IPhone users who switched to Samsung Galaxy?

So, I've been an iPhone user the past few years, but the 5 is just such a disappointment. I've had three 5's now and they've all had the same battery drain issues and it just seems like the iPhone isn't really evolving and they don't update their software enough. I love how safe the app store is and I like using iTunes for everything, but it's not customizable and the jailbreaks slow it down.
I'm strongly considering the Galaxy for my next upgrade but really have no idea what's better about it other than being able to customize it and the larger screen (<3). I was hoping to find some iPhone users who switched and have no regrets.

I wonder how safe is the online/app Mint? They want my bank account?

The online app actually says it will transfer transactions to the app… But I'm so afraid of giving my info. I'm just looking for an app that will allow me to input a budget and help me with that budget. We use the Dave Ramsey way of doing things… Like envelopes, etc. My hubby did have our budget on a word document and so it would show us when different accounts would be paid off. I'm looking for a program/app for my macbook/iphone that is much like this. Any advice?

Tesco broadband. Can I get a stronger Wi-Fi signal?

I have Tesco unlimited broadband. It works fine but was wondering if anyone else has trouble with a weak signal when you are say 10-15 meters away through a couple of walls?

My laptop picks up 2 out of 5 bars in signal but my iPhone 5 gets nothing at all.

Could I upgrade my router? And if so, what would be a good one? Is there such a thing as a signal strength chart or anything like that? Just thought I'd ask.

Is anyone else experiencing usage issues with the iPhone 5?

Which only occurs when the 4G is on, even when the 4G is turned off the usage goes up per minute, even when no apps are running in the background and Wi-Fi, email, bluetooth, location services and iCloud isn't on.

However, I do have some notifications on such as phone and messages which is a necessity when utilizing the device. Only way to stop it is to turn it off and on again. Don't want to do a restore, make a "genius" appointment, talk to "apple care" or do a hard reboot.

Maybe apple can do another update to the software? Especially others seem to be experiencing odd behavior with it. If anyone else is encountering this issue please respond.

Added (1). For the record, the data doesn't go up - never stated it anything about having a problem with it. Specifically stated it's the USAGE. For instance. You when the usage and standby are both at 0 after a full charge?

when 4G is turned on the usage and standby are equal after a couple hours, even when not being used.
