Laptops predate cell phones in mainstream use. When laptops started, there were a variety of battery types in use with no standard charging voltage so Wh was the fair way to compare.
Cell phones have pretty much always been 3.7v lithium so mAh is a fair comparison and gives a bigger number than Wh.
I think you misunderstand nominal voltage and fully charged voltage. 3.7v is the nominal voltage for a lipo battery. 4.2v is the standard fully charged voltage. However, phone batteries are rated at 4.3v.
3000 mAh * 3.7V = 11.100 mWh
Much bigger. Much better.
I hate mAh… it’s absolutely no information how much energy is inside without taking the voltage into account. If you use directly (m)Wh, you directly have the amount of energy the battery can contain.

More like 4-4.4v when fully charged. They should actually list the voltage as well as it affects longetivity
Eidt: voltage
Most phone batteries are rated for 4.3v
Most people have low end phones though.
And those are rated around 3.7v

You could just put it in mWh. BAM, bigger number.
