Installing is an energy consuming process, and a current battery status does NOT predict the REAL time left for usage.
It's better to begin a fresh install now, forget about upgrading.
Make certain that you do not format partitions with data that was not yet backed up, such as your /home partition.
And last but not least, keep the charger plugged!
Thanks a lot. I had to go for about 6-7 hours and as far as I know over charging Li ion batteries decreases its life. So I took a risk and it didn't pay off.
As far as data was concerned I have already backup it using live USB. Yeah I will do a fresh installation but actually my main motive for posting was to learn about this as I am a Btech student and a lot of stress is given on Linux.
So still if there is something I can do to save or learn or even can know How and why this problem came, I would love to.
