Does Navionics kill your battery as fast as mine??

I run Navionics Boating on my iPhone 6s, as a backup/companion to a Garmin 740s (and a Lowrance Mark-4) which are mounted on my boat. I love the Navionics app, but DANG, it will suck my phone DRY in about four hours! I mean 100% charged to 100% DEAD.

No other GPS app does this to my phone. Does anyone else have a similar issue?

Hey,

I just think that's the nature of apps that require the screen and GPS to be on all of the time. It happens on my iphone if I run google maps.

Better have the device plugged in if you want the screen on, or just turn the app off until you really need it.

Yes, that sounds fairly typical. If you can't have your phone plugged-in to a fixed USB port, there are lots of battery packs with USB charging ports available, with quite high capacities. I use them on weekend trips, when the boat USB charging ports are always in high demand.

Put your tablet or smartphone on airplane mode, gps still works but the phone will not be using power to connect to phone service or wifi.

If I allow my screen to go off it does a lot better on my Nexus 9. I have run a 6 hour track like this with minimal battery usage. I know if your truly using it to navigate you would want the screen on all the time, but that seems to be what is really killing the battery.

Re: Does Navionics kill your battery as fast as mine??

Dont know if this would be of help to you but I have found it to be very useful.

Celltronix. 12000mAh Li-polymer battery
Solar charging:5v/200mA

they make them with more capacity, mine's the 12000mAh, it will recharge my phone 5-6 times before needing a recharge, solar or 110v. I just plug the phone in to it and set it the light. you can charge and discharge at the same time. I bought this one at a truck stop for 50 bucks. I tried to post a link and or pictures but this site won't let me. It's about the same size as my phone.

+1 for putting it into airplane mode. Since the maps are stored on your device once you download them, you just need the GPS signal to plot your position and not the cell signal.

Re: Does Navionics kill your battery as fast as mine??

I've seen plenty of apps do that. If the app writer hasn't provided options in the setup, or the user hasn't used them, and the app is running at full screen brightness with high GPS activity (or simply isn't turning off the GPS when not in use) that's all pretty typical.

Complain to the app developer, there's little excuse if it is simply sloppy programming (too resource intensive) these days. Or only run it on a device that is hardwired for power.

Re: Does Navionics kill your battery as fast as mine??

All good ideas. Leave the app running in the background and just put the phone in sleep mode, turn it on to double check your navigation when you feel the need.

I use my phone to stream music while I sail as well as backup app, so I just leave it plugged in. These things are amazing when think of the multitasking that is going on. Playing music, bluetooth, constantly searching for cell towers, wifi, GPS, incoming texts, email alerts, my ebay notifications are on, and then my mother calls to let me know it might rain.

edit: Good thing no one watches porn on their smartphone. The darn thing might implode.

Yeah it eats battery, your options are to turn the screen off when you aren't looking (slightly better) or plug it in while you use it.

It's a little better if you download your charts for the region, then turn off cellular, wifi, and bluetooth. But the screen on all the time will always eat battery.
