whether larger screen consumes more battery power

post #1 of 6
Thread Starter 
Smart phones drain battery really fast n it seems larger screens use more battery. So there‘s an entire market out there for batteries. I’ve tried OEM batteries and extended batteries from Mpj etc for my current Galaxy S Advance I9070, but actually that's normally depends on how much I use the smart phone. So whether larger screen consumes more battery power compare to feature phones?

Yes, of course, but it's not an issue if you think about it. Because of the larger screen, the whole phone is larger so the engineers have more room to place parts, including a larger battery than what's used on a smaller phone.

My OS is the largest contender for battery consumption, the screen is a distant second right now

This is only because of my user habits though

I would say the screen + quad core processor.

Especially on the display technology things like AMOLED is a bit better since it lights up the individual pixels.
Like my first phone was the LG Optimus One with a 3.2" with a 1500mAh battery and a Single Core 730mhz.
Over the last couple years I've moved to a Xperia X10 with a 4.0" 1500mAh battery and Single Core 1GHZ (felt a bit of a difference).
Samsung Galaxy S2 with 4.3" 1650mAh battery and Dual Core 1.2GHZ (felt the biggest difference)
Now at a LG Nexus 4 4.7" 2100mAh battery and a Quad Core 1.5GHZ (where the battery recouped)

I'd say if your really looking for more battery life without caring about bulk is to get one of those oversized batteries. They work, and are pretty awesome. (Kind of hard to do on a Nexus 4.)

Screensize and resolution do increase power consumption.

Screen technology and battery saving software are also important for battery life.

For example AMOLED technology spends zero power displaying blacks whereas LCD still uses power to display blacks.

The Samsung Galaxy S5 can enable Ultra power saving mode which turns the entire display into a greyscale mode, which allows the phone to have an extra day of usage even with only 10% battery remaining.
