We all know how frustrating it is when your phone battery starts giving up just when you need it the most. Whether you're travelling, streaming, gaming, or attending back-to-back video calls, noticing your battery draining fast can be a real buzzkill. But what causes this to happen? How can you fix it? Let's dive into some of the most common reasons behind battery discharging too fast on both Android and iOS devices, and what you can do to get the most out of every charge.
Why Is Your Battery Draining Too Quickly?
There isn’t one single reason for a fast battery drain issue; it’s usually a mix of factors, from app behaviour to system settings. Understanding these technical reasons can help you stay one step ahead.
Background Apps and Services
High Screen Brightness and Refresh Rates
Poor Network Signal
Outdated Software and Apps
Push Notifications and Widgets
External Weather Conditions
Many apps continue running in the background even when you're not using them. Social media, location services, and real-time syncing apps can quietly drain your battery. On iPhones, background app refresh can be a culprit. On Android, auto-sync and app permissions are worth checking.
Keeping your screen brightness at maximum or using adaptive display settings can significantly contribute to battery draining too fast. Devices with high refresh rate screens (120Hz, 144Hz) also consume more power. Adjusting these can make a noticeable difference.
Weak network coverage forces your device to work harder to maintain a connection, leading to battery drain very fast. Your phone uses more power searching for a better signal or switching between 3G, 4G and 5G repeatedly, something that’s especially common in areas with fluctuating signal strength.
Running outdated versions of apps or OS software can cause unnecessary battery draining too quickly. Developers regularly release updates that optimise energy usage, fix bugs, and improve performance. Always keeping your system up to date is an easy win.
Widgets like weather, news, or health stats often refresh data in real time. Similarly, allowing all apps to push notifications continuously adds to the battery draining fast. Fine-tune what apps can send alerts and when.
The outside weather temperature has a significant role to play as well. If you are using your phone in cold weather, the battery will drain considerably faster due to the slowing down of chemical reactions in the cells. Hot weather does negatively affect battery life, but less than cold temperatures.
Fixing the Battery Drain
Now that you have identified the causes, here’s what you can do to stop your phone’s battery from draining too fast.
For Android Users:
- Turn on Battery Saver Mode: Found in Settings > Battery. It limits background activity and visual effects.
- Control App Permissions: Go to Settings > Apps > Permissions and disable unnecessary access.
- Optimise Screen Settings: Reduce brightness and switch off high refresh rates if not needed.
- Disable Auto-sync: Especially for apps you don’t use frequently.
For iOS Users:
- Enable Low Power Mode: Located under Settings > Battery. It temporarily reduces background processes.
- Turn off Background App Refresh: Go to Settings > General > Background App Refresh and customise app settings.
- Location Settings: Limit location access to “While Using” instead of “Always”.
- Keep iOS Updated: New updates often include battery life improvements.
For both platforms, it’s also a good idea to occasionally check your battery health (available in Settings in iOS) to monitor the long-term condition of your battery. If you phone is experiencing reduced battery performance due to external temperature, trying to keep it warm or cool might help.
