Clean Up Photos Before a New Phone (Checklist)

Why clean up photos before a new phone

Clean up your photos before a new phone arrives, on the old one. A transfer copies everything you give it, so years of blurry shots, screenshots and forgotten videos land on the new phone too. Sort first and the new phone starts with only the photos you want.

Once the new phone is in your hand, the old one goes in a drawer and the sorting never happens. If a new phone is on your list for Black Friday or Christmas, the weeks before it arrives are the window.

You do not need to finish. A partial sort still shrinks the transfer, and ten minutes a day for a week is easier to keep up than one long evening.

Oust is on Android. The iPhone tips below use Apple’s own tools.

If you only have 15 minutes

If you only have 15 minutes to sort photos before a new phone, do these four things, in this order. The steps below explain each one.

1. See what takes the space. On Android, open Settings, tap Storage, then a category (Google help, checked 15 October 2026).
2. Make sure a full backup exists, and check it from another device (Step 1).
3. Sort the videos only. They are where most of the space usually sits.
4. Empty the trash at the end, as in Step 5.

Step 1: back up before you delete anything

Make a full backup before the first deletion, so you can decide fast without fear.

• Google Photos backup. Turn on Backup in Google Photos settings and wait until it says everything is backed up (Google help). The copies count toward your Google Account storage, shared with Gmail and Drive, with up to 15 GB at no cost (Google help, checked 15 October 2026).
• A computer or an external drive. Copy the camera folder (usually DCIM) with a cable. If the phone has an SD card, copy its photo folders too. It costs nothing and keeps a copy outside any account.
• Both, if the photos matter a lot. Two copies in two places is the usual rule for anything you cannot replace.

Cloud backups like Google Photos sync with the phone, so a deletion on the phone may follow to the cloud copy. For photos that matter, the copy on a computer or drive is the one that cannot change.

Check the backup from another device before you start deleting. A backup you have never opened is a guess.

Step 2: let your phone find identical copies first

Before sorting by hand, let a free built-in tool catch the copies of the same photo.

• Android. Files by Google lists identical files in its Clean section and badges the original in each group, so you can keep that one and remove the rest (Google help, checked 15 October 2026).
• iPhone, iOS 16 or later. In Photos, scroll to Utilities (under Collections, or in the Albums tab on iOS 16 and 17), where Apple gathers copies of the same photo or video in their own album and lets you Merge each group (Apple help, checked 15 October 2026). Apple says the detection runs while the iPhone is locked and charging, and can take a few days on a large library (Apple help), so start it early.

Oust does not detect duplicates, so run these tools first and sort what is left.

Step 3: sort into three piles

Look at each photo once and give it one of three answers: keep, delete or later. The photos that slow a sort down are the few you hesitate over, and a later pile lets you skip them without deciding.

Your phone’s gallery can do it a screen at a time. That works for screenshots, but it gets slow across thousands of photos, and the gallery has no quick way to set the maybes aside.

A sorting app shows one photo at a time and turns each answer into a gesture. In Oust, you swipe left to delete, right to keep and down for Later. Photos you swipe left go to an in-app list, Photos to delete, opened with View Trash, and nothing leaves the gallery until you confirm there. If you swipe the wrong way, Undo reverses the last swipe. The full method is in the guide to swiping through an Android gallery. Oust is on Android today, from Google Play. iPhone is coming soon.

When in doubt, swipe down: before a transfer, clearing the obvious is enough. Delete what you will never miss, like the fifth shot of the same scene, old screenshots, receipts, parking spots and blurry attempts.

Step 4: start with the videos

Sort the videos before the photos. A minute of video usually takes far more space than a photo, so a short session on videos often does more for the transfer than an evening on pictures.

In Oust, open the filter and choose Videos only. The deck then shows only videos, in random order by default or in Timeline order (Newest first by default, or Oldest first). Old videos tend to be the easiest calls, like a concert you never rewatched or ten seconds of pocket.

Once the videos are done, switch the filter to Photos only (or Photos & Videos) and keep going.

Step 5: review the maybes, then empty every trash

Deleted photos are not gone yet. Samsung Gallery, Google Photos and iPhone Photos keep them in a trash for 30 days so you can change your mind, and they still take space there. Settle the later pile first, then empty the trashes, then transfer.

Give the later pile a second look a few days after the sort. In Oust, open the Later tab and swipe each photo left or right.

With Oust, confirming in Photos to delete asks Android to delete the photos. On Android 11 and later, Android shows its own confirmation and the photos then wait in the phone’s trash for about 30 days. On Android 10 and earlier there is no trash, and Oust warns you that the deletion is permanent.

Where deleted photos wait	How long	How to empty it
Oust, Photos to delete	Until you confirm	Open View Trash and confirm
Phone trash, Android 11 and later	About 30 days	Look in your gallery app’s trash, which varies by phone. Android removes them by itself after about 30 days
Samsung Gallery	30 days (Samsung help)	Gallery trash (called Bin in some One UI versions), or My Files › Recycle bin › More › Empty
Google Photos	30 days (Google help)	Trash in Google Photos
iPhone Photos	30 days (Apple help)	Recently Deleted album

If a cloud backup syncs with the phone, deleting on the phone may delete the cloud copy too. Empty the trash only once you have checked your backup (ideally the copy on a computer or drive, as in Step 1), because an emptied trash cannot be restored. Whether a transfer tool copies items in a trash depends on the tool, and emptying first removes the question.

Step 6: transfer what you kept

Transfer once the sorting and the trashes are done, with your phone maker’s own tool.

iPhone › Android	Google’s setup on the new phone	Data from the iPhone, with a QR code or a cable	Google help
Any › any	Google Photos backup	The backed-up library, when you sign in	Google help

Photos kept only in the cloud are not on the phone, so a phone-to-phone copy may not carry them. They come back when you sign in to the same cloud account on the new phone.

On an iPhone, empty Recently Deleted first, as in Step 5. If iCloud Photos is on, Apple says it stores the originals in iCloud, and with Optimize Storage the iPhone keeps only space-saving versions (Apple help, checked 15 October 2026). Check that iCloud has finished syncing before you erase anything.

Chats travel separately. From Android to iPhone, Move to iOS can also carry WhatsApp messages and media (Apple help). Otherwise, WhatsApp keeps its own chat backup, which you restore inside the app on the new phone (WhatsApp help). The photos it saved to your gallery show up in Oust like any others.

Step 7: before you reset the old phone

Reset the old phone only after the new one has everything. Do not assume the transfer copied it all.

• Check the photos arrived. Open a few albums on the new phone, including the oldest ones and the videos.
• Keep the old phone a few days. Sign-in codes and app approvals may still go to it, and authenticator apps do not always move by themselves. Check each one on the new phone first.
• Take out the SD card and the SIM. Photos can sit on an Android phone’s SD card, which a phone reset may not erase. If you use an eSIM, move it with your carrier’s steps first.

Then sign out and reset. On Android, remove your Google account from the old phone, which Google says turns off device protection (Google help). Then use the reset in Settings, following your phone maker’s help for the exact path (Google help). On an iPhone, Apple’s trade-in help says to unpair your Apple Watch if you have one, sign out of your Apple Account, then use Erase All Content and Settings (Apple help, checked 15 October 2026). A reset erases every photo still on the phone, so this is the step with no way back.

The January clean-up after the holidays

Clean up in January with the same three piles. The holidays often add hundreds of photos in a few days.

1. December videos first. Choose Videos only, then Timeline with Newest first. Keep the one or two videos that matter per event.
2. Then the photos, on a timeline. Bursts sit next to each other, so keep the best shot and swipe the rest left, as in the swipe method.
3. Review Later a week after, then empty the trash, as in Step 5.

The checklist

1. Back up the full library, SD card included, ideally to a computer too, and check the backup from another device.
2. Let Files by Google or iPhone Photos catch the identical copies.
3. Sort the videos first, with a videos-only filter.
4. Sort the photos into keep, delete and later.
5. Review the later pile, confirm the deletions, then empty every trash (the app’s list, the phone’s trash, the cloud trash) once the backup is checked.
6. Transfer with your phone maker’s tool or the cloud.
7. Check the new phone, keep the old one a few days, remove the SD card and SIM, sign out, then reset.

What this guide doesn’t cover

This guide leaves out automatic sorting: Oust has no AI, does not spot blurry or similar shots, and cannot filter by album or sort by file size.

Google Photos’ Free up space on this device removes the phone copies of photos already backed up, which suits people who keep their library in the cloud (Google help). That tool and the ones in Step 2 find candidates for you. Oust is for deciding photo by photo, quickly.
