How to extend the life of your phone’s battery

If you have a smartphone, you are basically carrying around a pocket-sized laptop with a built-in camera and phone. Denser electronics have allowed for some powerful features to be built into a small package, but the weak link is the battery that runs it all. Battery energy has yet to match the quick growth of features on electronic devices.

Where does the juice go?

The power it takes to keep the device running all day depends upon what you do as well as your operating system, settings, and network (Wi-Fi, CDMA/GSM, 2G/3G/4G), but battery manufacturers say typical Lithium-ion (Li-ion) batteries provide up to ten hours talk time and up to 300 hours standby time.

Apps drain the battery. They sit in the background pinging servers, keeping track of where you are, and waiting for signals. Wi-Fi, Bluetooth, and GPS use power looking for routers and satellites or other Bluetooth devices. The display uses lots of power too, especially at full brightness and if you do graphic-intensive activities like play games.

The environment also has an impact on Li-ion batteries. They suffer from stress when exposed to temperatures above 30°C/86°F. This high heat accelerates capacity loss which cannot be restored. Likewise, cold can decrease electricity flow, making your device sluggish.

When do I need to replace my battery?

Conventional wisdom says you’ll probably need a new phone battery each year. Factors like charge and discharge cycles, exposure to high temperatures, and aging decrease performance over time. Manufacturers say the life of most Li-on range between 300 and 500 cycles. Beyond this lifespan, batteries gradually diminish below 50 percent of the original capacity.

If you notice that your battery depletes rapidly, fails to hold a full charge, or feels abnormally warm then most likely it’s time to replace your phone’s battery.

How to save battery life?

Battery Saver

Everyone knows it can take hours to charge a lithium-ion battery and depending on your use, it sometimes doesn’t even last through the workday. Here are some tips to conserve battery power.

  • Use Avast Battery Saver. Our free app from Google Play optimizes phone settings using ‘Smart profiles’ which activate automatically based on time, location, and battery level. This saves up to 20% on one charge.
  • Avoid full discharges and charge the battery more often between uses.
  • Limit exposure to extreme temperatures, especially heat. Don’t leave your phone in a hot car. Room temperature is best.
  • Lower your screen brightness. You can experiment, but usually anywhere above 50% is still readable. Some phones let you set it to auto-adjust.
  • Turn off vibrate, ringtones, and the flash on your camera.
  • Keep apps updated. The updates often improve battery usage by making the apps more efficient.
  • When in areas with no cell coverage, turn the device to airplane mode or even turn it off. Otherwise, the phone will continue to search for a signal and that eats battery.
  • Limit graphics-intensive activities like gaming and watching videos.
  • Turn off WiFi, Bluetooth, and GPS when you don’t need them.

The future of smartphone batteries

The race for a safe, cheap, long-lasting, energy-rich battery is on. With electric cars, wearable tech, and the Internet of Things running our households, inventors, scientists and business people are searching for the breakthrough that will change batteries forever. The next-generation of batteries may well be built with silicon-based electrodes, take advantage of the oxygen we breathe to recharge power cells, or be organic.

Just last week, a super-fast (1 minute!) chargeable aluminum-ion battery with a high-charge storage capacity developed at Stanford University was announced. This low cost, durable (it was able to withstand more than 7,500 cycles without any loss of capacity) battery is not ready to be mass produced, but it holds promise.

Until that time comes though, used the Avast Battery Saver free app to extend the life of your phone’s battery. 🙂
