Battery life with Elisa vs Telia
With my usage pattern the battery life of my XperiaX has usually been ~36 hours (recharge every second night). Recently that has shortened so, that I have had to charge almost every night.
A couple of weeks ago my employer (I have company SIM) decided to change the operator from Elisa to Telia. To my surprise the battery lasts now easily over two days/nights !?
What could explain this ? I live in a capital area of Finland, so Elisa should have strong (4G) network here.
