There's a lot to love about Lenovo's Moto Z line, which is now on its fourth iteration.

What's new: It's the one semi-successful effort at a modular smartphone, functioning as a perfectly good smartphone on its own, with the ability to add features like a better camera, smart speaker or projector via "Moto Mods."

  • Verizon used that capability to create with Motorola a 5G mod to make the Z3 its first 5G-capable phone and the Z4 will, naturally, also work with the 5G mod.

Yes, but: The Z line hasn't been enough of a commercial success to generate lots of add-ons. Indeed, there are no new mods to accompany this year's Moto Z4.

What's included:

  • New front and rear cameras use "quad pixel" technology to create sharper images. The Z4 also has Night Vision, Motorola's effort to offer dramatically better nighttime photography by combining parts of eight frames taken at different exposures. It's akin to the Night Sight feature on the latest Google Pixel phones.
  • The Z4 has a faster chip than last year's model, but it's a part of Qualcomm's midrange Snapdragon 600-series rather than last year's 800-series chip.
  • It has a big 3,600-milliamp-hour battery, with the option to add even more juice via a battery mod.
  • It carries a $499 suggested retail price. (Verizon, the only carrier to sell the Z4 directly, is offering a lower price for new customers.)

What's missing: It's not fully water-resistant, there's only one rear camera, and it uses older fingerprint sensor technology.

The bottom line: There are lots of other mid-range phones out there, but the Z4's versatility helps it stand out.

Tallying Trump's climate changes

The Trump administration's scuttling or weakening of key Obama-era climate policies could together add 1.8 gigatons of carbon dioxide equivalent to the atmosphere by 2035, a Rhodium Group analysis concludes.

Why it matters: The 1.8 gigatons is "more than the combined energy emissions of Germany, Britain and Canada in one year," per the New York Times, which first reported on the study.

Boeing's one-two punch

The grounding of Boeing’s 737 MAX was the worst crisis in the plane-maker’s century-long history. At least until the global pandemic hit.

Why it matters: Wall Street expects it will be cleared to fly again before year-end. Orders for what was once the company’s biggest moneymaker were expected to rebound after the ungrounding, but now the unprecedented slump in travel will dash airlines’ appetite for the MAX and any other new planes, analysts say — putting more pressure on the hard-hit company.

New downloads of TikTok, WeChat to be blocked in U.S. on Sunday

The Commerce Department issued Friday an order blocking new downloads of WeChat and TikTok in the U.S. as of Sept. 20.

The state of play: President Trump has been in a standoff with TikTok, threatening to ban the app if its Chinese owner, ByteDance, does not relinquish control to a U.S. company. A deal is in the works with the American tech company Oracle, but would need to go through before Sunday to prevent TikTok from being ousted from app stores.
