Does dark mode save battery?

Yes, dark mode can help save some battery power. When used on an OLED display, dark mode saves 3% – 9% power on average when the screen is set at 30% – 50% brightness, and can be helpful for saving the last remaining battery when it’s already low.

How do phone batteries work?

Phone batteries work by storing electrons from your connected power source. While you charge your phone, electrons attract lithium ions. These ion particles move inside the battery from the cathode to the anode, powering your device. As you use your phone, the ions return to the cathode; once they’ve all returned to there, your battery is 'dead'.

How long do phone batteries last?

On average, the estimated life of a lithium-ion battery is around two to three years, or 300 – 500 charge cycles. One charge cycle is when you charge your phone battery and then use it until it dies and needs to be recharged.

Do notifications make my battery drain so fast?

Just like any other type of activity, push notifications can drain the battery on your device. Notifications can be especially draining if they cause your device’s screen to light up with each alert. Depending on your settings, each alert may also trigger a ringtone or vibration, which also uses battery life.
