    Default Very slow charging

    The gfs s5 is so slow at charging. After 2 hour charge it only goes up by 20/30%, I'm guessing this isn't normal? It is being charge by wall socket and not pc/laptop.

    Im fairly sure mine charges far faster than that. Are you using the original Samsung 2amp charger and original Samsung charging cable? I know some cheap cables can only manage a lower current than what the charger is supplying.

    Also have you tried charging it with the phone turned off to see how fast it charges, in case something is running the battery down a lot as it charges.

    Try restarting it.

    EDIT: It was okay for a few days but after a week it gave me trouble and even started getting hot. I exchanged it.

    Mine charges painfully slow on anything except for the charger that came with it. Last night I plugged it into that stock charger at 15%, cooked my kids mac and cheese, emptied the dishwasher and I was at 86% when I unplugged it maybe 30-45 minutes later. Was very impressed. However when using a car charger it absolutely sucks. Sometimes I will actually lose percentages if I am on it while charging lol.

    The S5 has an intelligent charging circuit that adjusts current flow to one of a very few acceptable levels (I actually think it's just TWO), no matter the rated amperage of your charger. I have charged with basically every USB charger I have (and I DO have a bunch), and the breakpoint on charging quickly seems to be at about the 1.2 amp point. When I am charging with the original charger or any 2.1 amp charger, the input current (as reported by the Galaxy Charging Current app) will start at 1800ma, then settle down at 1200ma. Anything less than 1200ma chargers (many are 1000 or 800, or even 650), and the charging current stays rock-steady at 500ma, which will almost triple the time it takes to charge your phone.

    For reference, on a 2.1amp charger, I charge at roughly 1% per minute, which jibes with the previous poster's observation of about two hours to fully charge. And, if your charger isn't the 2.1 amp sort, then it's probably settling at 500ma current and it will take approximately six hours to charge.

    Short story: Get a charger with more muscle.

    these showed up at my house yesterday, have not had a chance to play with them. knew i needed something because my old car charger kept up at best. they also have a corded version, but couldn't get a straight answer about cord length.
    just tested for 10 minutes, old usb2 cable, charging rate a tic over 1% per minute, twice what my old one did. cant speak on reliability or anything.

    i average a tic under 1% per minute. this adapter rocks too!!! (same speed as the oe adapter with usb 2 or 3 cables)

    hope this helps

    Quite the opposite experience for me, fastest charge I've seen yet. My average full charge from 0 is about 80 mins.

    are you using the orignal cable that came with the phone? mine was charging very slow too, but when i used the original cable, it got a LOT faster.
    or maybe the first 2 - 3 charges will be slow then it speeds up?

    Check the amps on your car charger. Some of them are very low and won't keep up while using GPS or Music apps. The bigger amp chargers are a little more money sometimes but well worth it.

    I've just finished testing my battery for usage and charging time, the usage for depleting the battery was playing with the different camera and video modes, browsing the internet, watching live streaming tv, listenting to the radio, watching YouTube videos and general messing around with the phone and settings etc, it went from 100% to 1% after 22 hours, 44 minutes and 36 seconds of use.

    I then plugged it in to charge with 1% left on it, I'm using the charger that came with the phone, it took 1 hour, 45 minutes to get back up to 100%

    These were the charging times if of any interest:

    37% after 30 minutes of charging
    71% after 60 minutes of charging
    95% after 90 minutes of charging
    97% after 95 minutes of charging
    98% after 100 minutes of charging
    100% after 105 minutes of charging

    this is on par if not identical to what I have seen with mine. I also charge through a USB 3 port on my PC that I added with a 18 in 1 card reader, which thankfully has a separate USB 3 connection for the Motherboard so teh USB 3 port has a dedicated direct connection to my MB. it runs maybe 20 mins slower to fully charge and is probably caused by the connection path being broken in to 5 steps (extra 1 due to a USB 3 extension cable I have to use to be able to reach the connection to take the cable with me), vs. the 2 point connection from the wall adapter (phone =1 adapter =2). strange part is that my MB USB 2.0 ports are 1500mAh ports, I paid extra for this board over one I liked better, because of this feature, but the USB 2.0 ports do not charge as fast, even on my older USB2 phones. What I learned from having an LG spectrum is taht the chip in the phone actually downgrades to the slower charge speed if it does not detect the OEM connection (cable and charger), although some other charges must have the correct chips as they would charge at full power, but that was only 1 in 7 chargers that I had at home besides the OEM one.

    Definitley the fastest charging phone I've ever used, full charge from 0 to 100% in somewhere around 70-80 minutes, my S2 used to take like 3+ hours with half the battery size, my iPhone 5S and 5 are way slower as well.

    Mine goes from 15-20% to full in about an hour and a half. Charges really really fast!!

    I'm seeing the SLOW charge too.

    Put it on charge before going to bed at around 10pm. It was at 20%. Now, at 3:30am, it's only at 45%.

    I'm using the charge cord that came with the phone, plugged into the USB port on the laptop. I'll try using the wall charger to see if that helps, but that would be a real PITA to have to do all the time.

    usb is the slowest possible way to charge your phone, next to maybe a hand crank charger, lol. use the one that came with the phone for a comparison of charging speeds.

    Something is wrong then. I was at 57% and was going out and put it on the charger for 15 minutes and it went up to 71%.

    That's the normal time to charge using a regular USB port on a Computer or a Laptop, if you were to use the wall charger that is a 2.0 amp charger using the 3.0 USB cable you will see that it charges your device a lot faster, I've charged my from 1% to 100% in about 1.5 hours.

    If you are forced to use the Laptop, then at least find if your laptop has a 3.0 USB port and together with your OEM Cable you will see that it charges a lot faster than with a regular USB port.

    What this dude said. 90 minutes for a full charge from 0% to 100%. I've noticed it's around or slightly a bit more than 1% for every minute on a wall charger.

    Uhhh all phones charge slow on USB with a laptop/computer. It'll be faster if you have a usb 3.0 port. Wall charger is going to be a lot faster, for obvious reason, mines about 80-90 minutes from dead to 100% which is ridiculously fast charging for a battery this size.

    Actually, if this phone takes as long as it took to go from 20% to 45% using the USB 3 port last night, it'll be the FIRST phone I've owned that charged so slowly. All phones will charge quicker with the wall charger, but this was crazy slow. Since I had completely powered the phone down and re-started before throwing it on the wall charger, I'll try the USB next time it needs charging to see if the shut-down/re-start might have had some effect on the faster charge time.

    Using a regular Micro USB cable it will charge slowly.

    Using the Samsung Wall-charging cable it'll charge from 10% to 100% in about 1.5 hours.

    Are you using the charger and cable that came with the phone?

    Mine charges really quickly.

    Does about 80% in an hour.

    I use the wall plug that came with it, a 1.5m Belkin USB extension cable and then then micro usb that came in the box.
