83
<p class="p">Some computers appear to have a shorter battery life when running on Linux
84
than they do when running Windows or Mac OS. One reason for this is that
85
computer vendors install special software for Windows/Mac OS that optimizes
86
various hardware/software settings for a given model of computer. These tweaks
87
are often highly specific, and may not be documented, so including them in
88
Linux is difficult.</p>
89
<p class="p">Unfortunately, there is not an easy way of applying these tweaks yourself
90
without knowing exactly what they are. You may find that using some <span class="link"><a href="power-batterylife.html.en" title="Use less power and improve battery life">power-saving methods</a></span> helps, though. If your
91
computer has a <span class="link"><a href="power-batteryslow.html.en" title="Why is my laptop slow when it is on battery?">variable-speed processor</a></span>,
92
you might find that changing its settings is also useful.</p>
93
<p class="p">Another possible reason for the discrepancy is that the method of estimating
94
battery life is different on Windows/Mac OS than on Linux. The actual battery
95
life could be exactly the same, but the different methods give different
