Pixel 8a Overheat Teardown: Can We Fix It? [Complete Guide + 7 Proven Fixes]
Introduction: Why Pixel 8a Overheating Matters
Google’s Pixel 8a is one of the most popular mid-range smartphones in 2025, praised for its excellent camera, clean Android experience, and AI-powered features. However, many users have reported Pixel 8a overheating issues—especially during gaming, video calls, or even while charging.
Overheating isn’t just uncomfortable—it can reduce performance, damage internal components, shorten battery lifespan, and even cause permanent phone failure if not addressed. This is why understanding the Pixel 8a overheat teardown is crucial. In this guide, we’ll break down what’s inside your Pixel 8a, identify heat-sensitive parts, and explain whether DIY fixes or professional repairs are the best solution.
Pixel 8a Hardware Overview
Before diving into the teardown, let’s quickly look at what powers the Pixel 8a.
- Processor (Google Tensor G3 chip) – A powerful SoC but known for high thermal output.
- Battery (4,385 mAh) – Can heat up during charging or intensive apps.
- Cooling System – Thin graphite sheets and thermal pads designed to dissipate heat.
- Display – A 6.1-inch OLED panel that also generates heat when running at high brightness.
- Camera System – Advanced image processing puts extra strain on the processor.
Key Components Contributing to Heat
- Tensor G3 processor: Optimized for AI but less power-efficient under heavy loads.
- Battery: Degradation increases heat production.
- Charging circuit: Generates excess heat during fast charging.
Thermal Management System Inside the Pixel 8a
Google uses graphite thermal pads, a metal mid-frame, and software thermal throttling to regulate temperature. However, these systems are often insufficient during extended use.
Common Causes of Pixel 8a Overheating
Software Bugs & Updates
Unoptimized software updates can cause background processes to spike CPU usage.
Hardware Inefficiencies
- Tensor chips naturally run hotter compared to Snapdragon counterparts.
- Worn-out batteries or faulty power ICs worsen the issue.
Environmental Triggers
- Direct sunlight exposure
- Gaming or video editing in hot environments
- Using non-certified fast chargers

FAQs About Pixel 8a Overheating
Q1: Why does my Pixel 8a get hot during charging?
Because fast charging pushes high current through the battery, generating heat. Using certified chargers helps.
Q2: Can overheating damage my Pixel 8a permanently?
Yes. Prolonged overheating can warp the battery, damage the processor, and shorten your phone’s lifespan.
Q3: Does replacing the battery fix overheating?
In many cases, yes. A new battery reduces thermal stress.
Q4: How do I know if overheating is software or hardware related?
Check if it happens after an update. If yes, it’s likely software. If it happens randomly, hardware may be at fault.
Q5: Is Pixel 8a more prone to overheating than Pixel 7a?
Yes. The Tensor G3 chip is more powerful but generates more heat than the Pixel 7a’s chipset.
Q6: Should I attempt a teardown myself?
Only if you have repair experience. Otherwise, take it to a trusted repair centre.
