    How did you get that to happen? Mine is always in 1X mode even though I am in a strong 3G area. Did you swap out with Verizon?

    Ooooh, wow, you're so smart. You have an education in electrical engineering. Lets all bow down. :rolleyes:

    As was posted above, it's not about education, it's about desire / needs / wants. Do you think most of us didn't understand when you posted the first (or second, or third, or started your own thread) that maybe you were right, and that turning off the mobile network would save battery life? I think even the non-engineers of us here (BTW, I have a Masters of Engineering, thanks) could have grasped that subject. So since your engineering education has obviously killed all your common sense, let me spell it out as others have done:

    NO ONE WANTS TO DO THAT.

    Try sending an email without the mobile network on and see what you get. Hmm, a big fat error message that says "This function requires connection to the network. Please enable wifi or the mobile network."

    So, if you need to get emails in a timely manner, you're hosed. Some people communicate actual useful information via email, you know? Like my wife saying: "running late, can you pick up our son?" Wow, she might be a little steamed if I said "sorry honey, I didn't pick him up because I had the mobile network disabled on my phone to save the battery life. I guess I'll have to go back out and get him." Or my boss saying "did you get my email about changing the meeting from 12:00 to 9:00? Yeah, that would go over really well.

    So instead of harping on the rest of us being technological philistines, consider someone else's situation before taking the high and mighty approach.

    Anything clicking for you now?

    Yes, your point about the internet and facebook and all that has some validity. But you can't get email without the mobile network and for some of us, email isn't a luxury.

    LOL

    I got a phone for someone who constantly shuts off the internet capabilities of there phone:

    It doesn't have color, but thats just a silly feature that drains battery. I mean, look at all those buttons you get...amazing!

    haha, I had that phone years ago along with many many others ...like these between '94 - '96. Oh the memories....

  6. I will explain this one more time...

    There is only ONE cell radio in your phone.

    Your phone has 214 mins of talk time. During these talk time mins the exact same radio is used as when you have the "Moble Network" on. This means you have alittle over 3.5 hours of usage of heavy data transfer.

    When you have "Mobile Network" switched on you are basically using "talk time" mins since the cell radio is powered on.

    Point is.... "talk time" and "Mobile Network" (aka your data connection) time are the SAME THING becuase they use the same radio. This is common knowledge in the cell phone world.

    How ANYONE bought this phone thinking there was some kind of magic network connection that does not use battery power is laughable.

    right and wrong, total talk time is not equivalent to total mobile connection on time, not even close.

    gmail is pushed to your phone, therefore the gmail server tells you phone there is new mail. it takes seconds to get that mail, this happens whenever you get a email. So if you get a astounding 100 emails a day, that would be equivalent to 100 seconds a day of talk time.

    other services that use mobile connections are not "always on" if you open browser and load a page, that load time is using "talk time" but when the load is over it is done and off of talk time.

    this goes for any app that uses mobile connection, they are not always on and always using your battery or "talk time"

    basically when you see the 3G symbol in your notifications pain and it shows the up/down arrows, that is uing "talk time" or the mobile connection. sit and watch it for a bit, you will see it is not always on, or even close to always on.

    get educated ;) im giving this out, free, all day Grim
  9. Again you simply dont understand that the radio is ALWAYS on and in contact with Verizon network. Your radio is constantly sending "alive" signals and information to maintain data connection. There is ALOT more going on than you know. Also as I said before you have 214min of heavy data transfer before your battery goes dead. Battery lasts for a day or two with the "mobile network" on becuase its not transfering heavy data all the time but.

    The radio is still powered on and constantly sending "alive" signals and other information to Verizons network to maintain data connection regardless if any apps need the connection or not. This is what people simply dont understand.

    Again you only have 214 mins of heavy radio usage. Turn the radio off when not needed. IMO the Eris actually gets GOOD battery life considering how long you can have "Mobile Network" and the cell radio powered on.

    Education is key to understanding. Dont blame the phone becuase you dont understand whats going on.
  10. I would also like to add that my battery meter has NOT moved at all in the past 12 hours since I have had Mobile Network off. Not even one notch....

    Yes THATS how much power you will save!

    Im not gonna get in a pi$$in match with you, I have worked and hacked cell phones, modded and admined cell phone forums, and worked with technicians for many years.

    although turning your mobile connection off might save you some battery, it is not neccessary, required, suggested, or merited in any way.

    Your advice is not sounds advice, it is bad advice. period. end of discussion. If turning the mobile connection off on your phone is the only way to be happy with battery life you should stop telling everyone to do it and start writing the manufacturer to tell them there is something very wrong with their smarthphone QC.

    There is an ignore list feature of the forum here, I encourage everyone to put it to good use.
  12. Simply too funny!!!! There is NOTHING wrong with the phone. They CLEARLY stated 214min of talk time. How do you not understand this yet???

    Wrong. The radio ALWAYS pings the network every 2 to 3 seconds unless the radio is shut off. If you turn the mobile network to off, it will ONLY check for calls and txts, but it WONT check for email, updates, etc..

    And evdo data usage is much more of a battery hog minute for minute compared to when you are actually making a call.

    Please explain how to use this feature before I go bananas listening to this mis-information being foisted upon us all.

    As an admin myself I kinda broke my own rules and was mean, I apologize.

    It is not nice or appropriate to annouce who is going on your ignore list, I'm sorry.


    ignore list options are here decaf.

    Correct. Every (I believe it's) 3.5 seconds the radio will "ping" the tower and say "I'm here" to check for new voice calls to ring through and for SMS. At that same time it will verify that the data network is available. It is done simultaneously and takes milliseconds, therefore doesn't make a drastic effect on battery. What does is the other data features the user may be running (Weather widget, gmail sync, email polling, etc). Because the voice and data both use the same radio chip it doesn't "double dip" on energy drain.. it's the apps.

    But Grim, believe what you wish. I'm glad that works for you and you're happy with your results/situation.

    Shame shame, Now I'm gonna ignore you :p Just kidding

    This information will help me in that I have the internet at home (with a bigger screen obviously), and I'd rather surf the next on the computer than my phone. So, I can turn off the mobile connection when I'm home and hopefully some better battery life will be the result. But I do agree with the overall feeling that the way Grim delivered this information was pretty unnecessary.
  18. Your battery life will TRIPLE. I still have 60% battery life after almost 2 days now and I have been using the phone for a few calls, mp3 player, browsed the web a few times, played around with home screen setups, TXTing, ect.

    People are throwing away thier battery life for no reason by leaving Mobile Network on.

    I came from a BB too and the battery life was amazing but that is one thing BB's are really known for. In my experiance the Eris can have a pretty decent battery life if you take the right steps. I have everything running with the exception of GPS and WIFI and I use my phone and ton seeing that I work in a cell phone store and I get a good full day out of the charge. These new phones multitask like crazy and the battery dies alot faster because of that. But just like any phone if you dont watch whats running in the backround the battery will die.

    My Eris came with a charger thingy and I even bought an extra charger thingy for my vehicle so that when my battery is low, I simply plug it in! It's been workin' for me for years now!

    I am actually doing exactly what Grimster is doing, and get quite decent battery life out of my Eris. This won't not work for everyone, but if you are in a situation where you phone is running low on battery, and you are no where near a charger, turn off "mobile network" is an attractive option. A working phone is much better than a dead phone, even if it only does voice calls (and sms).

    The on-demand usage won't work for everyone. It's a bit troublesome. You have to turn it on/off as needed. So you have to judge whether the extra battery life is worth your effort for doing so.

    But for me, it makes perfect sense. When I am at work, I am ALREADY on the computer, with full internet access. When I am at home, I also have full internet access, so I don't really need my phone to on the net 24x7 sucking away battery doing pretty much nothing. When I do need to use it to look up something, check email, etc, I just turn mobile network on. It just takes a few seconds for the phone to catch up to the latest email, etc, and while it's doing that I am already check stock, weather, etc.

    So for me, it's a no brainer. I get the smart phone for the ability to access internet anywhere, especially on trips or when I am outside. Knowing my phone will have battery when I need the internet access in those situations is FAR more important to me than having it pull email/data every 10 minutes.

    But, in both locations you can keep it on the charger so it doesn't drain as it is. I keep the USB cable with me at all times so at work I can just connect to my PC and play music
  23. That sucks. Who the heck wants to worry about thier battery every 10 mins when you dont have to...further more you are missing the point here. You will be letting the radio drain the battery for no reason.

    wildgoose is spot on and actually understands whats going on here.
  24. CalifJewls

    CalifJewls Active Member

    Oh Grimster, no one is missing the point here and everyone "understands" whats going on, if it works for you then have at it, but don't tell everyone they are not intelligent for choosing not to do as you do!

    You really just don't get it do you.

    Please stop characterizing everyone who's leaving their mobile network on as uneducated buffoons.

    We all get what you are saying.

    Some choose not to do it.

    You are entitled to your opinion. Stop forcing it upon people. What you are saying does not work for all lifestyles. It is good that it works for you, and we all understand that it WILL reduce battery drain. But again, not everyone wants to have to deal with that.

    Thank you.
