[Q] Custom ROM´s and battery drain

Hello fellow Galaxy owners,
I have been installing various custom ROM´s for about 2 months now, so I guess you could still call me a beginner. Recently it has been difficult to keep up with all the latest and greatest advances in kernels and ROM´s. Being a father I don´t have as much time as I used to, to read through the mountain of information on the forums.
It is for this reason that I ask for some simple advice. I have found that Hamster, Instanity and DocRom ROM´s are all very fine pieces of work and they are blisteringly fast. The GPS is fast, the themes are epic but alas the battery life is pretty bad (well for me at least).
I must admit thought that I am obsessed with my phone and I use it constantly to read the news, check emails and stream internet radio while I am driving in my car on a daily basis.
I currently have DocRom slim V3 installed after having done a complete fresh installation. But despite being fast it seems to be very hungry on the power consumption.
Do I need to cycle it through some complete battery discharge cycles and fully charge it, then reset the battery stats in CWM recovery? Does it need some days to settle? Or should I flash different Kernels and see which one gives me the best life? If the latter then which kernel do you recommend for JPU?
Thanks in advance!

Same here
With 3g my I9000 die after 10 hours!
With 2g die after 14 hours!
With data network mode deactivated die after 30 hours!
I don't know if changing baseband or kernel will help or not!

I'm having pretty good battery life without any network and LiveWallpapers turned off... just simple black screen it stayed ON for 4 days with some WiFi surfing, PDF reading and music listening player/online radio. So I guess network is draining the most.

DocRom V6.2
I just installed Doc´s ROM v6.2, and it has greatly increased my battery life.

Great to hear this!
I don't know if this is your case, I used to have the beautiful widgets weather widget on my home screen, and after soem time I realized this app was constantly refreshing and consuming LOTS of battery.
If you have it, removing it will increase your battery life too.

I have same problem,i do have the beautiful weather widget installed and think it looks nice on home screen,maybe this is the batt killer??
What other programs does the same? I like the watch and weather widget to be shown..?

[Q] Battery life has gone down the drain, plus lots of bugs. WHY?

I've had my captivate for over a year now, with mixed results.
Honestly i love the phone, and if i could work out my issues, probably can go another year without having to get a new phone.
My biggest problems are the battery, and the bugs.
When i bought my phone my battery life was ok. When i finally put a custom rom on and re-calibrated my battery, i would go as far as to say it was pretty good. (I even have a screen shot from the good ol days when i would go to work, and come home, and it would say something like - unplugged for 11 hours, and i would be at ~70 percent)
Now on an average day, i leave for work at about 630 and when i get out at 2 its usually down to 20-30 percent. I actually own 2 captivates and its the same case with both of them.
I dont understand what is different now from before. Ive actually tried the old roms which i got such good battery life from (serendipty 6.2 i think, and cognition) and still its terrible now.
I have recently used apex, cyanogenmod, miui, GR12, and maybe a few other, all with terrible battery and bugs.
Thats the next issue, the bugs are getting to a point where the phone is almost unusuable.
Many times google voice has just failed on me. Ill get out of work and see no texts, my data will work, so i figured theres no problem, but then ill restart my phone and everything will come in.
Im currently using apex, so thats my biggest problem with bugs, but cyanogenmod/miui were really bad.
Then theres the ugly, which is when my battery goes in super drain mode. Itll go down 1 percent every 2-3 mins sometimes, and the only way to halt the super drain is to plug it in for a few mins
I dont get what the difference is from then to now, but i was wondering if anyone else experiences these issues.
Maybe its the way im flashing or something, i dont really know anymore.
Any suggestions?

Have you seen which process/app is eating your battery? Could possibly be an app from market causing this

what is it you need from a custom rom? i've found i get the best battery life and stability from stock samsung roms, ie KH3. CM7 was wiped about 15 minutes after flashing.. it seems very experimental on the captivate, definitely no way i'd be able to use that as a daily rom

I had the same issue when i was using CM7. more battery drain on standby. Now i m using KH3, there is no battery drain on standby.
Try KH3 based ROM, if you are losing battery on standby

Well havent tried a KH3 rom yet, but i think apex is js7 based, which is an official rom.
I agree CM7 was very buggy, but ive seen the same with apex.
Honestly I used to get awesome battery life with cognition, and i reflashed that same rom, and now it sucks.
The only apps i have installed are:
adobe reader
beautiful widgets
colornote
docs 2 go
google voice
maps
pandora
screenshot
titanioum backup
zeam launcher
My biggest reasons for using a custom rom are:
tethering
adblocking
not as laggy (RFS)
screenshots
maybe a few more
I would glady give it up though if i could get some good battery life, and no bugs.
Am i better off just going back to stock jf6 and letting my phone update automatically?
Or should i try out a kh3 based rom? or just KH3 Stock?

i'm getting the best battery life from kh3. js7 is an i9000 rom that is not specifically optimized for the captivate so it may not be as good as kh3. regarding reasons for custom roms, i have all of that (except RFS) on the stock rom using these apps: adfree, screenshot er, open garden wifi tether -- all work great

Js7 is froyo.
apex is jvr gingerbread.
Both I9000 firmware.
Idk what you mean by "optimized for our device" but let me just say from personal experience that porting I9000, we don't just grab a firmware and theme it. There is coding to make it work. Plus I9000 has this thing called SOURCE CODE so that you can have a much more customizable kernel, instead of the time it takes to reverse engineer a kernel and then try to add things to it.
All in all custom roms will always be better than stock, because they take stock and improve on it. Also there is no such thing as bug free as every one uses their phone differently with different apps that may effect the phone in odd ways. You will have to just experiment and see what works best for you and your phone.

i don't see how a modified i9000 (J**) rom/kernel could ever have better battery life or general stability than a stock K** rom on the captivate. the way i look at it, there is a great value in having root on the phone, but not so much in having a custom rom. i just haven't stumbled on any rom that will give me a better experience than stock while at the same time keep the battery life. i've tried quite a few.
this is coming from a standpoint where battery life and stability are a priority

[ROM]Cyanogen Mod 6.3.8 - Massive Battery drain

Hi all,
I'm and oldbie that has installed allmost all the roms that avilable to milestone.
last one was ICS from kabaldan, wich i find it working very slow..
before i was at CM7 for allmost half a year and it was working good but not fast as all mantiond here..
than i moved to cm6 6.3.8.. Perfect Speed allmost, 0 stucks, stable and look nice.
but the batterry is draining like no tomorow..
i found myself with 10% Bat on the late afternon without and spesific stuff..
any sagustions?
thanks :>

Try turning off 3G in Mobile Networks. I believe this thing fixed this problem on my phone.

but when i was at CM7 the 3g was working non stop ..
why is there a big differance?

I have no idea, honestly. Did this fix the issue?

Nop this dident fix it..
the battery usage is on display (?!) and android OS (that i btw removed a few of apks that was causing battery drain on the android os menu)

Install CPU Spy from the Market and see whether the device is going to deep sleep or it's staying at the min frequency.

so ive been at this all day reading and searching these forums with no luck.
i have a droid one, running 2.2.3 FRK76, bought the phone used. says it has kernel version 2.6.32.9-g68eeef5. no clue what this is.
have tried to root with superoneclick with rageagainstcage option clicked. also tried the one click some one had posted on this site in one of the forums. Sd card is unmounted. debugg mode is selected. and i cant get past first time it says waiting for device. what do i do?

Also try better battery stats and see if an app is running a lot. Different phone, but I had save problem and it read google maps check in service. Also did you calibrate your battery it helps

[Q] Bad battery/browser etc

Hi All,
I see my self as a hobby flasher. I generally flash my phone 1-2 times every 2 weeks as I'm always unsatisfied by the performance/batt life.
Generally speaking I believe I have tried most roms. I like new project, well knowing that these often is not as optimized as the well tried roms that have been in "production" for many months. But I have some questions popping up, that I would like an answer to.
1. Is it only me, or has all Cyanogen 10.1 roms generally speaking a bad performance? I tried seveal performance kernels, but this rarely helps. If my phone is not randomly freezing, things like google now and chrome have problems. Either it is okay performance wise, or the batterylife is horrible.
2. Batt life. I have now had my note just above one year. Like 13 months or so. In the beginning the battery life was descent. On close to every XDA rom I have tried the batterylife is really short. Surfing on my phone for 1 hours eats a LOT of battery and my phone gets warm. Of cause the factory roms "knows" all the hardware secrets, and are able to produce an optimized rom, but until now I am to be positively surprised about battery usage in any user rom. Any advice? Recently I have disabled location settings/latitude etc, and this have helped some (obviously) but can it be that the built in google features take that much battery? Betterbatterystats confirms that google location services uses a LOT of juice. Are your experience the same?
3. Is the chrome browser that bad? - I use it mainly as I use chrome on my computer and I have all the book marks, but I think it keeps freezing. Generally speaking I think it is okay, but it is by far the app I use that freezes/FC most. Is your experience the same? What browser do you use?
4. What is your Rom/Kernel setup? It will have to offer good (maybe not great) performance, but will have to have great (not good) batterylife.
Looking forward to your replies.
-Benjamin

Anybody?

1. > on CM10.1 and battery is great, and very smooth.
2. > location services do use a lot of juice. i have it as disabled as well.., Notes battery doesnt seem to last more that 10-11 months.. lot of people were able to get good performance of new batteries.
3. > stock browser works best for me
4. > CM10.1 .. its own kernel... have used angry rom VT1 as well.. good..

[5.0.2] [Lag/Heat/Battery - Problems] How to fix those Problems?

Hello together I have startet this Thread in the ZL Forum as well but there are way more Z Users than ZL So maybe you guys can help me too? first my specs:
Model: Sony Xperia ZL C6503
Android 5.0.2
Build: 10.6.A.0.454
Kernel: 3.4.0-perf-g8fa3dae [email protected] #1 <- Vanilla Kernel I beliefe
Root: Yes with kingroot following this HowTo Link I now got SUperSU 2.46 installed
Bootloader: Locked - I didnt unlock it and I think the rooting didnt unlock it either
Apps: ~95
I have the following problems:
1. Ever since 4.4.4 my Sony ZL is somewhat laggy. With 4.4.2 I had a really smooth experience but since 4.4.4 its been a dirt road. I am happy that Sony still brings us the newest updates with Andorid 5.0.2 and soon 5.1 but I hate that my user experience drasticly decreased. Not only do games lag since Lolipop, now the UI interface is lagy and my browsers (Dolphin with Jetpack) lags. Its just a big **** up! Its not smooth anymore and it doesnt make fun to wait several seconds (3-5) before apps open or close. I have no longer any task killer, with my last it felt to decrase performance instead of increase.
2. I have a heat issue with the phone somtime it gets really hot really fast.
3. Battery doesn't hold a whole day anymore. Could be casue the phone is 2 years old already but sometimes I have really bad battery life. If I turn on GPS I can forget to use my phone cause battery dies within 3 hours and apps just collapse under the heat.
I have Stammina tunred on and @30% Low Battery kicks in. @15% Battery saver tunrs on.
Battery drops from 12% -> 0% and turns off phone. Sometimes I get to 8% and then 0%
I would like to fix those issues and I need your help and advise. Yesterday I was almost to the point where I threw my ZL out of the window but I decided to give it a last chance with some help of the XDA community. So for my phone you are the last chance otherwise I will throw it out.
My Problem: I dont really want to completly start fresh and install all apps and configure everything again. I have Titanium Backup insallted (but I dont really know how to use it). If I have to completly start fresh I will probably get a new device casue there I will have to do the same legwork anyway. Only if money is thight next month I will stay with the ZL and do it all over again.
So can you guys help me to fix my problems? My biggest problem is the lag issue. I can life with the allright battery life and the heat issue but the lag drives me insane.
Edit:
In the past I already tried to root my phone while I had 4.4.4 but at the time there was no root available yet and some tasks failed. Not sure if that had any impact.

You could try to change the gouvenor of your CPU. I use interactive. It saves battery and the phone doesn't heats up so much (its still really hot sometimes). You Phone also becomes more efficient, because it only clocks fast if you need the power. You can do that with the PACPerformance Application or Antutu CPU Master as example.
If the interactive gouvenor doesn't helps, you can still try performance, this will give more power to your applications, but degreases battery life.
The heat comes from the old Snapdragon S4 Pro Processor that needs to clock most times at the maximum clock speed and it has no real thermal throttling. One time my Phone was at 100°C. Then the Android Operating System started to shut down the phone. The screen also started flickering.
After you got the 5.0.2 Update your Phone should feel much smoother.

maybe can with lollipop 5.1.1 :angel:

Hi I will try that! Thx for the answer.
