- Dim the screenLighting up the screen is one of the big power consumers. This is one place to conserve a lot of battery capacity. Although you may have an automatic display brightness control, it is still a good idea to adjust brightness manually. Displays are often much brighter than needed and you can really add to the battery life by using only as much brightness as needed.
- Turn off the vibratorOf course, if you are in a big meeting and expecting an important call you’ll leave it on. But often, there is no real need for it.
- Turn off BluetoothUnless you are connecting to other devices, there is no need for this
- Only use 4G/LTE connections when you need to4G /LTE radios are voracious consumers of power. If you can use a Wi-Fi hotspot, save energy (and maybe money) by turning your data connection off.
- Turn off Wi-Fi when not in useThis is the converse of tip number 4. If you are not using a hot-spot to connect, there is no need to have the Wi-Fi connection running
- Limit use of GPS location servicesShut off Notifications, or limit the number of apps that can use your location to those that really need it. A lot of apps constantly checking your location can be a power drain (not to mention a privacy problem)
- Check for email manually (Push)Instead of automatically checking every 15 minutes or whatever interval is normally set, check your email yourself (but not too often)
- Turn off apps running in backgroundIt’s easy to end up with a host of apps running in the background. Not only do they consume power but they can use enough memory to slow down your device. Turn them off when you are finished.
