Smartphone encryption uses TPMs to keep keys out of RAM and to limit thieves/police to 9 PIN attempts before wipe on failed attempt 10. If you care about your phone being encrypted you benefit. If you wipe a phone with just a few taps thanks to key destruction instead of waiting for a full TRIM run you benefit.

On the negative side requiring TPM to install Windows 11 is planned obsolescence that greatly outweighs any perceived platform level security Microsoft promises. A lot of e-waste will be generated ahead of the Oct 2025 sunset of Windows 10. Who really believes Microsoft is fighting for user security like Google did when they proactively sunset SHA-1? Platform security also means bank apps refuse to run on rooted phones. Some online games have metastasized from kernel extensions to TPM verified hardware IDs.
