Well like everyone I had the GPS issue and it was frustrating. I do run an app killer and I always notice many apps (especially the preloaded ones) Keep launching themselves. It got rather irritating. Specifically Telenav.
I noticed with Telenav my GPS would be very flaky. Once I got "killed" it the gps seemed to improve. I thought to myself maybe I'm just being paranoid.
Did a bit of research and found an app called "Start UP Auditor" which completely kills an app and restricts it from every starting up again. My gps seems to be working much better now.
I drove a few miles and on the Verrazano Bridge here in NY and the GPS was super percise. When I was at the end of the block it was at the end of the block as well at the same time. Not like it was before.
Now I can launch google maps and it will find me exactly in front of my house and not 200 feet away.
Takes a solid minute to lock on. Not more but not less unfortunately. So there still is a bit of a problem but for me at least it has exponentially gotten better. Versus it not even locking on previously.
I think I might be on to something. I cannot give all credit to me because I saw on a Tmobile forum someone say that they think the problem might be with the self launching apps so that's where I started to draw conclusions.
EDIT: Scratch that one min thing. It seriously just now took me 10 seconds to lock on and the GPS to start talking to tell me where to turn inside my house. Issue fixed?
I completly removed TeleNav and I still have GPS issues... It is not any software causing this problem. It is a Hardware / Firmware / Driver issue.

Same here, one of the first things I did after rooting was remove all the bloatware, and Telenav was one of them.

Hmmm... Interesting.
My GPS issues seem to have disappeared after killing Telenav.
This just takes me back to the drawing board once more. I just do not understand...
I would like to see others responses. Does there happen to be vibrants with different firmwares?
So what happened to me?
Was it some magical stroke of luck?
Wow.
Initially, disabling TeleNav gave me a significant improvement in GPS performance. Indoors, I went from having 50-60ft. of accuracy (with multiple locks), to 12-15ft. of accuracy with a single lock. Initial accuracy was in the upper 40s, but quickly dropped to the highest accuracy I've seen with the device (the 12-15ft. figure) - indoor or outdoor - within a minute. Crazy.
Outdoor, on a perfectly clear sky, the best I've achieved was previously 25ft. of accuracy.
I rebooted (the phone froze, wheee!), with TeleNav still selected as disabled, and now, I'm only getting 30-52ft. of accuracy with a single lock. This took about two minutes to come down from 170ft. or so.
GPS settings have been switched to 'Automatic', from the stock supl server, for all of these tests.
Maps still shows me in Issaquah, initially (incorrect data), but quickly updates my position my exact location (within a few seconds). Previously, Maps would take at least a half hour to place me in even the correct city! Margin of Error: ~50ft. or so (shows me on the street, rather than on my property), within seconds.
Compass, as expected: still totally ****ing broken and ****ty.
I can confirm that - besides not being able to lock onto more than a single sat - I'm seeing drastic improvements. Thanks for pointing this out.
Still, I'm not sure the improvement will be enough to convince me to hang onto the device while we wait to hear from Samsung. :/

Yea like I said in the OP the fix is better but there definitely is a problem that needs to be addressed. That might be either hardware or firmware, All thats left is to wait for sammy to fix it up. However my GPS performance for my needs is more than exceptional.
I have noticed that while running GPStest, Google Maps starts to work. Something is wrong with the API.
If anyone is getting black screen freeze ups, disabling GPS will clear that right up.
And, we're back to square one. So much for that.
Location services can no longer locate me, and show that I'm in a neighboring city. Nothing I adjust fixes this for more than a short period of time.
Oh, Samsung...

I wonder if they can't even find the issue yet. It will probably be fix in the 2.2 update.
I removed TelNav within 4days of owning my phone and it really for me hasn't changed a thing.
What helped me was turning off the wireless location feature. From what I noticed it looks for your location based off the cell towers first then it looks for your location via GPS. If its slow to find you via wireless then well its slow to find you via GPS too.
I didn't really tried the GPS when I saw the threads saying there was a problem with it and I read somewhere about "how to fix it" so I applied the fix before even using the GPS before, so I have no clue if I had problems or not, but after the fix, the GPS locks in about 10 to 15 seconds and gest my location on the spot, even indoors.
just change the GPS settings to google servers
Directly after rebooting my gps/navigation seems to work much better.
To make it more clear... I'll be using my phone throughout the day and then i'll try to use navigation. Usually it will just keep trying to find the route but it never actually finds it. I'll reboot the phone and it'll find my location and the route in <10 seconds.

I believe the wifi and GPS share the same antenna. Anyone know which antennas do what for sure?
Our cellular antenna is at the bottom under the bump. The one at the top next to the antenna port does the rest.

Thanks for this tip, I hadn't caught this in the other GPS threads.
I ran and used My Tracks but forgot to turn on GPS. When I tried nav it could not get a fix until I restarted. Next time I'll try killing conflicting apps.

I just deleted the Tel-Nav app and now my GPS locks on in about 10 seconds and is dead on accurate. I even drove 165 miles today and never dropped a GPS signal. I could never do that before.
Does anyone know why the times are off one the gps sensors? My local time is 10:51, but gps test has it as 18:51 that is about 8 hours off.

I've been investigating how to get rid of that pesky background idle battery drain on 2.2. The biggest improvement I've found is from disabling Google location services. With this disabled, my background drain is about 1% per hour. Enabled I see 4-8% per hour. This drain mainly seems to kick in when not connected to wifi AP.
This observation holds true for stock ED01 and sc 2.9.2. GPS still seems to work reasonably well with Google location services disabled, bit it may impact you.
Let me know if anyone else sees the same. Thanks!

Lots of people have commented on worse battery life with froyo. If you're one of those, and its idle drain, then try this out.
If not, mind your own buisness. It definately makes a difference for me. Tested / confirmed multiple times!
Google Location Services does not do anything on its own, until an applications calls for it.
Disabling Google Location Services is like draining your gas tank because it has a hole in it.
Sure, it won't leak anymore, but not only can you not use it, you also will have the problem the next time you fill up.
Fix the problem, don't hide it, imo. You have an app thats draining you if turning off Google LBS fixes your issue.

A constructive comment! Thank you. Before disabling Google location services on stock ED01, I killed every background service that would stay killed, and turned off all widgets and updates. I still had the high idle drain. If what you say is true, it appears there is something systemic in stock 2.2 ROMS abusing Google location services.
Watching cpu usage over time with system pannel and battery state didn't show any suspicious usage.
When using sc 2.9.2, I'm fairly certain the idle drain / location services is only an issue when Google latitude is enabled.
This certainly can't be indicative of ed01 roms or everyone would be screaming to high hell about it...I leave Google location services on all the time and am completely fine battery wise
Sounds like you have a app installed that is using the Google Location service installed, sounds like you need to a factory reset and run a day or so with no apps installed, right now I am running on stock self debloated ED01, and I always have GPS and Google location services turned on, and I have gotten the best battery life I have ever seen on this phone. Not sure if you use Google Latitude, but I have seen that cause some drain on phones.
Its one of the big double edged swords of Android, the ability to have true multitasking can really hinder your battery and this is proof, especially when it comes to a service like Google location services.
Just a thought, maybe if you quit checking your battery usage so much, it might get better.

Come on now, dudes having a problem and trying to help. Just because he is wrong doesn't mean the thread has to go this direction. Instead perhaps it can be used top help him find the true cause, aswell as any one else with similar findings.
Oh and only quoted you cause I thought it was pretty damn funny.
After more testing, I have some interresting findings.
The idle drain I described earlier along with dependence on Google location services holds true while I'm at work. This is a location where I get 0-1 bars of cell signal, and android reports about 60% time without signal. When I'm at home and in good signal area, I can leave Google location services on all the time without high idle drain. Now I know why most people weren't agreeing with my observation.
Now then, to the root of my problem when I'm at work. I know everyone says Google location services is mostly passive and only consumes power when an app is polling for location. However, I'm starting to wonder if this is true for the cell tower portion of location services. Could android be doing some extra background tracking of towers when location services enabled? Or could the phone radio be put in a more aggressive "find a freeking tower at all costs" mode? My experiments at low signal level would seem to suggest so.
Anyone with info or similar test results please let me know. Thanks!

Do you have a WiFi connection when at work (and it setup!), or are you using 3G only? If so, that could be your cause. Google Location Services periodically does send data to Google (read the agreement!), so if it's trying to send off data when you've got pretty much no connection, it could very well explain why it'd be causing such a huge drain on your battery (causing the radio to power up to full power, and continually fail to send your location data off, forcing retries).

Yea, I suppose that's possible. I don't have a wifi connection at work currently. At home I do have wifi, but my wifi sleep policy is set for screen off. To test I did disable wifi alltogether at both home and work, and it doesn't change my idle drain issue. The theory that Google location services is desperately trying to send data over a partially working cell connection does make some sense.
What I've found so far with ed01 froyo has been vastly improved in most regards including battery. My idle drain is almost nonexistant with the comm.rom 1.2 & nemesis' 1.3 kernel with uv/oc to 1.3ghz. It only eats battery when I'm actively using it & there it is more aggressive than eclair depending on what I'm doing. I have google services & standalone gps always on & never use wifi only 3g and easily get 16+ hrs on a charge.

After upgrading to Evilfascinate 3.x, I found if I left my WiFi on and my 3g my battery would barely make it through the day... Now I only turn them on when needed and I am running a couple of days before I put it back on the Charger...
I have done the same with GPS, only turn it on when I need to know where I am or where I am heading...
Hai,
Since nobody bothered to answer my call to track down what drains the battery I decided to just post my findings and you do with it whatever you like...
In recent couple of months I've been experiencing quite nice battery life, almost a week on standby, which is basically on par with original LG ROM. The trick is simple:
It's happening as long as the Gallery app is NOT running.
I don't know what this piece of software does but when it's loaded to memory it stays in there and ignores attempts to terminate it, doesn't sleep when phone wants to and eats battery in a matter of single day. Unfortunately it seems some other apps use it directly or indirectly, like when Wi-Fi starts and/or by Market for example. Thus my solution is just to force close the Gallery after I finish activities which seem to require it.
I don't know whether root of the problem is with the app itself (like, CM modifications made so it's more cool, at the price) or it's just something else unearthed by certain SwiftDroid's configuration. To anyone who wishes to furher investigate my sincerest good luck. And I'd be grateful if results were published too.

You do with your phone what it damned pleases you. In case you haven't noticed the battery life is most often reported as either standby time or call time. In my typical usage battery lasts no less than two or three days but what 'typical usage' means may mean totally different things to me and to you.

Hm, even more shotgun approach to what I described. Having user data could be the primary reason for keeping the app installed. But thanks for tip anyway, may come handy one day.
There is gr8 app on xda, better batery state. With this app you can see what aplication keep wake lock, use cpu, gps, etc...
So, I'm rooted on VZW with no OTA and suddenly had abnormal battery drain today. Any idea why this may be happening?
Mine is kinda high today as well. I saw something about Google having issues today with email and other applications. This could be related, or phones can't connect to Google so it just keeps on trying.
Sounds nice but don't know if it's true or not.

Install Greenify. Hibernate all the APPs that you don't want notification from first. This app doesn't allow APPs to Wakelock you're phone. Once you find which offending account is the issue you'll be ok. I found that Facebook woke up my phone thousands of times and I have up notifications. Best choice ever ?
This app requires root and free in the app store.

Greenify can't touch system apps to my knowledge but yes, it is an excellent solution for rogue apps that take up resources when they shouldn't. :good:
As far as the google services battery drain, I eliminated that by simply turning off google location services. The actual GPS is so quick to lock that I haven't run into a scenario yet where I'd absolutely need to turn it back on.
My location services are off. Doesnt seem to help me much. I also bought donation greenify and greenfied Google Play services and Google Play Store

With 15:34 for time on, and 1:45 of screen on time, I'm currently at exactly 50% battery. I feel it was something awry with Google Services yesterday and an isolated issue. Location services were off today, but I did nothing with Greenify, yet at least.

How is that working? Considering doing the same as I've already tried removing the sytem app and replacing with Play Services from the play store. That seemed to work for a few days but the nip wake locks are worse than ever right now. Killing the otherwise stellar battery.

works great today..... google services error has gone away today and my battery life seems longer. :good:
I just froze google play services and will look at the battery stats later to report the difference. What apps are affected by freezing this though? It seems Hangouts is one.
I don't know why, but all my days are pretty much exactly the same location-wise and some days have huge wakelocks, others don't.
Aside from installing the play store services which seemed to help quite a bit, I've also noticed a nice drop in wakelocks since I went on to Google's Location History dashboard (https://maps.google.com/locationhistory/b/0/dashboard?hl=en) and deleted all my history so maybe it could re-create it.
One thing I've noticed is that on high-wakelock days, my GPS is going nutso. My point markers on that dashboard will have me moving ALL OVER the place, even while I'm just sitting at my desk at work.
This leads me to the conclusion that signal plays a huge role, and I do have bad signal at work (1 bar, and can't get a good GPS lock at my desk).
Also, you can minimize these wakelocks without the use of Greenify by simply turning off Location Reporting and Location Using WiFi and Mobile Networks. This dropped my wakelocks to pretty much 0, immediately. But you'll lose things like weather widget geolocation and some Google Now features. On the other hand, this is a more viable option than freezing services which can cause you to lose push notifications for GMail among other things.
I've been messing with this throughout the day today and the problem is high NIP wakelocks originating from Google Services...specifically the Network Location process. So the fix for me appears to be disabling newtork location while leaving GPS location enabled. This is usally the reverse of how I do things but for this phone, it may be the better solution. Google Now is still working for me, as is maps/navigation. There may be some casualties of disabling newtwork location but I haven't run across them yet. I've always viewed these two options as coarse (network) vs.fine (gps) location. So I'm hoping GPS picks up the slack and I don't lose any functionality. What I could see happening is that it just takes longer for location to be confirmed because network location is faster. I'll take that in lieu of battery drain however.
Still need to run like this for a couple days to see how things go but I was getting hundreds and even thousands of NIP wakelocks in a run cycle prior to disabling network location. I'm now getting zero.

You are correct, there's the first casualty confirmed. I'm going to run like this for a few days and see what gives. I don't use the cards anyway so no issue there. If anyone knows of other functionality loss, please speak up.
Like some of you have said, I don't rely on Google Now cards, and I don't leave the city I'm in, so for things like weather, I am find with the hourly syncing of my weather app. If I do need GPS/location services, it's not hard to toggle and battery life is incredible. I feel it was just something going rogue the other day. Today, with locaiton off, I've been off the charger for 15:34 with 1:24 screen on time and I'm at 58%. I spent a good portion of today in a sub-basement on airplane mode, with wifi active in the background though. Walking around campus, I used Songza via 4G due to some wifi weak spots. I can't be happier with this phone, as my GNex would have long since been dead, even on airplane mode.
EDIT: Holy ****, 15:34 sounded familiar, checked my post from yesterday, I responded then at the same time off the charger...
Okay so I may have fixed it on my phone.
I forced closed "Google Play Services" and "Google Devices Framework" then rebooted.
Google services was using it 50% of battery consistently through the day and now its down to using 2% of battery. I'll come back at the end of the day with battery stats.

this night was a pain.... the phone was on 83 and when i wake it was on 76..... google services was draining all my battery, who could fix this?
I've played Ingress for several months. One thing I do daily is recharging 20~30 portals during my commute by bus -- open Ingress after getting on a bus, waiting for the GPS to get fix, and collect XMs and recharge.
However, in the recent one or two months, my phone's not able to get me GPS fix near my home -- even on a square. GPS status shows many sats in yellow, but none becomes green. Rebooting the phone doesn't solve it.
When I get to another place, two or three kms from my home, my phone still can't get fix. What's strange is, if I reboot my phone there, and try GPS again, it usually gets instant fix.
Also, I can always get instant fix anywhere near my working place.
I have two questions:
1. Which of the software parts affects GPS performance? I switched among multiple ROMs during these months, but I should be always on cloudyfa's KK baseband.
2. Anyone else has encountered the situation that you stand on a square on a not-so-cloudy day, with no high building around, 24 sats in sight, but your phone just can't connect to any? Has anyone solved it? How?
Try using faster fix app and change the ntp to your location and see if that helps

Download GPS Test from the Play Store, go to the app settings and press Update A-GPS while your data connection is on. Wait a few moments and the app should lock on to GPS satellites. You should be good to go from there.

GPS Status from play store also has that A-GPS downloading feature, and that's not helping me either.
If not changed nothing in software that can cause bad reception (build prop edit, rom, ...) try something hardware

Thank you! Good video. I will try it after having tried all software ways.
Which properties in build.prop affects GPS performance? I'd like to check them first.
Also, try TopNTP app before opening up the phone.
I've been through a few smartphones and running various ROMs on each, here's my observation.
a. If the phone's gps takes long time but eventually locked then those apps mentioned above do help.
b. If the phone's gps take long time and never locked then those apps above are useless, they won't do a thing.
My advice 1: restart the phone and see the gps gets locked reasonable fast, if not
My advice 2: changing ROM. Do focus on firmware first before touching hardware.
Long time means 15' or more.
