No one is happy with them batteries of smartphones because they barely last a day. But it is partly our fault.
Many of us have a deeply rooted perception that charging our smartphones at short intervals will cause long-term damage to their batteries and that it's best to charge them when the battery runs out.
The site of the battery company CADEX (Battery University), states that the lithium-ion batteries on our smartphones are sensitive to their own versions of “stress.” And as with humans, this could destroy your smartphone battery in the long run.
If you want to keep your smartphone battery in excellent condition you will have to change some habits.
Do not leave it plugged in if it is fully charged
According to CADEX, leaving your phone plugged in when fully charged damages the battery in the long run.
Once your smartphone has reached 100% it takes “trickle charges” to stay at 100% while plugged in. It keeps the battery under high stress, which wears down the battery chemistry.
The Battery University has published a bunch of scientific evidence explaining why, and at the end it summarizes: “When fully charged, remove your phone from the charger. It's like relaxing muscles after intense exercise.”
Try not to charge it up to 100 percent
According to Battery University, the “Li-ion battery does not need to be fully charged, nor should you. In fact, it is better not to charge it to 100% because the high voltage stresses the battery.”
The above seems contradictory and unwieldy, especially if the mobile battery does not last for the whole day, and you have to plug it into the socket several times during the duration of the day.
Connect your phone whenever you can
It turns out that our smartphone batteries are much happier if you can charge them intermittently throughout the day instead of plugging them in for a long charging period when they're empty.
When your phone charge has lost 10% of its charge according to Battery University then it would be the best time to charge again. Obviously not practical for most of us. The message is, however, don't be afraid to connect and disconnect your mobile several times during the day.
So your smartphone battery will perform optimally for a much longer period of time.
In addition, you should remember that the smartphone's batteries are sensitive to cold and heat. Apple itself proposes to protect your iPhone when you charge it. If you are under hot sun, keep your phone covered.
