[Verizon] Screen-on battery time

[jackdubl]

I freaking love this phone, had it about a month, running AOKP b37 with leankernel 3.7. Except for one glaring handicap: battery life with the screen on. Don't use the phone, friggin' thing last forever. Turn on the screen, doesn't matter what for, and 20% will roll off before you can blink. It's kind of amazing. Anyway, I'm just venting and seeing if anyone else will be jumping to the SIII as soon as it's available, provided the battery life equals early indications that it is excellent.

Go into settings and change display to auto brightness. Open Rom Control... Performance... Color multipliers and change RGB to a lower number (try "default" first). I use .4666 for each, but it's a pain to adjust them manually.

Now auto brightness is a lower value and not so bright. You might have to turn off "auto" if you're outside in the sun tho.

The SGS III has an even bigger screen, and it's the same HD SAMOLED screen technology, so if anything the screen battery usage will be the same or worse.

The early testing result show the SIII performs MUCH better, due to a processor that advertises 30% less consumption.

I've only used auto brightness for years. I will try the color thing, but when I read imoseyon's disclaimer about the gnex's screen-on battery consumption, I decided there wasn't much that can be done.

Edit: I'm lowering that sucker. I'll post back with results. They were already set to default 0.4666

What does the CPU have to do with screen-on time? If it's getting better battery life due to the CPU, that's one thing. My point was the screen will be just as power hungry which should mean screen-on time will be comparable or worse.

Ok, and my point was if it gets better battery life, it gets better battery life. The tests they ran were continuous video, by the way, so I'm thinking the screen may have come into play there.

Source? The screen is by far the most power hungry consumer of modern smart phones. So my point is if the screen tech is the same and the screen is slightly larger, the screen on time should be virtually the same. I don't see how the CPU/chipset alone can translate to 30% improvement in battery.

Also it would be good to know if they were comparing to a GSM Nexus and also if it were running 4.0.4, because it is well known that 4.0.4 is better on battery than 4.0.2.

So I'd appreciate sources/links to see their testing methods.

9-10 hours of continuous video playback, and I believe that is for 90% battery drain. Tells me there is significantly less loss of current going on. Not sure if the S4 is supposed to last longer or shorter.

Thanks. The color multiplier did make a significant difference. Maybe now I can hold out till they show us what to expect from the next line of Nexus.

Well what kind of screen on times are you getting before having to charge?

 

[dall121]

Three hours... how about you?

 

[jackdubl]

I was getting 1-2 hours before, now closer to 3.

That's a pretty solid number. For me, I usually get somewhere between 1 1/2 and 2 1/2 so you may just have to get used to having to charge it in the middle of the day if you wanna keep the phone. Otherwise a Razor Maxx may be in your future.
