Ever get frustrated trying to figure out exactly when your battery is going to hit 100% so you can take it off the charger? Well, Google's right there with you, apparently, because in the Android "L" release preview, your phone or tablet will now tell you how long it will take to fully charge.

It appears in both the battery menu of the settings and the lockscreen. You'll also find an estimated time until your battery hits 0% in the battery menu, though you accuracy may vary +/-allthehours, we've found. Hopefully there's some kind of learning algorithm in place here so that eventually the estimate will be useful for more than just posts on blogs about new features in Android. We can dream, right?

You'll also find the new battery saver mode in the settings area, and it's not much different from what you see HTC putting out these days (though not its extreme power saving mode, that's more intense), with Google estimating it'll give you an additional 90 minutes of use time on your phone when enabled.

    That's cool. I've been using Battery Widget Reborn for a few years for that feature.

    I just like having that information available right in my notifications. But, it's really nice that it's right on the lock screen while charging.

    • Shaggyskunk

      Sorry - didn't see your post until now :)

    • https://plus.google.com/108596272537415356460/posts Jason Farrell

      Same, but I'll probably get rid of Battery Widget Reborn when CM updates to Android "L", just so I can get rid of more app I no longer need. How long until empty/charged should've been baked into Android since day 1, imo.

      • Simon Belmont

        Good point. It should have been there at least since ICS. :)

        I'll probably keep using Battery Widget Reborn. Call me weird, but I like being able to quickly see what my battery's temperature is at a glance, too. :D

      • Carlos Miller

        You don't use the "Night Mode" on Battery Widget? That's the one that I find the most useful.

  • remister

    Living vicariously through these screenshot pretending to have L on my Nexus 5, thanks!

    • skitchbeatz

      You're not missing much at this point, honestly.

      • Julio M

        Not the same for people on Gingerbread. They have been missing out very much.

        • Jephri

          Who on earth reads this blog and is still on gingerbread? Seriously?

          • Henry Dorsett Case

            I read this blog even though I don't even own any android device.

            Surprise surprise... Me. 2.3.6 here. Well excuse me for being a super ultra broke and tech-loving person at the same time. *goes cry in a corner*

          • someone755

            I'm 60% sure there's a ROM available for your phone that's a newer version of Android.

          • Đức Thành

            Yes, there are a lot of ROMs for my phone that's a newer version of Android. Except they all come with some sarcrifices, such as battery life, ability to record sound, in-call ringtone, ability to access bluetooth, Wi-Fi and many more, most of which will put my phone in a near-crippled state. It's a hardware-related problem, especially for the M110S model (the Korean version of the Galaxy S) so there's simply no workaround. And I'm not willing to make those sarcrifices just so that I could have an incomplete, unsatisfactory experience of a supposedly newer, but not better version of Android when it's crippled. It sucks, but I'm fine with Gingerbread for now... at least that's what I keep teeling myself. :(

          • someone755

            Well it's not OEM or OEM-based software, so in most cases there are sacrifices to be made. That can be avoided though, with this one simple trick;
            Never buy a Sammy device, especially with a chip that isn't Qualcomm, if you wish to use it after the 18-month support period.
            Yes, there are exceptions, but it generally goes to show you how much Sammy sucks for developers.
            I know what you're going through tho. My old tablet was left off with 2.2. CM7 brings a handful of stability issues (as it the OEM software isn't fucked up enough), and while somebody did manage to port ICS to the thing, it's just too bad hardware-wise.
            My old Desire phone was also left in the dust, with 2.3 only coming as a "developer version," though it did come from HTC themselves. 4.0 did come through CM9, which wasn't all that bad considering I didn't use half the features, but when CM10 was ported it just crashed all around.
            The jump from 2.3 to 4.0 without OEM support is VERY big, going from 4.0 to even 4.4 small in comparison.
            If I were you, I'd sell that GS and buy a used GS2. The thing has official CM10.2 support, and I think it even has official CM11.

          • lovehater

            samsung galaxy pocket ,, 2.3.6,, regular reader of androidpolice...
            but wil directly change to nexus6 or whatever with 5.0

        • skitchbeatz

          He said he had a nexus 5 so it's rather safe to assume he's on at least 4.4.3. Not much difference from that version of Android as far as functionality goes.. and 80% of the Google apps haven't been updated to the new design language

    • senor_heisenberg

      Same here. :(

    • usaff22

      Personally running it here, it's still pretty darn stable for a developer preview. Why don't you flash it?

  • Edgar Martin

    So jealous right now. My power button on my Nexus 5 failed today. So back on my 4. Now to decide if I want to find replacement part or order a different phone or wait.

    • Ramiro Fernandez

      Call Google support, it should be under warranty.

    • Crispin Swickard

      You should totally call Google to get a warranty replacement. I had to when mine mysteriously powered off, and would not come back on again. It was a pretty smooth process. Unless something was done to void your warranty with it..

      • Edgar Martin

        Thanks. Contacted them. Hope removing the back cover didn't void the warranty. That's all the taking apart of it that i did.

        • Crispin Swickard

          Never know know. Hopefully they wont notice either way just in case. Good luck!

  • http://www.anivision.org/ Christopher Bailey (Xcom923)

    The funny thing is people give crap to OEMs that skin android but this version of android is seeing a lot of things borrowed from OEMs. the battery saver from HTC/Samsung and the heads-up display are things I didn't even realize weren't in android by default till IO

    • miri

      I'm pretty sure that what people complain about isn't that OEMs add features but that they go overboard trying to differentiate, bloating the device with tons of unnecessary/poorly implemented features, changing things that were fine originally (and arguably making them worse), removing features, etc.

      • http://www.anivision.org/ Christopher Bailey (Xcom923)

        My issue with that is we have different views on what is necessary and unnecessary and we end up giving OEMs crap about things we think will never be used. but sometimes they are quite helpful

        • DonEmu

          Still very few excuses for Touchwiz's extreme level of bloat which tends to hamper performance as android version increases.

          • ddpacino

            And continues to take up more and more precious space! Sad that their system software out the box leaves you with about half the available storage on a 16GB version.

          • DonEmu

            Which is ridiculous if you think about it. How poorly optimised can things be?

            If it takes nearly 6gig on a 16gig device just for the changes you've made to original android, then you must be doing something extremely wrong.

          • http://www.anivision.org/ Christopher Bailey (Xcom923)

            depends on the changes. Touchwiz is significantly different than AOSP, they tend to add things to the base OS that aren't included in Android by default. ANT+ is one of those things along with other random specifics that they've had to add by hand. Now with L I've noticed that they've included quite a bit of features from both sense and touchwiz.

          • http://www.anivision.org/ Christopher Bailey (Xcom923)

            I'll give you that.

        • blumpkinator

          but they would be more helpful if contributed to AOSP. Then they could improve the Android platform as a whole. Vendor specific features aren't cool. Ideally you would have the same UX across all OEM's.

          • http://www.anivision.org/ Christopher Bailey (Xcom923)

            .....except these are companies that are trying to make money. What you're suggesting would be great in a world were everyone wanted to contribute to a single goal....but that's just now how we live. Companies need money to thrive and if you haven't noticed their features make it into AOSP regardless eventually. the L release is a great example of that.

      • blumpkinator

        also, re-arranging the settings menu. I don't know why Samsung wants to fuck with the settings menu so much.

        • http://www.anivision.org/ Christopher Bailey (Xcom923)

          funny thing about the settings menu is that it is the only one that is customizable. I didn't have issues with it after changing the default. However did anyone else notice that the settings are searchable in L? well guess who started that...

    • Nightfall

      Heads-up display will be the first thing I disable. I don't want things popping in randomly. If I want to see my notifications, I'll pull down the notification shade.

      • Dayfall

        You're missing the point. The "heads up" notifications aresupposed to replace notifications that used to take up your whole screen like calls, alarms, battery warnings, etc.

        • Nightfall

          If I can limit it to those, then fine. But if every notification pops up, then I'm disabling it.

  • vyktorsouza

    I've been charging mine wirelessly and it doesn't show up

    • Joe Micelli

      I'm doing that now and mine shows up. Strange...

      • vyktorsouza

        it shows up now, weird

  • Stanley C.

    I need the wallpapers from L, please?

    • Derp

      I want the greenish wallpaper above

      • David

        It's not from L. My Nexus 5 does not have it. Ask David (I mean, the Ruddock 😃) for it.

  • http://nopenopenope.nope Ryuuie

    For some reason, the time left when charging isn't working on my Nexus 7. :(

  • Stanley C.

    This is a very handful feature! Always wanted this before!

    • tehboogieman

      You can get this ability by installing an app like battery widget pro.

      • Stanley C.

        Really? didnt knew that. Is it accurate?

        • tehboogieman

          It has been for me on my Nexus 4, HTC one, Nexus 7 and Moto X, but it may depend on your device

          • Stanley C.

            Thanks for the tip :-)

  • KERR

    The estimated time is handy - I use WinOff to schedule shutdown of my laptop, now I can fully charge my phone from my laptop and only have the laptop on as long as it needs to be (eg when I go to bed).

  • Shaggyskunk

    Just get Battery Widget Reborn - it'll tell you how long it will take to charge your battery.... Now

  • andrew__des_moines

    Android needs to supply information on what apps are invoking the cellular radio -- that is what kills battery life.

    • DonEmu

      Erm, from my experience what kills battery are apps that keep causing wakelocks. Not specifically apps that invoke cellular radio. Isn't cellular radio always running?

      • andrew__des_moines

        I know that when I turn off Juice Defender Plus, the only feature being used that that restricts internet access to specific apps, my battery life shortens tremendously. Yes your cellular radio is always listening (passive, very little energy usage), but not always transmitting (energy intensive).

        • blumpkinator

          sounds like you have a bunch of apps running in the background that are sending/receiving data. I would recommend adjusting their sync frequency.

          You can also try using greenify or similar to keep them from running in the background. Or use the data usage menu to restrict the app from using background data.

        • DonEmu

          Then isn't that other apps using data and not cellular radio taking battery. Basically some of yours apps keep sending data thus causing a wakelock.

          Cellular radio only transmits upon request. So something is doing the requesting.

          If facebook has created a connection that is forcing you phone not to go into deep sleep, it isn't cellular radio's problem, it's facebook's problem.

          An app like Greenify( if you're rooted) can force apps to stop creating background requests when your screen is off.

  • cmbeid

    I miss the battery percentage/shortcut in Quick Settings.

    • http://twitter.com/yo2boy_ yo2boy

      Google is so weird.

  • Sahil Chaturvedi

    Ah, fuck. The search icon is still inconsistent,

  • http://centralmovers.com.my/ Central Movers

    Good to know its included in new update, I have been using app for this function for long, way to go.

  • andrew borrelli

    I installed L on my Nexus 5 today and the time remaining doesn't show up. I've tried charging wirelessly and direct to wall.

    • MikeOxlong

      Full charge to 100% again and it'll start working. Known bug.

  • Jorell Rutledge

    This reminds me of LG's "stock" battery menu display. Actually a lot of the L stuff reminds me of LG's "stock" Android experience.

    • DonEmu

      A lot of stuff from Sense as well. looks like they're taking the best ideas from the OEMs and integrating them.

  • Bob

    What the heck happened to the Battery Historian? I was all excited for it, but once I got L loaded up....it was nowhere to be found....


    • BruceWillisThrowsACar@You

      It's not a phone app, it's a python script available on github for developers and converts adb batterystats dumps to a wakelock graph. I guess you weren't paying attention. It's not meant for regular ppl unless you know how to use adb and have free time.

    • ddpacino

      This is a feature for developers.

  • Pootis Man

    Yes finally!

  • Steve Freeman

    Am I correct in guessing they still aren't implementing native 1% battery text?

  • Houston Z33

    So ummmmmmm, Where can I find that greenish wallpaper?

  • Fatal1ty_93_RUS

    So yeah... Android L is a mix of AOSP and Sense 6 now

  • http://iron2000.blogspot.com/ iron2000

    Android is adding all those features to tell OEMs to just run stock Android so everyone gets faster updates :P
