First improvised LG G3 battery life tests show promising results

First improvised LG G3 battery life tests show promising results
LG didn't speak much about the battery life on its first phone equipped with a high-res Quad HD display - the G3. It simply clarified that the phone's endurance is commensurate with one that has similar specs, but a 1080p panel, thanks to the tailor-made "3A" technology. The "A" here stands for Adaptive, while the "3" indicates the three pillars of this system - adaptive frame rate, adaptive clocking, and adaptive timing control. Since the 5.5" Quad 1440x2560 pixels panel is made with the advanced low-temperature polysilicon (LTPS) technology, the screen is sipping power, and able to halve its refresh rate when displaying static content, like pictures, or article pages, just like with Sharp's frugal IGZO displays.

Still, LG hasn't outed official talk, standby, browsing and video playback times yet, so we can only guesstimate the battery life of the G3 to be pretty good, based on some tangential proof from improvised battery tests that are popping up here and there. 

First off, a prototype version of the phone has been put through its paces, and the phone lasted six and a half hours of video playback on a charge, as you can see from the screens on the right. That might seem average, but the test has been done at the screen's maximum brightness, which LG officially pegs at 430 nits, instead of the usual 150 or 200 nits, so the result from standardized routines like our own battery test, are likely to be much higher. 

Meanwhile, this video below popped up, straight from LG's homeland, where the G3 is already selling. The battery test method itself is a mess, as the guy tests streaming on-demand video through his carrier's LTE-A network, but keeps the phone in portrait mode, and often interrupts the test to see the battery percentage left. Still, he also tests the G3 endurance at the screen's full brightness, and clocks 7 hours and 47 minute of screen-on time out of the handset. The result is an hour and change higher than the previous test, as when you view the video in portrait mode, the adaptive frame rate tech likely kicked in for the static part of the image, thus helping the phone last longer than in the usual landscape mode that videos are watched in, and batteries tested. 

Nevertheless, more than six hours of screen-on time with the LG G3 display at a maximum brightness hints at a very promising endurance for the flagship, but we will know for certain when we put the G3 through our own tasking battery test, so stay tuned.

Impressive! Much better than Note 3.

Hmm no beside he doesn't show how he was using the phone. . For all it matters he could just leave the screen on without doing anything

In the article it is stated the use that was given to the phone, besides there are two tests mentioned and not only the video one.

It's better than a phone that is almost 9 months old!?!?!?

9 months old yet there have been no phones released that are really better than it to justify an upgrade.

Software buttons are so ugly when tinted.

It probably won't do better than Z2, S5, phablets etc. in battery life but it may come close, which is a good start

Doesn't seem like this will have the best battery life. Note 3 gets over 13 hours of video playback but this isn't based on full brightness. So we will just have to wait and see a real test

well, considering it has the resolution of the note 3x2 and with a brightness at an insane level, i think it is doing great

I wonder how much better the battery life would be with a lower resolution screen.

I had the privilege of using a find 7 next to my note 3 and I saw no significant advantages of the screen, the colors of my note 3 were actually far superior.

Longer entertainment on a larger lifelike screen. Yes to LG G3.

Think that my G2 wins over battery life compare to Note 3 and G3. Seriously my G2 has a 16hour battery life and it's 3000mah , 200mah smaller than Note 3 .

Call me crazy, but as far as I'm aware there is no screen that can change the refresh rate across specific sections of it, so I doubt that would be a contributing factor to prolonged battery life. More likely, it would be the decreased utilization of the screens available pixels. Portrait would use far fewer pixels to their full capacity/brightness (and thus less power) for the blackened portions of the screen than landscape would (having to use almost every pixel somewhat to display any color other than black).
