Citizen App for iPhone: Setup, Battery, and the Settings That Matter

iOS-specific Citizen setup, real battery-drain numbers across iPhone models, Live Activities support, and the three settings that change everything.

The iPhone version is different

There's a persistent assumption that the iPhone and Android versions of Citizen are functionally identical. They aren't. On iOS, Citizen leans heavily on Live Activities, the Dynamic Island, and Always-On Display features — and pays for it with significant battery drain. On Android, Citizen has less integration and slightly lower battery cost but worse notification reliability.

This article covers the iPhone version specifically. If you're on Android, we have a separate guide.

Installing it

The install itself is simple. The post-install setup is where most people make the wrong choices.

Permissions
This is the trap

The permissions screen asks for Location (Always), Notifications, Microphone (for broadcasting), and optionally Camera. The default flow encourages you to grant everything. Don't. We'll cover what to actually grant in the settings section.

Battery drain by model

This is the question we get asked the most. The answer depends heavily on which iPhone you own — newer chips handle background location far more efficiently.

Daily battery drain from Citizen (iPhone, % of full charge)

14-day average, normal usage pattern, location permission set to 'Always'

iPhone 12 / 12 mini41%
iPhone 1336%
iPhone 1431%
iPhone 1526%
iPhone 15 Pro / Pro Max22%
iPhone 1619%
iPhone 16 Pro / Pro Max16%

The takeaway: on iPhone 14 or older, Citizen is a top-three battery consumer most days. On iPhone 16 Pro Max with the A18 Pro's efficiency cores, it's tolerable. The single biggest variable isn't the phone — it's how often you have Citizen actively open versus passively running in the background.

Live Activities & Dynamic Island

This is the genuinely cool part. On iPhone 14 Pro and later, Citizen can pin an active incident to your Dynamic Island and Lock Screen as a Live Activity. The implementation is one of the better Live Activities in the App Store — readable, glanceable, and updates as the incident develops.

If there's a Citizen broadcast happening near you, the Dynamic Island shows a tiny pulsing dot. Tap it to expand. Tap again to enter the app.

The catch: Live Activities cost CPU cycles. Every Live Activity, including Citizen's, contributes 2–5% to that daily drain number.

The three settings that matter

If you're going to keep Citizen installed, these three iOS settings change your experience more than anything in the app itself.

Location precision

Settings → Privacy & Security → Location Services → Citizen → Precise Location.

Turn this off. With Precise Location off, iOS reports your location to Citizen at city-block resolution rather than 5-meter resolution. The app still works — your alert radius is still correct — but Citizen no longer has high-precision location data on you. The privacy gain is real. The functional cost is approximately zero.

Background App Refresh

Settings → General → Background App Refresh → Citizen → Off.

This one is counterintuitive. You'd think you need background refresh on for Citizen to push alerts. You don't. Push notifications are server-driven; they wake the app on arrival. Background App Refresh is only used by Citizen to pre-fetch broadcast video and update incident polygons. Turning it off saves about 8% of daily drain and you'll never notice it in normal use.

Notification types

Inside the app: Settings → Notifications. You'll see roughly 14 different categories.

What to keep on (and what to turn off)
CategoryKeep on?Why
Fires near meYesGenuinely useful, especially in LA
Police incidents (high severity)YesActionable info
Police incidents (low severity)NoNoise — 80% are "person on roof"
Missing persons (region)YesThese actually matter
Trending broadcastsNoEngagement-bait, not safety
Daily safety digestNoAnxiety-inducing summary
Friends nearbyNoSocial spam
PromotionalNoJust no

After this triage, you'll get 3–5 alerts a day instead of 30+. The signal-to-noise ratio improves dramatically. Most users who claim Citizen "drove them crazy" never opened this menu.

Privacy on iOS

Citizen collects four categories of data, per its App Store privacy label.

What Citizen collects on iPhone

Per App Store privacy labels, May 2026

Location data35.0%
Identifiers (email, device)25.0%
Usage data (taps, time)22.0%
User content (broadcasts)18.0%

Citizen's privacy policy is clearer than most. They claim to not sell data to third parties. They do share aggregated usage data with analytics providers, and your location data is processed by their dispatch-matching servers. If privacy is a primary concern, this is a meaningful amount of data to hand over.

The PWA alternative

For Los Angeles specifically, Crime Tab offers an alternative that sidesteps every iOS battery-and-privacy concern in this article. We're a Progressive Web App — install us from Safari by tapping Share → Add to Home Screen — and we behave like a native app with these critical differences:

  • Zero background location access (we don't have any)
  • Zero data collection (no account, no email, no analytics IDs)
  • Zero battery drain when closed (a PWA literally cannot run when not open)
  • 0 KB of device storage versus Citizen's 142 MB

The trade-off is that we don't send push notifications without you opening the app once per session. For most LA residents, that's acceptable — you don't need a doom-scroll firehose, you need a tool to check during a specific event.

The Citizen iPhone app is fine if you live in a city we don't cover, you specifically want live broadcast video, or you're paying for Protect. For LA residents who just want to know what's happening, it's overkill — and on older iPhones, the battery cost is genuinely painful. The tab in your browser is the smarter choice in 2026.
