Your battery is probably fully charged and the brief flash of the icon is just the charger "topping it off".
There is nothing to fix, as nothing is wrong about this charging behaviour.
Boost charging involves a high current for short period of time to charge the battery. It is generally if the battery has been discharged heavily. Boost charge enables the quick charging of depleted batteries.
It's in the amount of current that is used to charge the battery. If the amp-hour (Ah) capacity of the battery is known, charging at the 5-hour rate or quicker would count as a boost charge, while charging at the 20-hour rate or slower would be a trickle charge. So for a 40 Ah battery, a boost charge is more than 8 amps while a trickle charge is less than 2 amps. A normal charge would be 4 amps.

Charging a battery at 2 amps means it will receive a constant current of 2 amps over time. The charge is not cumulative, as the battery will only receive a 2 amp charge until it reaches full capacity or charging stops.
You simply cannot as it is THE battery that you are charging...
The battery is probably dead.
How long should I leave a battery on charge
No, the charge in the battery is a change in state of the battery contents, not an addition to the battery.
Rechargeable batteries are generally stored and shipped with no charge. This allows for a longer battery life. Fully charging the battery the first time will give you the best results for maximum charge and battery life.
It has to do with your battery charge. it's either charging or is at full charge.
Can You Charge...Yes. As a matter of fact, in order to charge a battery, the charging voltage HAS to be greater than the charged battery's voltage or no current will flow and charging cannot happen.Of course, the charging voltage cannot be excessive, or damage to the battery being charged will result.In your question, 4.6 volts is not excessive for a 4.2 volt battery.
The tracker must be removed from the wristband The tracker is inserted into the charging cable The charging cable is inserted into a UL-certified wall outlet or a USB port on a computer The LED lights will pulse every few seconds will shows your level of battery charge
