In the not-too-distant past, we were able to go about our days without a 24/7 lifeline to Facebook, Pokemon Go, or the wikipedia page for Bloop. Yet, these days, most are all too familiar with the anxiety that comes from seeing your iPhone’s battery hit the red. And the worst part? We could have been avoiding that anxiety all along by taking a few simple precautions.

With these simple tips, your phone’s battery will live longer and you won’t have to worry. Because sometimes, knowledge really is power.

It turns out that, according to Battery University, a site run by manufacturer Cadex, our cellphone’s lithium-ion batteries are susceptible to stress (much like we are when our phones die). So they recommend a few tips to keep your phone’s energy pumping!

For starters, don’t keep your phone plugged in when it’s fully charged.

It can be tempting to leave it charging over night, but this creates “trickle charges.” That means that the battery stays in high-stress, high-tension mode. Instead, unplug the battery, which “is like relaxing the muscles after strenuous exercise.”

Actually, don’t even bother charging your phone to 100% at all.

Per 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.”

It’s better to plug your phone in periodically throughout the day, in small doses.


Using occasional “top-ups,” allows your battery to stay fresh without the strain of a full 0-to-100 charging session. This doesn’t necessarily mean charging every 5 minutes, but it’s good to do so periodically throughout the day.

Make sure it stays cool.


Apple and battery manufacturers both recommend that you keep your phone out of the heat, due to the heat affecting your battery. This includes taking your phone out of your case if you notice that it gets hot while you’re charging it.

Oops, I always plug my phone in over night! I’m sorry, iPhone! I promise to treat you better from now on.
