1. PERFORM A DEEP STORAGE AUDIT

TO START THE CLEANING PROCESS, YOU NEED TO IDENTIFY THE CULPRITS. APPLE HAS BUILT A POWERFUL ANALYSIS TOOL FOR THIS.

STEP: OPEN SETTINGS > GENERAL > IPHONE STORAGE.

HERE, YOU WILL SEE A BRIGHTLY COLORED GRAPH. PAY CLOSE ATTENTION TO THE CATEGORIES. IF "SYSTEM DATA" OR "APPS" ARE THE LARGEST, YOU NEED TO FOLLOW THE NEXT STEPS CLOSELY.

2. OFFLOAD APPS: THE ULTIMATE TRICK

DELETING APPS IS OLD FASHIONED. OFFLOADING IS THE MODERN WAY! IT REMOVES THE APP PROGRAM BUT KEEPS ALL YOUR DATA SAFE.

HOW TO ENABLE AUTO-OFFLOAD:

GO TO SETTINGS > APP STORE AND TOGGLE ON "OFFLOAD UNUSED APPS". THIS WILL AUTOMATICALLY REMOVE APPS YOU DON'T USE WHEN YOUR STORAGE IS RUNNING LOW, SAVING YOU GBs INSTANTLY!

3. TACKLING "SYSTEM DATA" BLOAT

SYSTEM DATA CONTAINS CACHE, LOGS, AND TEMPORARY RESOURCES. IT CAN SOMETIMES GROW TO 20GB+ WITHOUT ANY REASON.

TECH TIP: CLEARING YOUR SIRI HISTORY AND VOICE DATA CAN OFTEN FLUSH OUT HIDDEN SYSTEM FILES. GO TO SETTINGS > SIRI & SEARCH > SIRI & DICTATION HISTORY.

4. SOCIAL MEDIA & MESSENGER CACHE

APPS LIKE TIKTOK, INSTAGRAM, AND TELEGRAM ARE HUGE SPACE CONSUMERS. THEY SAVE EVERY VIDEO YOU WATCH TO YOUR LOCAL STORAGE.

TELEGRAM STORAGE SAVER:

OPEN TELEGRAM > SETTINGS > DATA AND STORAGE > STORAGE USAGE > CLEAR ENTIRE CACHE. THIS IS THE MOST EFFECTIVE WAY TO GAIN 5-10GB OF SPACE IN SECONDS!

5. REVOLUTIONIZE YOUR PHOTO STORAGE

IF YOUR PHOTOS ARE TAKING UP ALL THE SPACE, YOU ARE PROBABLY NOT USING APPLE'S SMART OPTIMIZATION.

ACTION: SETTINGS > PHOTOS > ENABLE "OPTIMIZE IPHONE STORAGE".

THIS MOVES YOUR MASSIVE 4K VIDEOS TO THE CLOUD AND KEEPS LIGHTWEIGHT VERSIONS ON YOUR PHONE. YOU CAN STILL VIEW THEM INSTANTLY!

6. CLEAR BROWSER JUNK (SAFARI & CHROME)

EVERY WEBSITE YOU VISIT LEAVES BEHIND A SMALL FILE. OVER TIME, THOUSANDS OF WEBSITES CAN CLUTTER YOUR SYSTEM.

• SAFARI: SETTINGS > SAFARI > CLEAR HISTORY AND WEBSITE DATA.
• CHROME: SETTINGS > PRIVACY AND SECURITY > CLEAR BROWSING DATA.

7. THE NUCLEAR OPTION: FRESH START

IF NOTHING ELSE WORKS, A COMPLETE RE-INDEXING OF YOUR IPHONE WILL DO THE TRICK. THIS IS FOR ADVANCED USERS WHO WANT THE CLEANEST POSSIBLE SYSTEM.

1. BACK UP YOUR IPHONE TO ICLOUD.
2. GO TO SETTINGS > GENERAL > TRANSFER OR RESET IPHONE.
3. SELECT "ERASE ALL CONTENT AND SETTINGS".
4. RESTORE FROM YOUR BACKUP.

FINAL SUMMARY: BY ENABLING AUTO-OFFLOAD AND CLEANING SOCIAL MEDIA CACHE WEEKLY, YOU WILL NEVER SEE THE "STORAGE FULL" ERROR AGAIN!
