How To Tell If An IPhone's Battery Is Dead,

The iPhone displays the charge amount left in the battery on the top-right corner of the screen. When your battery is very low, charge it to prevent it from going completely dead. Once your iPhone battery is completely dead, it is difficult to tell if your problem is simply a dead battery or something more serious. You'll need to plug your iPhone into an outlet or your computer and begin the charging process to know if your problem is a dead battery. Plug your iPhone into an outlet using the Dock Connector to USB cable and USB power adapter, or to your computer using the Dock Connector to USB cable. Press the "Home" button at the bottom of your iPhone to see the battery status if it does not automatically pop up. If the power is very low, you will see an image of an empty battery with a small red bar to the left. A lightening bolt will appear under the battery image to alert you that you need to wait a few moments to use your phone while it gathers a charge. Wait a few minutes if no image appears when you press the "Home" button the first time. If the battery is completely dead, you will need to wait a few minutes before the iPhone has enough power to display the low battery warning.

Although these upgrades come with improvements to battery life, it’s advisable to calibrate iPhone battery to maintain the battery in a good working condition.

It’s recommended that you perform this action when you know that you won’t be using your phone at least for several hours. You wouldn’t want to do this when heading to the work, with 5% charge left!

If possible, leave the battery drained overnight. Don’t charge it until the morning. If this is inconvenient, you may skip this option.

You can calibrate iPhone screen but the calibration is limited to motion sensors and screen brightness. Proximity to a magnet can affect iPhone’s motion sensors. When this happens, you should use iPhone’s Compass app to re-calibrate all motion sensors, including accelerometer, gyro and magnetometer. Tap the Compass app on the iPhone screen. Follow the on-screen prompt to tilt the iPhone screen and roll the red all around the circle. Continue to tile the iPhone until a compass appears on the screen. Now, all the motion sensors are calibrated. Move the slider at the top of Display & Brightness screen from left to right until you reach your preferred level of brightness. Turning on auto-brightness in the Display & Brightness screen lets iPhone choose the brightness level that’s optimum as you move from one lit environment to a differently lit environment. When auto-brightness is off, the brightness level remains constant, irrespective of change in environment. Looks like there is no way to adjust the sensitivity of your iPhone screen i.e., you cannot calibrate the sensitivity. Hard reset the iPhone by holding the Home and Sleep buttons for 10 seconds. If your screen is still malfunctioning, contact Apple Support. So that’s it, folks! We hope you are now aware of methods to calibrate iPhone battery and screen.
