The longer your phone is in use, the less the battery holds a charge. This is mainly due to battery wear and tear and increased load due to unoptimised applications. In this article, we will look at all the different factors and understand why a mobile phone battery drains so quickly?
What are the factors affecting fast battery drain?
The accelerated draining of your cell phone battery could be attributed to several factors. One primary reason is the age of the battery. Like most technological components, batteries also have a lifespan, beyond which their performance starts to diminish. This is because the chemical reactions facilitating the production of energy in a battery slowly become less efficient over time, causing rapid drainage.
Another important factor is the brightness of the screen with which you use your phone most of the time – brighter screens consume more energy, hence if you have your screen brightness set at the maximum level or even moderately high, it could severely affect your battery life.
Most often users have to use the maximum backlight brightness after replacing the screen. Based on personal experience, we can say that in most cases non-original screens are used for replacement, manufactured in violation of production norms. The new screen is very dim and it is necessary to increase the brightness of the screen to the maximum that would normally use the phone. Sometimes the owner of the phone or the repair shop master buys the cheapest screen module for cheaper repair. As a result, the screen does not correspond to the quality, which negatively affects the quality of information display, stability of work and autonomy.
Moreover, the multitude of applications running in the background can also contribute to the quick draining of your battery. These could be social media apps running to keep you updated, GPS services tracking your movements, music or video-playing applications, and email services consistently syncing messages among other things. Particularly, certain power-hungry apps and games can drain your battery noticeably faster. Also, frequent notifications lighting up your screen or vibrating your phone, although they seemingly require little energy, cumulatively consume a significant part of your battery life.
Furthermore, using cellular data instead of Wi-Fi, or being in an area with a weak signal can further speed up battery drainage. This is because your phone’s energy consumption increases when it has to work harder to transmit signals during calls or while using the internet. Even the features like Bluetooth, location services, or live wallpapers can slowly eat up your battery life.
In addition, updates to your phone’s software, rather than fixing bugs and optimising system performance, can worsen battery life. Often after an update, new bugs may appear that increase battery drain. In the best case, developers will fix the bugs in the next update or after one update. In most cases the manufacturer’s support ends simultaneously with the release of an unsuccessful system update. In this case, there is no one to fix the error. Security patches can also become an indirect cause of increased battery drain. To eliminate vulnerabilities it is necessary to rework some software processes, sometimes affecting the increase in power consumption.
Extreme temperatures, be it hot or cold, can also put a strain on your battery. Exposing your phone to a high-temperature environment can damage the battery and diminish its efficiency over time. On the other hand, using your phone in a cold environment can temporarily degrade your battery performance leading to faster drainage. Finally, poor battery habits, like charging your phone all the way to 100% or frequently allowing it to drop to 0%, can degrade the battery’s health. Because most Lithium-ion batteries, which are commonly used in cell phones, have a finite number of charge cycles, overcharging and complete draining can lessen these cycles, thus reducing the overall battery lifespan. Therefore, the factors leading to quick battery drainage could be as diverse as the battery chemistry itself, encompassing the domains of habitual use, device settings, and ambient environment conditions.
The main reasons why do your phone battery drain fast
Phone battery drain can occur for various reasons, and several common factors contribute to rapid battery consumption. Here’s a list of the main reasons why phone batteries often drain quickly:
- Screen Brightness: High screen brightness levels, especially in combination with auto-brightness disabled, can be a significant drain on the battery.
- Background Apps: Apps running in the background, constantly syncing, or performing tasks can consume a substantial amount of power.
- Push Email: Constantly checking for new email using push notifications can be battery-intensive.
- Location Services: Apps that use GPS or location services can drain the battery, especially if multiple apps have access to your location.
- Wi-Fi and Cellular Data: Keeping your phone connected to the internet through Wi-Fi or cellular data can consume power when not actively used.
- Screen-On Time: Simply using your phone for extended periods, particularly for power-hungry activities like gaming or video streaming, can drain the battery quickly.
- Screen Resolution: Higher screen resolutions require more power to render, so phones with high-resolution displays can drain the battery faster when used extensively.
- Background Processes: System processes and services running in the background, such as software updates, maintenance tasks, and app syncing, can contribute to battery drain.
- Widgets: Live widgets or widgets that frequently update their content on the home screen can consume additional battery power.
- Notification Vibrations: Frequent vibrations for notifications can use more power than sound notifications or silent mode.
- Poor Signal Strength: A weak cellular signal forces your phone to work harder to maintain a connection, leading to faster battery drain.
- Battery-Intensive Apps: Some apps are not well-optimized and can use excessive power due to inefficient coding or resource-intensive operations.
- Background Synchronization: Apps syncing data in the background, such as social media or email apps, can use battery as they fetch updates.
- Live Wallpapers: Animated or interactive wallpapers can consume power, as they are running constantly.
- Old or Deteriorating Battery: As a battery ages, its capacity decreases, leading to shorter battery life over time.
- High CPU Usage: Heavy CPU usage, whether caused by an app, background process, or malware, can drain the battery rapidly. Использование не оптимизированных приложений часто приводит к работе процессора на высоких частотах.
- Auto-Sync: Auto-syncing of data across various accounts and services can be a continuous drain on the battery.
- Background Notifications: Frequent notifications from various apps, even when the phone is idle, can contribute to battery drain.
- High screen refresh rate. Most modern phones support screen refresh rates of 90, 120 or 144 Hz. A high refresh rate improves the smoothness of the interface when navigating. The higher the screen refresh rate, the more often the picture needs to be refreshed and the more battery power is consumed.
To extend your phone’s battery life, you can adjust settings, use power-saving modes, and be mindful of how you use your device, especially when performing power-intensive tasks. Additionally, periodic maintenance, such as optimizing apps and keeping your phone’s software up to date, can help mitigate excessive battery drain.
How do I stop my phone battery from draining so fast?
Firstly, it’s important to adjust the brightness of your screen or enable auto-brightness settings, as excessive brightness can significantly affect battery life. Apps running in the background can also drain your battery, so ensure to close any unnecessary apps when they’re not in use. Reduce the screen refresh rate to 60 Hz or use the automatic screen refresh rate selection.
Use a power control widget that helps manage Wi-Fi, GPS, Bluetooth, and other power-draining functions. Turning off push notifications and fetching data less frequently can help too. Another way is to disable any unnecessary animations and dynamic backgrounds, as they can also consume more battery power.
Heat can degrade the battery’s performance over time, so avoid exposing your phone to elevated temperatures. Utilize the built-in battery optimization settings on your phone to conserve battery power. Regular updating of applications can solve bugs that are causing faster drainage of your battery. Many phones also have power-saving modes that can be useful during such instances.
Furthermore, background data syncing can drain battery life, so consider disabling auto-sync. Always remember, letting your battery charge from 0 to 100% then letting it drop back to 0% can actually degrade the battery faster. Making these adjustments can prolong your phone’s battery life and help ensure your device lasts throughout the day. It is advisable to charge and discharge the battery within a certain range. It is possible to discharge the battery to 30-50% and charge it to 80-90%. In this case you can avoid overcharging the battery and increase the number of charge-discharge cycles of the battery.
It is advisable not to use fast charging technology. Fast charging shortens the charging time of the battery, while significantly reducing the service life due to high voltage or current. Fast charging also leads to additional heat, which has an undesirable effect on battery life. It is also not advisable to use wireless charging. During the charging process, part of the energy is transferred to heat and leads to battery degradation. It is therefore important to take care of cooling the phone when using wireless charging.
How can I tell what is draining my phone battery?
Recognizing what is draining your phone battery can be achieved by checking your device’s battery usage. On Android devices, you can find this in the Settings menu under ‘Battery.’ This section provides a breakdown of which apps are using the most battery power. On iOS devices, you can access this information under ‘Settings,’ then ‘Battery.’ This screen shows you the percentage of battery usage per app in either the last 24 hours or last seven days. Also, keep in mind that high screen brightness, frequent updates of apps, and background activity of apps can lead to significant battery drain. So, these parameters need to be checked regularly. Moreover, if you notice a sudden drop in battery life, it could also be due to a software update or an app that needs an update. If all else fails, you may need to consult a professional to inspect your battery life. Therefore, monitoring battery usage and managing your device effectively can make a significant difference in preserving battery longevity.
In most cases, battery discharge is accelerated by battery wear and tear. Even with careful use of the battery, after 2-3 years the capacity can drop by 25-30%. And if you regularly use fast charging, then you may need to replace the battery after 12-15 months of use. Another common factor is apps. Application developers devote less and less time to optimisation, which is facilitated by the annual appearance of new models of phones and tablets. In this case, updating an application can only worsen the phone’s battery life. In order to reduce the load on your battery, you need to optimise power consumption: disable unused functions, uninstall unused applications and enable power saving features. In addition, any optimisation may be useless if the battery is already worn out, so you will need to replace the battery as well. What questions do you have?
