Extend the battery life of your Fairphone 3

 

One of the features of Android 9 is that it has adaptive battery software to increase battery life. Apart from that, your Fairphone 3 comes with a battery that will hold quite some charge for long (3060mAh /  3.85 V).

Still, the energy lifespan of your battery is limited. So to use all of the possibilities of your smartphone, we have some tips for you to make the most out of the battery charge. Certain functions, like display brightness and data connections, drain any 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 3, but with any smartphone.

 

1. General

As with any smartphone, the Fairphone 3 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:

  1. Swipe down with two fingers from the top of the screen to open the pull-down Quick settings menu and tap on Battery Saver / the Battery icon
  2. Confirm that you want to turn on Battery Saver by clicking Turn On
  3. When Battery Saver is on:
    1. Visually: the Battery icon in Quick settings turns green, the Quick Settings menu itself turns black, the battery icon in the top bar shows an orange outline and the brightness of the display turns down.
    2. In the background: less data are used (so you will get less updates) as apps are allowed to update data at a lower rate. Location sharing shall also be minimized, so you might get a less accurate navigation experience. 

 

1.2 - Battery graph

You can see yourself 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 menu to get a more detailed graph and list.

To go to the battery graph:

  1.  Go to SettingsBattery → tap the Menu (three vertically aligned dots on top left) → Battery usage to see a graph of your battery use split by tasks.
  2. Tap again on the Menu dots to Show full device usage: that displays historical details and specifics.

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 3, 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.

To go quickly to the battery graph:

  • Swipe down with two fingers from the top of the screen to open the pull-down Quick settings menu and push and hold the Battery icon. Tap on the Menu dots on top right to open Battery usage. Tap the Menu dots again to get a more detailed graph and detailed information. 

 

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:

  1. Swipe down with two fingers from the top of the screen to open the pull-down Quick settings menu
  2. 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 - especially on the go - , 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:

  1. Swipe down with two fingers from the top of the screen to open the pull-down Quick settings menu
  2. Tap the desired icon: Wi-Fi, Bluetooth or Mobile data.
  3. Toggle the green 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 → Mobile network → select the SIM card tab (the tab shows the name of the operator of your SIM card) → Data usage 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 Network & internet → SIM cards to select a SIM card. Pick 4G as the Preferred network type.

3.3 - Airplane mode

The best way to conserve energy without completely turning off your phone, is Airplane mode. If you can survive for a while without any data, calls or network connections, use this.

  • Swipe down with two fingers 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 to switch to a less accurate, but more battery-friendly location setting when possible.

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 SettingsLocationMode and select Battery saving.
  • A method where you can decide which location settings to use is to go to Settings Security & Location → open Advanced → Location. Tap on Location to open the Use location menu. Switch the toggle on top right to Off.

If you do not require any location services at all:

  • Swipe down with two fingers from the top of the screen to open the pull-down Quick settings menu and tap the Location icon. (If it doesn't show, you can edit the Quick settings menu - tap the pencil icon - to add it)

 

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.

Inactive apps: Deactivate or Uninstall apps you do not use.

  • Deactivate: tap the (square) button on your display to show all active apps and functions. Swipe up to deactivate them.
  • Uninstall: go to All Apps, hold down the app you want to remove and slide it to Uninstall at the top of the screen and release your finger.

Accounts: You can remove online accounts that you do not use.

  • Go to Settings Accounts. Locate the account you want to remove. Tap on the account to see the button Remove account.

Users: Remove unnecessary users. The Guest account cannot be removed.

  • Go to Settings System → open Advanced → Multiple users. Tap on the cogwheel icon next to the user profile that you want to remove. Tap Remove user.

Touch vibration (haptic feedback): Turn off touch vibration.

  • Go to SettingsSound → open Advanced. Switch the Touch vibration toggle to Off to disable it.  

Sounds: Turn off sounds like dial pad tones, touch or charging sounds.

  • Go to SettingsSound → open Advanced. Switch the toggle to Off to disable the function.  

Keyboard vibration: Turn off keyboard vibration.

  • Go to Settings  System Language & input Virtual keyboard → tap on the keyboard of your choice to open up Preferences and switch the toggle to turn off Haptic feedback on keypress.

All these tips should grant you the most of the battery life of your Fairphone 3!
