pls recommend me any gps app that wont suck ur battery juice so fast...

A GPS app that won't suck the battery? Good luck in finding it

Guess non available

Get a car charger. Even a sole gps device also need car charger when in use

I tried Waze for the first time today and it was... Fun!

Basically, the problem is not on the app. But GPS chipset really requires a lot of power to lock to the GPS satellites. That means whatever app you use, it will be the same story

It works to some extent. But iP4 and 4S get warm pretty fast. If the heat is no longer tolerable, it will stop charging, this is true for most smartphone, not only iphone

Until you realize it's sucking data

Nope. Garmin is the best turn-by-turn voice navigation. Voice navigation that is the most accurate by far.
Only recently Papago with the version M8.2.0 improves tremendously, almost on par with Garmin but still not there yet.
Papago relies too much on its screen info which is WRONG.
Very basic principal of safe driving means keeping your eyes on the road and not on the tiny gps screen.
The Papago developers need to put themselves in the shoes of the FIA World Rally Championship navigators.

Waze is nice !!

duh! very informative!
Durian also nice!

There are setting you can do to minimize battery usage. For example, some will automatically switch off the screen when there are no new turning to be made and will automatically turn on the screen when there are. For example, once you turn into a highway and a long drive ahead with no more turning, it will automatically turn the screen off. Screen is one of the biggest user of battery, beside the GPS chip

In general, navigation devices are not designed to work without power supply source. With the display getting bigger and bigger, even the PND are having shorter battery life.

I have never use it purely on GPS and see how long the battery last on my Nokia. But I would guess with the proper setting and on 2G, it will probably last 6 hours to 8 hours thereabout continuous.

on my Nokia?
You had me lost for a while there!
Lemon vs apple!

which gps software is most easy to use..and best for kuala lumpur

I want to weigh in here. I use sygic n Papago and I find Papago is super slow. The screen is quite ugly.
Sygic is smooth an it actually supports retina display. If u want fast smooth performance go for sygic period

Don't obsess over the best app instead focus on what u want. Speed, map, voice guidance lady lol oh btw the voice for sygic pleasant and nice

I also use sygic,

But only for emergency coz battery drain alot using gps on ur iphone

I used Sygic w/o data usage

Waze. The rest of the GPS have to pay lol

Which version of Papago are you using?

Using GPS on iPhone has Sat searching probs esp with tinting on front w/screen...
Any recommendations re true GPS modules/units in such a situation?
