Android Quick App: Battery Indicator

One quirky thing about the Droid’s battery is that it only displays its status in increments of 10. Battery Indicator displays your battery’s percentage in your notification bar, and allows for the pulldown menu to give you a temperature, battery quality and voltage readout. It also lets you know how long your battery’s been running since last charge or how long it’s been since you plugged it in.

Pro version is 99 cents, and allows for conversion from Farenheit to Celsius on battery temperature, startup on boot, and hi-res images.

    It's interesting that so many people want increased precision even though the accuracy is unlikely to match the precision. Is it really important to know that you have 54% charge on your phone vs 50%, especially if the accuracy might be no better than +/- 5?

    PC's have trained us to expect high precision, even when the accuracy is low. Think about the status bar that moves from 0 to 99% in less time than the last 1% takes. Or the download timer that jumps from 2 minutes to less than 1 minute to 5 minutes, etc. as the data rate varies.

    Most automtive gas gauges don't do much better than 10% precision and running out of gas is typically more tramatic than running out of cellphone charge.

      When you study the human condition you learn that there are only a few major personality types, with many minor types and many, many variations (but only about 5 major types).

      Some people do not even care much which version of a battery indicator a phone would have. Some people though, if they see the numbers (example: “62%) their brain needs to stop for a moment and subconsciously convert the numbers into a visual picture that represents 62%. This conversion actually distracts the mind from other thoughts, like a short derailment. Usually, but not always, the person is unaware the derailment even happened but the derailment happens and can be measured.

      Many people have brains that need to have the data input as numbers for the brain to keep running without the derailment. If their brain is shown a picture that almost, somewhat, perhaps represents the battery charge level number, for some there is a minor derailment as their brain stops and converts the vague picture to a range of numbers.

      For some the picture is not what their brain wants to see at all and they will sift though the phones menu until they open the numerical data for the battery percentage.

      These differences between how peoples brains need to collect data is not very controllable by the user (it is not always user friendly). People are born with the idiosyncrasies of their OS and at this time we only have a very limited ability to modify the base code (the base code of the brain) so it is what it is.

      Some people do not care if it is a picture or a number. Some people need to have the visual of a picture and some people need to have the data delivered as a specific number. It is just the human condition.

      My wife sees the picture of the battery indicator and almost doesn’t even care if there is a battery indicator. I am a techie, Electrical Engineer, and sometimes the picture of the battery level looks the same if the battery is at 72% or at 55% and that difference is hugely annoying to me.

      Because I process the numbers extremely well and I thrive on precision, having some numbers in the upper left corner that say 62 is very, very cool (it is very, very necessary for my psyche).

      For the phone to be user friendly to more than a limited personality type, users should have the option of changing the battery indicator from a picture to a number. That way the user gets the input they are most comfortable with. Until the phones have the feature needed, apps will have to suffice.

    Oh this topic… I recommend that the battery is much better than this. Because you get all the information, including temperature, mV of the battery, and correct color coordinated. Nice to visit your site. Wish you post another good topic like this. I will wait to read it.

    Hi have a heck of a time posting here but anyway wanted to share info about the extended battery by seidio it gives me 4 to 5 hours surfing the net I think is good but the con is the media and car dock wont fit battery to big but it does give you a lot more hrs of use

  • droiddrool

    Stick to BatteryLife. Does the same and it's free. Been using it ever since I got my first Droid.

  • Anon

    BatteryTime Lite does the same thing. And you have a widget if you want it. And it's FREE!

    I love that Matt is still stock 2.1 with stock launcher… Makes me feel a slight bit less left out. Also makes me realize how sleek and “simplified” staying stock can look.

      Canadian Motorola Milestones can't be rooted yet, I believe. That, and I'm kinda nervous to root.

  • Static_prone

    The app is pretty cool. helpful.

  • erica

    I discoved this app a few months ago and I'm so happy i did.. It's right on the money and it doesnt take up space on my limited screens.

  • Yagermeister

    A question for anybody who has been using this app and uses Cyanogen…what is the normal temperature you have been seeing with different overclocking speeds? What is ok and what is dangerous?

    • http://twitter.com/Durrock2000 Derek Weber

      Your processor fails at 154, your battery goes into run away heating at 140. This means that it will continue to get hotter by itself even if you pull it, and will quickly release its stored energy, totally toasting your phone. SetCPU has a battery temp failsafe that will take care of you.

      • Yagermeister

        Thank you Derek!

  • pete

    Battery Left Widget has all that plus a widget you can customize, free also!!

  • Nölff, esq.

    Will display temperature in ferinheight?

    • John

      Free version supports *C and *F

    • Mike C

      Actually, it's Farenheit ;)

      • Mark

        actually it can be spelled either way

    • Mike C

      Actually, it's Fahrenheit ;

  • jmc

    If you're are running custom ROMs (CM, UD), for the most part, they include 'Spare Parts' app which provides exactly the same info under 'battery info', no widget though… but you wouldn't have a redundant icon crowding the notification bar consuming power… it'd be perfect if the battery icon % number would do de/increments of 1 instead of 10, just that would let you monitor the battery so much better…

    • http://twitter.com/camsummerson Cameron Summerson

      I'm stock rooted with custom kernel and I downloaded Spare Parts from the market just for this reason, but didn't have that option. Annoying.

  • jawa5636

    I would get this if I could hide the “stock” battery indicator in the status bar. Not a fan of two battery icons up top.

    • jawa5636

      P.S. What is the H in place of 3G?

      • John

        H = HDSPA/HSDPA

        • John

          AKA GSM.. must be from a milestone.

          • kellex

            Yep he's in Canada.

      • jmc

        might have to do with the display reading Toronto…

  • cnpalmer

    I really prefer BatteryTime Pro myself. Nice widget, responsive developer, extra features once the widget is clicked and option to display in the notificatin bar… kind of the best of all worlds. Only thing it does not show is current voltage & temp…

  • John

    Been using the free version for some time. It NEVER shows up in “Battery use”.

    I use this specifically because it IS in the notifications bar where I can see it all the time, not on some widget that I have to scroll to that has an out of place icon (no battery widget has an icon that flows with the Android look IMO)

    The default icon is a HORRIBLE representation of actual life remaining… mine looks like its at 90% but actually is reported as 60% by battery indicator.

    @ Jeremy.. how is a widget going to know how long is left on your charge? .. can it predict the future and know what your usage patterns will be?

    • http://www.facebook.com/jeremy.turnley Jeremy Turnley

      It learns, based on watching your usage patterns over a week or two. It gets pretty close, provided you don't throw it for a loop and browse for 8 hours one day after spending a week of mild use.

      • John

        I looked it up after posting this and saw it tracks usage.. pretty cool. I'll have to check it out.

  • kaufkin

    Meh. Batterylife 1.3.3 gives all that, at no charge. uses widget instead of statusbar, but gives good “at a glance” readout, with more details if you need it. Nice if you don't want to use widget though.

  • http://www.facebook.com/jeremy.turnley Jeremy Turnley

    Why exactly do I want another item eating up space on my taskbar that duplicates one that's already up there?

    I prefer Battery Left Widget; if I am going to waste battery monitoring my battery, I at least want it to tell me how long I have left on my charge rather than feeding me an abstract number rounded up to the nearest 10%.

    • http://twitter.com/camsummerson Cameron Summerson

      I've been using Battery Indicator for a few weeks now and I've liked it thus far, but I've really been looking for something exactly like Battery Left Widget. Thanks!

    • Paul

      Thanks for the suggestion. Once it's “calibrated” does it estimate to 1% accuracy? The ONLY thing I miss about my Blackberry was the ability to know the battery percentage to finer than 10 percentage points.

      • http://www.facebook.com/jeremy.turnley Jeremy Turnley

        It does 1% increments, and can display either the system reported increment or its own estimated one. Tons of options for what it shows and how you want to view it.

        It takes a couple weeks to get fully calibrated, and can get thrown off by you breaking your average usage patterns, but for a free widget, it's a pretty nice and useful tool.

  • rals

    I recommend Battery life much better than that. Since you get all the information including the temperature, mv in the battery, and properly color coordinated.

  • droiddadi

    Any app that pulls battery info eats up your battery life.

    • pyroholtz

      Not if the AndroidOS is reporting the data to the app.

      • joandy

        Android doesn't report it to the app. If I'm not mistaken, Android writes it to a log file and those applications read that log file.
