Yeah, running his latest. Going to see how this voltage table I have now runs.

Default Am I Crazy?

I see pages back a report of 4h44m of screen on time and it says it's with the stock battery. I have all the tweaks installed in this forum plus the usual things like syncing off and brightness set low. I never see anything over 3h15m off screen on time. How in the world are you doing that? On a side note thanks for these tweaks they have definitely made my phone a lot more smooth if anything just haven't really helped with battery life.

Everyone's usage and phone is going to be different. Most have seen an increase in battery life with these tweaks and setup.

For those not following the Sprint tk thread these are the settings I've ironed out for Pegasus, after this run in going to mess with the freq rq, some people are stating that higher numbers here disables core 2 more frequently.

Castle, why did you choose row over Zen?

Yeah, did some testing on that and confirmed it a few days ago. I found a good setup for me was

hot plug_rq_1_1 : 250
hot plug_rq_2_0 : 150

It does disable cpu1 much faster but we don't we want it disabling too fast on heavy loads.

Are the phones different due to the kind of processor everyone may or may not have (fast, nominal, slow)? If so, is this the leading reason why some settings work for some, while for others they do not? Is this a testable theory? If it is, maybe we need to collaborate what kind of processor we have and then test settings accordingly to each. Mine is fast.

A couple reasons, while using ktoonservative I noticed that on heavy load I would see serious battery drain using Zen so I have an initial poor opinion of it. Second, and most important is this statement from the link posted on the op

Quote:
Run Queue: We know mutiple processes can run at once on our device. These active processes are placed in an array called a run queue along with their priority values. (Priority is used by the task scheduler to determine which process is to run next) To ensure each process has a fair share of resources, each one is run for some time period then paused and placed back into the run queue. When a program is stopped to let another run - the program with the highest priority in the run queue is then allowed to execute.
Row schedules tasks based on priorities with read operations placed over writes and quantums for fairness. My theory is tuning the scheduler to be as efficient as possible to help Pegasus (which uses a run queue based on priority) process what it needs to. This tuning and efficiency of the scheduler should help with battery life as well as performance. My goal has always been get as much battery life out of this device without sacrificing the experience. So I'm always aiming for battery saving but being just on the verge of lag, trying to stay on the low side of balanced.

Zen is very similar to noop and deadline, row is optimized to schedule tasks based on priority.

That's what I was thinking when I made that choice.

Do a thread search for nominal CPU I know it's been posted how to tell which you have. I'm sure as time goes on these guys will have it tweaked for both. Just takes time testing. Like today I know I can hit 4 hours screen on time but I often charge before I get out of work. Listen to music, text and twitter often. Definitely better than stock so I'm happy.

Implemented your tweaks to freq rq and you weren't kidding, while watching ktweaker for a while, I also have other monitoring apps but don't have the time at the moment, I hardly ever saw core 2, charging for another run, all in all I'm liking Pegasus.
