难以充电

emusician

用了两年的S3，最近突然无法通过插头充电，就连power bank也不能充（都是用原装cable），只有通过连接电脑才能充电，非常麻烦。
请问这样情况是什么问题？电池或手机？

usb port有问题了

哦，是说插头和power bank的USB port？

不是，手机的usb port，附焊在电板那个

如果是这个坏了，是没得修咯？或不值得修？

S3充电的问题很多时候是由于“不稳定电流”造成的
根本的原因可能是 Cable, Power Bank, Charger的问题

如果不要换 Cable, Power Bank, Charger, 可以试试用 Custom Kernel => Ignore Unstable Power


我试过,有效, 烂Cable, Cheap Power Bank, Charger在默认情况下充电很慢,
Set了Ignore Unstable Power后,可以跟正常的一样.
正品的 米电, yoobao Power Bank + Cable 不需要设置,也非常稳定的充电在1A
Set了1000mA, 电脑USB接口也很稳定1A Charging, 2小时可充90%++

可以使用这个软件来检查充电电流

7.5 Ignore unstable power

Default: Off

Expected impact: Faster loading workaround for faulty charger devices

There are many faulty chargers around, that are not able to provide a stable charging current to the device. A prominent example is for instance the Samsung stock charger delivered with the Galaxy S3. In the Galaxy S3, the charging logic recognizes unstable power and reduces the charging current in 100 mA steps until it detects the power to become stable. Then it deducts another 100 mA as a safety margin to be in a controlled situation (also see below the "ignore safety margin feature")
This causes sometimes extremely long loading times as in fact the load cycle is performed with only 400 or 500 mA.
This switch disables this logic on your own risk. So even if the charger cannot supply a stable power, the charging logic will not reduce the current back.
This setting might damage your charger long-term, but for the majority of the users it just fixes the problem. Use at your own risk !!!

哇，好像很复杂.....
但还是多谢你的答复。
