At present, many customers think that using new technology battery/spot welding is the only way to solve pop-up message, but do we really understand the difference between them? Well, please follow my footsteps and learn more about their differences!!!!
How it works?
New Technology Battery: 1.Don’t need to do spot-welding / 2.Automatic battery programming.
Spot Welding Battery: Battery Cell+ older original BMS to do spot-welding.
Through these two pictures, we have a rough understanding of the two methods of replacing the battery. But to give you a deeper understanding, here are the advantages and disadvantages of new technology battery compared to spot welding battery.
New Technology Battery:
Advantage
1. No spot welding is required, no professional welding equipment or personnel is required, only scissors arency needed, very high efficiency.
2.The new BMS is accurately measuredand can fully use all the capacity of the battery core.
3.Real battery health, not fake data.
Disadvantage
Due to the relatively complex process, the cost of this battery will be higher than battery cell + spot-welding(attery cell spot-welding,there only the cost of battery cells).
Spot Welding Battery:
Advantage
1.Lower cost needs. (The cost only battery cell withou BMS flex)
Disadvantage
1.Require spot-welding machine.
2.Require some phone repair experienced .
3.The capacity may not fully use if Older original BMS is over times used.(This will be explained in detail below.)
Why we can’t use the full battery capacity after we spot welding the battery ? But Why the New Technology can use the battery full capacity?
As far as we know , Apple double-encrypts the chips in its models, the underlying data cannot be written. For models below IPhone 11, We can directly modify the underlying code to match the battery cell, and it also dismiss the non-original message.
This is why when the battery exceeds the number of charges, the voltage will be limited.(This will be explained in detail below.)
Data Information:
For example,
IP11/12 series standard limit voltage is 4.45V.
IP13/14 series standard limit voltage is 4.47V.
When the charging times and battery cycles times reaches to a number , like 300 times, 500 times, 1000 times,the battery BMS will forcibly reduce the fully charged voltage to prevent battery damage due to overcharging.
(that’s the reason why apple will remind us to change a new battery when the battery healthy is lower than 80%)
So when the battery old original BMS have already over-used in the last battery,it’ll limit the actual usage capacity of new battery cell to varying degrees.
When the older original BMS flex charging times more than 300 times , capacity loss is around 7%
When the older original BMS flex charging times more than 1000 times, Capacity loss is around 13%
New Technology Battery: The old BMS is only used for booting and does not directly participate in the work. The data is all operated by the new BMS with a cycle count of 0, so it can use the full battery cell capacity.
Spot Welding Battery: The BMS is still keep high cycles number, so it can’t use the full battery cell capacity.
