I am no the At&t network, I have installed a rom that lets you choose your singnal type. what is the best signal to use for low power consumption but isnt too slow?

For less power consumption, choose one that avoids LTE, especially if you don't have LTE signal in your area. I use GSM/WCDMA. I get HSPA+ speeds all day long.
If you REALLY want to save power, choose the "2G Only" option... and be prepared to switch it back when you realize how slow it is!
Is there a way to disable cell standby when out of service or at least make it not cheeck so often, my house has spots without signal so standby is ussaly 10% of battery usage.

standby is important and cannot be disabled
you can disable your data connection when your in a poor zone manually, just get a widget like power toggles and its a one click button on your homescreen to toggle data on/off

Yes, turn on airplane mode which disables the cell standby

Hi there,
I'm currently trying to maximize my battery life and I ran into something weird.
I've currently have tasker on disabling and enabling data (screen on/off), greenifying, kt747 with under volt and under clock etc.
Under normal usage I can probably get 2-2.5 hours of screen time and a total of 6 hours of usage time at work. I was told this time wasn't great and I couldnt see how I can fix this problem.
Then at home I had my wifi enabled and left my phone sitting idle and noticed it drained a lot slower. I ended up with over 1.5 days of usage and 2-3 hours of on screen time.
The odd thing is...my screen was off most of the time, meaning data was both off. Wifi was on at home, also to note the signal strength was significantly weaker at home and its LTE. Thats why I'm so piuzzled why at home I can get much better battery life
To recap:
At work: (6 hours)
HSPA (not LTE)
Great signal (full bars or over 22 on the real signal app)
screen off during idle data is off
no wifi on
At home (36 hours)
LTE/HSPA (swapping back and forth trying to get a good signal)
Terrible signal 1-2 bars (0-5 on the real signal app)
Screen off and data off
wifi is left on the entire time
My question is what is causing this difference? What am I missing here. How can I get the longer battery life without being on wifi

Ever looked in BBS (betterbatterystats) to see what was using your battery?
Also, battery life depends on a lot of factors: kernel settings, widgets, refreshes, app running in background, etc.
Running on Wifi is much easier for our device than running on data, which can explain a bit of the difference but not 5x the battery life. UC/UV can be good like it can be bad, if it takes too much time to load something = more screen time = more battery drain.
Btw, you didn't mentioned what ROM/kernel you are running?

hey bwolf56... oh yea definitely look at my BBS, thats another question i have to resolve since it stays awake quite a bit more than I would like........but I'll go into the BBS portion a bit later.........
To address your questions.....and whats puzzling is that in both the at home and at work scenarios
- bbs are the same
- kernel settings remain the same
- widgets have been the same, refresh have been the same
- no syncs

I agree that running on wifi is easier....but in both those scenario data is off. At home its wifi, and at work its no data. Shouldn't no data take less power than wifi?
Additionally at home its, LTE, low signal, etc. Which all supposedly drain batteries.

As for BBS.........deep sleep for the processor accounts for majority of the processor state.
Though the "awake" bar on the battery status shows it gets woken up quite a bit.

There is an additional finding.......... I did a brief test at home without the wifi on.........with screen off.......about 4 hours the battery drain 8%....I want to say its worse without the wifi, but not as bad as I would have had at work with the screen off.......I'm still inconclusive on this point.....
What would make this easier to test is if I had wifi at work. Then I can narrow it down to wifi only......but i dont.
I'm try to investigate as much and I'm stuck.

Your signal strength doesn't matter so much on newer devices (especially on Wifi). Being singal-less will drain your battery but as long as you have signal, it shouldn't affect it (too much).

A 30min to 1hr screen time difference it basically what data will do. If you compare screen on time, it means your data is on. So there's something else that is hard on your battery while your screen is off at work.

Most of those will use a lot of battery if GPS/location access is on. Data doesn't help of course.

Ok this last part makes it seem like it's something with your area/carrier. You mentioned that you get LTE at home but only H+ at work, which means that either your work building is in a bad reception area (or simply hard on the signal), or your carriers' towers need update.
Are you able to do some testing outside your building? In the same general area (couple kms near it).
Have you tried to disable LTE while you are at work? You might be getting battery drain while looking for LTE. I could be wrong about this but it would seem logical.

Ive been reading in a lot of threads that LTE supposedly drains more than H+ and other non 4G signals. Either case, it doesnt apply to me.
I also wasnt aware that signal-less was what caused the battery drain. I do know my LTE at home fluctuates from really bad signal and the odd signal-less.
As for Wifi, I wasn't comparing the signal strength of wifi. I was simply compairing that during the off screen state
At home uses wifi
At work uses nothing.
One would think the nothing drains less than wifi?

During screen on time, the draining speed is understandable to see H+ draining faster than wifi.

It isn't actually ''nothing''. It still has to communicate with the towers, if it only sends H+, it might be because it's having trouble (or that area doesn't have LTE just yet). That being said, your device might be perma looking for LTE and can't get it = causing battery drain.

Assuming you are on an AT&T device running stock TW, you can disable LTE only. However it is only good until you reboot or switch in and out of airplane mode (it reverts to looking for LTE). Create a new APN with name and APN name only filled out and save. Select it. Wait 20 seconds and go into dialer and dial *#*#4636#*#* and select "Device information". It should say "WCDMA preferred" under preferred network type. You need to change it to GSM/CDMA auto (PRL). Exit and go back to your APN and select the one for LTE. After a couple seconds you will have data back and it can switch automatically between 2G and 3G.

So yesterday i left it idle with 8 hours and it drained .6%/hour, i lost 5% in 8 hours
I woke up turned off wifi and in 3 hours I lost 2% which is about .7%/hour.
I'll give it a try at work.....
the only change i made was wifi off.
The location is still on
I have a new radio firmware i want to try as well, but that will have to wait.
Attached are my BBS logs, seems like theres lots of wakeups
EDIT: i have battery spy, during idle it drains at .5%/hour, but when i wake it up then make it go to sleep, it hovers at 8% then 3 % for a while. Why is that? How can I make it drop to .5% immediately?
I've noticed lately my battery life has plummeted. When I get to work, I turn off wifi, and even after very light use throughout the day, 9-10 hours later it will be giving me the low battery warning. I checked the Battery screen, and noticed the Wifi bar is solid blue the whole day as seen in the attached picture. If I am reading this screen correctly, wouldn't that be an indication that wifi is actually on all day? As you can also see in the screenshot, the wifi logo is not on at the top, showing I do in fact have it turned off. Do I have a problem? Does anyone else know about this issue and have a fix for it, if it is in fact a "issue"?
Go in to your WiFi settings, hit your menu button and hit advanced. Uncheck "always allow scanning"

Thanks, doing that this morning and will check the battery screen in a couple hours.
OK, that seems to have taken care of the wifi appearing to be on in the battery stats. I will wait until later today to determine if that was the cause of my battery draining quicker. I know there were a few new apps I installed around the same time, and I may have to start digging through those too.

Are u in an area that has low lte strength. If its switching between LTE and hspa+ that is tough on battery. Or location settings, or random apps running in the background. Grab BBS and see what is eating up the battery, wake locks apps etc. Their is am Xposed module that dispatches of wake locks if that is your issue. But I'm guessing its one of your apps or signal.

Go in to your mobile network settings and change the network mode to wcdma/GSM instead of lte/wcdma/GSM if you're always switching between lte and 4g. Try that at least.

if possible grab WiFi at work, and use only that and I bet your battery significantly improves. then when u leave, hop back on normal data and see if that helps
Well, I've tried the setting the mode to not include lte, still getting pretty quick battery drain. There is no usable wifi here due to the level of security my facility enforces. Anything I can have BBS export to have you fine folks take a gander at and see if you find anything relevant?

Well, so iv tried several things to improve my battery life on our sg4mini. My phone is rooted with custom kernel installed, running official rom. U can see my phone informations in screenshot attached. Im using greenify - the extended version with experimental functions. I hava also removed most of stock - non useful applications via uninstaller app (eg. samsung apps and other). Almost all my current apps r greenified, i left only Viber active cos im communicating through that app. I attached screens with my battery life from a normal-usage-day like: some internet browsing, 9gag and other social network apps. So the battery lasted 15 hours, with like 4h with screen on, so its not that bad i guess(i mean the screen time). Anyways, i got my gps, nfc, smart stay, s beam and other options turned off all the time. i only got data transfer turned on all day long, which means im mostly connected to LTE network. And that, i guess is the reason of such low battery capacity. I got the Vikinger kernel installed cos as i saw several posts about some error in stock samsung kernel i decided to flash some, which may help. SS from Wakelock detector attached aswell. I also installed CrossBreeder cos i found some good opinion about this and improovements it gives.But well, i guess iv done all i could to improve battery life. screen brightness is automatic at -5 status+ energy saving mode is turned on all the time. So i guess the only thing that drains battery that much is this LTE usage. the point is: i dont wanna turn the data transfer off in a daytime cos i constantly use viber to communicate. I was trying to find some app that switches LTE to gsm network but i havent found any proper. I guess that could be the solution because i could still respond to Viber messages with data transfer on, and the phone wouldnt eat so much battery on connecting to networks like LTE. Do you think that could help? if yes, is there any good application - widged preferable- so i can easly and fast switch LTE to GSM when i need to browse internet fast etc? Or maybe is there any better kernel which repairs battery problem.
As i said i dont wanna disable data transfer cos i need it, well, what for did i get such good phone if i cant use it in simple way w/o worrying about the battery?
Cheers
So as far i have checked several connection switching applications but couldnt find one that actually switches lte to gsm by pressing one button. All i had found were just shortcuts to the network options so to change my connection i had to do several actions. What im looking for is an app with trigger like button which will automatically switch between gsm and lte - switcher like the stock data transfer button for example. For now i installed Switch Network Type 3G/2G (screens attached) which gives me an extra button in slide bar but only leads me to options.

i didn't read all of your text because it's just too long for me. but if you want an advice for battery improvement, try setting cpu max frequency to 1000 or lower (at 1000 it's still not really laggy at messaging etc. but battery should improve) :fingers-crossed:
Well the post seems long cos iv really tried maaany things to improve batt life. I will give it a try with CPU settings tho. But still im seeking the real drainage problem so my question is: does network connection have such an influence on battery life? any advices,programs etc appreciated
If with LTE connection you reach at least 3 hours, everything is all right. Normally i can do at most 3 and half hours of screen with LTE.
Hi guys,
Apologize me for my bad english.
I've got a problem about signal bars that are not matching what's displayed under "Options/Info/Info/Network".
If I activate WCDMA network, in a lot of locations the M8 displays me only 1 or no signal bars on screen, but if I check under the Android infos, I can see the signal is much higher (like -80/-75 dBm). In one situation, i got -65 dBm signal strength but no bars were displayed. It could be minor problem to your eyes, but it's very annoying for me. Can it be caused by the fact i've a Vodafone sim but my phone is branded H3G? Is it only a my problem? Because i'n think about a replacemt...
Also another question: have you noticed an increased battery draining from Android OS after the update to 4.4.4?
In general, like now, Android Operating System is drainig 16% battery (sometimes it reaches 19%), Andorid System 12% and user interface 4%. Before the update i am sure these percents were much lower, like 13%, 9%, 3%... Maybe it's only an overhall 10% or less, but it's a 30 minutes or more of Internet browsing or calling time...
And before you ask, Yes i've already done a factory reset and wiped cache. Nothing changed
What di you think?
No one?

i don't know about the signal problem, but your battery issues should be solved by going to settings > accounts & sync > google > location (turn off or pick a less battery hungry setting; off is best for battery.) Also: google > ads and opt out of interest based.

Thank you for the help I will read it for sure.
However, i will post the screenshots here too, so maybe someone can compare their stats with mine.
The screens are only about the last 40% of my battery
