I've noticed the same. I get the impression that the stronger the network signal, the better the battery lasts - I assume because the radio has to increase the power with which it communicates with the tower when the signal is weak.
- kabouseng 12y agoCorrect, the GSM modem do indeed vary its transmission power depending on the RSSI (received signal strength). Also with low signal strength packets get dropped, so needs to be retransmitted, which also drains the battery more.
- antoaravinth 12y agoThis is interesting, do you have any resource on this topic? I wonder how a phone with dual sim can handle battery life? Thats totally an interesting problem to solve. I use micromax which is a dual sim and the battery life is pretty good, last for a day.
- s_kilk 12y agoWhich may account for the wild variance in reported battery life from different people with the same model of phone.
- exelius 12y agoCan verify this. I was working for a client who was located in an area that had maybe 1 or 2 bars of LTE service - my phone was below 20% at the end of the day if I didn't charge it. Now that I'm in a big building with AT&T microcells, I get 5 bars LTE so my phone is at over 50% by the end of the work day.
- 0x0 12y agoYep, and it's very obvious even in different parts of the city for me. In one office, the phone is still at 60-70% after a day's work, while in another it's usually dead by the end of the work day.
