Charging your mobile phone overnight can do alot more damage than good, and here’s everything you need to know.
All this while, you might’ve been thinking that charging your smartphone while you’re asleep in order for it to hit 100% as usual is good for your mobile, but the reverse is actually the case because it harms your battery and shortens its life.
Here’s the truth about maintaining mobile phone batteries – and why you should stop the habit of charging it overnight.
How Is Battery Life Expectancy Determined?
Everybody wants their tech to be usable for as long as possible, and you should know also that warranties are invalid if you tamper and/or fiddle with your device(s).
It’s a known fact that rechargeable batteries lose their capacity and strength slowly over time, whether used or unused. It usually starts being noticeable after one year of use. For a high percentage of smartphone users, getting through the day on a single charge is almost impossible beyond the two-year mark.
Lithium-Ion (Li-Ion) batteries are used in a great percentage of rechargable techs. You can find some form of Lithium-Ion batteries in vaporizers, smartphones, Teslas, laptops, and even chainsaws.
Why Do Rechargeable Lithium-Ion Degrade?
Tablets and mobile phones use a variation of Li-Ion battery called Lithium-Ion Polymer (Li-Poly). This version is smaller, safer, and charges much more faster. Otherwise, the same lifespan rules apply to Li-Poly as with any Li-Ion battery.

Note!!! Your battery degrades fastest when you charge it regularly past 80 percent and let it drop below 20 percent. Your device operates best at 50 percent charge. Avoid extremes (100%, 90%, 5%, 10% etc) to extend your battery life.
How To Look After Your Smartphone Battery
You might have already gotten into bad habits when dealing with charging your phones, tablets, and other technological devices, like plugging it in while you sleep. Good for you, it doesn’t take much effort and time to correct these bad habits.
It might take an hour or so to charge your mobile, but leaving it plugged in during sleep means it’s connected to the charger for a longer period of time.
For knowledge purpose, your phone battery can’t overcharge. The device manufacturers already put standby safeguards in place to prevent that scenario. However, when it hits 100 percent, it also “trickle charge,” i.e., enough extra energy to compensate for whatever your device uses by default. By charging to 100 percent and keeping it plugged in after that, you’re overusing your battery and stressing it out at thesame time, forcing it to expend energy when it need not to.
Prolonged charging of your phone, especially overnight could possibly lead to an increased temperature of the device also, which will naturally degrade your battery really fast. It can also be dangerous in extreme cases—especially if you keep your phone under your pillow.
Avoid exposing your phones or any of your technological devices to any extreme temperature. Temperatures below 32 Fahrenheit (0 Celsius) and above 158 Fahrenheit (70 Celsius) degrade your Li-Ion battery faster.
Can You Use Apps While Your Phone Is Charging?
Using your device for high-intensity activities while its charging isn’t advisable, but realistically, many people fall in these shoes. Nonetheless, regularly doing so can cause irreparable damage to your mobile phone battery, and sometimes the device itself.
It is comparable to overclocking your PC’s CPU. Imagine the effect of having too many applications running at the same time: it will definitely heat up and not operate properly.
How To Reduce Battery Drain on Your Device
Asides regulating the temperature and charge percentage of your smartphone, you can further extend its battery life by reducing the frequency of you charging it. Fewer charges mean fewer cycles, leading to a longer life for your device.
Reducing the screen timeout duration and turning down the brightness settings will have the biggest impact.
How To Store Your Smartphone Batteries
If you intend not to use your mobile for a long time, you still need to look out for your batteries.
- Limit exposure to extremes (too cold, or too hot) in storage
- Keep in a cooler place
- Don’t charge it to 100 percent before storing your smartphone
- Reduce the battery drain of your device by turning off unnecessary services.
- Use battery savers to get even longer use from every charge.
