Problems common to all Froyo based Milestone ROMs?

Can anyone say what are the common confirmed bugs of 2.2 leaked kernel(s) for the Milestone? I'm trying to figure out if I should stick to Eclair based ROMs until official Froyo comes out because I need a reliable phone that won't die on me in the middle of the day, although I've charged it that morning.
So, what are the common problems of 2.2 ROMs? I've tried searching but everyting's scattered around, I couldn't find all the problems listed in one place.
So, I heard of:
1. Phone not going to sleep, thus draining the battery excessively.
2. Phone not charging to 100% (fixed in latest kernel leak).
3...?
Are there any other confirmed bugs?

1. Not true. Phone does go to sleep.
Everytime after charge, when unplugged, it is better to reboot the phone and you'll know for sure your phone goes to sleep.
It does go to sleep many time without reboot. You can check this on "Spare parts" "Battery History" and there you have "Running".
If "Running" shows "100%" means you should reboot in order for you phone to go to sleep.
Actually battery life is pretty good on 2.2.1. The most I got from it was 60 hours with medium usage. I'm using latest CM6 and I'm pretty satisfied.
For better performances and when you are switching from one ROM to another you should remove:
/data/system/batterystats.bin
2. Yes. That problem was fixed with these latest releases.
Hope I've been helpfull!

Battery performance across ROMs

Hello all-
I wanted to start a thread to discuss battery performance across the various ROMs available:
1. Nookie Froyo (including NookieComb based on Froyo)
2. CM7 (Latest build)
3. Rooted stock
1. What ROM do you guys use and how is the battery performance?
2. How do you maximize battery performance? Kindly list the settings if you can.
Thanks,
mg

Phiremod is completely based on CM7,it's just a themed version. So I actually doubt there's any difference.
I have a question too. Has anyone tryed battery calibration? I'm not sure this app supports tablets though.

I never tried it but that would make only your battery readings more accurate. IN CWM its also possible to recalibrate i heard. Never tried it though.
Most ROMs have allready been tweaked pretty much. I'm on Nookie Comb (2.2) however just because there is still a bug in gingerbread (w/ or w/o CM7) preventing 'deep sleep'. So the device is still active when you press the power button. That cost me about an 2% and hour equals 48% in a whole day. (just idling). They (devs) are looking into it ATM.
Honeycomb preview also has the deep sleep bug.

In the past, I've just cleared the Battery Stats in CWM when flashing CM7. Be sure your battery is fully charged for the most accurate readings.

Ah, that's why CM7 drains battery. Did not know about that bug. Hope they fix it soon.

I did an over night battery test with only the released CM7 on the SD card and it was draining about 0.8% per hour using the built in battery meter. I don't know how accurate a test this is but the result was better than the 2% drain that I saw posted else where.

[Q] MIUI ROM doesnt go to sleep!!

Hey All,
My Milestone running MIUI 1.6.4 doesnt go to sleep when I turn the screen off. This is leading to poor dormant battery life. The battery drops by about 10 percent for every 1 hr, when the phone is not in use(ironic, cos when the device is actively used, MIUI seems to have the best battery life). I checked the built in battery usage chart, and the thread that keeps the device awake is Android System itself. Is this a known issue? and are there any solutions available?

Had same problem!
Had exactly same problem a couple of months back and posted question here but no response.
I was able to initiate deep sleep but had to do various things such as reboot time after time until successful, open up a variety of apps, use a task killer, etc., to try and resolve problem.
I was using CM 6.0 initially and even updated to the latest update of that build by wiping everything but all to no avail. I was beginning to think that it was a hardware problem when I flashed an entirely different rom - MIUI 1.2.25 and hey presto problem resolved.
I suggest that you may have to do likewise and try another rom entirely. BTW the battery life of 1.2.25 is very good indeed. I also recommend using CPU Spy found in the market and/or CPU Stats found in the Themes/Apps section of this forum to monitor deep sleep status.
Hope this helps

[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

[Q] Good kernel/rom combination for me?

Hello,
I'm currently running:
Slick2x-F V4.5 (android 2.2.2)
+
HTC Sense 3.0 theme
I'm not sure about my kernel, I haven't flashed it but one of the roms I used might have flashed it, not sure.
I'm looking for a good rom/kernel/theme combination which looks good, performs well and maybe the most important thing, gives a good battery life. A good battery life is about 15-20 hours with about 2-4 hours of heavy usage in those hours. I currently get around 14 hours using the phone heavily for around 3 hours a day.
The current combination I was looking at:
ROM: http://forum.xda-developers.com/showthread.php?t=1254359
Kernel: http://forum.xda-developers.com/showthread.php?t=1295486
Theme: http://forum.xda-developers.com/showthread.php?t=1178640
Will this get me good performance + battery life?

I can tell you one thing for sure: any GB based ROM will be less easy on your battery life, it seems like Froyo releases are better are that, ATM.
I am currently using Topogigi's ROM, with SP 1+2+3 applied, and have just flashed HP kernel SR1 so it is too early for me to say anything on battery life; beware, though, that the latest HP kernel has a very strong vibration even in haptic feedaback and this in my case messed with the 'tap side' gesture to move in between your text... I had to disable this feature or the cursor would keep randomly jumping to the left.
If you are looking for best battery life, stick with Froyo: using stock v10d I managed to use my phone for two entire days with light usage.

Thanks, I'll keep that in mind

for me, i use GR4 modaco(v20j) 2.3.4
Code:
http://forum.xda-developers.com/showthread.php?t=1181407
and the kernel i use neoblaze
Code:
http://forum.xda-developers.com/showthread.php?t=1200726
the combination is good, i get 6452 score on antutubenchmark(oc 1,4GHZ), and it's still using ext3
you can use horsepower kernel from spica check the development section. i think it's pretty fast support ext4 (haven't tried to flash it) and it's already stable release
Code:
http://forum.xda-developers.com/showthread.php?t=1295486
or you can use CM7.1 it's 2.3.7 and the function like bluetooth audio & fm radio already functioned
or miui or any other rom in the dev section. have fun flashing

I'd say that the most stable rom is topogogi 2.0 + all the 3 sp's.
Combined with the sr6 kernel from spica it is very battery efficient (About 1 day
and 14 hours with light usage).
If you want to get a lot of juice out of your phone then get a froyo ROM.

Just wait a few days untill v20l roms start popping up, they probably have increased stability + battery life

They don't... They only updated the ROM not the kernel so the kernel should drain the same amount as it did before (and from my experience that kernel drains a lot!).

I vote for MIUI 1.10.28+Owains tweak pack (with swiftextreme)
