We often hear that leaving your phone on charge all night affects the longevity of our battery. But is this really the case?
Who are we? Where do we come from? Where are we going? Here are three fundamental questions that no one seems to be able to answer. Immediately after comes the question: Is it true that we should not charge our phone overnight?
The lithium-ion batteries in our smartphones age and hold less of a charge over time. That’s why your old phone drains faster. The sad reality is that the batteries in our smartphones “get used to” and no one wants a phone that has to be constantly charged.
This is where the idea that leaving your phone on charge overnight is a bad habit for battery life comes from. But is it really true or is it just an urban legend? Perhaps the best way to find out is to ask the manufacturers directly. Apple says that when the iPhone “remains fully charged for long periods of time, battery health can be affected.”
Android phone makers say the same thing. “Do not leave your phone plugged into the charger for long periods of time or overnight,” warns Samsung. Huawei adds, “Keeping the battery level as close to the middle as possible (30%-70%) can effectively extend battery life.” In other words, the ideal would be to keep the phone with some battery – but not too much battery.
The battery automatically stops charging when full, but in some cases when it drops to 99%, it needs more power to get back to 100%. This small constant recharging affects battery life. Most phones have load-regulating options for this reason.
In the case of iPhones with at least iOS13, optimized charging reduces the time the phone spends fully charged. The smartphone analyzes your charging habits and waits to exceed 80% until needed. There is also a very simple trick to implement. You can plug a timer into your phone charger. Set this timer so that your phone only charges for a certain period of time. For example between 3 a.m. and 5 a.m. And like this, you will prevent your phone from charging then discharging and charging again. In the morning, you will only have 95% battery but it will be less serious than having damaged it!
