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.

Did not know that. Thank you.
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)

Battery draining at 1% every 2minutes, help!

Ok guys, so i got my replacement siedio 3800, and after charging it initially for 12hrs, after I got it. The battery issue is still here. When the phone is not on, or standby, it is fine, however while using it, the % ofbattery life just keeps dropping, 1% every 2minutes about I timed it and averaged it. I checked GSAM 29.5% is used by apps, i have only 3g enabled, no wifi, bt, or gps. Plz help me get this fixed, same problem was with the Razr maxx. I am using Bamf JB rom. About to throw the stupid phone lol!
And i do have full 3g/4g, but only 3g enabled, with good signal strength

if you're saying it happens on your maxx as well... you have a app burning your battery

Find the app
Delete non essential apps

god is the creation of people with nowhere left to turn

how do i find it? i am stock bamf jb , with gapps, thats all, and under battery, no apps are burning a lot, web browser was 6% was the most. and GSAM said only 29.5% of battery was apps

could it be google talk, or aim? i usually exit out of both when done. But google services is always on in running apps, but didnt want to disable, wasnt sure if that was for gmail. auto sync is off

What do you mean stock BAMF? BAMF is custom ROM and rooted... If you ARE rooted, easy. Download betterbatterystat from Play Store and see which app drains the battery the most.

is gsam the same type of app? It says apps are using 29.5% and browser is highest at 8%. I really dont want to pay $3 for the betterbatterystats

then go back to stock. if the problems happens on stock WITH NO APPS, then you have a bad battery.
if it doesnt happen, you have a crappy app somewhere.

If you don't wanna pay, you can still download it from xda. The dev offers the app for free for xda users.

I had the same issue on BAMF. I could still pull out about 2 hours screen time on my 2100mAh battery but while the screen was on I could watch the percent drop.

How did you fix the issue? Also I disabled all extra apps so we will see. Otherwise does someone have a link to stock ROM image? Or another trick and tip

Hello. That is why people invented .apk files. Just download a .apk file. It is what everyone does.
Galaxy Nexus-codenameandroid rom

usually bad/rogue apps wont show up on those battery apps. I remember i restored app settings/etc for dolphin from 2.3 to ics and that was the cause. Removing data/cache and the app itself removed the battery drain.

Do a binary search of apps (install half of them, if it drains then the culprit is in that half, if not in the other half, etc etc).
Try to disable as much syncing as you can, and definitely disable instant upload.
Betterbatterystats apk from the thread that deeren linked to. cpuspy might also help.

imo you should perform a reset and start over.....its faster

Not everyone is self entitled enough to screw over some hard working devs, so your generalization justifying it is patently false.
Regardless, piracy and warez aren't welcome here. It's a quick and easy way to find yourself under the banhammer.

I didn't.
Use WiFi when you can it what helps me. I am now on Affinity ROM and got 21.5 hours with 2 hours 45 minutes screen time. With the 2100 mAh battery. I am using the Glados kernel it came with and no tweaks to it.

Trying to track down a rogue application is hard work, do it only if you feel like you're up for it.
Apps with good reviews and comments don't usually cause such a problem but checking per app reviews/ratings will take you, I don't know, maybe till you grow old.
Best thing to do is to reset everything and start light, with only a few apps, then install another batch of apps if there is no problem with installation of previous batch, this way you can find the culprit.
Good luck.

OK well I am back to 100% stock like suggested and charged my battery 10-100% overnight. Still losing lots of battery. 13minutes cut me to 94%. So it was the rom after 3hrs of getting back to stock. This is also my second siedio 3800 battery. What's next?

[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.

[APP] Snapdragon™ BatteryGuru.

*PLEASE SHARE your experiences and RESULTS here in this thread. Do bear in mind it will take 3 or 4 days to find out though!*
''Snapdragon™ BatteryGuru is a battery life saver app that extends battery performance and improves overall user experience by intelligently making changes that optimize device functionality in phones with Snapdragon mobile processors. This app:
• Delivers longer battery life with fewer charges, acting as a battery life extender
• Intelligently learns how you use your Snapdragon-powered smartphone and optimizes your device without disabling smartphone functionality
• Requires no user configuration - Snapdragon BatteryGuru automatically learns and adjusts the smartphone settings so you don’t have to
After a brief 2-4 day introduction period, Snapdragon BatteryGuru learns the user’s behaviors and then notifies the user that it is ready to extend the battery life and improve the experience. Snapdragon BatteryGuru continues to operate in the background, deepening its understanding of the user and further optimizing the experience over time.''
https://play.google.com/store/apps/details?id=com.xiam.snapdragon.app
The app seems a good for the average Nexus 4 user. I think. It certainly is polished
I'd like to know peoples experience and (improved?) results with this please. I can barely get out of the learning phase as I keep updating my device ROM so I know it will be frustrating/useless for many...
People seem to be very positive on reddit and elsewhere which is the only reason it's caught my interest. Beta results for some are impressive at least. Others less so. Hopefully posting some ACTUAL RESULTS here will be better than endless posts saying 'its great' or 'it's useless'.
Cheers. :thumbup:

waiting..
I read the reviews on google play, and I flash roms and kernels daily-- so I am holding off till more results are in or I stop this compulsive updating ..

Just installed, will report back in 3 days 7 hours...

I used it while it was still in beta. Uninstalled it - no battery improvements seen. Re-installed it again today, will see how it performs. I use to manually disable what I don't need most of the times.

Google what?

This app has been posted multiple times here on XDA. The general consensus is that it sucks or doesn't do anything.
I've given it a try twice. The last time I uninstalled it because it kept turning wifi on when I was nowhere near a router or hotspot. I'm pretty sure my battery life improved once the app was uninstalled off my phone.

I've been using this app for quite a long time (I think since the first day it came out as beta).
Works as it's supposed to, got the option to disable any sync (OUTSTANDING battery life), simple, minimalistic, doesn't bug.

The only complaint that I had was that before installing, an email from gmail would hit my phone a minute before it showed on my computer. After installing it, even with the use most battery setting for Gmail, there is a delay in notification. I have been using this since it came out as a beta.

Very good program. When it gets used to your preferences, saves a lot of battery.

not necessarily in order to determine what is draining your battery your going to need better battery stats also if you your location , bluetooth that will drain your battery. most importantly some apps will battery hogs like facebook, gtalk if you are using those make sure you get an app called greenify but you will nee to be rooted.

In the past few weeks I've noticed my battery draining noticeably faster than the 1st few weeks I had it. Even running the exact same settings and apps I had before... same ROM versions, same kernel versions, settings, no added apps, etc. I hate to say it's my charging habits prematurely degrading the battery, but that's about the best I can come up with. Still getting the same general stats in BBS, phone stays in deep sleep the majority of time, but instead of only losing .2%/hr or less as when I first purchased, I'm up to around .5-.8%/hr.
