When change contact information the lumia 1520 starts draining battery with windows 10 phone.

[Windows Central Question]

I found something strange happening. After I updated to win 10 phone sometimes the battery holds two day with my normal usage and sometimes the phone starts draining uncontrolably and I have to restart it to start acting normal. Recently I noticed that the process starts after I change something in the contact information. The battery information is that the most battery-using apps are "people" and "call" with above 20% usage each. I think this is too much. Do you think it has something to do with system starts infinite cycles or something?
It's very annoying! I have to restart the phone each time I have to change some contact information.

check that the two apps have the latest updates from store
Secondly, go to settings > privacy > background apps and check if people app is enabled to run in the background - disable it
