您的手机电池会随着时间的推移而退化。当它发生时，即使电池指示灯显示(battery indicator)您还有充足的电量(juice left)，您也会发现手机正在关机。如果遇到这种情况，您需要重新校准 Android 手机的电池。
在这篇文章中，您将学习如何正确校准Samsung Galaxy S10、
Google Pixel或您拥有的任何Android 手机的电池。(Android phone)
检查电池
在校准电池之前，您需要先检查电池。取下手机的后面板以露出电池。将其从插槽中取出并寻找变质的迹象，如鼓胀或泄漏。
如果电池不再与插槽齐平，则该考虑购买新电池了。
市场上有不同的第三方电池销售商。但是，建议您坚持使用手机制造商(phone manufacturer)并购买原装。有些第三方产品未能达到预期。
校准损坏的电池会浪费时间。
注意：(Note:)当您使用它时，请查看充电端口和电缆(port and cables)。如果损坏，可能会导致您的手机无法满负荷充电。
耗尽电池的负面影响
校准手机电池的过程需要您将其完全耗尽。虽然这是一个必要的步骤，但如果经常这样做，这个过程会缩短电池的使用寿命。
完全耗尽电池不应该是一个长期的解决方案。
电池并不意味着耗尽为零。您的 Android 设备已采取措施防止这种情况发生。但是校准过程(calibration process)会让你强制 Android 完全耗尽电池。
但是，一些用户表示，如果需要，可以每三个月尝试一次校准。
如何校准Android 手机电池(Android Phone Battery)
正常使用手机，直到电池耗尽并且手机自行关闭。之后(Afterward)，将其打开并让手机再次自行关闭。这样做直到手机不再打开。
现在，无需打开它，将手机插入充电器并保持插入状态，直到电池电量指示器显示(battery level indicator)100% 充满。
取下充电器并打开手机。此时，电池指示灯(battery indicator)可能会自相矛盾，并表示手机未充满电。如果发生这种情况，只需重新插入充电器即可。这一次，请保持手机开机。
一旦达到100％，请继续拔下充电器，然后重新启动手机。重复此过程，直到手机在重启后显示已充满电。
完成后，再次耗尽电池电量，直至完全关闭。然后立即将其充电至满容量。
如果操作正确，这应该会校准手机的电池图标并更正
Android 设备(Android device)上的显示。
注意：(Note:)此过程也适用于平板电脑电池校准(battery calibration)。
根访问权限
通过root 访问(root access)校准电池还需要耗尽电池电量。只有这一次，您将在此过程中清除一个名为batterystats.bin的文件。
但是，某些用户不推荐此方法，因为它需要您下载第三方应用程序。也可以提出一个论点，即删除所述文件实际上并没有做任何事情。
在没有root访问权限的情况下耗尽电池并校准电池会更好。
How to Calibrate the Battery of Android Phones for Accurate Power Readings
Your phone
bаttery degrades over tіmе. And when it does, you’ll find your phone shutting
off even if the battery indicator says you still have plentу of juiсe left. If
it evеr comes to thаt, you need to recаlibrate the battery of your Android
phone.
In this post,
you’ll learn how to properly calibrate the battery of your Samsung Galaxy S10,
Google Pixel, or whatever Android phone you have.
Inspect
the Battery
Before
calibrating the battery, you would want to inspect the battery first. Remove
the back panel of your phone to reveal the battery. Remove it from its slot and
search for signs of deterioration like bulging or leaks.
If the battery
will not sit flush in its slot anymore, it’s time to consider buying a new one.
There are
different third-party battery sellers in the market. However, it’s recommended
that you stick with your phone manufacturer and buy an original. There are
third-party products that fail to live up to expectations.
Calibrating a
broken battery would be a waste of time.
Note: While you’re at it, take a
look at the charging port and cables. If it’s damaged, it could be causing your
phone to not charge at full capacity.
The
Negative Effects of Draining the Battery
The process of calibrating your phone’s battery requires you to drain it completely. While it’s a necessary step, this process shortens a battery’s lifespan if done frequently.
Fully draining
your battery should not be a long-term solution.
Batteries are not
meant to be drained to zero. Your Android device has measures in place to prevent
that from happening. But the calibration process will have you force Android to
fully deplete the battery.
Some users,
however, state that calibration can be attempted every three months if needed.
How
to Calibrate Android Phone Battery
Use your phone as normal until the battery runs out and the phone turns itself off. Afterward, turn it on and let the phone shut itself off again. Do this until the phone will not turn on anymore.
Now, without turning it on, plug your phone into a charger and keep it plugged in until the battery level indicator says it’s 100% full.
Remove the charger and turn the phone on. At this point, the battery indicator might contradict itself and say that the phone’s not fully charged. If this happens, just plug the charger back in. This time, keep the phone on.
Once it gets to 100%, go ahead and unplug the charger and then restart the phone. Repeat the process until the phone shows it’s fully charged after reboot.
Once done, drain
the battery once more until it shuts off completely. Then charge it right back
up to full capacity.
If done right,
this should calibrate your phone’s battery icon and correct the display on your
Android device.
Note: This process should also
work for tablet battery calibration.
Root
Access
Calibrating the
battery through root access also requires that the battery be drained. Only
this time, you’ll be clearing a file called batterystats.bin in the process.
This method,
however, isn’t recommended by some users because it requires that you download
a third-party app. An argument can also be made that removing the said file
doesn’t really do anything.
You’d be much
better off draining your battery and calibrating your battery without root
access.
