Why do people disagree about charging to 100% versus 80%?

The two sides weigh different things. One values having every bit of battery available today, the other values keeping the phone healthy for years. Built-in charging protection and personal usage patterns also make the effects feel different from person to person.

What are the benefits of charging to 100%?

You get the longest possible runtime, which is handy on long days, trips, or whenever an outlet is hard to find. It also removes the need to watch the percentage or remember to unplug, so it is simple to stick with.

Why do some people stop charging around 80%?

They believe a battery sitting at full charge for long stretches wears down faster, so they prefer a gentler routine. Many phones now offer a charge limit setting, which makes this habit easy to automate without much effort.

Whether to top your phone up to 100% or pull the plug around 80% is one of those small habits people defend surprisingly hard. The full-charge crowd wants maximum runtime for the day ahead, while the 80% crowd believes that keeping a battery away from its extremes helps it age more gracefully. Phones differ in how they manage charging, and everyone's routine is different, so neither camp can claim a clear win.
