Nexus 5 battery drain

[Nav1996]

Android os is draining battery even when phone not in use.. Usage exceeding 60% whereas the next biggest battery drainer is the screen at little as 8%. Anyone know how to fix this?

Welcome to Android Central! The percentages aren't that helpful unless we know how long your battery is lasting, how much screen-on time you're getting per charge, how much time without cell signal you have, etc. If you're doing nothing with your phone, then the OS will likely be a large percentage of use, because it's always going to be doing something in the background, and if nothing else is going on, OS will use a higher percentage of the battery. But the absolute use may not be much.

To give you an idea, 3 hours of total screen-on time is pretty standard for the Nexus 5. Expect battery life to be worse if you often have poor cell signal, since it takes battery to search for weak signal.

Hey, thanks for the reply! My screen time is not even one hour, I charge my phone before sleeping to 100% when I wake up, its like 60%. Phone not even in use, signal strength is strong, wifi and locational services all off. The android os battery usage is always high since the new update regardless of however long i use my phone. I'm only getting around 6 hours of battery while only using my phone for maximum one hour in total.

What are the figures for mobile data sent and received by Android OS?

Try clearing the system cache partition. Bear in mind that it can take upwards of 10 minutes on the N5, so just let it run its course. You won't lose any personal data. http://forums.androidcentral.com/nexus-5-rooting-roms-hacks/352008-guide-nexus-5-recovery.html

I cleared the system cashe partition but that also didn't seem to make much of a difference.

From 100% charge to 47% took 6h but screentime only 1hr 2 mins (usually i would get through almost 2 days from 100% to around 10%)
Then on another day, 100% to 8% took 15h with screentime only 1h 16mins. Screenshots will follow.

Those three are from one day and the following three from another.

Just for comparison, before my batter life was like this all the time. 100% to 40% giving over a day of battery.

The more recent screenshots seem to show more awake time than the older one (that showed better battery life), so you might be using the phone more, or your apps might be keeping the phone awake for some reason. Unfortunately, when OS is the main battery consumer, it can be hard to pinpoint what exactly in the OS is using battery.

Did you go through the Battery Saving Tips guide? Is your Location Reporting off?

 

[Nav96]

Yeah, i've figured that out but really can't tell exactly WHAT the apps are. I've disabled all the google apps i don't use (google+, books etc.) and other apps i don't use. I've had a look through the battery saving guide, i pretty much do all the things anyway. My locational services are off, yes. I just switched to ART mode after reading through some forums that it's shown to give much better battery life, so I'll see how that goes!

Oh, here's something else to try: Turn off any clock alarms that you have set. Don't keep them on the whole day if you actually use them--only turn them on the night before (if you use it as an alarm clock). I've seen behavior before where the alarm clock causes an increase in wakelocks, which might contribute to battery use.

 

[Nav96]

Hmm, that also didn't make any difference.. Android OS keep awake time is so much! I don't know what else to do.. Should I do a factory reset?

 

[B. Diddy]

Factory reset is worth doing, although it's a hassle.

 

[Nav96]

Well it's either that or waiting for a new update because I've literally tried everything

I may have found a solution using wake lock detector from this site: https://docs.google.com/presentatio...F7z06_ysl1kUKME4/edit#slide=id.g25a03f28e_026
Found the app that had the wakelock triggers and have uninstalled it. (Was "smileys for chat" app). Hopefully now my OS keep awake time will be back to normal.
