Finally new ARM cores from A78 (2020) to A720 (2023). Let's hope it won't take long till A725 (2024), which seems to have major improvements:

Quoteits software support has been extended to six years (until 03/31/2032), which includes security patches as well as OS upgrades
My OnePlus 7 (LineageOS, Android 15) still runs all apps just fine (I don't game at all on my smartphone, so maybe/probably its GPU wouldn't be fast enough for the latest AAA games' graphics), so the software support, at least for the security updates, should be extended still, from 6 years to 7-8.
The battery test results seem suspect. They are significantly higher than results from other sites, and even higher than the Oppo Find X9 Pro H.264 test (41.8h vs 41.2h) when it has a 5000mAh vs 7500mAh battery.
