Greenify + betterbatterystats

Two great apps that will help with battery life
[LG Optimus 3D] mchartier:
Am i the only one getting significantly BETTER battery life on ICS? :confused:
[LG Optimus 3D] p-vlad:
No. You are not. ICS consume much less battery due to the better RAM organization and memory killer. Just in many ROMs there is too much stupid programs and in many KERNELs are not optimized. Moreover people compare all data switched off of GB and the many process running by default in ICS that they can switch off.

The ROM/Kernel combination (by Acura) in my signature give me 48h battery life - the same like the GBs by Acura or Darkroom Team.

So... it is better not to compare STOCK GB with STOCK ICS - you never know the tweaks and running stuff by default. Better compare Developer GB with the SAME developer ICS ROM if you want to claim such a think.
[LG Optimus 3D] Kasalla:
AW: Android Experts Only - Battery Drain

No, mine is better, too. :)
[LG Optimus 3D] botson71:
Me too, at least comparing the stock GB with the stock ICS.

There's no use of comparing custom ROMs/kernels anyway.
[LG Optimus 3D] p-vlad:
nope. other way around. you never know what kind of sh*t is on is in STOCK, and you know that custom (developers) ROM are clean form most of them and tweaked for performance and battery. Stock mean ... "tweaked" and filled with bloatware by LG - nothing more.
[LG Optimus 3D] botson71:
True about the custom roms but you missed my point about the stock roms.

When someone claims for example that "the new xxx rom for my phone is worse/better than the old yyy rom", you have to ask "under what conditions". And in order to make a reasonable and reliable comparison, you need to compare the old and new stock roms and run the battery benchmarks only on those.

This is exactly what the biggest tech sites and magazines do when comparing the batteries. They run the tests on STOCK conditions/roms with as few apps as possible, apart of the stock apps.

Battery comparison is a delicate business. For example, even if you have the same two phones with the same stock roms, if the one phone receives a weaker 2G/3G or WiFi signal, its battery will finish much faster than the other one.

And if you start adding apps, changing to custom roms, kernels, radios and bootloaders then you have far too many factors in order to make a reliable comparison.
[LG Optimus 3D] Android1993:
Okay, I tried geenify and bbs on a full charge and experienced no changes. My battery is dying quickly as we speak. My battery went from 81% to 34% in 5 1/2 hours in idle. I don't see how I'm having this issue and everyone else isn't.
[LG Optimus 3D] p-vlad:
"biggest tech sites and magazines" do PAID "comparisons" from A to Z. Do not trust any of them. Better compare best of X with best of Y. Or worse of X with the worse of Y. Like a scientist and like computer overclocker I know what means "Average" values.... there is no such a think. As i said - stock is just made by somebody... that is all... and here the developers are better. Moreover you do not know the current person how install the "Stock" Rom. If he did reset, if he still is on ext3 or on ext4. Does the person did a hard reset or not. Does still keep old baseband by installing the simple BIN or the BIN with baseband or the KDZ (bin+bb). different basebands different signal power etc etc etc... thats why i said BG of X with the ICS of X developer - they use nearly the same tweaks in all Roms with additions.
[LG Optimus 3D] jocazmaj:
I had battery drain problem on all roms since GB untill v28b.

I lose about 1-2% during the night with wifi always on..I mean really always ON.[Thats 2% during 8h of sleep, on darkroom v2 i had 35% loss]

During the day my battery can last around 12h-15h..

My other,extended battery 3500mAh makes things a lot easier for gaming. I recharge them during the night and woooo..

V28b is the best rom and you should try flashing kdz with Mobile support tool like this:

http://p92x.acidhazardrom.com/guides/lg_flash_tool.html

There have been problems while flashing bin and fls but you never know, it's different for any user.

The second thing you should do is to erase or freeze any system app that you don't use.

For example I erased adrenalin6,gtalk,lg apps,........... and left only the apps that I really need.

I'm on stock v28b with the stock kernel and I have no problems.

And buy a new battery, maybe that's the problem..They are cheeeeep.
[LG Optimus 3D] toty250:
me to i have a very good lif batterie after flashe 28b i sharge it 100% wifi 3or 4 h day blut 1h day ande calls lyck always

for 1 day in GB v21e at 19:00 may batteri is in 20 or 15% CHARGE

in v28b for 1 day at 19:00 may batteri is in 55 or 50% CHARGE

send from my LG p920 ics v28b
[LG Optimus 3D] xbsall:
That is too much loss IF what you say is correct that your phone is idle..

My O3D with wifi on and ICS during nighttime goes from 100% to 95% and btw my battery is the original that i bought with the phone back in the summer of 2011.

It doesnt run on stock ROM but it does run on stock kernel for now...

And btw guys forget about magazine tests and such BS because they are just promoters...

Never compare STOCK ROMS with CUSTOM ROMS because custom ROMS will always be better than STOCK, thats the way its meant to be.
[LG Optimus 3D] Android1993:
I reverted back to GB, factory reset, now I'm flashing V30B one last time, I'll do a factory reset upon starting it up. Let's see if whatever has been broken the last 3 times gets fixed.

UPDATE: I think I got down to the issue. The phone isn't correctly reading the battery. I did a shut down and reboot and it went from 93% to 86% , I then plugged it in, shut it down and reboot again and it read 100%.

I'm done. I'll probably stick with GB til I get a new device.
[LG Optimus 3D] botson71:
You missed my point again. :)

Of course the good tweaked custom roms/kernels etc are far better than any stock roms, and not only in battery life, there's absolutely no question about that.

But when someone claims "the ICS rom has better/worse battery than the GB rom" it's much easier and more reliable to compare the ICS/GB stock roms than the custom roms, because of the much fewer degrees of freedom.

In a nutshell:

-Comparing, e.g., GB 21E stock rom with the ICS 28B stock rom: easy.

-Comparing, e.g., GB 21E custom rom which has different tweaks/kernels etc with an ICS custom rom which has again different tweaks/kernels etc: not so easy.
[LG Optimus 3D] capnmorgan80:
I'm having the same battery drain problem with mine too. Its driving me crazy to have to charge my phone 2-3 times a day
[LG Optimus 3D] p-vlad:
i got your point but....

lets hypothetically say:

1. Stock ROM GB give 75% of the max possible (best score of LG developers for 2 years developing from v. 10A to 21E). Stock ROM ICS 50% of the max possible (best score of LG developers for first leaked ROM)

2. Custom ROM GB - 99-99-99% of the max possible (best for developers A1, A2, A3). Custom ROM ICS 96-98-99% of the max possible (best for developers A1, A2, A3)

so...witch you think is better to compare - 50 with 75 from the max possible ("max possible" is the key phrase for speed, battery etc.) for LG

or comparing 98 with 99 for each GB or ICS custom... i would compare the last one. if 98 for GB is 16h and 99 for ICS is 14h ... then OK. GB is better. but not by original LG roms.

that is my point.
[LG Optimus 3D] itsmemario:
And another O3D tale...without happy end ;(

1.) Stock GB under heavy use (more then 3 hours of SMS, games & WiFi over the day) = A battery life of 13-19 hours

2.) Stock ICS v30a under minimal use (some SMS, little gaming and WiFi) = A battery life of approx. 10 hours

3.) Stock ICS v30a + ROOT, nearly no use at all over the day, no WiFi, (just 3 SMS) = A battery life of 7 hours.

After 2 hours in my jeans pocket = 68% of battery left

After 7 hours in ma jeans pocket = 8% of battery left (just 3 SMS written)

Then I read "Battery Re-Calibration" is of no use...and did not try it.

Then I read TaskKillers are nearly useless and un-installed "Advanced Task Killer"...didnt help. Re-Installing it didnt help either.

What is goin on here ?
[LG Optimus 3D] Dr. Mario:
May I suggest to check the CPU VRM (voltage regulator module) setting? I found out why, undervolting the CPU solved my problem. Voltage = ampere due to either linear and/or switchmode voltage regulator design.

EDIT: To clarify why voltage = ampere equations is true; ever wonder why PC motherboard gets away with shoving 100 Amps of power into the CPU without melting the 12V plug? In nutshell, battery trades amperage consumption for voltage shunted by inductor in switchmode VRM - in other word, battery have to work harder on higher CPU voltage settings but takes it easier at idle voltage.
[LG Optimus 3D] :
Here's screenshot of my OMAP4 Cortex A9 CPU VRM settings (That's to be tested as of now). Previously the VRM settings for 1 and 1.3 GHz were too high - 1.38 V so I had to drop it as it ran too hot whilst running my favorite game, Minecraft Pocket Edition. Now not so hot and the benefit is a quicker recharge time.
[LG Optimus 3D] oile:
Wich kernel are you using, dr. Mario? That 1300mhz voltage is crazly low! Is it stable? You may have a wonderful silicon! But i guess that generally 1,36v would work for everyone and yes, undervolt surely helps with battery
[LG Optimus 3D] :
I used iodak kernel. And I had to experiment with undervolt as per TI OMAP4430 datasheet's electrical specification - the reason I got away with this might be because of 45 nanometers node process used to make this CPU (I am not sure if it's made with Hi-k Metal Gate process but undervolting ability may point this out as a possibility).

P.S. 1.36 Volts is a tad too high for my liking (as I am also an Electrical Engineer), so I had to reduce the power to ensure it runs cool but I cannot guarantee this voltage ramp 100% hence I said it's to be tested. It may be stable today but goes BSOD tomorrow.

P. S. S. If SetCPU won't work, try Voltage Control. And make a backup of your ROM first then proceed with caution - I usually start easy first then if I am adventurous, I do Vcore limbo to the point the phone crashes.
[LG Optimus 3D] :
Since I recently have been forcing my phone to crash at 1.3 GHz, I now arrived at 1.25 Volts as the minimum at this frequency - probably due to northbridge's voltage bridge limitations. I dunno why though as 1.3 GHz is naturally locked by kernel unless explicitly asked for. The voltage at lower speed however is stable.
[LG Optimus 3D] :
LCD consumes the most current - a bit more than CPU VRM current consumption - I ran Power Tutor and played with LCD backlight brightness. Cellular modem also do consume some of juices. Try using Auto Brightness.
[LG Optimus 3D] Claudio67:
May I kindly ask you if u disable smartreflex via trickstermod? Cause for what I undetstood should be mandatory... correct?

Thx in advance
[LG Optimus 3D] :
You can try but then northbridge voltage will be forced to stay at full voltage, thus consuming lot more power than what's needed for FSB to RAM IO transferring and IO interface. That will eat more power. Smartreflex is basically a software-defined DVFS, in combination with custom Voltage bridge circuitry / clock distribution tree logics - similar to Cool'n'Quiet / SpeedStep in the x86 CPUs.

P. S. In the iodak kernel I am using, Smartreflex is disabled in 1.3 GHz throttle settings.

[Galaxy S 4 Q&A, Help & Troubleshooting] xda_biscuits:
Galaxy S4 vs others.

Hey I know there are a few other threads out there like this but they are not really specific enough. I'm torn, I'm going to be buying a new phone in the next month or so and I'm confused as to which phone I should get, I've looked at many comparisons and still can't decide which is the better buy:

Galaxy S4

LG Optimus G Pro

Sony Xperia Z

HTC One(Maybe a little small)

Any thoughts on the matter or feedback would be appreaciated. Thanks. :good:

Note: I do live in Australia so that may affect my choice.
[Galaxy S 4 Q&A, Help & Troubleshooting] 1337RYoN:
You're on XDA forums, and it's not a place for people who are new to android. You should be able to decide for yourself what features will be more useful to you. If you still can't, at least tell what features draw you on each of the phones.
[Galaxy S 4 Q&A, Help & Troubleshooting] gelo01:
Tbh, the best for you is to go on a retail store and compare those 4 phones then choose the best for you and the one that will satisfy your needs. It's just a matter of self preference. No need to start a new thread that may attract fanboyism, bashing and flaming wars. :cool:
[Galaxy S 4 Q&A, Help & Troubleshooting] 1337RYoN:
S4

Advantages: Best processor in the pack. Tiny form factor.

Disadvantages: Nothing really, unless you count the plastic body.

Xperia Z

Advantages: Solid build.

Disadvantages: Slowest processor in this bunch (still fast).

HTC One

Advantages: Amazing build quality

Disadvantages: Feels uncomfortable due to excessively angular design.

G Pro

Advantages: Good build quality.

Disadvantages: No stylus.

Personally, I would recommend the S4. It's likely that it will be updated to at least 2 major android versions like what happened with the S2. It has the most battery efficient AND powerful chip around.

EDIT: Is Australia getting the S600 or Exynos Octa version?
[Galaxy S 4 Q&A, Help & Troubleshooting] barondebxl:
I understand this is your opinion but

HTC One is super comfortable according to anyone that owns it, reviewers and users.

Xz is also waterproof which is a good thing and S4 pro is more than powerful.

S IV build quality could definitely be better but im ok with it.

And OP just go to a store like a user mentioned and go see what you like best.

I can confirm for sure that you can fry eggs on the back of the xperia z. After having heating problem with my nexus 4 I thought that was lg's fault but I was wrong, it's the snap dragon s4 pro CPU that has a problem with making devices really hot.

That's why Sony made it waterproof so that you can leave your phone in a cold water jar
[Galaxy S 4 Q&A, Help & Troubleshooting] persheshhater:

Hello,

I am new to posting on the forums but I have been combing through them since around the HTC touch days. I am having a bit of trouble with a Koodo HTC One V.

Info:

PRIMOU PVT SHIP S-ON RL

HBOOT-1.18.0000

RADIO-3831.19.00.120

eMMC-boot

Jul 2 2012,20:51:45

So here is what happened. I had rooted the phone and was using it for about a week, when an OTA showed up and I applied it. Things seemed fine for about another week or so, but then I lost service. Everything else still works fine just no cellular service. I believe that the radio config has become corrupt.

I managed to find a copy of "mdm.bin" and "amss.bin" for my provider and model, but I cannot seem to figure out how to load them on the phone. So far I have tried adding them to a .zip archive and using CWM, but it simply says failed.

Can someone help me with some easy to follow instructions? I have been playing with this for over 1 1/2 weeks now and I am making myself crazy. I have a backup phone right now but it is becoming very unreliable.

Thanks in advance,

Jordan
[HTC One V] lazyjordan:
I have also tried the most recent RUU, but the same issue persists. Could it maybe be that the Radio is not actually being overwritten? I am really at a loss here and hoping that someone can help me out.

Hello, I've had my moto RAZR i since Monday and I've noticed that some of my contacts have disappeared from my phone book. I'm sure I added them and I'm sure I didn't delete them.

I noticed this today because I couldn't find a friend in my Whatsapp list. I uninstalled and installed again, only to notice that about 3 other contacts had gone poof from my phone book. I then took the sim card out while my phone was off and when I inserted it back and turned my phone back on another contact disappeared.
