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.
Hi,
I'm experiencing quite big idle battery drain, but not always. Sometimes by battery lasts for 3-4 days with minimal usage, but some days it goes down by up to 4% per hour with no usage. I'm sure it's not a rogue app keeping my phone awake and I've done the Google Play Services "fix" in App Ops. I'm running stable crDroid KitKat with stock kernel, and a lot of people don't seem to be having issues.
I've attached some screenshots from Wakelock Detector. It looks to me there is an insane number of wakeups for some reason. Has anyone had anything like this and managed to fix it?
Thanks.
Connectivity service is probably your culprit. It's a very bad battery draining wakelock that happens when you lose network signal and It keeps your phone awake until it finds another signal. Your best option would be to try out a different modem

Don't forget to hit thanks!

Thanks for the reply.
I think you're right. I was looking at the stats today and I saw a lot of wake-ups by 'RILJ' under phone, which also suggest my issue might be modem-related. I've attached a screenshot for reference.
On a side note, it seems a bit weird how WLD shows a lot of wake-ups by SwiftKey with 'AudioMix'. I've never fully trusted that these apps show accurate stats, especially when it comes to system processes.
But anyway, I'll give a newer modem a try when I have the time and report back.
Thanks again :good:
Phone radio is killing my battery on a S6 & Wifi signal is very poor - please help?
Hi folks,
I'm new to these forums and having read through more posts than I remember I think I need some help - apologies in advance for the length of this post!
I bought a S6 approx 4 weeks ago, having had the S4 which served me well. I immediately noticed two issues
1/. Battery drain
2/. Poor Wifi signal
1/. My battery drain is currently unacceptable, I charge to 100% and unplug overnight so screen is off - I wake up 7hours or so later to find it has drained overnight to 75% or even less. I have power save mode on ALL the time, I have disabled all the non essential and probably some essential apps such google player etc. I have location, NFC, Bluetooth, Sync, Always allow wifi scanning, none of my apps are set to sync automatically etc switched off (having read all this good info on these forums). I installed GSAM and never saw any major issues although the screen would be showing close to 40% (I have black background and only on Amoled Photo display rather than the Adaptive display which is so much better!) I then read on a post today the GSAM Wifi profile had to be edited to 767 to show an accurate usage - I did that this morning and lo and behold I have a Phone Radio zapping 43% battery. Can someone please tell me how to switch that damn thing off or how it can be managed? I notice the battery issue is alot worse on wifi than using mobile data. I have attempted a cache reset post 5.1.1 update. Any other ideas on saving battery life would be very much appreciated.
2/. Wifi signal - I have a Virgin Media Superhub router on a 50meg connection. My S4 had no issues throughout the house picking up a very good signal and wifi speed was excellent. All other devices such as laptop and IPAD have no issues getting a good signal on both 2.4G and 5G On my S6 unless im in the same room as the router it is extremely poor and I'm guessing has also something to do with my battery draining so the two may go hand in hand? Again having read many posts on these forums I have changed my wifi settings DNS 1 & 2 to 8.8.4.4 - I haven't seen this make much of a difference though. I used the DNS SET app I read somewhere would also help but unfortunately the poor signal and slow speed continued.My battery drain is worse with Wifi so I try to use my data plan but im using that up very quickly and would love to use wifi! Does anyone know anything else I can have a go at?
I am loathed to try the factory reset option if there are other things I can attempt first to save me setting up the phone and my go launcher app etc. I have attempted to attach some GSAM screen shots but cant find an attach link anywhere?? can someone advise how to do this? more than happy to provide any other info. Any help would be very much appreciated - thanks in advance.
I have the low wifi signal problem too. My friend has an S6 and has also poor wifi signal at the same spot. Others phones like z3 compact or moto g2 have more signal than s6 at the same spot.
It's annoying.
I recently got an OPO. I noticed that my battery was draining quickly so I checked my battery usage. It turned out that cell standby was the culprit. I also noticed this happened when I go to school, where I almost never get signal. I have searched everywhere and cannot find a clear solution. I need to know how to fix it.
I am running Cyanogen OS 13.1.
Carrier: Lycamobile

Switch to airplane mode if you're in a place with no signal.
go to custom rom..........cm 13.1 also has problem with mobile data.

Hi!
My Huawei P20 is draining very fast when connected to my wireless network. I get like 20-30% drain overnight, which is huge. When using mobile data I lose like 4-5% (when I first got the phone I was having this percents on wifi also, after some time the drain started to happen) which I think it's pretty good.
Has anyone else encountered this issue?
Same problem here. I am on firmware 9.1. 0.325

I still didn't find a fix for this. There are some times when the phone works well, and others when the battery drain fast. If the phone runs out of battery and closes, when I charge it, the next couple of days it drains fast on wifi, after this it works well again.
It is a software problem for sure, but don't know what is causing this. My firmware is 9.1.0.371
I think the optimiser switches off WiFi and there is a reason for that
