Yes, we know. No one is happy with smartphone batteries because they barely last a day. However, partly it is our fault.
Many of us have a deeply rooted belief that charging our smartphones in short intervals will cause long-term damage to their batteries, and that it is better to charge them when the battery is about to run out.
The site of the battery company CADEX (Battery University) reports that lithium‑ion batteries in our smartphones are sensitive to their own versions of “stress.” And just as with people, prolonged stress could permanently damage your smartphone’s battery.
If you want to keep your smartphone’s battery in excellent condition, you will need to change a few things.
Don’t leave it plugged in if it’s fully charged
According to the Battery University, leaving your phone plugged in when it is fully charged, perhaps one day after another, is bad for the battery in the long term.
Once your smartphone has reached 100% charge, it takes “trickle charges” to keep it at 100% while plugged in. It keeps the battery in a high-stress, high-voltage state, which wears down the chemistry inside.
Battery University has published a lot of scientific data that explains why, and at the end summarizes: “When fully charged, remove it from the charging device. It’s like muscle relaxation after intense exercise.” You wouldn’t be happy if you had to work nonstop for hours and hours.
Try not to charge it to 100 percent
According to Battery University, the “Li-ion battery does not need to be fully charged, nor do you need to do it. In reality, it is better not to charge it up to 100%, because the high voltage stresses the battery.”
It may seem contradictory if you are trying to have a smartphone that doesn't need charging all day, but you can simply plug it in for a short time whenever you can during the day, and you will be fine.
Connect your phone whenever you can
It is proven that the batteries of our smartphones are much more “happy”, if you can charge them intermittently during the day instead of plugging them in for a long charging period when they are empty.
When your phone's charge drops by 10% of its capacity according to Battery University, that would be the best time for a new charge. Obviously it's not practical for most of us, so you simply need to plug in your smartphone whenever you can. Don't be afraid, plug it in and unplug it many times throughout the day.
Thus, your smartphone's battery will have optimal performance for a much longer period, and it will always remain charged.
Additionally, you should remember that smartphone batteries are sensitive to cold and heat. Apple itself recommends protecting your iPhone when you charge it. If you are under a hot sun, keep your phone covered.
