I honestly just study during times when I know I'm too tired to want to scroll, like in the morning when I wake up, because your brain has less willpower to resist temptation! Plus, try putting your phone in grayscale: without colors, apps become way less addictive and lose that visual hook that gets you. Combine that with 25-minute timers for focused work followed by 5 minutes where you actually let yourself check whatever you want, so your brain knows the reward is coming and holds up better. What almost everyone says about blocking apps is fine, but most people end up unblocking them five minutes in when they get bored, so the psychological trick of "I can do it later" works better than total prohibition!
