Apple's default settings aren't necessarily your settings
Every new device arrives as a kind of blank contract between the maker and the user — full of assumptions that may not fit any particular life. The iPhone 12, powerful and polished as it is, ships with Apple's defaults rather than yours. In the weeks following its October 2020 release, thoughtful observers noted that a handful of deliberate adjustments — to 5G behavior, battery management, privacy permissions, and daily rhythms like sleep — could quietly close the gap between what a device is and what it becomes in a person's hands.
- A phone that constantly hunts for 5G signal in areas without coverage is quietly draining its own battery — a hidden cost most users never think to question.
- Default notification settings expose private messages on the lock screen and let calls and alerts interrupt sleep, eroding both privacy and rest without the user ever choosing either outcome.
- Dark mode and manual brightness control work in tandem on OLED screens to meaningfully extend battery life, but neither is enabled by default — they require the user to seek them out.
- iOS 14 introduced new home screen and App Library behaviors that, left unconfigured, can scatter apps and clutter the experience rather than simplify it.
- A ten-minute review of Settings > Privacy often reveals a quiet accumulation of permissions granted in haste during setup — location, camera, and health data handed over just to move forward.
- Each of these adjustments is small in isolation, but together they shift the device from Apple's vision of a generic user toward something that actually fits the person holding it.
The iPhone 12 arrives fast, sleek, and loaded with iOS 14 — but Apple's factory defaults are built for a hypothetical user, not any particular one. A few deliberate changes, each taking only minutes, can meaningfully reshape how the phone performs and how it fits into daily life.
The most consequential early decision involves 5G. In areas where coverage is thin or absent, leaving 5G enabled forces the phone to constantly search for a signal it may never find, burning battery in the process. Switching to LTE in Settings > Cellular costs nothing in real-world speed and buys back meaningful battery life. For those with reliable 5G service, it's worth visiting Data Mode settings to confirm whether the phone is configured for high-quality streaming or conservation — the carrier default may not match what you actually want.
Smaller friction points accumulate quickly. iOS 14 changed incoming calls to appear as a compact banner rather than a full-screen takeover — less intrusive, but easier to miss. Users who prefer the old behavior can restore it in phone settings. Notification previews on the lock screen are hidden by default for privacy, but can be set to always visible for those who'd rather see a message without unlocking the device first.
Battery life rewards a two-part approach: enabling dark mode converts bright white interfaces to black on OLED screens, where dark pixels consume less power, while disabling auto-brightness puts manual control back in the user's hands. Do Not Disturb, scheduled for overnight hours, silences alerts without deleting them — a small setting with a genuine effect on sleep quality, with options to allow emergency calls through.
Readability adjustments like text size and bold text live in Display & Brightness settings. Face ID can be trained on an alternate appearance — useful for those whose look changes with glasses, a beard, or other variables. The App Library introduced in iOS 14 can be configured to receive new downloads directly, keeping the home screen uncluttered. Control Center is fully customizable, and a review of privacy permissions in Settings reveals, for most users, a quiet accumulation of access granted in haste during initial setup.
None of these changes transforms the device into something unrecognizable. Together, they make it feel less like a product and more like a tool shaped to the person using it.
You've just unboxed your new iPhone 12. It's sleek, it's fast, and it came loaded with iOS 14 straight from the factory. But Apple's default settings aren't necessarily your settings. A few quick adjustments—the kind that take minutes, not hours—can transform how the phone actually feels in your hand and how long it lasts between charges.
Start with 5G, the headline feature of these new phones. If you live in an area where 5G coverage is sparse or nonexistent, leaving it enabled is like keeping a door open in winter. The phone will constantly hunt for that faster signal, draining battery in the process. Apple built in a Smart Data feature that's supposed to switch automatically between 4G LTE and 5G based on what you're doing, but if you're not seeing the speed benefit, there's no reason to pay the battery cost. Turn it off by going to Settings > Cellular > Cellular Data Options > Voice & Data and selecting LTE. You can always flip it back on later. If you do have reliable 5G service, check Settings > Cellular > Cellular Data Options > Data Mode to choose between allowing more data on 5G (which enables high-quality video calls and HD streaming), Standard, or Low Data Mode. The default depends on your carrier, so it's worth verifying it matches what you actually want.
Next, address the small annoyances that add up. iOS 14 changed how incoming calls appear on your screen—instead of taking over the whole display, they now show as a small notification at the top. It's less disruptive, sure, but it's also easy to miss. If you prefer the old full-screen alert, go to Settings > Phone > Incoming Calls and tap Full Screen. Similarly, Face ID hides notification previews on your lock screen by default for privacy. If you'd rather see who texted you without unlocking the phone, go to Settings > Notifications > Show Previews and select Always.
Battery life is the constant concern. Dark mode genuinely helps—it converts white backgrounds to black, and on OLED screens, black pixels use less power. Enable it at Settings > Display & Brightness. While you're there, consider disabling auto-brightness. Yes, the phone can adjust screen brightness automatically based on ambient light, but manual control gives you the power to keep brightness lower and extend battery life. Turn off auto-brightness at Settings > Accessibility > Display & Text Size. Dark mode and manual brightness control work together to noticeably extend how long you can go between charges.
Do Not Disturb is perhaps the most underrated feature on any iPhone. By default, it's off, which means your phone will ping and beep all night long. Turn it on and set a schedule—say, 10 p.m. to 7 a.m.—and your phone goes silent. Notifications still arrive; they just don't wake you. You can allow repeat calls from the same number to ring through in case of emergency, and you can whitelist calls from your favorites. It's a small setting that genuinely improves sleep quality.
For readability, go to Settings > Display & Brightness > Text Size and adjust the slider to your preference. Bold Text, just below it, adds another layer of clarity. If Face ID isn't recognizing you consistently—perhaps you've grown a beard, or you wear glasses sometimes and don't other times—go to Settings > Face ID & Passcode, enter your PIN, and select Set Up An Alternate Appearance to enroll your face a second time.
With iOS 14 came the App Library, a drawer that holds all your apps without cluttering your home screen. When you download a new app, you can choose whether it lands on your home screen or goes straight to the App Library. Go to Settings > Home Screen and select your preference. Control Center, accessible by swiping down from the top-right corner (or up from the bottom on older iPhones), is your quick-access hub. Customize it at Settings > Control Center > Customize Controls. Add or remove features with the green plus and red minus buttons, and drag them into your preferred order.
Finally, spend ten minutes on privacy. When you first set up your phone, you're bombarded with permission requests—location, camera, photos, health data. It's easy to approve everything just to move forward. Go back through Settings > Privacy and review what each app can access. You'll likely find you've granted permissions you don't actually need. These twelve adjustments won't transform your iPhone into a different device, but they will make it feel more like yours—faster, quieter, and lasting longer between charges.

Apple's default settings aren't always the best settings to help you get the most out of your iPhone— CNET
La Conversación del Hearth Otra perspectiva de la historia
Why does turning off 5G actually save battery? Isn't the phone just supposed to be smart about it?
Apple built in a feature called Smart Data that's supposed to switch automatically, but the phone still has to search for 5G signals constantly. If coverage is spotty where you live, that searching itself drains the battery faster than just staying on LTE.
So you're saying the default settings are actually working against you?
Not against you exactly, but they're designed for an ideal scenario—good 5G coverage everywhere. If that's not your reality, the defaults become liabilities.
What about dark mode? Does it really save battery, or is that just marketing?
On OLED screens like the iPhone 12 has, black pixels literally use less power than white ones. It's physics, not marketing. Combined with manual brightness control, it's one of the few settings changes that actually extends your day.
Do Not Disturb seems obvious, but why isn't it on by default?
Apple assumes you want to be reachable. But most people would sleep better if their phone was silent at night. It's a setting that should probably flip the other way—on by default, with an option to turn it off if you need to be available.
What's the privacy thing really about? Are apps stealing data?
Not stealing exactly, but you're probably granting permissions you don't need. An app might ask for location access, and you approve it just to use the app, even though it doesn't actually need to know where you are. Spending ten minutes reviewing those permissions is time well spent.
After you make all these changes, does the phone feel different?
It does, actually. It's quieter, it lasts longer, and it feels more like it's working for you instead of against you. These aren't dramatic changes, but they're the difference between a phone that frustrates you and one that doesn't.
