I own a Lenovo Y500 series laptop.
The battery being an year old lasts only 1 hour.
But the strange thing is that, when the charge comes down to 25-20 it drops to 6%(critical battery level) in a moment.
Please suggest some solution (other than replacing the battery).
P.S. : I do many battery saving things already, like lowering brightness, switching to power-saver mode, turning off 'aero' on windows, etc.

Sorry to say it, but I don't think there's another answer to be had; what you are experiencing is usual for a battery that needs replacing.
Their expected life-span is only about 1 year (according to the manufacturers).
The reason the readings act weird is because when the battery becomes old and faulty it can't properly gauge the total capacity or current charge, so the gauge readings are based on inaccurate numbers.
