There's a reason your Galaxy phone battery capacity isn't bigger
cross-posted from: https://lemmy.world/post/32467417
Anti-clickbait title: the US federal regulation limiting cell phone battery capacity.
If you want to skip the click through: 20Wh maximum

Thanks for this. Another important bit:
5,000mAh × 3.88V ÷ 1,000 ≈ 19.4Wh
The difference between cells and batteries is that you have to have multiple lithium cells to make a battery.
Edit: this is around 25000 mAh
What's the reasoning behind this? Less risk of explosion?
Effectively. Transportation safety with exemptions made for batteries under 20Wh.

If you read the article or regulation, you'll note that there are some ways to get around this by dividing the battery into cells.
Also, that is a fucking hilarious "phone."
