If you have Pinephone Keyboard then Leste would be better with Pinephone. You Battery life is enough if you remember charge everynight and if it is heavy in use (streaming videos) over 8 hours in day, you should little charge when you take brake. And you have to take brake even you charge all time, because with Pinephone Keyboard charging speed from Keyboard side battery to Pinephone side battery is little slower than what "heaviest use" uses battery.

All though Leste is quite good with Pinephone, there is some things that can go better, example changing phone call volume during call you have to use Pulse Audio Volume Control. SMS messages works, but MMS not. How about Mobian those things?
