Wow, I respect your organisation! I'm afraid the circumstances that cause me to switch phones vary wildly. Here is a chronological snapshot of how long I use my phones and why:
- Transitional periods - when I was going from middle school to high school, I got my first smartphone. So I suppose my first phone lasted 1 or 2 years? I didn't really use my phone very much (astounding how times have changed!) but my parents thought it was appropriate for me to buy a new phone, particularly since everyone else seemed to be getting smartphones
- Broken/Lost - Unfortunately, I'm super clumsy. To this day I have broken the screen of my Kindle after 2 years, fractured my laptop screen within 2 years, had my LG G4 die on me after 1 year (manufacturing problem, at least!) ... I wish I had something more concrete to work on than just being more careful with my devices, because it seems like such a nebulous/unhelpful plan! Anyway, I learned my lesson and bought a fantastic Otterbox case for my last mobile phone.
Even then, I lost it. Not once, but twice - and both times in a taxi! The first time, I was extremely lucky and got it back. The second time, well. That's why I switched phones after 2 years.
What's so terrible about this - yes, it can get worse - is that I know I'm being extremely wasteful, both with resources and money, and I don't want to contribute to the hyper-consumerist culture prevalent in tech circles... I actually think I overuse my phone and could go without one for a while. However, my parents are very adamant about being able to reach me at all times. My dad is also very into technology, so he wants me to buy a new device every few years, particularly
for milestones (e.g. starting university).
Regardless, I'm determined to be more conscientious and use my current phone until it breaks down purely by itself. Since my phone is fairly new, I'm not sure how long it will last because I'm suspicious of manufacturers these days. It really seems like there is a higher probability of your phone breaking down after only a few years these days...
Though I want to hang onto my possessions for as long as possible, this mindset is a little more challenging for technology (phones in particular) because I can spend weeks looking up new releases and comparing them! There's just something so exciting about being wowed by the latest flagships and breathlessly watching benchmarks...
But I will resist.
