10 hot and useful tips to maximize iPhone's battery life

posted on: Monday 7th July 2008

Apple Inc. claims that iPhone has 8 hours talk time, 250 hours of standby, 6 hours of Internet, 7 hours of video playback and 24 hours of audio playback!! These are very impressive numbers, except that claims has lots of strings attached which no one actually reads it.

Although, you may not get even close to these numbers, but I will attempt to provide all tweaks and settings to get as close as possible. I have collected most of these tips from Apple's fine prints and some from support page of an iPod. Don't worry, I am not going to ask you to turn of Wi-Fi or other features that would simply cripple your iPhone.

1. Brightness setting: this alone can do the trick of getting most out your iPhone's (or any device for that matter) battery life. Even though iPhone has bright and gorgeous screen, you may want to turn it down to get that screen playable little longer!
   How-to: "Settings" -> "Brightness" -> slide it to about one seventh
2. Auto brightness: iPhone has built-in sensor that checks the lighting condition where ever you are and adjust the brightness accordingly. This is sweet feature, but the sensor eats up battery life.
   How-to: "Settings" -> "Brightness" -> turn the "Auto-Brightness" switch "OFF"
3. Auto-Lock: turn that display off as frequently as possible. Make sure it is set to 1 Minute
   How-to: "Settings" -> "General" -> "Auto-Lock" -> "1 Minute"
4. Auto detect Wi-Fi: iPhone has feature to
   How-to: "Settings" -> "Wi-Fi" -> "Ask to Join Networks" -> turn "OFF"
5. Email Check frequency: this may not be suitable for lots of business or frequent email users, but it does save battery life. You can set iPhone to check email every 15, 30, 60 minutes or do manual check. Of course, ideal setting for saving battery would be "Manual", but you can also set to "Every hour"
   How-to: "Settings" -> "Mail" -> "Auto-Check" -> select "Manual" or "Every hour"
6. Turn of some sounds: iPhone makes noise for about everything you do on it. You can turn off some of these sound effects such as keyboard click noise and Lock Sound noise. These two are really unnecessary for the most part.
   How-to: "Settings" -> "Sounds" -> "Lock Sounds" turn "OFF" and "Keyboard Clicks" turn OFF
7. Turn of that Equalizer: yes, according to Apple, turning of Equalizer will save little battery time!
   How-to: "Settings" -> "iPod" -> "EQ" -> "Off"
8. Turn of Sound Check: iPhone provides Sound Check feature to adjust music volume to keep consistent range for all songs. Most of the time it does not work (at least for my songs). So you can turn it off to save some juice.
   How-to: "Settings" -> "iPod -> "Sound Check" turn "OFF"
9. Audio encoding: compress size of your music file for better cache purpose and encode using MP3 or AAC encoding. AIFF and some other formats are not good and eats up CPU cycles
   
10. Room Temperature: Keep iPhone in room temperature and do not charge your iPhone while it is in carrying case or cover. This keeps battery in ideal temperature even when charging.
    

Hope these tricks help you get more life out of your iPhone's battery. Just as an additional note, Apple has also announced iPhone's battery replacement program for $79.99 + shipping. read it here: http://www.apple.com/support/iphone/service/battery/
