How to Fix 90 FPS Drop & Overheating in PUBG Mobile (2026 Android Thermal & Touch Sensitivity Guide)

Step-by-step 2026 guide for PUBG Mobile 90 FPS drop fix on Android. Learn how to stop thermal throttling, lock maximum touch sampling rate, and eliminate aim latency.

You launch a competitive match with your graphics settings locked at smooth 90 FPS. For the first ten minutes, gameplay feels buttery smooth, your touch response is instantaneous, and your recoil control is razor-sharp. But as the match enters intense final-circle firefights, an infuriating stutter begins: frames abruptly collapse down to 45 FPS, the back glass of your phone becomes blisteringly hot, and your crosshair aim suffers severe input latency.

Millions of mobile gamers mistakenly assume their device hardware is outdated or that the game servers are lagging. In reality, modern mobile chipsets (Snapdragon, MediaTek Dimensity, and Exynos) are aggressive thermal limiters. The moment internal battery and CPU temperatures cross 42°C, the operating system initiates severe kernel throttling to prevent thermal damage. Applying our verified PUBG Mobile 90 FPS drop fix on Android requires optimizing hardware touch sampling rates, tuning GPU driver layers, and eliminating OS-level background resource contention.

Quick Summary: How to Fix 90 FPS Drops in PUBG Mobile

Why Android Drops Frames During Extended Gaming: The Thermal Wall

Modern smartphone processors generate substantial Joule heat when rendering dense 3D geometry at 90 frames per second. Because smartphones lack active cooling fans, the chassis relies entirely on passive vapor chambers and graphite heat sheets to dissipate thermal energy.

When surface temperatures breach safety thresholds, Android’s thermal-engine daemon automatically downclocks the GPU clock frequency by 30% to 50% to force temperature reduction. Furthermore, aggressive background tasks managed by OEM skins—which we detailed extensively in our Samsung and Xiaomi background whitelist guide—compete for high-performance CPU cores, introducing micro-stutters and frame delivery pacing errors.

Step-by-Step Hardware & Touch Optimization Guide

Step 1: Force Dedicated Game Driver Pipeline

By default, Android routes game rendering through a generic compatibility graphics wrapper. Switching to hardware-level driver processing significantly reduces GPU overhead:

1. Navigate to Settings > System > Developer Options (If not visible, tap Build Number 7 times under About Phone).
2. Scroll down to Graphics Driver Preferences (or Game Driver Preferences on Samsung / Xiaomi).
3. Locate PUBG Mobile in the app list and change its profile from Default to System Graphics Driver / Game Driver.

Step 2: Calibrate Touch Sampling Rate & Aim Sensitivity

FPS drops feel twice as severe when your touch sampling rate lags behind screen refreshes. When playing with sweaty fingers or thick screen protectors, your digitizer can drop touch packets:

• Xiaomi / POCO (Game Turbo): Open Game Turbo, select PUBG Mobile, swipe to Additional Settings, and crank Touch Response and Sensitivity to Continuous Taps to maximum. Set Aiming Precision to Level 10.
• Samsung (Game Plugins / Booster Plus): Install Game Plugins from Galaxy Store, open Game Booster Plus, and configure PUBG Mobile to Max FPS mode. Enable Touch Protection Sensitivity.
• OnePlus / Realme (Game Space): Set performance mode to Pro Gamer Mode and lock Touch Response Rate to High.

Step 3: Disable Battery Optimization & Prevent Throttling Overheat

Gaming while charging is the single fastest way to induce catastrophic thermal throttling. High-wattage fast chargers pump sustained current into the battery pack while the GPU runs at maximum load. As we demonstrated in our benchmark on why fast charging speeds decay past 80%, high voltage creates destructive internal heat.

To maintain low chassis temperatures and prevent permanent cell degradation documented in our 80% battery longevity guide, configure Tekzyro Battery Guard to chime the moment your battery reaches 75%–80%. Disconnecting the charger during intense scrims keeps internal temperatures below 38°C, guaranteeing an unbroken 90 FPS frame line.

Frequently Asked Questions (Gamer Diagnostics)

Does using GFX tools cause accounts to get banned?

Yes. Modifying internal game configuration files (OBB / user custom INI files) via third-party GFX tools violates anti-cheat policies and risks 10-year account bans. The optimizations outlined in this guide exclusively configure native Android OS hardware pipelines and display digitizers, ensuring 100% account safety.

Why does 90 FPS option disappear after updating Android?

Following major OS upgrades, game developers must re-certify GPU profiles for specific firmware builds. Clear the cache of PUBG Mobile and verify your screen refresh rate is locked at 120Hz in system display settings to restore 90 FPS support.
