iPhone 7 Plus RAM issues

[Septembersrain]

Facebook, Spotify, Twitter, those three are horrendous with what seems like RAM leaks. When using those, all my other apps like Safari will refresh. That's been that way for me since I believe iOS 10. Prior to 10, I can't remember having half as many refreshes.

Now I just keep off background refresh, use app switcher to close Facebook and Twitter (Don't use Spotify anymore), keep location off for said apps, and everything seems okay.

Its not going to happen in real world or fake world use
Neither the ram or cpu/gpu is faster and that's a fact.

the ram in the 7 is the exact same as the 6s and SE

Also don't forget why the sentiment of the SE feeling faster than the 7 is legitimate...the big.LITTLE architecture in the 7 (the a10) is the culprit for this....tests that have the A10 using the little cores (where a brief exertion of CPU speed means the chips switch low to high power) show performance results that is lower than the A9, because the A9 is always in "full power" mode (there are no little cores). The A10's big cores are the most powerful chips in an iPhone yes but they aren't always in use; it is either-or (it is not a heteragenous design).

This is why some users see the SE and 6s perform smoother at low level operation vs the 7.

Ultimately you're right that 7 is factually the faster device overall, But in the real world use yes it certainly can also happen or feel that way at times for users for the SE (and 6s) to feel smoother operations because of the little cores in the A10 vs the A9.

Some apps will reload by design when coming out of a suspended state. Widgets especially do this because their data is usually time relevant, knowing what the weather was yesterday is rather pointless for example.

Have you experimented at all with background app refresh settings? Also does doing a reset make it temporarily better?

The ram in my 7 plus is not the same as the SE.
And the 7 is faster than the SE period.
Let's not get crazy now with nonsense claims.

Right now I have about 50 JetSamEvent just for today, and the day is not even over lol. Should I take it to the Apple Store?

There are no "nonsense claims" - I was just explaining why someone with an SE or 6s could experience faster animations or general performance. You might be unaware of how the A10 architecture works - It is 4 cores; only 2 of which are active at any given moment. 2 of them are low powered, 2 of them are high powered. The 2 low powered ones are weaker than the A9, and this is what leads to those perceptions people have of the 7 having stutters where the SE or 6s don't in general functions. I can see it when I mess around with my 6s and 7. There is no nonsense here, it is how the architecture works. The 2 high powered ones (big cores) are more powerful and that is where you will see the CPU gains, but they aren't always active.

The ram type of the 7 plus is the exact same as the SE, the amount is not. But you said the ram is faster which it isn't. They are both LPDDR4 on a 20nm process. There were some postulations that it would be a faster version of lpddr4 but that didn't pan out for this generation of iPhone. Ram amount is not the same as ram speed, which is what I made that initial comment from.

I was just trying to point out how that other poster who claimed they felt the SE was faster could be experiencing something that is simply a result of the little cores of the A10. That's all. Not attacking you or anyone else here.

Interesting theory but how can you back up that claim against my claim that iOS 10 is just sloppy and new iOS with new hardware is always some unique sloppiness on top even if overall superior experience to legacy devices on latest iOS (particularly last gen) that have been thrown around with public betas, dev beta, etc.

iOS testing on unreleased devices must be internal only and small and last minute if I had to guess

It might be more plausible that it could be software related. For the record: I find iOS 10 quite fluid myself. Those stutters I was remarking on or perceived slowdown on the 7 are not common place in my usage, and they occur rarely. But they do occur, and I'm not the only one who's noticed them present on the current generation more often than the previous generation when running iOS 10. Personally I do prefer iOS 10 to 9 fwiw.

I can try to back that claim up the way it makes sense to me:

• First off one needs to understand the general design of the A10 Fusion is akin to a big.LITTLE architecture, there is a powerful cluster and a weaker but more efficient/energy saving cluster. The little cluster has been identified as Zephyr, the big cluster as Hurricane. The code name for the A9 CPU cores was Twister.
  
  
• Second, we'd need to appreciate how only one cluster is active at any given time, I mentioned earlier it is "either-or" and what I meant is that either the more powerful cluster is active or the less powerful cluster is active, not both. This means the clusters switch. When you swipe between screens or type on the keyboard, that is probably the little cluster. Or when you receive messages and emails, the little cluster. But anything more intensive like gaming or watching videos will be big cluster. (This is how Apple designed the A10, it is not indicative of every big.LITTLE chip)
  
  
• Third, if you look at a die shot (via Chipworks) of the A10, you can see how tiny Zephyr is (the little cluster) vs Hurricane (the big cluster), we know it consumes 1/5 the power of the big cluster as Apple states in their iPhone 7 reveal conference.
  
  
• We can compare Zephyr to the A9 and its apparent the A9 (which is a fair node comparison as the A9 and A10 are essentially on the same node process) is a much more powerful chip. Chipworks has a nice writeup of all the parts of the CPU they are able to spot in the A9 as well for comparison sake, and I presume they are correct.
  
  
• Hurricane (big cluster) is responsible for the A10 benchmarks we see, or really any performance gain we see with the A10 and it is the "evolution" of Twister (A9 chip)...it is the "star" of the A10.
  
  
• I would say there is a verifiable 0% chance Zephyr is more powerful than Twister considering they are both on the same node and we have die shots to look at to compare the size of the chips. As a result it is extremely likely when Zephyr (the low powered cluster) in the A10 is active that it cannot run CPU processes as *fast* as the A9 can.
  
  
• Think of the Zephyr as something like a Toyota Prius that gets great mileage and Twister (A9) as a Ferrari. Think of Hurricane (A10 big cluster) as an even faster, newer Ferrari. When you're in the Prius, you aren't going to go as fast as the Ferrari whether its new or old.
  
  
• Further, think of the A10 as a Prius that can morph into a Ferrari (and vice versa) but it can only be in Prius mode or Ferrari mode at any given time. When it is in Prius mode, it isn't as fast as the Twister (A9) Ferrari.
  
  
• I believe this is why some people experience the SE or 6s faster at certain times vs the 7

Hope that helps, thadoggfather. The die shots are right there. This is why I find it very plausible. Again, it very rarely happens but I have noticed the 7 does stutter at times the SE or 6s do not, and I'm not the only one who has anecdotally experienced it.


Sorry for the tangent here OP none of this really helps your RAM issue out
