For those that complain all the time about the lack of LARGE LITHIUM batteries in our phones in the US, this is for you !

There are rules in this country about how many watt hours and the capacity of the mAh limit that batteries can have to be transported from overseas into this country without them changing the classification to what is called dangerous goods. Dangerous goods significantly incur larger shipping fees to be brought into the US, and transported throughout the US.

In the US single cell lithium batteries are capped at just under 5200 mAh, and has to be under 20 Watt hours ( how much power a battery used in 1 hour) Samsung's 5000 mAh battery is rated at 19.85 Watt hours just a hair under the limit. All lithium batteries in cell phones have to be submitted to the FCC for testing for rating (publicly available, it's how leakers get their info on upcoming phone releases)

Write to your US rep to have the antiquated regulations revised for modern tech and improved safety of newer lithium batteries.

Please don't came back with, but, One+13 has a 6000 mAh battery, it doesn't it is dual cell . It has 2 3000 mAh batteries so it could be sold in the US and EU. The EU it is capped at 5600 mAh ( couldn't find info on Watt Hours) Edit: One Plus uses Silicon Carbon batteries!

BTW, Samsung's 5000 mAh has been rated for 2000 charging cycles before the battery health will reach 80%. Those new 6000 mAh batteries that TechTubers have been raving about, they have been rated for 1500 charging cycles before reaching 80 battery health due to faster charging rates. 

Ps, another tidbit.
Before you ask then why doesn't Samsung just put a 5200 mAh battery in the Ultra. Good question, during the manufacturing of lithium ion batteries mAh can fluctuate between each battery produced, this is why in the battery section of about phone it will say typical, 5000 mAh, it could be as much as 150mAh higher or lower. Samsung has to insure that it doesn't go over 5200 mAh.

Fine, but what am I supposed to be looking at in that link. It's a home page pointing to product types.

What point is being made regarding EU standards and looking up products. The topic OP is about about battery power capacity limitation in the US. My initai response regards using S/C batteries as they are as I described which would make them more efficient over what is near universally used here in L-ion types.

Also, looked at other comments in other topics either started or with replies under your name and they all have "Honored Contributor" next to your name.

When someone creates a post it will say writer for that post. This way in subsequent comments you know who the original poster of that topic is.

You were questioning @TipsyTrex sources, I provided a source to let you look up charging cycles of phones. A determining factor in longevity of batteries. All Samsung phone have the longest amount of charging cycles before battery health goes below 80%. The industry standard for when batteries should be replaced.

Those sources you provided di not cover what tipsy stated. His post was was anti-(insert nation or non-US related products). Tipsy can do that themself.

Part of what he stated is that they degrade faster. I provided proof that part of what he said is true.

No more, no less

Post that directly and while doing that, note that the Oneplus 13 uses silicon carbon batteries.

I edited the post to denote that One+ is using SiC batteries ! Which was pertinent to the post. The post started off on WHY THEY DONT USE LARGER BATTERIES!

It then devolved into this back and forth

Go to cellphones and tablets and check for charging cycles. They are all there!

You asked for source material
