One power guard is good on ICS roms. Battery calibration however has long been proved a myth, why is it still floating around? A good few charge cycles does the same without wiping stats, it's a placebo, battery stats just displays what has used your battery in settings

Well my battery is awsome now. Well running LG Gearbox with settings 2 cores, 1100mhz. At the time my battery usage level: 1day 5 hours and my battery is still on 88%. Well also i didnt use my phone so much but for now its really better.

Hi every one,

I don'nt know exactly where I did read about this Deep Sleep issue here on XDA Forum but I can remember that some one posted how to get your phone in Deep sleep Mode. I did the following some steps to achive it ( but still original thanks to the person who wrote it )

1. If you got Root run your phone for 1-2 Hours after Rooting and then do the Factory Reset. ( I personally did Hard Reset)

2. Install Better Battery Stats to check what is the major cause of battery drain.

3. Disable Fast Dormancy to get less com.android.phone wake-ups http://xdaforums.com/showthread.php?t=2057093 ( Thanks again to Arne_B for this)

4. Battery Callibration. You can find this software on Google Play Store.

5. When you are done with 100% Battery Charging let your phone on charge for half and hour or so after achiving 100% Battery Level.

6. Remove your charger by unlocking your phone not in off screen mode.
[LG Optimus 4X HD] @non4:
Battery calibration is a myth, google engineers debunked that ages ago. Jellybean sleeps well even with 3g on, but if you want to stay with ICS use this:

well, i'm having some problems with audioout_2 wakelock waking my device too often. i'm trying to figure out what culprit could be causing it, but on the web there are tons of solutions, and they are obviously directed at different causes of the problem. if anyone has any idea how to pinpoint what app exactly is causing the wakelock, it would save me quite a lot of time i'll waste trying to find the solution by trying them all.
[LG Optimus 4X HD] hutjeflut:
indeed al that calibration apps do is remove a file with the stats in them.

this exact same file is also removed when your phone is charged fully and you remove the plug (this is why the statistics reset).
[LG Optimus 4X HD] Bogeyof:
Do u have sounds for tipping at the display or for dialing enabled. On ICS, there is a big problem and there are many wakelocks caused by this settings...

Today something wierd happend.

I have gone to sleep and the battery didnt lose 1% until someone phoned me. From there on it losed 3-4% an hour. o.O

Can you check your wakelocks and see if baseband_xmm_power was on? For me sometimes the baseband_xmm_power wakelock doesn't shut off for some reason, causing battery drain.
[LG Optimus 4X HD] tobixdev:
AW: Battery life

I already did this fast demorcy thing.

yeah baseband wakelocks are many see here.

Is there a fix for this issue ?

and whats that deleted wakelock?
[LG Optimus 4X HD] brunek:
Question..I amhaving big battery drain in the las couple of days after i flashed JB. I did the factory reset. My phone was losing through the night almost 30% with everything disabled. Today I made a root. It seams the phone can`t go into deep sleep,it works almost all night on 51MHZ(55%) and deep sleep only 15%. I cleaned cache, unlinked dropbox, disabled google maps.. Is there any other thing I could do? Any app that can help?(greeenify,titanium backup..) After root,even if the screen is of it doesnt show on my CPU spy,deep sleep stays unused..
[LG Optimus 4X HD] xtribas:
have have this baseband wakelock too, had it in leaked version, and in this official too. It drains a lot of battery! I searched everywhere, and i cant seem to fin any solution
[LG Optimus 4X HD] babymatteo:
Heavy usage. Pandora straight 6 hrs and texting, some calls, web browsing, Facebook and instagram posts. Pretty good IMO. I'm on Zaiben ROM. I disabled background data for a lot of apps and got good results.
[LG Optimus 4X HD] gmajnkek:
Here is mine from yesterday.

Didnt use my lg so much, but enough for my needs.
[LG Optimus 4X HD] Stevic Milos:
After i flashed to v20a first couple days i had 1-2% drain per night, but after a played in hidden menu trying to change FOTA server to EU-server my phone starrted to drain 12-15% per night. In the morning i always find DMClient, PC suite and Google Play active in Running Applications.

Can i disable DMClient or FOTA?

Auto-update is disabled.
[LG Optimus 4X HD] ErnieTSI:
Hi Guys,

I watched a kind of strange thing, seen under ICS as well as JB: in advanced WiFi settings I always activated the setting that WiFi shall be active in standby "only when the device is plugged in" or even set it to "Never". With such settings I never turned off my WiFi manually e.g. before going to bed in the evening as my thinking was that WiFi will be turned off automatically in standby.

After installing Better Battery Stats however I found out that my WiFi is obviously running in standby despite the above mentioned settings, sucking more than 10% battery during the night, pls. look at the screenshot.

Please tell me:

1. if your devices behave like the same or do I maybe misinterpret the result of Better Battery Stats?!

2. is active WiFi possible although the device is in Deep Sleep mode?

I do not understand why my WiFi is running 5h22min if the Awake State is 1h7min only and with the above settings, really confusing.

Regards

Stephan
[LG Optimus 4X HD] Captain Sisko:
Whats the maximum length of time a 4X has been on before requiring a recharge.

Mine has been on for 1 day 1h and 37 minutes so far.

Just left in standby and making a few calls, screen birightness as low as poss with Wi-Fi on.

When my experiment is over I'll screenshot my use and post it up.

Thought I'd see how far I can squeeze it as my brother keeps boasting about his Xperia S
[LG Optimus 4X HD] gmajnkek:
I got mine for almost 3 days. I already posted the screen in this topic (1 week ago)
[LG Optimus 4X HD] hutjeflut:
my record has bin 5 days with wifi always on even in sleep.

and with 2.5 hours screen on time during that 5 days.

i think 10 days is possible with less use but i cant get myself to test that i stil feel like playing with it haha.
[LG Optimus 4X HD] Captain Sisko:
I got almost 2 days - V20A calls, texts, whats app, some you tube.

Batt died just after the screenshots

Just popped on charge now

I usually have to charge at the end of the day, but I'm pleased with it's performance.

I might have to tweak some settings and redo the test - I'm sure I can squeeze a little more out of it
[LG Optimus 4X HD] skryptus:
Not to be a nag, but if you want to keep your battery healthy, you should really avoid letting it go to 0. With lithium batteries, fully discharging the battery is a no-no for battery life...
[LG Optimus 4X HD] Stevic Milos:
I'm getting 2 days ( +/- a few hours ) with:

3-3,5 hours of screen time,

5-6 hours of wifi (turn it of when not using),

No data (have no 3G),

20 sms ( +/- a few )

60-80 minutes of talk time,

in the end i have 15-20% battery left, never left it drop below 15%.

Yesterday while playing "100 doors 2013" i noticed phone gets hot but the game is not demanding and its far from a battery drainer (drains as much as screen itself) so correct me if i'm wrong but i think this game actualy work on tegra's fifth core.
[LG Optimus 4X HD] Captain Sisko:
Really? I thought it was best practice to fully discharge before recharging?

I let my phone shutdown, then plug the charger in when switching on so then it goes from 1/2%-100%
[LG Optimus 4X HD] skryptus:
Nope. For lithium batteries, everything you knew from the time of Ni-MH goes out the window. You should neither let it completely discharge (some people say do a full 0-100% cycle every 6 months, but I'm not quite clear how that's good, seeing everyone says full discharges are bad) nor worry about disconnecting it before reaching 100% (it has no memory, as we all know - some people even say it's better to do partial charges than topping it up, although I haven't seen enough of this POV to pass it along as advice).
[LG Optimus 4X HD] Captain Sisko:
Thats what I find puzzling

As when my brother and I had a Galaxy S2. My brother also had an additional battery charger.

So obviously the standard practice was to let the battery go flat, stick it in the charger and obv taking the full battery from the charger and sticking it in the phone. So then you can use your phone normally whilst one is charging away at home.
[LG Optimus 4X HD] hutjeflut:
with a new battery its actualy wise to fully charge and leave it on another 45 minutes then fully discharge it till it goes off (which happens at 2% so it never goes fully empty anyway) and repeat that a few times.

batterys cannt go fully empty these days as android shut the phone down before its empty.
[LG Optimus 4X HD] Manholas:
"LG Optimus P880 4X Flashed to V20A 4.1.2 JB Finally!! " One question, when you mention JB 4.1.2

FINALLY

there any more than the official update provided by LG's site 04Abr13 (Europe open)?
[LG Optimus 4X HD] skryptus:
I'm guessing this depends on the mobile. In some phones and tablets I've tried, it allows the phone to remain on with 1% battery, and then it doesn't let the phone turn on until after a few minutes, so I'm guessing it lets it go pretty close to 0.

Regarding the full charge on first load, I was always curious to ask someone who really knows about it if this makes sense because, due to the testing processes our batteries must go through before coming to market, and given they usually get to our hands with some load in them, our first load is never the battery's first load. So I'd wonder if that applies at all...
[LG Optimus 4X HD] gmajnkek:
Some ppl say its best to let it drain till it turn's off and than recharge it... So it gets calibrated.
[LG Optimus 4X HD] :
batt

i Have a day and a half with normal use, runing 10.1 CM...
[LG Optimus 4X HD] skryptus:
Well, the few reputable sites and web articles from reputable sources say that with Lithium batteries, letting it discharge harms the battery life.

I've seen a few people, around here and in other similar forums, suggest to "recalibrate" the battery in the way you referred every 6 months, but so far I haven't seen that approach backed by any study or scientific website/blog, which is why I say I'm not sure why that would be advisable, given the former.
[LG Optimus 4X HD] Captain Sisko:
I said finally as I was waiting for the update from LG's servers near the end of March when I first read JB was available. Then I got impatient and flashed it manually in mid April.

Hello guys, im a newbie in android, and my 1st phone is a LG 4X HD, i love the phone, but the only problem is the battery... i've read all your post and I can't figure out how to improve my battery life... for example at night i loose about 26% doing nothing...

I have JB instaled, i had better perfomance in general, but the play is not as good

as many people said in here, i tried to instal a task killer, a booster, tryed to kill apps, to froze them... i realy dont know what to do... i dont have an rooted android... i'll read something about it, but im afraid of loosing my warranty...

if there is a portuguese person here, i would thanked the help!

ty guy's! :good:
[LG Optimus 4X HD] xtribas:
im portuguese, the main reason of the drain is a kernel wakelock called baseband_xmm_power. Install BetterBatteryStats and see for yourself.

[Sony Xperia S, Acro S, Ion] xyberknight:
Am I the only one with this problem? The in-call volume level is maxed out, but is barely audible. I'd go as far to say it's worse than when the X10 came out with 1.6 Donut on it. Why can't Sony ever get a good loud volume level from launch? I've got xLoud enabled, otherwise I can't hear it at all. Does any one know of any apps that may help make this issue manageable for my Ion? I'm on ICS LT28h, just biding my time until the eventual release of the Xperia T on AT&T, which has been listed to have a 30% louder volume in call max than the Xperia S, so here's to hoping.

[Sony Xperia S, Acro S, Ion] Spectre51:
I don't have a problem with in all volume but the speaker volume is rather dismal.
[Sony Xperia S, Acro S, Ion] xyberknight:
I can confirm that volume +(volume boost) paid-(free if you sign up for developer's forum) can fix speaker volume, but not in call volume issue.
[Sony Xperia S, Acro S, Ion] 424aca:
Same for me

I think that this is a software related problem

reason:

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

when i use groove Ip (VOIP) i once set my caller volume to max (BAD IDEA)

and my ear almost burst open. So it could be changed through the software.
[Sony Xperia S, Acro S, Ion] King Cole:
Well, I can assure you it's a software problem, as any speaker can be adjusted to the volume where it'll immediately blow when you set it that high. The software is what limits it so as not to be able to go that far.

Only thing that I could think that is diffrent is the developers and one has the aokp extra settings tab and cyanogenmod has its own settings and wallpapers.

Is one better than the other and which one do you prefer?
[T-Mobile, Samsung Galaxy SIII] joshnichols189:
That's about it. They're both built from source. AOKP has a couple more features. They're both really stable though and I prefer CM10.

[T-Mobile, Samsung Galaxy SIII] imheroldman:
They are fairly different...

AOKP has their own source though they do use quite a bit from Cyanogen. They offer the navbar to be enabled which Cyanogen doesn't.

CyanogenMod has a long standing history of being the first and the best... its just true. I would venture to say that their AOSP kernel is the best on the market the update almost daily with input directly from Qualcomm! The big feature that I am fond of is the profiles settings which you won't find most other places. These allow you to set custom "profiles" for different scenarios like work and home that will automatically do just about anything from turning on and off phone function s down to running individual apps. These are also able to be written to NFC tags... you can see the awesomeness?

Ok im a fanboi...
[T-Mobile, Samsung Galaxy SIII] The Doctor04:
I have always thought of AOKP includes the best of AOSP an CM. I like them both but prefer AOKP. You can drill down into your device a little deeper to tweak it further in kang. Both are great ROMs though.

I get this problem whenever I flash cm9 direct from the cm site. I was advised to go back to stock first and then flash cm. I flashed the 4.0.4 from boy racers ftf list, booted in Stock, powered off and flashed the baseband from the fxp thread, booted up. I then used cm9 from the fxp thread rather than cm9 site and got stable WiFi.

I like pratting about though, so I'm now on rooted stock 4.0.4 using the guide in this forum to create your own rom

Thanks guys, finally some answers.

Here is my situation,flashed JellySandwich 4.3 (so far perfect ICS for me), tried sirkays 7.431 (rom is developed and tested with that version) and flykernel 0.7 and flykernel 0.8.

Nothing, one or two connections, 200 tries.

Then, 6 hours before tried sirkays latest 9.587a, with him is better but stil half-half situation.

"If still the problem persists then flash kernel modules found on that thread !!" will try this,thanks.

Full wipe done, etc.

On repacked4ru rom for example everythings working perfect, never experienced single problem with wifi. (same ap,my home ap)

Once again, flashed with full wipe, cache wipe, dalwik cache wipe.

Tried multiple times,result is every time the same (also redownloaded rom) and tested same kernels with other roms, they dont cause problem by themself.

Router isnt problem.

But, that what realy frustrating me is this problem is very common on android but i didnt seen in hours of googling what realy causing him.

Tell me please guys, im a noob but not stupid and learning fast.

To cure some problem man must knows hims root, whats causing that problem.

Try picking up a pure stock ftf file from boy racers thread. I have a copy of the last gb stock ftf and two stock ics ftfs stored on my pc so if I screw up, I have options. I had this problem of reconnect loops using cm9 as above and pretty much reverting back to stock was all that cured it. Once you've flashed stock you can then go about the business of putting jelly sandwich of whatever rom you want on.
