[G4 General] One Twelve:
xposed requires recovery. recovery requires an unlocked bootloader. The euro h815 is the only G4 variant in the world that presently allows to unlock the bootloader. There are ways to get around this but i don't know more.

better and safer to get things working properly in stock before trying other ways.

If you're at 50% you should be averaging closer to 4h on data and 5h on wifi. This is provided you are static and have a good signal with moderate use. You should get at least a good hour+ more than people running at 100%. That is provided you aren't running extra things in the background. Hotspot, satnav etc are going to knock those figures down.

Global is if you travel abroad or if your carrier also uses GSM networks. if that is not the case then LTE/CDMA is the setting to use. It wont be searching for GSM networks that aren't there.

Did not know verizon ran in california, thought Cali was at&t country.

ok, advanced calling uses volte. Turning off volte turns of advanced calling. What happens if you get a call after turning off volte and you are on data ? does it disconnect data and transfer over to voice.

4 g can handle voice & data and provided you have a good signal you should get better battery life.

Driving means radio has to keep up with different cells, if its doing hotspot on top then that's extra work. Long distances means 4g may or may not be availble so it will be constantly switching between 3g/4g on the route. You want it hooked up to power in such a situation.

So if we strike hotopot off the list, what kind of sot do you get at 50% brightness in a borderline cell reception area ?

There is an added issue of carrier bloatware. Have you disabled any of it yet.

Is there a CDMA only option ? That should do 1x & 3g.

It means you have to manage it, when you enter a 4g area you have to manually switch over to LTE. Experiment with this as it might be fiddly to get back to 4g when you want it.

Not a great signal for data. its ok for voice or messaging but data is more demanding particularly the higher g's. What does 4G show ?

To give you an idea what those figures mean. a 3 dbm difference means a doubling or halving depending on the direction you're going.

So 100 is half the strength of 97 which is half the strength of 94 which is again half as strong as 91 dbm. So 100 is eight times weaker than 91. Guess what that means for your cell radio. Its got to amplify that signal and use power to do it.

If you don't use data all the time best is to stick to cdma as that carries further and switch on data only when required.

Either mifi or a even a portable one with a good batery ie 3000mah.

A cell signal booster for the house is another option. if you can get that signal to high 80s or low 90s you will be good. People that push over 5hrs sot on data get signals that strong. They also never use wifi so that's one extra radio that does not have to run. No need if you get such a good signal.

what was your previous phone and how much sot did you get with it. Set some baseline for expectations.

It could be the os just indexing the card, did you move a lot of files over to it recently ?

or it could mean a card with read errors. If you are using a new class 10 card there should not be any issue.

The mediaserver intem in your battery usage stats did not seem out of the ordinary if it was doing work with the card.
