I'm wondering whether it is now time for regulators to pressure mobile phone companies to install longer life batteries. There is not really an incentive to prolong device life for manufacturers and when I look at recent progress on the car industry and utility battery side there is imho. potential.
This regulation seems to relax the rules a bit for batteries that last longer.
I wonder if it will just lead to using same size batteries more gently.
Batteries always have a limited lifetime.
"back in the day" we had waterproof phones with user replacable batteries, you could just buy another battery and replace it yourself. I have no idea why we can't do this now.
Are there battery chemistries available which would allow for significantly longer life without sacrificing cost, power capacity, size, or safety? Generally the best way to prolong battery life is for the consumer to never fully charge or discharge.
