+### 4.xi. Will this plugin eat all of my laptop battery power?
+
+ALE takes advantage of the power of various tools to check your code. This of
+course means that CPU time will be used to continuously check your code. If you
+are concerned about the CPU time ALE will spend, which will of course imply
+some cost to battery life, you can adjust your settings to make your CPU do
+less work.
+
+First, consider increasing the delay before which ALE will run any linters
+while you type. ALE uses a timeout which is cancelled and reset every time you
+type, and this delay can be increased so linters are run less often. See
+`:help g:ale_lint_delay` for more information.
+
+If you don't wish to run linters while you type, you can disable that
+behaviour. Set `g:ale_lint_on_text_changed` to `0`, and consider setting
+`g:ale_lint_on_save` to `1` to enable linting when you save files. You won't
+get as frequent error checking, but ALE shouldn't block your ability to edit a
+document after you save a file, so the asynchronous nature of the plugin will
+still be an advantage.
+
+If you are still concerned, you can turn the automatic linting off altogether,
+including the option `g:ale_lint_on_enter`, and you can run ALE manually with
+`:call ale#Lint()`.
