Default Easy way to save battery life on Verizon

Verizon, by default, uses Global mobile network. I switched it to CMDA/LTE/EVDo in the settings menu. That apparently turns off the global radio. It has improved my battery life considerably. Just a FYI.

even with decent use I'm getting between 12-14 hours out of this battery I think that superior compared to any other phone I've owned. I wonder how much more this really does improve it, maybe I could squeeze another few hours out of it.

It added about 4-6 hours for me on average, maybe more some days. Plus it is such a simple thing to change.

Based on your posting, I just checked mine and it's already set to CDMA/LTE/EVDO. But I don't remember changing it. Hmmmm.

Nice. I've had mine set to CDMA/LTE only for a while. I think I got 15 hours yesterday before I plugged it in and had maybe 30% left. And screen time was probably close to two hours.

I noticed no difference on the S3 and my S4 32gb came with the setting suggested here, out of box.

Battery life comparisons are too subjective, but an absolute way to maximize battery life is to leave data off and only use when you need it. Data activates instantly, so the button press is worth it. No point in letting the radio drain battery when not using it. Especially in weak signal areas. Like most devices like this, they drain battery the worst in weak signal areas. Turning data off fixes that and you still have phone and text function.

Agree re: weak signal areas. In general terms the lower the signal level in the downlink (cell site to device), the higher the transit power required in the uplink, therefore greater battery drain. I can't switch mobile data off as I receive a lot of push notifications, email etc. I do however minimise the use of the many other radios within the device; WiFi, Bluetooth and GPS are all switched on then off as necessary, this helps.

Good tip about turning off the global radio. I already get decent battery life but I'll try this tweak out and see if it improves. Thanks for the suggestion!

Hmm, interesting. I changed the setting to CDMA since I was changing a few settings as well. And today, my battery "seem" to last longer. This may be worth doing some test over. Interesting....
