Best Offline Games and Apps for Android: Get Your Phone Ready for a UK Power Cut
1. The short answer
The UK government says that in a power cut "your home internet won't work" and "your mobile phone might stop working if your local mast is in the affected area." So for an Android phone, the useful games and apps are the ones that need no connection at all: offline map areas you've downloaded, and offline-first apps — the games Captain Star, Zero G and Down the Drone, plus Lookout and 70 BPM. Install them now, then switch on aeroplane mode and check each one opens.

2. What the UK government says
From Power cuts on the government's Be Ready site:
- Most power cuts are short and local, but "more widespread and longer outages can happen" and "could potentially last several days."
- "You would lose internet connection and possibly mobile signal during a power cut."
- Use a battery or wind-up torch: "You probably won't want to use the torch on your mobile phone as this will drain its batteries more quickly."
- In a national energy shortage, rota cuts could disconnect each area "for around three hours at a time" — find your load block letter at powercut105.com.
And the Be Ready checklist lists a "charged power bank" to charge phones or compatible medical devices.

4. A three-hour rota cut vs a multi-day outage
Three hours (a rota cut or short local fault): one or two phones, a game or two, a torch, and the fridge door kept shut. The government says fridges and freezers "stay cold for several hours" if you keep them closed.
Several days (storm damage): now the phone is your lifeline. Ration it. Games become short treats, the power bank is for calls and checking in, and the battery or wind-up radio — on the government's list — becomes your news source. The government also says to keep 3 days of bottled water (3 litres per person per day) and food that doesn't need cooking.
5. Android battery settings for a power cut
- Turn on Battery Saver (or Extreme/Ultra saving modes on some phones) as soon as the lights go.
- Lower brightness and switch on dark mode.
- Turn off Wi-Fi, Bluetooth and location when you don't need them — scanning for a dead network wastes power.
- Use a real torch, as the government advises, not the phone flashlight.
- Keep a charged power bank and top it up every six months when you check your kit (the government suggests a six-month check).
- Unplug chargers until power returns: the government advises unplugging the TV and PC in case of a surge.
6. Offline apps for a power cut
Every app and game below works fully offline, with nothing sent to a server.
- Captain Star — App Store
- Zero G (formerly Astro Belt) — App Store
- Down the Drone — App Store
- Lookout — App Store: camera + GPS with near-360° capture, stored on your phone. Note conditions for your own records, or film the family.
- 70 BPM — App Store: calm breathing and heart-rate check-ins for anxious moments in the dark. Not a medical device; it does not diagnose or treat anything. In an emergency, call 999 or 112.
7. Long winter evenings: keeping everyone warm and calm
The government's advice is to keep warm "using blankets and layered clothing," close doors of unused rooms and draw curtains. So gather everyone in one room and make it an event:
- Card games and board games by torchlight.
- A family "power cut film" shot on Lookout — torchlight storytelling, a living-room weather report.
- Short game turns on one phone, passed round, while the others charge.
- A slow-breathing wind-down with 70 BPM before bed.
8. Older relatives and neighbours
The government asks people to check in on neighbours, especially if the power goes out, and says older adults, babies and people with long-term health problems are most at risk from the cold. If you're visiting an older relative, set up a simple offline card game and offline maps on their phone, and check whether they're eligible for the Priority Services Register (thepsr.co.uk). If anyone relies on a personal alarm or a diabetes sensor, the government says to ask the provider how it works in a power cut — that device's power comes before any game.
