      I had an Oukitel that I ran for almost 4 weeks. Had to charge it for a trip off grid. Talk about chunky!

      Might buy another model, but had to drop Verizon to get it working and T-Mobile took a week to figure out how to activate it. PITA, but it was solid once working. Great BT speaker, couldn’t kill the battery, everything worked great. Carrying the thing was a pain, even with a pack. Not sure I want all that mass again.

      If you want a phone you can beat a man to death with, Oukitel it is!

        Uhm IIRC typical battery is 2000 mAh/day, so one week battery is 14 Ah/day, which is 50 Wh assuming 3.7 V.

        A typical sodium ion battery (which i very much like btw) typically holds 0.2 kWh/kg, so 200 Wh/kg, so to store 50 Wh, you’d need around 250g of battery.

        For reference, i think smartphones should be about as heavy as an apple (fruit) which is 100g average. And the battery makes most of that weight (like, 80%). So the battery could be about 80g, which would store 16 Wh of energy. That would make about 4000 mAh. Which is what many phones today already have. Which lasts for 1-2 days.

          Okay but the iPhone air is 165 grams with a 3036 mah battery, so what are you gonna remove to make it 100g?

        I have a motog5 if I load a non google OS like lineageOS, or use Googles Android with a TrackerControl app that let’s you turn off app tracking, then I would get 3 days between charge, with regular use. A few weeks if it was just standby for phonecalls
