[Q] Increase battery performance on Optimus x2

What is the best way to increase battery life on LG P999 Optimus X2?
Model: LG-P999 (Wind Mobile Canada)
OS: 2.2.2
Baseband: M6600A-SCAUTNZ-2.0.9.972T 1
[JUL 15 2011 10:00:00]
MP:TRULGLE_08.09.02R_MDM
Kernel: 2.6.32.9
Build: FRG83G
Software: LG-P999-AWC-V11h
Rooted: YES
Or would it better to put on a custom ROM instead that looks identical to the current stock?
I am not sure if this battery issue maybe due to the fact that I had O2X installed and then flashed it back to a backup copy I got from XDA-Dev but ones again not sure, it just seems battery now die's even faster then it used to with STOCK firmware without CM7 and O2X

Isnt that a g2x
http://forum.xda-developers.com/forumdisplay.php?f=1114
Otherwise I am happy with battery performance on Miui 1.11.25

I don't think so since its 2x is also P-999 unless it P-900. I heard Miui lacks some features and has problems dealing with stuff like MMS and others.
Would still love to reduce battery usage

Your phone is a g2x as its real name p999 proves it. Canadian providers falsely renamed it o2x.
O2x is p990. Nobody had the unique solution for battery. Too many factors.
As hardware, kernels and ROM are different, you should ask on g2x threads.

LG optimus X2 (P990) battery charging
Hey guys I bought my LG OX2 a month ago, and I do have a few phone/tablet chargers, one for my blackberry, one for the kindle fire and one for my LG-OX2. All of them have the same connection, so I thought i will keep my Lg charger at my office and use my kindle charger to charged my OX2 at home. I was using CM7 and i had no problems at all. A few days ago I flash it with NOVA HD+ and first couple days charging over night with the kindle charger had no problems but after that in the mornings my phone is completely shut off. So i have to take the battery off and back on to start it. This morning i notice it again but the battery was empty, so i connected again and after 20 min was doing fine but after 40 min the phone shut off again completely and was very very hot specially where the camere area is. Anyone knows if is because I'm not using the original charger or is the new rom NOVA HD+.
Any suggestions?
Thanks!

It shouldn't be the charger. All micro USB ports should have +5V on their power terminals (this is the USB voltage from your PC USB port).
EDIT: You can refer to this link
http://en.wikipedia.org/wiki/Usb#Power
EDIT number 2:
Unless, of course, your charger is defective.

Well yes you're right is not the charger. As i just connected to the lg charger and after 15 minutes i check the phone and was very hot and unable to turn it on. So I had taken the battery out to cool it off for a few minutes. What else could it be? I don't remember or changing or doing any tweaks.

I've seen a lot of complaining about exactly the same thing as you. I would try flashing temasek's latest kang and vadonka's latest kernel, which should be among the most stable ROM/kernel combination out there for O2X.
If you still get SOD (sleep of death) while charging the phone, it could be a defective battery, or a defective phone altogether. In which case I would suggest that you try to flash your phone back to factory settings and ask for a replacement.

I appreciate your input. At this moment is charging ok, no heating, no SOD (SOD hehehe funny). I have download it the latest NOVA HD+ and i think i gonna give it another try. If continues heating up while charging I will take your advice (although flashing temasek's latest kang and vadonka's latest kernel sounds more complex work for a newbie like me. Do you know if there's any tutorial to follow?)
I will post the result after the update.

It's very simple. How do you flash NOVA? Isn't it through CWM? Flashing temasek's kang and vadonka's kernel is exactly through the same method.
EDIT: Good luck
EDIT #2: Lol @ SOD

The first time I flash NOVA was thru rom manager. Last night i flash the latest NOVA (which seems to be a new version almost everyday) http://hei1125.hopto.org/Nova HD (CM9)/
And I did it thru recovery mode, this time I wiped cache and delvik. And seems like everything is working normal. I did charge it over night, no heating, no SOD, is working flawless. Camera, clock, email working fine, browser now works on landscape which before wasn't. Video still not working. (ooopsss as i'm testing the video the phone kinda crashed and i had to remove battery to reboot it).
But so far so good... I hope stays 'stable'.

Glad it's working better for you now
How do you test the video? I can record video and play it back without any problems. I can also play youtube videos. Never had problems.

I open muy camera app and click on record video and the apps shuts down with a message "sorry the camera was closed because of error".
I can play videos on YouTube without problem.
So for a couple times the phone has gone frozen and the only way to reboot its by removing the battery.

I use an App killer to kill all apps every 30 minutes. It really helps.

I have found the solution to the poor battery life on the wind mobile G2X.
The culprit is the stock battery. Get rid of it. I was getting less than 3-4 hours battery life from mine with everything I could possibly do to reduce the battery load.
I purchased an extended battery off e-bay. It is the identical physical size, but has 1950mAh.
I now get well over 24 hours battery life. Over 10 hours playing games/browsing internet.

A lot of discussions about aftermarket batteries in many forums (here i guess, too).
If there is a print on the battery like 2200mAh, actually it doenst mean anything. You can be lucky to get a higher capacity or maybe get one with less. Dont believe in the sellers claim

battery performance
in the market you will find same aplications like battery maintenance-very good for battery life

Toggle to 2g when not needed...
Lg2x had a huge drain issue with 3g up

[Q] How warm does your Galaxy Note get?

I'm kinda new to Android Smartphones (only Tablets till now) and i'm kinda concerned cause my Note seems to hit the 50°C Pretty fast (Wlan/Browsing).
My Rom: ROCKET ROCK v9
Got the temperatur via SetCPU
So now my question: what's the max safe temperature and: How hot does your n7000 become?

On the stock firmware, i occasionally find the top right part warm. Seems random.

Near the camera is a typical place for a powerful smartphone that's faster than my laptop is a good place to start. Haha. Its normal. but it should never get too hot to handle. Roms usually affect this. On my sgs2 I had this issue on stock. Then upgrading helped a lot.
Sent from my GT-I9100

Mine stays cool most of the time. Only ever gets warm when on charge and playing a game at the same time. I'm using Cassie's ROM and Abyss 2.3 kernel.

I was wondering this too particularly how quickly-hot does it get using the Wi-Fi hotspot?

Are you Happy With ICS?

So, ICS has been out for a while and people are getting it working on our phone quite well. Taking into consideration that most ICS ROMs aren't polished yet and most still have a few bugs to sort out, are you happy with it?
I'm not talking about what the devs here did to get it working on our phone (They are a bunch of little magicians, eh?), but what Google did creating it. I have tried a couple of ICS ROMs but I couldn't get it working properly on my SGS and went back to a stock Gingerbread ROM, so I am still not that aware of most of what ICS can do.
ICS is a big departure from Gingerbread and takes a bit of investigating to find where everything is, but that's part of the fun.
What would you change in ICS and what do you really like that wasn't there before, or has been improved?
I really like the Data Usage meter. It's a great tool for those who are always watching their monthly limits.
Ian

I enjoyed using ICS a lot, everything about it, from the look and feel of it to the smoothness and speed of the OS.
The only reason im back on GB is because of problems in the battery department, no matter what kernel I used, I had problems with the battery life.
Ill be definately making the switch once the roms mature more.

During last week I tried few ICS roms and finally I came back to GB JVU - SAUROM.
Last night i tested ICS CNA 1.4.0. It works quite well witch glitch kernel, but from my poiont of view it still not the same preformance what is in GB. I had some lags in app drawer. Settings menu was slow (with semaphore 0.8.1 very slow).
I overclocked to 1300 and it's improved performance but in AnTutu I reached 3008. In comparision to JVU Saurom it is over 400 less (in Saurom with Semaphore 2.5.0 my AnTutu results is 3480).
I like plays last "hi-end" games. I tried Modern Combat 2 under SAUROM and under CNA 1.4.0 (both overclocked to 1300Mhz) and under SAUROM JVU playing it's definitively better.
I'dont know what to do. I like ICS style, but I look for fast and stable system.
I'll join the question: how do you feel wit ics for SGS? and kind of ICS customs do you recommend for me?

Too bad we can't get the best Devs here to develop one version of ICS together. With all that firepower it should be no time before ICS ran perfect on the SGS.
I still don't understand why Samsung said they couldn't do ICS for the SGS when the Devs here can.
Ian

ics is smooth and a real eyecandy but actually i cant find a real lifechanging feature in it. was quite happy with 2.2, had unstable episode of stock kies 2.6 and endedup in aokp 2.1
ics works but im experiencing crazy bat drains from mediaserver and music playback on ics costs A LOT of battery
i guess i will flash 2.2 some day

Hello
I like the Slim version of ICS. I am currently using Slim 2.5 with the Semaphore_ICS_0.9.0 kernel.
With the CPU frequency set to 1100 (which is what I normally run) I get 3324* on the AnTuTu benchmark.
* 3335 + 3313= 3324 (average)
Note : One needs to be careful comparing AnTuTu scores using Semaphore_ICS_0.9.0 kernel. By this I mean that it is not necessarily a straight apples to apples comparison due to all the different kernel settings which are possible.
@+

I also use Slim with Semaphore kernel 0.9.0 and it has been an delight. ICS is so good that i would sell my phone if i had to go back to gb again Much of the bugs have been fixed by now, and really this custom roms are very stable. Onecosmio SGICS rc4.2 is also very good and polished. You could start with that one, also has great battery life in comparison with others.

I think its a bit laggy
but i might need another kernel? I don't know.
It looks good and there are a lot more options but i don't like the stock internet browser the one on gingerbread is great. Does exactly what i need it to and when you press the more button everything is in the right place.

Semaphore ICS 0.9.0 unable to get network
Flashed my T-mobile Samsung Galaxy S (I9000 using on wind mobile) to Semaphore ICS 0.9.0 and unable to get on wind network...have tried practically almost a lot of things including flashing other ICS roms, used the radios suggested in the forums but am unable to get it to work. Can someone suggest me the correct modem file to be flashed?

I'm loving ICS I'm using TeamICSSGS rom runs perfectly I find everything to work well and I've ended up getting between 2-3days on battery depending on how I use it.
I have no clue what Samsung was every on about saying the Galaxy S will never get ICS well whats running pretty good on my Galaxy S then

I think it works great. I love the way ICS looks and feel and also the fact that my SGS its a bit different from most sgs's out there.
battery is still problematic but since being a heavy user I carry a charger where ever I go anyway.
bottom line... Love it

Few posts ago I wrote that I came back to GB. I was not happy with ICS becouse of many resons, but now I have to change my mind - RC4.2 runs great. I have one small issue with Gmail app (does not work) but I think that something could be wrong during installation becouse other users don't report this error. I have to reflash RC4.2 and test it again.

I like ics very much. The design, speed...but i hate is battery drain. When i had 2.3.6 I could be on phone 12 hours straight till 0% (massive gaming over 3g or wifi) it was great. But with ics max i get is 4 hours non stop...thats sad...I tryed everything from millions of battery apps to kernels to voltage and dont remember how many guides on utube/xda/android forums about it...
When that will be fixed im back to it, till than Ill be on stable 2.3.6 gaming

You have an unusual phone .... or battery. Since I bought my SGS I have to charge it every night. My best achievement was 24 hours (becouse I fell asleep and forgot to connect charger)

Ics feedback
from my exp dark knight 2.1 (4.0.4) is best more stable giving maximum battery life...ics is userfriendly,more smooth and more stable...
the only problem is battery life but it will not effects me more bcz i only use internet for mails and sometimes music plus it gives me 24 hour battery back up(gps off,wifi usage moderate,data plan always on)

I only have a few gripes about ICS (THICSSGS 4.0.3)
- The dialer is not idiot proof enough for me, I keep making unwanted calls.
- For some reason my photos keep showing up in duplicate or triplicate. Kind of pain since I use the camera for work and when I delete the duplicates they appear again the next day.
- Sound volume is to quite overall.
- Can't make an appointment in calendar without an Gmail or similar account to sync to.
- Did I mention the SOUND IS TOO QUITE?
Other than these few things the move to ICS has been a good one. Last week I got nearly 4 days on a single charge but its averaging out to 2 days now. With GB 2 days was pushing it.

question to heavy-music-users:
1. do you experience high cpu usage on mediaserver?
2. any issues with screen off wifi connection used by interney radios or shoutcast? in my case winamp pauses every 20-30 seconds

Comparing ICS to Gingerbread, ICS wins in every single aspect for me, except for the ability of Samsung roms to play a wide range of media formats. ICS is faster, more ram-efficient, looks better and runs games more smoothly than Gingerbread.
However, I was previously on Froyo 2.2.1 ZSJPK before using ICS, because I preferred Froyo to Gingerbread. So, comparing ICS to Froyo, there are several things that ICS loses out to Froyo. To name a few, Froyo has way more free ram, hence better multitasking. On Froyo, I can have the browser running a desktop version of facebook as well as NOVA 2 running in the background, without either being closed. But on ICS, it's hard to even run Angry Birds and Contacts at the same time due to the fact that on average, there is only about 60Mb of free space.
Hence, ICS wins in all ways except multitasking, but that is due to the Galaxy S' limitations, not the actual ICS itself.

i had all time the Goa Rom on my SGS i9000 and now two weeks the ICS open kang Projekt and i was happy i find it is so much better we gingerbread the speed is very well
the apks open so fast it works very good for me
greetz nobody

Been using ics since Dec. Very happy with it and won't go back to gingerbread.

[Q] Battery Issues after update

I recently updated my Galaxy Note N7000 with the latest Indian firmware... DDLSC.. But after the update, I am facing a lot of battery issues. The battery does not even last for a day. It used to be much better with the older firmware(ICS). Please suggest me anything to get maximum battery out of my phone.
I am willing to install any latest firmware from any other country as well. It is not a problem or any other custom ROM that will solve my battery problem! I really need a lot of battery backup for my phone as I am mostly out of my house.
Please help me!!

Battery is always aproblem wif the note... i suggest take a look at ebay they are offering a double battery bank for 2300 inr.. that will really help u to get battery as they are giving out a batterry of 5300 mah. I personally dnt think a custom rom can help...
P.s. - if i ever meet a nokia official... i wud suggest them to stop making phones and concentrate on making battries and start exporing them to samsung or iphones lolz...
Sent from my GT-N7000 using Tapatalk 2

Hahaa.. Good point for Nokia
Anyways... Thanks for the tip on the battery!

I'm also facing same problem and many other just search ...after Jellybean update it seems like battery is dying rather quickly.I have already tried LT4 version and many roms ( TW based) but more or less same battery life..Only worked around is to disable Wifi and auto sync when not required because it seems it killing battery rather quickly..and i dont use auto brightness ..just change mannually screen is eating up around 50% ...by doing this I manage to hold on for 12 -14 hours...try sweet rom LT4 quite stable and good battery life ...

Very often after flashing a new a battery problem happen, it's necessary to calibrate the battery using appli like Battety Calibration.

That's a problem for a couple of users, unfortunately.
Specially JB rom ! I've tried several tips, like switch off wifi, sync, Google now, multi windows, battery calibration etc, without success.
Still waiting a decent rom in the future? (dreaming is permitted, right? )

[Q] [Battery related] S3 Mini i8190L update from stock rom to custom, is it worth it?

Hi guys,
i recently sold my crappy Xperia Tipo (i goddamn hate it) and bought an S3 Mini, i love it, it's my first day with it, but i'm having serious issues with the battery life, it discharges too fast,
When i bought it i drained all the battery, then charged it (turned off) to 100%.... but still its draining too fast.
The phone is brand new... i don't know why it discharges so fast, it's on android 4.1.2:
Should i update to a custom rom? i would like to taste KitKat, that CM11...
Do you suggest it?

The battery is not our great ally here xD
But custom rom have bugs, no matter what ppl say.. they have and will have for a while...
IF you dont care about warranty and want to take the chance to improve your cell, yes, there are some good roms to upgrade Jelly Bean to KitKat or just update to 4.3
Personal, Maclaw have a great work done in his CM and Carbon (Don Like at all Slim or OAKP ) that work with kit kat, still in process; in the case of 4.3 dont know, i just did the jump from 4.1 to 4.4

I'm actually using Mac CM 11.0 and I have to charge it every night, the same as with a Stock ROM / based custom ROM. I'm actually doing around 5 to 6 hours calling and a little bit of Line/Whatsapp during the day.
It's faster, and I like Open Source ROMs the most, because of the design, but it's up to you.

hey guys,
the road so far:
I started rooting and installing TWRP recovery in my phone, then i updated to Maclaw Kitkat 4.4.2 and flashed gapps...
i noted that the phone improved just a little bit, because without the bloatware it's much better, i don't have any bugs actually...
From 5 am to 11.30 am it went down 3% without 3G, i went to sleep and lost 3 % that's a little bit better...
I suggest to do a full rom backup with TWRP and try a new custom rom, 4.4 or 4.3!!
leave this post open for if someone knows something else about the battery life.

Dont know much how long is battery life with the stock rom, bcause i started using the phone directly with the CM11 of maclaw. I am running the 20140120 version, and i am always reading about the news and comments of the last maclaw's release.. (think i will do an update soon..)
I see that battery life increase changing the governor ( abyssplug ) and the I/O scheduler ( sio ). I dont use wifi so much but often 3g data connection (chat, mail pushing, some internet surfing etc..) , listen music, make some photos... airplane mode during night!
after 1,5 day of use.. i should charge!
had an xperiaE before with a stock 4.1.2 jb and the battery life was greater... ( but is completely another device with another hw and os .. )

I'm kindda pissed of with the Xperia line, my friend had the Xperia U and smashed it across the hallway because after hours and hours of flashing new roms it always came down to poor...extreme poor performance haha.
What's the governor ?

governor takes control of which the CPU is used... there are a lot of threads about...or just google the word and you will find a lot of literature..
