I've had HTC phones as my last two phones. My Incredible S lasted 5 years (and could've been used longer if the app storage wasn't so small on it). My HTC 10 is still going strong after 6.5 years. It's been repaired once, but I'm very happy with it overall.
I'm in a bind, though, as it's really hard to find phones that aren't largish. Right now, the Zenfone 9 is a pretty decent size for me, and it looks like the Zenfone 10 will be larger. I'm thinking of preemptively getting a new phone because I don't know when another good one will be available, and I don't know how much longer my HTC 10 will last. The only other option I'm considering is a Google Pixel 7 or 7a.
What is the expected lifespan of an Asus Zenfone? I'm a fairly light user, so I'm not constantly recharging it (my HTC 10 lasted 3 days when it was new; I'm still getting 2 days, but that's with a replacement battery). I never drop my phone, either. Can I get 6+ years out of an Asus phone? I've heard they had battery problems in the past. Has that been resolved? Also, how good are they at keeping parts and batteries available down the road (ie. 3 or 4 years)?
If you have any thoughts how the longevity of the Zenfone compares to the Pixel, that would be appreciated, too.
Good buy, now you have a discount in the official store, at least in Spain.
As far as buying Zenfone 10 or not, I would opt for the 10. The size is the same and it is only 0.3mm deeper.
Zenfone 9 will receive Android 14, its latest supported version. ZF10 has more years of official support and is important when you are buying at the end of 2023.
I'm delighted with my ZF9. Good battery life and a very light Android environment and close to pure Android.
You have to analyze whether a very good camera is necessary for you. I've read that the Pixels perform better than ZF. But I'm very happy with the photos that ZF9 takes.
If you can't decide, instead of spending the money on a terminal, rent it and if you like it, buy it and keep it. I did it a few years ago with a OnePlus9 Pro. I didn't know what to buy and with it I decided on my ZF9. I didn't have a good experience with the OnePlus software.
