Way back in the olden days, back to the yesteryear era when iPhones and smartphones would fit into you pocket, a battery would last most of the way through the day. What’s changed?
Not surprisingly, everything has changed except the iconic iPhone-cum-smartphone design (flat slab of glass, rounded corners) and battery life. Displays are bigger. iPhones stick out of butt pockets more than ever. And batteries barely make it through the day.
Oh, one more thing. What we accomplish on an iPhone during the day vastly exceeds the earlier iPhones that would fit into your hand, too. Geoffrey A. Fowler:
It’s not your imagination: Phone battery life is getting worse
Uh, maybe. Possibly. Yes. But a definite maybe. A day later, Joel Hruska:
Phone Battery Life Is Either Getting Worse or Improving Dramatically
Those are not the only options. It could be that battery life is roughly the same as it’s always been. About a day. At the end of an average day, with a relatively new iPhone, you might have 20-percent battery left. Or, you may need to top it off earlier just to get through the day. My old iPhone 7 Plus almost made it through two full days.
Unless I used it. See the problem? Usage varies. So, battery life varies. My Best iPhone Battery Tips has a list of helpful hints to get a little more juice, but it won’t matter much. iPhone batteries– like those of Android counterparts– barely make it through an average day.
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.
Most such battery life tests are not akin to real world usage. They run loops of this or that for hours to see how long a battery will last, but those are not real world conditions. Consumer Reports did something different. It uses a robotic finger that performs tasks you and I would do.
The robot browses the internet, takes pictures, uses GPS navigation, and, of course, makes phone calls. For the sake of consistency, we run all smartphone battery tests with the display set to 100 percent brightness.
What happened? More than brand, more than battery size, more than display, battery life is usage based. Just like always.
iPhone batteries last about a day, give or take a few hours.
