Completely empty parrot championships. Now more important is high-quality strapping for modern SoCs. A smartphone in 2023 MUST have 4k@60fps video recording with OIS, a notification light (with a high contrast IPS matrix, which is good instead of a flickering AMOLED) and have other important elements like an audio jack for high-quality wired headphones, a video output (which is built into the 100% Medaitek / Qualcomm SoC) display port not lower than dp1.4b, so that you can turn a modern smartphone into a portable workplace with a monitor, keyboard and mouse via an externally powered usb-c hub. But in most models, none of this is. Therefore, most modern smartphones are technological garbage.
And most importantly, stupid or intentionally doing this, manufacturers of all smartphones should stop the criminal practice of using the battery charging mode, in which even a slight deviation of the charge from 100% again leads to recharging the battery, thereby all of them deliberately remove the possibility of using a smartphone 100% of the time connected to charging, like laptops, where there are special charging modes to conserve battery that exclude recharging the battery, at least until the charge drops below 95% or in the form of user-configurable thresholds, as in normal business models. This makes it impossible to use smartphones without wasting battery life on constant recharging and without worrying about the operating time when they work as a laptop or sound player for an external DAC with amplifier, etc. stationary applications.
