How to Turn on Survival Mode on Your Android Phone to Get the Most Out of the Final 1% of Battery Life
Background apps, games, and media playback are some of the processes that consume the most battery power on an Android phone, but nothing consumes more battery power than the screen brightness. It is always active, and lighting it up requires a lot of power.
Although all smartphones offer options to adjust brightness, the system sets a minimum that is not always enough if you are looking to maximize battery life, especially when there is only 1% left.
A trick to reduce the brightness of the mobile screen to the minimum
When your phone's battery is at its lowest, you can resort to a very effective trick to activate the phone's extreme survival mode, which involves reducing the screen brightness to below the pre-set limits on your phone.
Google's operating system doesn't have a feature to implement this configuration, so you need to use an app like Halo, which allows you to apply filters and dim the screen beyond what Android allows by default.
Not only is it useful for saving battery, it also improves the viewing experience in dark environments, where even the lowest level of brightness can be annoying. If you have an Android phone and want to maximize battery life, here we will show you how to configure it in minutes.
The first step is to download Halo from the Google Play Store on your Android phone. It's free.
Once installed, open it and click OK when prompted; these permissions are necessary for it to work.
Next, you will be asked to enable the option to display over other apps by sliding the switch. This is necessary so that Halo can apply filters and thus reduce the screen brightness to the minimum possible.
From the main menu of the app, select Night Mode and adjust the brightness intensity to your preference. The darker the color, the less power consumption.
This way, you can maximize your battery life, making that last 1% last long enough to make that last important call or send an emergency message on WhatsApp.
It is worth noting that every Android phone has a limit for reducing the screen brightness, and by default, the system does not allow it to be reduced below certain fixed values. If your battery is weak, you can apply this trick and benefit from it.
