Phone recommendations for light use

So I'm looking for a new phone for my dad. What would be a fast phone for non-intensive use (internet browsing, gps, emails, etc.), it doesn't require to be a powerhouse like the flagships. Removable battery would be a massive plus.
Thanks in advance!


Dreaming of Bugdroid.
Could also look at the Moto E4, about half the price of the Moto G5 and still fine for regular use.

The Moto G5 Plus and Moto E4 Plus do not have a removable battery. Standard versions of both phones do have a removable battery.
