iPhone Battery Draining Fast: Troubleshooting Tips
Now that you know what a standard iPhone battery life is, you'll know if yours is draining unusually fast. If you're dropping from a full charge to near death in a short amount of time, it's time to try to fix the problem. There may be a few things that could save you from needing to buy a new battery.
Things That May Cause iPhone Battery to Drain Faster
High Usage - Using your phone a lot? If so, this could be the cause of a fast draining battery. If you'll be using the Internet and/or talking on the phone a lot, your battery will lose juice much faster than if you were listening to music or leaving your phone on standby. Try charging your phone more often when using it frequently.
Settings - Your settings may not be optimized for maximum battery life. Some settings, such as having Wi-Fi turned on, can be very draining to the battery. Make sure to turn off all data features that you aren't using to avoid unnecessary drain.
Multitasking - You may have too many apps running in the background causing a strain on your battery. Close out all applications that you are not using. Double tap the home screen to show the multitasking menu to close unused apps.
Operating System Malfunction - If you've tried limiting usage, optimizing your settings and limiting multitasking and still find yourself having trouble with the battery draining too fast, there could be a problem with your operating system. You'll want to restore the iPhone to try to clear up the problem.
Battery - If all those things don't help, then I have some bad news for you. Your battery is the culprit after-all and it needs to be replaced. Apple's warranty covers battery replacement for 1 year after your phone is purchased or 2 years if you purchased Apple Care for your device. Past those time limits? You'll probably have to shell out $79 plus shipping to have Apple replace your battery. Consult your local Apple store or wireless carrier for more information.
