IMEI number

provider can use your IMEI number to stop the device from accessing the network in
your country.

Make sure your device is turned off.
Detach the cover for the micro SIM card and memory card slot.
Using a fingernail, remove the two label trays (in the order shown in the
illustration) to view your IMEI number.
To view the IMEI number, you can also open the phone dialer on your device and enter *#06#.

Find and tap Settings > About phone > Status.
Scroll to IMEI to view the IMEI number.
Battery and power management
Your device has an embedded battery. You can keep track of your battery
consumption and see which applications are using the most power. You can also
view an estimate of how much time is left before your battery runs out. The estimated
battery time is based on your most recent usage pattern.
To make the battery last longer you can use one or more battery saving modes,
which include STAMINA mode, Low battery mode, Location-based Wi-Fi®, and
Queue background data mode. Each mode works in a different way and controls
several power consuming functions on your device.
To view which applications use the most battery power
From your Home screen, tap
Find and tap Settings > Power management > Battery usage.
To view the estimated battery time
From your Home screen, tap .
Find and tap Settings > Power management.
Improving battery time using STAMINA mode
STAMINA mode turns off functions that you don't need when your device isn't in use.
For example, STAMINA mode can pause your Wi-Fi® connection, data traffic and
several power consuming applications when your device is powered on but the
screen is inactive. So you save the battery but can still receive phone calls, texts and
multimedia messages as they come in. You can also exclude individual applications
from being paused by STAMINA mode. Once you activate the screen, all paused
functions are resumed.
