    I have a couple of questions I was hoping someone could answer. I have a hit and miss wife connection at work and my 3G connection is horrible and we don't have 4G here yet. If I turn off my 3G and wifi will I still be able to receive text messages and calls?

    Now that I've actually had Friendstream turned on I'm not a big fan and would like to turn it off but can't figure out how. Anyone know how I can do this?

    Finally I have a trip coming up in which I want to make sure my phone doesn't die so I'm considering buying a bigger battery (ie. 1900). My understanding is a bigger battery won't damage the phone, am I right in my understanding?

    Thanks
  3. After 120 hours of being unplugged I'm throwing this EVO 3D on the charger with 27% left on the battery.

    Brightness = 1%

    I have experimented with auto, 100, 75, 50, 15, and 1(or whatever the lowest setting is) They all weigh significantly on my battery if the screen is on. I can run a million apps while the screen is off and it won't eat a mA, but as soon as that screen pops up.......................................

    Is there a short cut button for turning off 3g?

    There's a widget included by HTC. Otherwise you'll have to go into settings.

    But if you want to, there's an app called Quick Settings that works well.

    Under "widgets" look in the list called settings, for an HTC widget called "mobile network".

    Also pull down your notifications and the bottom quick settings tab Mobile Network is there. I am trying to get into the habit of using those cause on my EVO 4G I had 4 toggle switch widgets on one of my screens.

  11. I used airplane mode for 14 hours of those 120 hours. Airplane mode wasn't even a factor, especially if you have a network to roam on which I did during those 14 hours. Don't make things up if you lack knowledge about the subject matter.

    No need to respond further to Panthro - until he returns under another name and we ban him again.

    I just went to take my phone off the charger to leave and it's green and says 99% I went to do some other stuff around the house came out and it was on 97 and i just saw it drop to 96 is it cause my screen is being kept on while charging? Guess I'll take that setting off.

    I just want to chime in with a sorta public service announcement on battery stuff.

    First, the charging circuits are known to take a while to calibrate. The bumping thing can speed it up, but overdone, can damage the battery.

    This gives the illusion of the battery not accepting a full charge. Those owning the 3vo long enough for several charge cycles have likely noticed the charge light going green more readily - the charging data are becoming calibrated.

    Once at full charge, the phone does not run off of the charger - it runs off of the battery until it hits its charge point again, and then starts re-charging. This is born out by the graphs on the other site showing a long charging cycle - look closely - it's the lower 3/8 of a sine wave. Left running long enough, you'd see the sine wave - the rollercoaster graph some of you may have seen me describe in other forums. The charging point is known to vary by model but typically be between around 92~96%.

    When you take your phone from the charger, its true state is not available for several minutes - giving the false appearance of rapid drop.

    There is no such thing as trickle charging for these beasts - trickle charging would cause the battery to ignite, so it's disallowed by design.

    ~~~~~~~~

    Pull down notifications, tap right tab - Quick Settings - turn off Mobile Network - that's 3G.

    ~~~~~~~

    There are good monitors to help you decide if you have a rogue app or bad settings eating at your battery. If you're new and have missed these, some of the popular ones are (free in Market) SystemPanel Lite, Android System Info (Electric Sheep), and System Tuner. Please use them for monitors only, not task killers.

    If my previous post didn't show that I lack quite a bit of knowledge on the subject matter I'll show it again with what some may think is a stupid question. I saw this advertised on Amazon and it says they are batteries for the Evo I was wondering if it should be fine to run on the 3vo. Any input is appreciated.

    Thanks

    Those say EVO 4G and TP2 but yeah I bought the same thing off Ebsy for my EVO 4G and now for my 3D. I just got 3 batteries and a wall charger similar to that for 16 bucks. The ones for my EVO worked ok.

    I'm still glued to a charger. I don't understand how you all get this excellent battery life. One 10 min phone call alone will drop my battery almost 10%

    Where are yall buying the extra batteries and spare battery charger from? I looked online but didn't see any sites I would feel comfortable buying from. Thanks

    EVO 4g battery would not work in the 3D. Two different sized batteries.

    What is your signal strength? If it's less than 4 bars, I've found it does drain battery. Also, do you have 4G enabled? Even worse battery drain especially if not at full signal strength.

    The low signal strength drain is the biggest problem Sprint has, I think. I've had this problem on every Sprint phone. I wish someone would make the "use all available power to search for better signal" algorithm a bit less aggressive. In fact, if I have poor signal AND am doing data over 3G, the phone gets hot! Turn on WiFi if you do this (if you can). That's been my solution for years.

    I get 16+ hours on my phone, now, with push mail on four accounts, 15-minute updates on other accounts (twitter, some email, etc.) <10 minutes of voice, a few texts and 1+ hours of web use (not downloading that whole time, of course). At this point, I'm a bit under 30% charge, on average... extrapolating (which is not quite valid, but whatever...) that's 22 hours. I'm not playing online games or watching movies, but I do watch a youtube video occasionally, for example. I'm not trying to save battery, but using the device as I think I should.

    Finally, here are some screen shots clearly showing what others have said (including me but now I have photos):

    1) Notice what happens as you get to 100% charge:

    2) Here's my last three days of usage to "prove" what I'm saying, above:

    Thank you for your reply. Inside my home I have regularly 3-4 bars. I've been on WiFi all morning. Phone has been off the charger for one hour and twenty minutes. My battery is down to 75%. I've made a 10 minute call, web, and about 15 minutes of online poker game.

    Well, something odd is going on (3-4 bars is OK, but using WiFi is still the way to go to keep battery drain to a minimum in my experience).

    I'd suggest getting SystemPanel (search Android Market for it) and then run it for a few hours. If you see the battery diving down, you can list the applications using the CPU and often find the one(s) that have spikes during that time. You can also watch your network use to see if something is always on consuming a bunch of bandwidth/power. Maybe that online game is keeping a connection open? Just a thought.
