Droid Bionic: Monitor the Battery
The Droid Bionic displays the current battery status at the top of the screen, in the status area, next to the time. The icons used to display battery status are shown in this figure.
You can check the specific battery level by following these steps:
At the Home screen, press the Menu button.
Choose About Phone.
The top two items on the Status screen offer information about the battery:
Battery Status: This setting explains what’s going on with the battery. It might say Full when the battery is full, Discharging when the battery is in use, or Charging when the battery is being charged. Other text may be displayed as well, depending on how desperate the phone is for power.
Battery Level: This setting reveals a percentage value describing how much of the battery is charged. A value of 100 percent indicates a fully charged battery.
Heed those low-battery warnings! The phone sounds a notification whenever the battery power gets low. (See the orange Battery icon shown.) The phone sounds another notification when the battery level gets very low. (See the red Battery icon in the figure.)
When the battery is too low, the phone shuts itself off.
In addition to the status icons, the Droid Bionic notification light turns a scary shade of red when battery juice is dreadfully low.
The best way to deal with a low battery is to connect the phone to a power source: Either plug the phone into a wall socket or connect the phone to a computer by using a USB cable. The phone charges itself immediately; plus, you can use the phone while it’s charging.
The phone charges more efficiently when it’s plugged into a wall socket rather than a computer.
You don’t have to fully charge the phone to use it. If you have only 20 minutes to charge and the power level returns to only 70 percent, that’s great. Well, it’s not great, but it’s far better than a 20 percent battery level.
Battery percentage values are best-guess estimates. Just because you talked for two hours and the battery shows 50 percent doesn’t mean that you’re guaranteed two more hours of talking. Odds are good that you have much less than two hours. In fact, as the percentage value gets low, the battery appears to drain faster.
