DASH hasn’t got better, no. But it is still in my view an excellent technology, I wish how it works was an open standard, USB-PD could certainly be used instead with some smarts.
Also it is a little unfair here because:
- the test had the screens on all the time. The DASH approach does the DC-DC conversion in the charger, so as the battery inside the OnePlus increases its voltage (from 3.7V to 4.2V typically), the DASH charger does exactly that. So there is no DC-DC conversion inside the phone. This keeps the phone cooler so it can recharger faster. The other technologies do not this so there is some DC-DC in the phone and if the phone is in use that heat from use competes with charging heat and the phone protects itself by charging slower. SO in the video this is showing the phone screens on which makes the DASH charging show maximum relative gain
Compare “inactive” vs “active” and see how DASH jumps ahead best in active
- DASH is only from OnePlus (using same tech as OPPO) meaning you must use their charger with their cable or accept 10W with all the thermal throttling problems. This proprietary is very annoying when you’ve got other than the OnePlus like some buds or a Powercore, where you’d like a Powerport which does it all.
Personally I use the DASH at home and Powerport and Powercore on the road, on the road I know I’m about to enter a period of use of the phone no-wall-socket so I just plug in Powercore proactively and then when stopped moving I have a fully charged OnePlus and recharge the Powercore next wall-socket-opportunity. It works.
