Question Which one is better option to avoid battery wear level?

[PeyoteFTW]

Option 1
Use laptop until battery 95-90% and charge it
Option 2
Use laptop until battery 60-50% and charge it

And another question if your battery indicator show 100% fully charged, does laptop will automatically cut the power to battery and deliver the power directly to laptop hardware?

It shouldn't make ANY difference what level the battery is at when you plug the charger in so long as you don't let the battery completely discharge and then sit with no charge for long periods of time.

Yes, your laptop will stop charging once the battery is full and after that will only supply whatever the laptop wants to eat.

We should periodically fully discharge laptop batteries and then give a full charge. It hurts batteries if they are kept at full charge always and never discharged.

I'm sure you're talking about a specific KIND of battery, and not batteries in general across the board, since the state of charge and charging practices for batteries is completely different from one kind of battery to another. Lithium ion batteries for example, do not EVER need to be fully discharged, as they have no "memory".

Since most laptops use lithium ion batteries these days, you advice is completely opposite of the reality for most uses although you are correct that occasionally a full discharge is recommended. Let's be clear that this is a "once per 30 charges" type situation though, and not the general rule.

3: Allow partial discharges and avoid full ones

Unlike NiCad batteries, lithium-ion batteries do not have a charge memory. That means deep-discharge cycles are not required. In fact, it's better for the battery to use partial-discharge cycles.

There is one exception. Battery experts suggest that after 30 charges, you should allow lithium-ion batteries to almost completely discharge. Continuous partial discharges create a condition called digital memory, decreasing the accuracy of the device's power gauge. So let the battery discharge to the cut-off point and then recharge. The power gauge will be recalibrated.
