We do not know what the bars show. If 3 bars is fully charged then we do not know what 2 bars is. 2 bars might be when the battery is close to the 3.2V warning or the 3V minimum allowed.
Charge it to 100% then remove the battery and let it sit for one hour then measure its voltage.
Then install the battery and use it until the display shows 2 bars, remove the battery, let it sit for 1 hour and measure the voltage.
Report the voltage measurements here.

This is going absolutely nowhere ....advice you've been given seems to be ignored.
If during the use of the device the charge reaches 0% or close to 0% the useful life of the lithium polymer battery is reduced or the useful life is reduced only if it stays at 0 or close to many days?
if I recharge the lithium polymer battery to 100% and use the device, will the useful life be reduced or will the useful life of the lithium polymer battery only be reduced if I store many days by 100%?

www.batteryuniversity.com answers most of your questions about a lithium rechargeable battery but they don't know the product's charger or anything in the product (a clock?) that is draining the battery for 3 months.
They say that if a Lithium cell's voltage has stayed long at a full charge voltage of 4.20V then its life is shortened. They say that if it is discharged below about 2.5V or 3V then it is ruined.
They say that if you do not use it for any amount of time then the battery will last longer if it is stored at 3.7V to 3.8V.
The battery also has a limit for the number of charge, use then recharge. About 500 times.
My lithium rechargeable batteries are stored all winter at 3.7V then used about 100 times each summer. They last for 4 to 5 years.
A friend of mine bought 10 Cheap Chinese lithium rechargeable batteries. 5 did not work and the others lasted only for a few times.
Nobody knows what the bars on your product are showing.

That you stop posting the same request repeatedly.
You have already received advice, which you have chosen to ignore.
