Smartphone/Mobile Phone battery takes forever to charge

Question by Guest | 2013-09-20 at 21:35

Since some days, something does not seem to be in order with my phone. Previously, it has taken almost exactly 2 hours to fully charge the battery of my phone.

However, at the moment, this time interval gets more and more out of control. Most recently, it has taken about 8 hours until the battery was fully charged to 100 percent. Is my battery damaged or can I still adjust it?

Of course, the behavior you are describing may have different reasons. In the worst case, your battery, your charger, the cable or the phone is broken and you have to buy a new one. Of course, you should first try another charging cable, sometimes this works wonders.

But before, you should try the following:

  1. Completely discharge the battery.
  2. Take the battery out of the device for about 20 minutes.
  3. Put in the battery again and charge the phone completely.
  4. Also at the next charging time, the battery should be completely emptied before it sees the charger again.
  5. The complete drain and fully recharge should be repeated about 2-3 times but removing the battery should only be done at the first time.

This procedure has the following background: the battery has something like a "memory" that remembers the time when it is empty, when it is full and some other parameters. With putting out the empty battery, you are erasing this memory and after that, the phone and the battery can calibrate or gauge again.

Sometimes, the memory of the battery gets confused when the phone often is not fully discharged and also not fully charged.

Unbelievable, but your tip has really helped! I must admit that lately, I have often connected my smartphone only for a short time with the charger.

This must surely have affected the memory of the battery.

Another reason for the eternal charging time may be that the contacts at the plug, the socket or the connector of the charger or the phone are dirty or a little bit oxidized. This can also result in less energy that can flow making the charging process taking longer. In this case, a new cable or cleaning can help.

Incidentally, also charging at the USB port of a computer is taking longer than connecting the phone to the wall socket. Here, someone has also wondered about that fact.
