Apple iPhone 4 Battery Life

The iPhone is a very powerful smartphone for modern day technology and holds a very high capacity battery internally. The new iPhone 4 comes with an internal 3.7V 1420 mAh rechargeable lithium-ion battery, which powers the A4 processor, 512 MB of RAM, interactive touch screen and the rest of the iPhone 4’s hardware. Some rumors have been that the iPhone 4 can last anywhere between 4 hours to two full days off of one full charge. It all depends on how frequently you use your iPhone and how it is configured. Below are a few suggestions on how to optimize your iPhone settings.

  • Minimize use of location services – Applications such as Maps and will reduce your battery life each time it connects to the network. To disable location services, go to Settings > General > Location Services or use location services only when needed.
  • Turn off push notifications, fetch mail less frequently – Some applications have push notifications, such as Facebook and instant messaging apps. To disable push notifications, go to Settings > Notifications and set Notifications to Off.
  • Fetch new data less frequently – Some applications, such as your Mail will fetch data at a set interval. Fetching Mail at less frequent intervals will increase your iPhone battery life. To fetch new data manually, from the Home screen choose Settings > Mail, Contacts, Calendars > Fetch New Data and tap Manually. To decrease the Mail fetch interval, go to Settings > Mail, Contacts, Calendars > Fetch New Data and tap Hourly.
  • Turn off push mail - If you have a push mail account such as Yahoo! or Microsoft Exchange, turn off push when you don’t need it. Go to Settings > Mail, Contacts, Calendars > Fetch New Data and set Push to Off. 
  • Minimize use of third-party applications- Excessive use of gaming, chat, web browsing or applications with location services will drain the iPhone battery faster over time.
  • Turn off Wi-Fi – If you are not using Wi-Fi, just turn it off. Go to Settings > Wi-Fi and set Wi-Fi to Off. But if you have a Wi-Fi connection, use it because it is more efficient to use a Wi-Fi network versus a cellular data network.
  • Turn off Bluetooth – If you are not using Bluetooth, turn it off. Go to Settings > General > Bluetooth and set Bluetooth to Off.
  • Use Airplane Mode in low, or no-coverage areas – Simply enable airplane mode on your iPhone if you are not using it, in a meeting, have no coverage or just don’t want to be contacted all the time by those pesky cold callers. To turn on Airplane Mode, go to Settings and set Airplane Mode to On.
  • Adjust brightness – Turn down your screen brightness to conserve the iPhone battery power. Go to Settings > Brightness and drag the slider to the left to lower the default screen brightness.
  • Turn off EQ - Applying an equalizer setting to song playback on your iPhone can decrease battery life. To turn EQ off, go to Settings > iPod > EQ and tap Off.
  • Turn off 3G (GSM model only) – If you’re not browsing the internet or retrieving important email with large file sizes, then turn off your 3G network and just run off of the data network via EDGE or GPRS.
  • Close out running apps when you don’t need them – Don’t let apps run in the background as it take up processing speed and battery power to run them. Just simple double click the home button, and hold down on an app that is running in the background to remove it from the processing apps. Just don’t delete the app on accident.
  • Turn off Ping - To disable Ping, Go into Settings. > Tap on General, then Restrictions (right underneath Passcode Lock). > You will be prompted to enter a password and confirm it – make sure it’s a code you remember. > Enable restrictions and make sure all apps are “On,” but that Ping is the only one “Off”. This has been known the increase your iPhone’s battery life by several hours by just disabling Ping.
  • Keep good charging habits and care for your battery – Try to keep your iPhone in a room temperature environment when charging, idling or when in use. More specifically, keep it between 32 degrees and 95 degrees Fahrenheit.

According to Apple’s site, the iPhone 4 offers up to 7 hours of talk time on 3G, 14 hours of talk time on 2G (GSM model only), 6 hours of Internet use on 3G, 10 hours of Internet use on Wi-Fi, 10 hours of video playback, or 40 hours of audio playback on a full charge at original capacity. In addition, iPhone 4 features up to 300 hours of standby time. The iPhone battery life is designed to retain up to 80% of its original capacity at 400 full charge and discharge cycles. If your iPhone no longer holds sufficient charge, it may be time to upgrade your iPhone to the next faster and better model. The other alternative is purchasing an external iPhone 4 battery case that fits right over the iPhone 4 and double cell phone run time, while protecting it at the same time.
