Yet, another battery life thread?

Hello,
I know all of you have heard this time and time again. I'm sure I'm going to create a huge battle discussion, which I don't want honestly. But I've searched throughout the forums with no luck, and if I've missed this, please direct me and delete the post. So, with that said, hear me out..
I understand apples iPhone's battery tends to last long because of the not so true multitasking, and there are hundreds of ways to make androids battery life significant.
I was just wondering if there was any ROM, kernel, etc to get rid of the "android true multitasking" to increase battery life. Myself as an android user, never tend to use widgets or really have any use for multitasking anyways. I play on facebook, text, and make calls periodically. Anyone want to chime in without blowing my head off on this one?

ICS and JB both have an option under settings/developer options called Background process limit.

Does this increase battery life, that you know of?

Really? Doesn't seem like it would or even that it would increase battery usage since apps have to be restarted every time.
It will definitely free up ram, but that's not really an issue with the GNex.

I should probably also state that I'm on Vicious CM10 w/ stock kernel, and have not yet seen more then 10 hours and 2 hours on screen time.

For my opinion I think depend on lifestyle you use phone

True, but I only use my phone for browsing facebook, xda, and text messaging. I never play games, use youtube, netflix, or any other battery drainer. I also keep 4g off. I would think I could get more then 10 hours and 2 hour screen time with the 2100 mah extended battery (already exchanged for a new, so it's not the battery)

One hour on regular battery

I must be doing either something really wrong or else...
My battery last me a little over one hour on standard battery (original rom+root) and that's me even using lean kernel. I've seen on forum some people were able to get as much as four hours of their screen why is it with my phone I'm only about to do so little?
What's the best so to see what's going on with my phone, who eats my battery, which apps are doing something that they shouldn't.
It really is killing me, I want to be able to enjoy my phone longer.

It is normal that the screen uses a lot of juice. What is more interesting is which apps are on 2nd and 3 spot. Do post screenshots if you can.

I will post pictures later, but here is quick overview:
#1 is _ALWAYS_ : Screen
#2, #3, #4 and #5 is: Phone idle, Voice calls, Android OS, Cell standby (not in order, so i took example from several screen shots that I saved)

do you have a terrible signal where you're at? does it jump between LTE (i see you have verizon least based on your image under your name) and 3g alot?

to save power I completely switched over 3G (by turning off 4G (LTE))
on the top of that whenever I can I always switch WiFi on to switch to WiFi instead of 3G and whenever WiFi is not available I always turn it off.
and here is a kicker: I also use Ultimate Juice Defender (w/ pretty aggressive settings (turning data on only every 15 minutes)

Why is my battery "done" ? I blame Sandy as before that it was fine, I'd easily do close to 2h of Screen time (at least 1h30m), now after Sandy due to reception that I'm getting right now I think that's why I'm getting so little now..

Seems like you got it all figured out then.

Man, I'm not from the US, but if Sandy came by my town, i guess my screen on time would be the least of my worries. Lol, can you imagine what damage it may have done (more than likely) to the cell towers and radio equipment?

it's not like Sandy moved in or anything... Sandy is already gone and people (including me) heavily rely on their phones to communicate with others and so am I, so I need my phone more then I did before and if it's dying half way through the day that's a problem for me.

Your awake / screen on ratio looks pretty nutty to me. Basically your phone was awake for 4 hours, and your screen was on for 1 hour. Titaniumbackup kept your phone awake for 38 minutes; why is that?
Sign out of any google services you don't use like Google Talk and / or Google+.
Turn off location services and only turn it on when you need to. It's easy to toggle this by placing a Location services shortcut on your homescreen. This, for me, has had the largest impact on my idle battery usage. With location on, batt would drain around 2 to 3% per hour. Now it takes 3 hours idle to take the battery down 2%.

I think Titanium Backup was doing backup and then uploading it to Dropbox (happens once or twice a week at night)
Google Talk and/or Google+ is closed (and even cleared from recent task upon completion of using them)
location service I use, I'm sharing my location with some other people, but i'll give that a shot to test it.

[Apps] "Snapdragon™ BatteryGuru (Beta)

Just installed a battery saving app from snapdragon..
https://play.google.com/store/apps/details?id=com.xiam.snapdragon.app
Has someone used this app for a while... please share experiences and comparison with other apps like juuce defender.
Sent from my SAMSUNG-SGH-I747 using Tapatalk

I just downloaded it to see how it does compare to Juice Defender and DS Battery Saver Pro. I never really like Juice Defender and have been using Battery Saver for a month and it seems to help my battery life.
Once I have been using for a few days I will report back what I think about it. Thanks for the post tho otherwise I wouldn't have found this app.

Just installed this.... will report back when it's done learning and switches to saving mode.

Thanks for the heads up, i'll give this a try.

nice grabbed this up will be checking it out.

Just posted this in the Verizon Galaxy S III forum as well.
Still seems silly to me that we are going to have to have 4 separate discussions for an app that will work the same on each carrier.

I'm not really sure on what the value of these apps are.
Letting my phone do whatever it wants when I'm on wifi and my phone is sitting idle, my phone uses around 1%/hour of battery life.
Some portion of that is all this app could really save then, right?
Why bother if, in exchange, I'm possibly having delayed notifications, apps not updating in the background, etc.?

I've been running this app .today is 3 day (around) have not rebooted or anything using phone as always honestly don't see a difference yet..

Let us know how it fares against JD and BSP. I have JD Uktmate and have been happy with it. I lose about 1% an hour at night which is better than the 3% I was losing prior to purchasing JDU.

doesnt do anything, i get about 12% drain in 9 hours when im sleeping, what it does just turn off wifi for me if im not in range, which is useless, having wifi on doesnt drain much battery at all

Thanks for the link! Will update in a few days with results

can't tell if it's just a placebo effect or not, but i feel like my battery life is a little better after using this app

I haver never once had a random reboot until I installed this today not sure its related just throwing it out there
Sent from my SGH-I747 using xda app-developers app

After using this for the past few days I would say overall it is not that bad of an app. I am really starting to like it. My average battery usage went from 5-6%/hr to 3-4%/hr. I know there are a lot of variables that go into this but I would say it works as well DS Battery Saver. I have also used JD but never really liked that app. I will continue to use this app to see what the long term would be on here but its a good find in my opinion.
If nothing else try it out for a week or so and compare stats. I use Better Battery Stats to get my info from.

Has anyone compared this to the relatively new "Greenify" battery saving app?
http://forum.xda-developers.com/showthread.php?t=2155737
Anything that suggests it saves battery makes me nervous. Because the only way to do that is to shut down apps. And when you shut down the app, it may not get updated, or it may open very slowly when you do need it, etc.

I did not like it much... i am guessing that all this app does is change sync frequencies of different apps. To do it it tries to determine your location so that it can turn sync off/on or change sync interval based on your prior usage patterns.
Once it was out of learning mode, i noticed that my s3 battery drain was quicker due to excessive usage of maps by this app.
I uninstalled the app... and have got my battery life back.

Carrier IQ on AT&T Note 5

I've been monitoring my battery life for a while and while I get pretty good battery life and SOT, I noticed that Android System always seems to consume the most battery. I've looked at threads where people are getting absurd SOT (upwards of 7-8 hours) and wondered why my AT&T model couldn't do the same even after using Package Disabler Pro and Adguard and I think I know why. I went into Application Manager --> Running --> Android System and found this (see attached image). It appears Carrier IQ is onboard again and causing Android System to consume a lot of battery life. I believe this is the reason why some aren't getting great battery life and unfortunately it can't be deleted with Package Disabler Pro.. I wish Samsung would stop letting carriers tamper with their software or release a pure version of the phone that's compatible with the AT&T network. Sorry for the Novel but I wanted you to know why you are not getting great battery life.

Thanks for the tip.. Can you try it out and see what it affects? Don't wanna turn it on and it breaks a bunch of stuff. I use Adguard, Google Now and social media apps so I'm wondering if that will break anything or stop anything from working properly
Edit: Did some research and it turns out that it affects multitasking and might actually drain more battery because when you open an application it has to reload everything from scratch since it was shut off and can end up draining more battery than it saves.

terrible battery!

the battery on my nexus 5x is very poor. battery saving apps do not help, neither does a custom kernel and using powersave mode, etc (that only made performance worse, no improved battery life). I'm always worried about my phone dying when out and about, even if i don't use it much (and sometimes i really need it!). any suggestions?

There's nothing that will dramatically increase the battery for you on this phone. If your achieve poor battery statistics with the stock rom, it's time to move on. Get a new phone.

Why was your phone constantly awake while the screen was off? Wakelocks, my friend. ...Unless you listened to music for 14 hours straight.

You probably have "Wi-Fi scanning" activated in the scanning options within the location settings (in the three dot menu). I'm not sure if it actually has a big impact in battery life, but I usually disable it, because, as far as I know, as long as I enable Wi-Fi, it will still use it to improve location.

Yes I looked at it too, I downloaded when i caught WiFi connection wakelock detector, and here results:
Screen wakelock (camera, because double power to run, So thats not weird)
And cpu wakelocks
Music was only about 2-3 A.M, later about 3-4 hours, but thats not on battery usage, but on wakelock detector already is noticed
P.S WiFi scanning in 3dot menu i had turned off, but it still on battery usage is as on, but took not so much battery (13 mAh) so I would keep it away

i also had massive wakelocks, seems like apps like facebook and viber has wifi modes that override the phone ones.
