Get the (iPhone) facts straight! Below I uncover four common Apple iPhone battery misconceptions.

Misconception 1: You should completely drain your iPhone’s battery before re-charging it.

Fact: Apple’s iPhone uses a Lithium-Ion battery, as opposed to the old type of battery, made of nickel cadmium. Lithium-Ion batteries are resilient, and they’re smart, so realistically you can charge them whenever you’d like. In order to extend the life of your battery, however, you’ll want to use the 40-80 rule whenever you can.

Misconception 2: You shouldn’t charge your battery overnight.

Fact: Your battery uses fast charging to quickly reach 80 percent of its capacity, then switches to slower trickle charging. This process not only lets you get out and about sooner, it also extends the lifespan of your battery. You shouldn’t leave your iPhone plugged in at all times, as it does affect your battery life a little bit, but it’s surely not going to ruin your battery.

Misconception 3: Disabling WiFi and Bluetooth will improve battery life.

Fact: This will help improve battery life a little, but these settings do not use as much battery as one may think. In the past, experts recommended turning off WiFi and Bluetooth when not in use, but these technologies are actually very energy efficient nowadays, so it is really not necessary.

Misconception 4: Closing out of open apps will improve battery life.

Fact: Even I was surprised by this one (and am completely guilty of believing this misconception). A huge myth among iPhone users, the process of closing and re-opening an app actually uses more battery than just leaving them running in the background. You should not go through and quit every app you open multiple times a day. There is, however, an exception to this rule. Apps that are actively doing something, such as navigation apps or playing music (i.e. Spotify or Pandora), should be paused as they will drain the battery, but even still, there is no reason to quit them completely.
