OG Pixel XL not vibrating

[Woah Boy]

Alright so as some of you may know ive recently bought a pixel xl cause it suits my needs , but the battery life was TERRIBLE coming from my other phone, after being recommended to try the android beta program i installed and after 1 day had my avg battery life jump from around 17 hours to 1 day and a half, but heres the catch, im not sure when exactly it happened, but my phone dosent vibrate ONLY when getting notifications, but it will for calls or alarms, i know this is probably something to due with the beta of course, but im looking for a solution without having to revert back to oreo, i cant use a phone with battery life that dosent last me a day of heavy usage
