The LG Optimus One Thread

^^^ Wifi might be turned off, but Auto-Sync might be ON... The phone tries to check for update to email, contacts, picasa, google+ every minute... so that might have caused the drain...

autosync is on in my mobile also & it only sync mail & contacts when i turn on WiFi (no GPRS pack installed currently). from what i have seen, autosync won't affect battery life till you turn on data connection or WiFi & if you do, the battery amount used comes under that particular data label (either data connection or WiFi).

so autosync can be ruled out for eating battery life.

actually not.. as in lgO1 even if u bringtdown the brightness bar to 0, it wont off the screen.

yes. but from my experience no use setting brightness to 0. set it to 30-40%. usually display takes 10% battery in my mobile. brightness set at above mentioned value.

yea, i think i should. bt as he to busy, its better to ask users...

just post it in his thread & ask if this was cause of the kernel.

or flash the kernel again.

means ? all my apps needs net connect through wifi..

i think he meant some wifi power management app or something like that. so it may have turned on wifi.

ALSO, if there is no wifi signal avl & you turn on wifi, it won't show in the status bar but will continue to draw power.

so hw do i reduce it more..

can't, instead set it higher & check if battery drain is more.

auto sync off.. network notification off.. nw its showing 22% battery usage.. hw the hell dats possible.. when i click it.. its shows "wifi running"

no..
1. auto sync off
2. bckground data chk off
3. network notification off
4. use wifi for location off
5. is there any other i need to chk.......

still showing 22% usage of batt.

reflash kernel & hope this problem is solved.

[Hannibal09]

few q on 6.5.5...

1. battery usage shows like this...
standby=44%
idle=35%
wifi=5%
display=11%
system=3%

*even its showing wifi on, its nt.
*i reduced brightness to 0% frm settings. still its showing 11% usage !!
*is standby n idle usage normal ??

As far as i know, its not showing battery usages at that point of time. Its showing percentage by which the process drained the battery

 

[gmg9]

new findings.......

when i click on the bluebar line in the battery usage window..

gps on......
wifi on.....

in real gps, wifi totaly off..

and now i seeing ndrive n gmaps using 2-3% batt...
cant kill/fc ndrive.. gmaps can be stop.. bt reshowed again....

nw wat.........

 

[tmanikandan]

Though the settings of Wifi and GPS turned Off ( but actually it states that GPS and Wifi On in battery usage ), Can you browse now ?

Also try to refresh the battery settings.

Also try deleting the cache using Apps like Click Cleaner or History Eraser.

Try to manually kill the ndrive using Advanced Task Killer ( don't use Task Killer )

As u rooted your phone, U can also try to use Droid Wall.

Also on the safer side, scan your mobile using Look Out Security.

If Problem still persists, contact franco as stated or post in xda.

@gmg9,

Go for CM7 6.5.6 + Franco's 18.1 kernel patch + ZRAM. Don't downgrade to 6.5.4... its not really better...

why zram.. as per the kernel post its already included in the kernel..
i heard v18.1 has battery drain issue. better is v18 as per many user..

my main concerns on 6.5.5 r ....
1. gps not working perfectly
2. dont like the fm app and dial pad at all
3. for some reason even i am not using wifi-gps, in battery usgae section its showing wifi-gps on...dnt knw why..

4. some times bt wont just turn on..had to reboot for it to work..
5. even its stable.. still its a beta version..

from Franco's Kernel XDA Page

Did you follow this ?

Take note of this, I don't care nor will pay attention if you say you're having battery drain if: you flashed the kernel sooner than 24hours of your complain post, if you didn't wipe your cache partition before or after flashing it, or if you didn't wipe your battery stats. If any of these three conditions are met at the time of your posting I will simply ignore it.

------------------------------------------------


Did u follow this ?

1.Download the kernel..& place it on the root of the sd card
2.reboot into recovery
3.wipe cache partition
4.wipe dalvic cache & battery stats
5.install the zip from sd card
reboot..zram not needed bcoz already included in the kernel..

You can also ask for help there. So just read and try to flash properly. If problem persists, u can post this in XDA page or try some other kernel / rom combinations ...but CM7 with Franco Kernel 18.1 is best

 

[gmg9]

i didnt flash any seperate kernel. just using whatever comes with 6.5.5 ...

 

[tmanikandan]

Did you wipe the cache and battery stats apart from dalvic cache before flashing ?

 

[gmg9]

yes...

going to flash 6.5.6...
anyone here flashed it yet.. any bad experi....???

 

[AndroidFan]

I am on 6.5.6... Its good... No problems at all...

Don't forget to flash Franco kernel 18.1+ZRAM afterwards even if its included...

i think the kernel comes with 6.5.6 is v18.
zram is included in the kernel v18.1 as per franco. no need to flash it again. right ?
and 18.1 hav battery drain issue...

i am going wipe cache/delvik-cache.. do i need to wipe any other thing..
