Hacks To Save Battery Life
Hacks To Save Battery Life

Smartphones, no matter how advanced the technology, still have a very serious problem, autonomy. The research on battery technologies is going baby steps while the rest of the features go by leaps and bounds. To alleviate this problem, manufacturers have to choose to optimize the use of their mobile’s battery.

Fast charging and energy saving mode are the methods used so that we do not get stuck at the first moment of change. But it is us, the users, who have to do more work on a daily basis to save battery, and for those who do not know very well how to gain autonomy are these simple tips.

Below are some hacks to save battery life of your smartphone:

1. Use the right screen brightness

The screen is the element that more battery spends on any smartphone, whether small or large, with HD or QHD resolution, is the component that consumes the most energy. The miraculous option of calibrating the brightness to your liking can give you a few precious minutes of use of your terminal.

Always use the right brightness so you can see the screen well but without setting it too high. Normally, in low light conditions, it is sufficient to put it to the minimum or, if it is too low, to 20% or 25%, it is not necessary anymore. Also, in these conditions, not having the brightness too high is good for your eyesight.

Where more care should be taken is in very bright conditions (under the sun, for example), because you need to put the high brightness to see the content, so you spend more battery, so, to minimize this expense as much as possible, calibrate it enough so that you can see the screen and, at the same time, not spend too much battery.

The automatic brightness in many occasions is a good solution, and very comfortable, so as not to have to calibrate by hand, but I still recommend doing it manually if it does not work very well. In addition, the automatic brightness tends to put more brightness in good lighting conditions.


2. Activate the connections when you need them and deactivate them when you stop using them

Although silently, the connections of our devices are also spending energy, especially some like Bluetooth. With such complete devices as smartphones, the different ways to connect us make life easier, from connecting to the Internet in the middle of the street to transfer files to another device.

Do not leave all your phone connections enabled at all times, especially if you are not going to need them. A habit that I have taken for quite some time is that of, when I leave home, I turn off Wi-Fi and activate data and when I go back I do the opposite. Do not leave the Wi-Fi activated if you are not going to use it to gain accuracy in the location.

Speaking of the location, you may want to leave it activated at all times, but if you are going to do it, go to Settings> Location and change the mode to Battery saving (you also access this menu by pressing the Location icon on the bar Quick settings) and use High precision mode only if you are going to use navigation (Google Maps or similar).

As for the other connections (Bluetooth, Wi-Fi, etc.) more of the same, do not leave them activated if you are not going to use them, this will affect both the battery life day by day and the life of the battery. same You may have to invest a few seconds in activating or deactivating the connections, but in return you can earn several minutes of screen.


3. Do not “kill” background applications that you use frequently

In our smartphones there are installed applications that we use frequently, some that we use in certain situations and others that we do not use but that are installed there by the will of the manufacturer. Android has an effective way that we can access our recently used applications without spending too much battery.

To summarize, when we leave an app to access another or to go to the main screen, Android tries, as much as possible (because it depends on RAM), to keep it open, so that when we access it again it will open much more quickly. This not only saves us time, but also battery.

When an application has to be executed from scratch, the responsible components have to make an extra effort, which does not happen if you have left it open in the background, with which the energy expenditure is lower. Yes, the number of apps that can be active and the speed at which it is accessed depends on the RAM (today, with between 4 and 8 GB this problem is almost anecdotal).

The more RAM the device has, the more applications you can leave “open”, and the more advanced, the faster you can access those applications. Therefore, if you use an application frequently, do not “kill” it in the screen of recent apps and close only those that you are not going to use in a long time.


4. Be careful with the applications you install on your device

Not everything is open and close applications, there are some that just install them and you are condemning to suffer with the autonomy of your mobile. It is true that all applications spend battery (missing more), but the case of some (suspicion look to Facebook) have a higher battery than what should have an application of its kind.

I mentioned Facebook because it is one of the first we have all thought about (personally, I have the uninstalled app, I prefer to use the web version), but it is not the only one. Do you know the well-known and less-loved Clean Master? Yes, that application that “cleans” the RAM to make your mobile faster.

In that specific case, Clean Master spends more battery because what it does is “kill” the processes in the background (see the previous point), with the consequent additional cost of battery, and that without counting its advertising so invasive that it interferes the experience of use. But applications that spend battery by hobby there are many more than these two.

Therefore, the advice we give you is to be very careful with the applications that you install on your phone, as they could condemn your battery to not reach the end of the day. If that application is essential, you may be able to access a web version (in the case of social networks) or look for an alternative app on Google Play that is lighter and offers the same (or more).


5. Do not turn on the screen more than necessary or leave it activated too long

Continuously we are turning on the screen, either to perform certain tasks or to check the time and arrival of notifications. Although Always On screens are a good solution, not everyone has them, so we’ll have to control ourselves how often we turn it on so we do not spend more battery than necessary.

Even more important is the time that we keep the screen on, and it is our responsibility to regulate that time either manually (turning it off when we stop using the phone) or automatically (setting the time that the screen will be on without let’s use)

If you choose to configure the automatic screen shutdown, configuring it to turn off after 15 or 30 seconds is sufficient. In addition, we avoid any problem that the screen may have with the passage of time or, in the worst case, delay it as much as possible. And your battery will thank you!


These have been some of the most effective hacks to save battery life of your mobile, most of them known. But you may want to help someone known about this problem, or be new to Android and do not know how to maximize the autonomy of your device inside As much as possible. We hope you find these tips useful.
