Why Samsung Phones Overheat and How Repairs Fix It

Introduction

It’s a familiar problem for many Samsung users — you pick up your phone, and it feels unusually hot. While it’s normal for smartphones to generate some heat during charging or heavy use, persistent overheating is a warning sign. Left unchecked, it can shorten your phone’s lifespan, cause serious performance issues, and even pose safety risks.

At iRepair Experts Brisbane, we regularly help customers fix overheating Samsung phones. In this article, we’ll explain why Samsung phones overheat, the dangers of ignoring it, and how professional repairs can restore your device to safe and reliable performance.

Common Causes of Samsung Phone Overheating

Several factors can make your Samsung device run hotter than normal:

Heavy Usage & Gaming
Samsung phones are powerful, but high-intensity tasks like gaming, video editing, or running multiple apps simultaneously put extra stress on the CPU and GPU. This workload generates heat.
Background Apps Draining CPU
Apps running in the background — especially social media or GPS apps — constantly draw processing power, which can overheat your device even when you’re not actively using it.
Damaged or Old Battery
Batteries degrade over time. A swollen or failing lithium-ion battery often produces more heat than a healthy one. This is one of the most common overheating issues we see in our Brisbane repair store.
Faulty Charging Cable or Port
Using cheap third-party chargers or having a damaged charging port can create irregular power flow. This not only overheats the phone but can also be dangerous.
Software Glitches or Malware
Outdated software, rogue apps, or malware can cause the CPU to overwork, leading to excessive heat.
Hardware Issues (Motherboard / Power IC Problems)
Sometimes overheating isn’t caused by user behaviour but by failing internal components. When the power IC chip or motherboard is faulty, heat builds up rapidly.

Risks of Ignoring Overheating

Some users simply put their phone down and wait for it to cool. But persistent overheating is not something to ignore. It can lead to:

Reduced Battery Life – heat speeds up battery wear, forcing more frequent replacements.
Random Shutdowns & Lagging – overheated processors throttle performance to cool down, leaving you with a sluggish device.
Screen Damage – high internal temperatures can warp or permanently damage your AMOLED display.
Safety Hazards – in rare cases, extreme heat can cause batteries to swell, leak, or even ignite.

Overheating isn’t just inconvenient — it can be dangerous.
