Also need replaceable batteries or atleast some standardized Li-Ion flat packs
Then we can stop tossing entire phones in the garbage.
I have a Pixel 5. The Pixel 7 isn't even an improvement to me. The fact that my battery is at 15% after the day is done means I am on my last year with the device.
I have a Nexus 6 with basically no battery to speak of but it works great still outside of that.
So for my second suggestion, if a company claims to be focused on climate change reduction, using a non-removable battery will double the tax.
All proceeds go to renewables for whatever state has the best(lowest) carbon footprint not yet at 0.
Let's see how long the "thinness" of the phone matters.
