LG phone outshines Samsung and Apple in 'two-year' battery depletion test

Korean electronics manufacturer LG is the winner when it comes to making a smartphone battery that can stand the test of time - beating Apple's iPhones and Samsung's Galaxy series - according to the latest Hong Kong Consumer Council report.

The report showed that out of the eight mobile phone models tested, LG's G Flex performed best with its 3,500mAh (miliamp hour) battery, suffering only a 3 per cent drop in performance over a two-year span - which was created in a laboratory setting.

The battery originally held a charge for eight hours and 40 minutes, which fell to eight hours and 23 minutes after two years' worth of use.

The Samsung Galaxy S5 - LG's competitor on its home turf - with its 2,800mAh battery, lost 12 per cent of its charge, from nine hours 31 minutes new down to eight hours 22 minutes.

Apple's iPhone 5S and its 1,560mAh battery lost 13 per cent of its charge, from five hours 50 minutes down to five hours three minutes.

The consumer watchdog yesterday revealed the result of the seven-month experiment it conducted in collaboration with the International Consumer Research and Testing consortium. The experiment tested eight phones and six tablets of various brands for battery endurance.

The testing team simulated 24 months of use by charging the phone 365 times, assuming that users charge their phone once every two days. They attempted to replicate real-life scenarios by streaming online video on the device with Wi-fi on full brightness, charged it when the power dropped to 20 per cent, and kept repeating the process.
