Technology It’s not your imagination: Phone battery life is getting worse

Phone makers promise “all-day battery life.” Sure, and you haven’t stolen any of the kids’ Halloween candy.

If you recently bought a new flagship phone, chances are its battery life is actually worse than an older model.

For the last few weeks, I’ve been performing the same battery test over and over again on 13 phones. With a few notable exceptions, this year’s top models underperformed last year’s. The new iPhone XS died 21 minutes earlier than last year’s iPhone X. Google’s Pixel 3 lasted nearly an hour and a half less than its Pixel 2.

Phone makers tout all sorts of tricks to boost battery life, including more-efficient processors, low-power modes and artificial intelligence to manage app drain. Yet my results, and tests by other reviewers I spoke with, reveal an open secret in the industry: the lithium-ion batteries in smartphones are hitting an inflection point where they simply can’t keep up.

“Batteries improve at a very slow pace, about 5 percent per year,” says Nadim Maluf, the CEO of a Silicon Valley firm called Qnovo that helps optimize batteries. “But phone power consumption is growing up faster than 5 percent.”

Blame it on the demands of high-resolution screens, more complicated apps and, most of all, our seeming inability to put the darn phone down. Lithium-ion batteries, for all their rechargeable wonder, also have some physical limitations, including capacity that declines over time — and the risk of explosion if they’re damaged or improperly disposed.

  • Ghan Ghan:
    We could use some rain.
  • The Helper The Helper:
    I am not complaining though Hurricanes are not fun I have been through alot of them
  • Blackveiled Blackveiled:
    I evacuated for it just incase since I live in La Porte pretty much right on the water (in Houston area). Didn't see anything. It's a good thing for me anyways.
  • Ghan Ghan:
    It's too bad that Blizzard messed up so terribly with Reforged.
  • Ghan Ghan:
    Still has a 0.6 user metacritic score.
  • Ghan Ghan:
    (Out of 10)
  • Varine Varine:
    I haven't even tried it yet because everyone said it sucked. How do you get .6 out of ten?
  • The Helper The Helper:
    I am waiting for Dwarf Fortress to come out on Steam then I am on it.
  • Accname Accname:
    I play Dwarf Fortress from time to time.
  • Accname Accname:
    Its Okay.
  • Accname Accname:
    But the performance is sub-par. Does not seem to be well optimized.
  • Varine Varine:
    Is the Steam version coming with a graphical overlay or is it using the ASCII graphics still?
  • tom_mai78101 tom_mai78101:
    Steam version has the graphical overlay.
  • The Helper The Helper:
    Steam Version has graphics, a new interface and will be integrated in the steam mod stuff
  • Blackveiled Blackveiled:
    I didn't think WC3 Reforged was that bad. It pretty much did what it stated (to me at least), but then again I can care less about reforged campaigns and all that. I just care about gameplay.
  • Varine Varine:
    I think people were hoping for a resurgence in mod support. I have little interest in the actual game tbh
  • Varine Varine:
    Plus I know they added that Dota precedent clause where Blizzard can steal your shit which isn't cool.
  • Ghan Ghan:
    They sold Reforged to the community as primarily a huge graphical uplift with high res textures and redone cinematics.
  • Ghan Ghan:
    They even showed one of the redone cinematics at Blizzcon and that very cinematic wasn't even in the released game.
  • Ghan Ghan:
    So I think folks were angry about that.
