Don’t.

Two reasons:

Many employers require you to install phone-management software as part of the data loss mitigation/data exfiltration requirements - and those requirements might be set by their insurers.

This gives them the ability to remotely lock or wipe your phone at any time - useful to them because they remove company data if you lose your phone, or you leave the company, or are suspended for any reason. Obviously that’ll also lose any personal data on the phone, but that’s your problem, not theirs. They can also monitor its location and similar things.

That’s obviously a reason why you should never, ever, use a work-issued device for personal use - besides it being against their acceptable use policy. If your employer requires you to check email then they are required to issue you the means to do so. They cannot insist that you use any personal devices for that.

It’s bad for your mental health.

Keep work to work hours. Keep work devices for work. Keep personal hours and devices for your personal use.

This physical separation requires a little discipline but, having been on all sides of this barrier (employer, employee, suffering with poor mental health, and currently, in good mental health) - I know this to be the only way to achieve a health balance.

The best English literature doesn’t follow the basis of most convenient or shortest. Sometimes there are other reasons to choose a word of phrase.

The plot of Romeo and Juliet could be rewritten in a paragraph but probably wouldn’t have had the same impact.
