It’s harder and more expensive to replace your phone’s lithium-ion battery than it is to treat it right in the first place. Many smartphones don’t provide easy user access to their batteries. That includes all iPhones and many flagship Android phones from brands such as Samsung. You should take better care of your phone’s batteries to assure its longevity.
Let’s investigate 4 major ways you damage your battery.
1). You don’t understand how your battery works.
You can’t help what you don’t understand. Not even your phone’s battery. After the first charge, your battery begins to degrade. Find out more about Lithium-ion batteries HERE.
What is really important here is how your battery charges and discharges. A complete charge cycle represents a charge from 0 to 100% for your battery. Let small incomplete charges represent only fractions of this cycle. For example, a charge from 50% to 100% represents half a cycle.
A lot of people use about 1 charge cycle a day. So, it depends on the user in particular. Battery manufacturers usually state that their batteries lifespan degrades by 20% after 400 cycles. In reality, it’s much less than that.
The obvious thing here is to reduce the number of changes you use. But you didn’t buy a phone to put it in a show glass. Balancing battery saving with utility is totally up to you. Go with whatever works for you.
2). Extreme temperatures.
Extreme heat or cold strain your battery. All batteries achieve optimum service life if used at 20°C or slightly below. If, for example, a battery operates at 30°C instead of a more moderate lower room temperature, the cycle life is reduced by 20 per cent. Leaving it in a car on a sunny day is a battery killer.
3). Fast charging
Charging your phone quickly always stresses your battery. Avoid fast charging like the plague. Unless of course its really urgent.
The slower you charge the better, I want to take a time out to debunk the popular myth that power banks damage your battery’s life.
This is very False, as long as the power bank voltage offered is between 5.1V to 5.4V( You can measure with a multimeter.) Read more Here. Charging with power banks or from your laptop limits the current hence, slows down charging.
4). Draining your phone battery to 0% or charging to 100%.
Your Battery is most strained close to 0% or near 100%. It is better balanced at around 50%. Keeping your battery around this point will require small, frequent charges. Carry around a power bank its or te greater good.
Also, When you want to store your phone for an extended period, charge it to 50% before turning it off and storing it. This is healthier for the battery than storing it at 100% or n to 0% before storage.
