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.
You can find it by clicking here
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,
Initially i was thinking about getting a bigger 3000+mah battery or something but i've realized that i like the form factory of the GNex so i won't go for it.
Now i have 2 batteries the 2100mah and the original one that came with Verizon GNex.
I have looking for a external battery charger and found this
Has anyone here tried these, they seem to be the cheapest way to make use of both batteries.
Also the current wall charger i have reads the following:
input: 0.4A
Output: 5.3V=2.0A
Is the ebay charger in the above link close to the above specs as i don't know what they actually mean
Thanks in advance
I can't answer your first question but I can answer your second one.
Basically, your current charger is capable of charging the spare battery at a faster rate than the eBay charger.
The "charging rate" of 2.0A/2000mA versus the eBay charger's 0.8A/800mA.
When I'm looking for chargers, I prefer chargers that have an output of 1.0A/1000mA or greater so that my battery or phone is charged faster.
800mA is better than average. I'd find that acceptable.
I find most chargers have an output of 500mA. As a comparison, the OEM Samsung USB wall charger has an output of 1.0A/1000mA.
EDIT: In case anyone's worried about blowing up their battery using a charger with a higher amperage output then OEM, here's some reading material... bit.ly/xl2NPI
The only downside to using anything over 1.0A is that it may shorten the lifespan of your battery (the higher the amperage, the faster the charge, but it also comes with more heat, and more heat is bad for your battery).
What kind of wall charger are you using?
I bought a Cellet dock/charger. It can charge the phone and an extra battery at the same time. I mostly use it to only charge an extra battery. Sometimes it takes 4+ hours to charge a battery that is connected in the extra battery slot. WTF??? 4+ Hours?

I'm just using the OEM Samsung USB wall charger that came with my phone. It's sometimes listed as a "travel" wall charger. It has an output of 1.0A.
What's the output of your Cellet adapter (i.e. what you plug into the wall)? I'm pretty sure it has an output of 1.0A from what I've read.
Have you tried one of these?....IMO its better than carrying a couple of batteries around.

I am using the official HP touchpad charger, they are monstrous.
It charges the 2100mah battery from being dead to 100% with sync on in 1.5 hrs.
4+ hrs. is too long.
You can get on wallmart here or on ebay.
I haven't been this lucky with other chargers i've bought on ebay.

Ya i like these, but i would have to carry a cable and a battery at the same time, plus i don't have a tablet or any other gadget that uses microUSB charging.
On another note do these come with 2A charging instead of 1A??
if yes than i might just pick one up.
Alternative?
I've recently purchased this official charger. Does the job perfectly fine and is very small and sleek

I used Charger Timer, https://play.google.com/store/apps/details?id=com.vexedbadger.chargertimer , to test the rate of the 2.0a charger the note came with compared to a 1.0a samsung charger from my wifes note 1.
2.0a
Averaged a 1% charge every 73.85 seconds @ 1511ma
It would take 2 hours and 4 minutes to go from dead to fully charged.
1.0a
Averaged a 1% charge every 110.62 seconds @ 1008ma
It would take 3 hours and 4 minutes to go from dead to fully charged.
I expected the 2.0a charger to be twice as fast, but that wasn't the case. Either way I glad this phone has 2.0a charging and will buy more 2.0a chargers. The extra charging speed is a nice feature I don't think any other phone has.
If anyone else wants to run any tests to compare I would appreciate it.

now where is my 2.0a OEM car charger?
I don't trust those no name car charger claiming to be 2.0a.
1.0 vs 2.0
Mini-type or 2/3A recomend to use 1.0A, and large type or Sub-c recomend to use 2.0A.
Where is a good place to order an OEM charger?

Wife and I bought a new tab 3 10.1 and put it on the charger at 11.30pm, at 8.30 the next night it was only charged to 83%. Should it take so long to charge the first time? How long does a typical full charge take?
TIA
Are you using the stock charger? Cause I know when I plug mine in my USB wall outlet it'll take forever, when I use a USB stock or non stock adapter its fine
Sent from my SM-T217S using xda app-developers app
What creep138 said. The stock charger is rated at 2 amps. If you use like a phone charger that is rated at 1 amp then you are severely extending your charging time. Make sure the charger is OEM Stock (or one rated at 2 amps) and make sure the cable is the thicker cable that came with the Tab.
I can get 100% in a couple of hours after a good hard use. But if I run it over night on the charger, I most definitely get 100% in the morning.
what do you use to charge your sw3 ? i was charging it with an ASUS charger (100-240v) and after 20min the watch was very hot ! It's normal ? what kind of charger do you use ?
I use a genuine samsung charger (From a S4) and it gets hot too. I don't we should worry...
I checked the amps it draws from charger it showed ~.520 from wall charger, same as USB.
stupid design , its not easy to put the cable into the mini usb port

1. It is micro USB, not mini
2. There is always sacrifice in favor of ip68, I prefer waterproofing. But wireless qi charging would be good.
my mistake , anyway how long do yall get it fully charged? mine take pretty fast , can see percentage move up 1% in a few seconds , the watch has some heat up during charge .

Does it gets hot when charging directly from a laptop? The charger of a S4 probably deliveres around 1200mA where a laptop usually does only around 500.. A tablet charger even more..
I think quick charging (many times) is no good for battery life on long term! Except when the internal charging chip does limit it the right way. But when it gets hot[emoji6]
BTW Correct me if I'm wrong..

Mine limits it at ~540mamps from 2A wall charger. Also, never seen it really hot, warm yes, very warm yes, but not dangerously hot.
I have bought a Sony Smartwatch 3 for my husband for Christmas but I have no idea about power adapters and am afraid to use the wrong one. The Sony site simply recommends we use Sony adapters (of course they would) but they don't even say which one or what spec is required. In our household we have adapters for the following devices:
Nexus 4
Nexus 5
Nexus 7 (both versions)
Nexus 10
Different chargers have different specs and I don't know whether this is all important. Can I use any of these chargers with their cables (as I think the watch cable is rather short too)? I don't want to damage the watch using the wrong power adapter. I'm in the UK.
I got my watch yesterday and today I broke the plastic hinge on the charging port cover.
It's not completely broken thankfully just bent over, be careful they are not very strong.
2 hours to fully charge
It takes me 2 hours to fully charged (from can't switch on at all till showing 100%)
I am using the Samsung Note 3 Original Charger with the original Sony Cable provided.
Anyhow, this is my second time charging my watch.. have to monitor....
I used usb cable to charge my SW3, power-on from 0% to 100%. It took me almost 1 hour. At the beginning, the percetage was aurgemented very quickly. But at the end it took 12min from 99% to 100%

it is normal, the last percents are charged slower, that phase is called "topping off", uses low and/or pulsed current
It doesnt mater beacuse usb can power 5v devices so you can charge it ..... I would prefer the charger of nexus 5
5V, 3amps
the Snapdragon 400 has Quick Charge 2.0 that can draw as much as 3 amps. My samsung galaxy note 3 charger is only 2 amps, but already charges the watch fairly quick.

I'll take the difficult port with the ability to charge with a cable I almost certainly have close by any day. I would love to have Qi charging, but when I'm overusing my watch at work or on the go and need to charge, no problem. I have a micro-USB cable close by. I wouldn't have a Qi charging station with me at all times.
I use a right angled cable, makes it much easier to pop the cable into the port. And those people who have broken the cover or are having difficulty, are you gorillas or something?

Just thought of something else (that's actually on topic). I use the micro-USB that came with my Harmony 700 remote (I have 2 and both cables fit the same). It is actually a loose fit so it slides in and out of the Smartwatch 3 quite nicely. My girlfriend used to use it in her S3 but it kept popping out so I took it for my watch and found it works wonders. Since the SW3 seems to have a tighter fit micro-USB port, using a looser cable works nicely. It still stays in, but is so much easier to get in and out.
