How much battery life you consume may vary, depending on how you use your BlackBerry Z10 smartphone. To help your battery last longer, try any of the following tips:
Check for BlackBerry 10 OS Updates
Whenever a new BlackBerry 10 OS update is released, make sure to install it on your smartphone so that you can take advantage of any available optimizations which can help improve your battery life. Typically, you’ll receive a notification of a new update, but to check for updates manually, open Settings, tap Software Updates followed by Check for Updates.
Tip: To access your BlackBerry Z10 Settings, swipe down from top of the screen while viewing your Home screen and tap Settings.
The radios on your smartphone are designed with efficiency in mind, so turning off Wi-Fi, Bluetooth or NFC as well as changing your cellular connection to use a different network technology may not improve battery life. We recommend using Wi-Fi whenever possible because it offers substantial power savings, so make sure you are actively adding Wi-Fi networks and hotspots to your smartphone as you come across them.

The BlackBerry Z10 smartphone is designed make efficient use of the battery; however, you should still follow best practices to maximize your battery’s lifespan. Always use an official BlackBerry charger, charge for an extended period of time when possible, avoid charging in small increments (i.e. less than 15 minutes), and do not your leave smartphone in direct sunlight (i.e. your vehicle’s dashboard) or in extremely cold temperatures.
- Whenever possible, it is recommended that customers use Active Sync or IMAP over POP when setting up a new account because they are more efficient protocols for a mobile device. If you need assistance setting up a new account, review the BlackBerry Z10 User Guide or contact your account provider for more information.
- If you have set up multiple accounts that support email, contacts, and calendar synchronization, enable synchronization for accounts that you only plan on using; this will ensure that any activity that occurs is necessary. To review account synchronization settings, tap Accounts within Settings followed by tapping the account you want to customize and/or delete.
- Remove any accounts that you are no longer actively using to reduce overhead and to prevent them from using the battery to stay updated.
If you receive many notifications throughout the day, make sure you review and customize your notification profiles. For example, if your smartphone is set to vibrate, this will use more battery life than having the LED light up as more notifications arrive. If you receive a lot of notifications overnight as well, swipe down from the top of the screen after locking your smartphone to enable Bedside Mode, which will turn off all notifications overnight.
A significant way to reduce battery usage is to decrease the brightness of the BlackBerry Z10 display. Within Settings, tap Display and move the Brightness slider to a reduced setting that you find comfortable.
To prevent accidental taps and presses that can turn on your screen (and decrease battery life), lock the screen by pressing the Power/Lock key on the top of your smartphone.

This setting controls how long your smartphone will wait before turning off the screen after being left idle. The less time that the screen is on, the more battery is conserved. To adjust this value, go to Settings, tap Display and change the Screen Lock Timeout.
