Question Install widget of the lockscreen on the launcher

Hello,

I use Archidroid 1.7.16 which is for me the actual best rom for the i9300.
However, i'd like to put the clock which is on the lockscreen on the pages of my launcher because it's very useful to see the next alarm.
I've used Chronus for a while and it worked well at the beginning but caused a big drain of battery after a few days. I've tried to reinstall the rom and chronus several times but the same problem of batery came back each time.

Can someone have a solution ?
Thanks
