What are the ways to extend battery life?

Extending battery life primarily involves optimizing the way you use and maintain your devices. Here are some practical tips to help extend the battery life of your devices:

General Practices

Lower Screen Brightness

Dimming the screen brightness helps conserve battery life significantly.

Manage Connectivity

Turn off Wi-Fi, Bluetooth, and GPS when not in use, as these connections drain the battery.

Close Unused Apps

Running apps in the background consumes battery. Close apps that aren’t in use.

Use Power-Saving Mode

Many devices have power-saving modes that optimize battery usage by adjusting settings like brightness and CPU performance.

Update Software

Keep your device's software updated to benefit from optimizations that enhance battery life.

Charging Habits:

Unplug your device when it reaches 100% to prevent overcharging, as this can degrade the battery over time.

Use Manufacturer-Certified Chargers

Use the charger provided by the manufacturer or certified third-party chargers to maintain the health of your battery.

Avoid Extreme Temperatures

High temperatures can degrade the battery. Avoid exposing your device to extreme heat or cold.

Specific Settings for Devices (Smartphones/Tablets)

Turn Off Vibrations and Haptic Feedback

These features consume more power.

Limit Background App Refresh

Reduce how often apps refresh content in the background.

Enable Low Power/Battery Saver Mode

This mode conserves battery by adjusting settings.

Laptops

Optimize Power Settings

Adjust power settings in your laptop for better battery life. Choose power-saving modes or settings that limit CPU usage.

Eject External Devices

Disconnect any unnecessary external devices to reduce power consumption.

Other Devices

Smartwatches/Fitness Trackers

Disable features you don't use, such as constant heart rate monitoring, and adjust settings to reduce screen wake time.

Portable Speakers/Headphones

Turn off when not in use to conserve battery.

Replace the Battery

If the battery life has significantly decreased and it's replaceable, consider getting a new one. Over time, batteries lose their ability to hold a charge effectively.

No Need to Charge 100%

Charging your device to 100% doesn't harm the battery in modern devices; however, keeping the battery at full capacity for prolonged periods may slightly impact its longevity. Lithium-ion batteries, commonly used in smartphones, laptops, and other modern devices, have built-in mechanisms to prevent overcharging. Once they reach full charge, the charging process stops, and the device typically runs on external power.

The concern is not so much the 100% charge but rather leaving your device connected to the charger for extended periods after reaching full charge. This practice, known as "trickle charging," can cause very minimal degradation over an extended period.

To Optimize Battery Health

Avoid Overcharging

Unplugging your device once it's fully charged can help prevent a constant state of trickle charging.

Occasional Full Discharge

Occasionally discharging the battery to lower levels (not to 0%) and then recharging can help with the calibration of the battery percentage indicator but is not necessary for lithium-ion batteries.

Moderation is Key

The real issue is keeping the battery constantly at full capacity or extremely low levels for extended periods. Using the battery in a moderate range (20-80%) can help maintain battery health.

Software Optimizations

Many devices and operating systems come with optimized charging features that can help extend the battery's lifespan. These features might limit charging to 80-90% and then finish the charge just before you typically unplug your device.

Remember, modern devices are designed to handle everyday charging and usage. Following best practices—avoiding extreme levels and prolonged exposure to a fully charged state—can help maintain optimal battery health over time.

You cannot charge it while using it.

You can, in fact, charge many devices while using them. Smartphones, laptops, tablets, and many other gadgets are designed to support charging while they are in use. Here are some points to consider:

Simultaneous Use and Charging

Smartphones and Tablets

These devices often support charging while being used for activities like browsing the internet, watching videos, or making calls. They may charge at a slower rate during intensive use, but they still gain battery power.

Laptops

Many laptops can be charged while they are in use. Some gaming laptops might require more power than their chargers can provide during intensive gaming sessions, causing a slow battery drain even when plugged in.

Limitations and Considerations

Charging Speed

Some devices may charge slower while in use, especially during resource-intensive tasks that drain more power than the charger can provide. This can result in slower charging or the device maintaining its charge rather than gaining power.

Heat Generation

Charging a device while using it can generate more heat due to simultaneous power consumption and charging. Excessive heat can impact the device's overall performance and might affect the battery life in the long run.

Gaming or Resource-Intensive Tasks

During heavy use (like gaming or video editing), the device may draw more power than the charger can supply, resulting in a slower charge or a stable battery level rather than an increase.

Optimal Charging Practices

Moderation

To maintain optimal battery health, avoid constantly pushing the device to its limits while it's charging. Giving your device some rest during charging can help manage heat generation and optimize charging speed.

Heat Management

Ensure proper ventilation and avoid covering your device while charging and in use. Excessive heat can impact both the battery and the overall performance of the device.

In general, charging while using a device is safe and feasible for most modern gadgets. However, it's essential to be mindful of the limitations and manage heat generation for better performance and battery longevity.

Avoid over Discharge 

Avoiding over discharge is a crucial aspect of maintaining the health and longevity of your device's battery. Over discharging a battery occurs when it's drained to extremely low levels, which can lead to irreversible damage, especially in lithium-ion batteries commonly found in smartphones, laptops, and other portable devices.

Here's why you should avoid over discharging:

Impact of Over Discharging

Battery Damage

Over discharging can cause the battery to drop to voltage levels where it can't be recharged. This damages the battery's ability to hold a charge and, in severe cases, may render it unusable.

Reduced Lifespan

Regular over discharging can significantly reduce the overall lifespan of the battery. It can cause a faster decline in its capacity and performance over time.

Best Practices to Avoid Over Discharging

Monitor Battery Levels

Keep an eye on your device's battery levels and try not to let them drop to extremely low levels (usually below 20% or even higher if possible).

Enable Low Battery Alerts

Many devices have low battery alerts. Pay attention to these warnings and recharge your device promptly to prevent it from reaching critical levels.

Avoid Draining Completely

While it's not harmful to occasionally let the battery level drop lower, it's best to recharge before it reaches critically low levels, especially repeatedly.

Use Power Saving Modes

Activate power-saving modes when the battery level gets low. These modes adjust settings to reduce power consumption and can help extend the battery life a little longer.

Calibration and Maintenance

Calibrate Battery Levels

Occasionally allowing the battery to drain to lower levels (but not 0%) and then recharging it helps calibrate the device's battery percentage indicator for accurate readings.

Conclusion

Overdischarging should be avoided as much as possible to preserve the health and performance of your device's battery. Being mindful of battery levels, enabling low battery alerts, and practicing regular charging can help prevent overdischarge, ensuring a longer and healthier battery life.
