[Q] Most stable custom ROM avail

Hi all,
I know most of you guys use CM7 RC0 But I just want to know which is the most stable custom ROM which has all the features avail and no FCs or ANRs?
I almost tried all the ROMs including Stock Eclair, Froyo, CM7, MIUI, China Unicom etc. Currently using China Unicom 2.10,
My main concern is about battery coz no matter which ROM i use I get only a day of battery life :
So I'm looking for a Froyo/Gingerbread ROM which gives MAX battery life, supports HD video recording, fast and stable. Of course Ill stick on to CM7 once the official version gets released.

I am also looking for a rom with good batt usages n smoothness will wait untill any1 rreplies

for good battery life, please keep the 2G on, and switch to 3G only when needed. this is probably the best thing you can do for your battery life. also, make sure the baseband is correct for your usage. however, only you will be able to do this yourself. try a few until you hit a good one.
cheers!

Well.. Of course I always follow the tips to conserve the battery like setting to 2G, very few animations, setvsel to undervolt, not many widgets. But still I get around 1 to 1.5 days of backup.

I have been using CM7 beta 6 for a few weeks already and it has been pretty stable. Lasts around 3.5 days with moderate use. Heavy use( a lot of phone calls), around 1.5 - 2 days.
Just make sure that you select the correct baseband.

Yes, I install the correct baseband everytime I change the ROM, I'm suspecting my sim might be the culprit which is not letting the phone to go to DSM. Ill change it and see..
How stable and cool is Pays rom???

If you can get through a full day with the "micro laptop" we now refer to as a phone, you're in good shape! Plug it in every night and be happy.
If your particular usage patterns don't get you through a full day, or if you can't plug in every night, there are plenty of extended battery options available.
You guys need to understand that the manufacturers are forced to decide between battery life and size/packaging. Today's phones are designed to be practical for the average consumer who is able to plug in/recharge their phone every day. And fortunately, the aftermarket offers us the option of getting longer battery life in exchange for a larger package (ie 3500+ mAh batteries with covers)...

Well, You are right.. But I'm very Jealous that many people get 3 to 4 days of battery backup on an avg usage, I have seen posts where they mentioned 6 days of battery backup using the china unicom's rom, So I flashed the ROM hoping Ill atleast get 2 - 3 days of backup.. but even that didnt help..

Turn off your data connection and any automatic syncing. Your phone will go a full week if it just sits there sleeping the whole time ;-)

[Q] ROM with best battery life...

Hi, just wondering if someone can tell me which ROM is best for battery life. I'm currently using blendkernel, is there any particular combination of kernel/ROM/baseband etc, not fussed about overclocking, just purely want it to last!!
Thanks

From my personal experience, the stock rom is the best for battery life, though I've switched to using arconium since it's just a tweaked version of the stock rom.
There's a few out there (that are just a tweaked version of the stock rom), so take a look in the development section and find one you like.
Using the stock kernel sometimes makes a difference as well (it did for me) so you might want to try that as well.

For me, using blendkernel, the ROM that optimizes battery and is 100% operational, is 【ROM】【LT15I/18I】Xperia_AniKing_v1.0.0_Ice Cream

for me till now i used only one room it's MIUI and till now it's fine

Ok, thanks for that, I'm going to give the Aniking ROM a go and see what happens...

Can the blendkernel (original for MIUI) be used for any other ROM? Like stock ROMs or even CM7?
I always thought that blendkernel can be only used for MIUI based ROMs....

I'm using the kernel from this thread
http://forum.xda-developers.com/showthread.php?t=1278760
Seems to work fine with most ROMs and I've found the battery to be much better than using Doomkernel...

Hi,
Just a few days ago I've installed the Miui rom on my lt15i as posted on
http://forum.xda-developers.com/showthread.php?t=1528924 with the 2.6.32.9-BlendMIUI kernel by Jason Stein. However in these few days my phone has to be charged every night after being unplugged for about 20 hours.
Today in 16.5 hours my battery has dropped from 100% to 15%. Most of the time the phone is in sleep mode and I've measured that the battery drained about 3-4% per hour while in sleep mode. The phone synch with 2 google accounts in the background and the screen brightness is set to 25%.
For the rest I've made a few short phone calls (about 10 minutes of total talk time), browse the internet for like 15 minutes on the internet forums and played about 10 minutes of Coindozer.
Is this kind of battery life normal when running the MIUI rom on the BlendMIUI Kernel? In "Battery use" in "Battery settings" I got these stats:
Cell standby: 42%
Voice calls: 21%
Phone idle: 10
Display: 9%
Wlan: 5 %
Opera Mobile: 4%
Android OS: 4%
The rest are just about 1-2%
Seems like I'm better off with the stock rom as most of the time I can get about 30 hours using the phone before having to put it on charger. Now I can only get about 20 hours
Anyway I would be happy if anyone can give me advise how to get more battery life out of my phone while using the Miui Rom, cause it's working quite neat in my opinion and looks very polished.
Regards,
Albert

You can try to undervolt cpu supply if your kernel supports this feature.
Also try to flash baseband libs (only for -36 and -64).

I prefer the stock based roms.. I personally like the XperiaMod but I have been using Arconium 8.0 from last 4 days and its battery drain is just awesome!
If u wanna have an ICS one, simply flash the KA 10 Ice Cream Sony.. Simply the most stable and best ICS rom till date!!
Hit Thanks if I helped u..

I recommend Arconium 8.0. It is basically the rom your phone came with, but it's a tweaked version of it.
I also found Miui battery friendly. I've been using DiMiui for a couple of weeks now, and I can't complain.
Sent from LT18i @ Xda Premium

Well, I just got hinted that it is possible my battery needs to be recalibrated. Last time I flashed my rom, my battery was not fully charged. I've looked up on internet and indeed some articles states that everytime you flash your rom your battery have to be fully charged to avoid this kind of trouble. I'll try recalibarting my battery.

[Q] How to take my SGS2 completely to stock ICS

I upgraded my stock rooted GB SGS2 to ICS with Kies on the 12th. Battery life has been awful compared to what I got on stock GB (15-18 hours with normal use) I'm now losing about 10% an hour just sitting idle. If I use my phone at all it won't last 8 hours before the battery is at about 10%.
I did a factory reset and re rooted two days ago and I made it about about the same amount of time before the battery was almost dead again. Last night, I did a factory reset and flashed T989UVLE1_T989TMBLE1_T989UVLE1_HOME.tar with odin then rooted and still about 8 hours after I took it off the charger it's at 20% and I've barely even touched it today. I do not have any apps or widgets installed that I didn't before on GB. I didn't restore the apps with Titanium Backup, I manually downloaded each one from the Play Store. I've wiped the cache and fixed permissions in an attempt to get S-Voice to stop crashing.
Another problem I have is issues with bluetooth routing calls through my cars bluetooth. When it is paired my notifications skip and sputter when they go off.
To the best of my knowledge when I Odin'd back to stock ICS that wiped everything out but since I had an issue with my old Vibrant having remnants left over when flashing ROMs I'm wondering if this could be a similar issue. I usually flash with CWM and not Odin Is there something I should be doing to completely wipe everything out and go to stock ICS? Most all comments I've seen say battery life is even better than GB. Mine has gone the opposite way. Help?

Download TDJ's superwipe (theres a thread for it in the dev section) and run it, THEN Odin the stock tar file.

Thank you!
I notice it says after doing to the super wipe to stay in recovery and flash the ROM. Should I find a flashable zip of ICS or is it ok to use Odin after?

I flashed the zip and went ahead and went into download mode and odin'd stock ICS. Google is actually restoring my apps this time...it didn't the first three times so, so far so good. Thanks for the help.

10 hours with very little use and battery us at 25%
Sent from my SGH-T989 using XDA

D2H, Question for you... You're rooted, have you tried calibrating your battery yet? The only reason I ask is because I was stock unrooted when I upgraded to ICS and my battery life too sucks BIG TIME. Maybe 5hrs, 6 definately tops. I even tried factory reset (which is questionable), removed the battery, let it drain completely and then pulled the battery again and full charged. Still on pace for 15%+ /hr. with light usage.
When I rooted my Sensation I used a battery calibration app and that improved my battery life by leaps and bounds.
I was thinking of rooting my SGS2 just for this.

No, I've not tried that. I used to do it with my Vibrant and never really saw a big difference. I also saw a post here somewhere on here stating that calibrating the battery was a myth.
I may as well try it though. Otherwise I'm going back to GB as this battery life is unacceptable.

D2H, so whats the status?
Myself I finally bit the bullet and rooted (OMG SO SIMPLE compared to HTC). After rooting I downloaded "BatteryCalibration" from google play (Same app used on my Sensation). After a full charge yesterday, I calibrated...to TRY to drain my battery down completely for the next charge I turned on BT and GPS. This all happened around 8pm last night... Well its 5:08pm next day now and my battery (with BT and GPS still on) is only at 68% now and that's after some surfing, video watching, games.
I have to say give this a try before going back to GB.

Come to find out there was a beta release of HD Widgets that downloaded when all of my apps restored. That was the culprit. I'm back to 16 hours of battery life.

Cool! It's going on 10:30 pm here and my bt and gps are still on and I'm at 29%... This includes more Internet browsing, games, phone calls and Txt msgs. No charging since yesterday. I won't be surprised if it's still on tomorrow morning.

Chronic battery issues with a variety of ROM's

Hi,
I've searched through various threads here and in the development/ROM forums but need some advice and didn't find advice for my specific scenario.
From Jan - Sept this year I was rooted but running the stock 4.1 Android (Rogers), I tried CM10 and a few other custom ROM's but eventually went back to stock carrier TW, with the only root change being the 4.2 Camera (for Photosphere) being installed (via CMW). During that time my device ran pretty ok in terms of battery life.
Then in Sept I started getting serious battery drain issues. I've got a few extra batteries and an external battery charger so I ended up swaping in and out charged batteries twice or three times a day.
So I decided to re-enter the root world and have since tried a variety of ROM's to see if the battery issues might be fixed. Installed TWN recovery rather than CWM, Tried ROM's such as Task650, CM10 Stable, CM10 Daily, and I still am encountering pretty dismal battery life?
I've tried various battery apps and generally keep screen brightness to a minumum, turn off mobile data, and have wifi/gps/bluetooth/sync off for most the day
I can't imagine it's the battery themselves, 1 is the original that came with my GS3 last year, 1 is official Samsung bought a few months ago and two are Anker ones that worked fine for months.
Can anyone recommend a specific ROM that may have worked for you? I haven't really messed around with custom kernals much, only played with kernals and governors a while back when trying out SETCPU (which I havent used in ages).
Any ideas?
Thank You.

Try the app BetterBatteryStats and see what is using up the battery. After a few hours of having the phone idle, look up the process running on the phone that uses the most wake locks.

Hi,
BBS did not really reveal one glaring thing draining the battery while the screen was off.
Any other ideas?

Battery Life TERRIBLY sucks

My battery life on 4.3 stock was 8 hours screen time (half brightness I believe)
Rooted and flashed a custom rom and kernel 7hr30min screen time
Flashed different kernels dropped to 6hr max screen time (without factory reset)
After installing Xposed and many many modules the screen time kept dropping to like 5hr to 6hr
Updated to KitKat and rooted 4:30min to 5 HOUR MAX screen time PLUS phone got hot ALOT OF TIMES
***RIGHT NOW*** Flashed a custom ROM HyperDrive with Colonel X latest and Compulsion latest BOTH 3hr30min to 4hr30min MAX screen on (EVEN with Jovy23's kernel settings that got him AMAZING battery life with ConservativeX governor - It still did not fix the issue not even a little - I still like Compulsion which was awesome when I was on jellybean) :'(
Same settings for all the above set ups. Whenever I flash a ROM I ALWAYS clean flash and I DO NOT have Titanium Backup NOR do I use any other restoration app. I tried to clear and format every partition. I formatted SD card. SAME issue. I am frustrated by the battery life; it DOES NOT last me a day when on stock unrooted it was easily 8 hours. Also I do not use auto-brightness cuz the sensor uses more battery, so it was on half-brightness)
Someone please help me. The worst thing about a phone is the battery life. I usually browse Chrome and Facebook and for these simple tasks my battery dies quickly (WTH?!). I can't even think about gaming (and I REALLY want to GAME), but I know the battery life would die so much.
Is my phone defective? I tripped Knox. I already had a warranty replacement in like the first 2 weeks cuz of Knox issues stock. WTH is wrong with my phone. I want to format and clean EVERY SINGLE THING on my phone to get it the 8 hours screen on time I used to get. No matter what I do my battery life right now WILL NOT go above 4hr30min to 5hrs screen on. I used to watch Netflix for quite a while back on my stock Jellybean / rooted Jellybean days, now it dies extremely fast.
What should I do? I was thinking of flashing AOSP so it cleans up whatever Touchwiz and Samsung related is on my phone and then re-flash touchwiz so everything is set up correctly. I tried to use the mega-wipe script for a certain Note 3 model but it stopped at like 10% to 20%, so that route did not go well (I manually wiped everything data, internal, etc, before flashing many ROMs and this problem persisted).
I cannot do anything good on my phone until this issue is fixed. I hate clean-flashing and setting up things (I think titanium backup and stuff screws up your system) all the time. I cannot game, I cannot download good apps, I cannot do anything that is not online based or can be backed up online. Apparently my battery state is stated as "good" on the system.

"... All of this in under one day..." Give it a few cycles over the next few days. It'll change. I've been using HyperDrive with ColonelX with the conservative governor tweaked for performance. Can't really say much about the battery life since I have the 10000mAh battery.

Dude, if it's all under one day. You need to let a ROM and kernel set In. You can't drive a car without wheels. Just give it 2 or 3 days it will begin to get better. That's what I think too but I give it some days to stabilised if you will . Then my battery goes from normal to good to great. It won't right away start getting great battery life. Unless you have a kernel your phone don't like and flash another it does like battery life improvements where almost instant at least in my case. Like now I'm getting Ok battery life. It's not the best. But it holds. I might switch kernels tonight to spice things up.

I meant the right now part is under a few days. Idk why i said all under one day (it was late night). This has beena problem since February at least
Trust me I know you have to let a ROM and Kernel set in but my phone keeps working harder than its supposed to. Screen off battery is good, so wake locks are not the problem. The problem is cpu wise something is messed up that it puts my cpu to drain huge amounta of battery

Even you tried another or different ROM still happens?

The rom and kernels might be the one messing your battery life, since your battery is in good state, but why not try replacing a battery if you have an extra and see the results...

How do you find that out?

There is an app that can report this value. The premise is that certain cpu's have different values which indicate how the cpu will perform. The problem is, the same cpu can over time end up reporting different values which pretty much means it is not really a set hardware value and most likely means nothing.
You can find the large thread about it if you look, but it was pretty much debunked as a really value at the time.

first download the new rom http://forum.xda-developers.com/showthread.php?t=2709867
put it on a sd card
make sure you have a custom recovery
1 go to setting back up and recovery do a reset from there
2 let the reset be done then restart the phone and go to recovery
from recovery do a full wipe factory restet
3 install the zip from the sd card
4 pick the apps you want with aroma installer and install compulsion kernel
4 finish installation and boot up
set up the phone and enjoy it bro.....

Nice battery life enhancer.

You have to let the rom settle before you can get accurate battery life akin to the rom and kernel. Trust me I know this as a fact. I have been flashing roms like crazy since the days of the Samsung admire and the rom takes days to settle.

I have the same problem. 4.3 battery life was 6 hours screen time, 4.4 down to 3 hours screen time. Note 3 used to be my ideal, perfect phone. 4.4 ruined that.

You made sure to toggle allows allow scanning off?
Toggle either power-saving or GPS only under location?
Power saving mode if applicable?
Turning of haptic feedback?
The always allow scanning seems to be the number one battery killer for me. I turned that off and noticed immediately better battery life. Almost akin to an extra minute per one percent, which adds up.

Yep, did all that stuff from day 1 back on 4.3. Updating to 4.4 was the most frustrating thing ever. Many people here report great battery life with 4.4, but many like myself had it slashed in half upon upgrading. It ruined an otherwise perfect phone.
