Good. Now make it replaceable.
This is a great example of why mAh is a stupid metric. Double the voltage and you have the same capacity but through the power of marketing you can mislead people into thinking the battery life is increased.
The proper metric is Wh.
Absolutely agree with the fact that mAh should never have been used as a measurement of battery capacity, but increasing the voltage (while keeping the same actual capacity in Wh) makes the mAh rating lower, not higher.
1 Wh 1 V battery can provide 1 A (1000 mA) for an hour (1 V * 1 A = 1 W, 1 Wh / 1 W = 1 h) - that would be 1000 mAh.
1 Wh 2 V battery can only provide 1 A for half an hour (2 V * 1 A = 2 W, 1 Wh / 2 W = 0.5 h), and that gives you only 500 mA.
chinesium phones have 20000mAh with the same voltage as usual 5000mAh phone batteries. Wh will be better, yet now we have what we have - the same voltage batteries for most phones.
Is this not measured at a standard 3.7V for phone batteries?
Edit: In the article it’s measured at 4.53V.
Usually yes, but it doesn’t have to be.
