I've been running CM11 (feb 14 build) now for about 2 weeks with terrible battery drain during use. The phone gets really hot when i'm just browsing facebook or reading a news app.
I looked at the CPU usage and it seems it's either at max cpu, min cpu or deep sleep. That is strange first of all, it never or rarely uses the frequenceis in between. Then i took a look at the battery graph. When the phone is sleeping, the battery is holding really steady, but as soon as I start using it all hell breaks loose and the graph looks like an olympic downhill slope. The strange thing is that the main battery source is the screen which is odd beause on stock (With better battery life compared to this) Android System was the main battery killer.
I then took a look at BetteryBatteryStats. First thing i noticed: 50-50 deepsleep and awake which is pretty astounding.
The wakelocks are msm_hsic_host and PowerManagerService.Wakelocks. But this is strange because it's still pretty much a clean install.
So my theory is that the CPU governor is not functioning propperly and blasts to max cpu as soon as a wakelock is requested and when the phone is in use it also blasts max cpu. I don't know.. that's just what I think is happening with the data i have.
Any ideas?
Hey, was just wondering what settings you all have under Kernel Auditor in order to ensure 5 hours+ SOT. I personally have a dual core setup and have the other two cores kick in when the load gets to 90%, but this seems sort of sluggish now and I only get about 3.5-4 hours SOT and I don't play any games; just simple browsing and productivity. Others manage to get up to 5-6 hours SOT and I wonder how, I have NEVER been able to get this much. Standby is great though, 10 hours overnight and I lose only 3% battery. I am running on Pure Nexus Project ROM and latest Hells Core Kernel.
thats about the regular time I get outa mine. If I had to guess a lot of these 5+ hours are from watching videos or something that doesn't involve touching the screen. I've been using HC kernel with just zen decision on max performance settings and gpu on performance governor (since it idles 27mhz anyway might as well ramp up to full 600mhz for touches) for smoothness.
I have it setup that all my cores are on all the time, no hotplugging. ondemand/deadline, mpdecision disabled, fsync disabled. and I get 5+ hours sot every single day. no, I do not watch videos. but I do keep my brightness all the way down.
Hey, where do you go to disable fsync

it has to be an option in the kernel that youre using, at least the kernel has to expose it so that you can disable it. if its not xposed in general, then you cant disable it. im using despair kernel.
Try undervolting. Unless you severely under clock your cores you won't really see battery life improvement.
I keep my max CPU speed at 2803mhz. You might think "oh well if you're running higher frequencies then more battery drain". Not exactly. The difference between 2649mhz and 2803mhz will be negligible in terms of battery life so I'm seeing a slight performance increase with no significant battery loss. For example, on 2649mhz after a full day of normal usage I'd have about 49% battery life. On 2803mhz I'd have about 43%. I got a good performance increase and a more snappier device in terms of loading web pages, apps, opening documents etc so that extra 6% I lost doesn't matter to me, because its not significantly impacting me, I barely notice most of the time.
So yeah, the same goes for lowering CPU speeds to unless you significantly lower them. Putting max CPU speed to something like 2572mhz, you wouldn't even notice e the difference in battery. Now lowering it to like 1958mhz, or 2188mhz and you'll see a difference because at that point your severely under clocking.
You could also be draining your battery by hotplugging. That's why some people like Zen and MP Decision to keep all cores online when screen is on. If you use your device often, its better to have all cores running. If you don't and its kept in your pocket for hours at a time, hotplugging is the way to go.
Try under volting too. I do. Global Under Volt of -60.

undervolting doesnt really save you battery, but it does reduce heat. and hotplugging or having all your cores on doesnt really factor in when you dont use your device that much. as, if you have all your cores on or hotplugging, your phone should be in deep sleep anyways. it does make a difference when your phone is awake. i get much better battery life when all my cores are on all the time.
Should there be a sticky of suggested settings of differing requirements of speed, battery life, etc?

honestly, I don't think so. as the settings/setup used is always dependent on how you actually use the device. and many people have different opinions on how it should be set up.
Some phones exhibit choppy scrolling, especially when navigating long web pages when multiple apps are running in the background. Rate this thread to express how you smooth scrolling feels on the Sony Xperia X under such conditions. A higher rating indicates that scrolling is always buttery smooth, even when you're reading a 10,000 word article on "how to kiss a girl".
Then, drop a comment if you have anything to add!
very smooth, thanks to near-stock OS
Agree, it is very smooth all the time
if power saver mod is on! then many features are disabled to save battery and I experienced lags while
1. scrolling (in general)
2. whatsaap sending / receiving videos
3. browsing
however if you switchoff power saving mode! the device is smooth as velvet!

you can further access to the option of power saving mode - you still can get smooth scrolling in power mode. And of course, the battery consumption will be higher than normal power-saving, but lower than normal use
Hi. Probably not only me having that issue. When battery goes to 20% or lower smarthphone reduces it's GPU power and battery usage. Games became inplayable. I tried to find right settings and fix it but without a result.
I tried to switch off that Battery Optimilization (google-> "How to turn off battery optimization on Huawei devices" (I'm a new user and cannot post links) but with no improvement.
Is there any way to fix it? Must be some fabric setting.
Hello everyone. The title says it all. Please mention how much battery drain you are getting during 4k 30fps video recording.
I don't know if this is normal or not but my battery drain is 1% for each 75-80 seconds of recording. So about 40% of battery per hour. And does things like auto HDR or scene optimizer affect this?
Also, it's pretty hot in here in summar. My phone idle temps are 35c.
