Fairphone 2 (A9). Maximize battery life and lifespan
You want to use all the possibilities of your smartphone, but the energy lifespan of your battery is limited. Certain functions, like display brightness and data connections, drain your battery in no time. Efficient energy use helps you push those limits and extend the amount of time between charges.
Use the tips listed below to get more out of each battery charge. Not only with your Fairphone 2, but with any smartphone.
As with any smartphone, the Fairphone 2 works on a lithium-ion battery. So let us start with some general recommendations to get the most out of it.
1.1 - Battery Saver
To quickly enforce diminished battery use:
- Swipe down with one finger from the top of the screen to open the pull-down Quick settings menu and tap on the Battery Saver icon.
- If needed, tap on TURN ON. The icon should turn green.
- Additionally, quickly go to the Battery settings by tapping and holding your finger on the Battery Saver icon for a few seconds, Tap on Battery Manager and make sure it is enabled.
1.2 - Battery graph
You can see which functions use the most energy in your phone. The graph shows the pace of energy consumption. Below the graph, the functions are listed in order of most to lesser use. Tap the graph to get a more detailed graph and list.
To go to the battery graph:
- Swipe down with one finger from the top of the screen to open the pull-down Quick settings menu and tap on the Battery Saver icon and hold for a few seconds, tap the More options icon (3 vertical dots) in the top right corner, and select Battery usage
Certain tasks, such as Android OS, Android System, and Google Services are the core of the operating system. As they are essential, you can not directly optimize their battery consumption.
However, you can monitor your downloaded third-party apps that have the most impact on your battery.
- To adjust their settings: open the app and navigate to either menu or settings.
When you first start using your Fairphone, you may see drops in the battery report graph. No need for concern: your battery needs to complete a few charging cycles before it calibrates properly.
1.3 - SIM card
Make sure your SIM card is new and undamaged. An old (+1 year) or damaged SIM card makes your phones' processor work harder to keep up and can even cause serious issues.
1.4 - Temperature
Batteries need an optimum temperature to keep the chemical processes inside going. So avoid extreme heat and cold. Do not put your phone in the bright sun and keep it inside a pocket when outdoors in below zero temperatures.
2. Adjust your brightness
Your screen requires a lot of energy when in use, especially with a large, 5-inch screen. Adjust the brightness to reduce the amount of energy.
Dim the brightness level of your screen:
- Swipe down twice, with one finger from the top of the screen to open the pull-down Quick settings menu.
- Slide the little sun icon to the left to dim your display.
Access advanced brightness and sleep settings under Settings → Display.
- Turn on Adaptive brightness. This automatically adjusts the brightness on your screen to the ambient light.
- Tap Advanced → Sleep to adjust the time period for your phone to go into sleep mode. To save energy, pick a short time period like 30 seconds.
3. Adjust your connectivity settings
Data connections usually consume the most energy - apart from the display. If you use cellular data or Wi-Fi non-stop, you can drain a fully-charged battery in just a few hours. In general, it’s best to disable the connectivity functions that you do not need.
3.1 - Quick
To quickly turn them off or back on again:
- Swipe down with one finger from the top of the screen to open the pull-down Quick settings menu
- Tap the desired icon: Wi-Fi, Bluetooth, or Cellular data.
- Toggle the blue switch in the top right corner to the left to turn the connection off. The switch should turn grey.
3.2 - Advanced
Access advanced connectivity settings via Settings.
To set your data use preferences for each SIM card:
- Go to Settings → Network & internet → SIM cards to set your data use preferences for each SIM card
To let the device decide which cellular network to use based on the signal strength:
- Go to Settings → More → Cellular networks to select a SIM card. Pick 4G as the Preferred network type.
- IMPORTANT -
If you set one of the SIM cards as 3G or 4G, you MUST set the other SIM as 2G.
3.3 - Airplane mode
The best way to conserve energy without completely turning off your phone is the Airplane mode. If you can survive for a while without any data or network connections, use this.
- Swipe down with one finger from the top of the screen to open the pull-down Quick settings menu and tap on the Airplane icon.
3.4 - Extra
If you have a weak mobile or Wi-Fi signal, your phone will consume more energy to stay connected.
- Move closer to the access point or turn off the data connection if you’re not using it
- Renew your SIM card when it is older than a year or damaged
- If you spend lots of time online, you may want to install an ad blocker to reduce the amount of bandwidth and energy required to load a page.
4. Change your location settings
Location settings can also impact your battery usage. We recommend switching to a less accurate, but more battery-friendly location setting when possible.
Before you can make any changes, you need to enable Google Location Services and accept the license. To do this:
- Go to Settings → Security & location → Google Location History.
It’s important to realize that this mode reduces accuracy, so do not use this if you need very specific location information, such as directions while you are driving. You can learn more about location settings on this Google Help page.
- Go to Settings → Security & location → Google Location Accuracy and tap on the toggle to disable it (it will turn grey).
If you do not require any location services at all:
- Swipe down with one finger from the top of the screen to open the pull-down Quick settings menu and tap the Location icon.
5. Decrease the workload of your phone
Certain apps, accounts, and features impact your battery life as well. A few ways to decrease your phone’s workload include:
Wallpapers: Choose a static image instead of a dynamic one. To select a new wallpaper:
- Touch and hold a blank space on your home screen, and then tap Wallpapers at the bottom left.
Inactive apps: Uninstall apps you do not use.
- Go to Settings → Apps & notifications → See all apps, tap on the app you want to remove, and tap on UNINSTALL.
If you only see the option to DISABLE, it means that you selected a system app that cannot be removed. For some essential apps, even the option to disable will be unavailable.
Touch vibration (haptic feedback): Turn off touch vibration.
- Go to Settings → Sound & notification >→ Other sounds. Disable Vibrate on touch.
Keyboard vibration: Turn off keyboard vibration.
- Go to Settings → Language & input → Android Keyboard → Preferences and turn off Vibrate on keypress.
