There are some issues with the battery of Yureka. Follow the steps below -
1. Check the battery status. If your status shows Mediaserver shows up as the highest battery drainer, it should mean your media storage has some issues.
2. Go to Settings -> Apps-> All , then select Media Storage and Clear Data.
3. Disable the app, reboot. Re enable it and reboot again.
Apart from this, you can follow the usual methods as on any Android phone. Some of them are -
1. Remove useless apps
Remove any app that you seldom use. The apps have background processes running which drains battery.
2. Limit background process
Go to Developer options under settings and limit the background processes to a maximum 2 or 3.
3. Avoid using too many widgets
Homescreen widgets keep the apps running in the background. Remove those widgets which you tend to use less.
4. Optimise sync
Set your email sync or any other sync to a higher interval. A setting of 4 hours will be ideal.
Live....and Let Live!
