LG G6 battery life test results are out: can a 3,300 mAh battery handle a 5.7" screen?


The LG G6 is an exciting phone: the first mainstream phone with a 'full-screen', 5.7-inch display, it's actually smaller than last year's 5.3-inch LG G5. This became possible because of the new, taller and narrower, 2:1 display, but including such a bigger display meant LG had one more battery challenge.

A phone's display is usually the number one source of battery drain, so that's why we were curious to see the LG G6 battery life. The G6 features a 3,300 mAh battery, a big increase from the 2,800 mAh cell on the G5. Increasing the battery capacity is a great move on LG's part: poor battery life was the G5's weakest point, and we went into our battery testing with high hopes that LG has improved this year around.

So how is the LG G6 battery life?

Unfortunately, it is nothing to write home about: the LG G6 scores a score of 6 hours and 20 minutes of battery life on our test, slightly better than the G5 and G4. What does that mean for you? We have been living with the phone for the past two weeks or so, and we have found that it gets us through a full day of use and even lasts a bit more, but we have not been pushing it to its limits. If you start playing more games and taking more pictures you might need to recharge before the end of the day, but if you use your phone moderately, you should not worry about getting through a day without a trip to the charger. 

LG G6 Battery Life


Battery life (hours) Higher is better
LG G6 6h 9 min (Poor)
LG G5 5h 51 min (Poor)
LG G4 6h 6 min (Poor)
Apple iPhone 7 7h 46 min (Average)
Apple iPhone 7 Plus 9h 5 min (Good)
Samsung Galaxy S7 6h 37 min (Average)
Samsung Galaxy S7 edge 7h 18 min (Average)
LG V20 6h 23 min (Poor)
OnePlus 3T 5h 41 min (Poor)
Google Pixel 7h 45 min (Average)

In our benchmark comparison, you can, however, see that the LG G6 is outlasted by Apple's iPhone 7, the Samsung Galaxy S7 and the Google Pixel. The difference is not huge in some cases, but it is there. Interestingly, the LG G6 lasts almost as much as the earlier released LG V20.

Charging time (minutes) Lower is better
LG G6 97
LG G5 76
LG G4 127
Apple iPhone 7 141
Apple iPhone 7 Plus 197
Samsung Galaxy S7 88
Samsung Galaxy S7 edge 99
LG V20 86
OnePlus 3T 85
Google Pixel 119

The next thing we look when we measure battery performance is charge times: how much time it takes for the in-the-box wall charger to fully charge up the phone's battery. The LG G6 is quick to recharge, but it's not among the fastest: it takes 1 hour and 42 minutes for a full charge. This is slightly faster than the Google Pixel and much faster than the iPhone 7, but it's slower than the S7 and OnePlus 3T.

TL;DR


At the end of the day, we have the following LG G6 battery life testing TL;DR for you:

  • LG G6 battery benchmarks do not impress
  • In real-life, though, it has great stand-by
  • We get one day and even slightly more with average use
  • It is fast to charge, but not the fastest out there
