I know that I probably shouldn't let the battery run so low on my Kindle Fire, but occasionally I have let it dip below 5%. Once this happens, the device no longer let's me trickle charge, and it powers itself down, even while plugged in.

Is there a way to override this setting? Sometimes I want to finish something up before letting it rest and charge up completely. To what extent does it damage the battery to run it so low?

    I believe the Kindle Fie is designed to shutdown when the battery charge is low to protect the battery cells from being damaged (Lithium Ion batteries self-discharge). Not a good idea to let them run too low (often).

Unfortunately this is not possible. The exact explanation for this actually comes from Android. Buried deep within the Android source code is this little gem:


private void shutdownIfNoPowerLocked() {
    if (mBatteryLevel == 0 && !isPoweredLocked(BatteryManager.BATTERY_PLUGGED_ANY)) {

This basically forces the system to shutdown if the battery level reaches 0%. The isPoweredLocked function determines whether any of the following are true:

  • The battery status is unknown
  • The device is connected to AC
  • The device is connected via a USB cable
  • The device is within range of a wireless charger

It should also be noted (as Jason mentioned in his comment) that lithium-ion batteries typically power off when they reach a predetermined low voltage to prevent further discharge and consequent damage.

  • No problem - I ran into a similar problem when the battery gauge on one of my Android phone went berserk and it wouldn't stay powered on even with a full battery. Commented Jan 12, 2014 at 1:27
