Especially now that smartphones are so slender that replacing the battery is a complicated task, battery health has become a major issue. This article provides some useful tips and helpful advice.
Different types of battery require different types of treatment to keep them running at their best. That is why you may have heard contradictory advice. The tips in this article apply to the modern lithium-ion battery that you will find in most mobile phones.
Don’t let it run empty or charge fully
Do you always charge to 100% and wait until the phone dies before recharging? This principle dates back to the past, when the batteries were based on a different technology. For modern mobiles, it is now advised to keep your battery at a charge of between 30% and 80%.
Don’t charge overnight
Leaving your smartphone on charge overnight is convenient, but it damages the battery. It is therefore better to charge your phone during the day – ideally switched off or in airplane mode. The good news is that newer smartphones come with battery protection, which reduces the wear on your battery and improves its lifespan by reducing the time your phone spends fully charged.
Enable battery protection
In newer smartphones, this feature is already integrated and improves battery life automatically. With an iPhone, you can turn on the ‘Optimised Battery Charging’ option or activate Smart Charge mode on Huawei models. Samsung and Sony also have a number of useful tips to save your battery.
Use smart gadgets
With a smart power outlet, you can limit the flow of electricity to, for example, 2 hours per night. Or you can connect your mobile phone to a power bank for overnight charging. This is gentler than a standard power outlet.
5 golden rules
- Don’t overload the battery: Don’t make phone calls or use power-hungry apps while charging.
- Use a standard charger: A fast charger (from a current of 2 amps) will heat the battery more.
- Remove the phone case: If your smartphone becomes unusually hot when charging, it is best to remove the case.
- Avoid cheap chargers: Only use batteries from the mobile phone manufacturer and chargers bearing the CE marking as well as wireless chargers with Qi certification.
- Charge your phone on a safe surface: Batteries can become swollen or even set alight. Therefore, be sure to place your phone on a non-flammable surface.
