[Desire HD Q&A, Help & Troubleshooting] AndroHero:
An easier way would be to do a nandroid, if it goes wrong, just use the advanced restore, to restore /system. But i have been flashing kernels from recovery since i got my hero and have never had any issues......
[Desire HD Q&A, Help & Troubleshooting] suddy86:
Out of interest, what kernel are you planning on flashing?
[Desire HD Q&A, Help & Troubleshooting] AndroHero:
The leedroid v.2.0.3 kernel i assume lol
[Desire HD Q&A, Help & Troubleshooting] suddy86:
Doh! Missed that one, lol :o
[Desire HD Q&A, Help & Troubleshooting] gabryice:
Hi folks!

I have n answer about updating kernels..

I'm on CM7 actually and I have flashed a modded kernel, if I go with an update of CM7 does this overwrite the custom kernel and I have to flash it again?

Sorry for bad english. :)
[Desire HD Q&A, Help & Troubleshooting] seelinkit:
thanks guys, i finally flashed the kernel (taking the risk cause i forgot to do a nandroid) luckily i did it with success. thanks for people who answered my question. more power to you guys
[Desire HD Q&A, Help & Troubleshooting] AndroHero:
if you flash a new rom, you will get whatever kernel comes with the rom, so yes maybe you will :)

Can anyone help me?

[GT540 Optimus General] MomirPeh:
Hello everyone!

Since I'm a newbie to this forum, I can't post in dev. branch, so I'm posting this here.

Yesterday I flashed Mur4ik's newest 2.3.2 Android ROM and I'm most satisfied with it, apart from the heavy drain on the battery. I'll try to solve that problem and post the results here. My main suspect is the Cyanogen's CPU OC control in Settings. Here's why...

Yesterday in the evening I charged the phone to full and left it on the table overnight. In the morning my battery was at 55%!!! Immediately, I went and checket CPU clock times in Android System Info and percentage of time the phone used max CPU speed was over 50%! So, this morning I installed SetCPU and used the same settings I used with the built-in CPU speed setting tool and I manualy set the speed to be min. 245MHz and max. to 806MHz. Then I added a profile for "screen off" to use min. 245MHz and max 245MHz too. I think this could be the solution, but we'll see.

I'l keep u posted!

Cicko
[GT540 Optimus General] panoramixus:
I'm kind a notice it myself. When update to new 2.3.2 without OC battery last for two days with heavy using and after OC to 806 Mhz its one day.
[GT540 Optimus General] MomirPeh:
I'm already seeing improvement with SetCPU and screen off profile! CPU time spent at 806MHz is rapidly decreasing in favor of 245MHz --> Battery drain slowing down proportionally! And the phone is responsive as ever.

I'll keep track of it in the next few days and post results.

Greets!

Mur4ik, thanks buddy, for an excellent job so far! ;)
[GT540 Optimus General] shaunb84:
Thanks for the info, hopefully we'll be able to sort this out.

I'm living on battery fear land now
[GT540 Optimus General] Shavi:
ill try it... i got the same problem with cyanogenMod 7 ... when i was with official LG Eclair.. battery was great...

cyanogen extremly drain my battery life...

when im chargin it.. some time it stucks at random percent... sometimes stuckst at 50 % , 70 % :S
[GT540 Optimus General] MomirPeh:
Update:

My battery life improved, but not as expected...

I didi a little research myself and found out that there is a similar/same problem on other Gingerbread ports for other phones. But, people there are saying that they have problems with sensors daemon (akmd2) which is using more CPU than it should. I noticed almost the same thing on my phone. There are two possible fixes proposed by some people:

- First is to set a huge polling delay for akmd2 which reduces responsiveness of orientation sensor and compass. It's done like this:

adb shell

echo 250 > /data/delay

- Second option is to rename or move the akmd2 binary from /system/bin, which would turn off the orientation sensor and compass.

I don't like these "fixes", since they are disabling some of the main features of the phone, or rendering them almost unusable...

I'm considering a downgrade to openswift 4.4 untill this is resolved...

Another thing I noticed is in the logs. When the screen is turned on there is a error message regarding sensors which could be preventing the akmd2 process from working properly and thus draining the battery. Log entries say:

I/power (1266) *** set_screen_state 1

E/Sensors (1266) read_sensors_state

Edit #1:

I checked logcat on my friends HTC Magic and it says (when screen turned on):

I/power ( 144): *** set_screen_state 1

D/AKMD ( 110): Compass OPEN

D/Sensors ( 144): sensors=00000001, real=00000001

Edit #2:

I restored my previously backed up OpenSwift 4.4 (Android 2.2.1) ROM and from logcat i see this when screen powers up:

I/power ( 1151): *** set_screen_state 1

D/Sensors ( 1151): using /dev/input/event3 (name=compass)

D/Sensors ( 1151): sensors_data_open: fd = 99

E/Sensors ( 1151): sensors_control_activate active=00000000 sensor=00000002 new_

sensors=2 changed=2

D/Sensors ( 1151): open_akm, fd=101

D/Sensors ( 1151): sensors=00000002, real=00000006

After seeing this it seems to me that in SwiftDroid 1.3 sensors stay ON (they all work normally when needed) even after screen goes off, so that could be the main problem with battery drain.

Anyone pass this to Mur4ik, please?
[GT540 Optimus General] MomirPeh:
Never mind, I got the post count to 10... :D
[GT540 Optimus General] Shavi:
I used set cpu in cyanogen and the battery life were improved a lot.. mie i can use it about 1 day. I hope cyanogen moders can fix this problem asap.

Battery problem

Hi 540 maniacs :D

After i flash it my 540 with CM 7 2.3.2 battery was alright for over 2 days and I was surprise that is so good but then after recharged; phone discharged in 8 hours (LOL?). So I started look around WTF and SetCpu profile for screen off + Auto Rotation Off and that cause my phone have 60% of battery from 18/02 5:50 AM. So it could be sensors as well draining battery ehh hope for quick fix.

Peace ^_^
[GT540 Optimus General] RATOz:
I don't user overclock, then I use CPU tuner.
[GT540 Optimus General] despotovski01:
With SwiftDroid 1.4b the battery life is increased. Try it.;)
[GT540 Optimus General] MomirPeh:
I am trying it already and it's great so far!
[GT540 Optimus General] Dr.Alani:
1.4b is better but still draining too fast as compared to the stock 2.1.
[GT540 Optimus General] MomirPeh:
It's doing well for me. I just had to disable the built in overclocking app and use SetCPU with speeds 245-806 MHz (ondemand governor) and a screen off profile with 245 min/max speed and it works like a charm! No more meaningless battery drain.

If anyone has a better profile for SetCPU (more efficient) please share it with us!
[GT540 Optimus General] SrkeeOSK:
how you disable cyanogens utility OC?
[GT540 Optimus General] Dr.Alani:
Sorry for re-posting from the general forum

I am having some trouble with the 2.3.2 by Mur4ik. The problem is when I closed an application like K-9 Mail of Facebook or whatever, it takes about 20 seconds to reload the android home screen. During that time I get only the wallpaper and I have to wait to load the shortcuts and widgets.

Another symptom is when I move from and application to another without closing the first one, and then I go back to the first one through long press on home button, I find the application restarting.

For example if I am at the opera browser and I press home and open K-9 mail or a notebook app, and then long-press the home button and choose opera I find the page gone and it says loading, just like starting the app all over again.

This happens with all apps not only the browser.

Is this because the memory is simply not enough so the phone kills everything not currently active?

or is it a bug in the OS that needs to be looked into?
[GT540 Optimus General] MomirPeh:
@SrkeeOSK:

I just unticked the option in overclocking "set at boot" in Cyanogen's settings menu. Then installed and configured SetCPU as normal.

@Dr.Alani:

Maybe you haven't flashed properly, maybe Your SD-Card needs to be reformatted... Try to follow the exact procedure for flashing the rom (wipe first with "fastboot -w"). make sure that You don't touch any settings if You are unsure of what they do!

Good luck ;)
[GT540 Optimus General] Dr.Alani:
Apparently there was some app killing the launcher automatically. I looked into it after a friends advice over @modaco and foound that the app "super manager" has an autokill thingy in its widget.

Uninstalled it and testing now.
[GT540 Optimus General] crzy_frg:
First time I flashed my 540 with CM 7 2.3.2 battery lasted alright for almost 2 days buty after that it hardly lasts 20 hours with implementing all advice to increase battery life for this ROM. Definitely in this ROM the battery is not charging to full and OS is reporting wrong percentahe during the charging and discharging. Any one found the reason why it is and how the wrong % can be corrected. As soon as the OS reports 100% phone stops charging the battery.
[GT540 Optimus General] somoant:
I had (1.3) problem with battery too, i did battery format:

1. full charge battery (when is full, unconnect charger, and then connect again, i did it twice)

2.wipe batery stats

3. normal use (1,5 day - without usb connection!!!)

4. at 5% i try to discharge battery completly (turn off and turn on, again and again until device start)

5. then i charged to full (unconnect charger, and connect it again)

6. normal use (3 days - without usb connection!!!)

7. at 5% charge to full

8. normal use 94 h (alamost 4. day)

normal use by day: appr. 1 hour call, sync on (edge/hspd), mailing, every evening at home wifi switched on, i am not using oveclocking, i don't play games, gps active only once for 1 hour walk, instaling apps a lot, for datatranfer bluetooth (to prevent be charnig from usb)

Percentage looks more accurate too, after charging 100% is for 30 min, then fall down to 95, and slowly to 75, then very slowly to 5% (before fast to 50% and then stuck there, and then fast to 5%)
[GT540 Optimus General] crzy_frg:
Thanks somoant, I am travelling right now but will try this out as soon as I can. Will update on my results here
[GT540 Optimus General] somoant:
ok, i will be glad, we must resolve this mysterious battery behaviour,

some people have problems, some not, maybe there also some settigs whose influnce battery life, maybe way of use, maybe...

I had problems with battery already at 2.2 rom, after this format = now,

i have 4 days without problem.
[GT540 Optimus General] m4rtijn:
I'm still on 10 hours with wifi enabled.

Now at step 4.. how long did you do that? because I'm decharging now 15 minutes (on off on off on off) :p
[GT540 Optimus General] somoant:
wifi enabled but i don't mean it was using whole time, i just enabled it, in sleep-screen off mode wifi should disabled, you can check it by ping phone ip from pc

4. sorry for this 5%, just bring phone to to state it turn off by itself, you should try turn on everything (gps, wifi, scree...) until phone turn off by itself, then turn on, but device should turn off by itself, i was just turninig on phone, until completly death (maybe 20-30 times)

after this all i don't think, mur4ik rom has battery issue, maybe can optimalized, maybe there some settings, apps, etc, which can drain battery faster, but not rom itself

maybe this can help:

Using 1.4b:

8 hours for me on the 2nd charge,don't know why,the first one was very good (1.5 days). I'm using a 122/844mhz with cyanogenmod options (uninstalled setcpu after thinking IT was the problem)

Random % during charge here too.

Edit: i noticed that Maps continue to start as a service. When i kill it after some time it loads again. It's the first cause of power consumption on my GT540,as i can see on the battery statistics. Any idea?
[GT540 Optimus General] somoant:
some people on 4pda claims that cyanogenmod options drain battery faster as setcpu, they recommended using setcpu instead of cyanogenmod options.

but i can't confirm it, 'cause from 1.3 version i am not using overclocking (standart min 245, max 600)
[GT540 Optimus General] Eth4n:
What can happen if i remove the cyanogenmod options using the uninstaller? :D
[GT540 Optimus General] somoant:
i have no idea try:D
[GT540 Optimus General] Eth4n:
As for Maps issue,i found this:

h**p://code.google.com/p/android/issues/detail?id=8247

I'm not alone lol :D
[GT540 Optimus General] Dr.Alani:
I hope this issue get solved in the 1.4RC version. I am back on the 2.1 because of it. :(
[GT540 Optimus General] crzy_frg:
Seem to worked for me on 2.3.2 with moderate use and overclocking now lasts 24 hrs wkthout USB connection and yes couple of hrs of wifi tethering too.
[GT540 Optimus General] somoant:
if more people confirm this, we can say that there is no problem with battery life,

only with %...
[GT540 Optimus General] MomirPeh:
I'd say that the problem exists definitely. Since I reverted to Quarx 2.2 rom I have almost double the battery life with the same usage patterns.
[GT540 Optimus General] SrkeeOSK:
first full charge, 40hrs, now charging second, it was medium usage, 2x25min 30rock episode watched & some tethering round 25min, other than that sms a few calls and some angry birds.

my worst problem is innacurate percentage veeery inacurate, just jumped from 30 to 5% in 5 mins. damn. :D

one more thing, out of the box tether seems not to work, had to install barnacle from market.

ONLY thing that pisses me off is touchscreen misalingment, if i ever go back to 2.1 it will be only beacouse of that. really annoying...
[GT540 Optimus General] Eth4n:
Anyone experiencing freezes while doing photos?

It's not an overclocking issue...i did it with 825 and 600mhz too,the GT keep freezing after random number of photos...
[GT540 Optimus General] MomirPeh:
True, that problem with camera freezes exists too... I had to use lgCamera app from market. Much better than built-in one.
[GT540 Optimus General] somoant:
maybe our bateries are just not fully charged, before at 100% i unplug charger and then connect it again and battery start charging again, i did it 2-5 times and battery life was about 4 days.

Yesterday i try not repeat 100% charging, just get 100% unplug charger

and using it. now i am at 30 %, looks like only 2 day of use. Strange.

I try find out how android knows when it stops charging... maybe there is some bad battery state report and kernel stops charnging, after charger is unpluged there si some code to refresh battery state... but i am not c programmer, and there are too many dependencies...

Update: after some calls battery back on 45% from 30%, strange.
[GT540 Optimus General] darkfield:
hi

i helped by myself and setcpu

with 245 - 320 mhz i had this problem, too

now i set 600 - 600 mhz and this problem is gone.

crazy but it works for me.

sry for bad english :D
[GT540 Optimus General] cagliostro13:
it worked for me as well..
[GT540 Optimus General] Frandroido:
I am also trying at 600-600 and despite it's too soon to confirm anything it seems that there is an improvement so far and, nice bonus, the menu opens in a heartbeat!

I don't know much about electronics but would it be possible to be a little like a car and that the increase in frequency would consume more power than the high frequency sustained?
[GT540 Optimus General] uzzo:
installed 2.3.3 yesterday night, unplugged the phone from 7hrs and i have got still 90%battery :D

the most amazing thingh is that cpu clock is 320-880 mhz!!!
[GT540 Optimus General] sligric:
Appears to have worked for me too!
[GT540 Optimus General] AntonJrL:
I've actually never had problems with my battery draining, are your phones just sitting there and draining?
[GT540 Optimus General] somoant:
yes, something like this, over night could drain battery from 100% to almost zero.

but looks like android/kernel problem, 'cause other devices users reported also this behaviour.
[GT540 Optimus General] m4rtijn:
Well i reported that the problems were solved, they are not! The accu drains in +- 11 hours to 0%..

Before the accu drained in 5 hours so the calibration worked a little bit for me :p
[GT540 Optimus General] torq1337:
Install the latest 2.3.3 from mur4ik

install the latest recovery 3.0.1.3

Install SetCPU and clock it about 806max 245min

in the profiles add PROFILE for ScreenOFF and make 480max 320min (Priority 98) AND SAVE.

After that, rape your mobile to the deadly 0 percent of battery life, then put it on charge and just let it all the night long.

With these setts my phone is holding for 4 days min without any probs ;)
[GT540 Optimus General] SrkeeOSK:
my phone fixed itself. dunno how. battery normally 2.5 3 days. :D
[GT540 Optimus General] hacker_didko10:
I was disappointed from the battery life too .... until I found ... this program ! Battery booster . It has risen my battery life up to 3 days !!! And now it's still 40% ! Absolutely awesome ! Before i found my battery life was around a day .

Make sure that these options are activated :

battery booster ---> battery tweak ---> smart battery saver

battery booster ---> battery tweak ---> security level ---> low

Here you are :
[GT540 Optimus General] lavero.burgos:
thanks, will test and report results

Ok, i have test this app and same thing it doest work, also i have notice my phone a bit unstable since installed. Uninstalling...

not working for me, control panel always crash

I don't know why . It works fine on my friends' phones and mine too ...
[GT540 Optimus General] ultrajv:
I went back to 2.1 for a while and noticed the battery charge indicator was incorrect on it. I wonder if wipe battery stats in clockwork recovery is working ok? Im using 2.5.1.8 - If wipe battery stats isnt working properly, that might explain why battery indicator works for some and not others.
[GT540 Optimus General] MomirPeh:
Is there anyone kind enough to explain where the battery stats are saved or where the voltage-percentage is mapped at all.
[GT540 Optimus General] RDilus:
to be honest i never notice a battery drain on 2.3.3 i tested it for 7 days with wifi on it takes 2 days standby 7 days gps 7 hours gps+wifi+bluethoot 5 hours
[GT540 Optimus General] deamonjones:
No that's 2.3.2
[GT540 Optimus General] Chxrlyglez:
Hi

I think the problem with the draining battery is the kernel, but we need wait a new release and pray for this problem will be fixed....
[GT540 Optimus General] Vuco:
Can anyone using Mur4ik's 1.5 (or softmoded by miroslav_mm or MMXTREM like me) confirm that when you charge your battery and it stops on ~90%, and when try again to charge it even more, but do not turn off your screen, it charges for ~20minutes more (then it says 100%) ? Just don't let the screen go off (I edit screen timeout option in display to 10minutes).

Battery Issue in 1.6

Any one facing battery issue in 1.6. ine dropped from more then a day to 16 hours only.
[GT540 Optimus General] mimm.m:
in 1.6 the battery is (i think) as good as in 1.5 and there i can have 2 days without stuck to the plug and thats quite ok
[GT540 Optimus General] :
I in my phone turn off auto-rotation and synchronization and my phone has been charged 2 days ago

Sorry for my English
[GT540 Optimus General] Eth4n:
I can confirm this,but with 1.4b.

Then it drops down very quick to 75%.

I'm really getting mad with this battery problem,and for every release i read about annoing (for me) bugs...seems that with 1.8 there's a problem with wi-fi and keyboard too. Let's see what happens :)
[GT540 Optimus General] Eth4n:
Can you explain how you use your phone please?

I turned off auto-rotation too,with only sync and mobile data active i get not more than 1 day.
[GT540 Optimus General] Vuco:
If you don't let the screen go off, you can charge your battery to 100%. And get some more battery life. Had mine phone the whole night on, and it went to 95% in the morning.

Try scaling freq from 122Mhz to 600Mhz from CM settings.
[GT540 Optimus General] Fabio R.:
Hi at all.... I try all versions, 1.6-2.1-2.2-2.3....the our destiny is recharge everyday :-( . Also because we USE the phone. Patient!!
[GT540 Optimus General] Eth4n:
Already did it,also with 122/~500mhz.

No way. I think that the thing that drains battery the most is not the cpu.
[GT540 Optimus General] somoant:
i agree, last version with no battery life problem is 1.3 or 1.4, and it is not kernel problem,

'cause the same kernel in 1.3 version (kernel problem is battery %)
[GT540 Optimus General] hacker_didko10:
I won't agree with you! There is no battery problem in any version. When you flash a newer version the battery information is being mashed and the battery life dramatically falls. So here is what you do to solve that problem:

1. Charge your phone.

2. Discharge the battery until the phone turns off by itself.

3. Try to turn the phone on until the battery dies completely.

4. Take out the battery and put in on.

5. Again try to turn the phone until the battery dies .

6. Now charge the phone without touching it for 3 hours and the problem will be gone.

Before that i was unable to use the phone for half of the day. Now my battery life has increased to 3-4 days with 1 hour of wi-fi, 40% brightenes and 1 hour listening to music with headphones.

I also recommend you to use a Start-Up manager and your problem will be gone.
[GT540 Optimus General] somoant:
thx for it, i know this procedure, i posted something similar on page 3 on this topic, i applied it before, but on this 1.8 version without success, then there must be something wrong on my side, i wil try once again do something with it, but i must make myself sure there is no other problem connected to battery draining
[GT540 Optimus General] chaosraser:
@ somoant i have the same problem with my battery after 8 houers it was off.

I think it is a problem with a google service task after you take a call
[GT540 Optimus General] somoant:
finally i figure out, Lotus Notes Traveler, i had older version installed on my recovery backups, on this (1.8) unfortunately new one with this bug

It took me whole day, uninstalling, checking a lot of processes, services, to find out IBM Lotus Notes Traveler with checked option "always connected" is responsible for battery is draining so fast
[GT540 Optimus General] Eth4n:
I hope you know this is the fastest way to kill a Li-Ion Battery.

This is the only solution right now

This is only onetime activity. Once reset my battery now lasts 2 days of normal use and normal charging.
[GT540 Optimus General] lavero.burgos:
i agree... this guy is way too stressed :D:D:D
[GT540 Optimus General] torq1337:
One problem from here :D

So i got SuperFast Froyo and the problem is... When i put the phone to charge, its jumps from 90% to 100% and says ITS FULL... and when I disconnect my phone from charging... it jumps to 95% then 90%...

I tried the FIXes like DRAIN your battery to DEAD, then wipe, and thats it... I did it... and nothing... someONE got an IDEA maybe !?...

ITS stops to fill my phone after it jumps to 100%, but i know that its missing the 15% of loading...

please help, thx a lot !
