Hey developers, is it okay to charge the Samsung Galaxy S3 (SGH-I747) with a block charger from Samsung Galaxy Tab 10.1 (GT-P7510)? When I do use it, it seems to charge the phone's battery way faster than the original charger. But I have a feeling that it might not be too good for the battery. The tab's charger is 2.5A and the phone's charger is 1.0A. So my question is: is it safe to still keep using the tab's charger to charge my phone? I want your guys' opinions. Thanks.
Yes that charger Is fine. It charges faster because it's a better charger.
I think the stock charger is mislabeled. It says 1a but doesn't charge as fast as my blackberry or iphone charger.
Stock charger is crap.

Yup, should be very safe. I use a BlackBerry PlayBook charger to charge my phone quickly. It's rated at 2A.
thanks guys! also, when I take the phone off charging, if it said 89% at the moment I unplugged the cable, it is still gonna go up to 90% haha. I think the charger is so strong that the battery still absorbs the charge for a while even after the charger is unplugged. Interesting phenomena.:good:

.... Or it was about to change to 90 percent... And it does as you unplug it... Trust me, it's not charging at all when it's unplug, the heat left in it might give it that 0.1percent boast but it'll set down to 89 quickly

Hey people,
Before I went out and bought a car charger and second wall charger, I was wondering if you guys knew what the fastest ones were. I was using my friends car charger the other day and it literally did almost nothing for 20 minutes. The battery went up 1% every 15-20 minutes or so.
It's probably an issue with the cars 12v port, not the charger itself. No matter what your phone should charge around 3.7v. If you plug in a charger that has a higher output to try and speed charge it the phone and the battery have built in protection to keep it from charging above the recommended 3.7v. So just buy a reliable cellphone charger and don't fall for speedcharging gimmicks

I remember back when the iPad first came out there was a rumor that using an iPad charger to charge an iPhone would charge it faster, but the device only pulls what it needs (if it's designed well). I believe charging a device at a lower voltage may make it charge slower, but you can never speed it up unless the battery specifically possesses control circutry to do so. See http://en.wikipedia.org/wiki/Battery_charger#Fast.
Charging time for my battery is pretty slow. I takes more than 3 hours from 10% to full! It doesn't matter if it is chraging with the carger or via USB. Is this normal with the Nexus? I had Htc Inspire 4G, and the charging took 2 hours top!
*if i use the phone while charging e.g. play some game, the battery is still draining instead of charging.

You should get better results with an A/C charger but I've seen some wall adapters still read as if its plugged in via USB. You can check by going to settings >> battery while it's plugged in and it should read A/C charging.

What is the max current (mA) the charger you use can provide? Divide the capacity of your battery (in mAh) by the charge current. That is your approximate charge time in hours. I believe most AC chargers can charge with 1A, so a stock GSM battery of 1750 mAh should take less than 2 hours from being discharged to fully charged. Mine does.
The behavior that the GNEX will discharge even while being charged with a non AC charger (including car chargers) when gaming/navigating is not uncommon.

Yes, it's reading A/C charging, but the charger is from alcatel with 400mAh output.

I've been charging it with Alcatel charger with 400mAh output. I'll try with Samsung charger with 5.0V output which says it's equal to 0.7A because I don't have the original (I think i have used it before, but i dont recall that it was any faster).
Could be kernel related issue, since there is an option to "Fast charge" via USB and it's enabled?

its not likely a kernel issue unless you are on some experimental one, but you would be able to easily find out by looking at the forum cause others would have the issue. And if you didn't know the Fast Charge option is to make your phone think its hooked up to a wall port if you are charging from your laptop or if your car charger is only being used a usb port thing.

It's franco kernel, nightly 251, pretty stable from what i've read in the thread. Also, I know what does Fast Charge option do, but I thought that somehow it messed something up. While I was googling for answers, I found some forum, where was mentioned the battery chip that is regulating the power it's using to charge the battery could somehow get messed up. Maybe I have bad batt.
mine battery too takes 3 hours to full charge using stock samsung wall charger. I'm using stock rom and kernel.
Mines takes 1 hr 30 minutes tops with fast charge

You are using a 400mA charger, the gnex comes with a 1A one. Go figure.

That is because the car charger most likely did not short both the data pins out, therefore you notice the discharging phenomenon because the phone will only take in 500mA without the data pins shorted or with kernel fast charge enabled. How is 500mA going to keep up with navigation, GPS and all other tasks?
Beamed from Maguro
Also realize that your previous phones battery probably had a lower capacity than the gnex therefore coming from 2 hours, 3 hours isn't that bad for charging a bigger battery

As has been stated get a GOOD quality charger. I might be weird but both my car charger and spare outlet charger came from Verizon. At least when i have had something not work they have been more than happy to open another and fully test in store for however long it takes. Sadly, my last car charger broke and I am too lazy to get another, my solution was to use a car inverter since I charge my other devices regularly on long trips. Plugging in a regular wall outlet from, oddly enough Motorola, does the job just fine. Alas, the majority of chargers my coworkers leave out are for lesser phones and will not even register on my beastly Nexus.
However i think i damaged my charger (original 1Ampere samsung wall charger) when i've been in Malta (i'm from Italy) last August. Before the holyday my nexus charged in 2 hours or less. During the holyday the charger heated a lot more than when using at home and now the charging process lasts about 3 hours. Also, when i connect the charger to the wall (even if the phone is unplugged) i hear a low almost-ultrasonic whistle.
I hope the damage isn't the battery.

I have the same problems too. I tried to use other charger, but the problem still remain. My charging process lasts about 2.30 h to charge from 55% to 100%. I really hate this because I need to charghe my phone faster. Please help us. (I'm italian too).

Thank you very much. And the effective result is really a faster charging? Does it works good or not?
Does charging my phone directly with the usb port charge the battery better than when a battery is charged on a wall charger? I've been having bad battery problems with all. 5 of my batteries (including a 3500 mah one) and I'm starting to think that when I charge my phone whatever battery is in it last longer than if it was charged on the wall charger. Can anyone confirm that this may be true?

I recall reading somewhere that charging through USB has a chance of overcharging the battery because the wall charger has an auto cutoff when the battery reaches 100% and the USB does not. This may have something to do with possible better battery life when charging through USB. Have you tried draining the phone all the way down to 1% or until it shuts off then charging it to 100% a couple times?

I pretty much do that because I keep the battery in until my phone dies then just switch batteries. Whatever battery ends up in my phone by the end of the day gets charged by usb in my phone and any other batteries that died during the day get charged on the wall charger. But what your saying may be true because on the wall charger usually I find the batteries only 96~98% never actually 100%. Ill test it out and see what happens. Anyone know of a wall charger that works really well?

It would be nice if I could find the articles I read on the matter for some weight, rather than just my comment. But anyways....
The battery is never at 100%; that is for safety reasons. Whether USB or wall charged, it won't hit 100.

Can anyone tell me why it takes so long to recharge my phone ?
I use a charger cable from my computer (usb) to phone while at work --- then I also use it at home too.
Is it only the wall charger that does it fast ? not USB/laptop/computer ?
Last night it took me 10 hours (phone was on but I didn't touch it for 10 hours - internet/wifi/3g was OFF)
why does it take 10 hours ?
Is something wrong with the phone? battery? or is it the charger ?
USB only has a small amount of current that goes through it. Enough to power small USB devices and no more. I believe it's around 500mAH. But your phone is always drawing power, so the excess is what actually charges your battery. Your wall charger is 1000mAH which means there is plenty of current to charge your battery even with heavy usage.
Tl;dr: USB is weak and 10hrs is normal. Wall charger is much more powerful and faster.

damn thanks for the great reply.
Further more, I was at my friends house once, and he has a black berry (same charger as my SGS3) and he passed me this cord to charge and it honestly charged the entire phone from 5% to 90% in like less than an hour...
not sure wtf this was but is it possible ? is it bad for the phone ? for the battery ?
10 hours is not normal. And the average wall charger that comes with your phone is 750mAH, not 1000. The 1000mAH chargers are quick charge ones.
The fact that the blackberry charger worked well on your S3 tells me that you should get a new charger.
where does one find one of the quick chargers to buy ? (1000mAH)
you can find all sorts of chargers on amazon. you can find inexpensive ones at walmart too. i would recommend buying a samsung charger for your samsung phone. hold onto the one that came with your S3, even if it takes forever to charge. just use it to connect to your pc for file transferring, odin, etc.
Even though charging quickly seems good but if you can afford the time then use the one you already have z charging too quickly affects your battery health negatively , a slow charger will make sure your battery stays healthy for a long time , mind it by slow I mean a 750 mAH one not a faulty one in case yours is faulty .

The S3 charger is 1000mAH. I have two of them that came with my phones. And anytime I connect my phone to my computer I can leave it connected for hours and only charge a few percent. This phone just draws a lot of power.

thats interesting because i have 4 samsung chargers. 2 came with my old S2's and 2 came with my 2 S3's. the output on all 4 is 700mAH. i got robbed. of course, connected to a PC the output is max 500. even at that, i still get a better charge than a few percent when connected to a PC for hours.
I just bought the LG G3 ATT version and I absolutely love the phone! However the charging time on this device is horrendous compared to my Note II which has a bigger battery. Please help!

Are you using the stock charger and cable? If not, what is the Amperage of the charger you're using? Are you charging from the wall or your computer?
I get a charge from 10% to 100% in around an hour in the UK.

Anywhere from 3-5 hours. Also if i'm using the device while charging it almost feels like its staying on the same level, something that I haven't experienced with other android devices.

I feel the same about using the phone and charging when playing games. No idea how long it takes to charge it tho, doing it while i sleep anyway.
I'm going to go wireless charging but sometimes I'll turn my phone off and give it quick charge since it charges faster. I know some people don't like to do that though.
the first thing I would check is that the usb cable is plugged all the way into the mains charger. When I first got mine it kept saying usb charging is slow, please plug into a mains charger, which I thought was weird as it was plugged into the mains, but on closer inspection the cable wasn't all the way into the plug, so it was thinking it was using a pc connection. plugged it all the way in and it was charging like a demon then.
Same freaking problem. It discharges 100-0 in 6 or 7 hours, with 1:30 screen on time, and recharges 0-75 in three hours. Have you managed to fix it?
