Hi,
I have Macbook pro 2014, recently I upgraded it from El Capitan to Sierra and I noticed that battery got drained faster, on El Capitan it was stay more than 6 hrs. with continues work but now on Sierra if it stay 3 hrs. it will be good, Also I suffering from lags after that upgrade!
I searched for rolling back to El Capitan but most of topics said that I must have an El Capitan time machine backup, but I didn't do this.
>> Is there any way to revert this awesome El Capitan again without losing my data?
Thanks in advance.

1. Have you installed all current updates to Sierra?

2. If so, have a look at this article and try the suggestions there before downgrading: osxdaily.com/2016/11/30/macos-sierra-battery-life-drain-tips/

Apple do have a habit of making it difficult to downgrade once you have updated the OS. Without a backup of the El Capitan installation it is going to be difficult and there is a high probability of data loss (although that is always true if you don't have a current backup).
