There are surprisingly few options out there for tracking details about your battery via live wallpaper (and those that are out there are quite ugly), but Battery Core seems to fill the niche quite nicely. The live wallpaper consists of a large, Tron-ish rotating disc, the speed of which varies by your remaining charge. Slow rotation means a low battery, whereas higher velocity means higher capacity. You also get text readouts of the level, charging / not charging status, voltage, and battery temperature. A sliding bar at the bottom indicates your current amount of charge, as well.

The app works on both phones and tablets, and the amount of customization you're able to perform is significant. Sprites and glowing be disabled, basically every color can be adjusted, and you can even scale the circle for your particular display. Some of the features (notably, color changes) do require the $1 paid version of the app in order to be changed. The app ran very smoothly on both devices I tested it on, as well.

Head to the Play Store to grab it now.

    So it spins fast until it sucks the life out of your battery then it spins slower? hmmm I get it.

      :D

      Live wallpapers never gonna be my thing.

      Live wallpapers only run when you're looking at them. If you're going to stare at it the whole time, then yeah.

      But it's a nice little bit of visual candy. Or I guess you could get an OLED phone, put a dark theme on it and make sure your background is blank and black.

      Live wallpapers if there made correct don't eat that much power. I use them all the time in my GNexus hardly anything with better battery life like an S3. 7-8 hours random use threw out the day . I dont just buy anyone I see but from a trusted source.

    ive had it for about a month its pretty cool, reminds me of iron man with the reactor core

    Live wallpapers are like the real need for a computer monitor that has a super thin body. How often do you really look at its side doing your work not looking at the screen? For me, aesthetics are important but not to the extent that it only last 3 sec looking at a background. until my next task. Save money, save battery life.

      its just nice to look at . u dont have to be like those super mega xda power paranoid freaks that will freak out if it uses more than 3% of the battery.

      Maybe some people like showing the iSheep something their phone can't do? Really though, it's great coming across some middle-aged person etc that has an iPhone because their kid told them to get it etc, then show something as simple as a LWP, and suddenly they think it's super neat and begin to loathe their iPhone.

      Everyone has different priorities. Some people like fancy live wallpapers and window animations, and don't care so much about battery life. If you don't want it, don't install it.

    I like his work.. I commented on his post and he responded instantly in the review thread and fixed major problems when it launched..

    Looks like it would part of the One Care mobile AV package.

    I noticed one of your screen shots show a more oval shape than circle. Its probably because my last update I managed to fudge cake one of the settings. I will issue a fix soon...

      I'm using an HTC One on the left - the other screenshot is yours. But yeah, it looks all out of aspect ratio on the One.

      • qkhang

        Wait...did you try using the screen adjuster in the settings? If you did, it probably shifted the app too low and thus it didn't fill the entire screen, right? If not....hmm...

    Awesome. A battery-themed LWP so you watch your battery's charge pass before your eyes. (oO) I have absolutely no use for the novelty that is LWP.

    I like it, lets me ditch Beautiful Battery Disk

    I started using the Digital Flux live wallpaper (paid version) to track my battery level. You can set colors for 0% and 100% and the tiles will gradient through the colors as your battery dies. Great to be able to glance at my lockscreen and quickly (faster than reading) see a big green or red screen (or something in the middle) to tell me how soon I need to charge. Plus it's not hard on the eyes, nor does it chew up too much CPU. Highly recommend.

    I would download this if it had the option to use it as a daydream when charging on my N4 wireless charger.

    It would look very nice with it.
