Hi guys,

So I got my first dual SIM phone. Now I know that having two SIMs will drain the battery more, I've read about 30% less usage than a single SIM phone.

Now, if I have only one SIM in, is the component that looks for signal for the second SIM powered on? I have the other SIM disabled in the settings. From my battery drain it would seem so. Just wondering. Most of the battery is going to phone idle and mobile standby. I lost 12% in 8 hours while I slept. Screen was off all the time, internet and wifi also off.

I expect about 3% do go in 8 hours of sleeping. Not 12%. :mad:
 
Like now, already 21% gone with only 24 minutes of screen on. Most of that time I was sleeping.

The next picture shows last night. 7% gone on only airplane mode, no awake, no internet or wifi.

Mobile standby en phone idle just seems to much to me. I compare this against my SII that ran a CyanFox, also an almost stock OS.

Have an Acer Liquid E2 Duo Sim
There is a Cell C and Vodacom sim in the slots and I find no difference in power usage when only one sim is in or active
Battery last for 2 days with a night time switch off
 
On my S2 I had a big problem with phone idle using most of the battery.

Did a factory reset and it was fixed. Phone idle now hardly uses any power.

Maybe its a faulty unit? This is the Moto G right?

Yeah the Moto G. I don't know, it could just be a software issue.

That sounds better. Interesting that you say you don't find a difference in power usage. There should be. That means that both SIMs are drawing power, even when one is off :confused:

I read that after the Kit Kat update, users across different phones were experiencing issues with battery drain, loss of signal etc. When I got the phone, it updated to Kit Kat and I did not reset it after I did the update. With all of my previous Android phone, I reset the phone after a major update to give it a nice clean start. So I did that tonight and I'm leaving the phone now, will report back tomorrow.
