[Q] Undervolting support for the omap3? - Moto 360

Man I love this watch, but the battery going out by 8pm just as I walk in the door to home is getting annoying. I've been looking for ways to extend the battery life without reducing functionality (aka I don't want to turn off ambient mode lol). Now, I don't use fit at all, so that's gone, and im asking sure to use a watchface with a white background to reduce active pixel drain.
One final trick that I've been looking into is a kernel with undervolting support. However, perusing the Dev forums turns up dry for this feature, despite the fact that we can unlock the boot loader and flash what we like? Kinda curious why I can't find a way to do this. Did TI make it absurdly difficult or what?

Someone would have to write a custom kernel for this to happen. Not sure if the kernel is open source, i have a feeling its not. Even if it was, a good custom kernel takes a lot of knowledge and work to write. Undervolting would also not make a big impact in the battery life of the device.

Better battery life with kernel?

I have been rooting for years but I never bothered to really mess with kernel settings to increase battery life. All I'd do is over clock or under clock. What do you guys do to increase battery life? Like for example, lower voltages? I have no clue exactly how this works. I'm kind of tired of carrying 2 spare batteries around lol I'm on Franco's kernel with the hot plug enabled from his app but I might switch to imo's. Anyone wanna be kind enough to help me out please?
I just got a 200mah battery and its animal.
Before I used APEX kernel and took the usual steps, dimmed the screen etc.
Thank you for the response. I'm sorry, I should have stated that I'm on the CDMA version lol
I've been considering a custom rom/kernel and reading up on them a bit. I'm pretty much a n00b, so maybe this is nothing new to you, but it seems that controlling kernel wakelocks and specialized cpu governor settings + undervolting are the main things that increase battery life. I think minimizing unnecessary wakelocks seems to be the main key.
For the most part, battery drain comes down to two issues:
1. Screen use (not much we can do here)
2. Radio use (which tends to wake up the phone unnecessarily, I think)
I think the radios -gps/voice/3g/4g - is what causes unnecessary wakelocks on stock rom/kernel - as I get virtually no, nada, zip, zilch, zero sleeping drain in airplane mode.
If your battery drains 1%+ an hour just sleeping, it can add up significantly. Even when things are turned off, they still sometimes cause wakelocks. Take NFC for example, I just read in a forum post that it was causing wakelocks even when turned off.
Question
Do you guys think since in AMOLED displays the black color is essentially the pixels being turned off, having a black wallpaper uses less battery? because each time I check my battery usage I see that my display is always on top, and I have this theory can anyone confirm it or correct me if I'm wrong?

Battery Issue ! Its the 7th Charge Cycle Now

I bought this amazing [As you all know how fast it is ] Galaxy Nexus and was previously using hTC Desire S[GB] !!!
I'm somehow not happy with the battery life and also the overheating of Nexus !
It is Stock[ROM + Kernel] + Root ! around 7th or 8th charge cycle !!
I did try out Cpu Sleeper App works like a charm but was facing reboot issue and that is why had to remove it !!!
See if anyone of you could help me overcome these issue ! or Is this really something for me to worry about !!?????
[PS: Please don't recommend me to change ROM or KERNEL ! Because I prefer to stay on Stock ! Also NOOO Overclockig !]
Check out the Few screen shots i took when my brain kicked me to !!!
We need to see the screen before this one(the one that lists top consumers of battery). To see if something is waking the phone up. Also, charge cycles and calibration are bogus. If anything, you would be using the phone less since you've finally set everything up the way you want and the newness effect has worn off. My battery life has been about the same if my usage pattern remains like it usually does throughout the day. It doesn't really look too bad, but the drops seem a little steeper than what I normally see. . Grab CPUSpy and BetterBatterystats. I'm on my way to work soon, but someone may be able to help you before I go on break.
the screenshots you required

Here we go
ok so calibrators and cycles are bogus ! I get that !
What about brightness ? Should that be auto or manual mode ??
And is Google Now causing issue ?? Because its not really useful to me on daily basis !!???
And any other suggestions your would like to share
I was gonna edit my post, actually. I've personally never fully charged and drained my battery for any of my phones(some people swear by it though). I guess if the readings are out of whack then yes. My phone got stuck at 85% for almost 12 hours one day, but I had did something which messed up the OS. Haha.
If you don't use Google Now, you can opt out of it. Brightness is a personal preference. I usually stick mine at 25%. Auto may take a hit on the battery, but I doubt it's anything to worry about. Just the common sense stuff. Apps that poll data in the background will drain the battery, but if they're properly coded, they shouldn't be a problem Running on 4G/LTE/HSPA with a bad signal will drain it more since the radio is trying to find the best possible signal. After a full day of use, what is your typical screen on time? 18 hours is pretty good if you're using it on HSPA all day.
ya honestly that doesnt appear to have anything wrong. What results were you expecting vs what you have? You have a lot of screen on time, that takes a LOT of battery to run the display and using it when brightness is high takes significantly more. Also it appears you have a couple long phone calls in there as well. As far as heat goes, youre going to have that on the higher end phones due to the gpu producing heat and oled displays produce a bit of heat as well, lcd runs cooler.
Weak/unstable/unrealible mobile network signal could cause the fast drain of your battery. I saw you have one bar of hspa signal in the 3rd screenshot.
Those graphs should be much flatter during idle periods. Something is keeping awake. If you're on jelly bean its prob Google now. It does it to everybody.

Actually 3G isn't really well established for Vodafone[or any other company] in India.Also there is a peak going upwards in the first image indicating charging and after having a battery life of around 20 hrs on My Desire S and screen on [appx.] 7 hrs , I'm very disappointed with Jelly Bean !! Also While googling this issue I found out that somebody sniffed the mobile wifi connection to monitor and found some app constantly exchanging packets which according to his test was the root issue for the battery drain !!
Edit:
]Ok I found the way to shut google Now !
I'll records stats for a day or two and get back Thanks Everyone for your time and help

In Google Now >> Menu >> Settings >> Google Now there is an on/off switch at the top. Depending on the ROM it's included as either velvet.apk or QuickSearchBox.apk but removing that would get rid of Google search I think.
Yeah. I think its actually part of search. Like I said, just opt out and you should be good to go. Keep us posted.

[Q] Why are YOU obsessed with battery life on your SGS3?

Okay I have a question for the masses here. Why are YOU obsessed with battery life on your SGS3?
I've been through my fair share of cell phones with the latest 3 being the Galaxy S, SII and now the SIII. I've been through a long list of custom roms as well as time spent on stock roms and not once I have I installed a battery monitoring app like Juice Defender, nor have I been interested in undervolting or underclocking as I don't feel the extra battery life outweighs the instability of the phone and the time spend finding the exact perfect values to prevent reboots. As long as I have battery life to get my through the day (which I always have MORE than enough, I'm happy. I'm not a heavy user but my phone gets a workout during the day and I'm never far from a charger which is the awesome thing about having a USB connector to do the charging.
So I ask the question, what is the obsession with battery life? Are you trying to go green and get the most between charges as to not waste power recharging? Do you use your phone so much during the day that you can't make it through the school or work day without it going dead? Are you off the grid living in the bush and only get to charge when you are in town every couple days? Is it bragging rights you are looking for? Why did you spend big bucks to buy an extended battery? Why don't you use the phone the way it was intended to be used and turn off syncing apps just to save a bit of battery? Why do you turn screen brightness down to minimum and leave it there all the time when we have big beautiful screens that look so much better when they are correctly lit up for our surroundings?
I just find it interesting that every ROM thread and every kernel thread and a good portion of the threads in Q/A sections are littered with questions and discussions and arguments about battery life. How to get better battery life, why is my battery draining so fast on such and such rom, what is a good screen on time amount per charge. I don't understand nor can I find an interest in spending time to dissect and analyze everything just to squeeze an extra half hour of screen time out of my phone.
So why? Why are YOU so interested in the battery life of your phone. I'm not looking to make fun of anyone here. Just curious what the obsession is all about and why you are so interested. How does it make your phone or your life easier and better. Maybe I'm missing something.
Well for me, my battery life really sucked and didnt understand why so I started researching and i found out from stock you can do tweaks to improve it and so on and so on.
When I say my battery sucked on stock though it was really bad. I couldnt go a whole day. I would get about 10-15 hours of on time with less than a hour of screen time and my phone would be dead.
I dont care for going 2 days without a charge, I just wanted to go morning to night and still have some juice left. which i wasnt able to do before.

Actually, battery life can have quite a few hours difference depending on your settings, apps, kernel settings and ROM you run. So yes, it does matter if you can get 3.5hrs on screen instead of 1.5hrs.
People don't want to have to carry their charger with them all the time in fear of their phone dying on them in the middle of the day.
For me it is just the simple fact that I can run my phone for almost 2 full days without a charge (not kidding either). But I would venture to say that for most, it is because of the whole reason why many are here. We're Tweakers and no I don't mean Meth addicts. We do it because we can. I don't undervolt at all but I do overclock my kernels a bit (not max) but have found a really nice balance that will give me plenty of time using my phone and not having to worry about charging. Yup, I use my phone.
I smile to myself when I see these screen shots and the line is smooth and flat. Not sure if you are a skier or not but a good analogy is if you see a Double-Black Diamond (expert/steep), there is something wrong. If you see a Blue-Square (intermediate/nice slope) then you are good to go. Green-Circle (begginner/very low gradiant) means that noting is running.
Btw moving to Q&A
I feel the same as the OP. I don't OC/UV for pretty much the same reasons. I don't care. I have run Juice Defender in the past on stock setting values because I was basically lazy and didn't feel like tweaking the sh*t out of it to get the "best" battery life. Not to mention I don't like that it literally turns off your cell radio and initializes it in incremental intervals. I have actually been running an app called One Power that is free on the Play Store and have found it does improve my battery life mostly when my device is idle. But I, like you, am hardly obsessed with getting the best battery life. I don't use extended batteries because I hate how they make the phone twice as thick and I tend to avoid anything non-OEM for obvious reasons. I'm basically happy if I can get through a day on a single charge. I do have a 2nd OEM battery I keep charged in case I don't have time to fully charge up. Our expectations of getting days worth of use on a single charge is just ridiculous and unrealistic. If I cared that much I'd switch to Verizon and get a RAZR Maxx. But that ain't happening anytime soon! Besides, not all phones are created equal so - what works for one person may not work for another. I feel discussions of battery life in ROM development threads are a waste of time and serve only to clutter and detract from development of the ROM. Apps, use, etc are huge variables and will vary greatly from one user to the next. So, when people say "battery life on this ROM is great!" I usually roll my eyes and ignore the post.

Hey, can you shoot me a PM with more about that App. I'll check it out tonight but can you give me more info on it from a real-life user and not some Market desc/review.
Also, report those stupid posts in the Dev threads and we can delete those. I saw one the other day about 5 hours after a ROM came out (new thread and all) stating that the battery life was "Awesome!!!". How in the heck could you know after 5 hours of the ROM being posted (he was not a tester either), let alone being flashed. Rediculousness.

Sure. I just use the default settings the app comes with but you can tweak it to your liking. Will send you a PM shortly.
Edit: I couldn't agree with you more on the battery life postings 5 hours after a ROM has dropped. That's absolutely ridiculous and impossible to gauge so soon. You gotta give it at least a couple days to be able to accurately judge the battery life.

I'm generally indifferent about battery life and attempts to prolong it for 2 reasons.
1. The settings and customization done by the manufacturer are stable values tested and balancing between battery life and the features of the phone.
2.Everyone know what they're getting jnto when they buy a phone with ~4 inch screen,has LTE and top of the line features. It's rather obvious that battery life won't be great, if it isn't then you might as well just go back to the candy bar phones, if you expect the best and the newest AND battery life.I certainly didn't expect my phone to run for 10+ hours when I got it... and besides buying the best phone on the market and then turning everything off to conserve battery life just defeats the purpose. Just buy an extended battery, buy the extra battery OEM and bring a spare along, or have an external charger as well as a 2amp usb charger.
Edit: When I initially got the phone, it was getting 6-8 hours on a charge after a couple of months 12-14 hours per charge. The same thing happen on the JB OTA, Im getting between 10-18 hours depending on my Reddit, Twitter, Gmail and Engadget usage, though I have to admit there are sometimes problems with some apps preventing deep sleep and occasionally what seems to be memory leaks with apps constantly using the data connection.

I like pushing it to see how far the battery can go. I could make it through the day before, but with some compromises. I bought an extended battery and flashed a new rom (which came with some good kernel settings to mess with), and now I can keep everything on and go two days without a charge.
For me it's more about getting what I'm used to--recently switched to gs3 from an iPhone 4, which had amazing battery life. I got around 8 hours screen on with that and initially only 3 with the gs3. So I tweaked away and now it's back to what I expect!
Edit: also I tweaked my way to better battery life because I can--why settle for something that could be better?

Hello ,
That's my first days impression about Xperia S !
any advice plz about improving the battery life please ?
Give it a weeks worth of charges to get going.
although screen brightness and 3G have the biggest impact on battery life

Thanks for your response , I will give it other chance and see what will happen
By the way screen brightness is nearly 40% and 3g is off
with every thing is off the battery may survive , but hello SONY GUYS , I didn't buy the phone to disable all it's abilities !

You might consider to check out some other threads before complaining about the battery life. There's many available so browse a bit i suggest.
Tips, Tweaks, and many other good information available on battery life extension. Search, you will find those.
And definitely the battery back up should increase after at least 7-10 days of use.
had the same impression when i first got my sxs, but after about a week or two, and a few tweaks it's pretty good now (1 1/2 day with normal use)
for the screen keep it between 40-60% brightness, especially if indoors. i only set it up to 100% when im outside at long periods of time,
switch off 3G/mobile data when you're not using it, and switch off "account sync" if you're not waiting for some important email etc. 3g/mobile data + account sync will kill your battery really really fast, so i advice refreshing apps manually.
i did some research and its fine to keep nfc open, since it uses very minimal battery WHEN it needs to use the battery which is pretty rare (unless you pass around a lot of data via nfc the whole day, which is pretty unlikely).
if you want to go the extra mile, unlock your bootloader, root your phone and mix and match with different custom roms / kernels that optimize battery life.
A very useful trick is to use 2g when you don't need 3g, it saves one hell of energy..
No idea what you're talking about. My battery goes for almost two days with 3G on all the time.
just use it for two weeks with normal charging. and if i were you, i wont unlock it until two weeks (but i have unlocked mine the first day i bought it..hahaha..),
why do i say this, so that if there are problems occur within those weeks, you can return it without problem.
and you will have more time reading and understanding anything that can be done with your phone,
see my signature "Read ME" for head start.
It's because you've just got it. Is it even updated to the latest software? And you've probably been dicking about with it non stop so of course you'll hammer the battery

Disable Auto Sync, apps like skype / viber are also hard on battery.
You may also try "Deep Sleep Battery Saver Pro" app.
Thanks for you all , I will try every advice written here

[GUIDE] Getting the best battery life

Hello,
I've been using this device for about 5 months now and the battery life for me has been great so far, but there's so much you can do when you need the juice in your battery last longer. In order to help those who want to get the best battery life out of their phone, I've compiled a list of things I do to make my phone last longer.
We'll go from the things most effective to the least and mind you, all of these can be done without rooting of using ADB etc. So let's start
'''Turn on Gray Scale'''
As we have an AMOLED screen, turning on grey scale will give you an improvement in battery life of around 25-35 %, and it's especially noticable if you use your phone in high brightness mode.
'''Dark theme'''
Dark theme obviously saves battery on our phone, there's and awesome guide on XDA guiding you to do it without rooting or using any theme engine.
'''Set brightness to 50%'''
Our eyes don't perceive brightness linearly, so 100% brightness will take around 50-70% percent more battery than 50%, but going much lower won't help either cause increasing brightness from 0-50% results in around 20-30% extra power draw.
'''Restrict background running of less used apps'''
You can restrict an app from running in the background and this setting is baked right into the App Info settings,
Go to app info and tap on battery usage, from there, restrict the app.
'''Enable data saver'''
This can be enabled via Quick Settings menu and this can drastically save battery if you're mostly on Mobile data.
'''Turn off Auto Sync'''
It is long known that doing this can save a bit of battery.
'''Enable Battery Saver'''
Pretty self explanatory.
'''Change minimum width'''
Set minimum width to anything less than 400, this leads to less information being displayed on screen which results in lower usage of GPU, and thus better battery (somewhat)
'''Reduce animation duration scale'''
This will speed up everything and improve battery life just a bit.
And that's it from me, if I remember anything else, I'll make sure to add it, and please make sure to tell me anything that works for you, I'll happily add it.
If you want to get absolutely the best battery life out of your device, you must install a custom kernel. I'm using Fenix currently.
Also, turn off printing service. This idiotic thing is turned on by default. It keeps sucking battery for no reason at all. I'm not using stock ROM now but you can find it by going to: Settings>Bluetooth & Devices (or something similar)
Can you post the link of the thread for enabling dark mode I would like to try that.
Another tip - switch to airplane mode, mobile network is one of the biggest battery consumer..
But seriously, how does greyscale mode save the battery? Instead of glowing one of the subpixels for displaying a color, all of them must be shining to provide different shades of white color. It might even use more power.
Width change and animation duration scale have some very interesting thinking behind them, it will have absolutely no impact on the battery.
Dudes, just enjoy and use the phone. Why do you want to cripple your experience just to gain extra few percents of battery per day? If you're living of the grid, there are much better phones for such a lifestyle.

There's an XDA article comparing battery saving with AMOLED on black and grey theme, you might want to check it out, or you can also watch a video by Mrwhosetheboss to see how it went for him. As for animation speed and DPI, they have the least effect on battery life as I've stated above. Kindly do some research before you start making claims.

Where exactly in the article does it say that monochrome display saves power over colored one? Actually it's you who started with unique claims, so please provide some proof.
