Predicts your power levels
The Xperia XZ1 estimates how long your battery will last, based on how you normally use your phone.
Warns you early
If it thinks you’re going to run out of power later in the day, it prompts you to activate STAMINA mode.
Makes your battery last
STAMINA mode cuts energy consumption so your battery lasts all day.
Smarter charging cycles
Leaving a fully-charged battery plugged in can damage it. Battery Care charges your phone to 90%, waits, then charges to 100% just before your wake-up time.
