According to Apple, iPhone batteries are designed to sustain 80% of their capacity even after 500 charging cycles (charging and discharging). However, if you have a slightly older iPhone, replacing the battery would not only improve the battery backup but also improve the performance.

For some people, when the battery gets down and hit to 1% or 5%, the iPhone slows down and annoy users like anything.

Batteries are consumable, so as you use them, battery health will decline, based on the number of full charge cycles.
