I've mostly used iPhone until now, and as a big fan of Steve Jobs (not Apple) for years I was both satisfied but also incredibly getting bored and dissatisfied with the latest non-upgraded iPhones so I decided to switch. Boy was I wrong...
The reason why I mention the iPhone is that, since this is either illegal or highly aggressive against the user, the iPhone was always ULTRA stable, in that battery, phone, temperature was always linear (with of course slow decay of the battery) no matter what I installed or modified.
Now I've had a Galaxy S8 for 6 months, and while I didn't root it (except ADB-enabled it) or even updated it to Oreo, the Galaxy S8 is constantly changing my settings but also performance and temperature are changing from periods to periods without any inputs from me. And now, while I could except from 26h to 40h of usage (while using the same apps and settings), my battery has been going haywire and ****ed, and I can feel the S8 getting hot quicker than usual.

As you can see here, the Android System (listed as DeX) and the kernel which is constantly wakelocking, are screwing my battery without any changes on my end whatsoever (Pokemon Go usage is as expected and usual). A month ago, it was the Phone Radio screwing over my battery without any input, but still it had better battery. My question is not so much how to fix the battery usage (it partly is but I know how convoluted this can get with Package disabling actions) but rather: why the heck does the smartphone, samsung, google or god know what ****ing tempers with my settings and usages and suddenly the behaviour of the system changes screwing my battery despite every effort I make everytime to optimised it and disable non-system packages?
I gather XDA is not to best place to get answers. Why the heck isn't there any clear-cut list with description for popular smartphones and versions somewhere?

I had purchased it months ago when I got my Evo to save battery life but uninstalled it because the GUI was just horrible. I just downloaded it and the GUI has been made usable now. Oddly enough, JD is now able to control the CPU.
Has anyone given this a whirl?
the UI upgrade surprised me too. it takes a lot of poking around to get it really tuned in.

the old version was able to control the cpu as well
yes the new UI is great the maker just needs to fully support Gingerbread
I have been using it and recently did the update to the new one. I still use standard settings and it makes a difference on my phone. Think I am going to play with the settings to see what I can get.
Sent from my rooted HTC EVO using the xda app!
I am a long-time fan, and I set it up with advanced settings. Helps a lot with battery life.

I didnt know the old one controlled CPU as well seeing as though I ditched it sometime in Nov.
Use JD in the past but I have good battery life anyway (using SetCPU profiles, this may help) so uninstalled it.
Just tried the new one. The new UI is nice but I can not get to any meaningful settings (e.g. the nice setting page in Biofall's posting), just choosing a preset configuration. Was the free version dumbed down?
I am using CM 6.1.2
Just flashed, I can already see it behaving differently. Most notable it will not hold LTE in my house anymore (great).
I an tell you right now this will drain my battery faster its bouncing back and forth, back and forth.
Ugh.
Will report back with battery life.
I made sure I flashed with 100% battery to avoid any issues caused by this (it DOES happen, trust me, ask the devs who worked on the Atrix.)
Seems ok so far though, who knows maybe the radio is much better and uses less power. its been unplugged for like 20 mins and its at 99% with about 5 of those minutes in use. Not bad.
When my blue tooth is off it gets better battery than 4.3 but I can't really tell when BT is on...

My other phone's a Ferrari.

Yep, its been reported from various websites that KitKat completely borks battery usage, especially on Note 3's and Nexus devices. I've gone through three Note 3's as a result and finally gave up troubleshooting and gonna stick with Jelly Beat

I originally had the 10.1 (2014) Wi-fi version. It is not rootable without tripping KNOX and it had horrible battery life.
I now got the LTE version (T-Mobile P607T) and after rooting with TowelRoot (KNOX 0) and disabling all the bloatware, I got GREAT battery life right out of the box! I charged my tablet 100% while it's off for the 1st time and now I got:
- Almost 24 hours since last charged
- Almost 5 hours of screen on time with LTE and Wi-fi both ON
- 15% remaining
This is AWESOME!! I am sure it will get better after subsequent use and charge.
Sorry for the excitement, but I got much better battery life than my Nexus 7 (2nd Gen)!

Same here man! Even with 3d gaming (which I've seen many posts complaining about that in particular causing "massive" drain). I do use Greenify, Unbounce, etc. I'm easily good for the full day with it fully charged. My perspective is relative though, as I upgraded from a Note 8, which burned close to 10% just rebooting! So IMO, the battery life on this tablet is excellent, and easily comparable to my heavily modded / optimized Note 3.
This, perhaps, deserves it's own topic (and after explaining the procedure at length, decided I should just post one ), but especially after flashing ROMS, kernels, etc., make sure to calibrate your battery correctly! I think those instructions are worthy of a new topic (the info's here, but spread all over the place). AFAIK, none of the calibration apps work nearly as well as this, which is kind of the "old school" method, but it works very well! So I'll post that up, and definitely would recommend checking it out... It took me a while to figure this out, but I did discover how to do this on a tablet (without a phone / dialer) so hopefully that will be helpful to many here
Edit: Rereading your post, I was wondering what method you used to debloat? I'm currently semi-debloated, running xKat and freezing many system apps in Titanium (without negative effect), but then I've encountered permissions errors uninstalling system apps via that app. Just wondering specifically what method you used to debloat. TIA!

They are giving us the new Touchwiz icons that look like they are the result of Touchwiz being raped and getting a back alley abortion. Nooooooooooo. I hope they at least include themes so that we can hide that mess. Then again, by the time this is actually released by Verizon, I assume a lot of us will have already moved on to non Samsung phones.
I think the biggest UI upgrade I can recall occuring on a Samsung device was maybe when the OG Note got Jellybean and looked fairly similar to the Note II and picked up some new features. Otherwise, Samsung has traditionally let as little as possible trickle down from their latest flagships to "last year's" model when doing updates---look at the Note 4 or the Note 3 Lollipop situation , for example. Neither phone was as smooth or as refined under Lollipop as it was under KitKat (I do not recall if the Note 3 was better under JB or KK). I certainly do not expect things like theme support or manual camera modes to ever trickle down to the Note 4. I'll just be glad to get its RF and battery performance back to where it was with KitKat.
I highly, highly doubt we ever see this.

His demo phone seems to be very laggy as hell with MM 6.0. Hopefully by the time we getting this it should be better.
It looks like it has a few things I might like. But the icons, dear lord are they bad. Way to iPhoneish for my liking.
The settings menu looks decent to me though.

Exactly why I hope they throw in themes. I hope somebody asks on the youtube page. He's been answering questions. (I tried to ask, but youtube won't let me sign in since I deleted G+ and my YT channel.)
Post your battery and the period you have the phone,
to get there you need dial*#*#service#*#* on the numbers and scroll to "battery health test" (work on any stock ROM xperia)
mine is 2429 (out of 2700Mah) got my Z5C for 1.5 years

wow really good score, its seems you really save your battery.
(if you reflash\factory rest its need 2-3 charges to get accurate again)
but.. in the other hand ,my phone was 2850 when was new even its 2700 on specs.. so it could be
(maybe the charge optizmion bug i've got ruin's my battery life)

yeah I was surprised too. Actually I was expecting something worse due to the age of the phone, the fact that I never used the "battery optimization option" and my Z5C is often charged with almost full battery (using it in the car as alerter for speed cameras/traffic jams <- USB connected). Maybe the result is influenced by the fact that I lost the original power supply early, since then I am using the one from my old S4 mini with less output (I think 1.0A).
Last factory rest was when Android 7.0 was rolled out in Germany (by Sony - without provider branding). I checked it for the first time, so I can't say which value was shown when my phone was new , but I am looking forward to see results from other users.
2672000 here.
In use since Jan 2016 - 1 year 7 Months .
I'm one of those who become nervous when getting near 50% so it frequently hangs on the wire - several times a day, actually.
I was worrying about ruining my battery by this treatment, due to reading a lot about having to 'train' your battery by sucking it down to 15-20% at times. So this is all crap information, obviuosly.
Thank you for posting this code, btw.
Useful information!
