However, keeping your phone connected to the network all the time may result in poor performance, but it’s not enough for you to even notice. Drip charging – what your battery gets when it’s plugged in and fully charged – is far less damaging to the health of your battery than draining too much. This is because your gadgets, the batteries in them, and the chargers you plug them in are actually quite smart and business-friendly. Contrary to what you might think (or have been told), leaving your phone or laptop plugged in at all times is not bad for its battery. What is not a problem is the overpricing. Speaking with iFixit tech writer Andrew Goldberg, Popular Mechanics said the following :

When you plug your phone into the mains for an extended period of time, old lithium-ion batteries can overheat (or explode, in rare cases), which in turn simply reduces the charge capacity and long battery life (this can still happen if you have a cover that prevents heat dissipation).Ĭhargers and smartphones are smart enough these days to prevent this from happening. Just like calibrating a battery, it used to be possible to ruin a battery by “recharging” or leaving it plugged in at all times. Myth: Charging the battery overnight will shorten battery life. This is considered a complete charge cycle, which in turn shortens the overall battery life. It’s really bad for lithium-ion batteries to discharge to 0% regularly. However, you shouldn’t do this too often. If you see that your phone’s battery percentage fluctuates a lot (for example, you could swear it was fully charged and now it is 20%), it’s time to calibrate it. These “smart batteries” supposedly reduce the need for calibration, although it’s still recommended when your battery is behaving strangely. However, more and more batteries have a digital calibration tool built in.
HOW MUCH BATTERY LIFE IS USED OVERNIGHT FULL
Discharging to 0% once a month helps the operating system calibrate the full battery life so it knows exactly how much it has decreased over time. Basically, each discharge will shorten the battery life slightly. As the overall life of your battery decreases over time, the time remaining for each full charge decreases slightly with each full discharge. Most manufacturers still ask you to “calibrate” your battery by discharging and recharging it every one to three months. Apple Li-Ion batteries are designed to retain at least 80% of their original capacity over multiple charges, which vary by product. For lithium-ion batteries, the capacity decreases slightly with each complete charge cycle.

The capacity of any type of battery will decrease after a certain amount of recharging. It may take several days for the cycle to complete. If you use 25% the next day, you will discharge a total of 100%, and in two days you will have a total of one charge. For example, you can use 75% of the battery capacity one day and then fully charge it overnight. You complete one charge cycle when you have used up (discharged) an amount equal to 100% of your battery’s capacity, but not necessarily all in one charge. Apple lithium-ion batteries operate in cycles. There is no need to let it fully discharge before recharging. This is how Apple explains it, and while they refer to their batteries, the rules apply to any lithium-ion battery:Ĭharge your Apple Li-ion battery anytime. Likewise, lithium-ion batteries count charges differently than older batteries, so you don’t have to worry about completely discharging them. Smartphones today have lithium-ion batteries, which do not suffer from the memory problems of old nickel-cadmium and nickel-metal hydride batteries. This is no longer the case, and it was not so long ago. Thus, you will have to let the battery fully discharge to 0% before charging it again. Old batteries will “forget” their full capacity, so they cannot be fully charged again. Myth: the battery must be completely discharged before plugging in.īatteries used to be blunt.
HOW MUCH BATTERY LIFE IS USED OVERNIGHT BLUETOOTH
Before telling someone to turn off Bluetooth or Wi-Fi, let’s shed some light on these old myths. This means that these old tips for extending battery life are not as true as they once were, but we still share them as if they were the gospel. In just a few years, the batteries in our smartphones have changed a lot.
