It wasn&#x27;t intended to be an excuse for not using &quot;correct&quot; terminology or units.<p>The reason that these terminology and units were used by OP was because at a fixed voltage it is common for engineers to think about current instead of watts... even when their aiming to reduce power.<p>I&#x27;m not sure of the exact reason for this, but I suspect that it&#x27;s because:<p>a) Measuring current is a more fundamental function of instruments. Quite a lot don&#x27;t even measure power. So talking about current instead of power, even when you&#x27;re aim is to reduce power, makes for a smoother process from a practical sense.<p>b) Batteries are usually measured in mAh. At lower power&#x2F;currents you&#x27;re usually using a linear regulator and therefore dividing mAh by mA is a very important measure. So you often keep everything in mA.
