You switch from your browser to answer a text, come back thirty seconds later, and the page reloads from the top. You reopen a game and it boots from the splash screen instead of where you left off. A half-written form is gone. If your phone keeps reloading apps and tabs, it is not broken, and it is almost never a storage problem. The real culprit is RAM, and the way modern phones aggressively manage it.
Once you understand the difference between RAM and storage, the fix list gets shorter and more effective. Spoiler: clearing your cache is not on it.
Your phone reloads apps and tabs because their live state lives in RAM (working memory), not storage. When RAM fills up, the operating system evicts backgrounded apps and discards browser tabs to free space, so reopening them forces a fresh reload from storage or the network. Clearing storage or cache does not add RAM, so it rarely helps. Closing fewer apps, keeping fewer tabs open, and turning off aggressive battery restrictions are what actually reduce reloads.
RAM vs storage: two completely different jobs
Storage (the 128GB, 256GB, or 512GB figure on the box) holds your files, photos, and installed apps permanently, even when the phone is off. RAM is fast, volatile working memory that holds what is running right now: the app you are using, its current screen, your scroll position, and the tabs open in your browser. When you switch away from an app, that live state stays parked in RAM so you can resume instantly.
The problem is that RAM is small and finite. Current flagships like the Galaxy S25 and iPhone 17 Pro ship with 12GB, but mid-range and budget phones often have 6GB or less, and the operating system, system services, and on-device AI features all reserve a chunk before your apps get any. When RAM runs out, something has to give.
Why apps reload: eviction and memory pressure
When free RAM gets low, both Android and iOS reach a state called memory pressure. The system first asks apps to release memory, then starts terminating backgrounded processes to reclaim it. Android uses a Low Memory Killer Daemon (LMKD) that scores running processes; background apps get killed first, system processes last. iOS does the same thing through a kernel mechanism called Jetsam, which jettisons suspended apps under pressure.
Here is the key part: a suspended app sitting in RAM resumes almost instantly because it is just a read from memory. But once the OS evicts it, that live state is gone. Reopening means a cold start: the phone has to read the app from storage, rebuild the screen, and reconnect to the network. That is the reload you see, and it is why the app starts from the beginning instead of where you left it.
Why some Android phones are worse than others
Stock Android and iOS are reasonably good at keeping recently used apps alive. Some Android skins are not. Skins like Samsung’s One UI and Xiaomi’s HyperOS (formerly MIUI) layer their own aggressive battery and memory management on top of Android, and they can kill backgrounded apps far sooner than the underlying OS would, even when RAM is available. The community site dontkillmyapp.com tracks this, and brands including Xiaomi, OnePlus, Huawei, and Samsung have all ranked among the most aggressive offenders.
The upside is that these are settings, not hardware limits. You can usually exempt specific apps from being killed. The fix differs by brand, but the idea is the same.
Do this
Lock or pin important apps in the recent-apps view, set their battery usage to “Unrestricted,” and disable any “memory optimization” or “clear background apps” toggle in your skin’s settings. This tells the system to leave them alone.
Not that
Do not swipe-close every app to “free memory,” and skip third-party RAM cleaner apps. Killing a suspended app guarantees a slow cold reload next time, wastes CPU and battery, and the cleaner just gets re-killed by the OS anyway.
Browser tabs reload for the same reason
A reloading tab is the same story with a browser-shaped twist. To save memory, browsers discard inactive tabs: the title and favicon stay in the tab strip, but the page itself is unloaded from RAM. Revisit it and the browser reloads the page from the network. On desktop, Chrome’s Memory Saver does this once a tab has been idle, and recent versions also use a model that predicts which tabs you are unlikely to return to and drops them sooner. On phones the behavior is more aggressive because mobile RAM and thermal budgets are tighter, so background tabs get dropped quickly. The more tabs you keep open and the heavier each page (video, lots of images, complex web apps), the sooner the browser starts discarding them.
Why clearing storage and cache will not fix it
This is the most common wrong turn. Clearing an app’s cache or freeing up storage operates entirely on storage, not RAM. Deleting cached files does not give the OS more working memory, so it does nothing to stop eviction. Worse, it can be counterproductive: clearing data can log you out, and clearing cache means the next launch is slower because the app must rebuild those files. If your phone is reloading apps, freeing storage is treating the wrong organ. (Genuinely low on space? Our guide to free up Android storage without deleting covers that, but it is a separate problem.)
RAM vs storage at a glance
| Aspect | RAM | Storage |
|---|---|---|
| What it holds | Live state of running apps and tabs | Files, photos, installed apps |
| Keeps data when off? | No, it is volatile | Yes, permanent |
| Typical size | 6-16GB | 128-512GB+ |
| Causes reloads when full? | Yes, apps and tabs get evicted | No |
| Does clearing cache help? | No, cache lives in storage | Frees space, not reloads |
What actually reduces reloads
Before the OS kills anything, it tries to make RAM stretch. Android compresses idle memory into zRAM (a compressed swap area held in RAM) and iOS uses memory compression too, squeezing inactive pages smaller so more apps can stay resident. That buys headroom, but it is not infinite. To reduce reloads in practice: keep fewer apps and browser tabs open at once; on One UI, HyperOS, or a similar skin, set your critical apps to unrestricted battery use and pin them in recents; and stop manually closing apps you will reopen soon. If reloads are constant and severe on an older phone, the honest answer is that 4-6GB of RAM is simply tight for today’s apps, and the long-term fix is more memory.

Frequently asked questions
Does adding more storage stop my apps from reloading?
No. Reloading is caused by full RAM (working memory), and storage is a separate component that holds files permanently. Buying a phone with more storage, or freeing up storage space, does nothing for RAM. Only more RAM, or fewer apps and tabs running at once, reduces reloads.
Should I close background apps to free up memory?
Generally no. A suspended background app uses little power and resumes instantly, while a closed one must cold-start and reload from scratch, which costs more CPU and battery. Modern Android and iOS manage memory better than manual swiping does, so closing apps usually makes reloads more frequent, not less.
Why does my browser reload a tab the moment I switch back to it?
To save memory, browsers discard inactive tabs: the tab stays visible in the strip but the page is unloaded from RAM, so revisiting it triggers a reload from the network. Phones do this aggressively because mobile memory is limited. Keeping fewer tabs open and closing heavy, media-rich pages reduces how often it happens.
My Samsung or Xiaomi phone kills apps constantly. Is that normal?
It is common. One UI, HyperOS, and similar skins add aggressive battery and memory management that can close backgrounded apps even when RAM is free. You can usually fix it by setting the app’s battery usage to unrestricted, disabling memory optimization toggles, and pinning the app in the recent-apps view. The site dontkillmyapp.com has brand-specific steps.
Does clearing the cache help with apps reloading?
No. Cache lives in storage, not RAM, so clearing it does not give the system more working memory to keep apps alive. It can even make the next app launch slower because cached files have to be rebuilt, and clearing app data can log you out. Clearing cache is for freeing storage space, not for fixing reloads.
