I know there are things that won't be provided on mid level phones like the better camera, build, screen quality etc. If we focus on functionality and how many years the phone could be used for. Now some mid level phones also have 4GB RAM and 64GB storage maybe even 128GB which are plenty for most people. Regarding things like processing speed - would a newer mid level phone have something similar to a former top level phone from previous years? How many years are we talking about and could you guys give me an example.
I have read that some CPU that is in the phone some are called the high end phone chips and some are the mid level phone chips. Like the Huawei Kirin 650 series vs the 900 series.
Edit
The reason I asked is that, I had the LG G3 for 2yrs and broke so I bought a Redmi 3 and for 2yrs now I am needing to reboot the phone every few days b/c the memory runs low I think very sluggish it shows only 500-600MB free, I have the 32GB 3GB version. I guess since the LG also had 32GB I shoulda went one size up but regarding the memory. 3GB the next step is really 4GB and then it's about going to the pro versions, many standard flagship phones only have 4GB as well. I don't run that many apps, I have them installed but I really just use social media, youtube and the web browser that is all. But times it takes 8 seconds before the app starts up or swipe left of the home screen. Hence the reboots. Is going from 3GB to 4GB gonna be that big of a thing or is it the chip or is it something else ...
Cheers.
