The lithium batteries in our phones and laptops lose some capacity with every charge cycle, but heat speeds that wear up dramatically. In summer, a phone left in a car can pass 60°C within minutes.
Five habits that protect the battery
- Don’t leave it in the car: not even on the dashboard in the sun for ten minutes.
- Charge somewhere cool: never under a pillow or inside a thick case; take the case off if the phone gets hot while charging.
- Avoid the extremes: staying between 20% and 80% is kinder to the battery than draining it and filling it every day.
- Use a reliable charger: cheap chargers may not control current and heat properly.
- Don’t game while fast-charging: heavy load plus charging drives the temperature up fast.
When to replace the battery
If your phone switches off at 15% or 20%, the percentage drops noticeably fast, or it needs charging twice a day, the battery has probably lost more than a fifth of its capacity. We measure its health at the shop in minutes.
A swollen battery is dangerous
If the screen or back cover is lifting away from the frame, stop charging straight away, don’t press on the device, keep it away from anything flammable and bring it to us. Don’t try to open it yourself.
