Bluetooth has been around for a long time now and is most commonly used for wireless headsets on mobile phones which is what it’s used for primarily on iPhone too.
It does however have around 25 more uses on phones but these aren’t enabled or indeed possible on iPhone’s Bluetooth.
With this in mind, do you really need Bluetooth enabled?
Bluetooth is notorious for zapping your battery and whilst not currently a security concern on the iPhone (due to the lack of data functionality) it may in the future be possible for people to access your iPhone if left enabled at all times.
This appears as a part of my iPhone Battery Saving Tips & Tricks article.
This has been carried out and tested on an iPhone 3GS running iOS4.
Disable Bluetooth on iPhone OS 3 & iOS4
- Tap Settings
- Tap General
- Tap Bluetooth
- Switch off your iPhone’s Bluetooth by toggling the switch to OFF.
- Press the Home key to return to the springboard.
