Make Your iPhone Battery Last Longer


Extend the battery life on your iPhone by developing a few good habits. Replacing the battery in your iPhone can get pretty expensive, so make it last longer with this advice.

If you use a carrying case for your iPhone, charging the phone while it's in that case may generate more heat than is healthy for your phone. Overheating is bad for both battery capacity and battery life, so if your iPhone gets a little toasty when you charge it in its case, take it out of the case before you charge it.


Bluetooth consumes power even when it's not being used. If you're not using a Bluetooth device (such as a headset or car kit), make sure Bluetooth is turned off. To do so, tap Settings on the Home screen, tap General, tap Bluetooth, and then tap the On/Off switch if necessary to turn off Bluetooth.
Wi-Fi consumes power even when you're not using it, so turn it off when not in use. Tap Settings on the Home screen, then tap General, Network, Wi-Fi, and then tap the On/Off switch if necessary to turn off Wi-Fi.
Activating Auto-Brightness allows the screen brightness to adjust based on current lighting conditions. This can be easier on your battery than cranking it up and leaving it set to a bright setting. To activate this feature, tap Settings on the Home screen, tap Brightness, and then tap its On/Off switch if necessary to turn it on.
Turning on EQ when you listen to music can make it sound better, but it also uses more processing power. Turning off EQ will help your battery last longer.
If you've added EQ to tracks in iTunes via the Track Info window and you want to retain the EQ from iTunes, set the EQ on your iPhone to flat. Since you're not turning off EQ, your battery life will be slightly worse. But your songs will sound just the way you expect them to sound. Either way, to alter your EQ settings, tap Settings on the Home screen, tap iPod, and then tap EQ.
According to Apple, a properly maintained iPhone battery will retain up to 80 percent of its original capacity after 400 full charge and discharge cycles. But you can replace the battery at any time if it no longer holds sufficient charge to meet your needs
