6 FAQs about [Does the battery have to run out for the first time ]

Why does a battery run out when you first test a device?

Because when you first get a device , you spend a long time configuring it and testing it. When you first test the device it gives you a "first impression" of the device. The battery WILL run out. Running out sucks :-)

Should you charge a lithium ion battery first?

There is no reason that charging a Li-ion battery up the first time before playing with your new device, would in any way extend the life of the device or the battery. The simple fact is properly stored lithium-ion batteries are charged to about 50%, and lose some of that charge (depending) while sitting around in the package, or being shipped.

Should you let your phone run out of battery before charging?

In fact, it's better to charge your phone overnight rather than letting it run completely out of battery, as this can help prolong the battery's overall lifespan. Myth #2: You should let your phone's battery drain completely before charging it. Truth: This is actually a myth that dates back to the early days of phone batteries.

Should you turn off a battery if it's not in use?

Modern batteries are capable of reading their state no matter their level of charge, and when your device isn’t in use the strain on the battery is almost the same as if it was off altogether, so you wouldn’t be giving the battery much of a break if you turned it off anyway. False (mostly) Actually, the opposite is true.

Should I charge a battery before leaving it in a device?

If when you get your device, the battery voltage is so low that your device will not operate, you should definitely charge the battery, before leaving it in said device. The battery should not have come to you in that condition, and would be a suspect battery at that point. The low voltage protection could have saved it mostly still anyway.

Why do batteries need to be charged a lot?

Increasing the available charge within a battery reduces the number of times that battery can be charged and discharged without being damaged internally. To make batteries last for hundreds or thousands of charge cycles, manufacturers place limits on the amount of juice that batteries can discharge.
