I have a huge battery drain, and i think that is because i have low signal (look at the picture).
I tried to recalibrate battery for two times, and use it for 2-3 days, but it's alway the same.
I get maybe 7h with normal use. 50% of the time with 3G/EDGE, 50% with WIFI. screen time 1h, and turned off Auto sync.
Can someone help me? I need my phone whole day, not 7h. :S
EDIT: I'm using stock 4.0.4 with matr1x kernel
Bump?
Can't really help you as cell reception is based on the quality of the carrier. I normally experience -95 dBm and I believe it is a cause for such high drain too.
The only thing I could recommend is try flashing a different radio and see if you get a better signal?
Sent from my Nexus S using XDA
BetterBatteryStats can let you know if it's not the radio. To test if it is the radio, try switching to 2G only.
Well, it was 3G-s fault. I switched to 2G and now there is no battery drain.
BUT, i still don't know why is there no 3G network in my house.
I have SGSII on my shelf, with the same carrier and it has 3G.
There is 3G at your house. It is just weak, much like me. A few too many concrete walls where i'm at.
Cell signals are done through waves which have to penetrate through walls and other solid objects, this vastly weakens the signal. Once you hit the ~-100dB mark your phone will start throwing more power into it's antenna to compensate, much further and it ditches 3G and goes to 2G assuming it has better coverage. Around the 100dB mark it tends to stay with 3G if data is on though which can start chewing through battery. It would be able to play around with the parameters but i don't see this happening anytime soon.
Compare the dB reading on your SGS2 and Nexus S. If it's much worse on the Nexus S, try flashing a different radio.
I have the same problem, i just switch back to 2g when i get back home and at night. for some reason, 2g networks tend to always have stronger reception
Has anyone else experienced any issues like this? Over the past week my Nexus 5 has been going through about 60% battery over night. In the past I would at most use 5-7%. I posted a couple pictures of my battery usage. I live in an area where my signal is always LTE and usually 1-3 bars. I do not have any new apps, location, gps and pretty much all google services SHOULD be off...

If you tap on the graph itself you'll be able to see if the phone was awake frequently or if it was losing signal, etc...
If you're seeing that the phone was awake often, try BetterBatteryStats to see what is keeping your phone awake.
Wakelock Detector is another app to try and pin down the problem.
Also, maybe try wifi overnight instead of LTE to see if that might be the issue.
its your signal quality killing your battery. you have phone idle and cell standby taking most your battery.

I guess, but I dont know why all of a sudden it is doing it. My cell signal has remained the same at home since I got the phone in January. Unless for whatever reason it is dropping out all night...

What is especially strange is it appears you're on WiFi, and yet both the voice and data connection seem to be causing the largest drain here.
Tap the graph so we can get an idea of what the awake times and signal strength was like.
I have a similar gripe and I pinned mine down to stupid photos uploading overnight via wifi and a bunch of other wifi related crap....pretty much network things causing battery drain. also the auto update's killing it for google play stuff.
I found that switching to dalvik and back to ART [which i was on] helped a bit though i supposed there's a process running somewhere in the background that's buggy...here's hoping 4.4.x fixes it
Switch to ART cleared it for me

I also saw the same. Turning off functions, etc. had no effect, but switching form Dalvik to ART did. I'm guessing that the change probably cleared something in the OS that was actually causing the problem. Note that the reported sources of battery usage are almost the same in both images, even though battery usage rate is vastly different.
I've attached two screen shots before and after the runtime switch. The red arrow on the before image is when I made the runtime change.

This is a shot from last night. I went to bed with about 50% battery life and woke up with a dead phone. Looks like cell signal maybe...
I am already using ART, but maybe I should switch back to dalvik and back to art like someone suggested earlier.
I've noticed more battery drain as well as reduced cell signal. My phone is losing connection in areas where I'd previously have 1-2 bars. I was thinking T-Mobile was changing things on their towers, but I'm starting to see other Nexus 5 owners complaining about it as well. Did they update something in the background on our phones?
You REALLY need to get Gsam and take some screens from it after a night. The stock battery usage screen shots say very little of use.
Otherwise we're are all just guessing here.

It's worth a shot, and I, for one, am curious to see if it helps.
FWIW, I just noticed that my battery usage is increasing significantly again. So, I may try the same thing if it persists.
I'd say there is definitely a bug somewhere, possibly interacting with an app or a subset of apps. Are you using Tasker, by any chance?

Good point.
As I noted in my previous post, my phone started chewing battery again yesterday. No evident trigger, battery usage rate just went up abruptly. I recharged the phone and then left it asleep over night. Images below captured this morning.

Obvious culprits are WiFi and radio. Check in gsam (might be too late if you charged) for kernel Wakelocks. Or try wakelock detector app.
You could have a WiFi issue caused by other devices on your network. Would have to search on that for causes and cures. I'm not sure. I only know its been an issue.
And you appear to have no radio signal at all. If you go in to radio screen from main gsam screen, it will tell you your time searching for signal. That can destroy battery life.
It doesn't seem to he an app. Or general held awake time...as you have hardly any.
Putting phone in airplane mode over night would prove its WiFi or radio.

If a night of airplane mode is no better, then its a rogue app. That you'd need to track down. Process of elimination style.
But its probably either WiFi or radio signal. I guess if you have location service on, it could be adding to the trouble.
Turning off WiFi would show if its WiFi....or radio. But with very poor radio signal....I know you're battery will take a beating anyway.

What's puzzling to me is that it was not an issue until a week ago, then converting to ART made it go away temporarily.
My radio signal is poor, but it's always that way at home. I definitely plan to see what airplane mode does. Will report results.
Thanks for your help.

These images are from last night. I went to sleep with about 55 percent and woke up with 31%. The screenies are from betterbatterystats. Maybe you guys see something...
Definitely radio in my case
kj2112, you were right on. :good:
Running in airplane mode removes all serious battery drain on my Nexus 5. If I turn WIFI on, there is only minor battery usage. I've installed OpenSignal and will try monitoring radio reception vs. battery drain.
I'm still puzzled by the sudden onset (could be a problem with my nearest tower, I suppose), and the fact that switching from Dalvik to ART dramatically improved battery life for a few days. That's hard to link to the poor cell signal.
I'm still suspicious that there is a software component, that may or may not be interacting with my cell signal strength.
Follup up / more info
Based on posts on other forums, I tried excluding LTE from my preferred network types, and my battery usage improved dramatically. If I choose 3G, signal strength is 2-3 bars. 2G gives me 4-5 bars. With LTE I get 0-1 bars - mostly 0. On 2G my battery life is the best I've ever seen
My suspicion is that the sudden change I saw was caused by a change in the way the radio software selects network speed options. It appears that if the preferred network type selected is LTE, the phone now will expend maximum effort continually to connect to LTE, even if there is no useful signal available. Before the change, it's likely that a stronger LTE signal was required before the phone would attempt a connection.
I'm not sure if the OS determines where that set point is located or if it's something the carrier can control. If it's the carrier then maybe the Nexus 5 has a radio that isn't as efficient as other phones, and the current algorithm is pegged to the best case phone.
If anyone knows how to adjust the conditions for attempting to connect to LTE or has any ides about who does control it, I'd definitely like to know. For now, I set my phone to 2G or 3G when I'm in a poor LTE reception area (which with T-Mobile is most of the time). That actually works okay for me, but I doubt it's a solution for everyone.
I've noticed that when I leave my phone idle at work, it will drain about 2% an hour even though my signal is stronger (usually around -95 dB). At home, I have a fairly weak LTE signal (usually -100 to -105), but my device will not drain nearly as quickly when idle.
I've been sitting at my desk for the last 3 hours, with maybe 2 or 3 minutes of SoT and it's gone from 90% down to 84%. At home, I'd see about 1-2% drop in the same amount of time.
Are there any engineers out there who would know why this thing would happen? Is it because the phone is switching back and forth between different towers?
This didn't happen with my G3 as the behaviour and battery drain was consistent amongst the two locations.
Do you use wifi when at home and not at work?

I'm an idiot. This is probably it. I'll leave wifi off tonight to make sure.
Though, this now leads me to another question - Is the S6 really that bad when on LTE? As I mentioned in my prior post, my G3 did not drain this much and I didn't use wifi at work with that one either.
Hey guys
I've had this phoen a few weeks, and battery life has been great. Idles well, whether on wifi or 4g....phone idles very well, 2 to 4% per hour.
I recently had my desk moved to an area where cell coverage is BAD. Even on wifi, you can see t he icon go from 3g to 1x, back n forth. signal is weak...but enough to make calls and txt. This is KILLING my battery. I lose 8 to 12% an hour during idling.
Is this normal for phones in dead areas? ANy suggestions?
Thanks

Yes, that sounds normal for the conditions you described. Being in an area where the radio is constantly losing signal and having to reconnect is a very large drain on the battery.
Not much you can do unless you get a signal booster installed.
wishfull thinking i geuss, haha
Previous phones, I would just change the network to just 1x. this usually helped...
Thanks!!!
Not to dig up an old thread....but this is gettign worse...
If I get a network extender (provided I can get it to get GPS), will this prevent the phone from constantly looking? or will the phone still search...
Thanks!
I own an LTE through TMob. I don't do alot on it - I get text, email, use GPS when I run, A little bit on the phone but not alot. My battery life is erratic. Mostly its connected to trying to find a signal when I'm traveling outside coverage areas - at least I think so. When I do that my battery life drops about 10% every 15-20 mins. Anyone have any ideas on how to prevent it from constantly searching for a signal? Current I have to remember to switch it to airplane mode when I'm in the sticks then remember to turn it back on later.
Even on my phone I cut the GSM signal when I am in no coverage zone
Well I guess that's that. Thanks!
