Hey! If your LG phone keeps restarting (random reboots, restart loop, or it’s stuck power cycling), we can narrow down the cause with safe checks — no “nuke it” steps, and no guessing.

People describe this in a few different ways, and each points to different causes:
• LG keeps rebooting randomly (while using apps or just sitting idle)
• Restart loop / boot loop (LG logo appears, then restarts again)
• Reboots only when charging or when unplugging
• Restarts when it gets warm (gaming, hotspot, camera, GPS)

Quick triage — answer any order:
1) Which LG model? (Velvet, V60, G8, Stylo, etc.)
2) When did it start? After an update, new app, new battery/charger, or “out of nowhere”?
3) What does it look like? Full boot loop at the logo, or it gets to the Home screen and then restarts?

Got it — “works briefly, then reboots” is often software (app/services) or thermal/power related, but we can prove which direction it’s leaning without doing anything destructive.

A few questions to steer the diagnosis (not a script — just what matters):
• Does it restart more when you open a specific app? (camera, TikTok/YouTube, games, maps) or it restarts even on the home screen?
• Is it worse while charging? (or only when charging) That can hint at cable/adapter issues or battery/power instability.
• Any heat? Not “a little warm,” but noticeably hot near the back/top.

Also: do you have an SD card installed, and did you install any “cleaner / booster / antivirus” apps recently?

That combo is very “diagnosable”: random reboots even on the home screen + warmer than usual + recent battery saver app + SD card present.

Here’s the safe logic I’d use to avoid chasing symptoms:
Bucket A: A third-party app is destabilizing the system (battery saver/optimizer apps are common triggers).
Bucket B: Heat/power instability (phone reboots to protect itself, or power delivery is unstable).
Bucket C: Storage / SD card / corruption (system services crash repeatedly).

Two checks that don’t erase data and don’t “fix” anything permanently — they just isolate the cause:
1) Safe Mode test: Safe Mode runs only core system apps. If the phone stays stable in Safe Mode, it strongly suggests a third-party app is the culprit. (We’re not uninstalling anything yet — just testing stability.)
2) Temperature pattern: If restarts happen faster when the phone warms up (charging, gaming, hotspot), that points more toward thermal/power.

Before Safe Mode: are you able to get to Settings long enough to see storage space (roughly)? Low free storage can make Android behave wildly.

Totally fair concern — and no, Safe Mode doesn’t delete photos or wipe anything. Think of it as a “diagnostic boot” where downloaded apps don’t run. You can reboot back to normal afterward.

Also, 95% storage is a big red flag for restart loops and app crashes. When Android is nearly out of space, background services can fail, apps can crash, and the phone can restart during cleanup attempts. It doesn’t prove the cause, but it absolutely explains “works for 1–3 minutes then reboots.”

Here’s a safe order that keeps the risk low and the results clear:
Step A (symptom isolation): Safe Mode stability check. If it stays on longer in Safe Mode, you’ve learned a lot without changing anything major.
Step B (storage pressure check): If you can, remove the SD card temporarily (just as a test) and see if the restart timing changes. We’re not formatting it — we’re just checking if the SD card is causing repeated rescans or errors.
Step C (power/heat observation): Note whether restarts speed up while charging. If yes, do a quick test with a different known-good cable/adapter (again, just to observe a pattern, not a “guaranteed fix”).

One more question: when it restarts, does it ever get stuck at the LG logo (boot loop), or does it always make it back to the home screen?

That’s actually encouraging: if it reliably reaches the home screen, it’s less like a deep “boot loop” and more like repeated crashes/restarts once services kick in — apps syncing, storage maintenance, heat management, or power delivery changes during charging.

Since you mentioned both very full storage and a battery saver/optimizer app, here’s a practical “what to do next” approach that avoids doorway-style advice like “factory reset immediately”:

1) Safe Mode = app vs system.
If the LG stays stable in Safe Mode for, say, 10–15 minutes, that points strongly to a third-party app (often the last installed one, or anything that manages battery/performance). If it still restarts in Safe Mode, we lean more toward system/storage/thermal/power issues.

2) Storage breathing room (minimal, not drastic).
If you can stay up long enough, try moving a chunk of photos/videos off the phone (cloud or computer) rather than deleting randomly. You don’t need to “clean everything,” you just want enough free space for Android to operate normally. If helpful later, your related guides like Android phone SD card slow and Android battery drains overnight explain how background activity can spike when storage or power management is stressed.

3) Charging heat pattern.
If it restarts more while charging, use a different cable/adapter for one test. The goal is not “buy a new charger,” it’s to see whether power delivery changes the restart timing.

When you remove the SD card, does the phone stay on noticeably longer, shorter, or about the same?

That’s a huge diagnostic win. If your LG is stable in Safe Mode but keeps restarting in normal mode, it strongly suggests a third-party app (or something it installs, like a “battery saver” service) is triggering the restart cycle.

Notice what we did there: we didn’t “fix” anything blindly — we isolated the variable. That’s exactly how you avoid a doorway page experience and get a real answer for your specific case.

Now, since you also have very low free storage, it’s possible you’ve got two contributors: an app causing instability and storage pressure making it worse. In normal mode, apps sync + cache + update, and if storage is maxed out, the phone can spiral into restarts.

Next safe step (still diagnostic, not a full solution):
• Think timeline: what changed right before the reboots started? New battery saver/optimizer, recent update, or a specific app update.
• One-at-a-time approach: instead of removing a bunch of stuff, identify the most likely offender first (often the most recent “battery saver / cleaner / booster”). If you want to read related patterns, your site also covers problems that can chain-react with restarts, like charging very slowly and battery not charging (power/heat issues can amplify instability).

Quick question before you touch anything: do you rely on that battery saver app for a feature (like blocking background data), or was it more of a “try it and see” install?

Makes sense — and you’re thinking about this the right way. Since Safe Mode stayed stable, you’re not looking at a mysterious permanent boot loop; you’re looking at something that runs in normal mode and pushes the phone into restarts (often a battery optimizer, an app that overlays the screen, or something that hooks into accessibility/performance).

The “what to do next” plan I’d follow — still careful and non-destructive:
1) Protect your data first. If the phone stays stable in Safe Mode, use that window to back up essentials (photos, contacts, notes). That reduces stress before any troubleshooting steps.
2) Confirm the most likely trigger. The battery saver app is top of the list because it was newly installed and interacts with system behavior. Removing it is typically a low-risk change (it doesn’t delete your photos), and it’s consistent with the Safe Mode result.
3) Reduce storage pressure. Aim for breathing room — even a few GB can help. Storage pressure can make “random reboots” look worse than they are.
4) Watch the heat/charging pattern. If it only restarts while charging after the app is gone, that’s a different branch (power/heat) and we’d treat it like a separate diagnostic path.

If you hit anything weird during backup (like the phone exiting Safe Mode by itself), your guide Android consent screen confusing can help you avoid tapping the wrong prompts while you’re rushing.

If you tell me one detail, I can point you to the most likely next branch: when it restarts in normal mode, is it usually right after the phone connects to Wi-Fi/data (apps start syncing), or even with airplane mode on?
