[Samsung Captivate Glide] karaevelli:
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.
