How Graphic RAM helps the LG G2 add 10% battery life on a single charge
The LG G2 uses something called Graphic RAM to help extend battery life on the device. The name Graphic RAM is LG's own term for a technology called Panel Self Refresh. It comes into play when you are looking at the display on the phone and nothing is moving. This could happen while reading a website and the screen is static. With the usual technology, the display panel is being sent the same image by the GPU 60 times per second, which eats away at your battery life. When there is a change, the GPU sends out the new image and the cycle is repeated.

Graphic RAM (GRAM) replaces the constant communications between the display panel and the GPU when the screen is static by adding a memory cache, which displays the same image over and over and over again. When both the CPU and GPU both realize that nothing is changing, a screen capture is made and displayed. This allows parts of the SoC to shutdown, saving battery life and energy.

This is all happening incredibly fast, as you can imagine. The bottom line is a 10% increase in battery life. There are sure to be times when you will be grateful for every extra second of usage you have thanks to GRAM, before your phone shuts down.

I ´m happy that LG has now independent techniques and not stealing everything from other brands.

Do you work for LG? Because I personally don't care if any companies steals a technology aslong as I'm buying a phone with the best features and battery life, us customers will have all the benefits.

Wrong. The more there are thieves around, the less will there be R&D made, and the worse will the products sold to customers be.

This technology is from 2011 with the introduction of embedded display port 1,3, this is absolutely not new, however it is new in phones so I will give it to LG, but this is not LG technology however LG is the first to put it in phones.

Great, GRAM works when everything is static.

In PR LG says that G2 is still comfortable to hold in one hand. I don't believe them, but GRAM is really great (if It boosts battery life on average use).

I thought this was a technology dating from the first LCD screen on the market... Shocked to see that this was not implemented in phones until today ? Nice move tough

Someone need to implement translective LCD on phones. That'll surely save more battery!

Looks like a good patent.
