What does being able to charge the phone while it's turned off have to do with solving battery problems?

actually I think this shouldn't be discussed here
[GT540 Optimus Android Development] mimm.m:
Hey

I like this rom but only every second or third sms arrives me ... is anyone with the same problem?

I showed in the task manager because i wanted to know if the sms app runs but there runns nothing ... i didnt killed the apps
[GT540 Optimus Android Development] Vuco:
The thing is, the battery doesn't charge to full when the phone is on. I measured it on 2.1 Super Optimum, and on 2.3. From 0 to 100%, on 2.1 (phone off) you needed ~2.5h to charge it. On 2.3 the phone was charged in 1.5h-2h.

Hell, even on 2.1 Super Optimum, when the phone was on it was charged in 1,5-2h, then you turn it off and it charges again for an hour (than the phone says its full).
[GT540 Optimus Android Development] mircea89fzr:
my guess is that the battery charge level is not displayed correctly. It may show 100% in less time, but it continues to charge even after reaching 100%. The problem with the charge level started in android 2.2 for our phone. The charge level is not correctly calibrated and this can't be solve by erasing battery stats, this is kernel-based. why else it does it drop faster to 85, stay longer on 60 etc. and being the same for everyone?
[GT540 Optimus Android Development] Vuco:
How can you confirm that it charges after it has reached 100% ?

On 1.8 or 2.0 SwiftDroid, I could charge the battery (and it shows that it's charging) for ~30min if you didn't lock the screen (display timeout to 30mins in settings-display, brightness to min). When you locked the screen, and unlock it, it would show that the battery is full every time.
[GT540 Optimus Android Development] mircea89fzr:
Because when it reaches 100% after 1.5-2 hours it drops quickly to 95,90... If you let it charge longer (I don't know the exact amount of time required to fully charge hardware based. I usually let it a whole night) it stays quite a long time at 99 and then drops much slower. For me, it's clear that the only thing that's software based is how the battery readings are interpreted in %. Charging is done at hardware level, that's why people could charge the phone while it was off (android hasn't even booted).

The problem started in a quarx 2.2 kernel build and from that point I haven't flashed a single boot.img that had an accurate display of the battery charge level. I don't know how to explain it, but I think you all observed a simple thing like 50% is not actually 50%. Like when the gyroscope was not calibrated and needed a special library, so it is with the battery I believe. Android does not know by itself the battery's capacity so that it can calculate how much is left. This or something else must be given to it. It all started with the custom roms because the devs didn't have the necessary data regarding the battery readings. This is simple put, but if Mur4ik or anyone else with knowledge regarding this issue can contradict me, then please.
[GT540 Optimus Android Development] lavero.burgos:
Somehow ive discovered that if you dont wipe stats prperly you will keep having the same problem that battery reaches until 99% so make sure b4 and after you install a rom apart of make a full wipe data/cache factory reset you also wipe dalvik cache nd battery stats. Somewhere i read is better to flash a new rom with battery full charged , and also is why some battery calibration apps recommend calibrate battery after you flash a rom (with full battery) .

Apart of that you can try changing timeout settings to 30 minutes after you reach 99% so it keep charginga and after 20 minutes or s with screen on is possible you reach 100%.

It has happened to many users included myself, but most likely after make a full wipe and flash a new ROM is a very clean way it fixes.
[GT540 Optimus Android Development] Mur4ik:
Exactly. This feature is not in my nearest plans.
[GT540 Optimus Android Development] eoghan2t7:
no problem mate. can you tell me what file or files control the battery persentage please so i can tweak it a little lol
[GT540 Optimus Android Development] mircea89fzr:
I know nothing for sure, I was just guessing how things work in android.
[GT540 Optimus Android Development] hansman:
Best ROM. Battery life is much longer.
[GT540 Optimus Android Development] bataya:
Gr8 rom Mur4ik, tnx... you have a beer if you ever come in Serbia. :)
[GT540 Optimus Android Development] mimm.m:
is this normal or is that a false of the GSM ?

i leave the sms app running ... but the same problem :(

any fix ideas? please?
[GT540 Optimus Android Development] domy1985:
What apps are you using for notification? I have no led but have a problem with missed calls...while receiving a call i can not see who is calling i see the phone icon jumping on the screen until i.press back button
[GT540 Optimus Android Development] mimm.m:
No i use the standard sms app but then i would also have a notification .... hm but thx for the idea
[GT540 Optimus Android Development] martin255:
Mur4ik could you fix the bluetooth sometime?

I can't send/receive files via it.

Other GT540's: TOTAL FAIL.

For example: Nokia x6, another older nokia: WORKING

Samsung Diva: sometimes fully, sometimes only send or receive.
[GT540 Optimus Android Development] max1919:
Is adb working in 2.2 and 2.3??
[GT540 Optimus Android Development] mind_challenge:
works for me
[GT540 Optimus Android Development] fishears:
Yes for Swiftdroid & Littlebrother
[GT540 Optimus Android Development] djdeeles:
Also Bluetooth file transfer works send and recieve
[GT540 Optimus Android Development] i050853:
Why TOTAL FAIL? Bluetooth works perfectly. Install Bluetooth File Transfer for free from Market and try again ;)
[GT540 Optimus Android Development] martin255:
Will give it a try, thanks.
[GT540 Optimus Android Development] lukemovement1:
Not shore but are the volume button supposed to switch place like in 2.1?
[GT540 Optimus Android Development] MomirPeh:
In 2.1 the volume buttons switch place only in landscape orientation, not in portrait. Anyway, I don't see it as a feature worth of an effort... Correct me if I'm wrong...
[GT540 Optimus Android Development] mejack03:
M4 battery life is not good for me. I can able to use my phone for only one day :(

So flashed M2 Boot.img and now i have 2 days battery back up :)

wat about u guys?
[GT540 Optimus Android Development] maxgreece:
So, to check I understand this, you are running M4 with the M2 boot.img?

If that works I might try it too - my battery life is only a day at the moment with fairly minimal use.
[GT540 Optimus Android Development] mejack03:
Yes i am running with M4 System.img, and M2 Boot.img
[GT540 Optimus Android Development] despotovski01:
Can you upload your M2 boot.img please? I don't want to download the whole ROM.
[GT540 Optimus Android Development] mejack03:
Here is boot.img from M2
[GT540 Optimus Android Development] mimm.m:
i don't know what you do with our phone i have also the m4 (m4 boot + system) and i have with lots of sms and normal surfing 2 days with battery (i overlock it to 806 and 600 when screen of)

it is not a insult but i can't understand it sry (but i know how frustrating it is when the battery is down after 1 one day)
[GT540 Optimus Android Development] :
You should set your minimum speed to about 245mhz as your processor runs at 600mhz which is too high for screen off this will save more battery.

Jack
[GT540 Optimus Android Development] Dilbao:
Sadly, I agree about that. M4 is kind of bad about battery usage on standby. Without any usage of phone, it takes about 4 days, however it takes about 2-3 days with normal usage, like wifi and games. I wasn't suprised about 3 days but even without using phone, it should improve much more then just 1 day.

So, I'm not quite happy about its standby performance.

Also, I have a question, does wifi tethering in settings should suppose to work or not. I don't need it but find out it's not working at all. Although, Barnacle Wifi Tether working fine.
[GT540 Optimus Android Development] mimm.m:
yes i know, but i don't like it when the lockscreen is so slow .... but it don't runns with 600mhz ever it only works very short (when i get a sms or stuff like that) but so the battery is about 2 days so i'm happy!!

edit: hm .... for me the battery was never as good as in M4 ..... if i flash the boot.img from M2 all user data would stay on the phone, doesn't they? ... so i will test it tomorrow ;) and i will give it a chance
[GT540 Optimus Android Development] mejack03:
Your battery lasts for 2 days with M2.. hm good. I am "jealous"

Edit : Ooops it is supposed to be M4 instead of M2
[GT540 Optimus Android Development] mimm.m:
no ... you must misunderstood me .... i didn't have the m2 i have the M4 or have I misunderstood you?
[GT540 Optimus Android Development] bataya:
anybody try to remane akmd2? any gain in battery life?
[GT540 Optimus Android Development] m1st3r1:
yes i understand u... u set ur cpu to 806 when screen on, and 600 when screen of.. and yet u still got 2 days of battery,,, am i right?

well for me (set cpu @ 600-245, on demand via cyanogenmod settings) it'll only last 10 hours.. i dont know, what ur syncing services? i have plume (30 mins), d7 google reader (2 hrs), whatsapp, enhanced email (1 hour), trillian (lots of it) and spb shell with the weather (2 hrs), lots of sms (go sms), and few calls, not to mention contacts and calender. and little (bout 30 mins) of rockbox/poweramp listening when im in the street. n it's all in 3G bout 60 percents of it n 2G bout 40 percents.

still, i wont complain
[GT540 Optimus Android Development] i050853:
With M4, i calibrated the battery and then i got 2days and 10hours from 100% to 10%. Don't know how much would last the 10%, but it seemed to me a nice amount of time, since i used wifi, played angry birds, made calls, sms..
[GT540 Optimus Android Development] smg72523889:
I also did calibration, use setcpu with 122 to 880 / screen off 122 to 600 and i can confirm 2 days of usage :)

Just install BatteryCalibration from market and configure setcpu in the right way ;)
[GT540 Optimus Android Development] richarddwyer10:
I have had 1.5 for a long time as it works fine for me but I now need to sim unlock my phone I have a code but l can't get it it work with this fw.I need help with this please. Thanks
[GT540 Optimus Android Development] nocio:
for that you need to have android 2.1 not 2.2 or 2.3
[GT540 Optimus Android Development] eoghan2t7:
try putting a different sim card into your phone and it should ask for network lock code
[GT540 Optimus Android Development] fishears:
I second that. You can only unlock with a stock 2.1 ROM
[GT540 Optimus Android Development] lukemovement1:
Not at all shore but you could try setup the apn, if not just backup, flash 2.1, unlock then restore.
[GT540 Optimus Android Development] ammarcool12:
waaa u guys already got 2.3.4??? does the video calling app work? :P

has anyone made a video of it?

damn i soo miss my optimus :P
[GT540 Optimus Android Development] mateusz344:
I have fixed my problem with "SD card unexpectedly removed". All I had to do was fixing problems with fat32 and probably corrupted files from gps navigation.

Steps I've done:

1. copy all files to computer

2. remove partition using any soft lipe partition magic etc.

3. create new partiotion, scan for errors, copy files from PC to SD.

After this, I haven't seen this error anymore.

BTW: What happened with Android Market i M4? I have no icon on program list despite fact, that AM is installed.
[GT540 Optimus Android Development] miksontije:
i tried this but still have errors. is there a clean version of M3 or M4 with lg imei and fixed russian profile and meny icons language? for me best working version is M3.
[GT540 Optimus Android Development] Vuco:
Setup your google account and Market will show in app list.
[GT540 Optimus Android Development] lavero.burgos:

[GT540 Optimus Android Development] MomirPeh:
Is anyone else using Swap with this ROM?

I'm using Swapper 2 with swap partition and now everything now seems much more responsive (and it was fast even before), no more lags of any kind, Angry Birds loads a LOT faster, etc. And the phone is running at stock clock of 600MHz.

If any of You is using swap, please share your settings and experiences.

I use:

- Swappiness 30

- Swap partition 128M

- swap partition: /dev/block/mmcblk0p3

- partitioned through Clockwork recovery (ext is 512M)

- busybox is already installed, so busybox location setting is empty
[GT540 Optimus Android Development] despotovski01:
I use Swapper too. I have set swappines to 10 and swapfile size to 64m. Since I'm using Swapper, no app or game makes my launcher app to force-close. :)
[GT540 Optimus Android Development] mimm.m:
hi

i have the m4 and

because of the good experiences with the m2 boot.img (battery life) i have flashed it but know the phone stucks at the swiftdroid logo (now for 20 minutes) what shall i do? maybe the m4 boot.img again?

thx
[GT540 Optimus Android Development] EazyLuke:
Yes, that should fix it I think.

[GT540 Optimus Android Development] tejasjadhav:
Try disabling GPS or Geo-tagging. The camera waits for the GPS to acquire the location and doesn't save the picture unless it gets the location. I had this problem before.
[GT540 Optimus Android Development] j41:
Just how much battery does something like Spb Shell 3d take?

In the long run ofcourse.
[GT540 Optimus Android Development] lavero.burgos:
It takes like 40 MB of RAM and i get a day , sometimes a day and a half with it plus other heavier apps working all the time
[GT540 Optimus Android Development] Dilbao:
Up to Android 2.1, you can read and store to SIM directly from contacts application. However thats not possible in future roms.

There are some apps to copy sim contacts to phone but I'm looking for more direct solution. I was wondering if that's possible in any way.
[GT540 Optimus Android Development] martin255:
With even the integrated phonebook you can import your contacts from your SIM.
[GT540 Optimus Android Development] Dilbao:
I know that but it's not what I was looking for. Because you can't export them back to SIM.
[GT540 Optimus Android Development] mejack03:
@Dilbao

U shud search for the application

I have a problem with the phone signal (phone and wifi issues with some networks) most of the time the phone is unavailable, i didn't have this problem with the original 2.1(baltik edition if i remember correctly) version, does anyone else experience the same issue?

Is there any way to flash back the 2.1 radio only on m4 version?

Thanks for the great work on this rom the phone is flying never felt so smooth again.
[GT540 Optimus Android Development] EazyLuke:
Do you have a bad signal? Or is the reception good, but you still cant be called?
[GT540 Optimus Android Development] adz63:
Sorry if this has been answered b4 .i really aint got time to look through almost 3000 posts. I put this on my gfs phone last night and was wondering how fast it can be over clocked too stabily.
[GT540 Optimus Android Development] eoghan2t7:
i think 806 is the most stable it can go.
[GT540 Optimus Android Development] djscooby:
In areas where with the stock 2.1 i had signal ,now i don't and in some wifi i previously can connect now i can't..

Btw i followed the upgrade instructions exactly line by line but i am suspicious about the Europe firmware (the one that on the guide suggested) i flashed with fastboot support cause the baltik one doesn't have fastboot does this had to do anything with my problem
[GT540 Optimus Android Development] eoghan2t7:
the only thing i have noticed with the signal is that i now have to be closer to my wireless router to get a connection e.g. in the same room as the router if i go into the next room the connection is lost also with the GSM signal works fine for me when making calls and texts but if i goto use O2-UK internet the signal drops and i have to refresh the page about 10 times to get the page to load.
[GT540 Optimus Android Development] AntonJrL:
Hey guys. Idk if I have m4 or not. How do I check?

[GT540 Optimus Android Development] Eth4n:
@806 and 825 mhz i have no problem at all. Going up to 844, after some time the phone freezes.

Edit: I have the Camera freeze problem too. Trying to disable the geotagging doesn't solve the problem.
