We rely on our phones for nearly everything — communication, payments, directions, even entertainment. But while most of us are careful not to drop or lose them, we often overlook how we store them. Placing it next to the wrong items can lead to overheating, scratches, or even data loss.
5 everyday things you should avoid keeping with your phone
1. Keys can scratch or crack your screen
It’s common to carry your keys and phone in the same pocket or bag — but doing so can cause real damage. Keys have hard edges and sharp corners that can scratch the screen or casing. If it doesn’t have a screen protector, the risk of permanent marks is even higher.
Putting your phone in your back pocket poses an additional risk. Sitting down with it in your pocket can crack the screen or bend the device slightly over time. There’s also a greater chance it could fall out without you noticing.
2. Cash can block heat and attract thieves
Some people like to tuck emergency bills behind their phone case, but that can cause overheating issues. They release heat while operating or charging, and storing anything that blocks airflow — like cash — can interfere with proper heat dissipation.
There’s also a safety concern: if you use a transparent case, visible cash can attract pickpockets in public places. For both security and performance, it’s best to keep your money in a wallet.
3. Liquids can ruin your phone without warning
Even a small leak from a water bottle can destroy your phone if you don’t catch it quickly. Many people toss their phone and drink into the same tote or backpack compartment without thinking twice. If the bottle isn’t sealed tightly or condensation builds up, it can spell disaster for your device.
To protect your phone, carry liquids in a separate compartment, and consider using a waterproof pouch when you’re near pools, beaches, or during rainy weather.
4. Magnetic items can disrupt sensors and signal
Magnets can interfere with your phone’s internal components, especially sensors and the signal receiver. Over time, exposure to magnetic fields can affect the performance, location tracking, and even cause screen glitches.
Some cosmetic products, like lipsticks or blush compacts, use magnetic closures. If the lid clicks shut automatically, there’s likely a magnet inside. Be mindful of where you store these items, especially in a purse or makeup bag.
5. Cards can stick to your case — or disappear
Sliding your ID or credit card between your phone and its case may seem convenient, but it’s a risky habit. In warm weather, cards can stick to the case and may fall out unnoticed. Since we handle them constantly, it’s easy to lose track of small, lightweight items stored with them.
Replacing a lost ID or bank card is a hassle you can avoid by using a dedicated cardholder or wallet.
Smart charging habits can prevent overheating
Even how and where you charge your phone can affect its lifespan. Always place it on a hard, ventilated surface while charging. Beds, sofas, and other soft materials trap heat and prevent proper cooling, increasing the risk of overheating.
If you use a thick or tight-fitting case, consider removing it while charging. This allows heat to escape more efficiently and helps protect your phone from long-term damage due to excessive temperatures. And avoid covering it with blankets or clothing while it’s plugged in — give it space to breathe.
