Battery Life Question

I currently only use PostmarketOS on my Pinephone CE and PineTab. On the Pinephone CE I find I can sometimes go from a full charge to 50% or less within 4-5 hours which is keeping it from being my daily driver. I know this is still being worked on but for anyone who has used PostmarketOS on other devices, is there a phone you could recommend that would give me about 11 hours of life between charges ? My main uses are FluffyChat; Tootle and light web browsing ? I usually use Phosh if that matters.
