I'm having great battery life

Hey guys I got my EVO in the mail on Thursday, and do I love the thing! I have been reading about battery life and was a little concerned at first, but that was then. Last night I unplugged my phone at 7pm and it had a 95% charge. I played with it a bit and texted until around 12am. I did not charge it and started texting and using it for a while this morning around 10am. It is now 4pm and I have 49% battery. If this is what everyone is complaining about, im happy with it haha.

Basically, it's people leaving 4G / Wifi / Bluetooth / GPS all on at the same time that kills the battery life of the Evo. My launch-day Evo has routinely done 20+ hours of usage with no problems.
The only times I've ever seen a marked decrease in battery performance, I could find that some app was hung up in the background draining the juice.

Rooted or just stock non root?

Come back after you try using data for an extended time (texts don't need data connections most of the time), having your mail sync for even every 3 hours or so and facebook, news, weather or any other auto sync feature enabled. Watch your battery die as quick as a witch under water.

My email syncs every 10 minutes, and my weather syncs as soon as it can. (not sure how many minutes). My facebook updates pretty often. And I have news updating as well.
My phone is also NOT rooted.

I get fine battery life, with WiFi connected I get much better standby than when using mobile data. Turn mobile data off when I'm out and about and the battery basically doesn't move. But I still can get 20 hours of use if I'm not on my phone constantly. I only turn off mobile data if I think I need my phone to last more than a day. Like camping or something. I have gmail pushed and weather and all that good stuff synced every hour. Been playing with juice defender which does increase battery life pretty good but you can get the same effect by toggling your mobile data with the widget. Juice defender does turn on data every 15 mins for a minute to sync which is nice but it causes a little lag when you unlock your screen because it turns on data as soon as you unlock, a little annoying.

I highly doubt this is possible especially on the stock battey. I personally know there is no way to have all those apps syncing at those frequencies on the stock battery and still get MORE than 9 hours of use. http://forum.xda-developers.com/showthread.php?t=783364
Unless you turned off your phone somewhere in that timeline and are not telling that bit of info. With the sync frequency you just gave, I seriously doubt your battery numbers are even the correct ones you're giving.

According to that, it says your phone has been powered on for 48 minutes and used for 15 minutes. Go back and check the link I gave in my first response and look at the screenshot most people would want to see.
EDIT: Saw your edit and your phone has been in standby most of the time. I personally am not impressed by standby times. But if that's what floats your boat then so be it. I personally have gotten 10 hours of CONSTANT use on the stock battery with apps syncing every hour and get 1.5 days normal use on my extended batteries.

i was able to get 7 days battery life with minimal usage as a simple phone:

I got 9 hours out of myn and for 7 I played music, i 5 of the 7 was listening to music on my sd card. The other 2 was streaming pandora, I was proud of the evo. Lol

Where's the fun in that? Standby most of the time except for phone calls! You overpayed if all you wanted was a simple phone.

Those are reasonable numbers and I have gotten that same use out of the stock battery. This phone is a joy to play with rather than letting it sleep all the time.

my lastest its not stock but ill take it before i recharged i was 10 mins short of 20 hours

Yeah, I have gotten a whole 24 hours out of myn, but that was when it was new with little on it , and its first root and rom.

I know that people talk about losing the first 10% in like 10 minutes, but has anyone ever noticed how long it takes to lose the last 10% of the battery? That sht is frustrating, going from 90 to 70 for me takes only about an hour, but the last 10% for me can carry me another 3 hours or so. My battery is teasing me.

DK28 Battery Life ..is 13 h 28 m insane or normal?

With the newly leaked Dk28 there definitely seems some battery life improvement. I am on 13.5 hrs unplugged as of now and still about 20% battery life left.
I charged it before going to bed yesterday night... left if unplugged whole night.. moderate usage today morning.. emails, browsing, phone calls.
4G service on .. everything else off.
I dont think I saw something like this on Eclair... is 13.5 hrs normal or is it really really good??
What are you experiences? Please share.

I'm at 15 hours right now with 62% remaining, but that doesn't seem out of the ordinary for me. I went a little over 30 hours on one battery a couple days ago, which I think is pretty good considering it's a stock Froyo kernel.

I don't know what your settings are, but I can usually get about 40 hrs on one battery cycle. Most of that 40hrs is downtime, but I can manage about 3-4 hours of display time(games, surfing, etc) and about 30 minutes of talk time.
Your numbers look a lot like mine did before I started killing the DRM service.
Edit: Forgot to mention I am on 2.1 though.

That seems pretty normal. I unplug my phone when I leave for work and plug it in when I go to bed and it's usually at about 40% or so by that time.
For what it's worth, I'm not seeing any difference in my battery life since updating to 2.2. This is pretty much the same as I was getting on 2.1.
I will say that prior to DI18, I was getting about 50 hours on a charge. My last charge before DI18, I had gone almost 72 hours before plugging in to do the update. DI18 killed my battery life, and it's been about the same ever since.

I do have Autostarts killing DRM at boot. Not sure that it makes a difference on Froyo though.

I was on di18 from the day i bought my phone and i never got thru the day without plugging in at work.. i plug it in at night..pick it up100% charged while going to work and by about 2-3 with moderate usage it wud be around 25% left and definitely die if i dont charge at work on the way back home.. which is something i m not seeing now.
Are all you guys using this drmservice.. i wud like to kill it too .. not sure what it does tho.. will do a bit of reading..

I usually only have to swap batteries once a day. I leave wifi on nearly all the time. Bluetooth and gps are usually on for about an hour a day. I listen to music with the phone during work and when I go for a walk in the evenings. I play some games and browse the web here and there, too.
Last night, I swapped batteries before bed, and lost 11% in 9 hours, with wifi on. If I'm constantly doing things with my phone (gps navigation, games, etc) then I can kill it in 6 hours or so.

I'm getting round 18 hours with heavy wifi use and tons of browsing

This is right around what ACS members are seeing. I myself regularly go over a day with light to medium use.

That's normal. In the last seven hours, my battery is at 80% with live wallpaper and max brightness on.

Is this with the regular 1500mAh battery ?

For people getting 13 hrs+, or anyone really, what does your spare parts network usage look like? I'll update this post with mine.
I've been all over the place with battery drainage. (I've calibrated since new kernel). all details equal (same app setup, traveling to the same place, etc), sometimes I drain 15% per hr, sometimes 5%.
sent from my RAZR

I read some of the comments and had to go back to top to see if I was in right thread!!
My 2.1 rooted used 2% an hour, I'm a moderate user, but most usage is data on 3g. I would have 50 plus left at bedtime.
Went to DK28 - idle used 6%, had to charge my late afternoon with any usage. Same setup, actually less programs.
So I rolled back, this was the same as pre Sept 30 upgrade and yes, I was toggling, killing, stopping, everything the same.

Just this morning, I took it off charge, spent about 10 minutes going through facebook and seesmic, check the charge percentage and I was at 93%.
What the HECK are you folks doing to get 18 hours of heavy browsing on WiFi?!
I really don't want a phone that has a tough time making it past lunch with it mostly sitting inactive. Heck, my ancient G1 did much better than this. Just checking now, I unplugged it at 6:30, and I'm at 89% already. Although I will say that from about 6:30 - 7:42 I've gone down 4%, so I suppose that's not too terrible. I'd love to have 2%/hr.
Addl data:
From 7:42 - 9:34 with it just sitting on my desk, it's down to 81%, so it's still losing 4%/hr without being touched.

What kind of battery life are you seeing?

Just recently got an Incredible. Using the HTC extended battery (2150 mAh) and I'm still only seeing ~14 hours of battery life. Also currently using CM7.
What is everyone else seeing?

I'm using the Redemtion Rom 2.2 with Incredikernel 12/21, and with the stock battery I can easily get over 20+ hours out of it. I'm also always on my phone. What kernel are you running? That might be your problem.

I'm using an 1800 battery and regularly kill my battery in half that time. I'm actually happy if I get 7 hours out of it. Since you have the 2150 battery pick up a wall charger for the stock battery and carry that on you too.

I'm running SkyRaider Athena 1.2 with Lou's #9, and I get around 20 hours. Pretty standard usage, nothing crazy.

I am seeing about 18hrs.

Running seidio 3500. Moderate to very heavy use i see around 16 hours. With little use to moderate a full day and a half to two days. Running incredibly re-engineered with ziggy's 012111 bfs kernel ocing to 1.036. How you people are getting 20+ hours on the stock battery is beyond me.

I'm with you on this. Although I send around 1000 texts a day use the phone probably an hour tops and use the internet a good bit. I call this average usage some call it insane so maybe some peoples average usage is barely talking it.

Well,
I was on the stock 2.2 OTA and I was doing ok. it was better than 1.1.
However I've recently been running 2.3 (http://forum.xda-developers.com/showthread.php?t=865331) and my battery life has improved a little bit.

I'm running virtuous 3.2 and usually after a the day I usually get home with about 60% with pretty light usage.

With very light usage (listening to audible books via audible.com app for about 6-8hrs, 5-10mins of phone calls, limited internet) with the 2150 battery and Lou's #4 kernel I got 52hrs from charger to 14%. That is definitely not the norm, but I thought it was pretty cool =p.
Normal moderate to heavy usage I get 24ish hours from charger to 10-15%.

Na up where I live everyone gets the $5 or $10 Verizon o ly prepaid texting plan. So that's the only way we talk.

Uh 1000 texts a day. Lets say you get 5 hours of sleep. That's 19 waking hours. Thats like one text message sent every minute for 19 hours. Not to mention received. i hope you're exaggerating hahah
I use mine kind of heavily with texting maybe a couple hundred total per day. 2-3 hours screen on total, maybe 15 minutes of talk time. I get 19 hours according to Battery Left. Running CM7

I'm averaging. Quite honestly there are many times where I don't get a break to actually put my phone down for like an hour or so at a time. But I judge the thousand a day based on me resetting my handcent set counter and two weeks later iI was at just over 15000 sent.

Sure, I am playing around with CM 7 nightlies at the moment, but I'll switch back to my old set up and see if I cant get a ss of a number close to that for you.
As I said though, it was very light usage for a few days.

I was running CM6 with invisiblek #18 and getting over 18 hours on the stock battery with pretty consistent use

Using SR 3.5 rom and chad's latest incredikernel.
With mostly having the screen off (no more than 45 min on) it lasted 48+ hours with 22% to spare - note that is not my normal usage, just a test.
Normal usage for me is:
Solid 5-6+ hours of screen on, and it'll last a good 23 hours (as of last night, long day lol) -- Most of the time after a full day I'll plug it in with 40%+ left.
Daily usage also includes
- 45mins of GPS usage
- 2-4 hours of Pandora streaming
- ~50 txts
- ~20 minutes of phone calls
- Youtube for ~45 mins
- E-mail / web ~ an hour
- 20 minute of games
I practically live on my phone but usually make it to the end of the day with 40+% left, depending on the day may be less- but I've never gotten the notification since the Kernel and ROM change.
Overclocking above the standard 998 will drain your battery pretty quickly, more than most other things you're doing. I noticed this and also noticed that overclocking didn't do much for me because 998 was smooth for every game I was playing.
Using HTC extended battery also and I do not bump charge, see:
http://forum.xda-developers.com/showthread.php?t=871051

I just find that hard to believe. If i stream pandora for an hour with a full charge it will drain my battery down about 20% thats using lou's #8 kernel and his redemption 2.3 rom. Thats with a 3500 seidio battery after a wall charge not a plugged in charge.
Not doubting you one bit but damn thats alot of tasking on a stock extended battery too end the day with 40% left.

Suggested setup for amazing battery life

hi guys/girls,
i wasn't able to find any sort of thread pertaining to what setup everyone is running for the best/worst battery longevity so i figured i'd at least post up how i have my phone setup in order to pull off a full workday/night and about lunch/dinner time til i have to absolutely recharge my phone (30-35hrs max). maybe if it helps someone get the most out of there battery between charges then great. so here we go...
how i use phone:5-10 incoming emails daily (hotmail/aol)
200ish texts/day (incoming/outgoing combined)
1-2 hrs or so internet browsing/zooming in out
1 hour talktime daily
listen to 3-4 hrs of music on sd card at work
signal strength 3-6 bars at all times
what i have running/not running:
gps off
wifi off
network on
1 min backlight on
full animation on
auto brightness on
vibrate/sound on for calls and notifications on
volumes for sounds set to 3/4 or so
no task killer installed
facebook/friend stream off
weather sync on
google sync on
news sync off
stocks sync off
foursquare on
i personally charge off a usb off of my computer when phone hits about 5% or so. so maybe that is charging it slower and not wearing out the battery cell? i've read that the slower the charge on a battery the better, correct me if i'm wrong. my phone has had no adverse effects and has not bogged down once. i hope maybe this will help in some way to narrow down what may be causing some users phones to die faster.
maybe have others post their setups to see a trend would that help?

I pretty much have gps, wifi/4g always on if I'm at school or home, and auto sync and I get 10-14 hrs. Yesterday I went from 8am to 1am and battery was around 55 percent but I didn't use my phone like I usually do. Regular usage usually nets me about 10% an hour.
Each day I probably send around 200 texts, read forums, google reader, and pulse in total of about 3 hours and play about an hour or two of games.
I use to use juice defender app but I did some testing over a week and it doesn't help at all imo.

most battery monitors or battery saving apps actually have the opposite effect, especially the battery monitors. They're using power to monitor the battery condition, so they tend to do more harm than good.

Yea o was using a battery widget for a week or so and it seemed like it used more battery than it was worth. I try to run my phones as lean as possible and only use what I need when I need it.

As far as I'm concerned thats borderline amazing. How in the h-e-double hockey sticks are you guys getting such great battery life? My phone doesnt hit that and all I really do is IM and browse the web maybe a combined total of 5 hours a day and thats pushing it.

01/27 update...another update if anyone is keeping track...pulled phone off charger at 8am now its 11:30p (16 hrs+/-)..45-50% battery left...also realized i left gps on with navigation running for 2 hrs from lunch earlier in the evening and prolly sent out 50 texts in last few hrs since last battery status update and looked at pics with a co-worker...so yea so far the setup above is bringing some good results for me.
01/28 update...its 2pm (30 hrs later), and phone just beeped at 15% battery left. finally ut it back on charger so i have a full battery for work. so there you have it folks. pretty nice battery life if you ask me...been texting and calling for the last 2-3 hrs today too which triggered the battery beep.

try recalibrating the battery...basically let it die all the way to the point where it wont even turn on anymore...then I like to remove the battery for like 30 secs or so but im not sure if its actually necessary...then plug it back in and let it charge all the way til the led turns green...then take it off the charger and turn it on....did that and i noticed a big difference especially after a day or two

Your battery life so far?

At the moment it seems like I'm getting around 5 minutes per percent (around 8 hours of constant use). The weird thing is that seems to be the case across all use, I get the same results from web browsing as I do reading comics in airplane mode.

I get pretty incredible standby though with set cpu. I'll go to work and come back after eight hours or more with one or two percent gone.

Yeah the standby life is amazing
Sent from my Samsung Fascinate via Tapatalk

set cpu app helped me get amazing stand by times. i mean i lose 1% every 24 hours propably.
during normal use, i get average 4-6 hours. surfing youtube, downloading, playing games. usually 5 is about right. People who say they get 8-10 hours heavy use are on one.

I would agree with 4-6 hours with constant use such as reading or twitter browsing. I previously had a Nook Color with CM7 on it and got about the same. Standby is amazing I almost never turn it off.

After about an hour of surfing or playing a game I lose about 20% so about 5 hours. But when watching videos I get around 7 or 8 hours

This sounds awesome I just got 48 hrs on included 4--5 hrs of use. Down to 2% ... wifi is set to go off with screen (after 1 min) not. Sure wat else to change

Hmmm. I was hoping that rooting/SetCPU/screen settings could get me closer to 8 hours of life, but that's not the case. I'll probably just sell the Iconia since the battery life is my main reason for owning a tablet, and in this case it isn't that much better than my laptop.

Run time.
52 hrs. %79 & moderate use. Never shut it off & still testing. Want to see how long it can go until I reach %30.

not trying to be an ass, but what are you guys using your tabs for? i run taboonay rom with thor kernel and good to very good battery life. I use my tablet all day long at work for e-mails, pdf viewing, gaming when i shouldn't be, and playing around on the internet. I wake up at 5 am everyday unplug my tab and start the day. With said usage i can go from 6ish AM till almost midnight and still have 20-30 something percent battery left. I wouldn't say i use it hard core, but i put it work. Just charge it while your asleep and it should last all day. Now on the occasion i watch movies on it it does drain the battery like a bastard but i can still get 5-7 hours of non stop movie watching on it. I really can't complain about the iconias battery at all. If you expect this thing to run like Carl Louis all day long without plugging it in you're in lala land. Theres alot of threads on how to get rid of cell usage drain, and look at whats killing your battery it may be an app or something you did settings wise to drain it faster.

Completely agree, I got mine on Saturday and apart from the initial charge it's only been plugged in twice. Used on and off throughout the day on Sunday, most of Monday evening, all Tuesday evening and all Wednesday evening, playing games and on the web with a bit of youtube and playing around. First time charged at 35% on Monday evening, second time yesterday at about 11pm as it was down to 10%. I think that's pretty damn good myself. It's on OTA 3.1 and Rooted
As for comparing to netbooks, have a look at the size of the battery in a Netbook compared to the Iconia. Of course they're going to last similar amounts of time - The Iconia has a smaller battery but has less to power versus the netbooks larger battery with more devices to power.

I'm at 67% after about 27 hours with about 2 hours of actual use. I guess that's ok. I flashed the Minimalist rom on Tuesday so I probably haven't given the battery enough time to break in. Sorry for being a *****, I'm just impatient >.<
I was kind of afraid if it would last me through a day of classes when college starts back, but I think I'll be ok.

I was getting around 5 days total with 1 to 2 hours display usage before the update to 3.1. Now it only goes 2 days when on standby with less than an hour of usage. Going to download SetCPU and try that. I have not changed anything (widgets) since before the update, so I have no idea what's eating up the battery.

Does anyone use there tablet in this post?Lol
I use my tab all-day long and I usually have 20% by the end of the day.

I use my tablet about 4 hours a day
I have to charge every 2 days
I charge during 2H30 arround.

Mine has been doing pretty well lately. I guess flashing roms took its toll

setcpu settings?
I'm using SetCPU as well, but getting no where near what you say. I left it on sleep last night and it drained 15% - same as before.
But, maybe I'm not using it right. I enabled the "screen off" profile and dropped the speed.
What are you doing/setting to get that standby time?

set cpu app helped me get amazing stand by times. i mean i lose 1% every 24 hours propably.
during normal use, i get average 4-6 hours. surfing youtube, downloading, playing games. usually 5 is about right. People who say they get 8-10 hours heavy use are on one.

Ok, I activated a couple more profiles including "time", temp, low battery. Low battery definitely turned on and I saw the change in the icon on the bottom right. I think the "screen off" is not turning on - basically can't see it when the screen is really off . But, it's definitely draining the same amount of battery.
Am I doing something wrong?

SetCPU didn't help mine either. Tried a few different profiles. I thought the one that would help the most is Screen Off, I set it max and min to 216mhz. No difference in battery drain overnight.
