You've been charging your smartphone wrong

Yes, we know. Our smartphone batteries are bad because they barely last a day.
But it's partially our fault because we've been charging them wrong this whole
time.
Many of us have an ingrained notion that charging our smartphones in small
bursts will cause long-term damage to their batteries, and that it's better to
charge them when they're close to dead.
But we couldn't be more wrong.
If fact, a site from battery company Cadex called Battery University details
how the lithium-ion batteries in our smartphones are sensitive to their own
versions of "stress." And, like for humans, extended stress could be damaging
your smartphone battery's long-term lifespan.
If you want to keep your smartphone battery in top condition and go about your
day without worrying about battery life, you need to change a few things.
Don't keep it plugged in when it's fully charged
According to Battery University, leaving your phone plugged in when it's fully
charged, like you might overnight, is bad for the battery in the long run.
Once your smartphone has reached 100% charge, it gets "trickle charges" to keep
it at 100% while plugged in. It keeps the battery in a high-stress,
high-tension state, which wears down the chemistry within.
Battery University goes into a bunch of scientific detail explaining why, but
it also sums it nicely: "When fully charged, remove the battery" from its
charging device. "This is like relaxing the muscles after strenuous exercise."
You too would be pretty miserable if you worked out nonstop for hours and hours.

In fact, try not to charge it to 100%
At least when you don't have to.
According to Battery University, "Li-ion does not need to be fully charged, nor
is it desirable to do so. In fact, it is better not to fully charge, because a
high voltage stresses the battery" and wears it away in the long run.
That might seem counterintuitive if you're trying to keep your smartphone
charged all day, but just plug it in whenever you can during the day, and
you'll be fine.
Don't shoot your smartphone batteries, either.24M
Plug in your phone whenever you can
It turns out that the batteries in our smartphones are much happier if you
charge them occasionally throughout the day instead of plugging them in for a
big charging session when they're empty.
Charging your phone when it loses 10% of its charge would be the best-case
scenario, according to Battery University. Obviously, that's not practical for
most people, so just plug in your smartphone whenever you can. It's fine to
plug and unplug it multiple times a day.
Not only does this keep your smartphone's battery performing optimally for
longer, but it also keeps it topped up throughout the day.
Plus, periodic top-ups also let you use features you might not normally use
because they hog your battery life, like location-based features that use your
smartphone's GPS antenna.

Keep it cool
Smartphone batteries are so sensitive to heat that Apple itself suggests you
remove certain cases that insulate heat from your iPhone when you charge it.
"If you notice that your device gets hot when you charge it, take it out of its
case first." If you're out in the hot sun, keep your phone covered. It'll
protect your battery's health.
