One of our readers emailed us complaining about his Samsung Galaxy Note 2 that charges really slow. According to him when his device was still new, he would only spend around two hours for the phone to be fully-charged but just recently, the phone couldn’t finish charging even after 5 hours of being plugged in. He said he uses the original battery and charging unit and tried charging the phone while turned off but the problem persists.
This is not the first email we received about the issue. In fact, in previous emails, we were able to narrow down the problem so easily considering it started to manifest right after a firmware upgrade. But that is not the case in recent emails we received. There is a ton of possible reasons why this problem happens but the following are the things you could do in case you encounter this issue.
Use the charger, not the laptop / computer. Many are used to charging this phone using their laptops or computers. It charges but does take longer time to complete. Galaxy Note 2’s charging unit gives out 2A (2 amperes) current while the laptop usually gives out 0.5A and the desktop, 1A. Now you get the logic why charging your phone through these machines would take a little more time to complete.
Turn off phone while charging. One thing to speed up the charging process is to turn the phone until it’s full. If you haven’t done so, we urge you to try it; you’ll notice the battery becomes full much faster than when the phone is off. The downside, however, is that you won’t be able to receive text messages, incoming calls, or emails. But you can turn off some wireless connectivity when you’re not using them, at least, while you’re charging the phone.
Check the battery for possible quick draining issue. If the battery drains faster than usual, it is the reason why it takes so long to charge. We have published an article on how to troubleshoot this problem, we urge you to read it. (here’s the link)
Check the charger’s condition. If it’s not the battery or the device, then the problem could be in the charging unit. To check if it’s really the charger, you could try using it on another device to see if it charges well. Or, you could use a different charger for your device. Upon confirming that the problem is with the charger, buy a new one immediately and don’t use the old one as it might damage your phone or the battery in the long run.
