Currently im using iphone 13 256 with BH 87 … Thought of upgrading to iphone 14 pro 256 or 15 Plus 256… Both came for great deal under 90k ( Used but with 10 months apple warranty)…
Hi bro, 14 Pro will be good upgrade to get that 120Hz ProMotion Display and 1 or 2 hours extra battery backup according to your usage compared to iPhone 13 model. Taking it with warranty is always good idea.
you may consider iPhone 15 Plus if 60Hz display is ok for you but higher priority to that bigger display, usb c port and bigger battery performance. otherwise 14 pro for its comfortable holding and usage. If 13 battery is sufficient for your every day usage then go with 14 Pro. else 15 Plus.
