found out a full charge takes about 3 hours. My problem is the battery is charging only %1 every 5 minutes. At this rate it will take something like 7 hours to fully charge.
My question is: Is usb charge slower than a wall charge and would it be ok to charge my phone with a Sony Ericsson wall charger because I don't have anything else? I thought it would be alright but I am just checking because I only got the phone today and don't want to break it.

You can use any micro usb charger like your old phone or any htc charger etc. No problem. i always charge with any usb charger more than 500 mAH like 1A.
USB only has output capabiliy is 500 mA or so
charger got 800 mA or 1 A , i don't remember exact number ...
Thanks guys, I thought it would be fine but it was good to be sure.
If u want a better wall charger use a HTCs and get a thicker data cable... my phone charges fast .. the Modular AC that comes with samsungs phones suck ass lol .. and the think USB too.. buy a data cable that's thick and Ull be happy =D

I think macbooks have more juice in their USBs so I guess it depends on the computer.
But standard is 500mAh.
Ipad chargers and other tablet chargers are good for fast charging.
Are a couple of sites that sell good chronic ones.

I've noticed that charging with 500mah charger, charges the battery MUCH slower than a 1000mah (1amp) charger, which charges really fast. I'll need to time it, but I'm thinking the 1000mah charger charges the stock battery in less than 2 hours, where as the 500mah charger takes many hours, I usually let it charge overnight.
My question is, is there any performance gain to slow charging vs fast charging? ie: slow charging giving a deeper charge, vs fast charging?
any opinions?
i use a 2amp charger i had already that fully charges the O3D in around half an hour/45 mins. get the same runtime whether i use that or the stock charger.

Any chance of a link to this charger, I'd really like that sort of charging speed.

My guess would be anything that would charge an iPad... those require like 2.1amp, so that would be a 2amp usb charger.... I've seen 2.1amp home chargers, car chargers, etc... all because of the ipad I'm guessing.
Its not that simple. Any device that uses USB for charging can only pull 500ma, that's a universal agreement. To get around this each manufacturer uses a method of "informing" their device that it is connected to a charger that can supply more current (HTC shorts the data leads in the supplied charger I don't know what LG does). I have a 1amp car charger but it still only gives 500ma but the genuine LG charger gives an amp because the phone "knows" it can supply more.
I'm going to stick a test meter into my LG chargers over the holidays to see how the data leads are connected.

The charger i have is a noname brand. I bought it from walmart for 6 quid. It also came with a 2amp car charger and a micro usb cable.
Micro usb cables are not standardised like that. Ive never heard of such a thing at all. As far as i know most phones will "fast charge" if they dont detect a data connection and dump as much current as they can into the battery so you can pretty much present them with whatever current you like and the charge time will just get faster. There is probably a hardware limit to that somewhere in the charge circuit but i dont know what the limit is. 2amps is the highest power usb charger ive seen but its not exactly aomething i regularly keep an eye out for.

Slow charging is always better as this will allow the optimal number of battery cycles before the battery's capacity will start to degrade.
So if you only ever slow charge then your battery will have a longer life cycle.
I have had my Verizon Galaxy S4 since February of this year. I've been using the stock Samsung AC charger that came with it. It's always charged the phone pretty fast if I wasn't using the phone. It would charge about 15% in 20 minutes. Now it's only charging about 3 or 4% in 20 or 30 minutes. Now I didn't do anything different to my phone. I've been on this same ROM for over a month and this is just now a problem in the last week. My wife has the exact phone and charger that I have and when I use her charger it charges just as rapidly as mine used to, so I know it's not the usb port on my phone itself. I haven't dropped or damaged my charger at all in any way either.
Does anyone have any ideas about why this is happening?
If it charges fast on you wife's charger you've pretty much answered your own question.
Try using her cable with your charger, if it still charges slow then get a new charger.

Ok, I'll give that a shot. Thanks.
I had the same problem too ! Did a full battery reset and everything is going good now !
You have to charge it for 12 hours and drain your battery until your phone don't boot. Charge it and here you are !
Yeah these devices act funky every blue moon. My wifes didn't even recognize ANY oem charger for a week. Only detected others as USB devices causing slow charge rate. Removing dust, component cleaner, fresh install, all did no good. Eventually it just resolved the issue itself. All chargers work normally again.
change the usb cables
I also had the same problem before. I'd been using the original charger and usb cable and noticed that charging takes a lot of time than normal.
I found that it's on the usb cable. I accidentally found it when I used gsam battery monitor. It displays the current being received by your phone when charging. Using the original usb cable, it only gets around 600mah. I tried another usb cable (from a previous Samsung device) and now my phone gets 1,900mah (closed to the charger output of 2,000 mah).
Every since I changed the usb cable, my charging is fast now. Hope this helps.
I would try a new cable and Charger that is rated 2.1 amps or better if will be charged real quick

I noticed that using the Pure Nexus rom my charging time became significantly faster. In fact I can get a full charge from nearly dead in just over an hour. This is using the charger and cable that came with the phone.

How do you make full battery reset?
The charging rate is based on the output rating of the charger, which is determined by the resistance value between the Data+ and Data- USB pins. If you use a cheap cable with high(er) internal cabling resistance, that will throw off the detected charger output capacity rating, and knock you down to a lower charging current and longer charging time.
Also, one time, even with the original charger and original cable, I couldn't charge at anything more than the default USB 500mA. I ended up having to power off the phone, and power it on again, which fixed the charging current and speed problem.
Install this app & check if it is getting charged at max current; anything less than 1200 mA when screen on & 1900 mA when screen off, you need to change your cable or charger

I read somewhere that if you activate airplane mode the battery is charging faster.
