Paying attention to just a few common sense pointers will pay off with a longer battery lifespan and battery life for your iPhone. The most important thing is to keep your iPhone out of the sun or a hot car (even the glove box). Heat will degrade your battery’s performance the most.

Some Terms You Need to Understand
“Battery life” means the time your iPhone will run before it must be recharged (also called “talk time” or “playtime”). “Battery lifespan” means the total amount of time your battery will last before it must be replaced.

iPhone Temperate Zone. Your iPhone works best from 32° to 95° F. You should store it in environments of -4° to 113° F. That’s 0° to 35° C and -20° to 45° C for the metrically inclined. Keeping your iPhone as near room temperature as possible (72° F or 22° C) is ideal.

Update To The Latest Software
Always make sure iPhone has the latest software from Apple, as engineers may find new ways to optimize battery performance. Using iTunes 7.3 or later, you can update your iPhone with the latest software. Connect your iPhone to your computer, then select iPhone in the Source pane. In the Summary tab, you can click “Check for Update” to see if there’s a new version of the iPhone software available. Click Update to install the latest version.

Use The iPhone Regularly
For proper maintenance of a lithium-based battery, it’s important to keep the electrons in it moving occasionally. Be sure to go through at least one charge cycle per month.

Extend Your Battery Life
If you want to extend the battery life of your iPhone for any given charge cycle, you may conserve power by following these tips.

Lock Your iPhone
It may seem obvious, but you should lock your iPhone when you aren’t using it. You will still be able to receive calls and text messages while it is locked, but nothing happens if you touch the screen. To lock iPhone, press the Sleep/Wake button.

Optimize Your Settings
A few features use your iPhone battery more quickly. If you adjust these feature settings, your battery life will be improved.

  • Wi-Fi – Wi-Fi consumes power even if you are not using its features to connect to a network. You can turn it off to save power. Go to Settings > General > Network > Wi-Fi.
  • Bluetooth –  Likewise, you can turn off Bluetooth to maximize battery life, as it also consumes power when not in use. Go to Settings > General > Bluetooth.
  • Auto-Brightness – Turning on Auto-Brightness allows the brightness to adjust based on current lighting conditions. Go to Settings > Brightness.
  • Equalizer – Adding EQs to playback uses more of your processor, since they aren’t encoded in the song. Turn EQ off if you don’t use it. If, however, you’ve added EQ to tracks in iTunes, you’ll need to set EQ to “flat” in order to have the effect of “off,” because iPhone keeps your iTunes settings intact. Go to Settings > iPod > EQ.
