Charging our phones every night is now a routine. We charge our devices at night and wake up with a full battery. However, people are still concerned if it is secretly ruining the battery. The truth is, modern smartphones are equipped with smart charging systems that automatically prevent overcharging by halting charging when the battery hits 100%. So, overnight charging is unlikely to do substantial damage.
Nevertheless, there are a few things that impact your battery’s longevity. Minor habits, such as keeping your device cool and preventing full charge and discharge, play a significant role.
Understanding How Overnight Charging Affects Battery Health
Heat is Primarily the Problem
More than charging time, it’s heat that causes real damage. Charging your phone when you are in a hot room, or wrapping a blanket around it while it is being charged, allows heat to accumulate inside. This heat accelerates battery ageing and shortens its life. So, try at all times to charge your phone in a cool, open area. It makes your battery safe and longer-lasting.
Leverage Intrinsic Battery Cap
Today’s phones include smart features such as Optimized Battery Charging (on iPhones) and Adaptive Charging (on Android). They are designed to help shield your battery. They decelerate charging, cap how often your phone reaches 100%, and adapt based on what you do every day. Enabling them helps keep your phone performing optimally for longer.
Don’t Let It Hit Zero
Letting your battery drain completely down to 0% may be acceptable, but it is not advisable. Repeating this regularly will strain the battery and cause it to deteriorate more rapidly. Try keeping the battery at a level of 20% to 80%. This preserves battery life and extends the life of your phone.
Avoid Removal of Case During Charging
Phone cases trap heat during charging. If a case is thick or poorly ventilated, it will heat up your device. Taking it off while charging keeps the phone cool and reduces damage risk for the battery.
Final Thoughts
Smart Flick suggests that overnight charging is generally okay due to smart features. Charging in a cool location, avoiding 0% or 100% charging, and removing the case while charging are all smart things you can do. These are easy habits that keep your battery healthy and your phone performing for longer.
