Do casino apps drain battery? Faster than reading an email, slower than most people fear. A casino app uses power like any other game: the bright screen, animated reels and, above all, live dealer video streams do most of the work. Unusual drain while the app is closed usually points to location access or background activity, which you can switch off in Settings.
Screen time, brightness and live video streams use far more power than slots or menus.
Drain while the app is closed usually comes from location access or background refresh.
iPhone and Android both show per-app battery use, so you can see whether the casino app is really to blame.
A battery dropping fast is also a useful clue that a session has run longer than planned.

Do casino apps drain battery more than other apps?
There’s nothing special about casino software that eats power. Slots inside an app are usually HTML5 games, the same technology as many browser games, and they run on your phone’s graphics chip while the result itself comes from a server. Menus, the cashier and account pages are light work.
What makes a casino session costly is the same as for any game: the screen stays on at full brightness, animations run continuously, and the phone keeps a data connection open. Live casino adds a constant video stream on top. So yes, a long session will take a noticeable chunk out of your battery, but a well-built casino app shouldn’t keep draining it once you’ve closed it.
If your phone loses charge overnight and the casino app tops the battery list, that’s a different problem, and almost always a setting you can change.

Data and battery go hand in hand: whatever downloads the most usually burns the most power too. Our casino app data usage guide covers the data side, including why live casino apps are the heaviest by far.
How to check a casino app’s battery use on iPhone
Open Settings and tap Battery.
Scroll to the chart and choose Last 24 Hours or Last 10 Days.
Look down the list of apps for the casino app and the percentage beside it.
Tap the app (or Show Activity) to split its usage into on-screen time and background time.
If background time is high compared with the time you actually played, change the location and background settings described below.
Settings › Battery › Battery Health also shows your battery’s maximum capacity. An older battery drains quickly with any demanding app, which is often the real cause on phones a few years old.
How to check a casino app’s battery use on Android
Open Settings and tap Battery (on Samsung, Battery and device care, then Battery).
Tap Battery usage or View details since last full charge.
Find the casino app in the list and tap it.
Compare foreground (screen on) and background use.
Under the app’s battery options, choose Optimised or Restricted to limit background activity.
Menu names differ between makers, so if you can’t find these options, search for “battery usage” in the Settings search bar. Owners of budget Android phones tend to notice drain sooner, as smaller batteries and less efficient chips feel heavy games more.
Location access: the hidden battery drain
Some casino apps request your device location, partly for licensing reasons. Location used only while the app is open costs little. Location allowed all the time can keep waking the phone up after you’ve stopped playing.
Store listings sometimes say so directly. PlayOJO’s App Store listing, for example, states that the app may use your location even when it isn’t open, which can reduce battery life. Ladbrokes’ iOS privacy label lists precise location and Coral’s lists coarse location. Our page on whether casino apps track your location explains why apps ask.
iPhone: Settings › Privacy & Security › Location Services › [casino app] › choose While Using the App, and consider turning off Precise Location if the app still works without it.
Android: Settings › Location › App location permissions › [casino app] › Allow only while using the app.
If an app needs location to confirm you’re in Great Britain, setting it to Never may stop games loading. While Using is the balance between battery and access.
Settings that cut casino app battery drain
Lower screen brightness or turn on auto-brightness; the display is the single largest power user during play.
Switch off Background App Refresh for the casino app (iPhone: Settings › General › Background App Refresh) or restrict background battery use on Android.
Mute marketing push notifications you don’t need; our guide to casino app notifications explains which ones are worth keeping.
Turn off in-app sound and haptics if the app offers it. Casumo’s iOS app, for instance, lists a haptic feedback toggle.
Use Wi‑Fi rather than weak 4G or 5G signal when you can.
Close the app fully when you finish rather than leaving a slot or live table open in the background.
Turn on Low Power Mode (iPhone) or Battery Saver (Android) for long journeys; games still run, with some effects reduced.
Live dealer games: the heaviest battery users
A live table is a video call you can bet on. The phone decodes a high-quality stream for the whole session, the screen stays on and the data connection never rests. Many live games let you lower the stream quality from a settings or video icon on the table, which cuts both data and power. Landscape mode on a phone usually gives a bigger picture but uses the same stream, so it doesn’t change battery use much.
On 5G, a strong signal is efficient, but patchy 5G that keeps switching to 4G costs extra power; our 5G casino apps page explains why.
Phone getting hot while playing? What to do
Warmth during a long session is normal. A phone that’s hot to hold is not, and both iPhone and Android will throttle performance to protect the battery, which can make games stutter or freeze.
Take the phone out of a thick case and away from direct sun.
Avoid playing while fast-charging; heat from charging and gaming adds up.
Close other apps running in the background, particularly navigation or video.
If it keeps happening after an update, the app may have a bug; update again when a fix arrives, or reinstall.
Playing the same game in an app or in Safari or Chrome uses broadly similar power, because the game itself is the same. Differences come from the extras. An app may run background tasks or location checks; a browser may keep other tabs active and can’t always be restricted as precisely. If you rarely play, the browser avoids an app sitting on your phone with permissions. If you play often, a properly configured app is just as frugal. See casino app or mobile site for the wider comparison.
When the battery tells you something about your session
If your battery has dropped by a large chunk since you started playing, that’s a fair sign the session has run longer than you thought. Casino apps in the UK show reality checks for the same reason; why casino apps show reality checks explains how to set their timing. Gambling is entertainment with a cost, so a natural stopping point, such as a low battery warning, is a good moment to take a break rather than reach for the charger.

Frequently asked questions
Why does my casino app drain battery when I’m not using it?
Usually because it has location access set to Always, Background App Refresh switched on or frequent notifications. Some listings say this outright: PlayOJO’s App Store listing notes the app may use location when it isn’t open, which can reduce battery life. Set location to While Using the App, turn off background refresh for the app and mute notifications you don’t need. Then check the battery screen again after a day. Our page on whether casino apps track your location explains the location settings.
Do live casino games use more battery than slots?
Yes, considerably. A live table streams continuous video, so your phone decodes a stream, keeps the screen on and holds a steady data connection for the whole session. Slots only animate locally and exchange small amounts of data with the server. Lowering the stream quality from the table’s settings icon, playing on Wi‑Fi and reducing brightness all help. Live games also use the most data, as our casino app data usage guide explains in detail.
Is it bad to play casino apps while charging?
It isn’t dangerous on a phone in good condition, but it adds heat, which isn’t good for long-term battery health. Fast charging and a demanding game together can make a phone warm enough to slow down. If you need to charge, a standard charger, no thick case and a cool surface help. Charging to keep a session going is also worth a second thought from a time point of view. Our reality checks page explains session reminders.
Does Low Power Mode affect casino apps?
Games still work in Low Power Mode on iPhone and Battery Saver on Android, but the phone may reduce animation smoothness, background activity and screen brightness. Live streams can drop to lower quality if the connection is also slowed. None of that changes game results, which are decided on the casino’s server. If a game feels sluggish in power-saving mode, it’s the phone holding back, not the game. The iPhone casino apps guide covers other iOS settings that affect performance.
Which uses more battery, a casino app or the mobile site?
Broadly the same for the games themselves, since the same game code runs in both. An app may add background activity such as location checks or notifications, while a browser may keep other tabs alive. Once background settings are configured, the difference is small. Choose based on convenience and features such as biometric login rather than battery. Our casino app or mobile site comparison sets out the real trade-offs between the two.
Why does my phone get hot when I play slots?
Animated slots keep the graphics chip and screen busy, and heat builds faster at high brightness, on weak signal, in a thick case or while charging. Some warmth is normal. If the phone becomes hot to touch, it will slow itself down to protect the battery, and games may stutter. Let it cool, remove the case and close background apps. Persistent overheating after an update may be an app bug; see casino app keeps crashing for fixes.
Do casino app notifications drain the battery?
Each notification uses very little, but frequent ones add up, especially overnight, because they wake the screen and the radio. Promotional messages are the easiest to cut without losing anything useful. Keep account and security alerts, and mute marketing in the app’s settings or your phone’s notification settings. Turning off marketing alerts also means fewer prompts to play when you hadn’t planned to. Our casino app notifications guide explains what to allow and what to mute.
Will deleting and reinstalling a casino app fix battery drain?
Sometimes, if the drain started after an update or a corrupted install. Reinstalling clears the app’s stored data and resets its permissions, so you’ll be asked again about location and notifications; choose While Using and only the alerts you want. Your account, balance and limits are unaffected because they live on the casino’s servers. If drain returns straight away, report it to support. Our app cache entry explains what reinstalling clears.
Do casino apps use more battery on 5G?
They can. A strong, stable 5G signal is efficient, but patchy 5G that keeps switching back to 4G makes the phone’s radio work harder, which costs power. Live casino streams on a weak signal are the worst case. If your battery is low, switching to Wi‑Fi or setting your phone to prefer 4G can help without affecting the game. Our 5G casino apps page looks at signal, speed and battery together.
