Phone Overheating While Charging or in Use? Safe Solutions for Android & iPhone

How-to & fixes · 8 min read

Had enough of your phone getting hot every time you charge it, watch a reel, or even answer a call? If your device feels like a tawa, and you’ve tried every trick, it’s time to figure out whether a fix or moving on makes more sense.

Why is my phone overheating while charging or in use?

The most common reasons: streaming videos, gaming, video calls, or charging with a cheap or old charger—especially in the thick of Indian summer. Sometimes, a buggy app, an old battery, or a hardware problem is at fault.

Slight warmth during charging or heavy use is normal. But if the phone gets too hot to hold, throws up overheating warnings, or switches off by itself, that’s a sign something’s off. High humidity, sunlight, or power cuts can make it worse—especially during monsoon or power fluctuations common in many Indian cities.

How can I quickly tell what’s causing my phone to overheat?

Notice when the heat happens. Here’s a table to help you zero in fast:

Ask yourself: Did overheating start after a new app, system update, or a drop? Did your phone get wet, or bake in the sun inside your car? These clues matter. For instance, a phone that stays hot even at night might have a background app stuck, or a battery starting to fail.

What are the safest, quickest fixes for overheating? (Android & iPhone)

First, unplug the charger and remove any case. Let your phone cool down in the shade (never in a fridge or under a fan—sudden cooling can create condensation inside).

1. 1
   Disconnect the charger and remove any case or back cover.
2. 2
   Move the phone away from sunlight, dashboards, and kitchens.
3. 3
   Lower screen brightness. Turn off Bluetooth, GPS, mobile data if not using them.
4. 4
   Close unused apps. On Android, use the multitasking button and swipe away apps. On iPhone, swipe up and pause, then swipe away app cards.
5. 5
   For Android: In Settings, go to Battery or Device Care to see which apps are using power. Force stop or uninstall anything suspicious.
6. 6
   For iPhone: In Settings > Battery, check which apps drain battery in the background. Limit or uninstall those.

If these steps help, keep monitoring. If the phone still heats up, next check the charger and cable.

How do I check if the charger or cable is the problem?

A faulty or fake charger is a classic cause—especially in India, where many shops sell cheap replacements. Here’s how to check:

1. 1
   Look for frayed wires, burnt marks, or a loose fit on your cable and adapter. Swap out anything damaged.
2. 2
   Try using a different certified charger and cable—ideally the original, or a trusted brand.
3. 3
   Don’t use your phone for gaming or streaming while charging. That can double the heat.
4. 4
   Avoid charging from sketchy power sources: old extension boards, or during voltage swings.

If a new charger solves the issue, problem found. If not, it’s likely internal.

What if my phone is still overheating after basic steps? (Advanced fixes)

Still overheating? Try these deeper fixes:

1. 1
   Restart your phone to kill any stuck processes.
2. 2
   Update your phone’s system software and all apps. Most brands fix overheating bugs in updates. For Android, check in Settings under System or Software Update. For iPhone, look under General > Software Update.
3. 3
   On Android: Some models let you clear the cache partition—a deeper clean. Steps vary; check your manual or Google support.
4. 4
   Disable auto-sync. On Android, this is found under Settings > Accounts > Auto-sync data.
5. 5
   For iPhone: Reset all settings (not data) under Settings > General > Transfer or Reset > Reset All Settings. Back up first.
6. 6
   Remove any apps you installed just before the overheating began. Malware sometimes runs in the background and heats up the device.
7. 7
   If all else fails, a factory reset (after backup) can help—but only as a last resort.

A phone that keeps overheating despite all this isn’t safe for long use, especially if the battery’s old or shows swelling.

When should I visit a service centre instead of fixing it myself?

Some problems need a pro. If your phone stays hot after everything above, shuts down on its own, or keeps warning about temperature, it’s time for service. Swollen battery? Back cover popping? Burning smell? Stop using immediately.

If your device has water damage, physical damage, or won’t turn on after overheating, seek an authorised service centre. Batteries and internal repairs should be done by trained technicians. Using a roadside shop could make it worse or void your warranty.

Check Apple’s official support or your Android brand’s support page for the nearest authorised centre.

When is moving on from your overheating phone smarter than trying to repair it?

If your phone’s out of warranty, repairs cost more than what the device is worth, or you’re stuck with the same overheating issue again and again, you’re usually better off letting it go. For older models or when parts are hard to find, that’s even more true in India.

No point hanging on to a phone that heats up or feels risky to use. Cashit takes devices with certain faults, including those with overheating or battery trouble, and the price depends on what’s found during inspection. The online quote you see is just a ballpark—it’s figured from the details you give, but the final number is set only after a technician checks your phone at your place. If you’re satisfied with their offer, you’ll get your money by UPI or bank transfer before the phone leaves your hands.

You can start selling at Cashit for all categories, including sell used Mobile for phones or sell used Laptop for laptops. Getting a quote is free, and there’s no obligation to sell. Devices are securely wiped after receipt, so your data stays safe.

Decision checklist: Should I keep, repair, or sell my overheating phone?

Here’s a sharper way to decide:

• Did the basic fixes (unplug, cool, close apps) solve the overheating? Keep using, monitor for a week.
• Is the phone still uncomfortably hot, even after all the steps? Visit a service centre.
• Is a repair costlier than your phone’s value, or is the device too old for easy fixes? Selling is the smarter option. The quote Cashit gives online is just an estimate; a technician will check your phone in person and confirm the final price.

If you’re unsure, check Cashit FAQs for details on the process, or see the blog on maximizing device resale value.

A real-world example: What happens when you sell an overheating phone on Cashit

Suppose your three-year-old Android phone starts overheating and the battery is swollen. You head to Cashit’s site, fill in a few answers about your phone’s issues, and get an instant estimate. Then you book a doorstep inspection. When the technician arrives, they’ll assess your device and confirm the final offer—sometimes updating it if what they find is different from what you described. If you agree, Cashit pays you over UPI or bank transfer before taking the phone. No bargaining, no tension.
