Nexus 5 standby time increases sharply after installing Android M

Android M is going to have a few interesting and exciting features. One of them is called Doze and is activated when your Android handset is inactive for a period of time. With Doze, the phone goes into a deeper sleep than it currently does and and a result, standby times are more than doubled. Once Doze is disabled (which happens when you pick up the phone), syncs and open tasks which were halted are carried out by the model.

Another feature of Android M is App Standby. With this feature, once your phone is unplugged, apps deemed to be inactive are prohibited from receiving network support and any syncs and open jobs are suspended. Once you plug in your phone, the idle apps will regain network connectivity. Android M will most likely offer those who need specific apps to run at all times, the ability to disable the feature on certain apps.

To see how Doze and App Standby might work in real life, a Nexus 5 was loaded with the Android M Developer Preview and measured against the same model loaded with Android 5.1.1. The result? After 8 hours in standby, the Nexus 5 with Android 5.1.1 consumed 4% of its battery life as opposed to 1.5% with the Nexus 5 running Android M. After 24 hours, the Lollipopped version of the stock Android phone had burned through 12% of its battery life while on standby. The Android M powered handset had used just 4.5% of its juice during the same amount of time. After 48 hours, the Nexus 5 with Android 5.1.1 inside had devoured 24% of its battery power compared to the 9% used on the Android M powered version of the phone.

The Nexus 5 with Android 5.1.1 installed was projected to provide 200 hours of standby time. With Android M, the standby time was projected to jump to 533 hours. That means that Android M provided the phone with 2.7 times the standby time available with Android 5.1.1. This is an exciting bit of technology that Android users should be greatly looking forward to.

Thanks for the tip!

I'll take it. A lot of focus is placed on screen-on time which is definitely important but it helps to hit the problem from all sides.

Stand by is pretty great on M But it still could be better IMO My wish is for a option in dev setting to enable manual power saving tools E.g. A manual switch for Doze mode, since right now it only goes in Doze after being left still for 10+ minutes And an option to choose which apps are placed in App Standby mode, since there's some apps I don't use much, but still want notifications from (haven't had any issues yet though)

We already have that. It's called Battery Saver mode on android

But that's far more intense It turns off animations and some CPUs, caps CPU and GPU clocks, dims the display, turns the nav bar orange, ... In comparison, Doze just ignores all wakelocks and prevents syncing (except high priority GCN pushes)

Who needs standby? I'm not placing my phone on shelf. I'll be using it everyday. So please focus on how to improve screen ON time. How to lower battery drain while on mobile data.

you sound like you dont sleep, no job and no social life if your phone is on more times than off.

LOL! my phone loses only 1% overnight. Xperia Z3 here. Most phones already do better losing only 1-3% overnight.

Yeah you only need a capable charger.;-)

Well your phone has a more battery friendly chipset and a bigger battery (3000mah as opposed to the 2300 of the nexus 5)

That's a pretty stupid comment to make. As a System and Network Admin, I use my phone for work all the time. Between work and personal related stuff, I easily average about 9-10 hours of screen on time a day.

So you're on your phone 24/7? I'd use mine for about 5 hours SOT max (if I have my battery pack, since my Nexus 5 tops out at around 4 hours SOT) The other 10 hours my phone would be idling Doze would mean its not using as much battery while idling But right now Doze doesn't kick until about about 10 mins Which means it doesn't kick in much during the day, unless I rest it on my desk during classes That's why a manual Doze button would be awesome Basically like Sony's Stamina Mode

I'm not saying I need 24x7 battery life. Most flagship phones these days have good standby. My Z3 lasts 2 days easily but while browsing on mobile data, WiFi, it hardly lasts a day and also heats a lot. So if google manages to optimize the way phone sips battery under heavy loads, it would make a huge impact.

Well your Z3 already has Stamina Mode, which is similar to Doze I don't there's much Google can do for heavy load situations (the same for Apple or Microsoft) Heavy load situations generally can only be improved by more efficient hardware There are a couple software things I know of which will likely help for heavy load situations Vulkan (allows "full use" of CPU and GPU for graphics, mainly for gaming) HSA (allows CPU and GPU to work together more easily) Unfortunately none of those are in Android yet since they are not completely finished yet Probably have to wait until Android N for those, or even maybe Android O for HSA

turn autosync off and only sync when you need it.

I have M on my nexus 5 since day one and the battery definitely got better. It is better than CM12 with elementalX kernel. And this is just the first beta.

Calls and text still come through, correct?

I imagine that core features of a phone like calls and texts would remain enabled unless all network connectivity is disabled by the actual user.

Yep those still go through And alarms still go off Also high priority GCM notifications also go through, not sure which apps use this Hopefully apps to try abuse it and set all their GCM notifications as high priority

hope it's not as hopeless as lollipop

Please enlighten me as to what the major issues are with Android Lollipop 5.1.1? No really, I would like to know, because from what I've been told, most of the issues with the last couple releases have been resolved.

Was running 5.1.1 on my Nexus 5 Memory leak was basically fixed Battery life was similar to KitKat Only issue I had was with the bug where sometimes face unlock would crashed and then stop me from using the camera. Pretty annoying, but once I disable face unlock the problem was fixed

10. Scott93274

Posts: 6032; Member since: Aug 06, 2013

Cool, thanks, I used Face unlock for a week maybe. Not all that great in the dark or when I feel lazy and don't shave for a while.

Do not pay attention to him, he probably haven't even used it.

15. Mxyzptlk unregistered

You haveno proof tthat he did or didn't. Baseless comment.

18. Scott93274

Posts: 6032; Member since: Aug 06, 2013

Well, he has yet to back up his statement so as far as I'm concerned Carlemillward is spot on.

I could say the same with every comment you make.
