The Power-Saving Benefits of Airplane Mode
Enabling airplane mode on
your device can significantly save battery life by disabling several
power-hungry features and functions.
1. Cellular Connectivity
Searching for Signals
Battery Drain: As your phone keeps searching for the strongest cell signal, it can, in no time, drain out the battery.
Example: If you are in a low reception area, the phone will try harder to get a signal. This will lead to the use of more power while successfully obtaining a signal.
Data Transfer
Battery Drain: Almost all push notifications and email services, app updates in the background, etc., are constant data transfers. Disabling cellular will disallow all such activities.
Example: If you turn off cellular data, then this way will stop the apps from updating and syncing, thus saving battery.
2. WiFi
Constant Scanning
Battery Drain: It keeps on scanning for all the Wi-Fi networks, so some of the energy is sapped even if you are not working with it.
Example: A phone that's out of range of any known Wi-Fi hotspots continues to keep searching for an available network, therefore wasting the battery.
Background Activities
Battery Drain: The apps and the system processes are updating and syncing data through Wi-Fi. By turning off Wi-Fi, this will prevent most background activities.
Example: Social media applications update content in the background and keep draining battery life.
3. Bluetooth
Device Pairing
Battery Drain: Keeping Bluetooth on means your device keeps on scanning and trying to connect with devices around it, which is a pretty power-consuming operation.
Example: Your phone would be using power searching for Bluetooth headphones or any other peripherals when it had to, especially when you are not using them.
Background Connections
Battery Drain: It keeps the devices connected to peripherals like smartwatches, fitness bands, or wireless headphones. Turning off Bluetooth preserves the power consumed in making these connections.
Example: A smartwatch is constantly syncing data with the phone and therefore, it depletes the batteries of both the devices.
4. GPS
Location Services
Battery Drain: Given that they are battery-intensive, GPS services communicate with the satellites quite a few times so that it gives a log of your location.
Example: Using navigation applications that play on GPS uses a lot of battery.
Background Location Use
Battery Drain: Most applications rely on background location uses to keep the applications running in their best potential such as location-based notifications, navigation updates, geotagging the photos, etc. Turning GPS off saves the battery from these background functions.
Example: Fitness applications tracking your runs or walks in the background use GPS, which is a huge battery suck.
More Tips
Lower the Screen Brightness
Battery Drain: Since you are in airplane mode, your phone will not be able to receive calls, messages, and/or app notifications, causing less background activity and power consumption.
Example: No push notifications from messaging applications equals your phone is not waking up and using power to display the notifications.
Low Power Mode
Battery Drain: You won't be using any communication features, and hence you'll use your device less. The less you use the phone, the lower screen-on time it logs, which directly contributes to saving battery.
Example: Getting less frequently to check messages or social media updates leads to less screen usage, conserving battery.
How App Management Plays Its Part
Battery Drain: Many applications are notorious for running in the background even if they are turned off. Airplane mode can shield you from that by shutting down the unnecessary processes.
Example: Social media apps, email clients, and even some games run processes in the background, which may be curbed by putting on airplane mode.
Settings for Maximum Savings
Battery Drain: One can add even more juice to the device while in airplane mode by tweaking a few device settings like keeping the screen dimly lit and enabling no system notifications.
Example: Keeping the screen to a minimum comfortable level and disabling the haptic feedback will be quite a considerable battery saver.
Specific Scenarios When to Make Use of Airplane Mode
Travel
Battery Drain: Airplane mode has to be turned on every time when traveling, more so for a long flight. This way, in addition to keeping the device alive and kicking for use, the battery will also last the whole trip because there will be no network service, and that is what airplane mode basically does.
Emergency Cases
Battery Drain: At least in such emergency situations, such as power outages and natural disasters, wherein the remaining life of the battery is crucial to battery life, airplane mode can really make your phone survive for a longer duration.
During the Night
Battery Drain: As you go to bed at night, switch into airplane mode. It conserves battery life and makes sure that your gadget is fully charged and ready for use come morning.
Example: By turning on airplane mode and disabling features such as cellular, Wi-Fi, Bluetooth, and GPS communication, you ensure a better method to save power for your portable device.
Airplane Mode: Myths vs. Facts
Does Airplane Mode Really Save Battery Life?
Answer: Yes, turning on airplane mode actually saves a considerable amount of battery life. When airplane mode is activated, several power-draining functions, such as cellular services, Wi-Fi, and Bluetooth, are shut off. Cellular services, in particular, consume a lot of energy since your phone constantly searches for the best signal, especially in dead-zone areas. Wi-Fi and Bluetooth similarly drain power because they are always scanning for available networks and devices. Airplane mode also prevents background processes from running, which saves even more power. Additionally, GPS is turned off, which otherwise continuously sends signals to and from satellites to determine your location. By turning off these processes, airplane mode allows your device to consume much less power, making the battery last significantly longer.
Can I Now Turn Off Airplane Mode?
Answer: It’s okay to turn off airplane mode when you need to be connected for calls, messages, or internet use. If you’re going to use your phone for communication, navigation, or going online, you’ll need to turn off airplane mode to stay connected and receive notifications. However, when you need to save battery life, like while traveling or in areas with no signal, airplane mode can be very handy. Similarly, if you want to reduce distractions or avoid interruptions, airplane mode can block out notifications and save the day. It’s fine to turn off airplane mode when you need all of your device's functions, but turning it on can help in situations where battery life or minimizing interruptions is important.
Is It Good to Keep Your Phone in Airplane Mode?
Answer: Keeping your phone in airplane mode can be beneficial, especially during meetings, flights, or when you want to save battery life. Airplane mode turns off all wireless communications, which saves battery power and prevents distractions from calls, messages, or notifications. It also stops your phone from constantly searching for signals in areas with weak coverage, which further saves battery life. The downside is that you will be disconnected: you won’t be able to make calls, send texts, surf the internet, or use apps that require network connectivity. It’s okay to turn on airplane mode when necessary, but don’t forget to turn it off when you need to stay connected.
What Is the Disadvantage of Airplane Mode?
