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!

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

Ya my note 3 did the same thing, i thought it was tye battery caz of the 8 dollar price. That is the conclusion i came up with too the phone was never really hot and 2 of those batteries swelled up making them unusable. I did upgrade the battery didnt have any more swell. I would like to know how that does happen though, i thought i was the onlu person that ran into this im glad read this post and hopefully can get an answer as im very curious if it was the type of battery or if was kernel. I cant remember the kernel i had but thought might be from putting too much speed in my rom.

Yeah. I want to know this too. These days i have been swapping between stock and cm 12.1 and on stock the battery amp ranges from 1200mah to 1800mah but on cm12.1 it always stayed at 1800mah and also phone got hot. It may be due to that or it may be because discharged this battery once to zero and then recharged it to 100 and then jump charged a couple of times. A lot of factors and this one was abused a lot so I can't put my finger on exactly what I did that caused this.
Hi there, i just wanted to make this post to know your battery stats and share mine too, for the 6045B (Idol 3 5.5')
In my case, i got a rom from 4PDA from 22FEB, i asked if i'm allowed to post it but i still have no answer, so i will just give the name
ROM_AOSP-6045Y (don't get confused on the name, it is based on 6045Y rom, and yes i installed the 6045Y rom into 6045B phone (Chile/Argentina Variant))
in this rom, i got the best results ever, and here i will share them
First at 32% (it is sort of mixed English/Spanish, don't pay attention to that)

as can you see, impressive (and i played some games in the meanwhile)
then i just played until 11%
Then, finally, at 1/2%, with this impressive SoT
And this is game time i played
in total 1 hour and 20 minutes of play time
i guess if i didn't played i would get more than 6 hours of SoT
I clarify that i use Battery Saver Pro and NapTime
so, what is your battery life? it is better? then which rom do you use?
Right now I`m getting something like 5 hours on screen using chrome, messenger, spotify at once (heavy use, like u can see) and modded with xposed, added google assistant with google ok detection and ambient display. LineageOS 13 with Greenify only
Still waiting for update, cause doze will be enabled and with luck I will get 1 or 2 more hours
Of course I still experimenting with CPU profiles
@MichaelGK nice, are you using the latest build or it is the first posted? i could not get more than 4 hours SoT in lineageOS, did you try Naptime or forcedoze?

Every app that doze not working cause there`s no enabled doze in LineageOS right now, it will be enabled at update... I think it should be online in few hours.
And I think greenify did the job better. It got force doze and much more features, also configuration is very simple. Best to use it with root and xposed.
For more features you can buy donation pack or just search for it, but better to buy, cause it`s worth this few dollars
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!
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?
