We have already started talking about the issues occurring in mobile device. This time we are going to focus on the problems connected to their displays, location detection and wireless connection.
Display
One of the biggest draining factors goes to the display and how long the display is turned on. Although the amount of usage depends on how big the display is and what kind of display it is, they do drain the battery. Always try to lock the screen when you are not using the display, hoping locking will turn off the display, which is typical behaviour of modern mobile devices. Also, you want to keep the brightness as low as possible from the settings. The device may look so good on full brightness but this drains the battery more than usual. You set the brightness to auto-adjustment or set the brightness manually. In case if you find yourself always leaving the brightness manually to full, you might want to compromise by setting the display to auto-adjustment for brightness.
You should find the battery usage and monitor inside any of the settings. Go there and look for battery stat, you will find most of the battery is used heavily by the screen alone.
How many options you have to optimize the display depends on the make and model of the manufacturer. You can generally control how long the screen stays up after your last input, and if the screen should wake up, or stay up after receiving a notification. Most devices now have power-saving modes that quickly optimize your device for the best power efficiency. There is also grayscale power saving which displays grayscale instead of full colour. OLED display type uses less power to properly display dark colours. Should your device has an OLED panel, you can reduce the power consumption by using black wallpaper and configuring apps to use a dark theme if there is an option. This is a trick that can save you on any battery-driven mobile device.
Wireless Communication
This is a nifty and must-have feature that makes the smartphone so demanding and this is also one of the largest battery draining factors.
Note that any wireless communication like cellular data, Wi-Fi, Bluetooth, NFC, etc. Corresponds to the radio inside the device. To use such a communication method, the radio needs enough power. If you are not really using any of the communication modes mentioned or more than this, and the radio is on, you are wasting a large amount of power and resources.
How much power this communication technology draws varies under different circumstances, but keep these two guidelines under the sleeve. Searching for the signal is quite power-consuming and the apps inside the device will do more work in the background when the connections are available.
When you are traveling outside the regularly populated area, your device uses a lot of power to talk to distant towers and stations. This apparently drains quite a lot of power.
Location
This is used to give you the optimal experience you need for some apps. Such as google maps and food delivery apps. With the location on, people like the food delivery guy can track you and able to deliver the food. This is useful in a lot of cases, for instance, if the device is lost, you can track it down based on the location but this tremendously drains battery power. You can still use a low-power location tracker like over Wi-Fi networks or cellular but GPS provides high accuracy.
The optimal solution is to, keep your location turned off when you do not need them. There is another solution is, you can turn off the location service per app based. If an app needs your location data to function properly, it will prompt you with the message to turn on the location service.
Apps which do not necessarily need updated location data may be less demanding and stale data is enough. The thing is if you should or should not turn off the location service, depends solely on how much you use the apps that require the precise location. These are the cases you might want to keep in mind to optimize and troubleshoot your mobile devices.
