Because a pager is just a radio receiver and not a radio transmitter. A cell phone or a cordless phone are both a receiver and a transmitter. A receiver uses much less battery power than a transmitter does. And because a pager's disposable alkaline battery holds more power than a cell phone or cordless phone's rechargeable battery.
The first pager was developed by an engineer named Al Gross in 1949. He is credited with inventing the prototype for the modern pager.
Pagers receive messages through radio frequencies. When a message is sent to a pager, it is picked up by a base station or a satellite, which then transmits the message over the airwaves to the specific pager using its unique frequency or code. The pager then displays the message on its screen for the user to read.
The Dell Latitude was released in 2003. The battery life for this laptop is between four and five hours. However, over time, the battery life for any laptop will shorten as the battery and the product age. A Latitude in use for the past decade would have a much shorter battery life than four hours.
It is generally better to have a low CPU usage, as this indicates that your computer is not overly taxed and can better handle tasks efficiently. A high CPU usage can lead to slow performance, overheating, and reduced battery life.
The key factors to consider in a lithium battery life cycle analysis include the environmental impact of battery production, energy consumption during use, potential for recycling or disposal, and overall lifespan of the battery.

According to research, the Energizer brand LED light provides a long battery life. It is also better to use an LED as it does not use as much battery life.
The battery life for a camera like this would be about five hours. You could purchase rechargeable batteries to make the cost a bit better though. This is a good amount of battery life for a camera.
