Why Is Android 16 Update Slowing Down OnePlus 12R?
if you are noticing the sluggishness particularly afte getting the Android 16 update, it is most probably the culprit. Android 16 is known to bring AI features, better privacy controls, and refined animations. However, what many people overlook is that it can also bloat up RAM usage or conflict with older app data. On the OnePlus 12R, users have reported slower animations and delays while switching apps after update. It might be connected to OxygenOS’s new design elements. The Snapdragon 8 Gen 2 chipset in your phone is a beast, so this isn’t hardwar, it’s software settling in.
We will sort it out without needing a factory reset right away (though that’s a last resort).

Quick Troubleshooting For Android 16 Update Slowing Down OnePlus 12R
These are the low-effort wins that resolve 80 per cent of slowdowns. Give them a shot first.
Do The classic Phone Restart
Sometimes, a simple reboot clears out stuck processes.
- Press and hold the power button > Tap “Restart.” If that doesn’t stick, try a soft reboot: Hold power + volume down for 10 seconds until it vibrates and restarts.
Why it works: Flushes RAM and stops rogue background tasks from the update.
Pro tip: Do this weekly anyway. It’s like hitting refresh.
Wipe the Cache Partition
Android’s cache builds up junk files, and updates can make it worse. Most of the time low storage and cache build up togther make teh phone performance sluggish.
- Power off your OnePlus 12R.
- Press and hold Volume Down + Power until the bootloader screen appears (OnePlus logo).
- Use volume keys to go to “Recovery Mode” > Press power to select.
- In recovery, select “Wipe Cache Partition” > Confirm with power button.
- Reboot from the menu.
Why it works: Clears temporary files without touching your data or apps.

Update Apps and Check for System Patches
Outdated apps can clash with Android 16’s new APIs, causing stutters.
- Open Google Play Store > Tap your profile > “Manage apps & device” > Updates > Update all.
- For system updates: Settings > System > System Update > Check for updates. Install any OxygenOS patches. They often include performance tweaks.
Why it works: Android 16 optimises for newer app versions. Old ones drag things down.
Also, enable auto-updates in Play Store settings to stay ahead.
Free Up Storage Space
Low storage forces the phone to work harder. So maybe it’s not the Android 16 update slowing down OnePlus 12R but the exsisting low storage space. Clear space with these steps:
- Settings > Storage > Free up space > Review and delete large files, unused apps, or old downloads.
- Aim for at least 20% free (your 128/256/512GB drive will thank you).
- Offload to cloud: Use Google Photos for auto-backup and delete locals.
Why it works: Full storage slows read/write speeds. Android 16’s bigger footprint needs room to breathe.

Change Animations for increasing speed
OxygenOS 16’s animations are smoother but can feel drawn-out. It mimicks iOS-style delays. To change settings, go:
- Go to Settings > About phone.
- Tap “Build number” 7 times to enable Developer Options.
- Back to Settings > System > Developer options.
- Scroll to “Window animation scale,” “Transition animation scale,” and “Animator duration scale” > Set all to 0.5x (or 0x for no animations).
Why it works: Reduces visual fluff, making app launches and switches feel instant. Some users have actually reported this fixes post-update “iPhone-like” lag on OnePlus 12 series.
It changes the look slightly, but you can always revert.
Manage RAM and Background Apps
Android 16 ramps up multitasking. Clogged RAM may cause Android 16 update slowing down OnePlus 12R.
- Settings > Battery > More settings > RAM Booster (or High Performance mode if available, toggle it on for heavy use).
- For app management: Settings > Apps > See all apps > Select a culprit (e.g., social media) > Battery > Restrict background activity.
- Use the built-in optimizer: Swipe down from top > Tap the gear > “Optimise now” (or search for “Optimiser” in Settings).
Why it works: Frees up your 12R’s 8/16GB RAM, which gets overloaded by new features.
Close unused apps via recent apps overview, but don’t overdo it. Android handles this better than we think.
