there are many panics. it just blackouts then i see the apple logo

If you do see panic reports, restarts are happening at random using different apps and completing different tasks, your device very likely is having some undergoing hardware issue and needs to be serviced. If that is the case, see https://support.apple.com/iphone/repair/service.

Does it restart at random tasks? Or always when you repeat same sequence of steps and while using same app or feature?

How does it restart? What do you see on the screen during the restart? Do you see screen with an Apple logo?

If you go to Settings > Privacy > Analytics & Improvements > Analytics Data, do you see any records on the list starting with word 'panic'?

83% Maximum Capacity is not good. Shutting down can be a symptom of a battery in need of replacement:

"...The power management system determines the capability of the battery to supply this power, and manages the loads in order to maintain operations. When the operations can no longer be supported with the full capabilities of the power management system, the system will perform a shutdown to preserve these electronic components. While this shutdown is intentional from the device perspective, it may be unexpected by the user." [Source: Apple]

…So consider having the battery replaced:
