    Default Samsung Galaxy S3 charging problem

    Hi all,

    Hope this is posted in the right forum: I have an unlocked, network-independent Samsung Galaxy S3, and I couldn't find a forum that was specific to this situation so I hope this will do.

    A couple of months ago (after not having changed any configurations or apps) I noticed that the battery does not charge fully when the phone is on. If it is off, it charges as normal. If it is on without WiFi it charges at about 1% an hour. If it is plugged in with WiFi on, it discharges at about 1% per 30 minutes.

    I have switched between three different cables, I have switched between three different chargers AND the PC with three different USB sockets, I have bought a brand-new official Samsung battery. I have cleared the system cache in recovery mode. I have cleaned the USB port on the phone with alcohol and a q-tip. I have cleaned the contacts on the battery and the inside of the phone in the same way. Nothing works.

    At the moment I'm switching between batteries and using an external charger, and they charge just fine, but the situation is a huge pain in the posterior.

    I have googled this issue and have found hundreds of people reporting the same problem, all in the last couple of months. I'm a bit bemused because I haven't upgraded (and I don't get auto-upgrades since the phone is rooted), so it seems a bit weird that this is suddenly happening to many people.

    Most threads on this subject suggest that there is a problem with the cable/battery/charger. Well I think I've been thorough in checking all variables. What have I overlooked? Does anyone have any more suggestions other than the ones I have tried (gleaned from the many threads I've found about it)?

    Thanks!

    I should mention, though it's rooted it has not been flashed: it has official Samsung 4.1.2.

    Welcome to the forums! Being rooted should not matter in this case.

    For clarification, are you noticing the slow charge only when its connected to a usb port, such as PC? Or does it also occur when plugged into the wall outlet?

    Generally, devices will charge slowly or possibly even discharge while connected to usb power sources because there isn't enough power output to keep the device charged.

    Both. I know the wall outlet provides a higher charge, but it used to charge fine with the PC too. Now it has the same problem with both.

    That's odd. Other than trying other wall outlets, which I'm sure you already have done, I have no other suggestions. Have you considered taking the device back to the carrier and see if they can help troubleshoot. It could be a hardware issue, but that's just a wild guess.

    I am facing the exact same problem since like a week or so and I don't know what to do, I have pretty much tried everything even downgraded my OS but nothing worked, do tell me when you find a solution because I feel like giving up

    Yeah, I've tried probably a dozen different outlets and three or four chargers.

    Like I say, there is no carrier. It was bought outright and is network-independent. I don't really want to take it to Samsung as it'll be gone for weeks...

    This is not an isolated problem however. If you Google "s3 charging problem" you will find hundreds of people with the same issue, most of them reporting it in the past few months. In fact I see there's another one on the front page of this forum right now.

    Since it charges fine when it's off, and all the accessories are working fine, I am strongly of the opinion that it's softwar related. I had hoped that the issue might have been addressed and diagnosed on this forum at some point... Oh well. Thanks anyway!

    Sorry to hear that you're having exactly the same problem. Until someone even diagnoses the problem all I can suggest is to buy an extra battery and charger and keep rotating them, like I have to do.

    Jimblywee,
    I'll agree with your assertion that there's been a rash of similar reports lately.

    And that in common is the observation that if the phone is completely off then charging takes place at a normal rate (which suggests to me that there's nothing wrong with the micro-USB port or the actual charging circuit).

    The only conclusion that I can draw is that the OS is somehow mis-managing charging, but I don't know diddly about how that is implemented or what the fix could be.

    If you were of a mind to, you could be a guinea pig and do some experiments:
    - use Kies or Odin to reload the stock firmware
    - if that doesn't pan out, backup the /efs structure, then wipe the phone completely and reload it
    It obviously won't do me any good to try these things since my phone isn't having the problem (yet).

    P.S. For all I know the charging circuit is different between phone completely off and phone on - if I had money to throw at the problem I'd suggest buying a wireless charging solution just to see what happens.

    I have a Note 2. With the same problem. It start about 2 weeks ago. I think after a update.
    My phone only will charge up to 56% at night. It wont go over that percent. Also the charging is very slow. I have 5 batterys that I tryed chargin on my phone and the same thing.
    Then I have a external battery charger and the batterys charged to 100% fine.

    Seems maybe the port/phone is not pulling enough power to chargr it to 100%.
    Does anyone know how to reset the battery log? I remember doing something like this acouple yrs ago on my old phone.

    this is pissing me off alot.
    Hope to find the problem

    Heh heh - and of course I left out the obvious: contact your carrier and/or Samsung - I'm sure they'll be very helpful. :rolleyes:

    Thank you! At the moment most of the responses suggest hardware issues, but I do think it's something else. At least your concurrance reassures me that I'm not going mad.

    - use Kies or Odin to reload the stock firmware
    - if that doesn't pan out, backup the /efs structure, then wipe the phone completely and reload it
    Well I was thinking of trying the leaked 4.2.2 but that might make things a lot worse. I have no idea how to do the second!
    It obviously won't do me any good to try these things since my phone isn't having the problem (yet).
    Long may it not!
    P.S. For all I know the charging circuit is different between phone completely off and phone on - if I had money to throw at the problem I'd suggest buying a wireless charging solution just to see what happens.
    Don't the wireless solutions have a gizmo that enters the same circuit though?

    What I do is I have installed an app known as Galaxy Charging Current *lite* and it shows me the charging speed of my charger and it varies with time to time or when I unplug and plug back the charger so I plug and unplug the charger till the MAX value in it becomes 700 or 800 so then the charging time reduces somewhat, still not a solution but it is working for me till now.

    Thanks, I'll check out out. I'm right in thinking it just measures the power, rather than does anything to it?

    Yes, I'm sure that the wireless charging solutions connect to the same charging circuit at some point, but they eliminate part of the path (involving the micro-USB port) so I figured it would be worth a shot (as I noted, if I had money to throw at the problem).

    Jimblywee,
    Since your phone is rooted you could take a look at Battery Monitor Widget: - it apparently has a way to reset the battery calibration data. Perhaps that would help? (Picture of dying man grasping at straws goes here.):banghead:

    Angry Re: Samsung Galaxy S3 charging problem

    I am about to throw this thing out the window, I have bought several car/outlet chargers and can't seem to get a "solid" connection in order to charge the phone. New Battery too, this just started within the last month. Right now my battery is dead and I can't get it charged. This morning I woke up with an "android" looking green thing on it that said "downloading". I don't have a clue what the heck its even downloading. Any idea? Whatever it is downloading isn't going to download properly with the phone going on and off.

    P.S. I don't root my phone or any of that stuff. I'm clueless what all that means

    I have the same problem with my note 2. It will only charge to 67%. This also started a month ago also. It must be something with the android OS.i have 5 batterys and many charges and it wont charge also. I have 3 external chargers that I bought online to charge the batterys and they charge to 100%.

    Did u try goin to your phone carrier?

    Iam gettin pissed off also.
    Everyone with a iphone is telling me to get a iphone but after there update to the new IO7 there batterys drain fast also and they charge there phone mnay times of the day. Also I hate apple/rip offs and there storage problem. So not worth changing over. Hopefully someone finds the solution to this.

    That's generally not a good sign - in order to get out of Download mode you'll need to pull the battery. You should leave it out for a couple of minutes, then put it back in BUT DO NOT TURN THE PHONE ON YET.

    With the phone still off, connect a charger and you should see a battery graphic showing the phone charging. Let it charge to at least 50% before going on.

    Note that if you don't get a battery graphic, or if you have to wiggle the charger cable where it plugs into the phone to get the phone to charge, you either have a problem with the charger/cable or with the micro-USB port on the phone. If you've tried other chargers/cables and have the same problem then it's the port on the phone. At this point there are only a few options:
    1. Purchase a wireless charging solution, which bypasses the nonfunctional port
    2. Get an external charger and swap batteries in and out
    3. Get someone to replace the port (iffy at best)
    4. Send it to Samsung for repair
    I'd suggest the first option if it comes down to one of those choices.

    If you manage to get the battery charged, go ahead and turn it on. Hopefully it boots normally - if, instead, it boots up in Download mode, come back here for the next steps.

    Just to update, I cracked my screen and had it replaced. I wondered if there was too much drain from the old screen which might have been causing the problem, so this was the ideal circumstance to check this hypothesis.

    No.

    I had the phone on charge all night with screen off but the wifi on. It was at 80% when I went to bed; when I woke up it was at 15%. I turned it off and plugged it in again.

    It recharged to 100% in 90 minutes! It conclude must be O/S related. Holding out for 4.3 in the faint hope it may fix the problem.

    having the very same problem here, it just started to happen randomly, i didn't installed any new app, or made any changes to my actual configuration on the phone, it does charge too slow now, something it even decharges while taking charge what and irony, sometimes it does charge at the normal supposed rate, but most of the times its really really slow, I've as well tried with many different chargers getting the same results, tried another battery as well, this is driving me nuts, coz my phone is most of the times dying or asking to be connected to a charger
