NOTE:
If the battery level decreases fast when no application is consuming
power, there may be a battery failure, and you may need to change
the battery.
If you use the phone for a long time, such as when you are on
the call, surfing the Internet, gaming, watching videos, or
using navigation, your phone may generate heat. The heat is
caused by power consumption generated when the CPU is
operating fast. It is a normal phenomenon instead of a phone
failure.
It is also normal when the phone heats up during the charging
process.
A smartphone has advanced computer-like functions, such as
network surfing and various applications. These functions
consume more power than a feature phone. A smartphone
consumes power fast when it is connected to the Internet.
Besides, the signal strength may also affect battery usage. In
a weak-signal environment, the phone consumes extra power
to search signal. To summarize, a smartphone’s battery life
depends on many factors, such as signal strength, network
and game applications, and navigation.
Personal Identification Number (PIN):
The PIN is used to prevent unauthorized usage of your SIM
card. It is made up of four to eight numbers and is usually
provided with the SIM card. It is recommended to change the
original PIN before using the phone. The phone’s user guide
provides the procedure for changing the PIN.
The PIN2 is also made up of four to eight numbers and is
provided with some SIM cards. You need to enter the PIN2
when using some services.
If you enter the wrong PIN three times successively, you
need to enter the corresponding PUK to unlock the PIN.
PIN Unlock Key (PUK)
PUK is made up of 8 numbers. When the PIN is locked, you
need to enter the PUK to set a new PIN.
To change the locked PIN2, you need to enter the PUK2.
The PUK is provided by your network operator.
