Follow these steps to change a simple setting in the GPS system that prevents it from eating away at your battery. It has NO NEGATIVE effect on GPS performance. In fact, my GPS works extremely well despite the misleading 30m bug.
Turn on your GPS (from the Status Curtain or Power Control widget).
Open Dialer on your phone and type in *#1472365#.
Tap on "Setup".
Tap on "Position Mode".
Tap on "Starting Mode".
Select "Cold Start".
Another way to prevent unnecessary power usage (Until Samsung fixes this which I suggest people complain to them about) is to disable your EV-DO data connection.
I do it manually though these steps:
Open Dialer and type in *#4636*1111#
Tap on "Phone information"
Press the Menu button
Tap on "More"
Tap on "Disable data connection"
To restore the data, just follow the same steps but the menu will show "Enable data connection"
Other methods are to use the free version of JuiceDefender (Cancel the useless installation of AOSP helper).
Disconnecting data still allows phone calls and text messages to go through. This is perfect for people who have good 4G and WiFi coverage so you'll never be without data and still get good battery life.
Please keep this thread clean of any questions, if you need help just PM me. Only report any feedback or suggestions in here.

Solutions not working. Did you test for long enough? 24 hours at least with no reset? Restarts clear cache as does any manipulation *#1472...
My tests show ANY manipulation of *#1472... flushes expired but stuck xtra data so teh poofs are not really valid since you get an instant lock if you change it to cold start and back to hot.
make sure to check after one day with no resets (which flush xtra cache and give you an immediate fix anyway.) I have been testing warm start for 48 hours and thought I was ok, but in fact once emphermis expired, typcial situation of 8 to 11 seen, none in use.
Also staying in same place will render ephemeris checking less valid.
I have three Epics devices. I have been experimenting with old, one warm and one hot, reset, take a fix tonight, turn off gps call applications, and see which are holding expired ephemris and not fixing those seen 10 hours later from a different location.
What I know for sure is of the four Epic location problems*, the main one, seeing sats and not using them, is a clear symptoms of expired xtra data (epehmeris. almanac, and sometimes net time.)
I have been reading for the last few days this:
http://android.git.kernel.org/?p=pl...s.git;a=blob;f=loc_api/libloc_api/loc_eng.cpp
It seems gpstest (author:Lookwood) does have a function to clear xtra but it is not workign on Epic. I beleive the call in android would be
" loc_eng_delete_aiding_data (GpsAidingData f)"
Other notes:
1)It seems omniaII had a similar problem.
2) forcing cold start is not an optimum solution anyway as absent network xtra data source (a sprint connection), aka standalone gps maybe will be forced to pull almanac at each and every LBA gps call, meaning unnecessarily long times before acquisition (TTFF) in true standalone
*Epic location problems I am seeeing
1) GPS. Failure to flush invalid and expired xtra (*ephemeris and almanac)
2) GPS. mediocre to poor SNR ranges
3) GPS: invalid accuracy (false number hardcoded not dynamically calculated)
4) cell based: occasional abject failure to produce location from network alone.
A proper tuning it seems to me is setting the TIMING of the xtra data flush coordinated with QOS timing of a renewed xtra data attempt if Epic sees sats but you cant get a fix in say 2 minutes.

Hello
Im in a dilemma right now. I absolutely love my touch hd so far but am at a crossroads. I need reliable push mail from my gmail account to my mobile... but so far reliability doesnt seem possible. Would appreciate any sort of guidance.
Im trying to have my gmail send all my mail to my thd device as quickly as possible. I cant afford to wait for it to arrive with a lag of say 10 minutes. It has to be as instantaneous as possible.
The problem with THD i find is that when the display is turned off, the data connection is also turned off. So the next sync only occurs when i turn on the display. When display is turned off... no emails. Ive tried tweakHD in an attempt to keep data connections always turned on, but no luck. Im not sure i set it right though.
Can reliable push mail be achieved on my thd? Should i move over to a blackberry device? (considering blackberry storm) Any help would be appreciated.
thanks
ian
Iangohye, the answer is yes...I had this issue for a long time before solved. The long and short of it is, at least for me, it was a power management problem. I needed my exchange mail, but as soon as I put the phone in standby, it would disconnect the data connection, and would not reconnect until I turned the screen back on. What would happen is, while in standby, my data connection would connect and then something would cause it to immediately disconnect. Some power saving feature. Try this first:
1) Go to programs->phone->menu->options. At the bottom of the screen you will see tabs. Tick the "data" tab and see if the box "disable data connections when device enters sleep mode" is checked. This was unchecked for me so clearly not the issue. Some people, for whatever reason, do not have this option. If you do, and it is not checked then see the next step below, if it is checked, uncheck it and see if that solves it for you.
2) To check whether there is a power saving feature within your power management causing the disconnect in standby go to settings->personal->sounds and notifications. Set a sound for data connection established and data connection disconnect. Set your mail to sync in an interval such as 5 minutes. Put your phone in stadnby (screen off). Once the screen is off, you should hear the data disconnect sound. After five minutes you should hear the data connection established sound and then immediately hear the data disconnect sound. If this is the case.....
3) Install Schaps Advaced Config. Tap his "Power Management" option. In the drop down options, disable all of the power management options and set "AC resuming from suspend" and battery resuming from suspend to 60. Soft reset. Establish a data connections, and put the phone in standby. If your data connection stays on, go through each of the power management options in adavanced config and enable or disable each until you find which one is responsible for leaving your data connection active. The reality is, there are only a couple of options there that cause it, but for the sake of confusion, I would go through them all. Also, for your purposes, I'm not sure whether setting AC and Battery resuming from suspend to 60 is necessary, but I do it anyway.
This is what solved it for me and I hope the same for you.
Hi Sean3
thanks for the help, ive done everything you told me to and it seems like its working as i hoped it would so far.

Blackberry works great.
I installed 3G WatchDog and its in constant use. I installed SpareParts to look at network usage and the first item is 0 and when I tap on it, it FCs. I am going to wipe and reflash the ROM later and take a look later but anyone have this problem or a solution? Or a way to see what app is using my connection constantly?
Not sure if this helps, but in Settings - Wireless & networks - Mobile networks - there is an option for 'Enable always-on mobile data' which I believe keeps your 3g running all the time.
http://androidforums.com/147137-post14.html
That is probably one of the better explanations for what disabling 3G Always on does. Seems like it's a huge battery saver.
OP: have you tested the suggestion in the article donatom3 linked?
Let us know...
My Wifes EVO is having the same issue. Her phone is contantly downloading data. I got a clue when I looked at her data useage and she clock 14GB for the partial month.
I shut down services until I found the culprit. It was "People". I checked sync setting and all and it seems they are all set to 1 hour or more intervals. When I force a close of "People", the data access stops and goes to normal even if I restart "People".
If I shut down the phone and then turn back on, then it seems to start all over again.
As a bandaid, I have set Advance Task Killer to kill the "People" service automatically every 30 min.
I would sure love for someone to find a more permanent resolution.
Can't you just remove it from the home screen, and it will stop using the data?
I have an Optimus V, but have seen many, many posts dealing with this issue in a number of different threads, but haven't seen an automated fix for the data drop/time without signal/battery usage issues many people have been experiencing that seem to be related. I'm aware of the fix50 app that seems to take care of the TWS issue for me but does nothing for the data problems or rapid battery draining. I have had good luck with the following procedure posted by abcdfv in the "[How-To] Better battery life, reduce time without signal" thread:
NOTE: when you first open the testing menu, it will show it as CDMA auto (prl). This is a visual glitch, in reality, it is set to GSM auto (prl). If your TWS is around 50%, it means it's GSM auto (prl)
First things first, go into Settings> About Phone> Battery> Battery Use> Cell Standby. Assuming your phone has been on, or off the charger for ~10 minutes, it should show Time Without Signal at around 50%.
Next thing, press HOME, and bring up the dialer. Dial *#*#4636#*#* (Do not press "Call"). After a second, it should bring up the "Testing" menu.
Go into Phone Information, press MENU, and tap "select radio band." You should experience a Force Close, don't panic, this was supposed to happen. Scrolling down shows that the preferred network type is GSM auto (prl).
What this means is that even though you are connected to a CDMA network, your phone is trying to find a GSM network, preventing the radio from sleeping, and causing excessive battery drain.
Remedy this by tapping GSM auto (prl), and changing it to CDMA auto (prl).
Now your done, your TWS should drop dramatically, and you should experience much better battery life!
Note: You need to do this every time you reboot.

My question is this- has anybody developed a script or app to automatically do this process? If not, would anybody know how to tackle such a thing? I did find a post over on another forum with a script to periodically check for network connectivity and toggle data off and back on if a connection wasn't present, but I'm really more interested in something that would just run at startup, like the fix50 app, but would do the process listed above instead of a simple Airplane Mode toggle. I did install Any Cut and at least now have a shortcut to the testing menu, but it would be great to have something automated.
Thanks in advance!
Man- I think this is the most popular post on the xda forum!

I've read a lot about people having issues in KitKat 4.4.2 and I'm having the same. Which is the GPS not locking a location. I've tried many things like apps such as GPS Fix and even flushable zips. I don't know what caused the problem but I have gone back to stock and still nothing. As of right now I'm running PA Beta 3 along with the latest Franco Kernel #206. Please I'm hoping someone has a fix

If you haven't already, try the "GPS Status" app.
There you can hit the menu button, press "Manage A-GPS State" and reset the AGPS cache. Then go to "Manage A-GPS State" again and download new AGPS data in place of the cache you deleted. Make sure you have a working data/wifi connection when you do this.
Note the number of sats fixed (they show up as visual green bars, you can also find the number on the left side of the "/"). You generally need more than 5 in order to get a steady lock, though that admittedly is tough if you have any overhead obstacles. This app will also tell you the "time to fix" so you'll know if it takes too long.
If you want, you can set it up to have a constant notification whenever the GPS is in use, and that way you could pull down the notifications bar while you're on the Maps app, then hit the "GPS Status" notification to pull out the app and get you a faster lock. At that point you just press the back button to return to Maps, whence it has fixed a location for you, and voila! You can even calibrate the compass.
Also, another thing you could do is set it to automatically download new AGPS data for every given length of time. I personally set it to every 6 hrs; that way if the GPS starts acting up, you'll automatically get new AGPS data within the day to help it lock faster.
Hope this helps!

I got an update yesterday which was pretty small in size, around ~40 - 50 MB. The Android version was not updated to 7.1.2 so I presumed it was the monthly security patch and not the OTA beta. I'm on Project Fi and experienced my phone dying with 20 - 30% battery remaining with the Nougat update a couple of months ago. But today my phone died with more than 50% of battery remaining in the middle of the day. Is anyone else experiencing the same problem after the recent update?
So I just finished chatting with Google support person and asked them to raise a bug for this but they insist that I keep my phone in safe mode for at least a day and do a factory data reset before escalating this issue.
Here's the email that I got:
Hi sleekstrike,
Thank you for contacting Google Support Team.
As per our chat conversation, I'm sending you this followup email. Most phone and tablet batteries will drain quickly as the device is used more often or more intensively. If you feel your battery is draining too quickly, we need to determine if this is due to normal usage or due to a faulty battery. Below are some steps and tips that may help determine and resolve the issue.
You can also check out our Tips for making your battery last YouTube video.
Step 1: Restart your device.
Restarting your phone will clear temporary files and may resolve any app-related issues.
Hold the Power button until a menu appears prompting you to power down the device. When the device powers off completely, press and hold the Power button until your device powers on again. Step 2: Check for system updates for your device.
Downloading and installing system updates for your device can help prevent and resolve issues with your device.
Go to "Settings" > scroll down to "System" > touch About phone (or tablet) > touch System updates. If a system update is available, download it. Step 3: Check for apps updates on the Play Store.
Downloading and installing available app updates will ensure that the app is working as intended, which includes fixes for bugs and issues on previous versions.
Open the Google Play Store app. Touch the Play Store icon > touch My Apps to view your downloaded apps. Apps with available updates are labeled "Update." It's recommended that you select Update All, but you can individually choose which apps you want to update. Step 4: Settings adjustments and other actions.
a) Use the Recent Apps button to close unused apps that may still be running.
The Recent Apps button is the third touch button at the bottom of your device that looks like two rectangles on top of each other. When you touch the Recent Apps button, you can swipe left or right on an app to dismiss it. Some Android users are not aware that apps on the Recent Apps list are running in the background and may be contributing to memory and battery consumption. b) Temporarily turn off features not in use.
Location services and GPS: Settings > Location access > Turn off access to your location. Bluetooth: Settings > Wireless & networks > Slide the Bluetooth switch to Off. c) Use Airplane mode in low/no coverage areas if you cannot use or don't plan to use data over your mobile network.
Settings > Wireless & networks > More… > select Airplane mode. Although mobile network connection is disabled in airplane mode, Wi-Fi can be re-enabled: Settings > Wireless & networks > Slide the Wi-Fi switch to On. d) Enable auto brightness.
Settings > Display > Brightness > select Auto e) Reduce the delay before the screen goes to sleep. The screen is often the biggest drain on the battery, and this step will reduce drain when the screen is not in use.
Settings > Display > Sleep > Set small time frame (such as 1 min or less) f) Minimize use of graphic or memory intensive apps when you need to conserve battery. This could include video streaming, gaming, or camera use.
g) If you know you are going to use intensive features more than usual, such as when traveling, plan in advance.
Plug in your charge cable while using GPS navigation in your car, if able. Carry around your USB cable and plug into USB ports to charge, if able. Bring a backup battery for your device when taking many photos and videos, if possible. h) Disable application notifications from apps that are giving you unwanted or too many notifications.
Settings > Apps > touch the specific app > uncheck Show notifications Touch the Back button (curved arrow toward the bottom left of the screen) and repeat as necessary for other apps. i) If you're using a tablet and have multiple user profiles, switch to unused profiles and (similar to step a) use the Recent Apps button to close all the apps open on that profile.
Alternatively, you can delete unused tablet user profiles: Settings > Users > touch the trash can to the right of the profile you wish to delete. The main user profile can't be deleted. If your battery still drains unusually fast after going through all the above basic steps, try Steps 5-7 below.
Step 5: Use the Battery settings.
Visit our Manage battery life help article. Check battery level & usage details of your device to determine if any unused features or third-party installed apps are draining the battery quickly. Step 6: Enable safe mode on your device.
In safe mode, all third-party applications will be disabled. This can help pinpoint issues caused by third-party installed apps. To restart your device in safe mode:
Ensure your device's screen is on, then press & hold the Power button. Touch & hold the Power off option in the dialog box. Touch OK in the following dialog to start safe mode. To exit safe mode, turn your device off and on again. It's recommended that you try safe mode for a few hours or up to a full day, if able. If your battery continues to drain abnormally quickly while in safe mode, try Step 7 below.
Step 7: Reset your device to factory settings.
If your device continues to drain quickly, resetting the device to factory settings may resolve the issue. Resetting your device to factory settings will erase all local data on your device. Backup of your personal local data (pictures, music and video files) is recommended.
To backup personal data on your device To reset your device to factory settings After resetting your device to factory settings, continue to use your device normally to determine if your battery issue is resolved.
If your battery issue was resolved during these steps, great! You can help other customers with similar battery issues if you reply to this email to let us know which step best resolved your battery issue.
If your issue was not resolved and your battery still drains abnormally fast, call us or reply to this email and reference that you already went through all of our Battery Drain troubleshooting steps.
If you have any more questions, please reply to this email. I'm happy to help!
Thanks! Kiara S The Google Support Team
This is their initial steps they want you to try before they do anything. If you bought the phone through the google store they will replace it even if it's out of warranty. At least they did for me. All I had to do was call them back and tell them I followed these steps and the issue was still happening.

It's not the update- It's your battery getting worse. Keep working with Google until they send you a replacement, back up all your data, and transfer it to your replacement phone when it arrives. In order to simplify restoring to the new phone disable password/pin/fingerprint first before making a backup on your current phone. Good luck.
