Battery difference 1 sim vs 2 sim models

[Tob]

Hi.

I'm still looking for a replacement of my Z1C, my question is simple.

Will the dual sim mode use more battery with only one sim compared vs the 1 sim model?

Thanks.

Hi @Tob,

Welcome to the community.

Dual SIM phones do technically use slightly more power than single SIM phones, as each SIM needs to check in with the network. This battery usage is not significant enough to be noticeable though.

Even only  using 1 chip?

@Tob,

Only when 2 SIMs are in the device. When using just one it will be the same as only one SIM is checking the network status, just like in a single SIM phone. Once again, this usage is minor and barely noticeable.

Thanks CameronT!

And also one of the sim will not be enabled for mobile data, which will save battery even more.
