I've been using this for a day and I love the stability and speed! I note I have lost root access though.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] serathe:
You can enable developer options you can enable root access. (tap build number 5 times) >setup developer options > root access :)
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] StarFire_MK2:
Ah, I had enabled it but someone only set it to ADB. Now that I've switched it to ADB and APP, it works great. Thanks!

How's battery life on this new update?
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] thebasuke:
Is anyone else experiencing horrific battery drain?
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] Sonnto:
I have. To be honest, though, I've been experiencing bad battery (but this is the worst) since going to Lollipop in general. It could also be my device, but I can barely even charge my device. Even when it is shut down. It is stuck at 6%. I just drained it to 0% (shut off) and now I am charging it again. It also falsely says 100% but when I unplug, it goes back to 6%. It's really weird. I already recalibrated the battery percentage with that one app (forgot the name and I can't check bc phone is dead) But yeah.. lol.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] serathe:
Mine seems ok so far.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] thebasuke:
My battery is fine and I have a new one I use but this is the only rom I've used that has drain while charging.. it's a slow drain but it still drains while on charge
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] StarFire_MK2:
I just switched to this from a stock KK ROM and I find my battery life much better on this custom ROM.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] skytron:
Battery Life

I also have bad battery drain. I have a backup battery i got off amazon and i went through both them in like 9 hours with moderate use.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] thebasuke:
I'm trying to find the culprit but don't have any luck so far.. this phone had great battery life before I rooted it
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] tdotdot:
It's your device, not lollipop...
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] skytron:
Battery Life

This is ridiculous it might just be my device but i just bought a new battery and have greenified most of my apps.:crying::mad:
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] tdotdot:
If you're talking about the time left, it's not spot on at all. My hours left varies from like 23 hours to 4 hours.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] skytron:
The thing is its pretty much accurate. My phone loses battery faster than an iPhone 4. Even when its in standby it loses battery. The worst part is even when its charging it still loses battery.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] tdotdot:
Then there is something else going on. Check your battery stats and see what's killing your phone.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] manfromgta:
May I suggest in advanced WiFi options. Turn off (uncheck) "network notification" and "scanning always available." It may not be the culprit but it won't hurt.

Otherwise as mentioned, collect some battery stats to find out what is causing drain.

Edit: using Wi-Fi or data drains battery very quickly. I turn them on only when needed.

[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] serathe:
I agree with manfromgta, I keep my data/wifi off unless needed. Getting around three to four days. My wife keeps her wifi on, on her HTC so I set the wifi to turn off when the phone sleeps which helps with hers.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] sjamie:
If you turn off WiFi while sleeping, your phone will use Data. Isn't Data use more of a battery drain than. WiFi?
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] serathe:
Ah, sorry, on hers and mine data is always turned off. Our wireless plans here suck, so we only use data when we have to. :)
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] sjamie:
WoW! So you only get email and other app notifications when your phone screen is on?
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] WHib96:
You should install Gsam battery stats and use that to find the issue.

Does anyone else's phone seem to heat up A LOT and very easily with this rom? Mine does and it is EXTREMELY obnoxious, even when the max freq is 1 ghz. I've seen the cpu get up to about 55 C!!! I'm doing some testing to see if other roms have the nuisance. Let me know if this is also the case for you.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] bnook:
Hey quick question, is this the same build as the nightly 12.1s for att s3 on the CM page? If not what is different?

Thanks!
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] sjamie:

This Rom Comes With Deathly Kernel
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] thebasuke:
I experience the overheating issue too.. Only on cm ROMs never on tw ROMs.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] Sonnto:
I'm pretty newbie, and I downloaded the Gsam Battery Monitor. It said that 10.9% and 7.7% respectively were the highest drained by the Kernel and the Android system. Does that mean that the Deathly Kernel that comes with this build and Lollipop are draining my battery? I know my battery is bad as well, but I was wondering if that's normal. It said I used roughly 12% in 1hr 54m.

Currently at 84% with 30 minutes of SOT T_T lol.

If it is indeed the kernel's fault, does that mean I should just maybe update to the latest official CM12.1 nightly build?
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] sjamie:
With active use, I normally get 1 hour SOT per 20% battery drain.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] WHib96:
I honestly don't know and wonder myself what exactly this deathly kernel has in it. I've read some people say it's actually supposed to help with battery but my testing has shown no such results. There is no XDA page for it telling its features. Nonetheless, I haven't found it to drain the battery really any more than others.

So Android OS and the kernel are the top two within apps that are draining your battery, correct? That's expected. What's the percentage of your screen, WiFi, and other things it lists?

As for the nightly, I personally haven't messed with it because the nightlies are probably more buggy. I wouldn't mess with those unless you want to help test and report bugs. However, sometimes nightlies do have the fix that people are looking for.

I'm as of now looking around and testing different lollipop roms to try and find one that doesn't make the phone get so hot, so I'll let you know if I come across any that yield better battery life (and hopefully temperatures) than this one.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] vtails:
I have i747 ,I hadn't installed any nightlys till last nights and it stopped my Text message app(Stock one) from working it also changed my app's menu back to the stock one instead of scrolling. I looked at the log it says there's an illegal request in Java, I hate to start over. The message app works if I start at Contacts or if I get a text but doesn't work if I tap icon. I checked the build and no Deathley kernel. Trying to find a fix without starting over .
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] Sonnto:
Its not that big of a deal to me, since this is not my daily driver and is only a WiFi only device. I just don't want my once glorious S3 to go to waste :P

Thank you for the info and thanks in advance, should you find a better ROM. I'm getting a wee bit better battery now. It lasted me the whole day yesterday. It does heat up when prolonged usage is in action or when gaming a little bit. But its not a deal breaker. I've read one of these builds as one of the most stable and only recently updated to the 7/10 build. Its OK as of now. But iI do appreciate your alert should you find a ROM that yields better battery and less heating! :)

Going to flash this soon

I just want to know what the instructions are to flash this rom since it says it works with d2can.

I have TWRP with my boot system and data backed up.

So what do i do know to flash this rom + gapps with the latest super su?

My bootloader is ob1 as well.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] audit13:
What bootloader version is on the phone? You'll need the latest KK bootloader and modem for this to work.

---------- Post added at 04:53 PM ---------- Previous post was at 04:40 PM ----------

Flashing a d2att is no different than flashing a d2can as the latest TWRP for the d2att will work on the d2can.

You'll need to flash the latest TWRP to your phone, copy the ROM and Gapps to your SD card, boot to TWRP, perform a full wipe (system, data, cache), flash ROM, flash Gapps. If the ROM is not pre-rooted, flash supersu.zip from TWRP.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] WaffleYheGuy:
Is this rom pre-rooted?

And if i dont like this rom or it bricks my phone (probably wont brick) will i be able to get my stock rom back from my backup? (first time with custom roms lmao)

Hi,

My Device is an sgh 1747 at&t, but I'm using it @ India right now. It's stock rom was UCUFNJ1(4.4.2), I thought I'd give CM 12.1 a try, and I did, but TBH, I thought my stock rom really did give a long lasting battery and lesser heat and a better camera app. So, I restored the Backup I had made using CWM, but it kept showing "Unfortunately, gapps stopped working" over and over again. So, I did a factory reset, and everything was working good until I put my sim in -- now my IMEI was 'null', and the Baseband version was 'Unknown'. So, I thought I'll try to flash the modem.zip file for NJ1, couldn't find it . Found the modem file for UCUFNE4 instead, and decided to try my luck with that; therefore, tried to copy the file onto the internal memory of the phone; but alas, I couldn't. ES file browser said "Eaccess permission denied". So, finally, I Installed this custom rom; and now, everything is working fine. Phew.

If anyone knows a way for me to go back to my stock rom, please do let me know.

Regards.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] canodroid15:
Never ever try to downgrade your modem or bootloader. Had you flashed that NE4 while on NJ1, You'd been screwed! To get back to stock NJ1 look for enewman17s NJ1 stock rooted ROM. Don't flash any bootloader & modem files & make sure you wipe correctly.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] aj334:
Whoa!, Thank you.

There are 3 files in here: http://xdaforums.com/galaxy-s3-att/general/rooted-ucufnj1-stock-rom-t2985006 , should I download only the 'Flashable Rooted NJ1 system.img and boot.img' file and flash it using CWM after data wipe/reset, cache partition and delvik cache wipe? Or does the other files need to be used somehow too? :/ Newbie here..

Hi, I currently have this rom installed 'cm-12.1-20150710-UNOFFICIAL-d2att' . Am I supposed to update cm12.1 to the most recent version from 'cyanogenMod updates' in settings. Or should I be flashing a newer version just like I did with this version when it's available here?

Awesome job, by the way. This is fun! Thanks. :D
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] WontonNoodle:
So this is CM12 untouched right? It's just pure CM12 with the deathly kernel?

Phone doesn't boot on charge after battery drained to zero percent

The phone drained to zero percent. After keeping it on charge (the big battery icon showing up with charge percentage), it still doesn't boot on powering on. All I see is the notification LED blinking blue.

I am on cm-12.1-20150710-UNOFFICIAL-d2att, and wiped the cache partition and Dalvik cache before reflashing the ROM, to see if it would bring the phone back to life. The boot was stuck at the animating CM logo for an hour!

I did nothing else (no new installs etc.) on the phone except forgetting to charge it before the battery hit zero. Not sure if it's a bug and am the first one to discover it in this build.

I cannot afford to wipe data. Can anyone please help?
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] Perseus:
First off turn off and charge. Hopefully the animation &/or Led will tell you when full. Clearly what has happened here is that, some app or apps terminated abnormally at 0 % and have caused corruption in Dalvik.

Repeat the wipe and flash. When the bootanimation is on, connect to PC and salvage data what you can.

If you are stuck at boot again, that means probably there's a data corruption preventing successful boot. I do think, that means you'd have to bite the bullet.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] diando:

[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] niphoet:
I'll let someone else answer that. I just went back to kitkat, if that tells you anything.

I gave Lollipop a fair try (daily driver since April), but IMO it's the Windows Vista of Android (or maybe that was Honeycomb). No offense to any of the xda devs, just a clunker from Google.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] tdotdot:
On the latest nightly, rock stable. Clean flash though.

---------- Post added at 08:32 AM ---------- Previous post was at 08:30 AM ----------

Curious, why? I haven't had any problems, and the few I had were quickly patched. In fact, I'm astonished by how well the CM nightlies perform while being so damn stable. The only thing I'm not happy with is the camera (but I'm not going back to TW just for the camera) and the other hardware that TW was able to use like the eye recognition stuff.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] niphoet:
Mostly ram. I can have nothing running while in LP my free ram is somewhere between 12-20%. I've tried Servicely, Greenify, and others with no luck. I installed the last CM11 nightly and restored all of the same apps w/Titanium and my free ram is 45-50% with nothing like Greenify running.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] tdotdot:
I've read that that may be because lollipop handles RAM different from other versions. I haven't noticed any slowdowns on my phone even without greenify. I'd probably even go as far to say that lollipop without greenify is TW with greenify, battery wise. I haven't tried kitkat for too long so I don't have an opinion on it.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] manfromgta:
The reason for the difference is the way ram is handled. You are actually looking at it backward. Unused ram is wasted ram in android. Android is very good at learning how frequently and which apps you use most making them readily available.

It takes more time and battery to access an app that is removed from ram and consequently accessed from sdcard.

Good article here that goes into greater depth.

[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] WHib96:
I liked Kitkat quite a bit better than lollipop because it felt a bit smoother (probably because lollipop is still being developed) and it didn't make the phone so freaking hot all the time. I literally JUST had Evernote open this morning and my phone was getting noticeably warm. That didn't seem to happen as badly on kitkat. Thus, I just feel like something hardware and romwise is running inefficiently on lollipop.

HOWEVER, kitkat has some seriously bad camera bugs, none of which exist on lollipop. Back on kitkat, open camera was the only camera app I found to work without crashing and snapchat had some bad camera issues too. I didn't try it, but I also heard instagram and Skype suffered from camera issues too. It seems that they just couldn't get the camera worked out on kitkat, and that's a deal breaker for me. Are you just tolerating this or do you know of a fix?

I was always a bit baffled at how there were so many snapshot versions of cm11 for the s3, yet every single one had bad camera issues; the stock camera app wouldn't even work. Not sure how it just went unaddressed for so long. Perhaps because they were trying to unite all the s3 variants?
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] wrenhal:
Regarding the heat. The person compiling the nightlies for 12.1 has adjusted the soc temperature settings in the kernel and the last 2 weeks of nightlies do not heat up the way it did. The guy here has not changed it yet I guess.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] WHib96:
There's an option for adjusting that in trickstermod. What exactly is the "soc" temperature limit and what happens when it is raised or lowered?
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] wrenhal:
Not sure what the limits are but I think the guy has them set at 60 by default. Seems to stay pretty cool except when apps are refreshing after a Rom update.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] WHib96:
According to trickster mod it is set to 70 by default. Do you have any idea what adjusting that number actually does and why it makes the phone run cooler? I hope to see the update added to Twist soon!!

[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] jason2678:
It controls the threshold where the SoC will lower the frequencies of the CPU/GPU to control heat. Basically sacrificing performance for heat build-up.

What's best governor and I.O in your guys opinion for speed and battery savings?
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] jason2678:
Personally I like interactive / row with interactive set like this:

hispeed_freq = 918000

min_sample_time = 50000

timer_rate = 30000

I also clamp my max CPU frequency to 1350000. Good balance between performance and battery life for the way I use my phone.

As with all things tunable YMMV. If you play a lot of games or really try to multitask this setup probably isn't for you.
