Wondering if there's a difference in speed when using Bubby's root method versus the ACE hack kit. I rooted my phone about a year ago, my GF just did hers a couple weeks ago, and I could swear there's a difference between the two handsets, though they're both Inspire 4G's. Just curious to know if there's anything to my observation, or if it's a case of things always taking longer when you're waiting for them, rather than when you're the observer.
What specifically takes longer on one than the other.

Oh, say for example things like opening and closing the app drawer, switching between apps, and general interface operations. I also find that my Favorites dialer widget tends to refresh a lot, particularly after a call - the icons will reload. That might be a different issue, but figured I'd mention it.

Probably speed difference due to what's installed on the phones. Number of apps. Type of SD card (maybe) things like that. It seems that the more I flash and change stuf on my pho.e the slower it gets. So I've started doing Full Wipes every few weeks. Even to my SD card taking everything off and only putting back what I actually use. It realmseems to help a lot. Also I've noticed that when a dev makes a full wipe zip for the Rom, that it works better when doing that along with the full wipe option you get with 4ext
Hope I helped

That different issue may be associated, as it sounds like you may be suffering from a bit of lag. Have you tried running quadrant tests for comparison purposes? Not all Inspires will perform exactly the same. My wife's Inspire has always gotten a slightly better signal than mine, while my GPS has always performed better than hers. There will be variances with processor as well, although it should be minor.

Let's not forget about ROMs. They all perform differently, too.
If you config them IDENTICALLY and yours is slower, then the proc/emmc may be inferior to what's in your wife's device. It's not unlike pc parts, you could have two kits of matching ram and one won't oc as well as the other. Same for processors too. Q6600 G0 SLACR will generally oc better than most other Q6600's.
Well, they're the same machine - Inspire 4G's, though I bought mine in March of last year from AT&T, she got hers in red from Target just about three months ago. The idea of variances between CPUs makes sense, though. Just figured I'd ask, since I hacked using Bubby's method and she used ACE, so I thought that might have made a difference.

Also manufacturers make plenty of changes throughout a product's life. Small revision changes that may reduce cost, increase stability, boost performance, sometimes lower performance. As long as it is not running 'poorly' then small differences are expected just with the enormous list of variables. Just take the faster phone and give her the slower one!

It could always be the rom. To compare better, you both need the same rom and version. With the app drawer, maybe you have the app drawer able to cache, and she doesn't? Just a guess.
Could be updated parts on her phone. I remember when I had my HTC Tilt when it came out then my sister had hers replaced a little bit before it was removed from the market and it was significantly faster than mine flashed with a ligh rom designed for speed.
Not exactly sure about this, but one would have to assume that battery charge levels could have an effect on the speed of the device and it's process speeds. the battery stays at nearly the same voltage during the charge cycle, but does begin to roll off as the battery power declines.
It could be said that decreased battery power would have a forced undervolt effect depending on it's level of charge, thus slowing down the device as it discharges.
Or....It's quite possible I'm full of crap, and have no Idea.

There's a voltage regulator in there maintaining the supply to the phone. The voltage you read in any battery monitor app is the voltage of the battery. The regulator should be feeding about 3.3-3.5v from that source, so once the battery drops below those levels, things die off. You are right, as supply voltages drop the phone wouldnt function at it's full potential, there is just circuitry providing the proper levels regardless of the battery's voltage.
I'm using current venomxl Rom with elemental kernel (all default other than max 1.5ghz and flu overclock off) and getting what I feel are amazing results on battery life. On phones of the past, aosp style roms pulled better battery life, but I saw here in the forums people were getting better battery life with sense roms? Is that true? I posted a screenshot below of my battery life, sorry couldn't figure out how to get jpg link from dropbox app.

Would be nice to hear what Rom/kernel combos others are using and what kind of battery life you are getting.
Put the picture in your public folder. Right click on the picture and click copy public link, or something to that effect then paste the link in your thread.
In any case, the only things you could do to get even better battery would be to undervolt your processor and maybe underclock as well. Some phones become unstable however and while I noticed the general ui and most apps run fine with a clock speed of about 1.2ghz, some, more CPU intensive apps do lag a bit. You can also disable radios when not in use. I actually use juice defender to do this for me automatically, which is pretty handy though not everyone likes the idea of having an app do that for you.
Last but not least, if your radio signal seems low most of the time, you can try flashing different radios to give you a better signal which will, in turn, increase your battery life.
Hope this helps, maybe others have had different experiences?
I use viper and bulletproof right now ad I wanted a stock kernel with swipetowake
And this holds up damn well in terms of battery life. Never used elemental for long though so not sure if it's better or worse.
*edit* I forgot to add, you can also turn off fastboot. Your phone will take longer to power on but saves some battery life.

Such reports are often just anecdotal and very subjective. Like you, I've also seen people claim better life on AOSP or certain ROMs on various devices, but never really experienced it in any consistent or meaningful way. Battery life often has more to do with the radio and reception in your specific care, than anything. Sure, various ROMs on various devices may have some subtle difference in battery life. But unless you are very methodical and scientific about comparing them, there are just too many variables involved, and you are often just left with subjective reports and placebo effects.
Can't open your pic. But if you are satisfied with the battery life (enough to call it "amazing"), I'd just go with the ROM that has the features you like the best, and leave well enough alone.
Did you know that Samsung has a system called DVFS that basically does nothing other than cripping your phone's performance with aggressive underclocking? There's a big thread about it here, but other than that, it seems that this issue is not very well known, which is surprising considering the SGS4 is a very mainstream phone. When I discovered about it I was shocked because this system does literally nothing useful, but it makes gaming or other high end smartphone activities (heavy browsing, 3D games, heavy multitasking, etc) lag like crazy.
It shocks me that Samsung has implemented such a thing and that you cannot disable without rooting (and obviously voiding the warranty and your Knox flag), and nobody except a few XDA users noticed.

Nothing? The phone already has extensive battery saving options, and it already has an underclocking option right there. Not to mention, swappable battery. Why is this thing enforced on everyone? If you use your flagship tier phone like it was an old Nokia from the nineties then it might not affect you. Since I use my phone for browsing internet, multimedia, and games, it does affect me a lot. I don't give a flying **** about one hour of additional battery when my phone slows down to a crawl. If I wanted to enable crawl mode I should have the option, the phone shouldn't decide arbitrarily when to slow down.
Also, if you really want to get into conspiracy theories, what makes you think this isn't a marketing ploy by samsung? To force users to get the S5 because the old one has such poor performance in games and stuff like that? The average smartphone user is so dumb he wouldn't realize it's all planned right in the system itself, they'd go " hurr, my phone can't run games well anymore, better go out and buy the S5, that will surely play games better, with it's multiple megapixels and cores and newer stuff I have no clue about".

Good points. I'm not arguing against you, btw, I'm not even sure how to tell if my phone is using it since I'm using Omega ROM.

Well, if you play any game or if you browse a lot you'd probably notice because performance drops a lot and lag increases. I don't know what Omega Rom is, this is an issue in stock rom. Of course it doesn't affect me anymore because I have the knowledge to research this stuff and eventually find a solution (even though I obviously have no idea how the solution is made), but for the average user this should be an issue, I mean everyone should know about it, it's too shady to be ignored, this is planned obsolescence at its finest.
Also, if this was introduced to save battery, how come so many people are complaining about battery drain on Kitkat?
It's obviously a marketing strategy, and I will spread the word about it.

I don't care and I don't have the knowledge to understand anything in that document.
What I care about is:
Galaxy S4 on 4.3 and under: great performance, no issues.
Galaxy S4 on 4.4: awful performance, issues.
Other phones on 4.4: great performance, no issues.
It's no coincidence this happened only a few months before the S5 is released.
Either Samsung did something wrong with this implementation, or they did indeed do it to force users to upgrade because the older model is no longer viable for high end smartphone use.

This has nothing to do with the user-space policies which you're complaining about.
Will deleting the twDVFS.apk be sufficient to disable this frequency scaling on my S4? Or is using the Xposed module necessary?

I have two U11 (I'm going to return one, or both) and I noticed significant differences in terms of battery life between them.
Running PCMark battery life test, auto-brightness OFF, brightness MAX, one phone consistently gets 4h53 of screen on time, and the other one 5h08 (from 100% to 20% battery). That's a 5% difference and it's not negligible. Phones are the same otherwise in terms of apps installed. Problem is, the phone that has the worst battery life starts apps a TINY bit faster...
So the bottom line is, phones have significant manufacturing differences.... and I don't know which one to return.
They have same firmware and all identical? are you sure? maybe some app is configurated different or something.. or one battery its more degraded
5% is close negligible. I've got two U11 and they don't perform any differently. You aren't going to get identical numbers on two different handsets running benchmarks.
Hardware parts may be more or less efficient than each other. Radios on one device may be a few percent better. Honestly just send one back and get it done with. You also forget about coy CPU variances (no two chips are the same).
Different bin could be the reason there is a slight difference.

Doesn't mean a battery benchmark is going to be within 0.1% the same as when you look at Youtubers who benchmark multiple of the same device and get somewhat different Antutu benchmark results.

It's like starting with a battery at 100% vs starting at a battery at 95%. For the rest of the life of the phone. Kind of a big deal.
Anyways, I'm running another test now with a low screen brightness, in case one screen was brighter than the other one (at max brightness) and drained more battery, I'll keep y'all posted.
Try with all radios (wi-fi, gsm, bluetooth, nfc, gps) off, even in location settings (disable scanning nearby devices for improved accuracy), and force stop all installed apps before the test. That gives me about 10 to 15 % increase on AnTuTu score. Maybe log cpu load and speed while testing as well.
I agree 5% is not a big deal, but would definitely keep the longer standing
Edit: force stopping because you may have installed the same apps, but most background processes won't load until you first time run their app, so one of the two "identical" devices may actually be running less apps in background. Best for testing would be to factory reset both devices and not load anything into them nor change any settings except the backlight for test.
How do you use both phones in the same manner to expect same result? You text same person with both phones making sure time taken to perform the task is same for both? And different phones have different usage pattern hence the 5% difference..??
Besides....that's 15mins. I definitely consider that as negligible. A 20% difference would be something to concern yourself about.
I am currently on stock Android 12. I flashed the unlocked stock image (non-verizon) a few weeks back. With Android 11, Android 12, LineageOS, etc. every browser I have tried including Chrome, Brave, Via, etc. all drain the battery way faster than browsers did on my previous Moto G5 plus. i would say when I am surfing the net on my browser (usually just reading forums, no video), the battery drains about 1% every 5 minutes or less. I have tried 2.4Ghz wifi, LTE, etc. and data connection type doesn't seem to impact anything.
Is this normal for this phone? anything to do to reduce browser battery drain?
If you go into battery usage graph, is the browser the only app listed as using up the battery (and not the screen brightness, or another app that may be contributing to the heavy usage)

correct. if I am using other apps the battery drain isn't near as severe. I keep the display setting "extra dim" enabled all the time and I keep it down as low as I can tolerate. I use a pitch black wallpaper use dark mode in browsers so they have mostly black background with white text.
Phone idle is the only other thing that seems to use a sizeable amount of battery according to the battery usage data in settings.
Sounds about right. Came from a Moto G7 Play (15 months back) and saw similar drain rates. All three devices have similar battery specs which plays into the units being used to assess drain. Is what it is.

I definitely did that. I only got the 4a because it was the perfect size and had a headphone jack. I assumed with a newer hardware set and similar sized battery compared to my old phone batter life "should" be better. Nope.
Na, it's more complicated. 4a sports more sensors, brighter/denser display, faster processors, etc. System and personal apps clearly play a role in longevity (behind screen brightness); you'd need to do a detail study to understand what's drawing when and why.
I use to fuss over such matters but find the device lasts a full day for my use case which is all that really matters. Charges up quick from a modest size battery pack when camping/traveling. Just like past Motos.
Not sure who I'll partner with in the next dance. Love Pixel cameras (especially in challenging conditions) and routine updates. Miss some of Moto's innovations, like active display and actions. Needs to be close to AOSP; no Samsung UX butchery. In the end form factor will likely be the deciding factor once non-contenders are ruled out.

I don't know what CPU you came from, but if the Moto only had "small" cores then of course it used less battery. "Big" cores use more power. They go faster too, but if you have a constant load, then they'll eat battery faster.
I don't know if there's a non-root way to disable the big cores, but I suspect you can do it with root (but don't know for sure).
Otherwise, you gotta get your browser to stop running JavaScript. If you're watching video you need to make sure the browser is offloading all the decoding to the hardware codecs rather than doing it on the CPU.
And if the screen is on, it might help to try and get it "more black" (eg. Use night mode) or turn down the brightness. The screen is often the primary user of power when a device is being used.

Thanks for the suggestions. My power complaints are just limited to the browser so I dont think it is just the larger CPUs. I think my standby consumption issues are related to Stock Android as I am now running GrapheneOS and my standby power consumption now matches my old Moto G5 Plus.
As for browser usage consumption, I have tried everything but disabling Javascript. I will try that and see if it breaks anything I use regularly. Thanks for the idea.
tangent back to general power consumption, I typically disable just about everything behind the scenes as I can. I keep the theme on pitch black. I use the extra dim setting to keep screen brightness as low as I can tolerate. I use night mode in browser to keep as much black background as possible. I disable all tap-to-wake or sensor based features. When I was trying to run Android 12, I disabled all the smart services and removed all the google apps I could. I removed all permissions I could. I restricted all apps I could. I disabled adaptive settings, etc. There is a bunch of stuff running in the background on Android 12 and I just could not

I dont think it is all the phone. GrapheneOS has 40% better standby battery usage than stock android 12. On graphene, it matches my old Moto G5 Plus. It is either lazy programmers with inefficient coding these days or it is google having the stock OS do waaaay too much by default with no way to disable it.
I'm trying to figure that out now.
