My first Android phone was the original Motorola Droid, which I bought and loved to use despite its anti-woman marketing campaign. And one of the things that I loved was that it had an interchangeable battery. I always had an extra charged battery by hand and I simply changed it when necessary. It was much more convenient and lighter than dragging a heavy battery pack, and it kept the phone working hard during the busiest workday.
But as phone designs changed over the years, phone manufacturers abandoned interchangeable batteries to keep their phones smarter and accommodate wraparound displays. The batteries are getting stronger, but they are also making more use. Then, despite advances in energy technology, your phone may run out of power before the end of the day, especially if your device is one or two years old.
If you are experiencing that problem, you have some options. You can buy a new phone (unless you like your current phone, or if your budget is limited). You can also replace the battery, depending on the phone you have. (If you have an iPhone, it tends to be easier).
Or you can follow these tips to help you monitor and extend the use of your battery.
Understand how Doze mode works
Introduced in Android 6.0, Doze mode ensures that your phone's applications use battery power when you're not using it. There's nothing you do: Doze mode is automatically activated when your phone has been disconnected and immobile for a certain time. At that time, some applications are denied access to the network and their processing jobs are stopped, except at periodic times when they are allowed to access the network for updates and synchronizations.
In other words, when you use your phone, many of your applications will reach you until you need them again.
Now, you may not want all your applications to experience Doze Mode. If you have an application that is constantly updated for your work, you may want to continue working when you are not using the phone. This is how you do that:
- Go to your phone's settings and select "battery."
- Touch the three points in the upper right corner and select "battery usage". The following screen will show you the applications you have used since the last time you loaded your phone.
- If you are not sure whether you have activated it or not, touch any application and look for "battery optimization".
- Click on "battery optimization".
- If you see "not optimized" at the top of the screen, that means that none of your applications is optimized. Select that and click on "all applications." This will allow all your applications to use the Doze Mode.
- Then, go to your application list and choose any application you want to exempt from Doze Mode. When you see one that you want to exempt, touch the name of the application and then select "do not optimize."
Enable adaptive battery and adaptive brightness
The two battery saving functions, Adaptive Battery and Adaptive Brightness, use AI to learn how to use your applications and screen, and adjust them to suit your habits. The idea is that your applications and your screen will only extract energy from the battery when they are needed. You should have activated both by default, but it never hurts to check and make sure.
To activate the adaptive battery:
- Go to your phone's settings and select "battery."
- Search and click on "Adaptive Battery".
Something worth mentioning: although you can turn off the adaptive battery (through the same process), your phone will continue to remember what you have learned so far, and there is no way to restart the tool and start over. So, if you are experiencing problems with an application (if notifications are slow, for example) and suspect that it may be an adaptive battery that causes them (because you have "learned" something that is causing the problem), the only way to start from zero is a complete reset of your phone.
To activate the adaptive screen:
- Go to your phone's settings and select "show."
- Search and click on "Adaptive screen".
Unlike the adaptive battery, you can reset the adaptive screen so that your phone can restart the learning process. It is a series of steps a little complicated; You can get complete instructions here.
Use an application
There are several applications in Play Store that help you save battery power, and many of them are really effective. Two of the best known are AccuBattery and Greenify.
AccuBattery measures the use of your battery over time and allows you to detect any degradation. It can alert you when the battery is full, or simply let the battery charge to just under 100% (since many believe that 100% charging will accelerate the battery degradation process). It will also estimate how much time you have left, depending on how you plan to use the phone.
Meanwhile, Greenify allows you to force applications to hibernate (whether they want it or not), avoiding an unwanted battery discharge.
Deactivate unnecessary applications or uninstall them
Speaking of hibernation, nothing is lost by doing a periodic check of all the applications you have and eliminating or restricting anyone who is unnecessarily using battery power.
The first step is the simplest: check the drawer of the application and see if there is any application that does not recognize (because they have been there for a long time) or what has been tired. Why let them use the resources? Uninstall them
It is also a good idea to find out which applications are using the most power. (Note: these instructions are for a Pixel phone, your phone may work slightly differently).
- As with the previous Doze Mode, go to "settings"> "battery" and touch the "plus" symbol and the "battery usage".
- You can also touch the "plus" symbol again to select "show full use of the device", which will tell you where most of the battery's energy is being used.
If you see any application that you think is too powerful, you can prevent it from running in the background.
- In the "Use the battery" or "Show full device usage" list, tap the application that interests you.
- Look for the "background restriction". If you find it (it will not be there for all applications), touch it.
- You will receive a warning that the application may not work correctly if it can work in the background. Touch "restrict" to go ahead and prevent it from running in the background.
Use battery saving
The purpose of Battery Saver is to keep your phone running when power levels are decreasing. Prevents applications from running in the background, stops location services when the screen is off, prevents the Assistant from listening to "Hey, Google" and, otherwise, tries to make the battery last as long as possible.
You can determine that Battery Saver will activate automatically. (As always, these steps may vary depending on the phone you use).
- Go to "settings"> "battery"> "battery saver".
- Make sure that "activate automatically" is active.
- Determine what percentage you want to activate (15% is a good place to start).
If you want to enable Battery Saver manually, you can also do it here, but there is an easier and faster way. There should be a battery saving icon in the Quick Setup drop-down menu on the home screen. If you do not see it immediately, look for the "edit" pen and touch it. You can see all the icons that you can place in the Quick Settings menu; Just tap and press to move the battery saving icon up.
If things get desperate
Sometimes, with all your precautions and even with Battery Saver activated, you may find a battery almost exhausted and without immediate access to a power source. In that case, you want to keep your device turned on as long as possible so you can at least make or receive phone calls or text messages. There are several steps that can help, although some may interfere with normal use.
- Make sure all your applications are closed.
- Activate Do Not Disturb mode to stop notifications.
- Set the screen timeout for 30 seconds, so the screen will stay on if you are not using it.
- Lower the brightness of the screen as much as you can.
- Turn off Bluetooth, location tracking and Wi-Fi (unless you are actively using it). You can also use Airplane mode unless you are waiting for a phone call or a text message.
- Turn off the notification light if your phone has one.
- Turn off all the sounds and vibrations of your application.
- If your phone has an OLED screen, using dark mode can help save energy. Some phones, such as those using Samsung's One UI, have a dark mode in the whole system, so it's a good idea to check if it's available. For the rest of us, the next version of Android should also have a dark fashion throughout the system.
