battery consumption problem caused by bad voltage handling?

so I downloaded somekind of battery widget that have graphic log on the voltage and I noticed that when my new optimus 4x's voltage jumped between high and low it cause the battery to drop rapidly... CMIIW, I can't help but feeling that this is very much like those happened at contemporary desktop CPU that constantly adjusting voltages, however with the bad efficiency one, not sure if this is LG's fault or Nvidia's, anyone here have article reviewing/explaining the Tegra 3 platform? CMIIW, the CPU is Nvidia's right? or is it somebody else's CPU?
anyone else noticed similar behavior? any suggestion on improving the battery life?

When root will come out, definitely will improve battery

Just wanted to ask this question on this forum.
This battery drains terrible fast.
How come ?

can you describe your meaning of a lot there? for me if I use this phone a lot, it will only last 8-10 hours! for constant gaming it maybe will only last 2-4 hours!

only the moto raz maxx will last longer then 4h constant gaming.
alot for me is about 10 calls, 20-30 messages, wifi,data and sync on at all times. navigate during work, check rss feeds and email a couple of times / hour. play wordfeud and rumble with notifications.
maybe im not as heavy user as others but thats alot for me and i dont feel any change in batterylife from my meizu mx or htc desire. u get 2150mah battery in this phone, compared to meizu mx or desire with their 1500-1600mah but u also have double the performance and alot bigger screen, why would it last longer?

LG states that some apps cause battery drain. I have read it in some internal b2b document from LG site. One of the apps mentioned was poweramp. Don't know if problem is fixed with newest firmwares.

[Q] Battery life

Hello everyone,
I wonder how much battery life you have on i9000 with stock battery (1500mHa) on cm 10.1 with semaphore kernel?
Asking, just because I can only get max. 12h of battery life with cm 10.1 20130218 rom and semaphore 2.9.10, smartassv2 and row. Wondering is this normal or my battery needs to be changed. Any suggestions to max battery life on i9000 would be appreciated too
Sent from my GT-I9000 using xda app-developers app

The battery can last between 3hours and a week, depending on how you use your phone, so that's not a good question to ask.
If you feel that the battery is running out too quickly then download betterbatterystats and look for any apps using unusually high partial wakelocks or alarms and get rid of them. It only takes 1 rogue app to screw up your battery life.

I think he knows that.
12 hours uptime is not uncommon, especially when on 3g a lot. On wifi you should be able to get at least 20 h in my experience. If the battery is as old as your phone I suppose its capacity is not what it used to be, and you might consider replacing it with a sgs+ one f.i. - they come cheap nowaways!

That's in your experience, the way you use your phone.
Try playing NFS MW or something. You'll get about 2 hours on a gti9000. It varies far too much to try and tell people how many hours battery life they should be getting. Totally depends.

I use my phone for 3h wifi browsing, 30 min. music and 30 min gaming, but nothing intense. And with this usage I get 12h battery life. Flashed 2.3.5 stock rom. Still getting 18h max. So I think this comes to conclusion that my battery is old enough. That's why I asked for the battery life you get, because I didnt knew this is usual or not

My last for 2 days more or less depending on usage.

AW: [Q] Battery life
Guys i think its wrong to measure the battery life with how long your phone is working. i personally look at the screen on time it says more than just how long our device is working. I get always stats around 3h its unimportant if my Phone works 6h or 18h.

Time for a change

Hi All,
I have finally shortlisted optimus g and nexus 4. I have to finalize one.
Nexus 4: 16 GB, Optimus G: 32 G
Nexus 4 Latest updates, Optimus G: very slow updates( I meant very slow), and every small developing community ( i meant really very small)
Nexus 4: no LTE, Optimus G: Supports LTE (in india LTE not available)
Nexus 4: no USB OTG support, Optimus G: (Supports pen drive mouse keyboard u name it)
Both devices have reported back cover crack issues and over heating issues. Please provide your views on this.
Both looks good.
Howz gaming performance?
Nexus in india is 25k where as optimus g is 30 k.
So which one to go for.
Currently using Incs for almost 2 years, awesome build quality and pretty good developing community.

Well if I'm not mistaken the nexus 4 is based of the lg. So with that in mind I'd go for the nexus 4.
Nexus 4
Cheaper
Latest version of android
Not sure if, but will probably get 4.3 version of android
So go for the nexus

Yes we can convert n4 to og with a mod but lg abandons there devices once new device is out. Lg g pro is out.. Og2 is about to come.. So og will be a history. Very less development support.
FYI: the phone is available from august 2012 almost a year and just 38 threads in development section

hi guys, i need some opinions here
i'm thinking of getting an incredible s, as i got bored with the hd2 already
i liked incredible s because it fits right into my hand, and i liked holding it. here are my questions:
1) how is the phone? is it still fast for today's standard? (i'm thinking of using sense 4.1 roms)
2) will the speed of the rom increase if i use class 10 cards? my freind used a class10 on his nexushd2 ics and he said there's a noticeable
performance jump, but im skeptical
3) will there be any issues if i used sun global batteries with custom roms? i heard a while back that third-party batteries aren't compatible with
custom roms
thanks for your time yeah?

The Incredible S is a great phone but I think that in this current time and age, you can do a lot better.
For question 2, ummm, there is certainly the possibility but I think it would only be faster in regards to the activities related to the micro sd card. I think someone else should help me here. :laugh:
For question 3, batteries don't affect a ROM's booting and compatibility with custom ROM's. They are just batteries (like the stock one HTC gives you) that provides juice for your phone.

You always need battery calibrations after flashing a new rom as you flash a new rom, old battery stats are still in your device and thus this can affect your battery percentage.
As a new battery is already calibrated, it is not advised but it wouldnot make a difference unless the battery is too old or of low quality

They are not always necessary. 80% of the time when I flash a new ROM, I don't bother with wiping battery stats simply because it does not make a notable difference in battery life or readings whatsoever. I only calibrate battery if and ONLY if I know that I'm supposed to be getting better battery on a particular ROM

How many times does it take for people to realize that wiping battery stats is probably just as useful as trying to unlock the screen by screaming at it?
If you need the sources for why the battery stats doesn't matter at all, just look through my earlier posts Google it. I'm currently on 2G so it'll take ages for me to find it.

After flashing a new rom, there are always chances that some stats from previous rom are left and this could result in quick drainage of battery. Battery life isnot improved or made better by this, however, sometimes due to flashing roms, the battery percentage is messed showing wrong percentage all the time. Thus, Calibrating a Battery is a better than waitng for battery to settle down.
"Better performance and battery-life is why most of us turn to custom ROMs. We keep trying from the available ROMs and stick to one that meets up to our expectations. Now there are two ways to find out how the battery performs- with the help of a battery monitor app (stock or third-party) and by taking note of the battery performance during the hours of a day.
If you feel that your device is not yielding good battery just because the battery monitor stats show it, you might be wrong in your judgement as most such apps sometimes lie to us.
Remember that with any ROM installed on your Android device, you will discover two things: 1. battery heat up, and 2. battery drain. And these issues for the most part are due to process of your phone’s new software and battery sync. It usually requires 3-4 full-charge and discharge cycles before things go to a normal state and after this, you will notice great improvement in battery performance. So, do not be quick in concluding anything about battery.
Let the battery calibrate and while you wait try one more thing. Whether you get a new phone or new software on your old device, avoid putting your device into charging mode frequently. Turn off the phone, plug charger, wait till it is fully charged and then use it till it is fully discharged. Repeating this several times will improve the battery-life of your device. I have tested it and it really works. "

whoops i mistook battery calibration as wiping battery stats :silly:
but yeah, honestly, my battery rarely falls below 30%. Im more of a go home then walk out a couple hours later so charging from 5% takes a bit too long. Thus I never do battery calibration. In addition it doesn't really do anything. Battery does not improve to a noticeable point where its actually worth the 5 or 6 hours wait to charge the phone :/

Best or ideal kernel settings for best battery life with good performance?

The title explains it all—I'm wondering what the best kernel settings are to achieve the best battery life without completely dropping performance. I've never tweaked the kernel on any phone I've owned before, so I have no idea what those settings might be. I currently get around 5-6 hours of SOT, which is great for heavy usage but with a battery those huge we should expect way more.

I'm currently playing around with majorly under clocking the CPU (Currently testing at 1.2 GHz) and have yet to notice a difference in performance. I'll update with battery improvements if any arise.
Sent from my DROID Turbo using Tapatalk

im on zzmove with profile 6, run only 2 core at 2.4Ghz and every thing seem good
phone run cool and great in game(framerate still good and more stable since no throttling at all, before that with stock, my phone get hot and lag if i play asphat for long) not sure about battery yet but seem good

Try computerfreak ROM, i'm getting 77 hrs on battery and 6 SOT!

Oops just now noticed I had replies.
I'm currently running Resurrection Remix and I seem to be getting better battery life than I was on stock, which is odd; however, I wish to get more. Update me on those kernel settings.
Also I noticed that when I'm at school the cellular signal drains my battery considerably. The signal there is poor, is there any way I can minimize the drainage?

That's a ridiculously easy thing to do, I can't believe I didn't think of this. However, its rather inconvenient. Any other ways? I heard back in 4.4.4 that there was a way to disable certain bands or something to consume less power when you have bad signal.

I'm on rr and honestly I'm not getting the best battery. Like 3.5 hour on screen time. It does still make it through the day though. I changed the kernel settings to conservative under cpu, which helped a lot from previously getting under 3.

Settings, configs, performance tuning, kernal tweaks, then in the app in the cpu tab, the cpu governor option. That's where I found it and I turned it down and I'm getting better battery.

That's odd. I get considerable better battery life on RR than I did on stock. I've hit 5.5 and even 6 hours of SOT with heavy to medium use (when I'm not at school at least).

Same here, but I noticed it lasts much longer with Greenify and Amplify installed with Xposed. I lose about 2-3% during standby mode during the night....whereas before I lost about 10-15% even while on RR.

Just got 7HR and 4 mins screen on time with in 2 days didnt use my phone at school only when i was at home so i guess 7hr's is good..

That sounds right about what stock should be getting for some users. It's good to reference stock with your personal use versus someone else.
1 hour of a playing a game with full brightness will use significantly more battery than an hour of book reading on night move although they both technically have the same screen on time.

I usually consistently got about 5 hours and 30 minutes of screen on time on stock with medium to heavy usage at school and at home.
On Resurrection Remix, I usually get 5 or sometimes 5 and a half or 6 hours, with heavy usage at home. On school days, I can only manage to get around 3, which I find incredibly odd. I chalk it up to the poor signal at my school draining my battery.

You can get 48 hrs on the Turbo. You can also get 5 hrs. Like I said before, it all depends on your personal usage. Perhaps they have a baseline test they do on every phone so there's no variable aside from battery.

I do so much work on my phone so need one that is smooth and quick with great battery. I have Pure Nexus now and it's fine but sometimes it seems to lag. Maybe they all do when jumping through lots of apps. Maybe I need to reboot daily to keep it smooth.

I don't think it should lag but you may give custom kernels a try.Lag sometimes happen due to throttling after heat.Custom kernel manage these issues at ease.

OK thank you. I have 3.10.40-PureKernel-Shamu-2.04 so it's a custom kernel meant to work fine with PureNexus I think. I'm sure it's just because I'm using nav, and other high usage apps.

IMO android uses a very smart way of managing stuff when multi-tasting to reduce lag.So it is still highly doubtable.
Why don't you try some other kernels and overclock possibly?

Right now the phone doesn't last till much past 6p so I don't want to clock even more in case it uses more battery. It used to last longer so maybe when updating to 7.1.1 with the newer Pure Nexus that took some more. Or maybe it's just a 2014 phone with high mileage =). I used to go to sleep and overnight it hardly used energy now I notice when it's just idle it can use 20% overnight, maybe more. It could be an app I downloaded is running.

Awesome thank you for that. I'll probably give it a try. I think it was in the top 5 custom roms on an article I read.

i finally switched to 7 on pure nexus...it's great...smooth...fast...had it running almost 300 hours without a reboot and it was still going strong...i haven't tried nitrogen...so can't say...but am happy with pn...i came from chroma rom...

Roms, Kernel, and Age are all irrelevant!
A phone will last as long as the battery allows, and that's based on your usage of the phone. Period!
You use a lot of apps, it's going to die quicker.
You stream a lot of music/YouTube, it's going to die quicker.
There is NO magic combination of Rom+Kernel that is going to magically make your battery last longer.
Your battery has X amount of usable stored electrical charge, and your phone will use it accordingly based on what you do on it.

So you're trying to say using Rom and custom kernel can't help increase the battery backup(SOT) of a device?

I don't think he understands or maybe is oversimplifying what he means. The Rom and the Kernal which affect the amount of systems running will affect battery life. The age as in the amount of times you've discharged and charged your phone over months and years will affect the battery life. There are tons of variables that affect it. One can say the kernal and the rom if they are running more systems or less then that's what he means by saying if you use more apps then it uses more battery but that isn't magic that's just use. So if you put a certain kernal and rom then that is affecting what you do on it which affects battery life. The X amount of storage a battery has degrades over time. The first answer when googled is below. I probably have almost 1000 charge cycles now. Nothing I can do about that.
"Charging a battery forces ions from the cathode to the anode; using the battery reverses the flow. Over time, this process wears out the cathode, which results in reduced capacity. A high-end lithium-polymer battery can lose about 20 percent of its capacity after 1000 charge cycles."

Not if you have a bunch of garbage apps running in the background, constantly running some kind of process to check for incoming messages/app notifications/location tracking.
You wanna know how i went from having 10% battery life at the end of a work day to having over 50% battery life???
I stopped installing **** on my phone that i didn't absolutely need.
And low and behold, my battery life "magically" increased itself.
