To make a phone last longer during puzzle games, first lower screen brightness to a comfortable level and use Wi-Fi instead of cellular data when the game needs an internet connection. If that is not enough, try your phone’s battery-saving mode, reduce game or display performance settings where available, and check battery usage if the drain seems unusual. The best settings depend on your phone, display, operating-system version, and game.
Start with the changes that affect most gaming sessions
Lower brightness without making the game hard to see
A bright display can use substantial energy. Dim the screen until it remains comfortable to read, and consider Auto-Brightness if your phone’s screen is often brighter than the room requires. Apple recommends both approaches, but the amount of power saved depends on the screen and viewing conditions. Apple’s battery guidance explains the factors that affect iPhone and iPad battery use.

Prefer Wi-Fi when the game needs an internet connection
When Wi-Fi is available, use it instead of mobile data for online play. Apple and Google both recommend Wi-Fi as a lower-power option for data access. Cellular reception matters too: a weak signal can increase battery use. Airplane mode is only appropriate if you do not need mobile service and the game works offline; it may prevent online features, ads, account syncing, or other network functions from working.
Pause when you step away
Pause or exit a game when you stop playing, and let the screen lock normally. A game that keeps the display awake while idle can continue using power even when nobody is interacting with it. Apple’s developer documentation describes this mechanism, though its example is archived guidance rather than evidence about how a particular current game behaves. Apple’s archived developer guidance explains why an awake display can drain a battery.

Use battery-saving modes when you need more runtime
iPhone and iPad
On current Apple support guidance, open Settings > Battery > Power Mode and turn on Low Power Mode; it may also be available in Control Center. The mode reduces or disables selected features, including Mail fetch, Hey Siri, Background App Refresh, and some visual effects. If you want to limit background updating separately, look under Settings > General > Background App Refresh. Apple notes that labels and availability can vary by operating-system release. See Apple’s current battery support page for its guidance.
Android phones
Look under Settings > Battery for Battery Saver or a similarly named mode; manufacturers may place it elsewhere or use a different label. Google says Battery Saver can limit background activity and may enable Dark theme. It can also delay some visual effects, features, network connections, or apps, so check whether notifications or online game functions still behave as you expect. Google’s Android battery guidance describes these trade-offs.
Battery Saver is a useful option when you need the phone to last, but it is not a guaranteed way to preserve every game feature. Google’s general guidance lists graphics-heavy and highly interactive games among activities that can use battery; that is not a measurement of puzzle games specifically.

Check game and display performance settings
Reduce frame rate or graphics only if the controls exist
Some phones and games offer graphics quality, frame-rate, or display refresh-rate controls. If your device lets you match the display refresh rate to the game’s target frame rate, try that setting: Android Developers says a refresh rate above the game’s target can use more power without adding a benefit for that game. Lower frame rates may make movement look less smooth, so choose a setting that remains comfortable to play. These controls are not available on every phone or in every game. Android Developers’ power-efficiency guidance covers frame rates, heat, and game performance.
Look for a battery-oriented Game Mode
Some Android devices provide a Game Mode or game dashboard that can trade performance for battery life. Availability and behavior depend on the manufacturer, device, and whether the game supports the relevant settings. If you find a battery-focused option, try it and check whether the game still feels responsive; do not assume every Android phone has the same control.
Keep the phone cool
Heat reduces power efficiency, and high CPU or GPU use can cause a device to throttle performance. If the phone becomes hot during play, lower the game’s workload if possible and take a break rather than trying to force higher performance. A hot phone is not proof that a specific puzzle game is poorly optimized: temperature can also depend on the device, surroundings, brightness, and other activity.

Does dark mode save battery during puzzle games?
It can, particularly when the phone has an OLED display and the game uses genuinely dark artwork. On OLED screens, darker pixels require less power than lighter ones. Apple engineer Vaibhav Gautam made this point in Apple Developer’s WWDC22 session, “Power down: Improve battery consumption.”
What’s actually slowing this PC down?
Pick the symptom - the matching free tool is one click away.
In a demonstration of a particular app on OLED, Apple presented an estimate of up to 70% display-power savings for its darker presentation, with greater savings at higher brightness. That figure applies to the example’s display power—not to total phone battery drain, all apps, or puzzle games in general. An LCD screen or a game with bright, fixed artwork may see little or no benefit. Use a game’s dark theme if it is available and you prefer its appearance, but do not expect a specific increase in play time.

Check app-level battery use
If drain remains unusually high, inspect which apps are using power rather than relying on guesswork. On iPhone or iPad, Apple directs users to Settings > Battery to see battery use by app. Android settings also provide battery-use information, though the exact path and labels vary by manufacturer. A game may use more power because it is open for a long time, animates constantly, displays ads, or uses network access; no single factor applies to every title.

Allow for activity after an iOS update
After an iOS update, background update tasks can temporarily affect battery life and thermal performance. Apple advises checking again after a few days. If the change began immediately after updating, avoid treating the first day’s battery behavior as proof that the game or battery has permanently worsened. Apple’s support guidance covers post-update battery behavior.
Check battery health before considering service
If battery life is poor across multiple apps, review Battery Health on an iPhone or iPad. Apple says to consider battery service if the Battery Health screen reports Service. Replacing a battery is a device-condition decision, not the first step for a phone that drains only during a particular game.
