Every time I get a new phone or smart watch it always states before first use please charge your device. Looking online I can only find that it supposedly improves battery life. Why is this the case?
In: Engineering
The device may have been in the box for 2 weeks or 6 months. The manufacturer can’t afford to depend on limited shelf time, for something complex like a phone. Simpler gadgets use a little plastic tab you pull out to activate the device, but those usually aren’t rechargable.
It’s “possible” that you could use it without charging it. However, startup processes could be interrupted if the battery was low. With something like a phone, these startup processes are very important, and failing to do them could brick the device.
So, there is a reason to read the manual and follow the instructions.
1) It ensures that the device actually has a functioning battery, and as a result if you have an issue it’s pretty easy to document.
2) Some batteries, because of the way their internal chemistry works, see benefits from getting a full charge, such that it can heal some damage done to the battery. At the same time, the phone sitting in a box for a long time period is something that actually does have the potential to harm the battery (from lack of use). Thus, charging it ensures that the battery is brought fully to life before you start having to rely on it.
