How long do smartphone batteries last?

Typically, a modern smartphone battery’s (Lithium-ion) has a lifespan of 2-3 years. That translates to about 300-500 charge cycles as rated by manufacturers. After that, the battery capacity will drop by roughly 20\%, leaving the battery with an effective 80\% of its normal capacity when it was new.

Is the 40-80\% rule for lithium-ion batteries true?

The 40-80\% rule is true. In truth, 20-80\% would also work. The upper and lower extremes stress out the lithium ions. Think of a battery like a balloon. If you completely fill a balloon every day, eventually it won’t be nearly as elastic and snappy.
