[Q] How's kitkat? - AT&T Samsung Galaxy S II SGH-I777

How is everyone liking the KitKat Roms?
I'm thinking of upgrading because I'm getting pretty bad battery life with AJK 4.9 and Supernexus 2.0 (Android 4.1.2). I just got a new battery for my phone and that's when I realized that it wasn't my battery that was the problem.
BUT
My phone's charging port broke recently. Like, the innards of the port make a snap sound and fell out. So I have no USB functions on my phone any more so if my phone bricks mid update, I'm SOL. Also I am swapping batteries out half way through the day because my phone consumes power too fast.
So, any recommendations on KitKat kernels? Roms? I looked at RenderBroken's but I'm not sure if he's in the process of putting a new one up or what. The only downloads on his sight for the i777 kernels were in the "Old Builds" folder.
Also, doesn't holding the power button and both volume buttons boot into recovery? Because it's only going into Odin.
Preferences on ROM's?
Thanks in advance!

I'm sorry, I have a difficult time believing AJK kernel is the reason behind your battery woes. That kernel is very likely the most stable, tweakable, battery-friendly kernel ever made for our device, so if you are getting bad results with that... well, nothing else is going to improve matters.
A few things: stay in your current setup and run Better Battery Stats and Wakelock Detector. Between those two free apps you'll be able to see EXACTLY what's causing your problems.
KK roms take a bit more toll on the battery, and require a lot of tweaking to get things under control, due to the framework changes Google made. If you're worried about battery life you may be better off staying on JB until you discover the real cause of your battery problems.

I'm not worried about battery life so much as I just want to get through most of my day without having to swap batteries (which are brand new mind you). I updated to SuperNexus 3.0 so we'll see if there's any improvement of battery life.
What do you think about KitKat so far though?

I would advise you to stay off of Supernexus roms; they've long been abandoned and 3.0 especially was buggy. Try Renders' CM builds if you're wanting supported stable builds, or look in the ported section. Overall KK has performed great for me.

Ahhh but that means I have to switch kernels because I'm using AOSP. What about Render's 4.4 kernel? I looked at his thread but the link to the download only shows old versions. Are there any other 4.4 kernels working?

No, his kernels are great, you have nothing to worry about. Just make sure you thoroughly read what's required to make the jump to KK before you attempt it.

[Q] latest ROM for TB....

sorry, I don't have enough posts to reply to the already started thread over in the dev forum
http://forum.xda-developers.com/showthread.php?t=995819
basically I wanted to know, is there any way to flash to this latest "PG05IMG_Mecha" ROM from that Chinese site but NOT completely wipe the phone & lose all settings, apps etc. I spent the better part of the entire weekend setting up and tweaking all my settings just right. would hate to start from scratch but I do want the battery life enhancements of the latest FW.
cheers guys
No, currently there is no way just to flash that stock rom over top. What battery life improvements are in the newer rom?
Well I don't know the specifics but I believe they optimized the power saving algos a bit, I know HTC has been tweaking them to try to squeeze a little more life out of that tiny battery.
Does it also have a custom kernel? I know the largest battery savings I've seen from my experience w/ custom roms came from a custom kernel that was geared to save battery life.
I can't find any information on the thread you linked about it having any battery saving benefits.

No, the custom kernels to the extent of the Dinc are not available yet.

Yeah I know they've barely gotten roms w/ no bloatware out so far, which is a miracle in the turn around time from the device hitting the market. But sure they'll be there soon. So just interested in how this ROM manages to accomplish a battery savings.
Upon looking at the message in the thread about battery savings. If you remove bloatware and apps that constantly decide they need to be running you'll see a noticeable increase in battery life with that. You could also constantly fight to kill them and likely also see an increase in battery life. But the increase won't be as significant as when the custom kernels come about.
So if you aren't readily familiar with the manual process for flashing roms or say get a rom from a more reliable source (developer)... you might want to wait for roms to start showing up on ROM manager that'll automate the process for you and hopefully by then the custom kernels and other such options will be available. But I don't really trust a link for a image for my phone that sends me to a foreign website. You might want to check out adrynalyne's basic debloated ROM??

Battery life on Shostock3

Okay. So I am currently running shostock3 on my sgs2 with siyah kernal. I read the article from zedomax on galaxys2root.com that it has very good battery life and very stable but when i am running it, I have terrible battery life and i am currently underclocked or whatever the word is. Is there anyway to fix this?
My advice, run SHOstock3 as it was released. It runs great as shoman94 dev'd it.
...and stay away from that web site u mentioned.
Stick to XDA. Period!

Getting great battery life on Shostock3 V3.0. Flashed the AJK 1.52s kernel. Checkout Better battery stats...see if you have wakelocks killing your battery. And..I agree that website is no good..stick to XDA.

Most people get really good battery life on SHOstock3. Just search the SHOstock3 thread for the word battery to see what I mean. If you're not getting good battery life, you need to find out what in your configuration is causing the problem, and fix it. There is a thread in the general section started by Entropy512 that you should study to help you identify where the problem is.
I was on GB ShoStock for a long time thinking ICS and JB would never leave me satisfied on battery life.
http://forum.xda-developers.com/showthread.php?t=1353513
Finally came to my senses and tried out ShoStock 3 and have never looked back. To make it short the best Rom Ive ever flashed for any device I have had in the present and past.
You definitely have a rogue app killing your battery, find out which one it is and uninstall.

Sorry you have battery life problems.
I have been running Shostock3 since it came out (it's version 3.02 today!), but I also been on and off at least five (wow can it be that many?) JB roms on my SGH-i777 (won't even mention the # GB roms here!). After trying many, I must agree with the other posters who state that this rom delivers very good battery life when compared to stock and when compared with other custom roms.
Lately, it has delivered the best battery life I have ever had on this phone using any rom (although SlimBean JB provided very very good battery life for me recently as well! Also UnNamed was great for battery life in the old GB days )
I followed the recommendations made by creepyncrawly to read Entropy's (& others) battery notes/faqs. They provide some really good background, some with that typical "XDA flavor" (read technical!. That material, plus some more plain old simple user adjustments to how and what I use on the phone have improved my phone's battery time; and it might help you as well.
It really boils down to the fact that each phone user loads different apps and our usage patterns vary.
Assume that you've flashed it and let it settle for a few days and several recharge cycles. After doing this you can see what YOUR "norms" are. They may be good or bad, but that's the baseline for you with this rom and with the apps and usage pattern you have.
(You can tweak voltage and speed (well, not speed on SS3!), but my experience has been that the more noticeable changes will be by adjusting your pattern of use, or doing the "hunt for the app" (or apps) that are burning down your run times when not in use.
Not many here seem to like or do this, but I would also try one of those "help-you-with-battery-use" apps --like juice defender (Ok, I get that many here seem to think it a waste, but it really did help me --a little-- when I used it); or get DS Battery saver (a bit more aggressive and noticeable, but you also notice the lag while you wait for things to turn on when you want them).
Actually, these may not be precision solutions, and don't focus on your specific phone app use, but they do work in a macro way to slow battery use and simply working with them for a few days or weeks will provide you with a better a sense of what the heck is going on under the plastic; they will cause you to look at what you have/run and when.
Oh, this includes using Better Battery Stats, which is fine for reporting out exactly which the apps behave --or don't-- and by how much and when. I'm not slow (well, that slow but it frankly, it took me quite a while to figure out what I was reading in the BBS readouts and what they meant! (Now, after a year+ or so of using it, I don't even have it loaded, since I've done the fiddling I need --and BBS, plus those other battery apps, helped me to figure out what apps worked well, what apps I was willing to sacrifice battery on and what apps were useless and should be tossed.)
Finally, some roms just don't work for people! So it's not worth the frustration chasing something you may not be able to achieve with this or another rom. (You probably read how individuals have problems that you don't -yet, you run the same rom and the same phone! That is our world. So, too, you will read about some who make amazing claims on how long they continue on one charge. Some are pretty amazing, and some may even be real
My final five cents would be:
#1 run the rom a couple of days, get a baseline. Then switch from Jeboo kernel to AJK's latest for TW (I think it is 1.25ss, but I really also had great results from 1.48s) and run it a few more days. They were pretty much even for me, but others find one or the other kernel makes a real difference!). Compare after doing the same activities through a charge or two.
#2 If your battery life remains "poor," note what poor really is (ex. how much screen time? and how much total run time prior to getting to zero or 10-15%? ...something like that).
#3. Then get BBS and one of the "automatic" battery-saver programs and work with it for about 4-5 days and that many recharge cycles. See what your norms are but do it for the same type of usage!!! If better while using the battery fixers, then you can work at picking off the app or apps that are sucking your battery more than you want. Not as tedious as it sounds. Of course, staying with a rom for three weeks might be a challenge :laugh:, but this is a nice rom to work with.
#4. I don't think you will need to under-volt to get good BL. I wonder if your phone is stable in doing that? Or, does it induce additional lag? That might be a high price to pay for more run time. (You could compare the UV results with your "norm" as well!)
#5. Finally, we are on Galaxy S2 Sgh-i777 -and can change batteries all day long for not so much per battery! It is not elegant, but it works. (Done it myself several times -even with good battery life).
Good Luck!
Best ROM, Good battery life... been with Shoman's ROM since shostock2 never have a problem with the battery life...

[Q] how can i add smartass v2 governour and sio scheduler to padawan jb v4 rom?

Im new here and Ive been lurking around in the forums. I just installed jb v4 on my note i717. Any idea on how I can get the smartassv2 govenour and the sio scheduler? I dont have any of those and Id really like to have more battery life. And if not is there a kernel I can flash to have it and thats compatible with my rom? Im using trickster mod btw, Thanks!!

I have already directed you to the only alternate kernel that is going to work with Padawan. I am definitely no developer, but it would take a lot of effort just to extract those little options, not to mention the permission of the developer, and it would then most likely have to be installed into another kernel that could be compatible with Padawan.
I am not sure what it is that you are so intent on having those options for, I am sure you have your reasons. not sure that anything else is going to give you better battery life on a 4.1.2 rom. it seems with the progression from 4.0 through 4.4, the battery life is going to diminish a bit with every evolvement.
can I suggest maybe you try Black Jelly. the different rom may provide you that option. if not, Blownfuse has an alternate kernel list in that OP which was designed specifically for that rom.
good luck

My friend, its your phone. Out side of the governer and scheduler, battery life is the only feature you are bringing up. What kind of user are you?
Heavy video streamer
Big time gamer
Lots of music
Facebook addict
Various roms are going to provide various results. And no 2 devices are going to react the same. I know, folks have said this before, so sorry to repeat.
For what is may be worth, here is my rundown
4.O ICS ... most stable but may be lacking in some features
4.1.2 JB ... touchwiz based, the most stable JB your going to get
4.2.1 JB ... more features evolving into, but most unstable. Some able to control with alternate kernel. Battery life dwindling.
4.3 JB ... increased smoothness and improved stability. Still able to control with an alternate kernel to a certain extent. To me it started to become like medication. The phone seemed to build up a tolerance and stability would decrease. Decreased battery life.
4.4 KK .... did not have a problem with stability, but battery life has really suffered as is the complaint of many.
No rom is going to be 100% perfect. It is more of what can you tolerate for an inadequacy.
I love my music, I FB quite often, I'm on XDA several time a day and I have been catching a few minutes of Youtube.
My phone ran ORGASMIC on Padawan and I did enjoy Hellybean also. To me, battery is like gasoline, nobody is getting any better than me. Everybody pays the same at the pump. You can always get a Ravpower battery 2700 from Amazon for $8 and many swear it increase battery life immensely.
Wow, did I go on and on or what?
So what kind of user are you?

I would just take a few for a test drive then. if you had a problem with Padawan and random reboots, then my guess is you either had a bad download or your not flashing clean. a dirty flash is going to leave some straggling files from previous rom which are most likely going to conflict.
but try some different roms and let them settle. give them a couple days. if its not going to work for you, try the next.
one rom just wouldn't run on my phone and that was Carbon Rom. I tried several different versions, with and without alternate kernels. always clean. many swear by it and love it, that's why I kept trying it, but it just did not like my phone. no biggie, plenty to choose from.
don't take this the wrong way, but if you the only one suffering from a side effect, than it is most likely user error. there are many glitches throughout all roms and they are usually well documented in that thread.
refer back to my last post in Padawan. again, my flashing process may be overkill, but you cant get much cleaner than that
if a battery gets me through the day, I am good

Very common at about the 10 to 12 month mark. Battery starts to swell. You can get stronger battery for $8 on amazon.

i have 2 very focused questions:
What are the idle times with those different roms?
Are there some Main feature differences?
Aktually im running cm11 m5 snapshot with smartassv2 Governor. its smooth but the battery life is kinda poor.
Im looking for a rom with long battery life. And i dont care about google now, talking to my phone(ok google) nor i need the special features from the standart samsung rom.
Would be realy helpfull if u can review to my questions. Greetings!
pls apologize my bad english.
1 each phone is different depending on what's installed and running.
2 read there threads or flash each ROM and find out that way. You forgot about aokp?

There are no definitive results, I have used both and I keep coming back to Omni due to the fact that on SlimKat music stutters like crazy when the screen is locked. Also, Omni updates are small enough to update often without having to download a complete update, to many users this a huge deal due to data limitations in certain countries. As for usage, idle time etc, like stated before, that depends entirely on what is installed on your device. Install a bunch of apps that need to constantly receive data updates and you will have battery drain and very little deep sleep. Where features are concerned, you kinda learn to live with limitations due to missing features on a specific rom. If you really want, you can most likely find an app that will bring a missing feature to a rom. I see a lot of people throwing their toys out the cot because one of the other does not have a specific feature implimented, yet the developers have done so with good reason, usually either performance or battery life.
With all said, there are many roms out there, Omni and SlimKat aren't the only players. It's difficult to compare roms nowadays because you are never quite sure if your kernel tweaking or custom kernel with it's hundreds of tweaks is the reason for a device not going into deep sleep either.
Give them all a try and decide for yourself, nandroid backups and apps like Titanium Backup makes it so easy.

Thx for your long, interessting and helping text!
im missing only 1 thing. if someone flashes all roms, doesnt install any apps. Only new rom and full wipe before, restart and tracks the time the phone has battery. Dont u think this is a possibility to compare the roms battery usage? i think there is no one who does this, but i probably will try this and put down a little table here. so people like me are able to see the rom with the best battery efficiency. so if they decide this rom has not enough performance, they can switch to "battery efficiency Number 2" and so on.

Sure you can do what you stated but bear in mind how will you compare the battery life across roms..
There should be some standardized test... Like looping video playback or some other method which does not change based on you usage habits..

Pa is another you're missing from you're list of developed roms. What you could do is test video playback, calls incoming/outgoing,one game of choice "high end battery draining game" and compere them all. As for the kernel tuning.. Read about what really happens and you will fine not a lot does happen with UV/uc .

You can compare but you have to use that phone for more days not like just one and you have to full charge and then discharge 2 or 3 times till the phone make the correct battery stats. So i think you can test but better with daily use or get an app that drains battey faster well i think this may work

[Q] Battery or ROM fault?

Hi,
I have a rooted Galaxy S2 with CM11, Aug 8, 2014 build, with the original kernel (3.0.64-CM-g89e6992). For a while, I had excellent battery life, everything worked fine. But recently my phone would shut down before reaching 0%, at around 5-7-9. And when I turn it back on with the charger plugged in, it starts on a higher percentage. Before shutting down the screen flickers, and then suddenly it either freezes completely and I have to remove the battery or just shuts down. If I use the phone while charging, it would take ages to gain 1%*, and I have heavy battery drain.
My question is, is it because of the battery getting old or it is a ROM failure? Apart from denying certain options that seemed to drain battery in Privacy Guard I did not change anything that would require to get deeper into the system. Wifi is usually on, but location, sync or anything that could have heavy battery use is off.
Thank you for your answers!
*I'm not entirely sure, but I think the same happens if I charge it in flight mode.

Firstly, that is a really old build. There have been important fixes since then such as FPBug fix, and play services wakelock fixes which would be worth it on their own to flash a recent nightly(that is if you want to stay on cm11). I would have a guess and say the battery drain is probably a wakelock issue; using better battery stats or similar would tell you more. I wouldn't rule out the battery coming to the end of it's life either or even a usb port that needs looking at.
First thing I would do is transfer any data you want to keep to an sd card or computer and do a full wipe and flash a newer rom that is still being developed, such as cm11 nightlies or a sabermod version by @Markox89. If the issues persist, I would then look at replacing the battery, and then check the usb port. It may help to install the stock rom and re-root from there too.

Wow, thank you!! Which one would you prefer, cm11 nightly or a sabermod version? Also, are nightlies stable enough for everyday use? And what else should I consider ("that is if you want to stay on cm11")? Sorry for all the questions, I'm fairly new to the rooting scene..

Forget the "nightly" tag, the days of nightlies being unstable are gone(for the most part). The main difference between the cm11 nightlies and @Markox89 's builds is Markox uses sabermod toolchain to compile which makes the rom run a little bit smoother and a little bit more battery efficient. Otherwise they are the same. Read the last month or so of posts for more info HERE
Other roms to consider - it depends on what you want, stability vs newer lollipop builds; basic streamlined rom vs heaps of features.... I like small, fast roms vs the bells and whistles and I would have no hesitation recommending slimsaber kitkat by @fusionjack, but it's up to your own preferences -
For Slimsaber 4.4.4
For S2 Development thread for most of the roms being developed right now
