Help Battery life and battery management

Has anyone purchased the 1800mAh or 2000mAh from the ebay? I was wondering if the difference between 1800 and 2000 is noticeable?
 
Wow! I just spent 20 minutes putting together a friggien response only to mistakenly leave the forum page and lose what I wrote.

In a more abbreviated version, the Sprint website below talks about what I think is one of the bigger battery killers, that being Google Talk. Access the application and turn OFF the auto sign in and then sign out.

I also do not have the locate servce on or the power management turned on.

I have installed an app called Brightness level, that is on my homescreen to give me a two key press brightness setting between 0% to 100%. I normally keep it at 25% until I go outside.

I keep my GPS on, because it only drains battery when you see the little Satellite antenna icon. I keep BT off and Wi-Fi off until I need it, and use my phone about like you describe, and I get 24 to 36 hours easily of use.

I found that the Marketplace app called Open Signal was always running in the background and using my battery, because after I uninstalled it, my battery life got better.

I also shy away from programs like Lookout. For they require way too much access to my phone and they seem to really drain the battery.

I keep a widget for Running Applications and the native Task Manager on my left homescreen, basically for easy access. There are many services that run but don't consume battery juice, but some that do, so by looking at what is running, you can see a pattern of what non native program is always running, turn it off or uninstall it and see if that helps your battery, then if it does, decide if you want to reinstall it.

I have installed Battery Indicator for the 1% battery life indication and for the Fully Charged alarm it offers. That way I remove it from the charger immediately after it is done charging, which prevents the quick 10% battery life drop people complain about all over these forums.

About once a month I do the following charging instructions, and I love my battery life.

Fully charge the phone while on, until my Full Battery alarm goes off.
I unplug the charger, wait for thee charge light to go off, then power down the phone. I immediately connect the charger and charge it until green. Sometimes it takes a few minutes to 15 or 20 using the 110V power outlet charger. After it is green again, I unplug it and power the phone one. Not sure if you know this, but using the USB port on a computer takes twice as long to charge the phone due to the lower power output. I can get my phone charged from roughly 25% to full in rougly 3 hours.

Have you noticed that your Awake Time and Up Time are pretty close in duration? If so, that could be the Google Talk or another program doing that.

I have found out that when you charge the phone with the power on, the phone counts that charging period as awake time, which is another good reason to power it down after charging it with the phone on. You get a fresh Up and Awake time counter.

The bottom line I have determined is this. Many phones get a bad rap because people get a phone, half ass charge it, immediately install a bunch of apps and then expect the phone to perform right.

Out of the box, the battery should be charged until full and then discharged ONLY until about 25 or 30%, fully charged again, discharged to 25 or 30% ONLY, repeating 3 to 5 times or a bit more, before the battery can even be considered optimal for normal use.

Happy 3VO'ing!

I use about 2 hours of phone calls per day if not more, maybe 60-100 texts (total on send and receive), random web browsing, market downloads, google searches (maybe about an hour all told). Then after work random phone calls and texts. I unplug at 7:30 AM and I generally plug in around midnight with anywhere from 30%to 10% battery left depending. I keep GPS disabled and always on internet unchecked. Whenever I am at home or the office I am on WiFi. We have unofficial 4g here in downtown New Orleans and most days I will use about an hour of that at the gym watching a movie streamed from my house using PlayOn. Somedays I do eat through my battery like it is nothing and I would bet you could do the same with the iPhone 4 (which all my friends complain has terrible battery life and very few tweaks to make it any better) but for the most part my phone gives me enough juice to last as long as I do in a day (from waking up to sleeping). I am not rooted and do not use task killers (pointless for any 2.0 and above Androids regardless of what any proponents say).

Depends on usage. Install Battery Monitor Widget from the market. Watch your average usage. Let's say you average 300 mA (miliampre) constant. So, over an hour, that's 300 mAh (miliampre [per] hour). So, at that rate, increasing from 1740 mAh stock battery to 2000 mAh would gain just short of 1 hour average use. So you would go from 6 1/3 hours to probably 7 1/2 hours usage. If you average more or less, times increase or decrease, obviously.
 
You might want to check to ensure that you have your Enable Always On Mobile Data UN-Checked.

Also ensure you have Google TALK setup to not auto sign in and that you sign out before you exit after make the auto sign in change.

i woke up to find my battery at 56% from 100 after only 7hrs off charge. Display eating 60%. What's weird was that the phone was sleep during those 7 hours.

I disagree with the Gtalk assessment. If you're constantly on 3G, then perhaps it does. On wifi, the battery loss to Gtalk is not as noticeable, if at all. I use Gtalk as a primary communication tool to friends. It came from being on VZW with limited texting. My battery lasted from 6 to 6:30 AM (when I took it off the charger depended on the morning) until I went to bed at 10 pm. I would stream Pandora a lot or listen to an audio book. Maybe play a game or two. At the end, it was usually pretty low, maybe 15-20%. Every day. Using Gtalk throughout the day.

While I haven't been able to fully replicate that on my 3vo, I'm getting close. I was listening to my audio book yesterday and doing some talking on Gtalk and my phone lasted all day and ended up with a 30% or so charge. I even used 4G at times throughout the day with no charging. Now, I don't get the beginning of the day to end of the day charge like I did with the DX because I use this phone more often. But that's the price to pay, isn't it?

But, YMMV.
 
You certainly have a good point with respect to GTalk and Wi-Fi, which I have no experience with. Those users with battery life issues, should consider using Wi-Fi in general more often if they can, as I understand there is less battery drain as long as the device is not constently searching for a Wi-Fi signal.

I would also suspect the reason why Sprint considers GTalk such a battery consumer is because it logs on automatically by default. Any IM program (AIM, Trillian, Yahoo Messager and BBM if it ever comes to Android) would be detrimental to battery life while on anything but wifi. Because it will keep the 3G radio alive. And that's the real power drainer: Not letting the 3G radio sleep/go inactive.

But, by all means, it is a good thing to raise awareness about how Gtalk is on by default, especially if people don't plan on using it. What kills the battery the fastest is between the display, CPU usage, and the radios (specifically 3G/4G). Low power radios like wifi and bluetooth have a much smaller impact on battery performance.
 
If I am recalling right, when GTalk is set to auto sign in and you have your mobile network set to always on, the Up Time and Awake time of the phone, remain pretty much equal.

With those settings off, I can have 24 or 36 hours of Up time and only 6 or 8 hours of Awake time.

If you rebooted WITHOUT the fast boot option checked, then your Up Time and Awake time start over.

If you charge your phone with the phone on, the awake time will equal the Up Time because during the charging, the phone is considered awake. I have not figured out anyway to stop that from happening, except charging it while off.

Maybe. My awake time is lagging behind up time by 3 hours and I rebooted sometime last night.

I never turn my gtalk off and my phone always sleeps and I dont have any battery drain issues.

Then my phone would have more than 12 hours up time. The time roughly corisponds with when the time rebooted. I enabled fastboot about a week ago an haven't pulled the battery in the while. So I can't see how a fastboot reboot does not reset the timer.
 
Shipping for Seidio EVO 3D slim 1900 mah battery began today (7/15). Now
Seidio is shipping both 4000 mah Extended battery with door and slim 1900 mah battery for EVO 3D.

Thank you for the patience.

Definitely not equal.

I run GTalk all the time and do not ever curb my mobile data.

I just looked at my phone now -- uptime 35:38:00, awake time 24:57:00
 
So your comment below of "then my phone would have more than 12 hours up time" relates to what? My comment was directed towards the Awake time, not Up Time.

If you turn off Fastboot, shut down your phone, plug in your charger and then turn on your phone and let it charge, your Up Time and your Awake time will be the same.

Is it possible to still get push notifications and widget updates of I un-check always on data, but leave auto sync on?

Also, does turning off always on data interfere with Pandora or other music streaming apps?
 
I guess between buying a larger battery or a new SD card, I'll go with the SD card for now, since I have a total of 4 chargers for practically every scenario I'm in (stationary or on the go). So I guess the need to prolong the power in my 3DVO isn't as big an issue as I had thought.

This isn't to say that I wouldn't get one at some point though. It would certainly come in handy while travelling, or embarking on an adventure where I'm away from an outlet or my car. But I don't foresee either of those events happening anytime soon, so the 32 gig SD would be the logical choice... For now.

That would explain why your Awake time and Up Time are somewhat close.


Try fully charging it, the power it off and back on with out Fastboot checked, then turn off the always on mobile data and see how much more battery life you get.

I never said my phone doesnt sleep lol... I said it sleeps fine.

It always screwed with some of my apps and thats exactly why I never do it. There would be times where my email would be sporatic and wouldnt come until i turned on the screen and others where it would come through fine. Didnt work well for me. And it killed my issimo push notifications.
