I've been seeing a lot about Sodium-ion just in the past week.
While they seem to have a huge advantage in being able to charge and discharge at some fairly eye-watering rates, the miserable energy density would seem to limit them to stationary applications, at least for now.
Perfect for backup power, load shifting, and other power-grid-tied applications though.
Unfortunately Firefox doesn't have a replacement for the "Android System WebView" component, so any app that embeds a browser component (and oh boy is that a lot of them) will still be using Chrome.
There's a relevant ticket here: https://github.com/mozilla/geckoview/issues/167
It should be possible to have a shim that allows Mozilla's "GeckoView" component to implement the API, but - per that ticket, at least - most Android ROMs won't allow alternatives to the Google one.
The Firefox browser is genuinely great, but it's so far from possible to replace Chrome with it everywhere a browser is used.
Sony listened to their customers complaints and brought back the headphone jack for the 2nd generation Xperia 1.
Their phones continue to feature some of the best waterproofing (real world performance, and not just the rating they slap on it) in the entire industry.
That has never been a justifiable argument against the headphone jack, despite being an all-too-frequent one.
I've always been lambasted for this opinion, but I feel the same way about the charging cable and charger.
I do not want yet another 1 metre (if they're even that, most likely 3 foot) USB-C cable that barely reaches from the charger on the floor to the bedside table - and largely precludes actually using the phone while in bed - nor particularly the included charger. So many things need to be plugged in these days that single-output chargers are also basically e-waste.
Of course because some business genius had the idea that making the USB cable 0.9 instead of 1.8m saved them $0.06 per unit shipped, we all got lumped with those useless cables.
Now of course there will always be people for whom it's their first phone (or whatever situation), who do need those accessories. But all that requires is there to be a retail bundle with the now-accessory charger and cable. Preferably that bundle costs the same as the phone with them included does today and you get a token discount for the phone without them, although we all know it would never work that way :(
Unfortunately what's shipping today seems it would offer maybe half that.
For the batteries that were announced this past week, a larger-than-refrigerator-sized cabinet held a capacity of around 15kWh.
Around half the energy density by mass of Lithium batteries, and in the order of a sixth of the density by volume.
Now if only we could come up with a system where your car could be charged while stopped at traffic lights, we might be onto a winner (:
Considering however that the price of sodium is around 1-2% that of lithium, I expect we will see significant R&D and those numbers quickly start to improve.
