You are not crazy! Some iPhones are slowing down and you can blame Apple: 4GB vs 6GB RAM iPhone test
Now, I’m not saying Tim Cook & Co are going out of their way to slow down your iPhones – not at all, but… Let me explain!
If your iPhone is getting slow, then you deserve to know exactly why – this is the secret Apple and iPhone reviews won’t tell you
Pro is better after all.
In a nutshell (and if you’re in a hurry and need to go right now), older iPhones seem to need more RAM, which is the reason they are killing apps in the background and effectively slowing down your whole experience of using the phone. Giving recent iPhones only 4GB of RAM was a choice Apple made years ago and one that can’t be undone. At least I don’t believe it can – I doubt software update can solve the RAM problem. But if you want to dive into a bit more detail, you can keep reading…
First of all, as it turns out RAM matters. Even on iPhone! And I say “even on iPhone” because there used to be this “assumed rule” in the smartphone that “Android phones need a lot of RAM to run fast, and iPhones… don’t”. While I still believe iPhones don’t need nearly as much Random Access Memory (don’t confuse RAM with storage) to match Android’s performance, today, the story has changed a little…
As I explained in the beginning, my iPhone 13 regularly decides to kill apps running in the background, and I already figured the reason might be that the vanilla iPhone 13, just like the iPhone 12, iPhone 11, and iPhone XS, only comes with 4GB of RAM (older iPhones have 2-3GB of RAM). But, of course, I had to put my theory to the test, which went like this…
iPhone 13 vs iPhone 14 Pro RAM test shows why older iPhones might be slowing down – but is Apple slowing down your iPhone on purpose?
The obvious way to test RAM performance is to start opening apps, and then start reopening them to see if the iPhone killed any of them. So, I opened a mix of 20 popular apps on my iPhone 13 (apps everyone uses), and my iPhone 14 Pro at the same time.
Here are the results…
iPhone 13 (4GB RAM, LPDDR4X) | iPhone 14 Pro (6GB RAM, LPDDR5) |
---|---|
20 apps running in the background | 20 apps running in the background |
0/20 app reloads when reopening the apps immediately (the most common RAM test; not the best way to test RAM) | 0/20 app reloads when reopening the apps immediately (the most common RAM test; not the best way to test RAM) |
30 apps running in the background | 30 apps running in the background |
10/30 app reloads when reopening the apps 30 minutes later (better replicates real-world) | 1/30 app reloads when reopening the apps 30 minutes later (better replicates real-world) |
Is Apple slowing down your iPhone? Yes and… no!
As you can see, my iPhone 14 Pro was able to keep more apps running in the background compared to my iPhone 13. But let’s answer the question everyone might be asking right now – is Apple slowing down your iPhone?
First of all, it must be clear that this isn’t the “Batterygate” type of scandal some might be looking for – in case you didn’t know, Apple was “caught” throttling the performance of older iPhone models to preserve the condition of their batteries without giving users a choice (which was the real problem); the legal dispute ended with a $113M fine for Tim Cook & Co.“RAMgate” – if you want a bit more drama in your life, is a design decision that went into the making of cheaper iPhones to bring down costs – Samsung, Google, Motorola, Huawei, etc., also tend to equip their cheaper models with less/slower RAM.
Should you buy a Pro iPhone? Apple’s Pro iPhones will stay faster for longer; choose iPhone 14 Pro and iPhone 15 Pro over the vanilla models if money isn’t an issue
Apple seems to know 4GB of RAM isn’t enough for iPhone anymore. iPhone 15 is expected to come with 6GB of RAM, while iPhone 15 Pro should have 8GB.
Now, that begs another logical question – should you buy a more expensive iPhone, with more RAM if you want it to stay faster for longer? And the simple answer is… Sure.
Apple’s Pro iPhones come with a number of premium design upgrades over the vanilla models but one that doesn’t get enough attention, and one that’s arguably more important than almost any other, is the extra and/or faster RAM you get by buying a Pro iPhone. The number of apps we use on a daily basis is increasing, while some of them are also getting more RAM-hungry, which means buying an iPhone with more/faster RAM might be a good idea – if you want your phone to be faster now but also, stay faster tomorrow.
You might want to consider this when picking between a vanilla and a Pro iPhone
However, you might know that last year Apple chose to set apart the vanilla iPhone 14 and iPhone 14 Pro by giving them two different chips (A15 Bionic for the iPhone 14 and A16 Bionic for the iPhone 14 Pro). The interesting thing here is that despite running on two different chips, both the vanilla and Pro iPhone 14 come with 6GB of RAM, which means they should perform similarly.
What you might not know is that the vanilla iPhone 14 uses LPDDR4X RAM, just like the iPhone 13 and iPhone 13 Pro, because it’s using the same A15 Bionic as them. Meanwhile, the iPhone 14 Pro uses the newer LPDDR5 RAM standard, which is said to be 50% more efficient, and might be another reason it could (potentially) stay faster over time. Remember, with an SoC like Apple’s, RAM is baked into the chip – it’s not like you can upgrade it as you go (even if you’re Apple).
And, of course, by opting for a Pro iPhone, the cherry on top is that you’d also get the natural advantage of having a newer chip, which (in Apple’s case) is directly related to RAM performance but also will be… faster. The whole chip differentiation Apple decided to introduce is a whole other topic that I can’t get into now.
Reportedly, Apple is skipping the upgrade to faster LPDDR5X RAM for the entire iPhone 15 series due to the nature of TSMC’s processing for the new A17 Bionic chip. That being said, it is expected that iPhone 15 Pro and iPhone 15 Pro Max will be the first iPhones to feature 8GB of RAM, while the vanilla iPhone 15 models should stick to 6GB. LPDDR5X is reportedly coming to iPhone 16 thanks to an upgraded manufacturing process.
Did Apple make a mistake by giving recent iPhones less RAM? 4GB is not enough in 2023
As the great Bob Ross once said, we don’t make mistakes – we have happy accidents!
Finally, the last question (promise!) I’d like to address is: “Did Apple make a mistake when it gave recent iPhones only 4GB of RAM?”
The first iPhone with 6GB of RAM was the iPhone 12 Pro, while the latest iPhone to feature only 4GB of RAM is the iPhone 13 (and my 13 mini, of course). As an iPhone 13 mini user, my answer to the question above must me… “yes”. My test seems to prove Apple should’ve opted for more (and probably faster) RAM sooner.
On the other hand, my iPhone 14 Pro was sitting dead on my desk for a week, when I plugged it in to open one of the apps I had used a week ago (!), and find it ready to go – exactly as it was when the 14 Pro died a week ago, which… blew me away. It also showed me the convenience I’m missing out on by using an iPhone with less/slower RAM. So, again – yes, you should buy an iPhone with more RAM if you can because it might be the difference between a slower/faster iPhone in a few years time.
