Lithium Ion batteries much appreciate a full cycle - drain to the last drop then fully recharge, as the predicted life-time is a function of this state.
This practice might work for a few select applications such as cell phones, but in laptops the typical usage is actually works AGAINST this battery chemistry (as soon as you plug in the battery starts to charge!)
I would not worry about how long the battery is functional - I would more worry about if there is a replacement. For about two decades now I buy, and I recommend all my friends and family to buy, laptops alongside with one maximum-capacity replacement battery. The battery-replacement business seems to have improved over the years, but I still like to have one installed in the laptop, and I carry the other ready to be charged.
If this is a new laptop you bought, and you are able to afford it you probably should buy one extra battery as well.

If You notice Battery would get drain once it reached 5-10% level since it would be discharging some amount even it is not connected to the laptop or if the laptop is turn off so it is not proper to wait until it get drained completely.
The reason is that if the battery is unused for months without any charge then it would lose the ability to store charge.
