With temperatures soaring across the UK, most of us are thinking about staying cool – but what about our business mobile phones?
Modern smartphones are incredibly powerful, but they don’t enjoy extreme heat. Whether you’re travelling between customer meetings, working outdoors or simply leave your phone on the dashboard of your car, excessive temperatures can affect performance, shorten battery life and even cause your device to temporarily shut down.
Here are some simple ways to keep your business mobile phone running smoothly during the summer months.
1. Keep Your Phone Out of Direct Sunlight
It may sound obvious, but one of the quickest ways to overheat a phone is to leave it in direct sunlight.
Avoid placing your phone on:
- A car dashboard
- A windowsill
- Outdoor tables in direct sunshine
- Black surfaces that absorb heat
Even on a typical British summer’s day, temperatures inside a parked car can rise surprisingly quickly, far exceeding the outside temperature.
2. Avoid Charging in Extreme Heat
Charging naturally generates heat inside your phone. If the device is already warm from being outside, charging it immediately can make matters worse.
If possible:
- Charge your phone indoors.
- Remove thick protective cases if they trap heat.
- Avoid using fast charging when the phone already feels very warm.
- Unplug the phone once charging has completed rather than leaving it connected unnecessarily.
3. What Happens if a Phone Gets Too Hot?
Most modern smartphones include built-in protection systems.
If the internal temperature rises too high, your phone may:
- Dim the screen brightness.
- Slow down performance.
- Pause charging.
- Disable the camera or flash.
- Display a temperature warning.
- Shut down temporarily until it cools.
Although this can be inconvenient, it’s actually designed to protect the internal components.
4. Never Put a Hot Phone in the Fridge or Freezer
One of the biggest myths is that you should cool an overheating phone by putting it in the fridge or freezer.
Don’t.
A sudden change in temperature can cause condensation to form inside the device, potentially damaging sensitive electronic components.
Instead:
- Move the phone into the shade.
- Remove any protective case.
- Stop using processor-intensive apps.
- Turn the phone off if necessary.
- Allow it to cool naturally in a well-ventilated room.
A few minutes of patience is much safer than exposing your device to rapid temperature changes.
5. Heat Can Permanently Reduce Battery Life
Heat doesn’t just affect your phone today—it can affect it months from now.
Business smartphones use lithium-ion batteries, and excessive heat speeds up the natural ageing process inside the battery.
Repeated overheating can:
- Reduce maximum battery capacity.
- Shorten the amount of time the phone lasts between charges.
- Increase battery wear over time.
While occasional warm weather isn’t usually a problem, regularly leaving a phone in hot cars or direct sunlight can permanently reduce battery performance.
6. Close Unnecessary Apps
If your phone is already warm, reduce the amount of work it’s doing.
Closing unused apps, stopping video streaming and limiting processor-intensive tasks can help reduce heat generation.
If you’re working remotely, using Wi-Fi where available can also reduce battery consumption compared with poor mobile signal areas where the phone has to work harder to maintain a connection.
7. Keep Your Software Updated
Software updates don’t just introduce new features—they often include battery optimisation and thermal management improvements that help devices run more efficiently.
Keeping your phone up to date helps ensure it performs as intended during warmer weather.
Business Communication Doesn’t Stop Because It’s Hot
Whether your team is working from the office, visiting customers or working remotely, reliable communication remains essential.
Business mobile phones and cloud-based VoIP systems help employees stay connected wherever they’re working. Features such as Wi-Fi Calling, mobile apps and call forwarding mean your business can continue operating smoothly even during the hottest days of the year.
