I’m iPhone user since 2015, and with every replacement (6, 8, 11 Pro) I have doubled the storage: 128, 256, 512. So this has allowed me to keep all my data since my iPhone 6.
Back on December 2019 I got an iPhone 11 Pro Midnight Green with 512 GB.
Unfortunately after 5 years of rough and loyally use, the battery of my 11 Pro has been degraded to 74% and has been very hard to finish the day without charging at midday. Also the lightning charging port stop working 2 years ago so the only way I’m able to charge it is through a Qi “wireless” charging base…. what drive me nuts when I’m away from home or my office.
So this year I became my own Santa and gifted myself a brand new iPhone 16 Pro White Titanium with 1 TB!
I’m very glad with my purchase although being honest, I haven’t found too much differences between my new 16 Pro and my old 11 Pro. Ok, better camera, larger screen, but nothing very special that had justified the update beyond my issues with the battery and the lightning charging port which by their own were enough reasons to update.
I expect my new iPhone should last me at least 5 years more. The only way I would update before is, if Apple launches a flip or foldable iPhone which I would buy since day 1.
