Budget phones get a bad reputation in PUBG Mobile that is only half deserved. The game runs acceptably on 3–4 GB of RAM if you stop it from fighting your device.

The settings that matter
| Setting | Value | Why |
|---|---|---|
| Graphics | Smooth | Everything else costs frames for visual detail you cannot use in a fight. |
| Frame rate | High (not Extreme) | Stable 40 beats oscillating 60/35. Test in a real match before raising it. |
| Anti-aliasing | Off | Pure cost. |
| Shadows | Off | The most expensive single setting in the game. |
| Auto-adjust graphics | Off | It raises settings mid-match and causes the stutter you are trying to avoid. |
Before you queue
- Close every background app. On 3–4 GB devices background memory is the primary cause of late-game frame drops.
- Keep 2–3 GB of storage free — asset streaming hitches on a nearly full device.
- Disable battery optimisation for PUBG Mobile, or the OS will throttle it mid-match.
- Restart the phone if you have been playing for a few hours.
Heat is the real boss
A hot phone throttles, and a throttled phone loses half its frame rate no matter what your settings say. Play with the case off, never charge while playing, keep out of direct sunlight, and take a five-minute break every hour. On a budget device this matters more than any in-game option.
Gameplay adjustments for lower frame rates
- Avoid long-range duels. At 40 FPS, tracking a distant strafing target is a disadvantage. Close the distance.
- Use cover aggressively. Fewer frames means slower reaction; cover buys you the time you do not have.
- Sound becomes your main sense. Use headphones. Audio positioning does not care about your frame rate.
- Prioritise close-range weapons. SMGs and shotguns reward positioning over precision tracking.
When to switch to Lite
If your device cannot hold a stable frame rate even on Smooth, PUBG Mobile Lite exists exactly for that situation: 60-player matches on a compressed map. Codes work there too — see PUBG Mobile Lite codes.
