I agree with what you said.

I have a question however. Does it really adjust CPU frequency on a per app basis, or more-so on a overall CPU utilization basis?

I'm more familiar with how x86 processors work, and those adjust based on CPU usage (or at least thats how Intel's "speedstep" works, not sure how AMD works).

But either way, this makes sense. The full power of the CPU is there when you needed, but it'll throttle itself when its not needed.

I used to do this kinda thing with SetCPU back on my HTC G2 lol.
[One (M8) General] ivicask:
Both, CPU governor still does hes job, and adjusts speeds according to usage.And if you lunch some app that is not listed in their profiles it uses default settings and governors.But when you lunch one of those apps they have profiles hard-coded in, you get more optimized results.

---------- Post added at 08:08 PM ---------- Previous post was at 08:04 PM ----------

Depends on usage, if your using lots of none HTC and none standard apps, costom kernel may be better, but if you use more regular stuff like Facebook, Twitter, YouTube, Skype, HTC camera, HTC browser ETC..You may get better battery with using stock kernel, or costom kernel that doesn't have PnP disabled..

Greenify doesn't touch system speeds, it simple puts apps to sleep, its not related to this at all.
[One (M8) General] Nippero:
I see. Thanks for the insight!

People should have no problem with this kind of "optimization"

It should really be welcomed lol.

I think the issue is people are getting it mixed up with actual benchmark "cheats" where the device would detect a specific benchmark, and force certain things to not be processed/rendered. I believe Nvidia got in trouble for something like this a few years back with 3DMark, something about not properly rendering shadows among other things.

Ive noticed pretty excellent battery life running skyfall on the verizon one m8 with faux123 kernel. Im running ART instead of dalvik with eco mode enabled using fauxclock. I underclocked to 1.2ghz as well so im running on only 2 cores always due to eco mode. Ive made it almost 2 days without a charge and even then I was down to around 18%. Im also an avid user of greenify and lux. Also i try to disable all of my notifications other than the essentials ie phone and messages. Facebook, gmail, snapchat etc only show notifications when i open them however this is the way i like it.

EDIT**

Performance is not an issue

I notice no lag
[One (M8) General] charismatickiller:
From what I have understood, lux does not save battery it merely lays a screen filter. That would be a placebo as it would, if anything, be using more juice.

HTC-ONE-M8
[One (M8) General] hipsh0t:
I use it to control my brightness when you go below 0% is when it starts to lay over a screen filter. I disable my auto brightness in the setting and lux keeps it at about at about 30% at night and 70% during the day i just enjoy the way it handles the the auto brightness more than stock. Below 0 or subzero is where the placebo would come in.

[One (M8) General] shox22:
If you don´t use your phone you´ll have xxxx times the awake time against your onscreen time.

Your awake time seems too high on your 14hours screen, but it depends on what you do with your phone.

Are you syncing a lot? A lot of messaging like whatsapp? Other things like music or downloads in the background? Playstore had to update a lot?

All things that increase your awake time.

High awake time´s doesn´t necessarily mean you have a wakelock problem.

On your 2nd screen it again depends on what you / your phone did in the time. You had playstore updates, that´s visible on your screen.
[One (M8) General] StuMcBill:
The only real thing I have syncing is WhatsApp, Gmail and Hangouts. Nothing else. I have greenified a lot.

Battery is killer. I have had the phone about a week now and it is amazing. Right now I am off charger for 25 hours with about 2 hours screen on and I am at 67%. Sweet.
[One (M8) General] bailey37821:
not so much

Its good to see most are happy with battery...but I came from an

Optimus G Pro

and I am skeptical of this M-8 (ive had it only 2 days though)

I'll download a good battery monitor later so I can post screen shots that give detail.

*Auto brightness is on with max at 100%

*Bloatware apps that run in the background for no good reason are disabled (all att apps)

*location reporting is on battery saver, gps not used

*Data off at deep sleep option is enabled

*I dont use widgets at all, so no other back ground services running

*I am on 4g lte 100% of time

First day I got it was at 50% batt from ATT. I shut it off and fully charged it. Just playing around with it for a few hours brought me back down to 50%. I ran it down to 15 % the next day. Shut it off and charged 100%, off charger at 0600. Work day for me so usage was very light.

10 minutes on net, 5 texts, 3 short calls, 5 minutes on play store, 5 minutes on gps, 10 minutes playing around with moving icons around on home screen. got home and used another hour of screen time just getting things set like I want them, downloaded swiftkey and dolphin, etc.

At 10 pm (16 hours of very light use, with 3/4 of that with screen off) I was at 20%

I'd be afraid with a little more use of the gps and google maps or maybe a little music time that I would not make it through a full day!!

with that type of usage I was hitting 2 1/2 days on my Optimus G Pro. I realize that my OGP was a little better than most phones with battery usage and size, but it sure did spoil me for good big batteries.
[One (M8) General] Nippero:
Okay so I got GSAM battery monitor yesterday and let it run to almost 0%. Here's the result:

This was heavier than my usual usage. I ended up reading comics on my phone at work (slow day.. Good Friday so literally 80-90% of the office was out).

Had 4G LTE the entire time. 3-4 bar signal in my office. Left screen on auto brightness.

[One (M8) General] BerndM14:
Is adequate for me and my usage. Can add another hour(minimum) to on screen as I was busy on phone until it reached 85 % I then changed to ART runtime and not on Dalvik anymore.

I don't know how long it was off of charge before I changed to art though. Just that the screen had more than a hour on it already.

Also I can't do full tests with wifi / mobile data. I only have wifi at home not at work, using a bit of mobile data her and there as it's expensive here in South Africa lol

Does all those apps have it's auto sync and auto updates on? Google Services doing app updates in teh back ground, google+ refreshing etc etc.

Should be able to save some if you take those auto updates off, I do it manually when I want to view new feeds, news etc, else why have it update at all? Doesn't mean anything to me while I'm sleeping, by the time I wake up the news changed again, what a waste of battery power then.

I also only do updates on Google manually, they can inform me and I'll do the updates manually.

P.S(Edit) Funny enough I don't see that screen on my GSAM battery monitor? I can't see time held awake...Where do you find that in options? I tried looking at the drop down and it only shows for kernel wakelocks or something but doesn't show which program was awake for how long etc?

The battery life is OK.

I am seeing lots of tricks here. WIFI Off, BT Off, No call duration...

Personally my note 3 can do 5 hour screen on time with BT, Wifi, 4G and a load of calls also. Not to mention max auto brightness. Then when its dead i swap it out.

Im finding it hard to want to go back to sealed in battery and charger cables.

I switched from Note 3 to Nexus 5 to M8.

I use my phone like a phone and I do not turn on any power saving mode at all. I see some people here using their phones like a tablet (airplane mode with wifi on) which is strange.....

With the same usage patterns (of course, I'm the constant here.), my screen time was/is:

Note 3 - 5.5 hrs

Nexus 5 - 3.75 hrs

M8 - 5 hrs

The M8's battery life is tremendously good despite the low capacity. Don't be fooled by it.
[One (M8) General] StuMcBill:

I'm on an offshore oil rig in the middle of the ocean with zero chance of ever getting a mobile signal, we do however have wifi. That's why I'm running my phone in that configuration, not for any battery saving purpose!

[One (M8) General] EtherealRemnant:
I'm incredibly impressed with the battery on this thing. I didn't disable anything, I don't use the power saver (as soon as it kicked in, I disabled it but I had already unchecked all the options in settings so it wouldn't have made a difference anyway besides the stupid icon), and all of my screen on time was spent playing Brave Frontier... That game brought my One to its knees, 2 1/2 hours if I was lucky and it turned my phone into a fireball as well. No fireball and much longer battery life with the M8!

I don't use bluetooth but Wifi, GPS, mobile network (LTE standby) all on the whole time. This is also just my first full charge (got the phone yesterday, ran it down til it shut off, charged it powered off for around 9 hours and then used it) so it will probably continue to get better. I also noticed that this phone charges FAST!

Extremely impressed. Kind of makes me wonder what would happen with power saver... Brave Frontier kills devices fast, it will kill my Nexus 7 in roughly 4 hours and my Nexus 7 usually averages 6 hours of screen on.

ROM details: Stock rooted T-Mobile, source-built kernel. Nothing fancy, haven't gotten that far yet.

[One (M8) General] jayr04:

Is there a way to make screen dimmer with auto brightness? I still find the lowestsetting still bright
[One (M8) General] jayr04:
Short explanations:

Prefer to have your phone alert you to incoming calls by vibrating rather than playing a ringtone? We understand the inclination; unfortunately, vibrating uses much more power than playing a ringtone does. After all, a ringtone only has to make a tiny membrane in your phone's speaker vibrate enough to produce sound.

http://www.pcadvisor.co.uk/how-to/m...mprove-smartphone-battery-life/#ixzz2zjqjvfWl

Switch off vibrate. Unless you really need that added awareness, turn off vibration. It actually takes more power to vibrate your phone than it does to ring it. Turn off haptic feedback too. Sure it feels cool, but it doesn't really add anything to your experience, and it's another battery drainer.

I'm getting 3 to 4 days out of my M8 between charges. Admittedly I am a fairly light'ish user but the 'power saver' mode really makes a heck of a difference (not 'extreme' power saving mode, just the normal one). Without that I get a days use out of the phone.

fairly good. Definitely better than my HTC one X and iPhone 4s. Would not say that it will last a whole day with heavy use. Yesterday i got around 13 hours with a lot of screen time, 4g, spotify, camera use and some heavy games for a short period of time.

But people need to know that screen time is all that matters (together with internet use and heavy usage apps). If you get 3 days you are not using the phone and if you leave the phone overnight it should barely decrease so what matters is how you use it.

Downloaded Gsam battery and will post results later. At the moment 87% left with 4h on, 1h screen time with 4g on, auto brightness. Medium usage with Spotify mostly taking up the screen time.
