Updated for 2026
Ten Android storage cleaners, each checked against its live Play listing: what it costs, whether it shows ads, and what it actually deletes. Pair a good cleaner with a solid file manager and storage worries mostly disappear.
Updated 6 August 2026: every rating, review count, install figure, price and ads label re-checked against the live Play listings. SD Maid 2/SE now shows 4.1 stars and Norton Clean appears on Play as Norton Cleaner.
Picks re-checked 6 August 2026.
| You are... | Get... |
|---|---|
| Most people: just want storage back with zero risk | Files by Google (free, no ads) |
| A power user: app leftovers, duplicates, schedules | SD Maid 2/SE |
| Already paying for Norton, Avast, AVG or Avira | The cleaner bundled with the subscription you already own |
| Allergic to ads and accounts, want the smallest tool possible | SD Maid 2/SE with its one-time unlock, or 1Tap Cleaner Pro |
| Convinced you need no app at all (honestly, fair) | The 60-second no-app method (under Files by Google) |
July 2026 update: only three tools here shipped real news in 2026, all open source; check the detailed review.
| If the app... | Then... |
|---|---|
| asks for contacts, location, SMS or call logs | Walk away. A storage tool needs storage access and nothing else. |
| promises to boost RAM or speed up your phone 90% | Placebo. Android reloads the killed apps seconds later, which costs battery instead of saving it. |
| reached you through a pop-up ad or a "virus detected" warning | Classic scam funnel. Never install a cleaner you first saw in an ad. |
| shows countdown timers or "your phone is 87% damaged" | Fake urgency with invented numbers. Real diagnostics do not rush you. |
| comes from Google or an established security brand with millions of reviews | Probably safe. Still open its permissions after install and revoke anything beyond storage. |

Files by Google is the cleaner to install if you install only one: free, ad free, and it deletes nothing you did not confirm. The blunt con: it is shallow and never finds leftovers from uninstalled apps. For: zero cost, zero ads; review-first removal of junk, duplicates and large files; doubles as a full file manager. Against: no orphan-file hunting; few settings to tune; Smart Storage auto-delete stays Pixel only. Skip it if you want deep cleaning under the hood. Choose Files by Google over SD Maid 2/SE for zero setup and zero surprises.
↑ Back to the comparison1. Open Settings, Storage: on a full phone the space hogs are almost always photos and videos, not cache. 2. In Settings, Apps, sort by size and tap Clear cache on the biggest; never tap Clear data, which wipes your logins. 3. If your photos are backed up, tap "Free up space on this device" in Google Photos; that one button routinely recovers more gigabytes than every cleaner on this list combined. 4. Uninstall apps you have not opened in months. 5. Empty your Downloads folder and old screenshots. Full walkthrough: how to actually free up storage on Android.

4.1 stars, 8.76K reviews · 1M+ installs · free · no ads · Pro unlock 2.89 to 9.99 dollars · by darken · listing checked 6 August 2026
SD Maid 2/SE is the power user pick: it digs out folders left behind by apps you uninstalled months ago and explains every item before you delete. The blunt con: setup is fiddly and its 4.1 rating trails the big brands. Developer Matthias Urhahn is direct on the project site: "SD Maid has no ads and doesn’t sell your data." For: finds leftovers nothing else here touches; open source under GPL v3; one-time unlock, no subscription. Against: fiddly permission setup; smallest install base here at 1M+; scheduling needs Pro. Skip it if you want one tap and no questions. Choose SD Maid 2/SE over Files by Google when you want the junk Files never shows.

4.5 stars, 3.07M reviews · 100M+ installs · free with ads · in-app purchases 1.39 to 39.99 dollars · by Piriform · listing checked 6 August 2026
CCleaner earns its slot on familiarity: the one-button sweep and cache clearing genuinely work. The blunt con: the free version shows ads and pushes the Pro upsell hard. For: familiar one-button cleanup; useful storage analyzer; app hibernation for a monthly sweep. Against: ads in the free tier; Pro nags reaching 39.99 dollars; little that Files does not do politely. Skip it if upsell screens wear you down. Choose CCleaner over Avast Cleanup for the desktop-style sweep; both belong to Gen Digital anyway.

4.6 stars, 1.51M reviews · 50M+ installs · free with ads · in-app purchases 0.99 to 59.99 dollars · by Avast Software · listing checked 6 August 2026
Avast Cleanup is the hand-holding option: a clear visual map of what eats your storage, friendly for less technical users. The blunt con: the best parts, auto cleaning and the deep junk scan, sit behind a paid plan reaching 59.99 dollars. For: clearest storage breakdown here; photo optimizer shrinks large images; guided flow with no jargon. Against: ads in the free tier; core automation paywalled; overlaps almost entirely with AVG Cleaner. Skip it if you refuse subscriptions. Choose Avast Cleanup over AVG Cleaner only for its interface; the engine is near identical.

4.6 stars, 259K reviews · 5M+ installs · free · no ads · in-app purchases 2.99 to 69.99 dollars · by NortonMobile · listed on Play as Norton Cleaner · checked 6 August 2026
Norton Clean is the calm one: junk files, residual data and cache with no ads and no melodrama. The blunt con: it does the least of any big-brand pick here, and the listing now carries an in-app purchases label reaching 69.99 dollars. For: genuinely ad free; simple and quiet; established security developer. Against: fewest features in this group; no duplicate photo tools; renamed listing confuses searches. Skip it if you want photo cleanup or automation. Choose Norton Clean over CCleaner when no ads matters more than extra tools.

4.6 stars, 196K reviews · 10M+ installs · free with ads · Pro 3.99 dollars · by AZSoft Technology Inc. · listing checked 6 August 2026
1Tap Cleaner does what the name promises: cache, call logs and browser history cleared from a home screen shortcut. The blunt con: the interface looks its age and the free version carries light ads. For: fastest route to a clean cache; cheap one-time Pro at 3.99 dollars; tiny and focused. Against: dated design; ads until you pay; no storage analysis. Skip it if you want guidance on what is safe to delete. Choose 1Tap Cleaner over Zero Cleaner for broader clearing and a far stronger rating.

4.7 stars, 733K reviews · 10M+ installs · free · no ads label · in-app purchases 0.99 to 104.99 dollars · by AVIRA · listing checked 6 August 2026
Avira is a security suite with a junk cleaner bolted on, and at 4.7 stars it is the highest rated app on this page. The blunt con: the cleaning tools are basic and paid plans stretch to 104.99 dollars, so it makes no sense for cleaning alone. For: antivirus and cleanup in one app; privacy advisor flags permission-hungry apps; no ads label on the listing. Against: basic storage tools; constant paid-plan nudges; heavier than a dedicated cleaner. Skip it if you only want storage work. Choose Avira over Norton Clean for protection and cleanup in a single app.

4.6 stars, 1.96M reviews · 100M+ installs · free with ads · in-app purchases 1.49 to 39.99 dollars · by AVG Mobile · listing checked 6 August 2026
AVG Cleaner is Avast Cleanup in different clothes, and its duplicate and blurry photo finder clears more clutter than any single tool here. The blunt con: the photo features and automation need the paid tier, and the free version shows ads. For: best duplicate photo detection in this group; huge 100M+ install base; same proven engine as Avast. Against: paywalled automation; ads in the free tier; redundant next to Avast Cleanup. Skip it if you already use its Avast twin. Choose AVG Cleaner over Avast Cleanup if you already live in the AVG ecosystem.

4.4 stars, 157K reviews · 10M+ installs · free trial with ads · in-app purchases 0.99 to 22.99 dollars · by NeatBytes · listing checked 6 August 2026
Solid Explorer is not a cleaner but a dual-pane file manager, and that is the point: you see every folder and decide yourself. The blunt con: no junk detection at all, and after the trial it wants an unlock while the listing carries ads and in-app purchase labels. For: full manual control; polished dual-pane design; cloud storage built in. Against: zero automatic suggestions; trial then payment; ads on the listing. Skip it if you want an app to find junk for you. Choose Solid Explorer over Files by Google to hunt down big folders by hand.

3.8 stars, 6.36K reviews · 1M+ installs · free with ads · in-app purchases 4.49 dollars · by Red Soft · listing checked 6 August 2026
Zero Cleaner clears app cache and nothing else, with no dashboard theatre. The blunt cons: at 3.8 stars it is the lowest rated pick here, it carries ads and in-app purchase labels, and it leans on the accessibility service to work. For: single-purpose and honest about it; optional automatic routine; no scare screens. Against: lowest rating on this page; accessibility permission required; ads in a minimalist tool. Skip it if accessibility-service prompts make you uneasy. Choose Zero Cleaner over 1Tap Cleaner only when cache is literally all you want cleared.
↑ Back to the comparisonOn a modern phone, most booster and RAM cleaner apps do nothing useful. Android manages memory itself: it keeps recent apps loaded because reopening them from memory is faster, and when memory truly runs low the official Android developer documentation says "the kernel starts killing processes to free up memory" on its own, no cleaner involved. Force closing apps just makes the system reload them, which costs battery. What genuinely frees space is boring: uninstall apps you never open, deal with photos and videos, and run the 60-second no-app method in the Files by Google section. Clear a single app's cache only when that app misbehaves; cache is data an app keeps to load faster, not waste.
Not strictly. Modern Android manages cache and memory well on its own, and aggressive RAM boosters can even hurt performance. That said, a good cleaner saves you time finding duplicate photos, huge videos, and leftover files from uninstalled apps. Think of it as a convenience tool, not a fix for a slow phone. If you are happy poking around in Settings yourself, you may not need one at all.
The reputable ones are. We stick to apps from trusted makers like Google, Norton, and Avast, or open and transparent tools like SD Maid. Avoid any cleaner that flashes virus warnings, demands unusual permissions, or promises to double your RAM, since those red flags usually mean ads and tracking. When in doubt, Files by Google is the safest free starting point and asks for very little.
A cleaner scans for junk and suggests what to delete automatically, which is great for hands off maintenance. A file manager gives you full manual control to browse, move, and delete anything yourself. Many people use both. You will find plenty more storage helpers across our tools and utilities guides if you want to dig deeper.
Indirectly, at best. Clearing junk files does not save battery on its own, but some cleaners include tools that hibernate background apps or flag battery draining culprits, and those can help. For real gains, look at a dedicated battery saver app instead. Cleaning storage and saving power are related goals, but they are not the same job, so set your expectations accordingly.
Usually not. Android keeps recently used apps in memory on purpose, because reopening them from RAM is faster than loading them fresh. When a booster force closes those apps, the system often reloads them seconds later, which can use more battery without making your phone feel any quicker. The numbers a booster shows look dramatic, but they rarely change real performance. If your phone feels slow, uninstalling unused apps and freeing storage helps far more than any RAM cleaner.
Very few. A storage cleaner needs access to files and storage, and not much else. Be cautious if one asks for your contacts, location, microphone, camera, or call logs, since none of those are required to delete junk files. Excessive permission requests are one of the clearest signs an app is more interested in collecting data or showing ads than in cleaning your phone. When in doubt, check the permissions on the app store listing before you install.
