70% of iPhone Users Don't Know Battery Care and Replacement Tips

If your iPhone shuts down or restarts automatically when the battery is at 10% to 20%, this is caused by the battery, indicating that it needs to be replaced. So how do we determine the health of the battery?

1. Check for phantom power phenomenon (if it shuts down at around 10%, it indicates phantom power). If your battery is healthy, it won't shut down even at 2%.

2. Turn on airplane mode and also turn off Wi-Fi, observe the standby time. If it can't last a day, it indicates your battery is really failing.

3. There are software available on the market that can check battery health (I won't mention the name), which can show the number of charge cycles.

4. For iOS version 10.2.1 and above, go to Settings – Battery. If there is a battery issue, the iPhone will prompt you, but I haven't seen any phones with such a prompt yet.

If you have the above situations, it indicates that your phone's battery needs to be replaced. You can go to Apple after-sales service for replacement, with some models priced at 600 yuan each. Of course, you can also buy a battery yourself for replacement, which is more cost-effective.

So how can you slow down the battery degradation of your phone?

Some friends like to keep their phones plugged in all the time; this habit should be corrected, as it can damage the phone and waste battery. We should try to unplug the charger once the phone is fully charged and try to let the battery drain completely while using the phone. For those who drive, buying a good car charger is important, as some car chargers or USB ports can easily damage the battery. My iPhone 6's battery was damaged within six months due to poor charging. Unplug the charger once it reaches 100% and avoid keeping it plugged in. Of course, for the wealthy, it doesn't matter; they can just replace the phone when the battery is dead. A more important point is to use a 1A charger, as it is slower but better for battery maintenance. That's all for today!
