Hi! If your LG phone feels slow after an update, we can narrow down what’s going on using safe, senior-friendly checks — no factory reset, no risky “wipe cache partition” steps, and nothing that should delete photos.

People describe “slow” in a few different ways, and each points to different causes:
• Lag / stuttering when opening apps or switching screens
• Freezing (touch doesn’t respond for a moment) or apps “Not responding”
• Battery drain + heat after the update (phone warm even when you’re not using it)
• Slow typing (keyboard lags) or messages take longer to send/load
• Slow internet only (websites load slowly but menus are fine)

Quick triage — answer any you can, any order:
1) Which LG model? (Velvet, Stylo, K series, G/V series, etc.)
2) When was the update installed? Today, yesterday, or a week ago?
3) Is it slow everywhere (Settings + home screen) or mainly inside a few apps?

You’re doing the right thing by avoiding resets. Two nights ago is also a key detail because right after an Android update, phones often do a lot quietly in the background: finishing app updates, re-indexing photos, optimizing apps, rebuilding caches. For some people it looks like “my LG got slow after update,” but it can calm down after it finishes those tasks.

Simple explanation of the main buckets we test (without guessing):
• Normal post-update settling: temporary lag while the phone optimizes and apps update in the background.
• Storage pressure: low free space can make everything feel heavy — apps open slowly, keyboard lags, and the phone pauses.
• One app misbehaving: a specific app update (keyboard, Messages, launcher) can cause stutters across the phone.
• Heat/battery saver behavior: if the phone runs warm, it can slow itself down; battery saver can also reduce performance.

A few gentle questions (choose what’s easy):
• Does it feel warm when it’s just sitting there?
• Is storage nearly full? Even “almost full” can cause lag.
• Is the problem worst in Messages/keyboard, or is the Settings menu also slow?

That combination (battery dropping faster + a bit of overall lag) can happen during post-update settling — but “storage might be close” is one of the most common causes of a slow Android phone, especially for seniors who store lots of pictures and videos.

Safe checks that don’t delete anything by surprise:
1) Storage sanity check: just look at how much free space is left. If it’s very low, the phone can stall when apps try to save temporary files (which affects Messages and the keyboard).
2) Background activity clue: if the phone is doing a lot after the update, you’ll often see the battery drain even when not used much, and apps may open slower for a couple days.
3) Battery Saver check: if battery saver is enabled automatically, it can make the phone feel less “snappy.” The point isn’t to change it instantly — it’s to notice whether it’s on and whether the slowdown matches it.

If you’d like, there are also related guides that cover common “slow phone” helpers without risky steps, like storage and SD card behavior: Android phone SD card slow – how to fix safely and Android phone SD card slow – simple explanation.

One question that helps a lot: does your mom use an SD card for photos, or is everything stored on the phone’s internal storage?

That’s actually a pretty “normal” post-update story: a wave of app updates, then the phone stutters while everything catches up. The camera and social apps are heavier, so they show the slowdown first.

Here’s a simple way to separate normal settling from a real problem (without doing anything destructive):
• Time test: is it gradually improving each day, or staying the same/worse?
• Idle test: if the phone sits unused for 10–15 minutes, does it behave better right after? If yes, background tasks may be the main culprit.
• One-app test: if one specific app (like Facebook) consistently causes the biggest lag, it might be an app update issue rather than the whole phone being “bad.”

Since this is “easy help for seniors,” I try to avoid complicated menus. But one very safe diagnostic tool is Safe Mode (temporary). Safe Mode turns off third-party apps for a moment. If the phone feels smooth in Safe Mode, that’s a big clue that one app is dragging things down.

Before we even consider Safe Mode: are you noticing pop-ups or a new “cleaner/booster” app after the update? Those can also slow phones down.

Good observation — slow charging can be separate, but it can also “feel” worse after an update if the phone is doing heavy background work and using more power while charging. It doesn’t automatically mean anything dangerous, but it’s worth watching the pattern calmly.

If slow charging is part of the story, this related guide can help you compare safely (no tools needed): Android phone charging very slowly – what to do next.

Back to performance: for seniors, the most important thing is reducing frustration without risky changes. So I’d focus on checks that give clear clues:
• Storage check (low space can cause pauses, especially in the camera and messaging)
• Battery saver check (may lower performance to extend battery life)
• App update check (a single app can trigger lag, even if the phone itself is fine)
• Safe Mode comparison (diagnostic only) if the issue persists

One more question: is the phone also slow on Wi-Fi only (web pages loading) or is the slow feeling mostly inside the phone (opening apps, typing, switching screens)?

That “overnight battery drop” is a valuable clue. After an update, it can happen while the phone finishes background tasks — but it can also happen if an app is stuck working in the background (syncing, backups, media scanning). That same background activity can make the phone feel slow and make the keyboard lag behind your taps.

Since you mentioned overnight drain, here’s a related reference that explains the pattern clearly: Android phone battery drains overnight – simple explanation.

A safe diagnostic thought process (no heavy “do this, do that”):
• If the phone is improving day by day, it’s likely settling + app updates finishing.
• If it’s stable but slow and storage is low, storage pressure is a strong suspect.
• If battery drains overnight and the phone stutters all day, a background app or service could be looping.

If you’re comfortable, the single best “proof test” for the app theory is Safe Mode. It doesn’t solve everything, but it tells you whether third-party apps are involved.

Would you say the slowdown started immediately after the system update finished, or did it show up the next morning after apps updated?

That timeline (“worse the next morning”) fits app updates + background syncing more than a broken phone. And your concern about popups is valid — not because it proves malware, but because some apps try to get permission to run over other apps or send lots of notifications, which can make older phones feel sluggish.

If your mom sees confusing permission screens, this guide can help you spot what’s normal vs suspicious without panic: Android phone consent screen confusing – simple fix.

Here’s the safest way to interpret results (so you don’t end up chasing random settings):
• If storage is very low, that’s a straightforward reason for “slow after update” — updates need breathing room.
• If Safe Mode feels noticeably smoother, a third-party app is likely contributing (keyboard, launcher, social app, or something running in the background).
• If Safe Mode feels the same, it’s more likely system settling, storage pressure, or a general performance limit of the device — still not a reset situation, just a “which pressure is it?” situation.

For seniors, the win is getting the phone back to “predictable.” If you do only one test, do a Safe Mode comparison and a storage check. That gives you clean evidence without risky moves.
