1. Using Your Phone While It’s Charging
When your phone is charging, it’s best practice to leave it alone and not pick it up until its charging session is complete. Using your phone while it is charging adds heat to your battery and device, and this will degrade your battery over time.
2. Charging Your Phone To 100 Percent
There’s no real need to charge your phone to 100 percent because the ideal charging zone is between 30 and 80 percent. To avoid overcharging it, enable Optimized Battery Charging, a setting that learns your phone’s charging behaviors to prevent it from charging to 100 percent too fast.
3. Letting Your Phone Battery Fall to 0 Percent
Remember that sweet charging spot we just mentioned? That applies when you allowing your battery to drop to 0 percent, too. It’s a better idea to give your phone smaller bursts of charging that prevent it from dying. Once your battery is dead, your phone requires more power and resources to start it back up again.
4. Cheap iPhone Chargers
Cheap iPhone chargers may save you a little money now, but they can cost you a lot more in the long run. Cheap chargers that aren’t certified by Apple are not designed to deliver the power your phone and its model needs. This can be damaging to your battery over time.
5. Charging Your Phone in Extreme Temperatures
Extreme cold and heat are death to an iPhone battery. Your phone is designed to function between
32°F and 95°F (0°C and 35°C). Anything outside of that range can put stress on your battery.
6. Charging With a Case On
It usually isn’t necessary to remove your iPhone case when you’re charging your phone, but if you find your phone’s temp is always hotter during a charging session, you might want to consider removing the case.
7. Charging With a Dirty Port
Charging your phone when the port is dusty and dirty leads to an ineffective charge. This may cause you to think you should keep your phone charged for longer, which can tax your battery. Clean the port with forced air or a Q-Tip.
8. Not Enabling Optimized Battery Charging
Optimized Battery Charging is a setting that is worth enabling for the sake of your battery’s longevity. This setting learns your charging habits so that it slows down charging until right before you unplug your device. This prevents the phone from reaching 100 percent and staying there, which can be damaging over time.
