Cell phone batteries: the truth about extending their life

When your phone battery dies, it takes a piece of you with it. Or maybe that’s just us.
Whatever the case, phone, and by extension the batteries that run them, are an integral part of modern life. There’s a lot of misinformation out there about what does and doesn’t affect the health of your battery. We’re here to set the record straight.
In this article, we’ll be looking at cell phone batteries and the common “knowledge” that surrounds them. We’ll be looking at what’s fact and what’s fiction, and some of the best practices for protecting the battery that powers your smartphone.
|The myth||The truth|
|Overnight charging damages the battery||Not true|
|Occasionally draining your battery is beneficial||Not true|
|High temperatures damage batteries||True|
|The higher the mAh, the longer the life||Not necessarily|
|Third-party chargers damage your battery||Sometimes true|
|Ting Mobile charges less||Bit cheeky… true though|
Charging overnight damages the battery
Myth: One of the most prevalent in fact.
Some believe that plugging in your phone in overnight, or keeping your phone plugged in when it’s already at 100%, means power is being continually pumped through to the battery, overcharging it and reducing its capacity.
We get it. Overcharging was once a real concern. That was before smartphones became… well… as smart as they are today.
Modern smartphones manage charging much better. Once your battery reaches 100%, the charging stops.
So on the overcharging front, you can sleep easy.
That said, leaving your phone on all night, every night may have a slightly negative effect on the long-term health of your battery.
You see, charging your phone between 80% and 100% can place stress on your battery. So every time your phone drops below 100%, the charge needed to get it back up to full is slightly damaging your battery.
We wouldn’t worry about this too much though.
If you’re an Apple user, we’ve got a handy tip for you: Turn on Optimized Battery Charging under Battery Health, which will learn your daily charging routine and adapt accordingly. This should help address that stress.
Occasionally draining your battery is beneficial
Myth: Ignore this one.
This myth is a remnant of times before lithium-ion became the standard for cell phone batteries. While it’s true that in the past this would have helped your battery last longer, this technique will in fact likely do damage to your battery.
Just as charging between 80% and 100% places a bit of strain on the battery, so does charging in the bottom percentiles.
In an ideal world, to prolong your battery life, you want to keep your battery somewhere around the 25% to 80% region using partial charges.
High temperatures damage batteries
True: Definitely something to keep in mind
High temperatures can affect how effective cell phone batteries are over time. So, whenever possible, you want to avoid leaving your cell phone on or near hot surfaces, in direct sunlight or in a hot car.
We’re not saying that you should be panicking every time you’ve got your phone out on a sunny day, but you should just be wary about exposing your phone to high temperatures for prolonged periods. Think leaving it in the car, leaving it in direct sunlight, putting it in the oven for some odd reason. That kind of thing.
The higher the mAh, the longer the life
Not necessarily true: It’s definitely got the ring of truth, but there’s way more to it than just >mAh = >battery life.
Milliampere-hours or mAh, is the unit of measure for electrical charge. 1 mAh means one milliamp delivered for one hour. A 1 mAh battery discharges 1mA (one milliamp) for one hour and. A 10mAh battery provides 1mA for 10 hours. Get it?
So it seems logical that the higher the mAh, the longer the battery would last. Right?
If all phones were created equal then sure. They’re not.
The amount of power a phone consumes varies with a number of factors, from the processor to the screen size, the RAM and a bunch of other points.
So while the mAh rating tells you a battery’s capacity, it doesn’t do much to tell you how long it’ll actually last.
Android Authority wrote a great piece comparing the battery life of different phones with different sized batteries. It’s an interesting read.
Third-party chargers damage your battery
Not necessarily true: A few bad apples spoil the bunch
We saved this one to last because there’s some truth to it but again, it’s not that simple.
Ideally you want to be using the charger that came with the phone or a charger bought from the original equipment manufacturer (OEM). These, however, are often annoyingly expensive and so we wouldn’t blame you for wanting to shop around a little.
That said, exercise caution when trying to save a buck on phone chargers and cables. Chargers from reputable sources have built-in regulators that limit the amount of current being delivered to your device. Counterfeit or unbadged chargers and cables, on the other hand, may not.
This means that they could provide harmful amounts of current to your battery, potentially damaging it.
We’re not saying that you should avoid buying off-brand chargers completely. Just remember that if it seems to good to be true… well, you know how the saying goes.
