How to Know When Your iPhone Is Finished Chargingby Avery Martin
The release of Apple's iPhone 5 debuted a new charger that works differently than the chargers provided with iPhone 4 and previous models. The new Lightning to USB Cable provides syncing and charging with the added benefit of a much faster transmission rate. Lightning cables may also be plugged in to the iPhone quickly since the end that attaches to your phone is reversible. Completely charging your iPhone ensures that you get the most possible battery life out of each use.
Connect your iPhone to the small end of the Lightning to USB Cable. Then, connect the USB portion to an available USB port on your computer or the Apple USB power adapter plugged into a wall outlet.
Check the main screen on your iPhone by clicking the Home button to view the current charge status. A picture of a battery colored with red indicates your battery is near empty. The level of green that appears in the battery indicates how close to a full charge you have.
Check the status icon in the menu bar and note the percentage attached to the battery icon. The percentage tells you how much charge you currently have. When it reaches 100 percent, the iPhone has completely charged.
- Increase battery life by disabling unneeded functions. You can turn off Wi-Fi and the cellular data connection, disable Bluetooth when not needed, reduce the brightness, turn off location services or set your auto-lock preferences to increase battery life. Each of these options provides useful features, but if battery life is your priority, you can change these settings as you need them. Locate all of these settings by tapping the "Settings" app. Wi-Fi and Bluetooth settings are located in the main Settings window; other settings are located under the General option.
- To show the actual percentage of battery life left, tap "Settings," "General" and "Usage." Scroll down and tap the "Battery Percentage" option to "On" in the Battery Usage section.
- Apple's iPhones use lithium-ion batteries that revert to a trickle-charge at the end of the charging process. This prevents your iPhone from overcharging and means you can leave it plugged in for extended periods of time.
- Speed up the charging process when connected to a computer by plugging your computer into a power source when using a laptop and disconnecting any external devices.
- The Apple USB power adapter makes it possible to connect your iPhone into a wall outlet. The wall outlet charges your iPhone more quickly and can help recover your iPhone if it enters a deep discharge state and won't turn on.
