Not sure if this is an issue, or if its standard. But here is what im facing.
A charge off the wall will get my Tmobile SGS2 to a full charge (from around 15%-20%) with the stock plug and cable in about an hour to an hour and a half. However charging from my laptop or from a car charger im only getting a total increase in battery 15% in an hour. I tried to use the stock cable with the laptop and got about 25% in an hour and a half. I tried to use the stock cable in my car and only got 7% in 45 minutes.
Anyone have any ideas?
When charging from the car or from a laptop, the power is limited to what the cable/charger can supply which might not be sufficient for the SGS2. For the car charger, you can try buying one that supplies more amps, but for the laptop, theres really nothing you can do, as it is limited by the USB cable itself.
Do you mean the USB cable or do you mean the actual plug & internal workings of the laptop? because i have tried several cables. And just also remembered that i tried the stock cable as well with crappy results.
you can buy a 2A charger, and it will charge a lot faster, that's what i use in my car
at home or office, i just use the regular charger, as i always carry extra battery packs
When you plug it into the laptop it only gives out a limited amount of amps unlike the regular charger that came with the phone. The one that came with the phone regulates the charge so that it doesn't overcharge your device or anything. The laptop USB plug is supposed to be meant for peripherals like a mouse and stuff so it doesnt give out that much amps, therefore charging slower than a regular charger.
I use the t-mobile rapid car charger, It can charge this beast in about 45 minutes. It also has a 2nd port for a 2nd device.
Deebo took your bike too?
Really?! I've never seen my charging current go over 700 mA, even with a 2 amp charger.
I'd happily give up some long-term lifetime for faster charging.

They have a home charger too that's a home charger plus car charger in 1. I use them in the cars but they're great for trips cause you have a 2 in 1 charger.
With 3 batteries and a external charger though, I never need a home charger and haven't even put this on a charger yet.
Just as most of the others have said here, the charge is going to be limited to what the source can put out. If you get another charger (2A charger) then it will be able to charger faster but you also want to be careful with using after market chargers there are some that can negatively affect your battery by overcharging which is when the phone gets fully charged but the charger does not ever stop with the flow of power to the device.
Ok Thanks all.
Guess i need a new car charger and something for the office.
Also did some crawling through "Mother of all battery life" thread found some good ideas there for making this thing last longer on the charge its got.
Im having the same problem my fone takes forever to charge...im pluged into the wall using the charger in the box n it took me no joke 7 hours to charge my fone!
Im on it rite now as its plugged i to the wall n im losing power instead of charging...i tested the voltage n its fine ...is tgere anythin i can do?

I, myself, actually haven't used the OEM charger that came with the phone. Although I did notice it is quite small and the phone battery is a 1850mAh (larger than normal) that might affect the charging rate. I am currently using the old HTC charger that came with my Sensation and it charges fully in about 2 hours. If you want a charger that charges your phone in an hour and a half, I recommend going into a T-mobile store and grabbing the Wallcharger they sell. It charges 33% faster than OEM chargers and does not harm your device nor kill your batteries.

Exactly same problem as OP.
OEM wall charger charges phone to full in couple of hours but laptop USB or car USB is doing at 10% / hour assuming you don't do anything on your phone but just leave it there to be charged. Otherwise you'll be losing battery rather than being charged.

As explained in previous post, this is due to limitations in the laptop USB drive and depending on what car charger you have, the phone might suck up more juice than it is able to provide.
so this is nothing a kernel or any other tweak can fix?

Yes, or if you have like an old microUSB charger from HTC or another Samsung phone (Samsung Vibrant) you can try using those.
the 2A chargers from BlackBerry are the best
So, you guys are seeing the phone draw over 700 mA (when the charger is capable)?
If I use my iPad charger (2A), I still top out at 700 mA, and the ~4 hours that go with it. :/
Even my 1A car charger tops out at 700 mA, that's why I thought it was a hardware issue.

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

how do I check the quality of the charger?
Recently I've noticed that my Gnex battery will LOOSE charge when plugged into any power source that isn't the Samsung charger. Weird right? If i plug it into my laptop, car charger, an LG wall charger the battery will drain. It has happened multiple times where i've hit 15% battery life and plugged it into my laptop or car charger and it will loose a 1% about every 2-3 minutes.
I've switched roms with no luck. What is going on?
Its not uncommon for this to happen from a laptop port - especially if the phone is being used while plugged in. The USB output on laptops is likely not very high.
Check the amperage of the alternative chargers you are using. If its too low, they won't be able to keep up. Make sure its the same as what the stock Samsung one puts out. Can't recall its exact specs off the top of my head...
Laptop and car charger are 500mah or less. Your phone is using battery faster that it's recharging. Nothing odd about that.
charger
I'm charging on my laptop with a cable of blackberry and no loss there. Charging with at the wall I'm using only samsung utilities so I can't help you out there..
Despite that I don't understand what that has anything to do with rom's?
My phone is having some issues charging. Firstly I took the phone to Canada for a fortnight from UK. The phone charged normally for about a week and then one day the battery got very low (3%) and the phone would take a charge. I dont know if this issue was caused by using a plug adaptor or by letting the battery run so low?
When i got home the phone wouldn't charge from the mains initially, but i was able to get it above 15% using a computer usb port and from the on it took a charge from the mains.
As of today it is now playing up again, it wouldn't take a charge from the mains overnight, but I think it is currently charging via my pc, though it seems to require the cable be held at a tight angle.
My wifes galaxy s2 had the same problems as my note 2 in canada, but we were never able to charge it when we got back to the uk. I am looking into replacing the usb port for the S2, so i was wondering if this was something I should be doing for my note 2?
How long is the Samsung Warranty? (phone is 18months old)
Are the usb ports easily replaceable?
Anything I should know before doing this?
Whenever i put my G3 on charging it charges like it's connected to a USB cable and the charging becomes so slow... :crying:
So i keep pluging and unpluging the charger until it charges regularly. (I'm using the original charger that came with the phone)
I tried a different cable and it worked, then i tried the same cable but with a different charger and it also worked .-.
This thing is driving me crazy xD every time i need to charge the phone i plug and unplug the charger more than 20 times until it chrges regularly and that charging sound come :laugh: the sound makes me feel happy
I added some pics to help
Please any help
Probably a bad charger
Wouldnt hurt to take into a service centre to make sure that theres no problem with the Micro USB port
