How to Maximize Battery Life on Your iPad, iPhone, or iPod Touch
After reading the article, all of the given pointers will help to get you the most out of your battery. However, there are a few that are more beneficial than others. I have summarized those for you below:
• Keep your iDevice Out of the Sun – This is probably the most important tip to remember in keeping your battery up to par.
• Reduce the Screen Brightness – You will need to adjust this to individual taste. I found that 50% is a reasonable setting and you will still benefit from extended battery life.
• Disable Bluetooth If You Don’t Need it- very good tip, since the iPad will continuously scan for Bluetooth sources. Turn this setting off, until you need to add a peripheral to gain that extra bit of battery life.
• (iPhone Only*) Disable Vibrate feature in Games – The vibration function uses quite a bit of juice, since the actual mechanism is a tiny motor that pulls battery power to operate. Turn this feature off to prolong battery life as well.
There are a few pointers the article mentions that may be more of an irritant to work around than to simply leave them at their default setting.
• Reduce or Eliminate Push Notifications – With this setting disabled, you will not be notified immediately of new mail until you click refresh, or wait on a predetermined amount of time.
• Reduce or Eliminate System Sounds – Very little impact on battery life, and if turned off, you lose the ability to have audible cues as to new email arrival, calendar events etc.
