7 common myths about the batteries in your favorite tech

1. Leaving a device plugged in will overcharge its battery: False

One of the most common lithium-ion battery charging myths is that plugging in your devices for long periods of time will overload the battery, wearing it out faster than usual. Don’t worry, it won’t. Your smart devices know better. Protective measures built into modern phones, tablets, and laptops ensure that lithium batteries stop charging once they reach capacity.

That said, if you leave your fully charged smartphone plugged in overnight, it’ll experience “trickle charge,” which means that as the battery naturally drops down to 99%, it uses a small amount of energy to bump it back up to 100%. This can cause the battery to wear out slightly faster, but not much faster than just regular use.

2. Freezing your phone battery helps keep its charge: False

Sudden, drastic shifts in temperature are never a good thing for your tech. Exposing your phone, tablet, or laptop to freezing temperatures can not only harm its battery, but also put other internal components at risk of malfunctioning. So never, ever put your devices in the freezer.

Tip: Charge your devices in a cool, ventilated place. Lithium-ion batteries don’t work well in freezing or overly hot temperatures, so avoid laying a stack of magazines on top of a charging phone or sticking it between some pillows, and don’t leave them in direct sunlight. Also, wireless and fast-charging devices can be helpful, but they produce lots of heat, so use them sparingly.

3.Closing Battery-Draining Apps Will Prolong Battery Life: False

In iOS devices, there’s a feature that allows you to close battery-draining apps. However, even if it is possible for an iOS user to turn off battery-draining applications at will, turning them back on again does not mean that the battery life has returned to normal. This option was created so users can get rid of unnecessary background processes and free up memory when they need it most.

4. Recharging battery-draining devices when they are at 20% will make them last longer: False

This battery myth is not true either! It has been proven that charging a battery with up to 80% won’t harm its lifespan or shorten battery life. And if you do need to recharge your battery when it’s still at 20%, you can use battery degradation mode, where your battery will be charged to 50% before stopping. This means that 60% of battery power is left unharmed and untouched during the charging process, which makes this option beneficial for battery health.

5. You need to let your battery hit zero before charging: False

Another cell phone battery charging myth is that you need to regularly drain the battery down to 0%, then charge it back up to 100%. This is true for older, nickel-based batteries, but not so for modern lithium batteries; the back-and-forth charging process will only wear down your device.

Tip: Try not to let your batteries drain down to 0%.

6. Your device’s batteries have a short lifespan: Somewhat false

There are several factors that go into how long your device’s lithium-ion battery will work as it should—how often you use your device and how often you charge it being two of the main ones. On average, you can expect your battery to last 2-3 years, or 300 to 500 charge cycles—whichever comes first. One charge cycle is measured from the time a battery is fully charged, completely drained, then charged back up again.

7. If your battery dies, you need a new device: False

If your device can’t last a full day on a single charge, or if it’s unexpectedly shutting down, your battery is probably starting to go. Other signs include lower speaker volume and sluggish apps. But a dead (or dying) battery doesn’t necessarily mean you have to invest in a new device. A battery replacement can be an affordable way to breathe new life into older tech.

A typical smartphone will only work at optimal capacity for 2-3 years before it starts deteriorating and becomes less efficient in performing basic tasks like taking photos or checking email messages without having power disruptions midway through the process.

But there are ways around this issue! You can replace batteries yourself if needed or get them replaced at a service centre. Here at BATTERYONE.CO we offer various batteries for your smartphones and other mobile devices.
