Battery Care
Use Battery Care to increase the lifespan of your battery. This feature detects your
charging patterns and estimates the start and end time of your regular charging
period. The charging rate is controlled so that your battery reaches 100% just
before you disconnect the charger.
Battery Care will not control the charging rate until it detects a regular charging cycle of at
least 4 hours over a period of several days.
To enable or disable Battery Care
1 Find and tap Settings > Battery > Battery Care.
2 Tap the slider to enable or disable Battery Care.
Learned patterns of the regular charging cycle are saved by Battery Care. Even if the
function has been disabled, it adopts to the learned patterns after enabling the function
again.
Updating your device
You should update the software on your device to get the latest functionality,
enhancements and bug fixes in order to ensure optimal performance. When a
software update is available, appears in the status bar. You can also check for
new updates manually, or schedule an update.
The easiest way to install a software update is to do it wirelessly from your device.
However, some updates are not available for wireless download. You then need to
use the Xperia Companion software on a PC or Mac computer to update your
device.
Before updating your device, consider the following:
• Ensure you have sucient storage capacity before attempting to update.
• If you are using a device with multiple users, you must log in as the owner, that is,
the primary user, to update the device.
• System and application updates can present the features on your device in another
way than described in this User guide. The Android version might not be aected
after an update.

the owner.

Updating your device wirelessly
