How is battery life on Froyo EC05 so far? *poll added*

[Mobius360]

So I have to say, I don't think I've ever gotten the battery life that a lot of folks tend to report... 24 hours? Not on my Epic! My question would be: are people who get this awesome battery life using 4g? I am... and maybe that's my killer? The only thing time I turn off 4g is when I am at home - where I use wifi... would I be better off turning on 4g only when I want to use it? It seems to go to sleep (shows Zzz in the icon) when not being used, making me think its not draining me when its on but not active...hmmm.

So if I look at what is eating my battery, I usually see something like "display 98%...cell idle 2%"...Android Assistant doesn't seem to show any programs draining everything...I have my brightness at 35%-and i'm not keen on lowering it! What good is having a sweet amoled screen if you can't see it?

4G turns off automatically when wifi is connected. I do believe 4G is ruff on the battery though compared to 3G.

I don't get great life either. I make sure drmservices is off and do the airplane mode toggle once in awhile. I have minimal background services running and my screen at 12% (I am indoors typically).

Is Qik always running in the background now for you all? Why would that program run all the time?

Also tried Beluga and it runs all the time too. I guess I understand this one so you can receive a message. Maybe that's why Qik does it too, but I didn't notice Qik doing this before.

my experience is: YES, 4G only when you want it. akin to how battery gets killed when looking for a 3G signal, I've found that the 4G snooze is doing the same thing

I have my brightness at 35%-and i'm not keen on lowering it! What good is having a sweet amoled screen if you can't see it?

screen brightness has a lot to do with how many times you wake your screen in the first place.... once an hour... once every ten minutes... every minute? it takes a lot of energy just to get the screen on, more than you might imagine.

My phone has been dying quickly and has preformed worse than 2.1. I am not sure as to why but It needs to be fixed!

I assume everyone is following the basics of battery savings. Turn off carrier data when it is not needed. I think juicedefender does this for you automatically. I'm on wifi 2/3 or more of the day which means that the carrier data is not being used which helps significantly since wifi uses less power than the carrier data radio. My screen brightness is set to auto and power savings mode is turned on. Without either I used up more battery for the screen. Screen time out and key back light time out set as low as possible. Only use vibrate for when you need to be notified but want to avoid disturbing others. Reduce the frequency of frequency based syncing such as checking twitter, pop email, etc. Minimizes the number of active widgets sure they may be neat but some are power hogs. Kill the background processes for widgets you aren't using. This is one of the biggest things that improved battery life for me. Despite the fact the widgets are not added to any launchers some will still load at start up and others load when you open the app and remain loaded until killed. I added juicedefender to save additional battery using it's default setup I appear to get up to 20% more. All of this gives me between 24 and 36 hours on a single charge with light to moderate use. Heavy use about 16 hours. Less if I am making or taking a lot of calls or long calls. 2 hours on calls will use up something like half the battery which would cut it down to about 12 hours without any other use. Outside of that using the built in battery use and android assistant's battery use tracker you can identify what apps or activities are using up the most battery and adjust things accordingly. Have I missed anything?

Would anyone know if the Pandora and Winamp widgets (4x1) drain battery even when not in use?? These are the ONLY widgets I have on my phone.

Battery seems terrible to me. Performance is improved though, particularly with the native Facebook app.

 

[MrVaNupe]

Since getting the update last night, I have no unusual drain of the battery.. Hopefully it will stay that way...

Would anyone know if the Pandora and Winamp widgets (4x1) drain battery even when not in use?? These are the ONLY widgets I have on my phone.

I don't have winamp so i can say for it but I do have the pandora widget and I'm almost never listening to pandora. If pandora (likewise slacker) shows up in the battery use list in android assistant it is less than a fraction of 1%. Typically is shown as 0.0% which I assume means less than 1/100th of a percent since others list in format x.xx%. Considering all the widget does is show info of the currently playing song and provide playback related controls it would be expected that other than the ram it uses (probably minimal) it is using no system resources (processing power) when pandora is not being listened to.

On the other hand widgets that link to display twitter or facebook stuff or other periodically update info those would consume battery how much I have not bothered to check because I don't use those kinds widgets other than the weather channel widget from the weather channel app. It uses at least 1% (and probably less than 3%) of a full charge assuming I understand the battery use percentages feature. On 2.1 (the preloaded version that came with my epic) I had about 6 or 8 of these kinds of widgets loading at startup. Killing these off appears to have indicated they on average used about 2-3% each. Since I don't intend and didn't use them I don't have better info than that.

The top items listed in the battery use for me are as follows with typical estimated percentages:

display -------------- 20% or more (heavy use this exceeds 35%)
standby ------------- 20% or more (the lighter the use the higher the %)
calls ---------------- up to 10% (typical day, heavy use at least 25%)
idle ----------------- 10% at the lowest (the lighter the use the higher the %)
sprint protection app - up to 10% (thinking about uninstalling)
wifi ----------------- avg 5% (up to 10% moderate use or more if heavy use of data)

dialer (avg 1-2%), ADWlauncher (avg 2-3%), twitter (avg 1-2%), google reader (avg 5%), market (avg 1-2%), swype (avg 2-3%), and other non game apps that I typically use on a daily basis up to 5% each.

Below those is typically 10 or more items that use less than 1% including the following: email (google and yahoo mail apps: 0.5% or less each), norton security beta (0.75% or less) juicedefender (0.1%), android assistant (0.03%), battery indicator (0.03%), and misc other stuff typically small fractions of a percent.

The phone lags less but batt dies quickly....

First full day with EC05 - using a combo of *#INFO*1111# code and the System info:

15 hrs 45 mins - 16% battery level
Display 77% (1 hr 10mins)
Cell Stby 14% (15 hrs 44 mins) (TWS 2%)
Phone Idle 7% (14 hrs 39 mins)
Voice 3% (4 mins)
Wifi 2% (43 mins)

This was a little lighter use than normal, but the battery was lower than normal.

I believe my battery life has improved just a little bit.... I am pushing 35 hours with about 35% life remaining. This is with a 3500 mAh battery.

I have never gotten more then 4 hours screen on time with any update or any custom rom. That is what I would consider heavy use. ;-)


Then again I went on a carribean cruise for a week running bonsai 3.0. I put the phone in airplane mode and kept it inside our cabin and got 6 days. Yes DAYS on one charge.

So in my opinion battery life is directly related to screen on time and signal strength.

 

[cluefree]

So just curious... with Froyo, are applications such as Juice Defender useful - or does it just fight against the OS? I've read that EC05 is much more active about controlling background services/data... The last thing I want is to spend all my battery turning on services 200 times because I've got an app turning them off all the time...

 

[GrooveRite]

I am def losing battery life more quickly than on EB13. Even when my phone is idle, its losing battery much faster than previous OS versions. Yes, I am aware of every app that I have installed and running in the background.

I got the update on Monday I believe. I've been seeing android.iqd running rampant at times according to System Panel. It would be sitting at 100%; only way to fix it would be to restart the phone. The other issue would be with the suspend process using consistently more than normal for some reason.

Gotta say I'm getting tired of nannying the battery.

 

[bfguns]

battery life is less. just on my drive into work all this week, which is a 10 min drive, battery drops down to 90%. I've done the usual things.

Time on: 8 hours 25 minutes.
Time without signal: 50%
Display Time on: 31 mins and 8 seconds. it's 1:40pm, phone has more or less just sat on my desk. maybe a total of 20 text messages, 10 mins of surf time, and my battery is down to 25% wherehas before the update, i would still be at 60%. Mind you, i'm right in the middle of downtown Silver Spring, MD. both 3g and 4g coverage, and there's a sprint store 3 blocks away. full bars on my cell.

i'm not happy.

 

[dominick]

Time without signal: 50%

that's the problem right there.

i'm at metro center with a decent 3G and intermittent 4G signal, and i'm only down to 60% having took my Epic off the wall charger at 8:00am (downloading and reading stuff on my 45 minute train, playing games, browsing web and emails for 45 minutes at lunch). how can one have consistent full bars AND a TWS so high? i'm a relative android / samsung newbie, so forgive me - but i would imagine these two statements conflict, no?

My battery life went from 12hrs to 18-23hrs, since the EC05 upgrade. Not bad. TWS is 0% for this charge.

 

[Possum15]

10 hrs and at 27% with 4%TWS. Light use day also. With 2.1 I would usually have ~50-60% about this time of the day. Don't know what I have changed.
