How much power does an 8A battery have

Power Capacity and Power Capability | All About Batteries

Power capacity is how much energy is stored in the battery. This power is often expressed in Watt-hours (the symbol Wh ). A Watt-hour is the voltage (V) that the battery provides multiplied by how much current (Amps) the battery can provide for some amount of time (generally in hours).

How much battery does the Google Pixel 8A have?

The Pixel 8a is powered by a 4,492mAh battery, a hair smaller capacity than the Pixel 8's 4,575mAh cell. It also features a whisker tinier display with a 6.1-inch diagonal instead of 6.2". And that is why it was no surprise the Pixel 8a scored a similar Active Use Score as the OG Pixel 8 - 11 hours and 25 minutes.

How is power capacity measured in a 2Ah battery?

The way the power capability is measured is in C 's. A C is the Amp-hour capacity divided by 1 hour. So the C of a 2Ah battery is 2A. The amount of current a battery 'likes' to have drawn from it is measured in C. The higher the C the more current you can draw from the battery without exhausting it prematurely.

What's the difference between Google Pixel 8 & 8A?

The Google Pixel 8a has a lightly smaller OLED screen compared to the Pixel 8 - it's a 6.1-inch OLED of 1,080 x 2,400 pixels.
