battery life with gps on bike

Hello everybody
How many hours (aproximately) it takes to drain battery when using gps on xda with integrated gps (like artemis, mio a701 etc.)?
It's possible to take a 8-10 hours trip with bike and turned on gps on the xda? Would it last that long?

No way.
Depending on how you set up your device, and depending on a specific phone you may get 4, 5 hours tops.
That's provided you do not use BT / WIFI at the same time, don't talk on the phone and keep the backlight down.
Also if you really want to maximize the battery life you would have to turn the phone off all together (flight mode).
However, you do have the option of carrying extra battery with you. I remember seeing a device (sorry cant remember name or company) that has a 3000+ mAh battery and USB HOST connection. You charge it at home and use it on the road to power / charge any device that takes power through USB cable.

Thanks for replay.
So using pda and gps mouse is better solution, right?
And how long lasts pda with bluetooth turned on? More than 10 hours?
Is it any difference in battery life when using pda with bluetooth 1.2 and one with 2.0? I read on wikipedia that 2.0 consume less energy. Is that true?

Hi,
With my JAMin and a bluetooth GPS I reckon I could maybe push up to nine hours of use, with backlight set to go off after a minute.
I would guess using the inbuilt GPS of the Artemis will reduce this quite a bit.
Regards

I recently went on an 8 day cycle ride with my jamin using tomtom to go from St Malo to Le Cap d'Agde. I have a shimano dyno hub in the front wheel. I set up switch box so that at night it would power the light but during the day would charge my phone.
My GPS lasts about 11hours so only needed charging every otherday. The phone ran on batteries while the gps was charging. Seemed to work quite well except over 30kph when the my regulator seemed to shut down as the voltage was too high for it.
As I had a constant power supply I was also able to play music from the phone to keep me entertained!

I would think this is probably the one levenum mentioned.
Do a search looking for "I-UP3600" this is a small external pack that will power an Artemis for about 6 hours if fully charged, before the Artemis stats to use its own power, very handy gadget. I did read somewhere that they were bring out a larger capacity pack around 5,6A/Hr (the numbers denote the capacity 3,6A/Hr is the one I use), look http://www.busytrade.com/tradeleads/tradeleadsInfo.php?messageID=179864

Here is what I was talking about.

Extended tethering harmful to phone?

Just a quick question if anyone happens to know about this. Is using the WiFi tethering app for an extended amount of time going to be harmful to the phone/battery? I ask because ive been having net issues as of late, and ive been using the phone as my primary internet line. Been doing some online gaming and whatnot, and i noticed that the phone gets very hot.
Used around gig or so of data in the past few days to give an idea. Will this be harmful to my phone?

Hot temeperature is the BIGGEST enemiy of Li-on batteries so yes, runnning the phone HOT for extended periods of times will eventually damage your battery. And of course, hot temeprature is not friendly either to all of the phone components.

The phone knows the temp of the battery, I have had mine shut off several times when it reaches a critical level and won't come back on till I pull the battery or wait 10 minutes or so.

Kcarpenter is right. Tethering makes the phone's radio and wifi radio go into overdrive, transmitting all that data. They will get hot, and they will heat up your battery. But, when the battery reaches a critical level, the phone shuts down and won't start up until the battery is cold.

So keep it in the freezer while you tether
Just kidding.
Seriously, though, I'd only tether until you get your internet back up unless you are set to upgrade your phone more frequently than the 22month cycle.
(I know a lot of people here use their Heros as primary means of internet access but I also think most of us will be eligible for upgrades very soon, heh.)

You COULD update to the 2.1 ROM that Mobile Network Sharing works in. Then you can just tether over USB - No ridciculous levels of heat that way. Then you loose a lot of features.
I had an odd dream last night that they got multi touch working in the 2.1 ROM....I spend too much time here!

You could have a nandroid of the 2.1 for tethering, and then another nandroid to go back to your rom of choice.

Or try PdaNet... it has a USB tether feature, right?

PDA net is good and all, but if you want to let a download run, it looses its conection after a few minutes and you have to reconnect.

The battery protects itself by shutting down under extreme conditions yes, but extended periods of usage while the phone temperature is at 40-50 degrees, WILL kill your battery. It will stop holding a good charge over time.

i had the full version of pdanet and had to get a refund. it wouldn't stay connected for more than 2-3 mins and then had to reconnect. very annoying

pdaNet works fine for me..

pdanet is the best way to tether on your hero, it won't overheat your phone and it is very stable. those of you who are having frequent disconnects should try getting a better signal or setting your wireless as EVDO ONLY and not HYBRID.

Still doesn't work well for me on full EVDO with full bars or on an Air Rave(almost defeats the purpose of tethering), Seems like if I am not constantly browing the web it disconects.

Just keep your phone in a nice ice bath or crygenic chamber.

Maybe you could take the back off the phone and jerryrig a metal heat-sink to the battery.
Best method is going to be over USB though.

There is a wired tether app by the same dev that makes wifi tether. Never tried it though.

I jerry rigged a heatsink for mine. Wired tether app doesn't work on the hero.

it doesnt work with the hero or it doesn't work with 1.5, just curious

Did you try the v1.70-pre2 version of wifi tether? It's supposed to resolve the heat issue that 1.60 had.

A couple of things I noticed.

This is just a couple of things I noticed about the G2X you might find useful.
1. When running multiple apps while charging you can still get a battery drain. When I was driving the other day I had the phone charging while using the GPS and listening to a show on Beyond Pod. When I arrived at my destination an hour later my G2X used over 10% of battery and was very warm to the touch. (This is not the first Android phone I've owned that has done this.)
2. The day I bought my G2X I dove in head first tinkering. I ended up loading the software from the Optimus. Now that I had it on I installed a kernel that would overclock to 1.4GHZ. The processor on the G2X really came alive. The one thing I noticed was my quadrant scores were great! Then I plugged the phone in to charge. While it was charging I ran quadrant again. This time my numbers were even higher. I was pushing scores close to 4000! The nVidia processor in the G2X is a power hungry beast (in a good way).
I hope this helps the smart ones out there who are going to start pumping out the roms for us.

Different car chargers provide different amounts of current. Some only put out 500 mA, which is definitely not enough for a phone that's running GPS and the display and streaming over wireless. I have one that is rated at 1A (1000 mA) and it was almost able to keep up with my Nexus One's power demands (I don't have enough experience yet with the G2x to know how it fares). My general practice when running GPS and streaming Pandora, which I usually do on trips, is to turn off the display when I have more than a few minutes of a straight shot ("stay on Interstate 95 for 59 miles"); the Nexus One was definitely able to charge on my 1A adapter with the screen off, even running GPS and Pandora, and since Google Navigation gave me a heads-up a couple of miles before the next exit or whatever, I had plenty of time to turn the display back on to see the road configuration, etc.
With respect to heating, that's not uncommon either, especially if the phone mount is exposed to sunshine. My mount has hooks for attaching it to a ventilation grill (I normally use it with a suction cup on the windshield), and I think I'm probably going to use that when driving during the day in the summer; the A/C flow should keep it cool enough, I imagine.

On #1. I had GPS on and was also on the phone a lot at the same time. It held its charge + maybe a few percent charge. I was using a self contained GPS map though, so it did not have to constantly update the map.
On #2. - You did what - did your phone still work? Thought those ROM's had different baseband settings, so were not supposed to work on the G2X (unless Paul has tweaked one already).
Can the kernel be flashed on the G2X stock ROM, or only on the O2x ROM?
Am hoping to see a 2.4 ROM down the road. Everyone is focusing on 3.0, but it is not optimized for dual core - only 2.4 and 3.1 are.

You have an OC kernel working successfully on the G2x???

Waa? You flashed an OC kernel for the 2x?

My thoughts exactly ^^^^^^^^^
Please share the link. Does the phone portion function properly? I thought O2x kernels would screw up our cell radios

Out of everything the OP said, the OC kernal was the only thing important it seems lol.
Not charging + on a car charger is normal. Same as with computer USB charging. If your doing something intensive on the phone such as wireless tether / GPS + stream data + using voice minutes then wall charger is needed. This is almost common sense.

+1 for OverClock kernel information.

Little skeptical of the OP claims about overclocking. The baseband should get messed up unless there were some changes made today or late last night.

Why do bluetooth and wifi eat so much battery?

On my Galaxy Nexus and Droid 1 before that, bluetooth and wifi were nowhere near the top of my list of battery drainers. On my Prime and now my Infinity they are the top 2 when used, is the common for all tablets? Seems ridiculous that these functions draw more power than the screen.

I think it's a bug in the software, there is no way that Wifi eats up that much battery.
Sent from my ASUS Transformer Pad TF700T

Chances are its a bug that will have to be ironed out.
Lets use the example of a laptop. If your connected to a wifi and roaming around there is actually a setting you can change that will determine how agressively the wireless adapter searches for a new network. The more aggressive it is the more often it will search for different access points and try to connect to them. More polling = more cycles = more power used.
If the wireless adapter in the tablet searches for a network to connect to, or a stronger open network that it could connect to, say, every 3 seconds it would be a tremendous battery drain. The same thing for Bluetooth, if its searching for saved devices (say for instance, your bluetooth headphones) every three seconds it will drain your battery pretty quick.
Now if the polling rate was changed, say, to every minute, or two minutes, or five minutes, or whatever, then it would dramatically reduce the power used by the radios.
Additionally, the transmitting power used for those radios can play a big factor in battery drain. If you are three feet from the access point and the wireless adapter is transmitting at full power thats going to be a waste of battery. It could, theoretically, determine you are close to the AP and drop the transmit power down to, say, half, and reduce the power used greatly.
Im guessing that the proper balance between performance and power savings has not yet been implimented in the tablets. Either its "All or Nothing" which, in my opinion, is kind of rediculious. Look for updates from Asus and they should have this fixed hopefully sooner than later. Custom roms should also be able to tweak this. There ARE settings in android that can address this, its just a matter of will Asus give us access to them without voiding our warranties.
To further back up this idea, consider this: My SGS2 has the ability to share its 3G connection via wifi. If i use this feature my battery will drain VERY quickly, easially within the hour my battery will be dead. Why? Increased wifi / 3g traffic, more cycles used, more power going to the antennas to transmit and recieve signals at a greater frequency. Using custom firmwares its quite easy to tweak the antennas for performance or power savings.

charging time drastically different with/without wifi enabled

I recently bought two Pixel 3's. Mine charges super fast, but my wife's take 3x-4x as long, even with with same (original Google) charger and cable (showing "charging rapidly"). I recently discovered that when I put her phone in airplane mode, or even just with wifi disabled, it charges as fast as mine.
You would think this signifies that some rogue app is doing lots of networking stuff (like backups or something) only while plugged in (as the unplugged time between charges is roughly equivalent for us) but Simple System Monitor shows no significant network usage during this period. So, what gives? Any other ideas? The only difference between our phones is the set of apps installed.
On a side note, I cannot seem to view CPU usage, apparently by design, making it hard to directly inspect the problem. The device is running Android Pie, like all Pixel 3's, and is up-to-date.
Thanks for any ideas or help!
