Re: Auto brightness or manual
In other threads, I've discussed the G3's battery life. Altho', as I've said above, I've had the phone on 0% and auto for brightness, I have had days of heavy usage where my phone struggles to make double figures in hours (average 12-14hrs). I carry spares, so it's no big deal, but last night and today, I thought I'd trial setting the brightness manually to see how the battery reacts.
What I noticed first was that the auto brightness tends to jump to a far higher level than I personally require in most situations. When I got off the train to work today and went outside in to cloud (I work in London - lots of sunlight isn't too common...), I hit auto (from 25% manual) and the screen lit up like a firework. When I manually adjusted it to match, it was on about 90%. Sunlight will obviously bump this to 100% I imagine.
In my office, under fluorescent lighting, auto tends to set it to 50-60% or so. At home, maybe 30-40%. On Manual, I've found 25% (so far) to be more than sufficient to see the phone pretty clearly most of the time. Obviously this will vary from person to person and by the climate where you are at the time, but I've used my G3 pretty much in the same was as the previous day, and I've got about 20% more battery than I did at this time yesterday. The battery monitor also says the Andriod OS is only 12% behind screen usage in battery consumption, whereas before my screen usage was accounting for far more of the battery drain, and was often double the OS.
All I'm saying is that it may be worth trying a manual setting instead of the auto if you're finding that the G3 screen eats power, like I have, as, even with Auto on, and set to 0%, the brightness adjustment seems to be anything from 20-50% higher than I personally require under most conditions.
