I’ll believe it when it ships. I’m genuinely optimistic that we can develop better batteries, but I’ve seen this story too many times before.

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.

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.

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? ;)
