    I recently switched back to using my LG Nexus 5 and updated OTA to Lollipop 5.1. I installed the Cyanogenmod 12 rom and have noticed my battery can go from 100% to 0% with light use in about an hour. I tried a factory reset and noticed the same thing happening. I also removed the rom and the issue persisted. The phone also charges up full very quickly. I have no major apps running in the background and the highest battery usage is the screen which uses 7%. Any way to fix this?

    So have you monitor what app or service have been causing that.?

    I don't have any information about what's been causing the drain, when I checked there doesn't seem to be anything out of the ordinary.

    My house has poor signal strength so most of the time i'm disconnected from the network with no signal or i have very low signal strength.

    I'm not sure if that's the main reason but a very weak radio signal causes a lot of battery drain. One of the most battery consuming factors along with display.

    Perhaps you maybe have a wakelock draining your battery to like data sync. I seen some people having Google play service wakelock with lolipop.

    You can also check what kernel's cpu profile you have set up.

    I suggest checking up with an in depth monitor app like betterbatterystats to give you full detail on what's draining your battery.

    To figure out if the bad network signal is causing this drain, switch to airplane mode and see if the same level of battery drain occurs (you can enable WiFi).
    Also, if you share your battery stats screen print (settings/battery, screen print, and then, tap on the graph, and screen print, then tap on the top 2-3 entries, and screen print each of them), that may help figure out the issue.

    Interesting. I thought that aeroplane mode disabled all cellular and wi-fi connections, yet I've just tried it and, yes, it is possible to enable aeroplane mode and switch on wi-fi regardless.

    So what exactly does aeroplane mode do?

    In this day and age, it's just a quick way to save battery and turn off all radios if you're in an area with terrible battery sucking reception. Well, for me anyway it is.

    Airplane mode is just an outdated term, and never affected planes in the first place, similar to having to switch off your phones in hospitals. I mean, I used wifi on a plane the other day lol

    You are right - airplane mode does disable all cellular and Wi-Fi connections, but it doesn't prevent a user from toggling the WiFi radio on after that. If you turn the cellular radio on though, I believe it turns airplane mode off.

    Thank you both. I never use aeroplane mode, to be honest, even on aeroplanes!
    Routinely, I use Power Toggles to switch on/off both wi-fi and cellular data as required.
    As I can still receive telephone calls and messages even when both are off, I assume that 2G(?) is still on regardless.
    Would aeroplane mode disable 2G as well?

    I don't know if this will help, but my battery was draining like there was no tomorrow for a few weeks every time after I received a call.
    Come to find out it was an app called Call Control.
    Call Control was updated to version 2 a few weeks back. I removed it and my N5 is now okay. By the way, I was using Call Control version 1 for years with know issues.

    Airplane mode disables all radios, including cell voice and 2G. You will not get any phone calls or texts with Airplane mode on. The exception is if you then turn WiFi on and you have voip and/or wifi texts set up.

    In the states, when on an airplane they'll tell you to turn on airplane mode on your phone when the plane starts rolling. You can still use WiFi on capable planes. But they want you to keep cell radios off till you're back on the ground. I can't remember about Bluetooth...

    Bluetooth is okay on flights. They don't explicitly tell you either way, but I always use bluetooth ear buds on flights, and I never get any gripe for it.

    Sorry to resurrect this thread, but would turning the phone off completely be acceptable when on an airliner, rather than using aeroplane mode?

    The thing is that when we were in Germany recently I couldn't get a cellular signal, despite my phone being switched to roaming and all the appropriate settings in place. When I called Three upon return to the UK, they informed me that when travelling abroad it is advisable to turn the phone off completely, then when turned on it should pick up cellular signals. On that basis, I'd turn the thing off whilst on the aeroplane.

    Maybe I don't understand the question. You can turn the phone off all you want, but it just means that you can't use it (obviously). If you want to use it on the plane, then airplane mode must be used.

    The off/on thing when traveling helps the cellular profile reset. I've had the issue sometimes where I'm traveling in my car and when I drop LTE coverage the data just doesn't work anymore. If I reset then it works again. So you should be able to just reset your phone when you land and the profile should reset as well.

    Thank for your response.
    What I meant was, is it acceptable to the airlines to (completely) turn off your phone instead of switching to aeroplane mode?
    I understand that leaving on any cellular connections can interfere with their radio communications or other electronic devices. I can only presume that turning off the phone is just as effective and will not interfere with anything.

    Yes. Just turning it off works just fine in the eyes of the airlines.
    As for a cell interfering with other electronic devices . . . that has been shown to not be the case at all.

    I know its been a while but here is a picture of my batterry stats, does it look unusual? And I'll remind you, I'm barely using my phone in this time period.

    Thanks.
    I'd heard reports that turning on aeroplane mode isn't really necessary. Some still demand it, though. We've just returned from Germany flying Lufthansa and they included the announcement.
