Windows Phone's Software Update details.

      Maximum Phone's speed and others performance depend on latest or upgrade phone's software. In a windows phone, when a software update is available for you to download, we'll notify you so you can download it

directly to your phone over a Wi-Fi or cellular data connection. To see what features or improvements have been added in the latest update, see Windows Phone 8 update history.

Before you download and install an update:

• Charge your phone. We won't perform the update unless your phone has sufficient power.
• If you're worried about cellular data charges, use Wi-Fi and manually download the update. See How can I minimize my data usage? to learn more.
• You'll need to have enough storage space on your phone so we can perform the update. If you try to update and you don't have enough free space, we'll prompt you to go to Storage Sense to make room. To check how much space you have available, in the App list, go to Storage Sense (in Windows Phone 8, go to Settings > Phone storage). For more info about how to make more room, see Make room on my phone to update it.

How to download updates automatically

1. In the App list, tap Settings > Phone update.
2. Select the Automatically download updates if my data settings allow it check box.

   Note

   Updates won't download if data settings on your phone prevent it. For example, both Data Sense and Battery Saver can limit how your phone uses data. To learn more, see Use Data Sense to manage data usage and Battery: making it last. (Not all mobile operators offer Data Sense.)

1. In the App list, tap Settings > Phone update.
