From iPhone 12 would lose between 20 and 30 percent battery life overnight. Normally, the battery charge of iPhones decreases by about 5 percent during the night.
Users reported several problems with the battery life of the new iPhones on internet forums. Some iPhone 12 owners say that the battery runs out relatively quickly even with normal use.
According to some users, the battery problems lie with the wireless connections because they did not occur when the iPhone was put in airplane mode at night. Tests would also have shown that there seems to be nothing wrong with the batteries themselves.
5G
A possible cause is the support of the faster 5G networks, which is new in the iPhone 12. Connections with 5G often consume a little more power, which could be the cause of the shorter battery life. But many users do not yet have access to 5G networks.

Dualsim
Another cause could be the use of dualsim. With dualsim, a phone uses two SIM cards (possibly also virtual with one Yes it is). This means that the device must remain connected to two networks. However, the iPhone 12 is not the first iPhone with this option.
Apple has not yet responded to the matter.
