I recently got a PartyBox 720, and I love the speaker. I’ve installed the JBL app, and it’s suggesting a firmware update. Some people say you shouldn't update it because the bass gets reduced, while others say it's better to do the update because less bass puts less strain on the drivers, helping the speaker last longer. Which is right? I only use it indoors—mostly at volumes below 30%, though sometimes I turn it up briefly.

Hello I had a Problem whit my iPhone 11 Pro

It Shows 100% Batterie but sometimes it dosent last a Day and some time it Only Charge up to 80-90%

I want to pay less Money as possible and the iPhone 11 is enough for me Need it just for work
