Cheaper Samsung phones shut off, thought Samsung has SO TERRIBLE BATTERIES it's not even shameful, they should be sued! Every battery puffs up after 6-12 months

Cheaper Samsung phones shut off, thought Samsung has SO TERRIBLE BATTERIES it's not even shameful, they should be sued! Every battery puffs up after 6-12 months, and the warranty only covers first 6 months of usage. I know many people to whom it happened, to some multiple times, and they didn't drop the phones. This was with cheap phones obviously, but still, very bad behavior from phone manufacturers on all sides... :/
