Tick updating at different rates on iOS vs Android/PC

Hello, I am having an issue where a CPU particle emitter is told to generate particles so long as the player is clicking down. It also deprecates from a total meter. When the meter runs out, the particles will no longer emit. On Android and PC, the emitter produces a generous amount of particles and the meter deprecates at around 10 units per second. On iOS, the particles generate at about 2 per second and the meter deprecates at around 2 units per second. What could be causing this discrepancy between the updates on platforms? I would like it to perform as it does on Android and PC.

Thank you!
