DetailedBattery Usage

Developer Hamza Sood, well-known for his innate ability to uncover hidden items in iOS, has discovered another hidden feature, and created a tweak out of it. Dubbed DetailedBatteryUsage, this new tweak allows you to unlock the hidden battery usage menu that Apple uses internally during development.

Want access to hyper-verbose details on your iPhone battery usage? Have a glance inside to see what it looks like on video…

Once you install the tweak, you’ll need to head to Settings → General → Usage → Battery Usage in order to find the additional details. As you’ll find, the hidden battery utility contains a much more detailed analysis than consumers find with the basic battery menu.

The general user many not find much of the information obtained by this hidden menu very useful, but those who are hawks with regard to battery life no doubt will. This tweak provides you with a hyper-detailed look into what’s using battery life, complete with line graphs.

Unlike the stock consumer battery usage menu, DetailedBatteryUsage allows you to view in-depth details on each app. Simply tap the app that you want to view, and you can discern battery usage in excruciating detail.

You can even access detailed information on system daemons that are running, which is an area typically off limits to the every day user. Details on each daemon can provide you with even more verbose details about how your iPhone is performing with regard to battery life.

If you’d like to try out DetailedBatteryUsage, venture over to the BigBoss repo on Cydia, and download it today. You’ll need to be jailbroken on iOS 8 before you’re able to do so. If you’ve yet to jailbreak, be sure to check out our iOS 8 jailbreak tutorial for more details.

    Now I find out which apps hog the most battery disable them for 2 days and then I re-enable everything when I realize that I’ve made my phone less useful.

    • Rowan09

      Phone tech is advancing but batteries are still working on old technology. I hope they find a solution soon but I don’t think it would be in the best interests of battery companies.

      • Ian Leon

        Look at “Graphene” it’s very exciting.

      • Rowan09

        It is but not commercially ready yet.

      • Ian Leon

        you said “I hope they find a solution”. This is the solution. If graphene was commercially ready we would have it already… DUH!

      • Rowan09

        Its not a solution because it’s not being used and not ready to be used. It’s just an idea right now and nothing more at this moment.

      • Ian Leon

        There are scientists in labs making these things and trying to figure out how to mass produce it

      • Ian Leon

        It’s the only groundbreaking thing that has happened to batteries(although technically graphene is used to make supercapacitors) in a long time.

      • Ian Leon

        I’m super certain that they’ll figure out how to massproduce it sooner than you think. As a matter of fact there are videos of people on YouTube making graphene capacitors in their garage. And you can see for yourself how simple it is to make. So yeah …

      • Ian Leon

        There’s also a video on TED that explains why graphene is the material of the future.

      • Ian Leon

        And remember you said “I hope they FIND a solution” not “I hope there already was a solution that they could pick off the shelf and put it in the device”

      • Rowan09

        Until its commercially ready it’s just an idea. I’ve looked extensively into graphene and it was deemed the thing of the future for about 3-5 years now and still nothing. I was looking to invest into the technology before it became the norm, but it’s still in beta form and that doesn’t mean it will ever leave beta.

      • Ian Leon

        Well, it looks like you really do have a lot of experience in this area.

      • Rowan09

        I was excited and wanted to invest so that’s why I did a lot of research and that was about 2 years ago.

      • SoylentGreen

        Its known in the trade world as ‘planned obsolecence’

    • Jonathan

      Yep, same.

  • Kai

    I used this tweak and found out that bb energy used up a lot of my battery. Does anybody know what bb energy is?

    • Chris Tangler

      backboard…at least im pretty sure

  • f96lrs

    back board

    • Mr.Adam

      I thought it meant baseband. Like how much the lte/3G modem used while using the app.

  • Lurker22

    iPhone Plus battery is amazing. I last easily an entire day now…

    • Rowan09

      Definitely the truth and it’s one of the main reasons I went for the 6 plus.

    • John

      Absolutely, I don’t think many people appreciate just how good this battery really is until they have used an iPhone 6 Plus for 24/36/48 hours and then realised they have fully charged it (maybe) once.

      I’ll be interested to see how attaching a watch via BT will affect the battery life on it though.

      • iNeedANameHere

        Leaving my beats studio wireless connected to my iPhone 6 all the time only seems to bump the battery usage 1-2% an hour. When I had a Pebble Watch with my iPhone 5S it was still in that 1-2% an hour range. Barely noticeable. Hopefully Apple Watch is the same or better.

      • Endriu Andrei

        and ipad battery it is even better…get it ? Your argument is invalid

    • becoolyolanda

      has anyone noticed a negative impact on the Plus Battery life after JB?

      • GadgetQueenn

        I have. It’s quite disappointing. 🙁

  • Fanboy 

    Apple is probably holding out on a miniature Arc Reactor for the iPhone 9S.

  • A man

    Thanks for sharing this tweak is super useful

  • ltcommander_data

    Just to confirm, the detailed energy logging in DetailedBatteryUsage doesn’t in itself reduce battery life does it?

    • I imagine that it’s always recording this anyway, to calculate the normal usage stats.

  • Shawn

    Its tweaks like this that tempt me to jailbreak.

    • BoardDWorld

      CCSettings is reason alone to jailbreak. iClean freed up 500MB on my nearly full 16GB iPhone, so that’s reason alone too (you need his beta repo). Then Power Tap and all those tweaks the blend in seamlessly with the OS like DetailedBatteryUsage make it more worth while. I’m hanging out for Aeternum & BattSaver.

      Anyone that hasn’t, jailbreak before 8.1.1.

      • Shawn

        I’m actually using iOS 8.1.1 and there better be something really impressive for me to jailbreak again seeing as my last few attempts with this jailbreak soft bricked my phone and 8.1.1 fixes my wifi problems.

      • BoardDWorld

        After removing UntetheredHeySiri I’m having no issues, battery was draining faster with that installed. I used the Mac Pangu which is the current official release.

      • John

        I assume this is why Apple haven’t added it as a standard feature… Drains the battery too quickly.

    • becoolyolanda

      this is why I come here …

  • Jordan Stevens

    After installing this on my 6, my phone started buggingn out. Uninstalled and it’s fine now.

  • Ian Leon

    How can I disable this hyper verbose logging. It’s probabbly a battery hog.

  • BoardDWorld

    Thanks for this Jeff, I hadn’t seen this one. The videos from you and EveryApplePro are indispensable.

  • Rahn

    I already have this battery usage menu on my unjailbroken iPod 5th gen iOS 8.0.2.

  • wdgewood

    I installed and noticed “ubd Background Activity” using 28%. I can’t seem to find any info online about this. Anyone know what this means and how to lower this figure?
