LG G3 and battery life - how much does the Quad HD display hurt?

The LG G3 has awed the industry with its 5.5-inch QHD display, but many fear for the effect this will have in battery life. Is there reason to worry?

The LG G3 just left everyone in awe, as is the case with most LG G series device announcements. It is miles ahead of its predecessor, and a step ahead its competition in many aspects. The display is stunning with a Quad HD resolution, design is gorgeous, build quality is solid and performance is strong.

But that crisp screen is sure to destroy battery life, right? Not exactly.

The problem with the G3’s amazing specs

Many of us are huge fans of what LG has been able to accomplish the past few years. LG’s Optimus G showed us what the Korean manufacturer was capable of. This was followed by the LG G2, which was considered a masterpiece of its time. LG created a fame for itself, especially in one department – battery life.

The LG G2’s battery life could be beat by very few devices out there. In fact, battery beasts like the Motorola Droid Maxx and the Galaxy Note 3 were the only ones able to touch it, and in some tests not even those could beat the G2.

Can the LG G3, with its 5.5-inch display, 3,686,400 pixels, 2.5 GHz Snapdragon 801 processor really live up to its family’s reputation in battery life?

I highly doubted it, which was the reason why I was so much against that Quad HD resolution display. LG swears they can keep up, though.

How LG is keeping the G3 alive

Today’s announcement sheds light on LG’s new battery technology. The company is naming it 3A, in which the letter “A” means Adaptive, and the number signifies the number of functions in the technology. These would be adaptive frame rate, adaptive clocking, and adaptive timing control.

It’s said this 3A battery technology can make the LG G3’s battery “last as long as a 1080p device” would. What it does is drop framerate (to 30 fps) when the smartphone notices there is no movement or activity in the display. This would go into effect when looking at a still image, for example.

Adaptive clocking and timing control deals with the processor, possibly under-clocking it when resources are not needed.

The bottom line

With this in mind, we can at least rest assured knowing battery life should be decent, if not above the competition. We don’t know if they can match the G2, but some precautionary measures were taken. We will have to further test this device to see just how well 3A battery technology works.

Yet, there is still a bottom line. All things considered, the LG G3 is still wasting energy. Imagine how battery life would be if LG kept all these specs, applied 3A technology and kept a 1080p display?

Surely, this QHD (2560x1440p) screen will display pure glory, but is it really worth it at such screen sizes? Will most people even notice the difference? What do you think?
