With full signal, even when idle.
It just seems crazy, i am not sure if this was intended to be an always on service or just on demand.
Which firmware are you on, stock or the update? The update seems to have a much more efficient cell radio.
I am on the update but if i keep 4G (and i have full bar) i see about 20% battery drain per hour.
If i am only using 3G it goes down to about 5%.
Wifi only it is about 3%.
Its probably due to how spotty and new 4g is. Its constantly searching for service. It might say you have full bars but you could be going in and out of 4g coverage.
Ah, that is a bummer. I can't compare, don't have 4g in my area yet. Did notice the wimax radio firmware is about 8MB. Hopefully they can update it to be more efficient. Could be the spottiness of the 4G signal, wimax shouldn't be that much different than 802.11 in theory. I suppose it would require higher transmit power

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!
I rebooted my phone for the first time yesterday evening (Camera was force closing after setting Aviate as home launcher), after that overnight phone lost 20% charge, before this reboot - phone was loosing 3 to 5% overnight.
I have not installed any new apps, also checked GSam battery monitor and didn't see any app sucking more juice. I was checking different things and noticed network signal strength is much better than normal (95-97 dbm, usually it used to be 103dbm at the same place), checked network mode and it is set as Global instead of LTE/CDMA, I remember it was LTE/CDMA before reboot and my signal was 103dbm.
During the last couple of hours also I am loosing 3 times more battery than normal, so looks like Global network mode is giving better signal compared to LTE/CDMA mode but using more battery. I am all for better signal strength but not at the expense of battery life.
Does any of you noticed similar issue? Does network mode selection has any impact on signal strength & battery life?
Mine is sort of opposite. It had defaulted to global and was at 91% battery being mostly idle for 16 hours. Just switched to CDMA/LTE/EVDO and signal went from >-100 to -97 dBm but could be normal fluctuation range. Will see how it affects battery life but so far it's still at 91% battery having switched over more than an hour ago.
I just checked mine , it showed -81 dBm for LTE. Switched to Global and it went to -75 dBm then right back to -81 dBm.
OK so I'm not sure about dpm, as far as if it's better to have a higher or lower number? But, I did however switch from Global to LTE/CDMA and I'm definitely getting the 4GLTE symbol way more than I was on Global! I was in 3g quiet a bit on Global. And Verizon has excellent reception in my area. I noticed yesterday that my wife was in lte on her iPhone while I was in 3g and we were sitting next to each other. It's much better now.

dBm... lower is better
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

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.

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.
I'm considering switching to ATT which requires a phone switch too. Anyway, looking to pick up as used S8 and have no ATT signal inside my house. Maybe 1 bar in some areas. In the past I would have terrible battery drain to the point of an hour of SOT with a Sony Z5C. Most battery went to cell signal. ATT stopped giving out femtocells saying Wifi calling is good enough. But... with a weak to nonexistent LTE signal, even if on great Wifi, am I going to be using up my battery searching for the LTE signal or is the S8 smart enough to no waste the battery on that? Anyone's impressions of having great wifi and no LTE on an S8 series, while using Wifi calling?
