>>>tried watching videos, video also gets stopped and again continues.>>>

In less than a half-hour, the videos and other processes seem to be consuming about 30% of the battery capacity. This is quite high. And suggests the battery alone can't keep up with the power demand. So it needs help from the charger to meet the power demanded by the videos and whatever other processes are running in the background.. Please post a screenshot of the top sections of TaskManager Processes and Startup tabs to see if anything else other than the videos are consuming so much power.

>>>This was my currwnt tsate of tasks>>>

Were you running the videos when you took this screenshot?

>>>No j was downloading something>>>

We need to see the screenshot when you're actually watching the problem videos.

>>>Problem happens everytime on battery>>>

Yes, I understand that. So please post a screenshot of TaskManager Processes tab while problem happens on battery.
