FP4. Maximize battery lifespan

 

Fairphone 4 (FP4), like most modern smartphones, comes with a lithium-ion battery.
However, unlike most modern smartphones, your Fairphone 4 has a removable battery!

The Fairphone 4 battery holds a typical capacity of 3905 mAh. This should be more than enough to last you through the day. Regardless of how big a battery is, some settings will drain the battery very fast. 

Modern lithium batteries are capable of holding the charge for an extended period. Still, the lifespan of your battery is limited. Efficient energy use helps extend the amount of time between charges. You can use the tips listed below to get more out of each battery charge and maximize your battery life.

 

1. General

Let us start with some general recommendations.

 

1.1 - Always update to the latest software

 

Software updates often include bug fixes, which let you save energy. We recommend you to follow our article and continually update your Fairphone 4 to the latest Fairphone OS.

 

1.2 - Avoid extreme temperatures

 

Batteries need an optimum temperature to keep the chemical processes inside going. So avoid extreme heat and cold. Do not put your phone in direct sunlight when warm, or close to a radiator. If the temperatures are below zero degrees, keep it inside a pocket when outdoors.

 

1.3 - SIM card

 

Make sure your SIM card is newer than 2 years and undamaged. An old or damaged SIM card makes your phones' processor work harder to keep up and can even cause serious issues.

 

1.4 - Long time storing

 

If your battery/device is fully discharged for a long time, it may require up to 20 minutes of charging before you can notice any difference. Even more, if you have a weak charger. If you do not see any change after a couple of hours, the battery might not work anymore.

 

If you store your battery/device for an extended period, keep it at room temperature (see above point 1.2 - Avoid extreme temperatures), and make sure to charge your battery between 50% and 80% every couple of months.

A fully discharged battery could fall into an over-discharged state. This will severely diminish its capacity to hold a charge. In the same way, charging a battery that you do not use for a prolonged time, for 100% too often, will also shorten battery life.

 

2. Optimize your settings

You can use the Quick settings menu to enable or disable some power-consuming features quickly.

The Quick settings menu might have several pages, swipe right to see more icons.

You can also edit the Quick settings menu to add or remove icons. To do so:

  1. Swipe down twice, with one finger, from the top of the screen. You will open the pull-down Quick settings menu.
  2. Tap the Pencil icon Edit_icon.png in the central left corner.
  3. Hold and drag the tiles. Bottom to the top to add them to the menu, and top to bottom to remove them.

 

2.1 - Display settings

Your screen requires a lot of energy when in use. By adjusting some settings, you can significantly extend your battery life.

 

2.1.1 - Adjust your brightness

Fairphone 4 has an Adaptive brightness feature. It will optimize the brightness of the screen according to your activities and your environment.

  • To enable the advanced brightness, go to Settings Display → and turn on Adaptive brightness.

You can also dim the brightness level of your screen manually. To do so:

  1. Swipe down, twice, with a finger from the top of the screen. You will open the pull-down Quick settings menu.
  2. To dim your display, slide the little Sun icon to the left. The A icon next to it is a shortcut to enable or disable the Adaptive brightness.

 

2.1.1 - Adjust your screen timeout

To save energy, you can also shorten your Screen timeout. If you set a Screen lock, a shorter interval will also increase the security of your device if you leave it unattended.

  • To adjust the interval, go to Settings Display → Advanced → Screen Timeout. For a good balance, we advise you to select "30 seconds". 

 

2.2 - Connection settings

Data connections also use lots of energy. Especially when on the go, it’s advisable to disable the connectivity functions you do not need, such as Wi-Fi when outdoors. If you don't, your phone will constantly seek Wi-Fi networks to connect.

 

2.2.1 - Wi-Fi, Mobile data, Bluetooth

  1. Swipe down, twice, with a finger from the top of the screen. You will open the pull-down Quick settings menu.
  2. Tap the desired icon: Wi-Fi Wifi.png , Mobile dataMobile_data.png, or Bluetooth Bluetooth_icon.png .

- IMPORTANT -
Be aware that most of the Coronavirus monitoring apps require Bluetooth to be enabled.

 

2.2.2 - Location service

The Location service can also impact your battery usage. When you don't need it, you can disable it using the quick settings menu.

  1. Swipe down, twice, with a finger from the top of the screen. You will open the pull-down Quick settings menu.
  2. Tap the Location icon to enable or disable it. You might need to add the shortcut by tapping on the Pencil icon (as we explained previously in this article).

- IMPORTANT -
Some apps or services need to know your position to work. Examples are navigation apps, delivery apps, vehicle sharing apps, geotagging apps, etc.

 

2.2.3 - Airplane mode

An effective way to conserve energy without completely turning off your phone is via Airplane mode. If you can spend some time without any connectivity, you use this.

  1. Swipe down, twice, with a finger from the top of the screen. You will open the pull-down Quick settings menu.
  2. Tap on the Airplane mode iconAirplane_mode.png.

 

Extras

  • If your mobile signal or Wi-Fi is weak, your phone will consume more energy to stay connected. Move where you have a better signal. If you’re not using it, turn off the data connection. 
  • Your SIM card can cause issues. Make sure it is newer than 2 years and undamaged.
  • If you spend lots of time online, you may want to install an ad blocker to reduce the bandwidth and energy required to load a page.

 

2.4 Battery settings

 

2.4.1 - Battery usage

You can see the details of what uses the most energy in your phone. The battery graph shows the pace of energy consumption. Below the graph, the system lists your applications in order of use.

To see the details:

  1.  Go to SettingsBattery → tap the Additional option menu (three vertically aligned dots on the top left corner) → Battery usage to see a graph of your battery usage and the list of the most power-draining apps.
