JoiPlay Game Closes in the Background? Stop Android Killing Your Game

You pause to answer one quick message, switch back to your game, and JoiPlay has restarted from the title screen, taking all your unsaved progress with it. If your JoiPlay game closes in the background like this, Android is almost certainly killing the app to save battery or free up memory, not a fault in the game itself. The good news is that a few settings can stop most of it: set JoiPlay to Unrestricted battery use, lock it in Recents, and keep it out of device care cleaning. This guide explains why it happens and walks through each fix step by step.

Why Android Kills JoiPlay in the Background

Android is designed to protect your battery and keep your phone feeling fast, even if that means closing apps you still want open. When you leave an app, Android may keep it in memory for a quick return, pause it, or close it completely if the system needs the resources. JoiPlay is an easy target, because a running game can use a fair amount of memory.

Battery savers are doing what they were told to do

Most phones ship with battery optimization turned on for almost every app. That system limits or kills apps that look idle, even if you only stepped away for a minute. Some brands add their own extra layer on top of standard Android, which is why the same game can survive a switch on one phone and die instantly on another. Setting JoiPlay to Unrestricted tells Android to leave this app alone.

RAM pressure makes the problem worse

Battery settings are only half the story. RAM is your phone’s short term memory for open apps, and if you switch to a heavy app, like the camera or a browser with many tabs, your phone may need that memory right away. Android then closes background apps to make room, starting with large ones like games.

That is why the problem feels random: a light switch may be fine, while the camera kills the game every time. The performance tips in JoiPlay Lag Fix can also help stability. Signs that Android, not the game, is the problem:

• ✅ Game restarts from the title screen after a short switch away
• ✅ Problem gets worse when you open the camera or a browser
• ✅ Other apps also reload when you return to them
• ❌ Game crashes at the same point while you are actively playing
• ❌ Game shows an error message before it closes

If JoiPlay closes while you are actively playing, work through JoiPlay Not Working instead.

Step 1: Set JoiPlay Battery Usage to Unrestricted

This is the most important fix, so do it first. By default, JoiPlay is usually set to Optimized, which lets Android manage its background activity. Changing it to Unrestricted tells Android this app is allowed to use battery in the background without being shut down to save power.

Menu names vary between brands, so follow the idea rather than the exact words. Look for Battery or App battery usage inside the JoiPlay app info page. If you see Unrestricted, Optimized, and Restricted, you are in the right place.

How to set battery usage to Unrestricted

1. Open your phone Settings.
2. Tap Apps, then find and tap JoiPlay.
3. Tap Battery or App battery usage.
4. Select Unrestricted.
5. Repeat for any JoiPlay plugins you use, if they appear as separate apps.
6. Restart your phone once so the new setting settles in.

Do the plugins as well, because a game can fail if Android kills a plugin it needs. Do not set every app to Unrestricted though, as that hurts battery life for no benefit.

Step 2: Lock JoiPlay in the Recents Screen

Locking an app in Recents tells your phone not to clear it when you tap a close all button or when the system does a quick tidy up. It is a simple layer of protection that works alongside the battery setting. On many phones a small padlock icon shows on the app card once it is locked. Locking does not beat severe RAM pressure alone, but it stops accidental clear all actions wiping your session. Combined with Unrestricted, it covers most everyday switches.

How to lock JoiPlay in Recents

1. Open JoiPlay and launch any game for a moment.
2. Open the Recents screen, which shows recent apps as cards.
3. Find the JoiPlay card.
4. Tap the app icon or the three dot menu on that card.
5. Tap Lock, Lock this app, or the padlock icon if you see one.
6. Check that a lock symbol now shows on the card.

If there is no lock option, try long pressing the JoiPlay card in Recents. If your device has none at all, skip this step, as the battery settings matter more.

Step 3: Exclude JoiPlay From Device Care or Memory Cleaning

Many phones have a built in cleaner with names like Device care, Memory cleaner, or Phone manager. These tools promise to speed up your phone by closing background apps and clearing memory. If JoiPlay is on their list, they can kill your game even after you fixed the battery setting.

Some cleaners run on a schedule or when you tap optimize, closing everything in the background at once. Excluding JoiPlay stops the cleaner treating your game like junk.

How to exclude JoiPlay from cleaning

1. Open Settings and look for Battery, Device care, or a cleaner section.
2. Open the cleaner or optimization tool your phone provides.
3. Look for an exclusion list, protected apps list, or similar.
4. Add JoiPlay to the protected or excluded list.
5. Add any JoiPlay plugins you use to the same list.
6. Avoid tapping optimize or clean all while a game is paused.

If your cleaner has no exclusion list, turn off scheduled and automatic cleaning instead. You can still clean manually when no game is running.

Step 4: Turn Off Put Unused Apps to Sleep Style Options for JoiPlay

Some phones add another layer that puts apps to sleep if you have not opened them for a while, or if they sit in the background too long. Wording differs, so you may see phrases about sleeping apps or background usage limits. The goal is to make sure JoiPlay is not on any sleep list. This can override your Unrestricted choice, so checking both places is what makes the fix stick.

How to check the sleeping apps settings

1. Open Settings and look for Battery or Background usage limits.
2. Look for a section about sleeping apps or unused apps.
3. Open the sleeping and deep sleeping lists, if your phone has both.
4. Remove JoiPlay from those lists if it appears there.
5. Add JoiPlay to a Never sleeping or protected list if one exists.
6. Repeat for your JoiPlay plugins.

Also check that Battery Saver is not running while you play, as it tightens limits for every app. Turn it off during sessions and back on later.

What Each Setting Actually Stops

Each fix blocks a different way Android can kill your game, so doing only one helps but doing all of them closes the gaps. Use this table as a quick reference while you work through the steps. If your game still restarts after all five, the cause is more likely raw RAM pressure than a setting.

| Setting | What it stops | | Unrestricted battery usage | Android closing JoiPlay to save battery | | Locking JoiPlay in Recents | Clear all actions and quick tidy ups removing the game | | Excluding JoiPlay from device care | Cleaner tools closing the game during an optimize run | | Removing JoiPlay from sleeping apps lists | The system putting JoiPlay to sleep in the background | | Turning off Battery Saver while playing | Extra strict background limits applied to every app |

Habits That Protect Your Progress

Settings reduce the risk, but habits remove most of the pain when Android still wins. JoiPlay saves are written to the game folder when you save in game, and there is no automatic cloud sync to rescue you. If Android kills the app before you save, everything since your last save is simply gone.

Saving decides whether a background close costs you thirty seconds or thirty minutes.

Save before you switch, every time

1. Open the in game menu before you leave JoiPlay.
2. Save to a slot you rotate, so one bad save does not replace your only good one.
3. Wait until the save finishes and you are back in the game.
4. Only then switch to your other app.

The JoiPlay Save File Transfer Guide shows how to move saves safely if you change phones or reinstall.

Keep sessions and switches light

• ✅ Close heavy apps, like browsers and video apps, before a long session
• ✅ Keep switches short and avoid opening the camera mid session if your phone struggles
• ✅ Play in shorter sessions on low RAM phones, saving at natural breaks
• ✅ Keep Battery Saver off during boss fights or long story scenes
• ❌ Do not leave a game paused in the background for hours and expect it to survive
• ❌ Do not tap optimize or clean buttons while a game is paused

Keeping the game alive also helps controller users, since a restart means reconnecting. See the JoiPlay Controller Setup Guide for pairing help.

Quick Checklist to Stop Background Kills

Run through this checklist once before your next gaming session. Recheck these settings after a major phone update, as updates can sometimes reset your battery preferences.

• Make sure JoiPlay’s battery usage is set to Unrestricted so the system is less likely to stop it running in the background.
• Set the battery usage of all JoiPlay plugins to Unrestricted as well.
• Lock JoiPlay in the Recents screen, if your phone supports this feature, to help prevent the system from closing it.
• Exclude JoiPlay from Device Care, memory cleaners, or automatic optimization tools that may close background apps.
• Remove JoiPlay from the Sleeping Apps or Deep Sleeping Apps lists to prevent the phone from restricting its background activity.
• Turn off Battery Saver while playing to reduce the risk of background restrictions.
• Save your game before switching to another app to avoid losing progress if JoiPlay closes unexpectedly.

Conclusion

When JoiPlay closes in the background, Android is usually just following its battery and memory rules a little too eagerly. Setting JoiPlay to Unrestricted, locking it in Recents, and keeping it out of cleaner and sleeping apps lists tells your phone, in every language it understands, that this app matters. No single setting is perfect, but together they stop the great majority of background kills. Pair those settings with one simple habit, saving before you switch apps, and a restart stops being a disaster. You may still lose a game on a low memory phone during a heavy switch, but it will cost you minutes of progress at most, not a whole session.
