How to Protect Your iPhone Battery Health in the First Place

That said, we have to conclude that in most cases, the battery is draining fast just because its health has been used up because other causes have a very limited impact on the battery life. And there is no going back or making up. Either you replace the iPhone or you replace the battery.

So how should we use our iPhone properly to substantially make the battery last as long as possible?

The basic rule to keep in mind: Never over-drain your iPhone battery or overcharge it whatsoever!

To do this, you are suggested to follow these guidelines:

Keep your iPhone in temperatures between 16 and 22 degrees celsius. Because both too hot or too cold temperatures would damage your lithium battery.

Avoid making your iPhone too hot for too long when charging or heavy using it (playing mobile games, watching videos, using maps, etc). When you feel the back of your iPhone is hot, try to cool it down for a while.

Always keep your battery percentage between 20% to 80%, because draining the battery at a lower percentage or from a full condition will damage the battery as well.


If your device’s battery is draining too fast, you can try using the solutions outlined in this article. While not all of the solutions will work for you, there is a high likelihood that you will be able to find a solution that alleviates your problem. It is important to note that if the problem is your battery, the above solutions may not work. If the iPhone battery has problems, you may have to purchase a new one.
