Do all optimus’es have them ?? Update (08/25/2019) as far as i know,these lg models have an rtc battery: optimus g. optimus L9. g4. g3. g2. f6. xpression. phones still need an rtc battery for when their main battery is out & it won’t have a network to get time from when it turns on again.
No, cell phones sync time with the cellular network they associate with.
@lgb470 no, it does not. Let us know where you got the information about those LG phones you listed as having an RTC. I’d like to double check that info.
