Has anyone else noticed a direct correlation between average or medium cellular signal from mobile data and the battery being used a lot quicker? I can almost watch my battery drain if I do not have a full five bars of cellular signal

Yes your battery is affected by low signal greatly. The cell signal works harder to maintain a connection causing the battery drain. The lower the signal the harder the phone works to maintain that signal

That makes sense and I appreciate your reply what do you think about when the phone is connected to Wi-Fi? Would a weak cellular signal still affect the battery if the phone is connected on Wi-Fi? I should have been clearer with my question

It depends do you have wifi call enabled? If you do it wouldn't affect it as much. If you don't have it it will affect it quite a bit. The lower your reception the greater the battery drain. I know some people combat it by putting the phone into 3G; 3G usually has a broader signal compared to LTE

I do believe I have Wi-Fi calling enabled I never heard about the 3G option I'll take a look at that

OK, I know there are numerous threads about battery drain etc etc but this is something slightly different,
Look at my sig for what i am running.
Basicly, I can get around two days of battery use out of my HD2 which i am happy with but i have noticed that the past few weeks i have been out at a cirtain night club and noticed when in this night club the battery drain is rediculous, in just 6 hours my batter went from 100% to 7%. Its happed that last few times ive been there, does anyone know why this may be?
In locations with lower signal quality (reception) radio is pumping more juice (battery) into GSM module to achieve better signal quality. My bed room has all 4 walls made out of reinforced concrete and if I take my HD2 with me to bedroom, in the morning I have 10% less battery compared to situation where I left it in living room which was better signal reception (big windows=more signal bars).
Basement location are also known as locations were mobile phones are struggling to achieve decent signal quality.

thats exactly what someone said to me earlier, it makes sence now i've heard it in that aspect.
Thanks for the reply.
I read something about how if the phone is set up for 3g, and there is a solid signal, it takes less juice than if its in gsm mode. But if there is a weak 3g signal, it takes more juice trying to find a better 3g signal. and so in those situations, its better to put it in gsm mode and keep it with a better G or edge signal.
Or something along them lines!! you may want to your phone in gsm mode when you go clubbing, see if it helps

im on it tonight, so i wil give it go.
cheers
+1 yea i agree just change the band settings to gsm this way the phone doesnt keep trying to connect to a poor 3g setting this will eat the battery like u said
Also if you have bluetooth on constantly in a club location you will get the vast majority of other phones in the place trying to make a connection irrespective of whether you are discoverable or not
still a larger than usual drain but changing the setting was cirtainly noticable.
thanks
I think you will have to experience some sort of drain regardless as there is limited signal in a nightclub, you cant really avoid that. I guess since its dark, you can put the birghtness of the screen all the way down, as said earlier, make sure bluetooth is off, erm, disable data connections?
Also, have you given your battery a full discharge, then recharge? You can get a much better battery life once you do that
I've been using USB-tethering over a 3G connection getting anywhere from 0-2 bars in my signal strength indicator at work. The battery level usually remains steady at the same level while I'm tethered.
Now, i'm in Las Vegas and USB-tethering over a 4G connection, with full signal strength. (Does signal strength fluctuate with 4G, or will the signal strength indicator always display "full" in a 4G area?) To my surprise, the battery is actually receiving a net positive charge, as my battery level has steadily increased while I'm USB-tethered.
Also, I notice the phone is cooler to the touch than when I'm USB-tethered over a 3G connection.
Obviously, all of these observations are incidental and anecdotal, but I thought I read previous posts here that 4G drains batteries faster than 3G, but I'm not seeing that being the case.
Is the 3G signal strength a factor for power consumption?
I believe there is a bug with the 3g radio that's causing a higher battery drain. Someone on here was talking about that

I can also say that I too am experiencing the same. 4g doesnt really drain battery that much more (if it is more) than 3g on my Epic. I can go 12 and a half hours with 4g on all day and normal usage...
I find the 4G battery drain consistent moderate drain. You would expect net positive charge while USB tethered as we get 500 ma charging it and no single function can use 500 ma.
4G is still a power hog, and noticeable when not charging, but you are right the amount of 3G cn be pretty bad.
As far as I can tell the 3G seems to draw massive power under poor signal conditions while the 4G doesn't change power, it just slows ,under bad conditions
I have not stringently tested it though, those are just my initial anecdotal impressions.
What I will say is my dormant overnight battery drain has done way up since the last update!
Any one else notice better battery life on lte vs wifi? I'm on 4.4.2 but it has always been like this since I got 4g where I live. On my wifi at home I get about 3 hours screen on time(I even have it set to turn wifi off when screen is off) , vs on 4g I'm getting about 5 to 6 hours screen on time
On lte I get anywhere between 5 to 15Mb down(depending on time of day) and wifi I get about 17Mb down, I know that doesn't matter just saying anyways
Been testing my battery life for weeks and wasn't using wifi when testing lte and vice versa except when the screen was off it would revert to lte, before I got 4g where I am battery life was horrible on 3g. Maybe 2 hours screen on time and my gs4 would get hot
Anyways just seems odd that lte is more efficient than wifi so I don't even use wifi unless Sprint is having network problems.
Thanks for reading my crap lol

Ever since I've gotten reliable LTE at home I never turn on wifi. I only use wifi when I'm in a poor signal building. My battery has never been better since going LTE all the time.
well that baffles me
i thought LTE takes the most juice
i for one always get much longer battery use if im on wifi all day instead of LTE

maybe its based on the signal quality
I get much better battery life on wifi, lte sucks some battery! you're getting 5-6hrs screen time on lte? stock battery? most I saw was a little over 5hrs on mostly wifi
Sent from my S4 using tapatalk
It has to do with your signal strength. A strong LTE signal is much better than a weak Wifi signal. Beyond that, the Wifi DTIM interval can theoretically have an effect on your battery life. If you have a router that allows you to change some advanced settings or are running DD-WRT or Tomato, you can try raising the DTIM interval to maybe 3 or 5m which should improve your Wifi battery life.

Stock battery, guess I got really good 4g signal where I'm at. Sucks cause I'm moving soon tho lol

Ever since they starting attaching the lte unit to the motherboard, the battery life has gotten a lot better. Though signal does effect it, battery is usually better on lte then on wifi.

Does anyone else get low cell reception on 4g and 3g? My 4g cell is around -107dbm with 35asu with 2 bars. Would only having 2 bars drain my battery? My 3g is even worse, although my previous OPO had nearly full 3g signal.
Is this a samsung hardware problem? Saerching around on Google seems like a lot of folks had problems with cell reception on their S6 too
Thanks
Hey. I am just curious. I always get big mobile standy battery drain, also during the night time. It is not affected by enabling or disabling location, bluetooth or wifi.
On battery settings - mobile standy is always bigger than screen drain, I think it is very strange. I am using 4G setting on phone, but anyway if I choose 3G, I got same drain. Please take a look into screenshots. I suppose that there is no fix for it, but I cant believe that all of users have same stats on battery also (4G users).
Honestly, it doesn't look too bad. I would say it is about as good as you can get on 4G unless you use Xposed.
From my experience, Moto voice was the culprit. When disabled I get about 4 hrs sot. Once enabled, cell standby drain jumps and sot drops to around 2 hrs.

Moto Voice is not the culprit or cause... The issue is cellular signal strength, and SD808 SOC does not use battery efficiently unless signal strength is excellent, anytime it drops the battery usage increases exponentially. The OP's Mobile Standby drain looks very normal to me.

No worries... Moto Voice CAN cause battery drain, although it isn't common, it just won't show up as mobile standby, that is purely radio usage.

This is why I primarily use 3G and will only occasionally turn on LTE. 3G signal strength is typically better in my area and it helps prevent the extra battery drain. For the most part, since I don't stream much video on mobile data, 3G speeds are more than sufficient for my day to day tasks like email, forum postings, banking, etc.
I kept Moto voice off for some time when I first got the phone because I worried about battery. I decided to give it a try one day and over the course of a couple of weeks I noted the battery drain was negligible despite always listening so I left it on. Any unusual battery drain during standby/sleep I've experienced since then has been due to a rogue app causing wakelocks but it has never been due to Moto voice that I could determine.

Might want to test with LTE on... In many cases LTE uses less battery than 3G in modern SOC's.

Ou. If you are saying that it looks fine for you, then I believe it. I am living in the place where are a lot of base stations nearby, so I suppose phone is always switching between the cells to find the best signal at that moment. Thanks.
I was just worried that Mobile Standy is always in first place, and then I got only 2 hours of SOT.

If I can get Tasker to do the switch LTE on/off via location I will give it a try. At work I usually get decent enough signal to get data and phone calls on 3G all day but LTE is extremely weak and drops regularly back to 3G so the switching back and forth between bands is murder on the battery and data consistency.
UPDATE: Gave a shot to running LTE on for a few days. Thanks @acejavelin. While my battery life is not really noticeably better, it is not worse either so I can enjoy the greater speed. I just have to manually switch to/from 3G when arriving and leaving work, but I can deal with it.
