Enable/disable Motion and Fitness Tracking on your iPhone
Fitness tracking is a great thing, as it brings additional attention to often neglected parts of our life, such as our sedentary and inactive lifestyles. By tracking your every movement via the motion tracker in the iPhone, the Health application can present you with details about the amount of activity in your daily routine.
If you use an external fitness tracker or don’t want to use these types of features at all, you may disable the motion and fitness tracking for purposes of battery life improvement and conservation. This is a guide on how to completely disable fitness tracking on iPhone.
If left at the default settings, your iPhone will continuously check for motion and use a little (probably negligible) bit of energy in the process of doing so. Only the iPhone 5s and above (so including the iPhone 6, iPhone 6 Plus and the as of yet unreleased 6s models) track your motion continuously and use the sensors for fitness purposes. Earlier models only use the sensors when activated specifically, e.g. by apps that track you while jogging or running. You can customize and disable the tracking of your fitness and motion data, if desired.
How to disable or enable the motion and fitness tracking on iPhone
Go to your “Settings” app and head over to the “Privacy” section by scrolling down a bit. Now scroll down again and tap “Motion & Fitness”. Then disable the “Fitness Tracking” toggle to turn off the tracking feature altogether. Note that you won’t have any kind of step counting or other sensory data in the Health app. You may also restrict the tracking to certain apps by only disabling some of the entries, such as the “Health” or “Activity” application, or another app you suspect might be eating up your battery.
