Wi-Fi network name is case sensitive. Choose a unique name for your network and that isn’t shared by other nearby networks. If your SSID isn’t unique, Wi-Fi devices will have trouble identifying your network. This could cause network device to fail to automatically connect to your network, or to connect to other networks sharing the same SSID.

Battery lifespan is the amount of time your battery lasts until it needs to be replaced.

 

General Performance Tips & Solutions

 

  • Update your Apple device to the latest software updates & operating system:

    • Apple software updates often include advanced energy-saving technologies, so always make sure your device is running with the latest version of iOS, OS X, or watchOS.

     

  • Avoid extreme ambient temperatures: Your device is designed to perform well in a wide range of ambient temperatures, with 62° to 72° F (16° to 22° C) as the ideal comfort zone. Avoid exposing your device to ambient temperatures higher than 95° F (35° C), which can permanently damage battery capacity.

What is trust settings means to your iOS & OSX device

 
Background: When you connect your iPhone, iPad, or iPod touch to a computer first time an alert asks whether you want to trust this computer or not.

 
Relationships of Trusted Devices:

  1. Trusted computers can sync with your iOS device, create backups, and access your device’s photos, videos, contacts, and other content.
  2. These computers remain trusted until you change device privacy settings or erase your iOS device.
  3. If you choose not to trust a computer, you block its access to content on your device. You’ll see the trust alert every time that you connect your iOS device to that computer.
