Summer brings not only high temperatures, but also a higher load for your smartphones. The battery is one of the components that suffers the most from the heat, and an incorrect way of charging can speed up its wear.
If you use a Xiaomi, Redmi or POCO smartphone with HyperOS, it’s worth adjusting your charging settings during hot days. In our new Xiaomi Help article series, we have another practical tip for you on how to protect your smartphone battery.
Heat is the battery’s biggest enemy
Lithium-ion batteries work best at moderate temperatures. Heat naturally builds up during charging, but in summer months the battery temperature can get even higher. It’s the combination of high outdoor temperatures and fast charging that puts the most strain on your battery.
The higher the charging speed, the more the battery heats up. Long-term exposure to high temperatures can gradually reduce its capacity and shorten its overall lifespan.
In summer, it’s better to slow down charging
HyperOS lets you choose between standard charging and maximum speed (Fast Charge or HyperCharge). During hot weather, it makes more sense to use the standard charging mode — it may replenish energy more slowly, but it creates less heat.
The difference in charging time doesn’t have to be significant, but the battery is less strained throughout the whole process. On the other hand, maximum charging speed is especially ideal when you need to charge your phone as fast as possible or during colder months.
How to change the charging mode in HyperOS
It’s simple:
- Open Settings.
- Go to the Battery section.
- Select Charging options.
- In the Wired charging item, choose Standard mode instead of Maximum speed.
If your model supports this feature, you’ll also find an option for Smart charging, which automatically adjusts the charging speed based on temperature, battery status, and how you use the device.
More tips for longer battery life
Besides changing the charging mode, a few simple habits will also help:
- don’t charge your phone in direct sunlight,
- remove the thick protective case during charging if the device gets significantly hot,
- limit gaming or video recording while charging,
- use an original or high-quality certified charger.
Is it worth it?
If it doesn’t matter to you that your phone is charged at any cost in record time, switching to standard charging during summer heat is definitely a smart move.
Lower operating temperature means less battery wear and can help preserve its capacity even after hundreds of charging cycles. A small change in your settings can bring a long-term benefit that every Xiaomi, Redmi, and POCO smartphone user will appreciate.
