This isn’t even an iPhone vs. Android debate. This is specifically about Samsung. They have the worst “budget” phones on the market, they deteriorate the fastest of any of them. With each update the previous iterations of the galaxy line of phones get slower and slower until in two years they feel virtually useless. The battery management is horrendous, apps are allowed to eat battery for breakfast lunch and dinner. Including their own software apps. The Android skin is slow, clunky, and honestly ugly compared to stock android. If android is the route you want to go, Google pixel and one plus are much better options and will last you longer.

Sorry about my rant. Happened with 2/2 budget Samsung phones.
