Why do older phone batteries last longer than current smartphones?

- 

There are several reasons why older phone batteries might last longer:

1. Battery technology

Older phones often used simpler battery technologies, such as Nickel-Cadmium (NiCd) or Nickel-Metal Hydride (NiMH), which were more durable and less prone to degradation. Modern smartphones use Lithium-Ion (Li-ion) batteries, which are more energy-dense but also more sensitive to charge cycles.

2. Power consumption

Older phones had fewer power-hungry features, such as:

• Lower-resolution displays;

• Less powerful processors;

• Fewer sensors and connectivity options.
