There's no harm in keeping it on charge all the time. Unlike older rechargeables, newer Li-ion batteries don't need to be broken in by running them down and then recharging.
Have try to use another similar charger to charge it to see if it will charge? If you have and yet it did not charge, it means the charger is not the problem.
The problem is the the charging port, the charging port of your phone is bad that is why it is not charging, all you need do is to change the charging port of your phone and you will see that your phone will charge.
Replace the charging port and you will see that the phone will charge.
Have you try to use another charger to charge and it doesn't hold charge? if yes., no problem because it be that your charger is bad. But since it does not charge with another charger, it means the charging port is bad.
The problem with the phone is the charging port, the charging port of your phone is not charging the phone that is why it doesn't hold any charge,
All you need to do is to change the charging port of your phone and you will see that your phone will hold charge.
Hi,
The Li-ion battery cahrging circuitary is some what complex.
For most chargers, the charging procedure is divided into three main phases:
? Pre-charging phase
? Constant-current-charging phase
? Constant-voltage-charging phase
In the Pre-charging phase, it utilizes low charging current to protect the battery. However,in most recharging situations, the charged batteries still have some voltage remaining, so the charger does not need to apply this action, and just passes it on to the next charging phase.
The constant current and voltage charging phases are the main charging phase for
recharging the batteries, where most of the charging energy is transformed into the
battery. The maximum charging current for a battery depends on the battery?s rated
capacity. For example, one battery rated 700 mAh usually can be charged at 350 mAh to
400mA, for faster charging effort.
When the charged battery is Li-Ion, in the last charging procedure, the microcontroller
normally maintains regular charging voltage while monitoring charging current to
determine when the charging procedure should be completed.
When the battery is fully charged, most of the electrical energy is converted to thermal
energy, which can result in high battery temperature. In this case, the temperature
monitoring function will be added for the solution. But since most Li-Ion batteries on the
market also have an over-charging protection function, the temperature detect function is
rarely used.
So it is better to get your phone charging circuitary checked at a local store rather than to make a charger,coz both may cost you almost same.
all the best my friend.
