Nothing in general have optimisation issues. Earlier I was using a Samsung S23 which had a 3900mah battery, I had to charge it 2 times a day. With my NP3, it is 1.5 times a day with two Sims and wifi. Moreover it gets warm (not hot) in normal usage. And if you spend an hour using its camera, it gets hot. For the current price of 40-45K, it is a decent phone but if you already have a 4a pro then there’s no point in switching and wasting money. Better switch to older Samsung flagships or Vivo… even with bloatwares their OS are better optimised.
