Ever since the Droid Incredible was first released, we have heard about bump charging, and many of us are left wondering what is it, and how does one accomplish such a thing? If you have ever taken your Incredible or Thunderbolt off the charger and noticed that nearly instantly you were down to 90 percent showing on your battery meter, and were puzzled.
Well, the device charges itself fully, but does not maintain that full charge, instead keeping around a 90- to 95-percent charge and showing full. So, people have begun bump charging their device to gain that last five to ten percent back. There are a few developers who are taking stabs at making custom kernels that will combat this, but that requires root, and flashing files, and all that jazz, so they have an alternative bump charging method, which goes as follows:
- Power up (if not already) and plug your device into a power source. As the battery is being charged, the notification LED shows a solid orange light.
- Wait until LED is solid green, indicating it is fully charged.
- Unplug, press and hold the power button, and select the option to power off.
- Once powered down reconnect power source.
- The LED will show a solid orange light again, indicating it is charging.
- Once it's green, unplug the device and use the power button to power up the device.
- Once Sense has loaded plug the phone back in again. You will notice that the LED is now orange again.
- Repeat steps 3-7 process until the light is green immediately upon plugging it back in (approximately 3-4 times).
So, if you want to ensure that you are starting your day out with truly 100% battery life, follow the simple steps above, but you will unfortunately have to do this each and every time the device needs to be charged.
