I've commented about this in a couple of threads but didn't get much of a response so I figured I'd start a new thread to test this out. I'm currently running Adrynylne's Basic debloat rom with the latest .9 kernel. Over the past week I've seemed to have on again off again good battery life to bad battery life like most other folks. Yesterday I was having one of those bad battery day's where my phone just seemed to drain constantly even while I wasn't using it. Like where you can just watch the percentages fall off a percent a minute. It just seemed like the cpu was running full clocked even while I wasn't doing anything with the screen off. I'm not one of those types that wants to turn all functionality off just to improve battery life, so just for the heck of it I setup a profile in Setcpu to keep the max cpu speed at 245 just while the screen was off. Immediately my battery stopped dropping off. I finished the rest of the day barely losing any. Today I've been running it moderately all day. As of right now I've been off the charger for 15 hours 39 minutes, with 1 hour and 36 minutes of display time on and 45 minutes worth of calls. I'm still sitting here with 53% battery life thinking at this rate I could get another day out of it. What I'm hoping for is that maybe a few of you would like to setup a setcpu screen off profile of min 245 max 245 and try and duplicate my results. Obviously you would need to be rooted to run this. Anyway this might be a big help to some of those that are suffering with bad battery drain, if this works across the board. Maybe HTC is running some kind of process in the background or something that clocks the processor up. Or who knows maybe it's just me. lol By the way I absolutely love this phone more and more each day and if my battery life continues like this I'll be totally satisfied. Thanks to all the devs, and thanks to all of you for your many useful contributions I've encountered here over the past year. Happy Androiding. dancedroid Note: Remember this test is mainly setup to improve standby time while the screen is off, it won't improve your battery life if you are playing with your phone all day . It may be helpful for those who are reading this thread to list a few details about what setup your running while using this tweak like, SetCPU Profiles: Rooted (Y/N): Rom/kernel: Screen Brightness setting: 3G/4G area: Time off charger: Noticeable improvement yes/no: Edit: Screenshot is from the next morning after leaving it off charger for over a day. I only lost 6% overnight.
