For years, I treated a phone case and tempered glass protector as essential accessories. Whenever I bought a new smartphone, they were among the first things I ordered.
Recently, though, I stopped using both on my Samsung phone. What began as an attempt to reduce heat buildup ended up changing how I think about phone protection altogether.
After several months without a case or screen protector, I've found there are some genuine advantages to using a modern smartphone as it was designed. In this article, I'll explain why I stopped using them, what I gained, and the trade-offs you should consider before doing the same.
Quick summary: I removed the case and tempered glass from my Samsung phone to see if it would help with heat and daily comfort. The phone feels cooler and more responsive without them, but this doesn’t mean everyone should go without protection. Your phone, usage habits, and environment should decide whether keeping a case or screen protector makes sense.
Why I Removed the Case and Tempered Glass From My Android Phone
I use a Samsung phone with an AMOLED display and a large battery, but I'm far from a power user on this phone. Most days, it's just online shopping, YouTube, web browsing, Google Maps, and the occasional Uber ride. I don't game on it, and I rarely use it for music.
Even so, the phone would often get warmer than I expected, especially outdoors. Navigation apps like Google Maps and Uber keep the screen bright and GPS active, which can generate a surprising amount of heat on a hot day.
My phone has a vapour cooling chamber, but with a thick case on the back and tempered glass on the front, it often felt like that heat had nowhere to go. After weeks of noticing it, I removed both. The difference was immediate. The phone still gets warm when it's working hard, but it no longer feels like it's holding onto the heat.
Smartphone Cases Trap Heat More Than We Admit
Most phone cases are designed for drop protection, not heat management.
TPU and silicone cases add an extra layer around the phone, and in my experience, that made heat more noticeable during charging, navigation, and outdoor use. I’ve tried several cases, but the phone always felt more comfortable without one.
Cases still have their benefits. They improve grip and protect against drops. But if your phone already runs warm, a thick case can make everyday use less comfortable. That was one of the reasons I decided to stop using one.

Tempered Glass Also Has Its Downsides
Tempered glass is considered a must-have, but it also changes the way the phone feels. It protects against scratches and drops, but the extra layer can affect touch response.
On my phone, I had to increase touch sensitivity from Settings because the screen didn’t feel as responsive. After removing the glass, I switched it back to normal, and the display felt better immediately.
Outdoor use also became more comfortable. The phone no longer felt as hot against my hand or ear. Tempered glass isn’t useless, but for me, the trade-off wasn’t worth it.
Exynos-powered Samsung phones can already run warm under load. Apps like Google Maps and Uber make this more noticeable in hot weather, with heat building around the top of the display and the camera area. Adding a case and tempered glass only made it worse.
During winter, I don’t mind using tempered glass. The heat issue is mainly noticeable in warmer conditions, especially outdoors, when the phone already has a harder time staying cool.

Modern Phones Are Tougher Than Before
Phones today are generally tougher than they used to be, but that doesn’t mean every phone is built the same. Many modern Samsung and Android devices come with stronger glass, better frames, and improved protection ratings, but plenty of phones still benefit from a screen protector.
Not every phone has the same durability, and not every user treats their phone the same way. If your phone scratches easily, has weaker glass, or you’re prone to drops, tempered glass is still a smart investment.
In my case, I decided to skip it because my phone already runs warm and I noticed a difference in daily comfort without the extra layer. If your phone doesn’t have heat issues, there’s no real reason to remove tempered glass. The added protection is worth keeping.
I’d still use a case because glass backs are slippery, and a case with raised edges can help protect the screen during drops. For me, the case stays — the tempered glass was the part I was willing to give up.
FAQs — Frequently Asked Questions
Does a phone case cause overheating?
Phone cases usually do not directly cause overheating, but thick TPU or silicone cases can trap heat and make phones feel noticeably warmer during gaming, charging, GPS navigation, or outdoor use.
Does taking off a phone case help with overheating?
Often yes. Removing the case improves heat dissipation, especially if it's thick or poorly ventilated.
Is it safe to use a phone without a case?
Modern smartphones are more durable than older devices, especially flagship phones with Gorilla Glass and water resistance. However, using a phone without a case still increases the risk of scratches and damage from accidental drops.
Can tempered glass cause heat?
Tempered glass usually does not increase internal phone temperature significantly, but it can hold extra surface heat and make the screen feel warmer during outdoor use or prolonged brightness-heavy tasks.
What are the disadvantages of tempered glass?
It adds slight bulk, can crack or shatter on impact, and poor-quality ones reduce touch sensitivity or clarity.
Tightened version with a balanced ending and a more natural personal tone:Final Thoughts
After using my phone without a case and tempered glass for a while, I prefer it this way. It feels better in hand, more natural to use, and the reduced heat buildup is noticeable, especially during summer.
That said, this approach isn’t for everyone. If you drop your phone often or others regularly use it, keeping both protections still makes sense. Personally, I’ll continue using a case, but I’m comfortable skipping the tempered glass.
If your phone runs warm and you’re careful with it, try removing the tempered glass for a week and see how it feels. But if protection matters more than comfort, keeping the screen protector installed is still the safer choice.
Yes! I admit that thick cases and tempered glass screen protectors trap heat. However, I still can't take the risk of getting my phone damaged due to physical damage. Instead of removing the tempered glass I remove the phone case when it gets warm while I'm outside.
ReplyDeleteYeah, that's a pretty reasonable compromise. Thick cases and tempered glass can trap some heat, but they also protect the phone. Taking the case off when the phone starts getting warm can help it cool down a bit without giving up protection completely.
