我的uvk6在刷过一次非官方固件后，重新刷回原产固件出现了电池电压显示不准确的现象，并且此过程中未进行拆机等操作。请问各位前辈如何对显示电压进行校准？

跟那个备份校准文件是否有关？

刷第三方固件前，是否备份校准文件？备份了，那就刷校准文件，即可解决没备份，那就放弃吧。网上去找和你主板型号一致的校准文件，刷官方固件，然后恢复校准

万用表量背面的两个金属触点，进入菜单50电池调压，调为万用表显示的数值就可以了。校准文件对电压不起作用

@"BG4JFQ"#p22580 校准电压原来是这么用呀，学习了！另外，请问校准电压的作用，是不是让剩余电量显示更准确？

@"BA4QDP"#p22607 是的，我也是刚玩，校准后不会出现低于30%很快没电的情况，从100%慢慢掉电。今天测试了一下，最后4%的电量，待机半天，最后0%自动关机。

貌似没找到原厂固件如何校准，只有第三方估计有校准功能

How to calibrate the battery voltage using the original UVK6 firmware?

BD3QGV

After flashing my UVK6 with an unofficial firmware and then reverting to the original firmware, I noticed that the battery voltage display was inaccurate. This happened without any disassembly or other modifications. Could you please advise on how to calibrate the voltage display?

Is it related to that backup calibration file?

BG9JFN

Before flashing a third-party firmware, should I back up the calibration files?
I've backed it up, so let's just flash the calibration file to fix it.
If you don't have a backup, then give up. Find and download calibration files that match your motherboard model online, flash the official firmware, and then restore the calibration.

BG4JFQ

The two metal contacts on the back of the multimeter should be inserted into menu option 50 (battery adjustment). Adjust it to match the value displayed on the multimeter.
The calibration file does not affect the voltage.

BG4JFQ I learned how to use the calibration voltage this way!

Additionally, could you please explain the purpose of the calibration voltage? Is it to make the remaining battery level display more accurate?

BG4JFQ

BA4QDP Yes, I just started using it too. After calibration, it doesn't drain below 30% very quickly. It gradually drains from 100%. Today, I tested it and when the battery was at around 4%, it remained on standby for half a day before automatically shutting off at 0%.

It seems that the original firmware cannot be calibrated, and only third-party options are available for calibration.
