Takeaways

• 😀 Fast and wireless charging may not be as damaging to your phone battery as once thought, especially with modern chargers like those from Anker.
• 😀 Charging a phone overnight to 100% may not be the best practice for battery health, as it causes stress on the battery over time.
• 😀 The last 5% of charging from 95% to 100% takes significantly more voltage with very little current, which stresses the battery.
• 😀 Keeping a phone at 100% charge for long periods is uncomfortable for the battery, which can lead to premature aging.
• 😀 To extend battery life, it's better to stop charging once your phone reaches around 60-65%—this keeps the battery in a less stressful voltage range.
• 😀 Fast charging works best when the battery is under 50-70% because it's still able to accept ions without creating excess heat.
• 😀 If you want your phone to last longer, aim to keep the charge between 25% and 80% rather than fully charging it each time.
• 😀 Wireless chargers can be a great option for maintaining battery health, as they allow for more frequent top-ups without overcharging.
• 😀 Active cooling in wireless chargers helps with faster and more efficient charging, reducing heat and preserving battery health.
• 😀 iFixit's Pro Tech Toolkit is a great option for DIY phone repairs, providing all the necessary tools with a lifetime warranty.

Q & A

Why is there a concern about fast and wireless charging for phone batteries?

The concern mainly stems from heat generation during charging. Excess heat can damage the battery, potentially leading to premature wear or reduced capacity. However, modern chargers have reduced this risk significantly.

How does the charging process affect battery health when reaching full capacity?

As the battery nears 100%, it becomes harder for it to accept charge. The last 5% of charging requires more voltage with less current flow, which can generate heat and cause unwanted chemical reactions in the battery, leading to long-term damage.

What is polarization, and why is it a concern during charging?

Polarization occurs when a battery mistakenly believes it's fully charged, even though it isn't. This can happen when charging too quickly near full capacity and can lead to inefficiency and potential damage over time.

Is it okay to leave a phone plugged in overnight to charge?

Leaving a phone plugged in overnight isn't ideal if you're aiming to preserve battery health long-term. Keeping the battery at 100% for extended periods can stress the battery and reduce its lifespan.

What is the ideal voltage for maintaining a healthy battery?

To prolong battery life, it's recommended to charge your phone to around 60-65%, keeping the battery's voltage around 3.9V, which is less stressful for the battery compared to charging it all the way to 100%.

Why is it suggested to keep the battery charge between 25% and 80%?

Charging within this range reduces stress on the battery and helps preserve its capacity. Batteries tend to degrade faster when they are constantly charged to 100% or discharged to 0%.

How does fast charging affect battery health?

Fast charging is beneficial when the battery is below 50-70%, as it allows for a quicker charge without significant heat buildup. However, it should be avoided when the battery is nearly full, as it generates excess heat that can harm the battery.

Can wireless charging help preserve battery health?

Yes, wireless charging can help maintain battery health by allowing the battery to 'graze' rather than 'gorge.' By using wireless chargers throughout the day, you can keep the battery charge within the optimal range without overcharging.

What makes a good wireless charger for preserving battery health?

A good wireless charger should have active cooling to prevent heat buildup and ensure efficient power delivery. It should also align the phone properly to optimize charging efficiency and reduce wasted energy.

What are some alternatives for people who want to maximize battery life?

For those seeking to maximize battery life, charging in small intervals (keeping it between 25% and 80%) and using wireless chargers can help. Also, avoiding deep discharges and overcharging, as well as using fast charging only when the battery is low, are important practices.
