What most iPhone users do not know is that there is a certain percentage of battery level when a phone should be recharged to maintain a healthy battery and prevent iPhone repair costs. The magic number is 80%. The 80% battery level isn’t just a randomly picked number but rather a combination of science and practicality. The percentage is a compromise between practicality and quality – a mix between being hasty and being careful. Understanding how a lithium-ion battery works and the way Apple designs their phone will save you on iPhone repair costs and will cut your trips to your trusted cell phone repair shop.
What Causes Problems with the iPhone Battery?
Before we dig into the reason why we came up with the magic number, let us discuss first what causes problems with the iPhone battery. There are a lot of factors that may be causing problems with your iPhone’s battery. Here are some:
- Factory quality issues. Though iPhones pass rigid quality checking to the point where Apple factory workers go on strike due to overly strict demands on quality control, there are still batches of batteries that may be of low quality. Though the chances of having a bad battery due to quality defect, we can still hear of reports about users returning their days-old iPhone due to battery issues. If you are having problems with your iPhone’s battery and you had just bought your device, you may still be covered with a free battery change warranty.
- The way an iPhone is handled may affect the phone’s battery. iPhones placed on tight containers and casings may put considerable pressure on the battery. Exposure to extreme pressure may be detrimental to the battery’s performance and health. Wrong handling of your iPhone may break other components that may require the attention of cell phone repair technicians. Fix cracked iphone screen
- The iPhone is made to be versatile. iPhones can play multi-media files, run productivity apps, play mobile games, surf the net, and open files and data. However, users should remember that iPhones are made for mobility and are not intended to replace some devices.

- Wrong battery charging practice. iPhones, like any other cellphone, must be charged most optimally. Wrong charging practices may make your trip to a cell phone repair shop sooner than expected.
Why Should iPhones be Charged at 80% Battery Percentage?
iPhones use lithium-ion polymer batteries. A lithium-ion battery’s life is measured by charge cycle. Charge cycles are completed once you have consumed an equivalent of 100% of battery power. One charge cycle is used by a phone running six straight hours until it was drained use. The same phone using 25% of its power on the first day, 25% on the second day, and another 50% on the third day would have completed a charge cycle.
If a charge cycle is just but a consumption of 100% of battery power, then what’s the sense of charging the battery at a certain power level? The question may have popped up in your mind.
The answer lies on how Apple, and most smartphone companies, designs its phone; and lithium-ion batteries react to types of charging.
When charged quickly, there is a high electric current activity in the battery. This allows batteries to charge quickly. However, during fast charging, the instability of the electrical current causes a battery’s life to shorten. Replace iphone 7 screen. On the other hand, slowly charging lithium-ion batteries (trickle charge) will allow the electrical current to relax and stabilize causing longer battery lifespan.
Phone developers are now faced with a dilemma. Allowing quick charging on phones will quickly decrease a battery’s useful life. However, users are never happy to be tied to the walls for hours. To balance the pros and cons of quick charging, phone manufacturers have decided to go with the 80:20 battery charging rule – quick charging until 80% to give users a quick boost in their battery power; and slow charging from 81% to 100% levels to extend a phone’s battery life.
iPhone will do a quick charge when it is below 80% level and will charge slowly at more than 80%. Lithium-ion batteries that are charged slowly tend to have a longer life than those that are charged quickly.
You just learned why it is advisable that you recharge your iPhone when the battery level goes below 80%. Please share this article with those people who may be interested in the topic.
