Why is my phone taking so long to charge?

Question

I’ve only had my phone for a couple months and it is already not taking a charge like it should. I can charge it for 8 hours and still only increase the battery by 20%. Even when I finally do get it charged, it loses charge way too fast. If I try to switch mobile data, it drains the battery completely within an hour. Why is my phone taking so long to charge?

With my last phone, I did the whole “kill the battery before charging it” and it worked. Not with this phone. My phone died about 9 PM last night. I charged it all night and still only have a 34% charge on my battery.

Is this just a fluke that newer “smart” phones have? Am I doing something wrong? Has anyone else had this kind of issue with their smartphones? I really don’t want to have to go to Samsung for help if I can figure it out without doing so.

Answer 1

Why is my phone taking so long to charge? The answer is easy: Try only charging your phone while it is off. This works best for me with my Kyocera Hydro Icon (not Samsung, but a smartphone none-the-less). I make sure all my apps are shut down, WiFi and Bluetooth are shut down, then turn my phone off to charge. This makes a world of difference. Also, if you are in an area that your phone is constantly “searching for service” put the phone in airplane mode. My phone’s battery dies way more quickly when it is constantly searching for service. If this doesn’t work, you may just have to break down and contact Samsung.

Answer 2

There are several reasons why a smartphone doesn’t take a charge properly. Here are my suggestions:

• Check your charger: If you are using a cheap charger (not the original that came with the phone), your phone may not be getting the correct charge. Always use the original charger if you are able to. If something happened to your original charger and you have to replace it, make sure to buy another one that is good quality and has the same amps. This is very important. If the amp is smaller than the original (which is made to work correctly with your phone), it will take your phone longer to charge; and could, in fact, kill your battery life completely.
• Check your USB ports and cable: Make sure there is no dust or other particles within either end of the USB cable and the ports where they plug in (make sure to check all areas:  charging port, phone input, and BOTH ends of the cable). If they are dirty, clean them out. If the particles are inside, get an electric cleaner than forces air (like a keyboard cleaner) to get the dust and other particles out. If this isn’t the problem, it could simply be your cable. It could be faulty. Try replacing your cable.
• Check your battery: Although you have a new phone, the constant recharging you’ve been doing (especially if it is with a charger not compatible with your phone), your battery may have suffered. There is usually a battery life indicator on the battery. Check your manual to see. Also, try not to overcharge your battery. This is hard to do with most phones having an overcharge protection, but it is always possible. Worst case scenario:  you may have to break down and replace your battery.
• You could be the problem: Are you constantly using your phone while it’s charging? This will drain the battery (and sometimes make the battery and phone very hot to the touch) quicker than anything else. I know we all feel we need our phones constantly but the worst thing you could do for your battery’s life is use it while it is plugged in!

Wish these tips may help you. If the above methods fail to solve the problem, I think you have to ask help from Samsung.
