I see lots of posts around the Interwebs complaining about battery life on smartphones (specifically Android ones, since I don't hang out on sites that are aligned with evil Apple), so I decided to consolidate my knowledge for people with Slide's to improve their battery life.
DISPLAY
This uses about 80% of the power according to battery use on auto-brightness. On a bright day I can read the screen at about 1/5 position on the brightness bar which cuts down heavily on the battery use.
There's not much else we can do to cut down on screen power usage, so moving on.
CPU
This one requires SetCPU, I strongly urge you to buy it from the Market (it's just a few bucks IIRC) and supports the AWESOME dev. If you're cheap just go download it from that link.
Once you have it you'll want to set up profiles! So click profiles, check the box next to the Sleep profile and choose 480,000/480,000 with ondemand scaler! I have no idea if it actually changes anything but the placebo effect is nice. Next back out of that and set the CPU governor to performance. What this does is clock the CPU to 600mhz constantly instead of scaling between 480mhz and 600mhz as the additional power is needed. It cuts down on choppiness while barely increasing the amount of battery required (in my experience the Slide tends to jump up to 600mhz when I'm not doing anything anyway).
Sync
Turn auto-sync off or set the sync intervals to the highest number possible (once a day I believe). It takes power and most of the time doesn't download anything important. If you really need some data just go and hit Sync Now and, well, it syncs.
Autostarts
There is this nifty little paid application in the market (costs like $1.25 or something) that you absolutely need: Autostarts
Basically applications launch when triggers are triggered, alot of these are pointless and just take up RAM and power.
These are what I have disabled:
After Startup
{Any 3rd party apps that aren't widgets}
Calendar Storage
Download Manager
Voice Dialer (unless you, yaknow, use it)
Maps
Mail
Calendar
HTC Media Uploader
My Account (unless you like the power alerts that take up power!)
Connectivity Changed
Download Manager
My Uploads
HTC Media Uploader
Genius Button
Media Mounted
My Uploads
Application Installed
Voice Dialer (wtf?)
Pico TTS (sem-wtf?)
Application Removed
Voice Dialer
Application Replaced
Maps (lolwut?)
Autokiller
There's an app called Autokiller, it changes the internal task killer's settings as to when to tell an app to shutdown (at stock settings this is almost never).
I use the moderate preset, but you may want to increase it if you never want to have to manually kill a task. Note that this method tells apps to cleanly shut down so data is saved (such as the page you are on in the Browser)
Additional Settings
In Mobile Networks set to GSM only (no 3G)
Turn GPS and WiFi off when not in use
Turn always on data off
Use a silent or vibrate alert method instead of sound alerts
Turn off your screen whenever you can
If you flashed ENG-BUILD flash the updated RADIO!!!!!!!
Protips
Do several battery cycles every 6 weeks (Charge to 100%, discharge to 0%, charge 2 hours past green LED while phone is off)
Espresso is heavy duty stuff, use a non-sense ROM for additional speed
Charging via USB takes significantly longer than charging via AV
Live Wallpapers will use lots of battery
Use wallpapers formatted at 480x320
Limit the amount of widgets you have to around 5 (unless they are from the same app, like Beautiful Widgets) they constantly refresh and do their thing in the background
I learned most of this thanks to enatefox's guide which I modified to suit the Slide, a coffee fueled mind, and general observations. If you have anything to contribute please let me know and I'll add it!
check general, few threads there on this .. it seems the development section is the hot spot around here..
an APN widget will do wonders, or even juicedefender.
i disable APN until I need it. screen is about 30% always. after everything i do i lock the screen.
on a normal days use (1-2hr phone calls, 30-50min of browsing the net, a ton of text messaging, and streaming slingbox) I'll have about 60% battery by 10pm.
great guide. thank you.
does autostart continually kill those processes? I ask because that long list of bloatware you listed is what is irritating me on my slide and even when I force kill them all they restart themselves every 5 minutes. I have taskilller set to kill them and they come back like the herp constantly.

Autostarts does not 'kill' processes, it disables them from running when certain triggers are triggered.
For example if SpywareApplicationOVER9000 runs everytime an application is installed, and you disable it in Autostarts, then it will not run when an application is uninstalled

Can you write up a quick how to for Juicedefender?
I'm trying to figure out if it's worthwhile to turn off mobile data when the screen is off, and turn data back on when the screen is turned on. It would also be necessary for me to occasionally switch mobile data on even when the screen is off in order to check email. (I'm thinking something like 15 minutes off, 3 minutes on)
Does anybody have any success stories or advice whether I am likely to see any noticeable battery savings by doing this?
I started doing this from when I first got my evo. Just turn off mobile data, you can still get texts and make calls, and then turn it on when you need it. Also turning off background data in settings also adds additional battery, but just enable it when you need the market. I went most of all day with about 80% of my battery still good between it just being off, using the mobile data here and there, and some texting.
Edit: I don't use a tasker, I just use the power widget in my notification, so I can turn on my mobile data on/off with just a tap. And if you're like me you don't know when you actually need it or for how long. So I find it easier and more effective to do it manually.

X2, i use switch pro to toggle mine. Battery drops about 2% per hr while data is of with screen off even when listening to music from my play lists.
I turn off the "always on " mobile data and noticed a big difference. The data turns on and off with the screen.

Over the months I have been an Evo user, I have collected some valuable information that all users should probably know in regards to maximizing battery life. Besides the stuff about 4G and a few specific options, these steps apply to pretty much any other android phone running 2.2, and a lot of them apply to versions below Froyo.
General Lithium Ion Battery Information
^^This link includes stuff about charging, including trickle charging aka SBC (Why NOT to use it, or at your own peril)
My tips for good battery life:
Tips for Non-Rooted users:
1. Turn off all radios when not in use.
(gps, Bluetooth, wifi, data, 4g) Use a widget like the default HTC power widget or Switchpro from the market. The radios of the phone draw power if on even if the user isn't actually utilizing the radio's functions.
To manually turn off radios without a toggle, go to menu>settings>wireless & networks.
Wifi uses less battery than 3G, so use wifi when you can.
**IMPORTANT DISCOVERY**When you turn on your 4G radio, then turn it off, it will keep scanning and turning off all by itself.
The problem is apparently exacerbated by a 4G toggle widget, which causes the phone to automatically turn on 4G at boot. This repeating of scanning and disconnecting severely drains battery life, and sadly, no matter what ROM or kernel you use, there is only one way to fix it:
-If you don’t use the toggle widget, then you have to reboot your phone after turning off 4G
-If you do use a toggle widget, then you have to remove the widget from your homescreens, then turn off 4G via settings, then reboot.
**To check to see if this is happening, download alogcat off of the market. Look for the lines saying: I/Wimax ( xxx): <DC> Try to establish a connection to DC server.
E/Wimax ( xxx): <DC CONNECT> IO error: msg=’/xxx.x.x.x:xxxx –
Connection refused’
Over and over again.
2. Juice Defender is one of my favorite apps. Basically it controls your data for you to maximize life.
More explanations are on their page, search it on the market for free, or upgrade for more features.
Here are my settings for it: Click me
Note that for me at least, juice defender likes to deny apps data privileges whether you allow them or not, so screen on = data on works best for me.
3. I love live wallpapers, and I’ve always been a fan of pixel zombies, but they are really only good for showing off due to their battery drain.
4. Go to menu<settings<wireless & networks<mobile networks<disable always on mobile data.
Product F(RED) said:
To clarify, "Always On Mobile Data", when turned off, lets the 3G modem go to sleep after the screen has been off for 5 minutes. It doesn't interfere with anything like email or any other application that requires an internet connection at that moment because it turns on on-demand rather than being on all the time and wasting battery.

5. Set your screen timeout to something that fits you
This will prevent your phone from staying on when you don’t manually turn off the screen. Also with this, manually turn off your screen when you’re done with your phone.
6. Everyone has that issue where the first ten percent go the fastest.
This is due to two things. One is that these types of batteries stop charging once they get to 100% to prevent damage, and begin charging again at 90%. This means that you could potentially unplug your seemingly fully charged phone at 90% actual charge. The second is number 7.5.
6.5. Use the trick described in this thread, it works.
My idea behind how often you should do it is once a month, if you flash a new ROM, or if you stop noticing the benefits.
This is the calibration technique recommended by HTC themselves. Check it out!
7. Task killers used to be the shiz, but no longer.
Here is the ultimate, in depth, graphically assisted, explanation by the famous Fresh ROM's chef, Flipz. Shortly, in light of recent testing, really don’t do anything but force apps that the android OS needed to be open, and thus didn’t close, to re-open. So try not using them, unless for stuff like trying to figure out why your phone isn’t sleeping with system panel. You really won’t notice a performance difference, and the adverse effects you aren’t seeing will stop
+=+ A good alternative is the application SystemPanel Pro. It has a free version, but I highly reccomend purchasing the paid app. It basically monitors everything going on with your phone's usage both in real time an in terms of usage history. If your battery is draiging fast, it tells you what app was doing it, how much it was doing it, and allows you to stop it.
8. People posting screenshots of the Battery screen as proof of long lasting battery are giving statistically irrelevant information.
See HERE That screen shows time since last REBOOT, not last charge. This isn't always the case, but a lot of people will post a lot of things about battery life, but look for definitive screenshots and testing results before you break down and cry due to the poster's life and yours.
9. I'm sure you have all heard around that your phone isn't "sleeping".
This is referring to the phone's "awake" time, hence the name. When you go to menu>settings>about phone>battery, you can compare the two numbers, "up time" vs. "awake time." Generally, up time refers to the amount of time since the last reboot. The "awake time" is how long the screen has been active. The problem is, a lot of the time, due to the endless possibilities of inconsistencies between apps/ROMs/kernels/phones, the phone will not go to "sleep", drawing power proportionate to the screen being in use when it reality the phone is sitting idle.
If you compare these numbers, and they are the same, or if you note the difference, turn off the screen for a minute, then re-check and they are the same, then your phone is not sleeping.
One solution is to reboot.
Usually, SystemPanel will show an app that has gone "rouge" and is keeping your phone awake.
Uninstall applications/reinstalling them slowly, checking after every install to see what is causing it is one tedious but surefire solution.
Lastly,
Follow these steps that I have discovered almost always work.
1. Reboot phone.
2. Instantly upon reboot, as soon as you gain control, open up some type of monitor/taskkiller
3. "kill all" tasks on startup; about 5 times in quick succession should do the trick.
4. Turn off the screen and leave it for about five minutes.
5. Check the up time v. awake time and see if they are the same.
6. If they are, repeat steps 1-5. If they are different, you are good.
Tips for Rooted users:
1. Try out custom kernels.
By going to the EVO 4G Android Development section of the forums, you can see all of the different kernels being developed. These allow for all kinds of modifications like underclocking the CPU and undervolting, both of which save battery. To see how to use them, read the FAQ's in each thread's OPs.
Here is a great guide to custom kernel's by mroneeyedboh.
2. Use SetCPU in compliance with whatever your custom kernel allows.
This site will explain the basics of SetCPU: http://www.pokedev.com/setcpu/
-Profiles from SetCPU should usually involve these for battery life optimization:
-Screen off at the minimum clock speed for both, with the max raised on level if sluggishness is apparent
-A temperature greater than “X”
-General power related profiles that lower cpu speed at lower battery levels
-Here are my SetCPU profiles: 1 , 2 , 3
-My profiles change a lot as time goes by, because different kernel creators recommend different settings. I suggest reading up on whatever kernel you are using to gather settings.
------------------------------------------------------------------------------------------------------
NOTES:
*Some apps or processes begin to run at startup and keep the phone awake. These apps are not detected by things like spare parts or system panel, unless sometimes represented in the "system" process, in which case its usage will be unusually high.
This shouldn't take more than three repeats, and if it does, you need to factory reset, and slowly add apps back to see what's causing the problem.
___--- When it comes to actually "calibrating" one's battery, there are a couple of methods floating around. The method I first learned is to charge the phone all the way, boot into recovery immediately, and "wipe battery stats". Then reboot quickly, and run your phone all the way to death without charging it, then charge it all the way without interrupting it, and you should be good to go. Do this when changing ROMs/kernels for best results.
----When it comes to people claiming 20 plus hours of moderate/heavy use out of their current setup or other ridiculous absurdities, consider my position: No matter what you do, the Evo battery is the Evo battery. You can tweak it and customize it with kernels, ROMs, and settings, but none of that will turn it into a car battery. The main problem (besides a false sense of pride) that leads to these reports is the misunderstanding of what the usage levels are, so here’s my best summary:
* *Light usage – Phone screen actually on for maybe 4 hours. Things like a few texts, some emails, 20 minutes web browsing, etc.
* *Moderate usage – You watched a few youtube videos or similar apps, sustained web browsing, hundreds of texts, some games. Hours range from about 5-10 of screen on
* *Heavy usage – LOTS of video watching and games, or some high def gaming/movie watching for at least an hour to an hour and a half in total, with lots of emails and texts, browsing, and other app shenanigans
*I’m sure everyone doesn’t agree with all these numbers, but this is most likely a good average of what powerusers think. All specific hourage may vary due to differences in phones, batteries, ROMs, and kernels… Which also means that most battery comparisons are pointless; it’s only what you can improve on that counts!
I’ll update this whenever I see good stuff, people remind me, or I remember/come across things I do.
Hope it helps everybody!

I am the owner of SuttCo. We developed the Locale Mobile Data Plugin (which can be used by Tasker). It has a condition that can keep tabs on your data use and a setting which can be used to shut off mobile data.
I know Tasker and Locale have screen off/on conditions. I don't have time to run any tests for you (busy working on a new plugin), but if you're willing to do a semi-scientific study and report the findings here... I'll comp you a copy of the plugin. Shoot me a PM.
Good stuff

Not to say that turning off mobile data when you're not using it is a bad idea but I've found during my own personal experience with trying to improve my battery life for daily use that using titanium backup to freeze Google Backup Transport.apk is also a helpful solution. Other things that helped are going into Accounts & Sync and turning off background data because believe it or not, that stuff eats your battery up like a fat kid eating cake...hahahaha...Anyways, another tip would be to hit up Display and turn off Automatic Brightness and play around with the scroll until you come to a setting where you can see because I've found that the Automatic brightness eats up your battery too, not as fast but it does! Another thing that I've done is this and although there are task killers that would do this for you....I've decided to do this myself and after using an app such as Facebook or the brand new CNN app, I've gone into Applications and force close them out just to save battery and all of this nonsense I'm talking about has helped me out alot......NOT TO BRAG but using these little tips of mine, I've gone from 2 and a half hours and I was at 70 percent to 4 hours, 36 minutes and 48 seconds and I'm at 68 percent.....and that's with out turning my phone off, that's talking on the phone, texting, checking my facebook, downloading some apps here and there and just leaving it on in front of me at my desk.
Please don't start posting "Oh what, you want a FUC%ing cookie now" and all of this....all I intend to do is help someone by sharing my story....that is all! I got to get my butt to working again...hahahahaha

I have setup a few Tasker profiles to do this exactly. I did this instead of JD because the free JD doesn't do exactly what I want it to do, and I don't want to pay for JD when I can emulate it with Tasker.
The only thing I cannot do, that JD can, is keep data on while there is an active connection. With JD, if you turn off the screen while there is an active data transfer, it will wait until the transfer finishes to turn off data.
According to the Tasker website, there is plans to make a state/event "connection data rate" which would make it possible to do this. But that has been in their plans for quite some time. (I actually happened upon this post while searching for a way to check if there is an active data connection with Tasker.)
Also, with the way that Tasker views an "Open program", the program has to be open in the foreground in order to be considered open. This makes it tough to keep data on when a specific program is open, unless you're planning on keeping that program in the foreground all the time. To get around this, I created a profile that leaves data enabled while I have headphones plugged in, since I have headphones plugged in while using all the programs that I want to have constant data with.
EDIT: here are the profiles, and the tasks that go with them (I also included a profile that turns off the wifi antenna after disconnecting from a wifi access point.)

I'd like to get some feedback from this community on what people feel works and doesn't work as far as Dev Opts and other settings they use to maximise battery life.
I don't want this to turn into a *****-fest - because I personally have been getting on average about 15h + a day as a moderate user and think this phone/OS combo is capable of more.
I'm relatively new to Android and while there are posts in other forums none of them relate to GN/ICS. There are so many settings to play with and many of them might otherwise go unexplored and unexplained to a lot of users.
A perfect example of this is something I read elsewhere earlier tonight in another rant-based thread. Someone suggested turning Developer Options> Background Process Limit to "At most, 3 processes". I gave that a try and in both instances I got a SOD (not immediately but I'm thinking it may not be sound advice after all).
Something else to consider might be stock apps which are safe to disable.
Things that are known to work or have a majority consensus will be compiled into a list in this thread.
To make things easier, try use a path to the setting you're talking about: Settings > Apps and suchlike.
Thats weird, i've been using that setting all day. I wonder if its an app you have installed thats having its process killed and not liking it. Do you get the same if you set it to 4?
I haven't found much except the obvious screen brightness and setting it to 2g instead of 3g - but that can actually be worse if you have a lot of things syncing often and a congested GPRS network.
Oh and I also have Force GPU rendering on, but i don't think that has much effect.
Good idea for a thread btw.
Thanks. I've heard so many people quote the pitfalls of early adoption (now I'm one of them) I think there may be something in the apps point you make. Narrowing it down is going to be tough I suspect.
I use the below setting on my Nexus S to get two days moderate use:
Brightness at 8% fixed
Black still image wallpaper
Bluetooth off
Gps off
Wifi at home
Always sync off
Others sync off, facebook, gplus
Yupe, that suits my usage pattern. I dont like to bebothered with emails and social network notifications. If I need them, open and update manually.
Really big boost on battery life. I expect this is the same or better with ICS.
Interesting. Good tips gogol.
Yesterday/today I managed to get 1d3h out of the phone.
Admittedly, I didn't put the phone through the punishment I usually subject it to.
I never enable BT, and also turn down the brightness on my screen to about 10%. I do leave sync on but try to limit it to necessary apps only and not app contacts.
Yesterday though, I didn't enable wifi at all (didn't need to really, was in the office all day). I made a few calls, sent a few texts and did my usual commute (about 3hours there and back) listening to music (PowerAmp) and messing around with EQ settings a fair bit.
Because I got 1d though, I got in an extra morning (1. 5hours) of music on the way to work.
So overall I'm pretty happy that I can get on average 15h as a moderate user and a ton more as a light-ish user

I updated to the new K6 radio a few days ago and reset the process limit back to standard. I managed 1 day 3 hours with 28% left this morning. I used 2 hours 26 minutes of screen time.
For me the new radio seems to have made a massive difference. I think it has to do with it camping one band/tower for longer and not constantly switching between 3 and HSDPA when there's a data transfer.
I've lately got into developing mobile apps and even though i've promoted this as beta, people seem to be using it, but nobody's reporting back! - same goes for all of my apps, i don't get it...
Anyway, i need real feedback and I was wondering if any folks here with a rooted android could help test this app out, it was made on Kitkat, so while yes, it works fine for me, it may not for you... I've had one feedback comment saying that his modem data was not switching off on lollipop, so i added support for that now allowing him or her to use the app as intended, but after replying via the playstore, nothing was heard of him since... almost suspicious lol

How it works..... read on
How it works, if you're interested!
2 things use up battery power
1. apps that are CPU intensive, eg constantly repeating to connect (this would only happen under malware, as most apps would never do this, it would see the socket it closed/dead and stop and wait until user input, malware would constantly reconnect.. but 99/100 apps will just stop and then do nothing meaning all genuine apps should 'idle' not really using up cpu time....
2. Hardware services, bluetooth, mobile data, wifi, gps, these services are all hardware, so your cpu will switch on each of these services and each one has a significant drain on your battery, go bed at 11pm, by 9am it may have drained 30 - 40% or more... with this app, it will have drained under 1 - 3% depending on your battery (tablets for example should run for days with this app if rooted)
So this app does 2, it first remembers which hardware was on before the screen goes off, so no confusing switch wifi on when wifi's already on (as i've seen on other apps?!) reason why i wrote this because all the other apps i came across sucked really, almost but not quite etc etc..
With this tool, if you're a light user you could quite easily see 60% battery improvement! the bonus side affect of this app is also interesting, for 1, it charges quicker! if you accidentally fall asleep, it will conserve as much power as possible, obviously sms,telephone/mobile network is still running in the background so you can't completely stop a device from draining...
the other bonus side affect was, it kills dead all facebook notifications, twitter, well it would as it disables wifi, modem. 3g, bt when the screen goes off! :good:
1 more feature, if you drop your phone? then what?... take where's my droid, i sms it asking for location... it replies "GPS OFF" and "modem off" simple, send the text message to your phone with "on" without the " " around on, and the app will disable itself so it does not switch off the services and then at the same time it enables Wifi, Modem Data, Gps, Bt pretty useful huh... then on where's my droid, you'll get GPS combined with AGPS data from mobile data giving you pin point accuracy, as soon as you get the data of where it is... type in
off (to turn this feature off) or
on (to turn on all your services)
It also disables itself taking calls...
It has a smart check feature too, let's say after you switch the screen on and for some reason wifi failed to switch on ? after 3 seconds it will then check again to see if wifi is indeed on... if it's not on, it attempts to switch it on again...
Feedback is greatly appreciated so i can support a larger range of devices.... thank you for reading! (Suggestions, welcome!)
So basically what your device is and what's not working (along with build version, lollipop/kitkat etc) and i'll see if i can find a way to add it in to support your droid! - one more thing, i've been releasing updates like a crazy woman collecting cats lately and even though it does all this it's only supporting "Extreme power saving option" come tuesday i hope to have that sorted out so that every few minutes it can wake up to check for twitter/facebook messages for all of those who hate the sound of a phone being blissful quiet
if you're rooted and it does not look like that in the video [top of screen] (not the interface, but the services, i've already updated the UI)
anyway, help me to make it better for you...
One more thing, there are no push notifications, no popup adds, no huge banners, all my apps have one tiny advert to help support the countless hours of programming i'm putting into this apps, with each upgrade i aim to make them more stable and more usable, and i really need peoples help and support even if that is criticism - it's "beta" but i'm almost ready to bring it out after i add the wake up services....
Nobody has a rooted device?
Unlike other battery savers... it really does work
I have had the Captivate Glide for little over a month now. It was the rooted rogers version but I flashed AT&t's rooted ICS on to it.
Major issues were battery life and GPS.
Without changing any software I wanted to solve the issues or make them tolerable at the least. Probably better ways of doing this, but this is what works for me.
I assume everyone else is like me and downloaded tons of apps that we like. I personally have 30 downloaded with some form of Google being responsible for at least five of them. I also synced my google account, as well as my outlook account and skype account.
I do not game on my phone I prefer the console style of gaming but I digress.
Simple battery life can be saved obviously by closing or backing out of applications when not in use. You must be avid about this in order to preserve battery life. If you have not altered your ICS it comes with an "Active Applications" widget that makes this simple and easy. Within that widget is an even better function that allows you to clear memory on your ram. Do that for superior battery life as it will close down any program running including back ground processes.
You should also have widgets that allow you to toggle WIfi, and GPS, Bluetooth, brightness, screen time out, sync, and settings. <Extremely helpful in saving battery life. Wifi should be used whenever possible. If your phone is running processes that use data and it probably is, its better to use Wifi for your battery. Turn Wifi off when you can not secure a connection because the phone searching for wifi to connect will eat your battery.
Turn off GPS when not in use. If using an app that likes to have your location you can keep GPS on but turn it off when not directly in use it saves battery like no tomorrow.
Screen brightness is also a huge factor in battery Life. If you Go bright you die, simple as that. Make your screen as dim as you can but still comfortable to see depending on what you are doing. Again the widget makes this super fast and easy but you can go into the settings and adjust this by percentage if you are particular. Other wise the widget allows Bright, half bright, auto bright, and no bright. No bright will save tons of life so learn to see in the dark haha.
Screen timeout at 15s will save tons but can be annoying if your in the process of using your phone. I uses it and just tap my screen if I need it to stay light but trust me it gets old fast but so does a dead battery.
Go to your individual synced accounts and adjust the sync intervals to specified times if possible. Usually find it once you open whatever account and go to its settings. That gives the battery some life in between syncing which uses data and eats battery.
Go to settings and toggle system power settings. This Saves a huge amount of battery life and I have no idea why. You may be tempted to customize but don't. The system power saving is far superior from my experience so far.
One last and final thing to save battery life. The Google Play Store. It runs a ridiculous amount of Background processes. Go to settings, then, data, find the play store and click it, scroll to the bottom and restrict the background data. You will have to turn it back on in order to use the play store and some other apps which leads to my next topic...
GPS
This captivate glide has a notorious rep for being ****ty in these here forums. I am here to tell you its not all true. I am not a software guy as you can see all of my advice is simple common application usage advice. I previously had the SGH-I827 and its GPS was spectacular so I found it hard to believe the captivate glide GPS would not perform well. In fact when I began to use it, it did not. It was glitchy and unreliable. Terrible at best. I thought I was going to have to buy another phone or do some software stuff I had no clue of. I was patient.
And for myself I figured it out.
Everything you do to this phone is reflected in its functions.
All the things I suggested to save Battery Life impede the GPS of this phone. Take that in...
I started over from scratch resetting back to factory settings. (leaving the Stock rooted ics). If your google account backs up all your apps they will begin to re download immediately once you sync your account again, BUT STOP IT!
Don't let anything Upgrade or Download to your phone automatically. This is crucial.
Google maps upgrade must not be allowed. Instead use the current version that comes with the ice cream sandwich OS. (includes the navigate button we all like as well as the places icon) Everything else can then be downloaded or upgraded in the play store manually.
Now, for the tricky part. you have been saving battery life using all the propper previously mentioned techniques but now you want to use GPS. First thing you need to do is uncheck system power settings.. Then allow google play services to have its background data back. Settings, data, google play scroll bottom yea uncheck it. Turn your screen timeout to 10min. Now toggle GPS back on. But wait one more thing, Clear the ram. All done in that order Now when you go to maps you should get a lock in under a minute and it will be reliable. No way of stopping GPS from consuming a ton of battery but if you dim the screen and charge it while in use you will see battery life gains instead of losses.
Thanks for reading my personal usage experience so far. I have yet to take the update to GPS to see if it still works in the same fashion because I am a coward and I like my GPS right now. Let me know if anyone experiments further. With the rooted ICS OS.
