[Q] Battery life mobile vs stationary

Hi,
I was searching but couldn't find anything with regards to my issue. I've had my Galaxy s I9000M for a bit over a week and have noticed that the battery level, even while doing nothing, will decrease more when I am moving vs when I am stationary. The phone IS rooted, unlocked and I also have applied the OCLF 2.0. I have disabled GPS as well as the 'Use wireless networks' but they seem to have done nothing in regards to prolonging battery life. My guess is that it has something to do either with some kind of location tracking that I have overlooked or the built-in accelerometer. If anyone has any idea what it might be that drains my battery while I am mobile vs stationary, please advise.
Thanks in advance.

I think it got something to do with live wallpaper. I had same problem, before i go to work its 100%. I hardly use it at work cos got a work phone. 8 hours later and its down to 60%. Im on jm8 with digital wall paid live wallpaper.

Varying signal strength could also cause that, as the cell radio will use more power when in weaker signal areas.

I don't think that would apply to my case though, since I am still using the default wallpaper that came with it, but that is definitely something that i will have to keep in mind. Thanks for that.

I have not even considered that, but I suppose that could be a possibility. I'm wondering if there is anything that I could do that could prolong the battery life if what you suggested would actually be the cause.
Anyone else have any possible ideas or suggestions?
Thanks again for the replies.

Especially bad low signal battery life

My house has terrible reception in general (T-Mobile!), but I've never had a phone drain THIS quickly due to searching for signal.
I've set it to 2G only (I only get EDGE at my house anyway, THANKS OBAMA) and it seems to be helping.
Is the Nexus 5 or Kit Kat in general aggressive with searching for 3G/4G signal in anyone else's experience?
Like I said, other phones haven't had this issue.

I have terrible signal too and standby time is horrible. I'll try using faux kernel and report back.

I have same setup as you except my network settings are set to LTE even though there is no lte in my area. Not saying i have great battery life, but it isnt 49% looking for signal.

I have this SAME problem, and the signal on my phone is terrible compared to my last LTE phone.

same problem at work...... I dont know how 1 place can go from lte to 4g to edge all with in a small building with 1 floor. First day while being at school i got 3 hours screentime on lte, today at work i got like 1.5 hours.

27% over 12 hours with one bar seems just fine to me..

Mine reacts different with st att. I get 1 bar of lte in my home when I force lte. If I do auto switch gsm/lte it opts to 3 to 4 bars of hspa, which of course I prefer at home on Wi-Fi.
I've used tmobile for most of my smart phone life and always used tasker to switch to edge when connected to Wi-Fi. Saved a lot of battery. So your experience has been what I normally get.

I have T-mobile as well and my house is in a bad spot. I found that with my note 2 I could use the dialer debug codes to manually set the phone to what ever freq and service I wanted. I found this to greatly help my battery as the modems for T-mo are particularly bad at determining the correct type of service to use and needlessly killing battery.

At least I'm not alone. It's just annoying to have to switch to 2G only when I go home. -.-

Are you guys using wifi while at home? If not then you really should. It generally makes the data modem go into a lower power state if wifi is connected saving battery. Thats how it is on my VZW galaxy nexus.

I do use WiFi at my house.
Sent from my Nexus 5

I have full data bars in my area. If I turn WiFi off and just use data the battery drains significantly faster.

I am new to T-Mobile, I was with Verizon and my house on Verizon barely gets LTE. My galaxy nexus never got LTE but with T-Mobile my Nexus 5 has 3-4 bars of LTE. So I've been using LTE lately and my battery life has been great. I get 5 + hours screen on time with LTE.
Of course Verizon says my area has great 4g service too but anybody who has came to my house either gets 1 bar of LTE or 3g on Verizon. Trying to acquire a signal will of course eat battery though but I will tell you what I am very happy with T-Mobile so far, a lot better then I expected.
I am happy with the battery life and signal strength where I live and travel to.

I noticed this issue today as well... hoping for a solution...

Like I said, manually switching to 2G-only when you're in the affected area removes the problem, but you'll need to switch it back to LTE when you go anywhere with a better connection time. Settings > More > Mobile Networks > Network Mode.

If you're worried about battery life. There's a few things you can do. I found that turning off my "Ok Google" hot word detection increased battery life immensely. Also try turning off Google Now sometimes. I realize that the highlight of this phone more or less was Google Now, but if you don't need it for a certain period of time, turn it off. Doesn't hurt to try.
Try out Faux kernel also. On his test 7 (I think he just put out test 8) I was on track to get 60 hours of standby time. I'll try and dig up the screenshot..hopefully I didn't loose it one of my many wipes..

Do you mean Franco? Faux kernel is only on 002 beta 2, Franco's is on test build 8.

I had this problem and I sent my phone back and got a new one. The new phone doesn't do it at all just got a day and a half with over 4 hours screen time. I think some of the nexus 5's are a bit dodgy.

Yes. Sorry, I had flashed both kernels and decided on Franco for now because it seems he's had the most progress so far. He also received his own device today so he should be able to get even more things done!
Looking forward to both of their kernels!

Major crossroad with Nexus 6

Hey guys, looking for some input here.
Im coming up on the 14 day return policy for the nexus 6, but im really thinking of returning it and going with the note 4.
The only issue i have with the phone is battery life. My phone seems to gulp it down. Now i do have many battery draining features turned off and standby time is excellent. Its when i actually use the phone i get massive drain, whether it be facebooking, web browsing, or playing games, the phone loses a lot of life! My wife used the camera this past weekend for 20 minutes according to the stats and my percentage dropped 25%from 80% to 55% within 1/2 hour!
My brightness is also on adaptive at 35-40%. For the life of me, it just seems i cant stop the battery drain.
I know going to the stock note 4 battery is about the same, but Zerolemon is releasing the note 4 10000 mah battery later this month. I had the same battery on my note 3 and loved it, ive never killed that battery. Yes, itll be a brick, yes but im thinking id prefer battery over function.
I do love the nexus, especially the screen size and the front facing speakers, and i will lose those with the note, but having a dead phone by 6pm makes those features useless. Yes, i could charge the phone halfway through the day, but i was spoiled with the note 3 extended battery.
SO my question is, should i chance the nexus 6 and hope upcoming updates solve the drain, or should i dump it and go with the note 4 and extended battery.
Frank
TL;DR NExus 6 battery dies too quick, return and get note 4 with zero lemon.

I went from the Note 4 to the Nexus 6 and battery life is about the same. I was actually pretty disappointed with the battery life of the Note 4 considering i had a Note 2 where the battery lasted FOREVER! I had originally decided that i would bypass the Nexus 6 and get the Note 4 instead, and at first i loved it but after having to deal with constant lag and dealing with samsung's crappy radios i'm glad i picked up the Nexus 6 (Note 4 is my new alarm clock at home)

It seems that your mind is already made up.. just get the Note 4

Are you using stock ROM or rooted and/or flashed? Sounds unusual for stock. I'd check your network settings and make sure your preferred network type and access point name are correct for your carrier but if standby time is good that probably isn't it anyway. I'd look for an app which gives more detailed battery usage information and go from there.

after going through an S4 and Note 3.. Im glad to be away from samsung. They have amazing hardware specs but drag it down with their crappy touchwiz. It's really unfortunate, the s-pen is pretty great.

im actually fully stock, with just a few apps. I have checked for wake locks and draining apps and down have any. Actually all the apps i had are the same as the note 3 i had. Nothing new.

It seems the biggest drain is during use, not standby!

That is normal on any device. That battery for me is decent. However don't forget that you just got a new device. People always use new devices more initially before they settle into a normal use rhythm. Also I wouldn't worry much about the return date because this device is so hard to get that if you sold it yourself you would probably make money on it. Just give it time.

It's possible that something is wrong with YOUR nexus. I get 5 hours of sot with a stock rooted rom and greenify. Once I decrypt, ROM and kernel I'd expect 6 to 8 easy.

The battery life is obviously important, so it is certainly a dice roll on your part.
For me, I have a Note 2 and waiting for N6 to be available for me. I am so sick of Samsung forced apps and touchwiz. It's not rooted, but I don't feel like I should have to root it in order to get a basic OS without the addons being forced on me by the manufacturer, and then have the warranty voided because of it.

theres no such thing as "typical". we all use our devices differently, and have differing signal quality. you can really ever compare battery stats with another person because of that. only you know how you use your device. so the question is going to get changed.. by how you use your device, and your local signal quality, are you happy with your battery life?

Did you allow google to auto restore settings, apps, data at first boot up? Coming from a different device and OS version could have synced something funky that is causing this. I have noticed this before. Consequentially I never use this feature. I always set every device up fresh (same if switching Roms too in my book). I would try a factory reset at the very least. I have been trying hard to kill my n6 today with no luck, already 12 up time 22% battery left with 4½ hours SOT. Battery stats say I have 3 hours of life left.
Have google now on and going, 2 email clients syncing, g+ syncing, Tapatalk syncing, roughtly 4 active hangouts going, and updated 8+ apps from play store.
Been actively trying to duplicate a power day on this thing. With you experience, something is off with your description and worth experimenting some.

I did do the wireless sync due to some apps needing to recover data.
Maybe I'll try a reset and manually download the apps.

Ive had my phone for a couple weeks now. The first week I had it obviously I was playing around with it a ton and trying different Qi chargers to see how they work. My battery life was unimpressive at 8-10 hours. I was hoping to have at least a full days worth of time based on everything this is supposed to have.
Then I tried a couple things. I turned off the stupid fit application. I ran the battery all the way down until the phone literally turned off. Then I used only wall USB chargers to charge it up.
Now with the same type of usage 3-4 hours of screen time, Im typically getting at least 18-24 hours of battery life. I even managed 30 hours once. Anyway, Im extremely happy with the way this phone is holding up now. Obviously YMMV but I think if you find the right tweaks for the way you use it, it should last longer than you expect.

So Far Today by your stats i will give you mine.
@ 27% Battery Left after flashing Stock a 1.5 days ago rooted/decrypted
Screen is at 4:30:09 @ 42% Usage
Phone Radio 15:30:41 @ 4% usage
Wifi Active 3:24:12 1% usage
Held Awake 2:23:26 0% usage
App Usage 53%
I also have a persistent System (ADSPD) drain that while i don't know how much its draining app sucker puts it at 13.8% vs the next drainer of Android System at 7.3%
Just guessing maybe you are in a poorer signal area than I? Basing that on your phone radio using much more of the percentage?
For what its worth you saw my screen on time. GSAM is predicting 6h 58m total for the day if i run it to 0.

Cell Standby battery drain fix for AT&T

From the Android Central forums:
Settings. . Mobile networks. . mobile data .. enhanced 4g
Since turning off wifi also stops the drain, I might speculate the bug is actually in the voice processing for wider bandwidth and turning off wifi or enhanced 4g shuts down that section of voice processing, which is keeping the radio alive when it should not.

Thanks for that. I'll try this..

Does enhanced 4g mean LTE? What does turning it off do (besides save battery life supposedly)?

Thats HD Voice (AT&T's version of VoLTE). Turning it off disables the Voice over LTE feature.

Does anyone have proof that this is related to cell standby? I am skeptical that this is the smoking gun for battery drain. I have noticed a substantial drain even compared to my old Moto X (2014) and that is saying a lot since that phone's battery wasn't great. I am trying to see where we can make stride to determine the reasons for it. I have different results in my details. Sometimes android system is the culprit.

I turned off Enhanced 4g last night and cell stand by isn't even on my battery usage list today. It was the top one last night before disabling.

How's the overall life now? I just shut it down myself.

Anyone do this and leave WiFi on and still have good battery. Seems to me that no matter what I do WiFi still causes the battery to drain far faster than it should.

I switched off enhanced LTE but if I leave the wifi on I see a battery drain. With wifi off I get a stable battery. My Edge (AT&T) is on Android 5.0.2.
I remember first T-mobile users mentioning battery was ok until 5.0.1 which was later updated to 5.0.2 and the trouble started.

If we could just figure out how to get rid of Google Play services

Im gonna try this too. I keep wifi on. Time to charge up to 100% and see how quick it goes down

So today I decided to keep wifi on and wow. Battery life not as good. Not having horrible drain, but it is most certainly effecting my battery life. So tomorrow I will go all day without wifi and see how it fairs. But I'm thinking that unless I know I'm gonna be at home a lot where I can easily charge, then wifi will remain off indefinitely. Good thing I have 30gb mobile share data

I'm about to try leaving it on all day. Anything that it turns off I don't really need so might as well. And let's be honest, who needs all the power this phone has all the time. I'd say 95% of the time I don't need anywhere near the processing that this beast is capable of.

Possible Battery Fix??

http://bgr.com/2015/05/20/galaxy-s6-battery-life-google-now/

Turning off Google Now is not a battery fix

I was just posting this to share the article.. Personally I use Google now daily so I won't be trying.. but if anyone else wants to test this "theory" give it a shot.. maybe post some results

Or perhaps one could turn it off halfway through the day & extend battery life.. Lol idk ?

BGR are a bunch or turds, they are iCrap homers and are the absolutely the worst. BGR is a great example of what is wrong with journalism and yahoo today, 2-3 paragraph hit jobs without any research. They just scan xda forums or other news sites for the most popular "problem" threads and then write an anti-android article almost instantly.
With that being said and considering the source, no this is not a possible battery fix .
Apologies for going off, but if you couldn't tell, I really hate BGR and yahoo.

5.1.1 is our only hope. I'm crossing my fingers it fixes the memory leak AND cell standby so I can get a wireless charger and have a 100% battery in the morning.

I thought there was a cell standby "fix" already? With VoLTE off and WiFi calling (which is tarded in itself unless you live in an area with bad reception) off, it doesn't even show up on my battery list.

Well that's not a fix its a workaround (I hate VoLTE anyway). I have both off but when I'm in a building with poor to no reception it eats my battery worse than any phone I have ever had. Plus there's no way (I think) the memory leak is causing my battery to drop like it is when it's doing absolutely nothing. I don't have any apps like facebook to cause it either. People on reddit who have taken the 5.1.1 edge leak say the difference in battery life is biblical so we will see if that helps me when we get it.

Hmm. Since I've moved to the Edge (since my first S6 was defective) I'd love to see the improvement. I went from getting 9-10%/hour drain with very little use on my S6 to about 3% with moderate use on the Edge. I'm at 8 hours on battery and 1hr 15 of SOT and I'm still at 75% battery life. For stock, that's pretty good IMO.

Settings/applications/phone/voice over LTE settings (this really deserves a swipe down quick button)

I keep hearing across all of the Galaxy S6 threads how the 5.1.1 update will fix battery and voLTE and Wifi calling issues... I hope it does. My question is when is the predicted date when Tmobile pushes it out to us?
I have had my S6 for a little less than a week, and it's completely stock. Rooting (in any of the multiple ways) seems to have issues with deep sleep, but easy work arounds. I plan on keeping it stock for as long as I can stand, but if Tmobile isn't planning to push the 5.1.1 out in the next 2 months, I will root. Plus, the opportunity would be present to clear out some bloatware
