Apple has put such an emphasis on increasing the performance of their mobile chips and honestly I just don’t know why at this point. I don’t need nor want to play Resident Evil 4 Remake on my phone. I much rather have more battery life. With that said I suspect this is probably a software issue and can probably be resolved with an update.

Increased performance in case of this architecture style actually contributes to better battery life. The faster any one operation can finish, the faster the whole core can go back to sleep - remember, just idling has a very significant energy drain.

I'm an embedded engineer and I'm always surprised at how slow software is. I bought a new laptop that had Windows 11 pre-installed, SSD, all the bells and whistles.

Not taking it up is not utilizing the hardware properly.

On the hand, I agree. But on the other hand, I love the innovation here, because it could lead us to a day where your phone is your computer. Plug it into a keyboard and monitor and get to work.

Samsung DEX and Windows Phone Continuum. The market has already spoken.

People keep foisting DEX forward as a reason why convergence isn't demanded by the market.

But, demand is created by early adopters (the people here), and those people don't use DEX because they don't use Samsung, due to Samsung being considered janky-to-insecure, depending on who you ask.

It's supposed to, but current reports indicate that battery life is the same or worse with this lineup (maybe the overheating situation is to blame)

Samsung is the Android market leader.

  * A developer who produces faster code is more expensive to hire.  
  * Any developer - good or bad - will deliver the same feature faster if they implement it naively, rather than digging deep and optimizing it.  
  * A slow implementation might cost less to maintain later. 
  * The vendor doesn't pay the cost of their code being slow. It's the customer that has to pay for the hardware upgrade.
Each company just edges the line between most profit (by cheaply producing slow software) and complete death (by producing software so slow your customers leave instantly a competitor shows up, e.g. Discord killing Skype)

I can't wait for CPUs to stop developing. Companies will have to return to efficiency in order to actually support more features.

That’s great as long as the software doesn’t change to fill the new performance headroom. Unfortunately, software seems to follow the same law as bureaucracy: expand until all available resources are consumed.

13 was solid AIUI, 14 had and still has battery issues and 15 runs hot and possibly battery issues too? Let’s play iPhone defect excuse bingo: - it’s just indexing data it will be ok after a week/month.

I mean is it wrong? It seems plausible to me: we know it does a lot of stuff in the background to make photos searchable, and afaik that's not really synced. When a phone is suddenly logged into iCloud and has tens of thousands of photos available, is it that implausible that it'd run hot for a while as it analyzes photos?

Not trying to excuse anything here, if you can provide a reason to believe it's not caused by those background processes I'm completely fine with the explanation that iOS is just buggy or the hardware has heat issues. Frankly the behavior does sound pretty bad even if it's "just" the photo analysis thing, the obvious solution would be to 1) make the analysis sync with the photos, and 2) make the background processing slow enough to not notably increase heat/decrease battery life, and 3) have a place in the OS where you can see the progress and tell it to go as fast as possible. Their philosophy of hiding everything from the user doesn't seem to be working well here.

Taking it up for no visible performance gain is wasting, not utilizing.

It needs to identify each dog in your photos library to put them in their own album and figure out which dogs or people to suggest for the photo widget. Which is to say it’s not unimaginable that photo indexing is part of it.

If so it’s a ridiculous trade off to make. Someone spending $1000-2000 doesn’t want a hot draining phone just so they can search “dog” in their photo album on day 1 or 2. They should throttle it - much better to tell the user the feature isn’t ready yet or something. Or you know, give the user the choice of running that feature fast or slow - but that would be anathema to Apple. Ps I am an Apple fan boi. Own lots of…

They should throttle it more and have a screen in Photos where you can see progress and ask it to go as fast as possible.
