Before going to sleep, you may want to listen to your favorite songs or chat with your friends using your smartphone. After a long day, it’s likely that your phone battery is as worn out and as tired as you are. Before you go to sleep, you may wonder…Is it a good idea to plug your smartphone into its charger overnight so that when you wake up in the morning, it will already be fully charged and ready to use again? What about the claims you may have heard that charging a phone overnight will damage its battery and reduce its capacity over time? Is there any truth to these claims?
First of all, yes, you can leave your phone plugged in overnight with no worries about damaging it. Read along to find out why…
Reasons to safely charge a phone overnight
One of the reasons why you can charge your smartphone overnight without damaging it is that today’s phones and devices use Lithium Ion batteries. Unlike nickel-based batteries like Duracell and Energizer, Lithium Ion batteries do not suffer from cyclic memory. Batteries with a cyclic memory like nickel batteries may “forget” their maximum capacity when they are not fully charged in between cycles. They register only their last charging level as their maximum capacity. This is the reason why nickel batteries seem to discharge power very fast over time and quickly wear out their effectiveness.
Another reason is that newer smartphone technologies have advanced battery power circuit protections. These smart technologies can effectively maintain the good health of a smartphone’s battery due to their power optimization capability. The main danger to batteries left for long periods on a charger is overheating. However, newer smartphones will automatically stop charging when a full battery charge is achieved and then switch to using the connected charger as its main source of power. This also allows your phone to remain ON through the night while maintaining the fully-charged state of its battery.
So, now you can rest easy knowing that it is perfectly safe to charge your phone overnight. However, some of your charging habits may have adverse effects on the health and longevity of your phone’s battery. To help keep your device’s battery healthy, here are some tips that you can adopt…
Best charging practices for smartphones
- Try to avoid a complete charge-and-discharge cycle of the device’s battery as much as you can to prevent the reduction of its capacity. To do this, you should keep the battery’s charge level between 40% to 80% power. Try NOT to let the phone’s battery discharge completely.
- Avoid using the fast charging option every time you recharge your phone. This is because the majority of fast or rapid charge systems heat up the battery significantly. Using fast charging every time may reduce battery life.
- Always use the recommended charging cable and a high quality charger with built-in protections against overheating, overcharging and overcurrent.
Understanding the characteristics of your phone’s battery and applying the proper charging techniques can help to extend the battery capacity and lifespan of your mobile phone or device. Feel free to plug in your smartphone overnight and wake up to a fresh day with a full charge to get you moving.
