My battery life was fcuked: losing 40%-%50 overnight while it was inactive sitting on the nightstand.
(Factory reset did not help at all!)

Now after futzing with the WIFI setting, last night I lost only 5% total in 8 hours sleep time.
Furthermore battery read 18% remaining at 10:30 PM and still read 18% at 4:17 AM.
Now this is more like what my iPhone 6 gets while sleeping.

What seems to have fixed by battery woes.
I changed the (Advanced) WIFI frequency setting from Automatic to 5Ghz (which would not work at all) and then to 2.4 Ghz only.

As of today I have 87% remaining after 3 hours of casual use (after charging to 100%.) Previously (for the past week since installing Lollipop) I was losing about 25% per hour during casual usage - ridiculously bad battery life.

Hopefully this will work for someone other than myself. I had just listed this thing on Craigslist because I cannot use a phone with 4 hour battery life.

Good luck.

Just set it to the same WiFi setting, will get back with screens.

Thanks though, I have brought this phone recently and thought it was only me getting bad battery life :\ I've had to charge this phone more than I did my nexus 4. I brought it off someone after they had used it for 9 months.

try setting it back to auto and see what happens. IE, try to replicate the issue and the fix.

For me, I went back to KK 4.4.4 factory image and took OTA seems to fix the wifi idle to just same as OP overnight (~5%). But after some use, it can drain quick but not as quick as I was on custom ROM (all kinds I tried).

This can happen when the phone is being moderately used before a longer idle period. The battery percentage will actually go up to compensate for the earlier usage estimation, giving the illusion of zero drop over night. It becomes clear after seeing the graph and the line going up only to drop down to the pre-idle level.

Kind of annoying since I'd like to see how much was actually lost over night. Just something that happens with the estimation process that is our battery level.

I recently switched from 2.4Ghz only back to Auto mode as it seems the WiFi speed drop issues are no longer present on my particular home network. No battery drain or issues yet but I will keep a close eye on it. Thanks for sharing.

.

I think your statement is true, as I noticed that with OTA updates, my idle over night is very low. However, upon using the phone the battery immediately starting to report drastic drop in percentage number. I mean this is cruel as in it gives us a false sense of battery consumption over all lol.

I'm going to give this a try. I've been using an app to turn wifi off when asleep but am still getting higher drain on wifi with the screen on than should be. Will report back after a day or two.

Personally I don't think they fixed the wifi miscellaneous drain and just hid it in the usage stats. My battery life has never been the same since the final dev preview. Luckily I'm always near a charger.

Did you guys read the entire OP?
I have had an overall drastic improvement in battery life - not merely during idle time ;)

Right, I did read the OP and actually did make the same adjustments. However, I didn't see any improvements on my KK 4.4.4 upgraded to L via OTA in terms of idling overnight. My idle stats are very good even prior to the adjustment mentioned and same post adjustments. However, the freaking issue is when I started using the phone.

I think it is varies wildly for each user and their phone.

" the freaking issue is when I started using the phone.”

Indeed, this is another issue with this phone. Battery is too freaking small.

At this point i am back on my iPhone 6. iOS is a bit rigid for my taste, but the thing is fast, great screen, and runs two days on a charge, call quality is superior, louder speaker, etc!
Battery life is critical, yo.

I feel ya, I tried a 5s and iOS 7 out for about 6 months because it looked nice. Had great battery life until I had to jailbreak it to get it to do what I wanted (which is stock/non root stuff on android) and apps from cydia rocked my battery ;-( then it was like why am I having to tweak the crap out of this phone to do simple things I want that shouldn't be a big deal in the first place? Finally just decided to come back to my N5 in the end.

This. I hate how much my battery drains when my screen is on. I'm convinced some of it is Lollipop though. I got a feeling it is also related to the memory leaks.

Agreed about ios, but it is getting better. The notificatiins just got a lit better....little things are slowly improving.
Something that is GREAT on iOS now: voice to text is screaming fast now, and extremely accurate. I rarely type emails and texts now. No kidding!

I went back to 4.4.4 last night - as while the idle drain was fixed with these settings, the overall battery life while using the phone under LL is still relatively miserable.
4.4.4 seems a bit better...
Now I see that 5.0.1 is apparently being released in the next day or two...we shall see. So far the release notes say nothing about a battery fix.

Does no one else realise that a major OS update needs to "bed in" for a good few days? The battery life performance is a lot better on LP. I've an HTC desire 610 though and it goes days between charges. It's a 420 battery but 1/4 hd screen. You take your choice of features and find your phone/s

    I've never had great battery life with the N5. Definitely never had it last a full day with moderate usage
