How to fix a phone that won't charge properly

Kris Carlon
56

Some of you may have suffered from this problem and rushed out to buy a new charger when the solution was at hand with only a tiny bit of effort and only a little bit more know how. This has been one of our longest running forum topics, appearing over a year ago in answer to the problem that the Galaxy Nexus wouldn't charge. One of our industrious readers, Marchino, shared the first fix and has had pages of thanks dedicated to him ever since. Here's five tips to fix a phone that won't charge.

The problem

Either your phone won't charge at all when it is plugged in, or the connection drops out or only charges very slowly, sometimes only just faster than your device's battery is discharging. This is actually a very common complaint, and one I suffered from with a device myself. There's a few things that could've gone wrong.

DIY USB port fix

The quickest and easiest, and often most successful, solution is simply to do a little DIY repair on your actual hardware. The problem is quite often that the metallic surface inside the USB port and the microUSB charger are not making good contact, either through a manufacturing defect or because of the continual plugging and unplugging of the charging cable. All you need to do is shut down your device, remove the battery if possible and use something small, like a toothpick, to 'lever up' the little tab inside the USB port on your smartphone or tablet. Do so very carefully and gently, then reinsert your battery and plug it in again. Nine times out of ten this is all that is required.

Switch cables

The flimsiest part of a charger is of course the cable, not the adapter that plugs into the wall socket. So if your device is having charging issues and the previous solution hasn't helped, you might have a faulty cable. Before you rush out to buy a replacement, just grab a spare USB cable from another device and try it instead. Quite often the cable will fray inside because it is constantly being curled up, stood on or whatever. Rather than buy a complete new charger you may only need a new cable. Likewise, if the cable doesn't seem to be the problem, check the wall plug adapter, that may be the issue instead. Also, check the same charger/cable combination on a different device and see if it works normally. iPhone users have their work cut out for them with the incredibly flimsy Lightning Port charger.

Clean up your act

Sometimes the reason a device is not charging correctly is because there is something lodged in the port, or there is just a lot of debris blocking the connection. Pocket lint, dirt and other minute rubbish can get into all sorts of nooks and crannies on a smartphone, so take a look to make sure there isn't something lodged inside the microUSB port (or in the charging cable either). Of course, also make sure to never charge your phone near water or in excessively hot or humid conditions. Also, do not overcharge your device, charging overnight when your battery only needs 2-3 hours is a very bad idea and can lead to a battery exploding or damaging your phone.

Replace the battery

If your device is old, or seems to be acting very strangely where the battery is concerned, you might have a defective battery. If your Android has a removable case, take the battery cover off and ensure the battery isn't bulging or otherwise deformed or leaking. If it is, remove it immediately and clean the area carefully to avoid corrosion. If your cover is non-removable, you can lay the phone on the table and try spinning it, if the battery is bulging it will spin (this could just be the design of the phone though too, so don't be alarmed). Replace the battery with a manufacturer original or respected third party power source. A new battery should last at lest two years before it needs to be replaced, although this depends on the number of charge and discharge cycles. If this seems necessary too soon, check your warranty, you may be eligible for a free replacement.

Up against the wall

Charging from a wall socket is always going to charge faster than via PC or laptop. Likewise, the current is different, with a wall socket putting out potentially double the power of a laptop or computer. Of course, if you're using a different charger cable and adapter than the one the phone came with, it might also be the case that your charger is not sufficiently powerful for your device. For example, if you're using a charger that came with a Bluetooth headset it may simply not have the guts to be able to charge your phone. There might also be a problem with your wall socket, but that is much less likely. To charge faster, switch on airplane mode or turn your phone off.

If all else fails, just double check that you actually have the power point switched on. That is the first thing they will ask you if you call your manufacturer for help, which might need to be your next step if none of these solutions have worked for you.

    I have this a lot with my phone (Rugby Pro) I don't think it's the cable or port. In my case it seems to be the charger that came with the phone is faulty, but it's intermittent. I use the charger from my old Samsung (now my wife's)

    I've had problems with a Nokia E7 phone. These micro USB connectors are flimsy, surface mounted devices. I believe that the problem I had was a poor solder joint to the board. If I stressed the connector toward the front side of the phone it would charge. Since this phone is a real pain to take apart my solution was to buy another phone, since Symbian devices are orphans or neglected relatives. I bought a ZTE V998 smart phone. The connect on it is tight and rigid.

    Great info. One correction, I believe it's the current that is different between wall power and a computer USB Port, not the voltage which is always 5V. Btw can we get an article about super fast chargers? I heard they sell chargers that can charge your phone fully in minutes! Are they safe?

      Hey @James, I stand corrected! Made the change, cheers for that. That's a good idea on high-speed chargers, we might have to see if we can get some to test. I have never used one, but am pretty interested in the future of the supercapacitors we keep hearing about that can do it in a minute or so.

    Has anyone seen a multiple USB charger that delivers 2 Amps to each of, say, 4 USB sockets? Or a mighty one of similar output that one could jam a USB splitter into?

    The charger that came with my Nexus 7 is now v-e-r-y slow. Brushing and tweaking ala the above has made no difference. Is this a rare occurrence with these (Asus) chargers?

      Maybe the tablet has supersized mAh compared to phones. My wife complains her GS4 takes long to charge, but I remind her that thing has more capacity than say, my Nexus 4.

    Yup, a Nexus has a big battery and it takes longer to charge than a phone does. My pont was just that it now takes much longer than it did when it was new and I was wondering if others experienced this too.
    I'm still hoping that someone has seen a multi socket, multi amp charger that can handle multiple big devices.

    this problem is happening to me now this is the second time the first time I took my phone (htc evo 4g) to the store and they said they fixed the usb port. now when I charge it the notification light or the lightning symbol that appears on the battery icon that show that it is charging usually don't appear. its like my phone charges when it feels like it. sometimes it will just say discharging but I will admit I used to sleep with my phone charging overnight almost everyday. don't know if its the usb port or battery someone help please

    I've been having a charging problem with my Samsung Galaxy3 for a while now. It seems like it's discharging the charge faster than it's taking it in. I have tried different cables as well as all of the solutions listed above. I even went out and bought a Duracell charging pad so I could try and charge it wirelessly. When I use that, it will start charging, and then it will vibrate to let me know that it has yet again stopped charging. I have tried a couple different places using the wireless charging pad, so I know it's not the wireless connection either. I have even changed the battery. Still doesn't want to charge. So very frustrating. If you could help me figure out why I'm having such charging problems, I'd be so grateful. As would my phone, seeing as how I'm now just barely holding myself back from running it over with my car :)

      So it's been dead the whole time? That's a problem. If none of the above tips have helped you might need to take it to a service center or repair man. It's possible there's a loose connection somewhere or the battery has just died completely, but that would require an expert to resolve.

      When you say it indicates that it is charging do you mean the LED lights up or the little charge icon on the system bar shows it is charging? You could try recalibrating the battery with an app called Battery Calibration (by NéMa), but it requires root permissions.

    Hi there, I've just ran into this problem last night, it only charged up to 80 something percent which was enough to get me through the day but now it won't charge at all, I've tired several different cords and nothing. I tried the cleaning thing and still nothing. Kind of freaking out, I need my phone!

      Hi @Charlotte, unfortunately when it gets to that stage it's possibly time for a new battery or professional advice. I'd say try another battery, clean all the connectors and do the cable swap but it sounds like you've done all these things already. If the phone won't even power on I'm kind of out of solutions and you might need a technician with proper tools to isolate the problem.

    My Samsung tablet 10.1 for a couple of days now restarts on it on several times a day. This started when I was watching a movie on it and the movie kept hanging/freezing up at certain parts til my tablet froze and that's how the auto restart issue began. I have deleted the movie and a few apps to free up space but yet the issue persists.

    Thanks for the wonderful post. I am facing a issue with Samsung Duos. It is charging when connected by a USB to the computer but when the same USB is connected in the wall power socket of the phone it doesn't charge. I have used different chargers for the phone and also different phones for charging on the same wall charging point but the same problem persists. Why is the phone only charging on the USB and not on the wall power even on a properly functioning wall point?

    I'm having problems with my Galaxy s3. It will only charge with a certain charger and i have to toy around with it in order for it to charge, it charges extremely slow and dies extremely quick. My husband went and bought a new charger, and the charger doesn't even charge my phone no matter what even i try playing around with the cord.
    WHAT COULD MY PROBLEM BE? My phone is a necessity and I cant keep having it plugged in 24/7 for it to die in an hour and I can't even touch it while its charging because the charger has to be a certain way.

    my phone could connect with any usb cable except one. and that one usb cable could also connect to any device except the phone; which is very weird. after reading this, I came to a conclusion that either (or even both) inner wirings/metal parts of it could be off due to wear and tear causing them not to connect properly. i somehow able to connect them if i insert it at a slight angle. i find this article very informative although i do not dare to mess with the inner parts to fix it.
