Phone Overheating Repair in Bangalore — Fixed Same Day
Phone getting dangerously hot during charging or normal use? Screen Guru diagnoses the exact cause — battery, charging IC or software — and fixes it same day. OEM-grade cells, 6-month warranty. Starting from ₹799.
Why Is Your Phone Overheating?
Overheating can come from the battery, the charging IC, the processor or even a software bug. Here are the 6 most common causes we diagnose every day.
Degraded Battery Cell
An aged lithium-ion cell generates more heat as it charges and discharges. The increased internal resistance converts electrical energy into heat instead of stored charge — causing the phone to run hot even on light tasks.
Faulty Charging IC
A damaged charging IC can cause uncontrolled current flow into the battery, generating excessive heat during charging. This is a hardware fault that gets worse over time and can damage the battery further.
Processor Overload
A rogue background app or a corrupted OS process can pin the CPU at 100% load continuously. The processor generates significant heat under sustained load — often mistaken for a battery problem.
Thermal Throttling Failure
Every phone has a thermal management system that throttles performance when hot. If this system fails — due to a software bug or hardware fault — the phone can't regulate its own temperature.
Water / Moisture Damage
Moisture inside the phone can cause short circuits on the motherboard or battery connector, generating localised heat. Even minor water ingress from humidity can cause persistent overheating.
Non-Certified Charger
A cheap or counterfeit charger that delivers incorrect voltage or current bypasses the phone's charging protection circuits, pushing excess energy into the battery and causing dangerous heat build-up.
Overheating Repair in 4 Simple Steps
From free thermal diagnosis to same-day repair — we find the exact cause before touching any hardware.
Free Overheating Diagnosis
Walk in or book online. We run a full thermal diagnostic — battery temperature, CPU load, charging IC output and software processes — at zero cost.
Instant Quote
Transparent upfront pricing for your exact model. You approve before we start — no hidden charges.
Battery or IC Repair
Certified technician replaces the degraded battery or faulty charging IC in 30–60 minutes using professional tools.
Thermal Test & Handover
Phone temperature monitored under load and during charging to confirm overheating is resolved. 6-month warranty on every repair.
Software Overheating vs Hardware Fault — Which Is It?
Not every overheating phone needs a new battery. Check the symptoms below — we'll confirm for free during diagnosis.
Possible Software Issue
May not need battery replacement · Free diagnosis
A rogue background process, bad OS update or misbehaving app can pin the CPU at 100% load — generating heat without any hardware fault. We check software first before recommending any hardware replacement.
- Overheating started immediately after an OS update
- Phone gets hot only when a specific app is open
- Heat comes from the top of the phone (near processor), not the back
- Battery health still shows above 85% in settings
- A factory reset temporarily fixed the overheating
- Phone is less than 1 year old and was never dropped
Battery or Hardware Fault
Battery or IC replacement needed · Starting ₹799
A degraded battery cell or faulty charging IC generates heat as a byproduct of increased internal resistance. This type of overheating happens regardless of software and gets worse over time — replacement is the only fix.
- Phone gets hot during charging even when not in use
- Heat is concentrated on the back panel near the battery
- Phone is 2+ years old and battery was never replaced
- Overheating happens regardless of which app is open
- Battery drains fast alongside the overheating
- Phone has been dropped or exposed to water previously

We don't hand your phone back until temperature is confirmed normal under real-world conditions. Here's exactly what we test.
Thermal Baseline Measurement
Phone temperature measured at rest and under load before repair — establishes the overheating baseline and identifies the heat source.
CPU Load Analysis
Background processes checked for rogue apps or OS issues pinning the CPU at high load — software causes ruled out before hardware work.
OEM Cell Verification
Replacement cell verified for correct mAh rating, voltage spec and fast-charge protocol compatibility before installation.
Post-Repair Thermal Test
Phone temperature monitored under load and during charging after repair to confirm overheating is resolved — not just assumed.
Charging IC Output Check
Charging IC output measured to confirm correct current and voltage — rules out IC fault causing excess heat during charging.
Fast Charging Verified
Fast charge protocol tested — SUPERVOOC, HyperCharge, Apple Fast Charge or Samsung 45W confirmed working at rated speed.
Connector & Seal Inspection
Battery connector and back panel adhesive seal inspected and re-applied to prevent moisture ingress after replacement.
Full Functional Test
All phone functions — calls, camera, sensors, wireless charging — verified working correctly after repair.
