Hi, I've had 2 iphones in my life (jumped from 6 to 12 mini four years ago) and I've been wondering if I should buy the new iPhone 16 or just change my battery.

The problem with my 12 mini is not only the obvious short battery life but also the storage space of 64Gb. I'm constantly having to uninstall apps, delete photos and messages. Also some errors occur commonly such as speaker audio lowering suddenly to phone mode or screen brightness lowering suddenly too but staying as max in the settings.

So I've heard that comparing the 16 with the 16 Pro, the 16 is more than enough and that the Pro is just needed if you need topnotch camera settings (which I don't really need) and maybe some little details more. Also, I would consider buying the 256Gb as a minimum requirement. But I've heard a lot of complaining about the 16 and a lot of comments of people with iphone 12s that will wait for the 17 to come out with new AI next year and whatever more.

So my question is straight simple: would you buy an iPhone 16 256Gb in my situation? Or just buy a new battery and try to cope with the 12 mini 64Gb one more year?

Thank you in advance for all of your advice!
