Why is your battery percentage going down while charging?

Are you experiencing a decrease in your phone’s battery level while it’s charging? If so, you might be curious about the reasons behind this issue and what actions you can take to address it. This article will explore the reasons why a phone’s battery may deplete during the charging process and provide tips on how to extend and preserve your phone’s battery life.

Why is your battery percentage going down while charging?

Outlined below are four primary reasons why your phone battery depletes during the charging process, along with corresponding solutions tailored to address each specific cause of the issue.

1.  Your Smartphone has WiFi/Mobile data “Enabled.”

When your phone is connected to the internet through either mobile data or WiFi, it may experience significant battery consumption due to continuous notifications from various apps, leading to a drain in battery life.

This situation is typically manageable for newer phones or those within a three-year range. However, for devices in less-than-optimal condition with persistent battery issues, charging efficiency is hindered by the simultaneous drain during charging.

Solution: If your phone has endured wear and tear and is struggling with battery problems, it is advisable to disable mobile data or WiFi during the charging process. This significantly reduces battery consumption, allowing for smoother charging. You can deactivate mobile data by accessing the toggle panel and selecting the Mobile Data icon. Similarly, WiFi connectivity can be turned off through the panel.

2.  Too Many Active Background Apps

Certainly, we often engage with numerous applications simultaneously for various purposes, including gaming, entertainment, and financial transactions. The issue arises when a substantial number (and by substantial, we mean a significant quantity) of apps are operating in the background, collectively consuming data in varying amounts, whether small or substantial.

Solution:

It is advisable to clear the ‘recent applications’ from your device before initiating the charging process. This action removes the most recently used apps from the background, preventing them from consuming battery power.

If you need to retain certain apps running in the background for specific purposes, it is highly recommended to assess which apps are consuming the most battery in the background. If unnecessary, clear them from the ‘Recent Applications’ while allowing essential apps to remain active.

All recently used apps contribute to battery consumption, often unnoticed as they run in the background.

To clear recent apps, click on the Overview button, typically located on the left side of the Home button. Alternatively, on some phones, you may use navigation gestures by swiping up from the Home button.

3.  Defective or a non-powerful charger or a charging cable

The depletion of your phone battery during charging may be attributed to an insufficiently powerful charger that fails to provide the necessary charge for effective charging. If the battery rating on your device exceeds that of the charger, it lacks the potency to charge the phone efficiently, resulting in slow or no charging. Consequently, the battery health diminishes, as is typical when the phone is not charging.

Another prevalent cause for your phone battery declining during charging is a defective charging cable or a charger lacking adequate power. In the case of a faulty cable, the process is reversed, leading to battery depletion instead of replenishment.

Solution:

Consider substituting the charging cable with another one and verify if the issue persists. Inspect the cable for any external indications of damage that might be causing the problem; if repairable, attempt fixing the cable and reattempt charging your phone.

If the problem persists despite these efforts, it may indicate an internal issue with the cable. In such cases, it is advisable to replace the cable with a new one, eliminating the need for potentially impractical repairs.

Should the problem be traced back to the charger, scrutinize its rating. If the battery rating surpasses that of the charger, meaning the battery rating is higher, acquire a more potent charger that aligns with your phone’s battery rating to ensure effective charging.

4.  Old or Damaged Phone Battery

Let’s acknowledge the reality: The primary reasons for your phone battery depleting while charging typically boil down to two factors – either your phone battery is damaged or it has undergone wear and tear over time.

Abrupt damage to the battery can result from various factors, while gradual damage may be caused by issues such as phone overheating or prolonged intense gaming. Damaged batteries lose their ability to charge rapidly, and if the battery consumption surpasses its charging capacity during the charging process, the battery will continue to deplete.

Conversely, the natural deterioration of the battery is a more conventional explanation for the decline in your phone battery while charging. Many Android phones utilize Li-ion batteries, which have a finite lifespan, after which their health starts to decline.

If your phone or its battery is aging, it’s highly probable that, at a certain point, the battery will start depleting while charging, especially if the charging process becomes slower.

Solution:

If your phone’s battery is defective or malfunctioning, it’s essential to visit an authorized service center for replacement or repair—the last available option. In the past, phones had removable batteries, especially those manufactured before 2014-15, allowing users to easily assess battery health by removing the back cover.

However, in current times, most phones feature non-removable batteries for space efficiency and a sleeker design. To ascertain whether your battery is damaged or worn out, seeking assistance from a professional is necessary.

If none of the troubleshooting methods prove effective, it is recommended to visit the authorized repair or service center for a thorough assessment of your device’s battery health. Depending on the diagnosis, you may opt for a replacement or repair, whichever is more suitable. If your phone is still under warranty, there’s a likelihood of receiving a free battery replacement or even a complete phone replacement.

Other reasons why your phone battery is going down while charging

Several other factors may contribute to your phone battery draining while charging, including:

  1. Charging your phone through your PC or laptop. While ideally, your PC or laptop should charge your phone, using the device during charging or experiencing high battery consumption can result in the battery draining instead of being replenished. PCs or laptops are generally less effective at charging phones, leading to slow refilling.
  2. The presence of foreign particles or dirt in the charging cable, causing a loose connection between the cable and the charger.
  3. Failure to use a certified or authorized charging cable and charger for your phone.

6 Tips to help preserve your phone’s battery life

Certainly, a phone’s battery possesses a designated lifespan; however, more often than not, it begins to exhibit reduced functionality well before reaching the end of its lifespan. Here are several methods to conserve battery life and extend its longevity beyond the ordinary duration.

 

Turn on Power Saving mode.

Anticipating a situation where your phone battery might fall short of its usual duration? Activating the power saver mode can curtail functions that tend to consume excessive battery life.

While various phones offer multiple power-saving options, phones sharing the same operating system may present different choices for Power Saving. Striking a balance between performance and battery life is achievable through ‘optimized’ Power Saving, adjusting screen brightness and resolution. Medium power saving mode, on the other hand, restricts data usage and lowers brightness and resolution to extend battery life. Opting for maximum power saving mode removes non-essential services and apps from your device.

Consider enabling adaptive power-saving mode, which overlays other power settings, managing battery usage based on your device usage patterns and pocket status.

To activate Power Saving Mode, access the phone’s pulldown shade, where you can modify settings to conserve battery. Additional power-saving options can be found in the device care section of your phone under Settings. Furthermore, specific apps can be completely disabled when not in use.

Watch your network data.

Whenever feasible, utilize the internet to minimize the strain on your battery caused by network data. It is recommended to keep your home or public WiFi on and connected whenever possible.

To cease the use of cellular data on your phone, you can disable mobile data services through the quick settings panel. Alternatively, you may employ Airplane Mode to deactivate data network features and transition to a WiFi network, although this action will interrupt incoming calls and text messages.

Manage apps on your phone

Numerous apps tend to run in the background, consuming data and battery life, even though developers strive for optimal efficiency. The App Power Management feature in the device care section of your phone allows you to place unused apps into a sleep state.

To prevent specific apps from draining power when inactive, consider setting them to sleep. Keep in mind that apps designated as sleeping or in deep sleep may require manual updates, as they won’t receive notifications unless actively in use.

Adjusting background activity or managing battery usage for apps can be done in the Settings section under the Apps category.

Be vigilant for ad-supported apps that excessively deplete battery resources. In-app ads, especially those running videos in the background, contribute to prolonged battery consumption. Despite not actively playing on the screen, these videos register as plays to advertisers, potentially resulting in unintended charges.

Regularly review the apps with the highest battery drain to identify and remove any outliers. Utilize the battery usage feature to determine which apps should be turned off when not in use and which can be allowed to run in the background.

Rethink Wallpaper and Widgets

Opt for static wallpapers to conserve energy, as animated displays require additional power. Choose backgrounds with fewer colors to reduce energy consumption, with black being the preferable option for OLED screens.

While widgets may be tempting, they are active programs that operate directly from your home screen, utilizing significant energy. If you’re experiencing poor battery life, it’s advisable to refrain from using widgets.

Avoid extreme temperatures

Prolonged exposure to extreme temperatures can adversely affect phone batteries.

It’s advisable to maintain your phone within optimal temperature ranges whenever possible. However, recognizing that controlling temperature is challenging in certain environments, consider employing some strategies. For instance, on hot days, shield your phone from direct sunlight using a thick case.

Leaving your phone in a confined space like a car with limited airflow can elevate its temperature. Unfortunately, some individuals leave their phones in such conditions, leading to an increase in temperature.

Heat is a permanent battery killer, causing lasting damage to battery capacity. Conversely, extremely cold temperatures can temporarily impact battery health.

When charging your phone, ensure it is done in a comfortable temperature zone, especially in environments with high ambient temperatures.

Review your app updates

Before updating your phone, it’s prudent to review app feedback.

Apps are a significant factor in battery depletion, running persistently in the background, refreshing, utilizing data, and sending notifications. You can manage this by suspending unnecessary apps in the settings.

Despite the continual addition of new features to these apps, it’s crucial to read reviews of the updates beforehand. This ensures that the new features don’t introduce bugs that could impact your device’s performance and battery health. A recently updated app has the potential to cause overheating or battery drain.

This advice is particularly relevant for those who check app updates periodically or update their apps daily.
