  Once a week for the last 10 years a breakthrough is announced and twice on a full moon.

  Every “breakthrough” makes batteries a percentage point better though.

    According to the graphic though, this one’s at 99%, so… Next week? ;)

  Batteries have been getting better. Density has increased by more than 8 times since 2008: energy.gov/…/fotw-1234-april-18-2022-volumetric-e…

    A cool thing to do is to go on a site like GSMArena and follow the battery capacity over time of a particular line of phone (you can adjust for phone weight and volume if you want). It’ll steadily go up.

    In 2010 most phone batteries were 1000-1500mAh. Even something like 2000mAh was a huge battery.

    In 2015, phone batteries were up to 2500-3000mAh.

    In 2020, they were up to 4000-4500mAh. 5000mAh was considered a big battery.

    Now, we are commonly seeing 5000-5500mAh batteries in mainstream phones, enabling most phones to get 12-14 hours of battery life (when new).

    That’s really cool and more impressive than I would have guessed. Thanks.

  Those 90 stories you’ve seen generally did all ship.

  Same here. I’m not clicking on the article. I’ll celebrate when a retail product comes out with said battery.

  Feels like I’ve seen the same story in the last 20 years.

  Remember fuel cells? One tiny drop would power your phone for a week.

  Battery news is pretty world changing so I understand whybit gets the same kind of attention miracle health advancements get. Unfortunately the hardest part remains making a commercially viable product but that said even finding new techniques that may not make it to market still advance the field further and expand our understanding.
