Absolutely every Li-On have protection circuitry and that protects from overcharging. When battery reaches full charge, phone turns to maintenance mode and stops charging battery. Maintenance power keeps phone alive without charging the battery. In the morning battery is 100%. Our question is Why to force battery stay full? Yes, you get 100% full battery and next 30min it is near 90%.
Our solution is: we want to offer a BRIGHT new style of charging
Slower the charging, stop before “full”, prevent the “forcing” and then shut down the charging always completely.
Comes with values:
*Improved safety - no overheating risk to charger or battery
*Energy efficiency - Save energy because cut of idle power of charger and maintenance/forcing power to battery
*Better battery - Might increase time between the charging sessions and battery life
*Optional night light feature + clear indicator to charging status
*slower charging:
Talking about 1A vs 2A charging, which is fast. 3A is even faster. On the other hand, fast=heat. Repetitive heating and even overheating is bad for lithium ion batteries. Compared to fast charging, you always need that same charger, which makes the “handshake” with your device for giving the fast charge to your phone. When the handshake is done / approved, the fast charge starts: the more Volts it can give the more Amperes which speeds up the charging. Simultaneously, charging chip has to monitor battery temperature because it rises a lot and has to be under threshold. It means if you open the phone and start using it, charger’s boost charging, temperature rising and fast charging have to stop. Playing with this temperature threshold and overheating is something we don’t want to recommend, because of studies on fast charging suggest there’s a possibility that it might reduce time between charging sessions and thus your battery life. Our thinking is based on a fact: Heat and Li-On don’t fit together.
*Improved safety:
Chargers can cause risk of fire. Visit Google “fires caused because of chargers”. BrightCharger has the value of taking off risk of fires caused by chargers and this value works with any kind of USB chargeable devices. Our way is we separate the battery from the charger as well as unplug charger from the wall after we’ve fulfilled the battery. Without an effort to think you get safety that haven’t been possible to provide before as simple way.
*Energy efficiency
Energy savings which is achieved when shut down charging and charger automatically, without effort to think.
Saving isn’t much to individual but if we reach bigger picture the numbers grow. We think it is just irrational that all the world’s chargers consume while in a wall, even when not used for charging or for the phones’ landline modes. When battery reach full it’s turn to maintenance mode and in these modern days we don’t want to go back and turn our mobile gadgets into landline devices when battery is full. Talking about savings based on this ‘landline phone function’, e.g. Samsung Galaxy S7 edge consumes 4,8W in that mode and with certain cycle ‘sniffs’ if the phone’s battery needs to be fulfilled again and again. That is only way how you can get 100% full battery in the morning. Our way is we separate the battery from the charger as well as unplug charger from the wall after we’ve fulfilled the battery with slower charging to “full”. So number of consuming is pure zero after charging is stopped (and night light switch is OFF) Then we have zero consumption and not possible to charge again before touching the dome of the charger.
If Optional night light mode ON, then after charging process is ended, the consumption of LED is 1.4W
*Better battery:
There is always some kinds of treadmills ongoing all the time and that is only way keep battery full 100% and that we want to stop.
One fact is anyway Li-On best working range is 10-90% and everybody knows that, unplug that 100% full battery and see how battery drop quite fast near 90% and then it start to last better. So we think at is best for the battery to charge above 90% then stop the charging. Check out battery university long-term studies about this topic (

*Finally
We’re more than happy to tell that actually there is a solution determining the status of the battery and we do it with our algorithm. BrightCharger is able to make the decision when the battery is “fully” charged. (90-100%) Include situations when phone is resting or someone is gaming with it. BrightCharger stops charging completely and stops drawing power from the wall. To re-charge, it requires touching of the dome again.
