How do I update my phone software?

We periodically release Windows Phone software updates to add new features you've asked for and to maximize your phone's performance. 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:

  • Make sure your phone is well-charged, so you don't lose power during the update.
  • 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.
  • Make sure you have enough storage space on your phone for the update. To check how much you have available, in the App list, go to Settings Settings icon > Phone storage. For more info about how to move things off your phone 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 Settings icon > Phone update.

  2. Tap the Automatically download updates if my data settings allow it Check box icon 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 track data usage. (Not all mobile operators offer Data Sense.)

How to check for updates manually

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

  2. Tap Check for updates.

  3. Make some room on your phone for the update. If necessary, remove a few unwanted apps or other large items.

Note

Windows Phone will let you know when new updates are available. If you check manually for an expected update and your phone appears to be up to date, it may be that it isn't available yet for your specific phone, mobile operator, or market.

How to install an update

  1. If you aren't set up to automatically download updates, tap Download when prompted after checking for updates or receiving an update notification.

  2. Do one of the following:

    • Tap Install, tap Show details, and then tap Install again. Your phone will restart, and then install the update.
    • Tap Postpone if you want to go back to Settings Settings icon > Phone update later to install the update.

    Note

    It usually takes 5 to 10 minutes to install an update, but it could take longer.

  3. After your phone restarts, wait for it to migrate your settings, and then tap Done to finish the update.
