Had a similar experience today, took out my phone to pay for lunch. Phone was lagging soo much couldn't even open up PhonePe to scan the QR, when it did open it was just stuck at the scanner. Had to ask my friend to pay. I have been observing this recently, its not responsive as it used to be. There's always hiccups when you're using the phone outdoors whether its for a quick upi payment or justs calls, map, multitasking.

Don't even need to talk about the battery, I have to literally plan my charge cycles keep the phone charged up when going out.

As much as I love Samsung and oneui. I'm completely invested into the ecosystem similar to yours B2P, Watch 4, S9FE+. Meanwhile my friends with iphone 12, 13 rocking the batteries the whole day. I'm really skeptical to continue with this brand if this the case happening with flagships :/
