It looks wierd when you change dpi. I dont like 392 as everything looks big, i use 450(which is 449) and screen is sharp, everything is not so small but normal for a screen that is big(mix 2) and the battery icon is also like the one in his screenshot. I use percentage in icon for now.
Thanks for this awesome tip.
Shame on me, I've never tried to change the dpi before.
Anyway, I can confirm the charging icon of my Whyred is the same than yours with 449 as dpi.
