    Fun Fact: When you put on a MagSafe Silicone Case you will be greeted with a MagSafe logo that matches the color of your case!

    iPhone 12 Pro vs 12 RAM argument. If you're taking PRO only for the 6GB… DON'T. 4GB is enough.

    Posted: 25 Oct 2020 04:39 AM PDT

    So for a little bit o context. I'm an iOS apps developer and programming memory management of the apps both in foreground and in background is a part of my job. Because of that I need to understand perfectly how does multitasking in iOS works.

    RAM AND MULTITASKING:

    Apps use RAM in foreground and background right? The more RAM, the more of them can work in the background and you can multitask. That's how it works on computers, that's how it works on Android… but not on iOS. Let's look on how it actually does work on iOS.

    FOREGROUND:

    The app in the foreground can take up to ~60-70% of device's ram. That gives you about 2,5-3GB of RAM in iPhone 12. Is that enough? Yes! Typical iOS App takes about 100-300MB of RAM in the foreground. Games take about 1-2GB. Fortnite worked on iPhone 6S, so it simply cannot take more than 1,5GB of RAM. Be aware RAM does not make things go faster. CPU+GPU does. So having more RAM won't improve your frames per second count. You won't need more then 2GB of ram in the foreground. iPhone 12 covers you in that regard!

    OK, SO IF FOREGROUND DOESN'T NEED AS MUCH IT WILL BE USEFULL IN THE BACKGROUND RIGHT?

    Wrong!

    iOS on iPhones does not have a real multitasking (iPadOS does with 2 apps at once in the foreground). Every app that is more then 30 seconds in the background gets SUSPENDED*, no matter how much RAM you have. That's the Apple's choice to conserve battery and disallow background application to do god-knows-what in the background without you even realising it. That's why you can install 100 apps on your iPhone and it will work as good as with 10 apps. Apps will work properly only in the foreground, so they can only bloat you hard drive, but they cannot hang onto your other resources with their background mischievous tasks.

    SO HOW COME MY GPS AND MUSIC WOKRS IN THE BACKGROUND?

    Because there are exceptions to this rule:

    1. iOS can allow some tasks to work indefinitely through very special means controlled by the iOS system (not even the app itself!). GPS, Music, Microphone, Camera, VoIP calling. Apps with this features can work in the background. But even then, they've got a very restricted resources. iOS is saying to the app something like "Ok, here are the newest coordinates and you have 10 seconds to do something about them", or "Ok, you can record the microphone in the background and do some computing with the recording, but if you use too much resources for that I'll simply kill you. No bitcoin mining! No funny business".
    2. Application can "ask" iOS to let it finish some tasks that it started in the foreground, even if the user will push it to the background for more than 30 seconds. iOS won't let it stay opened for the infinite amount of time like in the real multitasking. It will assign it some additional time (not a lot of it) and that's that! This mechanism is just a safeguard with a very limited resources to finish what the app was supposed to do (Finishing the download of a file would be a good example). It's always very restricted, and Apple is very strict about it.

    SO WHY IPADS HAVE MORE?

    iPads can have 2 apps in the foreground so it needs up to two times more RAM. Also image/video editing apps are the exception to the rule: They actually need to put the whole video into the RAM to allow the real time editing of the video. And iPads are often used for the video/photo editing.

    SO WHY 12 PRO HAVE 6GB?

    To be honest I can only guess. My guess is that it's for the video editing (as iPhones pro are targeted mostly at a camera enthusiasts), just as described above. This argument + the fact that only iPhone 12 PRO got Apple RAW format feature (editing RAW format requires even more RAM, as raw files are huge) makes sense to me.

    *WHAT IS THIS SUSPENDED MODE:

    In suspended mode the app is "frozen" and cannot do anything but it saves your "state", allowing you to pick up where you left off (creating the illusion of working consistently in the background). The iOS decides when to completely kill the suspended app. More RAM will allow more apps in the suspended state, but it's not guarantee as the iOS can still kill apps for the energy conservation reasons. Unfortunately this process is not documented by Apple for iOS App developers.

    tldr;

    • Apps in foreground do not need more then 2GB of RAM
    • iOS does not have a real background, apps are suspended after 30 seconds in the background. No amount of RAM will change that.
    • Suspended app is "frozen" and it cannot do anything in the background. It will "unfroze" once in the foreground, creating an illusion of working the whole time.
    • Suspended apps get's killed once there is not enough RAM or the iOS system decides to kill it for the energy conservation reasons.
    • Everything that you can actually do in background on iOS (GPS, Music, VOIP) is strictly controlled by the iOS system to ensure minimum resources allocation and no funny business.
    • iPhone 12 PRO got 6GB of ram specifically for the image and video editing of the RAW files

    EDIT: As u/imahe wrote in a comment, the app is not killed after 30 seconds but it goes into a suspended mode. I've edited this article to reflect that.

    EDIT2: If you don'e believe me, maybe you'll believe apple support page and developer documentation

    After you switch to a different app, some apps run for a short period of time before they're set to a suspended state. Apps that are in a suspended state aren't actively in use, open, or taking up system resources. With Background App Refresh, suspended apps can check for updates and new content.

    ​

    Preserving your app's user interface helps maintain the illusion that your app is always running. Interruptions can occur frequently on iOS devices, and a prolonged interruption might cause the system to terminate your app to free up resources. However, users do not know that your app has been terminated and will not expect the state of your app to change. Instead, they expect your app to be in the same state as when they left it. State preservation and restoration ensures that your app returns to its previous state when it launches again.

    TIL there are three-finger gestures on iOS for undo, redo, cut, copy and paste.

    Posted: 25 Oct 2020 02:16 AM PDT

    I very often use the app Notes, which has no own interface for Undo/Redo itself and I always got annoyed when I deleted something by mistake.

    Swipe left with three fingers to undo.

    Swipe right with three fingers to redo.

    Double-tapping with three fingers opens a little menu with the controls.

    EDIT: You can use it wherever you can enter text, e.g. the Reddit App text fields or in Safari's search bar and so forth.

    EDIT2: As pointed out by u/13x666:

    „Double-tapping with three fingers opens a little menu with the controls. -> Actually, single tap is enough.

    ⁠three-finger pinch in to copy

    ⁠three-finger double-pinch in to cut

    three-finger pinch out to paste"

    PSA: Don’t get your screen protector installed by Apple, their tool scratches the polished stainless steel

    Posted: 24 Oct 2020 02:36 PM PDT

    Pictures of iPhone scratched by Apple's plastic screen protector installer

    Today, I got a new iPhone 12 Pro in silver with a belkin screen protector installed by the Apple Store. When I got home, I noticed a savage scratch near the mute switch and several severe scratching on the middle portion of the band scattered around.

    I called the store and was sent to a supervisor, and basically we were going to check out if what I said was credible. I went back and it looked like the iPhone couldn't have scratched because of the plastic screen protector installer.

    The supervisor managed to find one last iPhone 12 Pro in silver. He let me inspect it and it was flawless, gave it to the supervisor, then he passes it to the specialist that installs the screen protector.

    The specialist was pretty smooth with his process, but when he removed the iPhone from the tray, he noticed something strange. He showed it to the supervisor and he tried to wipe something off the stainless steel band, and I saw a glimpse of it. It was way more severe than what I got, it was vertical scratches this time, it looked like a claw dug into it.

    Now, they don't have anymore silver iPhone 12 Pro, but they let me have the graphite and would let me switch if they were ever back in stock. I didn't bother getting a screen protector even if the graphite stainless steel is PVD. Didn't wanna risk the last graphite iPhone 12 Pro either lol

    I'm just facepalming at myself for sarcastically saying to the supervisor, "imagine if this iPhone got scratched as well", and it actually did. I am so unlucky.

    At least the supervisor said they'll speak to the higher ups. The supervisor and specialist were really nice. But I'm just imagining all the people who got the screen protector by Apple.

    I looked at the tool, and it's pretty clean and smooth... when you look at it, you don't see how it could possibly scratch, but I get the polished steel is just delicate, maybe?

    Edit: Update to the scratches

    Why use the MagSafe charger?

    Posted: 24 Oct 2020 10:59 PM PDT

    I've been trying to wrap my head around this for a week now. Why do we want magnetic mounted wireless charging? The whole purpose of the wireless charger was grab and go. Put your phone down with no added energy, it charges. Pick it up and walk away and it's charged. Now you're tethered to the charger and it's back to square one with wired charging. You have to pull the charger off of your phone... what's the point?

    iPhones hold value better than Androids?

    Posted: 25 Oct 2020 09:19 AM PDT

    So I'm a die hard Android user. I have been thinking about switching to iPhone for a few months now as my entire family uses them and are always asking for help with them. Just makes sense to me.

    How does the value of iPhones hold up? If I switch, it'll be paying full retail for the 12 Pro and if for some reason I just hate it, I'd like to get most of the money back if possible.

    TIL - you can use the back tap feature on the MagSafe charger while your phone is charging

    Posted: 25 Oct 2020 10:00 AM PDT

    I recently started using the back tap feature (upgraded from X to 12 Pro and still getting used to the size, currently using this feature to get the screen to drop down cuz I have short fingers) and realized this morning that you can back tap the MagSafe charger itself while your phone is charging.

    Works as it normally would if you were to back tap your iPhone. Apologies if this is widely known and has been discussed here before. I've always enjoyed coming across little nuances like this.

    Any other random little tricks/tips you've come across that aren't widely known/discussed?

    Anyone find a MagSafe car mount yet?

    Posted: 25 Oct 2020 07:52 AM PDT

    Has anyone found a good magnetic car mount that works with MagSafe for the new iPhones? My old Spigen magnet mount is too small and fits inside the MagSafe circle so it doesn't work. I saw Belkin has one coming soon but not yet available.

    Why are people here such fans of MagSafe?

    Posted: 25 Oct 2020 12:13 AM PDT

    I didn't read too far into the topic, but from what I've seen there are some things that make me wonder why people love this so much.

    • from Posts I've read it seems to be pretty slow charging process. Sure, charging it over night wouldn't make a difference. But a quick charge during the day takes longer than with a normal cable from I've read. Or did I read the wrong posts?

    • some phones or cases seem to get like a branding from the metal of magnet on the back of the phone. Not a nice thing to have..

    • you still need a cable even when you do magsafe charging.

    So what is the reason people are using this? What are the pros? Or is it just the „new cool thing to have"?

    Lidar scan of my apartment on new iPhone 12 Pro

    Posted: 25 Oct 2020 10:26 AM PDT

    I got the monthly AppleCare plan with my iPhone 12 and it says I won’t be billed again until next year. Anyone else notice this?

    Accessibility Magnifier is so much worse now

    Posted: 24 Oct 2020 11:27 PM PDT

    This tool used to be amazing, I could easily take stills of tiny electronics and they would come out sharp and detailed - perfect for diagnosing solder issues and reading part numbers on chips.

    Examples here and here

    Now I take a snapshot and it looks awful. Before the snapshot and after

    It's like as soon as it takes a snapshot it applies a poop filter and smears all the pixels around. It's also buggy and often stops working with multitouch, and the various controls often disappear.

    Anyone else returning their 12 Pro to get a Max instead?

    Posted: 25 Oct 2020 09:10 AM PDT

    Just curious if anyone else here decided to get a Max after trying out the 12 Pro?

    For me its

    • I want a bigger screen
    • I want more battery
    • I want better photos

    My experience has been amazing with the iPhone 12. The biggest reason is I love the OLED screen and can't stop using my phone.

    But after using it so much for browsing and videos, I realized a larger screen would be better.
