Smartphone battery has limited lifespan and it will eventually degrade over time. However, there are some habits that may shorten the lifespan of your battery. One potential problem is that your battery will have shorter lifespan if you charge it overnight. Major smartphone makers are not too concerned with the habit of overnight charging, because they claim that their devices have a mechanism to protect against overcharging. However, it doesn’t mean that you should charge the phone for too long. Overnight charging after the phone reach 100 percent could accelerate the aging of standard Lithium-ion batteries.
Your phone will be fully charged in just 2 or 3 hours, depending on the battery capacity. If you sleep about 7 hours each night, it means that your device is charged for more than five hours at full capacity. When Lithium-ion batteries age, their internal chemistry will change, making it less efficient for them to store and deliver power. Surely, no matter how careful you are, batteries will degrade permanently, but it’s important to limit the aging process. However, smartphones agree that if you plan to store your phone, you shouldn’t do that with the battery fully charged. In other words, smartphones batteries won’t take it so well being left for a long time fully charged.
Experts discover that the aging process happen the most slowly when the battery between 30 and 50 percent capacity. So, it’s the most appropriate range if you want to store your smartphone for a week or more. In fact, Apple already advised that if you need to store the iPhone for the long-term, you need to do it with half-charged battery. This should help to improve the overall battery lifespan. Perhaps, a good solution is to charge your phone at 7PM and spend the time with the family. After, it’s fully charged, you can use the phone for 15 minutes and then go to sleep.
