for improve music bass

Sir,i have a micromax unite 2 ,but i want to improve music player with super bass . please help me .

Are there any roms that would improve battery life?

I have the Sprint Galaxy s6, which is fine phone, except the battery is awful. If I unplug it from the charger at 6am, it's down to 12% by 1. Would a new rom help? I haven't rooted the phone yet, but if it'll improve the life of it I'll do it.

I have small hands but I manage to use my 5.5 inch one handed, I have found this sticker (some kind of ultra grip gum), just stick it to the phone and hello super grip !
To fully cover the lg g4, I had to use 1.5 pack of those, so you should buy two of them.
