Do anyone know of a tweak where when i use a LTE/3g connection for certain app like youtube and safari, it will notify me or ask me for permission just that one time untill i hit the sleep button on phone. Reason is, i sometime turn off wifi on my iphone when i leave the house and when i return home, i forgot to turn wifi back on and accidentally use my data plan connection.

P.S does turning off wifi save a significant amount of battery life ? I'm guessing if you leave it on, it will always searching for hotspot.

settings -> wifi -> turn off ask to join networks

and it won't constantly be searching for wifi
i don't notice any signs of battery improvements by enabling/disabling wifi

i do notice battery improvement when enabling airplane mode and then turning on wifi when i'm in an area with "no signal" or "really bad signal" though
 
Like Darrick said above I never turn wifi off. It doesnt save any extra battery even worth mentioning.
It will not search for wifi if you have that option disabled "turn off ask to join networks"
It will just autojoin known wifi's when in range.
 
Not sure if I'm remembering wrong, but someone mentioned it being worth turning off Cellular Data and LTE when connected to WiFi and still be able to receive SMS and stuff (not iMessages) here.
Doesn't seem to make sense, but would think this would help on battery. Anyone know if this is true?

It would help to disable LTE but not so for cellular data. Disabling cellular data just tells your phone not to use data. Your phone will still be using battery to connect to 4G (for voice and texts and such)

cool to know thanks. I'll disable LTE then. It's slower than 4G anyways right?

You can disable LTE or cellular data and still get calls and texts (and data from WiFi if you are connected).

I thought I heard that. Wonder if it's worth it when on WiFi? I figure you could miss texts and calls and prolly even MMS messages.

Disabling LTE will give noticeably battery life but that won't be so with cellular data if you're on wifi

You won't miss texts and calls if you disable cellular data but you WILL miss MMS if you disable cellular data

Thats cool to know that disabling LTE is noticeable battery improvement.
Anyone know if Actlf would work for auto disabling/enabling LTE?
I'm just unsure if the phone locking would effect this tweak and cause it to turn off an on each time at Lockscreen when answering a SMS with Bite. Seems like that could drain the battery.

I'm not sure that disabling LTE would end up with better battery life just on its own. If you have marginal LTE signal or something like that, then perhaps, but otherwise I'm not sure it would do much and perhaps might be worse in some sense (comparing power consumption of various forms/speeds of 3G vs LTE).

the reason why LTE wastes more battery is not because the technology itself is a battery hog

it's slightly better than 4G in terms of power consumption but the reason why it sucks up more battery is because there's no VoLTE. so that means even when you connect to LTE for data, your phone is still connecting to 4G/EDGE/GPRS for voice/texts. so you're essentially using twice the battery with LTE enabled

that's why when you get a call coming in, your phone instantly falls back to 4G without any hiccup and when the call ends, it takes a while before you reconnect back to LTE. Texts are also sent via 4G as well. LTE was originally only designed for data usage only and so all the protocols and such aren't compatible with the ones we've currently been using

If you're ever in a rare occurrence where you can only connect to the LTE stream but can't connect to 4G/EDGE, try sending a text, it will fail. (i've been in this situation once, at my school in this strange building where I could get LTE signal but not 4G signal; but it was only that day)
