Battery Myths Busted: Full Charging

A full charge of the battery does not mean it does not have any more battery cells that can be charged.

The Lithium ions inside the lithium cobalt oxide layer are designed by manufacturers so that only half of it is used, to ensure repeat charging and discharging for maximum cycles

Charging the phone while it is in aeroplane mode is indeed slightly faster, as all battery-hogging services like Bluetooth, cellular data, phone signal and Wi-Fi are off. The difference is minuscule, though.

The phone wastes a lot of battery power trying to find Wi-Fi services and connect with them when Wi-Fi is kept on in the background. 

It is a good idea to keep them off if possible and also reduce the screen brightness while you are at it.

An unofficial charger can be a bad choice for your premium phone as off-brand chargers may not meet the safety standards and could damage the battery.

The charger that came with the phone is your best bet.

Charging from the laptop is convenient and while the charging is slow, it is actually good for battery life as It puts less strain on the lithium ions.

Fast chargers save some time but may not be great for the phone battery.

There is no need to switch off the device to save the battery.

Modern batteries are designed to read their own level of charge at any time, accurately. If the device isn’t being used, the battery strain is minimal.

Cold weather does not adversely affect the battery, and actually makes it perform well. Exposure to hot weather for prolonged periods is what reduces battery life.

The phone may feel slightly slower in cold weather, and it is nothing to worry about.

Just keep in mind ...

Often the device charger is plugged in and kept on without any device. It is thought to waste energy, but the reality is that any modern charger with a brick attached to it has power-saving measures that keep the wire in standby mode, drawing very little energy. Even while in use, today’s charger...

We often think a complete discharge followed by a complete charge would be good for the battery. The truth is that charging when the battery level is at 50 percent will provide the least amount of strain to the battery.

Keeping the battery charge between 20 to 80 percent is the best way to ...

Placing the phone on an overnight charge is generally safe in modern devices, but it is not good news for your battery as it is at maximum strain when at 0 and 100 percent.

The battery limits set by the manufacturer will keep it on standby mode at 100 percent with the power being cut off, o...

A new battery can give your old phone a few more years of life, and most phone batteries can be replaced at home. Phone makers don’t want you to know this and prefer you keep buying newer devices from them every one or two years.
