Battery Charger Bad Contact How To Do

  Battery Charger bad contact how to do

  Mobile phone in the charging process, will encounter some poor contact with the Battery Charger, some people will mistakenly believe that the reasons for the phone, when we phone does not charge the time, in fact, can change a Battery Charger for the phone to charge. Poor contact with the Battery Charger may be too bad metal contact, and lead to poor contact, you can take a clean cloth and paper wipe try, you can take a little cotton, or with a cotton swab dipped in a little alcohol, not too much, and then even Apply to the metal port of the Battery Charger port, wait for alcohol to evaporate naturally after the OK. If not enough, there are electronic basis friends can Xiaobian introduced the following way to try, the following together to see it!

  First, the Battery Charger bad contact how to do

  1, check is not outside the conductive film deformation caused by poor contact, if it is then directly adjust.

  2, if not the case of a check whether the internal desoldering, if any direct welding, if the coil is burned and other issues are not maintenance value.

  Second, the Battery Charger contact with the problem

  For a direct charge into the small 5 when the contact with a simple solution.

  Problem situation: 1, direct charge into the small 5 when the poor contact, just plug in a small 5 tips are charging, but then prompted to be removed to save the power and other words; 2, accidentally hit the line is charging, the results of small 5 It will be prompted to be removed to save electricity and other words, or a little move a small 5, then prompted to be removed to save electricity and other words.

  Solution: take a little cotton, or with a cotton swab dipped in a little alcohol, do not have too much, and then evenly applied in the direct charge into the small 5 small metal head, pay attention to do not put the alcohol into the hole. On the OK .I tried after the small 5 was charged, really no longer as easy as before prompted to be removed to save electricity and other words.

  In fact, the problem: plug in the Battery Charger, is the state of charge, and then charge to a minute will show poor Battery Charger contact. Can only pull the Battery Charger, and then charge it again. For several different data lines are like this.

  Reason: the direct charge of the output voltage is not enough or tail plug contact bad, mostly caused by voltage problems, not off the line thing.

  Poor Battery Charger contact

  Third, the mobile phone Battery Charger contact bad solution summary

  The phone encountered poor contact with the general situation of the maintenance program has the following:

  (1) do not disassemble the method,

  1. The following methods will not work, then it can only change the CPU

  2, first think about the Battery Charger is not original, generally not the original will be some problems, such as plug the touch screen can not touch, or charge intermittent. Replace the original on it.

  3. There may also be software problems, you can try to change a system.

  4, the phone after the shutdown, with the red line in turn touch the motherboard tail pin to see if there is a charging foot exists, find the future, with a soldering iron after the good, try not, if not continue;

  5. Replace the charge around the tail of a R104 exclusion try

  6. For the charge transistor test

  7, and then look at the Battery Charger head output voltage and current match with the original match, if the Battery Charger output is generally 350-400M, this is not up to the effect of charging the phone, replaced by the output of 550 --- 600MA Most can be resolved.
