I am sharing my observation to overcome the battery draining issue in Asus zenfone 2 laser. These tips may help for someone who faces the battery draining issues.
The most of the battery draining issue is because of third party app installation. My suggestion would be don’t install all the third party apps at a time. Install one day one third party app and see the battery draining issue i.e. While going to sleep check the battery percentage and see the battery percentage in the next day. If the difference of the percentage is max 4% then that third party app performance is good
While doing the update for third party app better to completely uninstall the app and install the app
Clean the cache data after uninstall the third party app and then install the third party app.
All the third party apps should be placed under the Super Boost list and enable the super boost option
Use Mobile Manager Scan option which will show the background running apps and close the background running app which will save battery usage
Change the battery option to power saving mode
