iOS 5 battery icon (full)

Longer battery life is one of those things that’s usually at the top of people’s smartphone feature wish list. I know it is mine. But unfortunately, there hasn’t been any major new developments in mobile battery tech over the last few years.

Companies like Motorola are figuring it out though. The Google-owned maker just introduced a new handset with a staggering 48-hour battery life. And according to this patent application just published by the USPTO, Apple is too…

AppleInsider points to a new Apple patent filing published by US Patent and Trademark Office this morning that covers a mobile device control system that can powers down components of the device based on context, to save battery power.

“To help reduce power consumption, Apple proposes a system that can compare the estimated time period a user will spend on their device with battery reserves, determining whether the device has sufficient power to last for said period. If the battery does not have sufficient power, the system will adjust “one or more characteristics” to conserve energy.

In one embodiment, the system can store charging locations and corresponding device data by using an on-board GPS radio. Example data can be type of power source, typical charge time, and typical travel time to and from locations. The device then stores the typical charging locations and usage patterns in a database, from which a power management scheme is calculated.”

The patent application, which was first filed in 2012, is titled “Power management for electronic devices,” and lists Michael I. Ingrassia, Jr. and Jeffery T. Lee as its inventors. The former, Ingrassia, is currently a senior software engineer at Apple.

As with most Apple patents, it’s unknown if we’ll ever see this invention make it into consumer products. But, as devices continue to get smaller, and more capable, we imagine that software tweaks like this are going to become invaluable.

I have to say, this idea seems pretty ingenious. What do you think?

  • Nice idea, but wont it consume battery by using the GPS to locate the nearest source?

    I can lower the brightness/close apps/turn off LTE on my own

  • Schryliam

    They should make a system that when you are home you data turns off and turn on wi-fi
    When on lockscreen instead of turning wi-fi off they should make the power of the wi-fi lower.
    When walking back outside a pop up that asks if you want to turn on data. Something like that

    • Adil Hussain

      …And something like that would require location services (i’d expect), which means more battery drainage 🙂

      • Schryliam

        That’s true. But location services drains less battery them wifi or data does. And alot of people have wifi and data on at the same time, and by this way it saves battery. Plus location services is always refreshing to locate your exact position. They could make a 10 min interval

        And if they make that your 3g turns off after locking your iphone spares alot battery too.
        Only switching back to 3g takes so long.
        And there are so many more ways to save battery

    • Luis Estrada

      Like Battery doctor on an jailbroken device

      • Schryliam

        Indeed
        But the only thing batterydoctor does from the things I said it switching off 3G after locking.

  • MarcPhilippeB

    yeah, but still, the capacity of the battery stays the same. Even on the lowest posssible consumption level it won’t last one day heavy usage.

  • MarcPhilippeB

    And does somebody know how Motorola does it?

    • Henley

      Basically in the “Octa-core” they shut off the inactive usage like saying checking a email or sending a message. They do this with the RAM as well. So yeah it’s just basically shutting off inactive parts of the phone when it is not needed. You’re welcome.

    I have another idea: A battery that actually withstands any usage pattern for a day.
    *cough* Motorola *cough*

    • Guest

      For crying out-load! They didn’t even release the droid maxx

      • Falk M.

        Keep calm… They claim 48h usage time.
        Even if they totally overrated that, it will surely last a good day of a bit more intense use.

    • Saria Hajjar

      *cough* Looser *cough*
      Not because you chose Motorola but because you sound very geeky, and not in a good way.

      • Falk M.

        I’m an iPhone user, thank you.
        Next time try belittling someone based on facts and not guesses.

    Interesting location based power profile switching using GPS. Anyway if GPS is a power hungry option why not include the option to use cell-id?
