nope the battery lifetime will be shorten more... charge  untill 90% only to increase the battery life

Lithium ion chemistry prefers partial discharge to deep discharge, so it's best to avoid taking the battery all the way down to zero. Since lithium-ion chemistry does not have a "memory", you do not harm the battery pack with a partial discharge. If the voltage of a lithium-ion cell drops below a certain level, it's ruined.

    Lithium-ion batteries age. They only last two to three years, even if they are sitting on a shelf unused. So do not "avoid using" the battery with the thought that the battery pack will last five years. It won't. Also, if you are buying a new battery pack, you want to make sure it really is new. If it has been sitting on a shelf in the store for a year, it won't last very long. Manufacturing dates are important.

    Avoid heat, which degrades the batteries.

They hold their charge. A lithium-ion battery pack loses only about 5 percent of its charge per month, compared to a 20 percent loss per month for NiMH batteries.

They have no memory effect, which means that you do not have to completely discharge them before recharging, as with some other battery chemistries.

Lithium-ion batteries can handle hundreds of charge/discharge cycles. 

    They start degrading as soon as they leave the factory. They will only last two or three years from the date of manufacture whether you use them or not.
    They are extremely sensitive to high temperatures. Heat causes lithium-ion battery packs to degrade much faster than they normally would.
    If you completely discharge a lithium-ion battery, it is ruined.
    A lithium-ion battery pack must have an on-board computer to manage the battery. This makes them even more expensive than they already are.
    There is a small chance that, if a lithium-ion battery pack fails, it will burst into flame.
