Most of the people nowadays have smartphone. It is like a essential needs for people. There are so many companies manufacturing smartphone. Different models of smartphone may have different battery life.

Battery low

Battery life is one of the most biggest selling point for smartphone nowadays. So, companies are working to extend the battery life.

Today, we bring some of the scientific tips and trick to increase the battery life.

Heat is the enemy of long battery life

A cell kept between 25 – 30 degrees Celsius (77 – 86 degrees Fahrenheit) should retain around 80 percent of its capacity after the first year even when cycling from empty to full charge. Battery capacity will be higher than this after a year if smaller periodic charging cycles are used. Raising the temperature to 40C (104F) sees this fall to just 65 percent capacity after the first year, and a 60C (140F) battery temperature will hit this marker in as little as three months.

Graph of battery voltage

Importantly, operating at a low voltage is good for a battery’s lifespan, increasing the number of available charging cycles before you’ll start to see a major reduction in capacity. Roughly speaking, every 0.1V decrease in cell voltage doubles the cycle life, according to Battery University. Therefore, charging up your phone in that 30 to 80 percent range keeps the voltage lower and prolongs the battery lifespan

Avoid the Gaming or watching videos while charging

Gaming

Gaming or watching videos while charging is bad because they distort charging cycles.The best way to avoid parasitic loads it to turn your device off while charging. But it’s probably more realistic to keep the workload very light while the device is plugged in, leaving it to idle most of the time. Remember to unplug it once the battery is topped up enough.

Don’t let your battery die

Try to keep batteries charged at an average 50% or above most of the time at the very least somewhere between 40% and 80% to preserve an optimal life span. Even though your charger can control electronic input to prevent damage, you should unplug the phone when power hits 100% and, if possible, avoid overnight charging.

Use dark wallpaper

Animated and bright wallpaper drain battery fast. On Android devices with AMOLED displays, black or dark wallpaper conserves battery life because the screen uses energy to illuminate only colored pixels. Also, dark wallpapers are easy on the eyes and look absolutely gorgeous.

Use battery-saving modes

Smart power saving mode
  • Reduce screen brightness. The easiest way to conserve battery life while maintaining full function is to reduce the brightness of the screen.
  • Turn off the cellular network or limit talk time.  The GSM is the most dominant energy-consuming component in a mobile phone, so it is beneficial to turn it off altogether or at least limit call time.
  • Use Wi-Fi, not 4G. With Wi-Fi being up to 40% less power-hungry than 4G for internet browsing, turning off cellular data and using Wi-Fi instead will help your battery life.
  • Limit video content. Video processing is one of the most power-consuming operations on a mobile device.
  • Turn on smart battery modes. This features modify central processing unit (CPU) usage for different apps, screen brightness, notifications and various hardware options to reduce energy consumption.
  • Use Airplane mode. Airplane Mode cuts off all radio signals to and from your phone, halting email, messages, phone calls, Wi-Fi, and Bluetooth connections. Swipe down on your Android Quick Settings tile and tap to enable Airplane Mode.

Extra tips: When should I charge my phone?
The golden rule to extend battery is to charge the battery somewhere between 30% and 90% most of the time. So top it up when it drops below 50%, but unplug it before it hits 100%. For this reason you might want to reconsider leaving it plugged in overnight.
