Actually battery is spoiled by 2 things.You're not alone. I use normal charging most of the time, only fast charge when I'm in a hurry, which is not often.
Heat and in either v full or v empty state.
Slow charging helps by not generating heat. But actually if u fast charge in a cool environment like air con place also ok.
Stay empty or 100 percent full too long actually physically strain the battery hence it spoils easily..aka bloated battery. Hence charging overnight and letting it stay at 100 percent always is as bad as leaving it empty.
Anyway.. change battery cheap la. Oneself change 15 bucks. Shop usually 50.
Use normally. Battery tech v good now..u toture the battery for 2 years it is still v good.
