Factors that draining your battery

“Apart from the screen, one of the biggest drains on battery life is the energy your phone wastes trying to find and connect to Wi-Fi or data networks. If you’ve ever noticed your battery plummeting while on a train, it’s probably because your device is working overtime to connect to a mobile network. “If you can connect to something stable, like if there’s WiFi on the train, it’s probably better to connect to that,” Griffith says. Reducing screen brightness and the time it takes your phone to go to sleep are also easy ways to extend your battery life” Matt Reynolds.


Tips and Trick to prolong your battery life

  • Update to Latest iOs, from iOs 13 Apple introduce  Optimised Battery Charging on iPhone. 

“ With iOS 13 and later, Optimised Battery Charging is designed to reduce the wear on your battery and improve its lifespan by reducing the time your iPhone spends fully charged. When the feature is enabled, your iPhone will delay charging past 80% in certain situations. Your iPhone uses on-device machine learning to learn your daily charging routine so that Optimised Battery Charging only activates when your iPhone predicts it will be connected to a charger for an extended period of time. The algorithm aims to ensure that your iPhone is still fully charged when unplugged” Apple 

  • In real life if you need to charge your phone during daytime always charge it from 20% to 80%.
  • iPhone works best at Room temperature (0oC – 35oC). If it is too hot, battery life will be reduced, if it too cold, phone wont work at best performance or slower.
  • Store half-charge if not using your phone in the long term. Recharge the phone up to 50% every six month.
