The only benefit I've really made sense of with hybrids is their engine emissions aren't localised to the neighborhood where they're charged overnight. Apart from that, I can't think of anything else.
Conventional jet engines run at RPMs in excess of 20000rpm. To get this same speeds for the same mass flown rates of say a J79 (F4-Phantom) you'd be looking at some massive electric motors. Conventional jet engines would be using electric motors if they were light enough already.
There is a reason Rolls-Royce UltraFan uses a speed reducing gearbox for it's fan blades and not an electric motor.
More to the point above, at hypersonic speeds, using a conventional compressor is sort or useless unless you can keep your air cool.
I highly recommend AccuBattery for Android. I have been using it for a few years now and I saw a noticeable difference on my Pixel 3a XL compared to use on previous smart phones. I now have a Pixel 6 and its nearly 2-years old and the battery lasts well beyond 30-hrs with combined use.
