Skip the “magic cleaner” apps. Most of them do nothing useful, some track you, a few make things worse.

What works depends on your phone.

  1. If you use iPhone
    Apple already handles RAM and most system cleanup. Extra “cleaner” apps often waste storage.

Do this instead:
• Settings → General → iPhone Storage → sort by size, delete big unused apps.
• In each heavy app, clear caches where possible.
• Photos → remove duplicates, long videos, screen recordings.
• Offload unused apps in iPhone Storage.
• Restart the phone once in a while.

If you still want an app, the ones @mikeappsreviewer mentioned from that AI cleaner list are fine to explore, but treat them as helpers for finding large files, not as “optimizers.”

Look for:
• No VPN requirement.
• No “1 tap speed up” claims.
• Clear privacy policy and no weird permissions.

  1. If you use Android
    You do not need a third party “RAM booster”.

Use:
• Google Files (by Google). It safely suggests junk to remove, large files, duplicates, WhatsApp junk, etc.
• Built in “Device care” or “Device maintenance” in Settings on Samsung or similar tools on other brands.

Steps:
• Uninstall apps you do not use.
• Clear cache: Settings → Storage → Cached data or per app.
• Move photos and videos to cloud or SD card.
• Keep at least 10–15% free storage. Slowness often starts when storage is too full.

Apps I trust for Android cleaning tasks:
• Google Files, for safe junk and duplicate cleaning.
• SD Maid 2/SD Maid SE, for advanced users who know what they are deleting.

Avoid:
• Anything with “RAM booster”, “antivirus + cleaner + battery saver all in one”.
• Apps that demand accessibility, VPN, or contact access for “cleaning”.

If the phone is still slow after cleanup:
• Check for system updates.
• If it is older than 3–4 years and always near full storage, a full backup then factory reset helps a lot.

On the “best cleaner app,” I’m gonna be a bit of a wet blanket: there is no single magic cleaner that will fix a slow, cluttered phone. And if you chase that, you’re more likely to install junk than remove it.

That said, I’ll add to what @mikeappsreviewer and @shizuka already laid out without rehashing their step‑by‑steps.

First big split: iPhone vs Android

They’re mostly right that system cleaners are overrated, but I’d push back slightly: a good helper app can be useful as a storage inspector, not a “1‑tap optimizer.”


If you’re on iPhone

You don’t need a cleaner that “boosts RAM.” But some apps do a nice job of making the mess visible.

What I’d actually suggest:

1. Use a “storage map” style app rather than a “booster”

Look for an app that basically shows a big visual breakdown of what’s eating space: apps, videos, big files, offline downloads, etc. The ones in the AI cleaner lists that only:

  • scan storage
  • group similar / large files
  • help delete duplicates

are fine as dashboards. Just avoid the ones with:

  • “1‑tap turbo mode”
  • fake CPU temperature, fake battery % “health”
  • constant full‑screen ads or forced VPN

Those are red flags.

2. Let iOS do the actual optimization

Frustrating answer but true: iOS is already the most reliable “cleaner app” on iPhone. A cleaner can help you find 3 GB of forgotten Netflix downloads; iOS is what actually handles memory, background apps, etc.

If an app promises to “make your iPhone like new in 10 seconds,” uninstall it before it makes itself very comfy and hard to remove.


If you’re on Android

Here I slightly disagree with the “never use cleaners” stance. Some third‑party tools are genuinely useful as long as you treat them as file managers not “magic performance buttons.”

1. Google Files
Already mentioned, but I’ll add the nuance: leave autoclean features on a short leash. Let it suggest, then you confirm. I’ve seen it nuke WhatsApp media people wanted to keep.

2. SD Maid SE (if you’re even mildly tech‑curious)
Not for complete beginners, but it’s about as close to “serious cleaner” as Android has. You use it to:

  • see leftover folders from uninstalled apps
  • clean log files and temp junk
  • track down weird hidden storage hogs

Don’t just tap “delete everything” like you’re speedrunning. Read what it’s telling you, or you’ll regret it.

3. What I would not install

  • “Cleaner + Antivirus + VPN + Battery saver + Horoscope” hybrids
  • Anything that constantly runs in the background and brags about killing apps
  • “Game boosters” that claim to increase FPS by 300%

Those usually slow the phone down, nag you with ads, and sometimes sell your data. You’re literally installing the clutter you’re trying to remove.


If you need urgent relief right now

Fastest realistic route that doesn’t repeat what’s already been said:

  1. Check storage: if you’re under ~10–15% free space, that’s probably why it’s lagging. Free space matters more for speed than any “optimizer.”
  2. Delete one or two massive space hogs: old 4K videos, huge games you never open, offline Netflix/Spotify/YouTube downloads.
  3. Disable or uninstall any cleaner / antivirus apps you already installed that constantly show notifications or promise “permanent protection.” Those are almost always performance killers.
  4. Reboot. Simple, boring, still effective.

TL;DR actual recommendation

  • iPhone: the “best cleaner” is iOS itself. Use a reputable storage‑analysis / duplicate‑finder app only as a visual aid, not as a system tuner.
  • Android: use Google Files for basic junk cleanup, and SD Maid SE if you’re comfortable reading what you delete. Avoid everything that screams “boost,” “turbo,” or “1‑tap speed.”

If you say which phone and how full your storage is (e.g., “128 GB, 119 used”), people here can point you to a specific app from the lists @mikeappsreviewer and @shizuka referenced that fits your case instead of a random “best cleaner ever” recommendation.

Skip new apps. Use your browser’s built in tools.

  1. Open Chrome on your phone.
  2. Go to your Google account, then “Manage your Google Account”.
  3. Use “Security” and “Data & privacy” to auto delete old activity, location history, YouTube history.
  4. In Chrome settings, clear browsing data for cached images and files, not passwords.
  5. Do the same in other browsers and in Facebook, Instagram, TikTok settings.

This trims hidden junk and tracking. Many users free 1–3 GB fast.
