That's what I'm saying about SOT. It's a meaningless comparison. It's not even controlled testing and unless you all are testing SOT under some controlled method like doing nothing or video looping, what does it mean?

What is it spposed to mean when Joe posts 3 hours of SOT chatting on IM, but Bob posts 7 hours reading an ebook and Al posts 1 hour playing GTA. Am I supposed to say "WOW YOUR BATTERY LIFE DOES INDEED ROCK." No one even knows the formula to convert SOT with varying degrees of CPU and network activity so that you can compare.

Yes. Finally a smart post. I do think Franco has a decent advantage in active use too supposedly based on his hotplugging driver and how even the Thalamus driver was already better than mpdecision in terms of being conservative with cores onlining. I mean I don't suspect that Franco has a much better kernel than stock.

What's bugging me is the posts here that go "omg this is sooooo good. battery life is WAYYY better." For all we know half the posts on this thread are placebo. Franco himself has revealed the placebo effect MANY times when not telling us about updates he rolled back or inserted in his test kernels. So yeah, when I see stupid screenshots with stupid posts, it does get me wondering what useful data we actually have here.

Like I said. Anand got it. I could probably load stock and just let my screen sit there until it dies and take a screenshot showing > 6 hours. I don't doubt I could probably hit 6 hours on stock doing nothing, but what does that prove? Look at what the educated posters are saying. SOT doesn't mean anything because it depends on the user and what you're doing. I could get 6 hours reading an ebook easily in the dark. What does that prove? That my battery has enough capacity to drive a screen at minimum brightness for 6 hours? It's not even a kernel issue at that point.

I think you're not understanding my posts at all. What I'm saying is posting 6 hours SOT for Franco kernel doesn't show the strength of the kernel. Nor does it indicate that Franco's kernel is improving battery. If you run a controlled SOT showing 6 hours for Franco and 4 for Stock, then sure that's great. But no one's done a controlled test using a fixed test app or script yet.

You're right users have every righ to post battery screenshots and be happy about 6 hours SOT. They have the same right to post about their apps FCing and telling Franco that the latest update breaks TouchControl. It's about as useless as those comments.

And FYI, I never said stock kernel gives me the same results as custom kernels. You're just putting words in my mouth. I don't doubt Franco's kernel is better in battery. However, when you can achieve 6 hours SOT on a stock kernel that's doing active refreshing of a webpage EVERY minute (not just doing nothing), then what does showing 6 hours SOT in this thread mean? That you're better? If someone showed 10 hours or 24 hours or we saw consistent posts of > 6 hours SOT, then I could take that data and say "Wow, this kernel is leaps and bounds better than stock." Having people brag about their SOT doesn't mean every user can achieve that. That's why I'm critical about SOT data. Everyone's doing something different on their phone, and no one's getting significantly different SOT numbers compared to the 6 hours Anandtech got

It's kinda like phone benchmarks. I don't really care that Joe says this phone is fast or slow. If the phone is truly fast or slow, it would show on a benchmark. That's why there are benchmark discussions about Antutu and other scores. It's called using objective tests to compare.
