Yes, the iPhone 15 definitely turns off, and you can do it in a few ways: by holding the Side button with a Volume button and sliding the power-off icon, through the Settings app (Settings > General > Shut Down), or by asking Siri to power it down, though it's generally recommended to leave it on for updates and backups.
The Always-On display (right) dims the screen but keeps some information like the clock visible. The iPhone's always-on display, which debuted with the iPhone 14 Pro and continues with the iPhone 15 Pro and iPhone 16 Pro, is a rather stark departure from Android phones that had the feature before it.
Three-finger gestures on iPhone primarily activate accessibility features like VoiceOver (for screen reading and navigation) and Zoom (magnification), allowing scrolling, zooming, and text manipulation (copy/paste/undo) with specific taps and drags, though some text actions work without VoiceOver enabled for quick editing. Common gestures include three-finger double-tap to toggle VoiceOver speech, triple-tap for the screen curtain, and pinching/spreading with three fingers for copy/paste actions, notes this YouTube video.
From overheating to screen freezes, the iPhone 15 (Pro and Pro Max) have their quirks. And when you find yourself staring open-mouthed at your screen because your iPhone suddenly decides to pull weird antics, you know: this isn't user error. This is just … frustrating.
Most people leave their phones on 24/7, rarely considering the benefits of a full shutdown. However, according to the National Security Agency (NSA), regularly turning off your phone is a good habit for several important reasons.
It's especially important to avoid exposing your device to ambient temperatures higher than 95° F (35° C), which can permanently damage battery capacity. That is, your battery won't power your device as long on a given charge. Charging the device in high ambient temperatures can damage it further.
You can see if someone is actively checking your location on an iPhone by checking the "People" tab in the Find My app (if you're sharing) and looking for purple arrows next to System Services in Settings > Privacy & Security > Location Services, which indicate recent access, but there's no single log for who checked your exact spot in Find My unless they are using Precision Finding, which notifies you, or you're getting alerts for misplaced AirTags. The primary way to know who has access is to review who you're sharing with in Find My, while system service arrows show if your location was used recently by iOS features.
The 20-80 rule for iPhones suggests keeping the battery charge between 20% and 80% to minimize stress on the lithium-ion battery, thereby extending its overall lifespan and health by avoiding the high-stress points of full discharge (0%) and full charge (100%). While not a strict necessity for daily use, this practice reduces battery degradation by avoiding deep discharges and the taxing final 20% of charging, helping maintain battery capacity longer, though modern iPhones have built-in features like Optimized Battery Charging to manage this.
Yes, the iPhone 15 is widely considered a worthwhile purchase in late 2025/early 2026, especially if upgrading from older models (iPhone 11-14) due to its excellent value, significant camera upgrades (48MP sensor, better HDR/Night Mode), Dynamic Island, USB-C port, A16 Bionic performance, and comfortable design, though its 60Hz screen is a drawback compared to newer Pro models. Current iPhone 15 users generally don't need to upgrade unless wanting the Pro models' 120Hz display or newer AI features.
The iPhone 15 and 15 Plus are the last iPhones to feature 6 GB of RAM and the mute switch, as they do not feature the Action Button, unlike the 15 Pro series and subsequent models. The iPhone 15 and 15 Plus were discontinued on September 9, 2025, following the announcement of the iPhone 17.
The main cons of the iPhone 15 include its 60Hz display (lacking ProMotion), slow USB 2.0 data speeds on the USB-C port, no dedicated optical telephoto lens, slower charging speeds compared to some Androids, and a lack of Apple Intelligence support (reserved for Pro models). It also still requires a separate charger and has a less advanced chip than the Pro models, potentially limiting its long-term cutting-edge software support.
The widespread complaints about the iPhone 15 Pro Max overheating point to software bugs in iOS 17. Besides that, your device might feel warmer during the first few days after setup or restoration due to increased background activity. Other possible reasons include battery-draining or outdated third-party apps.
The iPhone 15 series brought major changes like the Dynamic Island across all models (replacing the notch), a shift to USB-C charging, significantly upgraded 48MP Main Cameras for better photos and a 2x optical-quality zoom, and new contoured edges with matte glass for a more comfortable feel, plus the Pro models introduced a customizable Action Button and titanium frames.
Messages automatically uses the following screen effects for specific text strings:
*3001#12345#* on an iPhone activates the hidden Field Test Mode, a diagnostic tool for network engineers and power users to see detailed cellular data like signal strength (dBm), cell tower info, and network quality, accessible by dialing the code in the Phone app and pressing call, often after turning off Wi-Fi for accurate cellular readings.
