The screen quality is excellent. Not sharp as the 3 XL but sharp enough for my eyes. I've used the smaller 3 until yesterday and of course the 3a XL is bigger. But the more on battery is it worth for me. The lack of some features is not that notable in day to day use. The speaker are better then...
I've been using the 3a XL since yesterday and the battery lifeks amazing so far. Using the typical casual stuff like social media and web browsing i can squeeze out 8 to 9 hours SoT on mobile data with a weak signal. The performance of the system is great
I have about 8 hours in WiFi and 6h on 4G. I'm a heavy user. The features are great ( 3 finger screenshot, Moto Key, Bluetooth 5.0 etc. ) More worth the money then the Z2 play or the Z2 Force
