I don't use many features on my iphone. Mainly:
1.Phone calls and messangers
2.Trading crypto
3. News
4. Payments
Major use of my phone is also phone calls and messages. Not into social media so I don't have much clutter in my phone. But I do have apps like for food delivery, a ride-hailing company, one e-commerce app and that's it. As much as possible, I want to have a simple life without too much things to attend to. Ah yes, I read news also.
