When compared with older models, the rechargeable batteries in today’s iPhones are certainly impressive, however, they are hardly everlasting.
Yet it turns out most people are probably charging their iPhones incorrectly.
Don’t charge your iPhone all the way
Studies have shown that charging your iPhone’s lithium-ion battery to 100 percent actually damages it.
This in turn reduces its lifespan, giving you fewer charges overall.
While the data varies on which percentage you should be aiming for, the general consensus, in this case, seems to be the lower the better.
Many seem to think that 80 percent is the number to strive for when charging your phone as going any higher requires its battery to use a higher voltage.
It is when phones utilize this high voltage that the battery sustains the most damage.
