Evo Battery Life: Massive Improvements

Man, things are going well now.

No task killers or other mem managers.
got 16 hours of moderate (normal) usage out of it until i finally got down to ~10% at 4pm.
popped in a new battery at 4pm and have dropped to 94% in the last 2.5 hours.
just fantastic, at least, compared to where I started with this thing a month ago.
hope everyone is having similar results.

I'm having better results running stock..

i was getting 7 hours, at most, doing the same thing i'm doing now on stock. glad your's is working out better.
do you only use your phone to make and receive calls?

battery life
somone post a damn link to a video of the process u guys are using to get good battery life

The process is to get rid of whatever is using your cpu cycles while your phone is inactive.

Yeh damage control I now get 22 hours if awake time
B efore id get 18 hours of uptime.
Dc is the best I have tested then all. I get 34 wakeups in powertop. Do that test on any other rom you ll get 2 to 3 times that

I clocked 32 hours with moderate use. And I am using an app killer... but I just watched for apps that were CPU hogs and found replacements for them. There aren't too many that affect it so much to trade them out, but you might be surprised by your findings

No way I'm beating thee crap out of it. Dc limits higher cpu speeds with dconfig so if you have that option checked its slower but who cares I don't notice it saves batery like crazy. I'm on speaker phone conference calls all day. Bluetooth/gps on. Exchange sync as items arrive. Its crazy good I'm using syspannel monitoring ilk posy screenshoys, tomorrow.
L I ikesais, powertop gives me 30-40 wakeups. Some roms,are in the hundreds or thousands, but the proof will be the screenshoys tomortow, or try it yourself

haha, great name for it. i'm having better results too doing the charging circle jerk. 20+ hours with moderate to heavy usage

My battery life has been great since the 1.4x update... As an FYI the facebook syncing from 1.3x caused SERIOUS battery drain if you had it linked to a facebook account and had the HTC people widget on your home screen. I used 2 gigs a week while having the phone on wifi at home most of the time due to this bug!

So, at what point do I just throw in the towel and ask for a replacement battery from Sprint?
I've done the "battery circle jerk" twice, now, with no improvement. In fact, this morning, after completing my third jerk (battery jerk - get your minds out of the gutter), my battery percentage fell to 95% after 10 minutes of almost no use. Either this battery is bad, or the EVO has some serious issues with topping-off a charge.

^I have the same problem.

Losing thee first ten percent q quickly is very normal with this phone.once it his 85% it'll start to even out. Personally I've notice charging with the wall charger seems trio make this problem a little better

Sorry, I cannot do screenshot 'cos my phone is not rooted and complete stock everything, but as I posted in some other battery related thread my phone hold to 2 days 12 hours and 30 min with 3% left over Columbus day weekend.
BTW, TWS was over 50%

battery meter is in blue minimalist theme and not photo shopped i have posted other screen shots with 45 hours and so on. stud muffler if you cant go download shoot me to provide screen shots i dont believe you are getting that battery life especially because the sprint apps use the most juice and the galaxy rom is way more conservative scaling on the cpu. also no one else on stock is making the same claim as you are with that usage dont make claims you are not able to back up with proof this is android not apple. everything can be verified very easily. you do not need root for shoot me. if im not at my house where i have wifi my battery gets drained really fast on 3g with no data usage kinda sucks.

I see that the Display is at 11%. What kind of usage is this? The math says that is about 4.5 hours of being "on". I can see with the right setup those sorts of numbers being attainable. The difference being actually using the device a lot would kill more battery. What exactly is your usage pattern?
Edit: Whoops I didn't read all the way. Wifi is a big plus for battery life. I'm tempted to try out the Galaxy rom now.

so whats the point of this thread? I can do this too at my house, just hook up to wifi and the battery lasts forever, its the 3g that drains it as you said.

That's pretty amazing...I'm wondering what the 1 battery is? Car battery perhaps? LOL
I think the most I ever got with light/almost no use was around 19 hours with about 10-13% remaining battery. That's just a guess though...I wasn't trying to test the battery...just didn't talk to anyone for a day or use the phone for anything in general.

Somethings not right. Since when does the screen eat up less than any other process? Thats the top drain on all other epics

If you seldom use the phone for anything, the proportion of power used by the screen goes down, and so does total battery drain. Then you can brag that you got 60 + hours.

He still had about 4.5 hours of screen on time which is pretty damn good if you ask me. In my daily use I get around 13 hours of battery with a screen on time of about 2 hours, if I'm reading a book using kindle I get 9 or 10 hours with about 3 hours of screen on time.....so he has a higher screen on time than me and still gets like 2x more battery than me (I've seen his other screenshots) on average

i also don't know where people are getting 4.5 hours of screen on time from the screenshot. It's not 11% of the total battery time on. It's 11% of the batteries overall use. It doesn't really have anything to do with the total time unplugged. Some fuzzy math going on heh.

I was at 42% battery when I just plugged in my phone tonight so it's charged up for work tomorrow.
It's not that hard to get these kind of numbers with light use.

@styckx:
How come yours saya "Unplugged for" instead of "Since unplugged"? Not saying its fake or anything, just never seen that before lol
Sent from my Epic 4G using XDA app.

Because in the SS it's charging and changes to "unplugged for". It saves the amount of time it was last unplugged for. If I unplugged it then it will say "Since unplugged" and reset the timer.
Yeah, not shopped, I'm not looking to score e-cred over cell phone screenshots.

I use my device so much my display & voice calls generally wear down battery in 6 hrs tops. used to be 10-12 but since di18 it sucks .. might be both updates idk. I'm anticipating some good reads to learn up on flashing & such so maybe ill be able 2 get better life. my browser speeds suck

Looks like a Day or Two of Airplane mode,
Im rooted and tweaked and get about 20 good hours of use-able time

I never understand y ppl brag about standby battery life. not saying op is showing stats based on that but to me its a pointless test when ppl do it that way.

Not impressed.

[Q] Absolute Best battery?

What rom (stock sense look) has the best battery overall. I rooted my moms evo to get her a great battery life but it still seems to be dying really quickly. I am using 4.3.1 kernel. She's only getting around 6-10 hours of battery before she has to charge it. I had the evo before and could get a full day and a half before charging it. I can't remember my setup since I switched to the evo shift. Any suggestions would be greatly appreciated, thanks.

im using the cm7 rc 2 whatever kernal is package there is PHENOMINAL im at 60% @ about 12hr..... Moderate use between wifi and 3g
Sent from my PC36100 using XDA Premium App

That's the best you're gonna get with NORMAL usage and a REGULAR battery. All those users that say they get like a day or two are full of it. They get that long because their phones are sleeping most the time. I've used EVERY rom/kernel combo out there and the best I ever got was about 15 hours. I literally use my phone all day while at work from browsing, texting, calls, facebook ,twitter, and games. There should be a definition for moderate. I consider myself a heavy user; unplug at 7am and my phone last until about 6pm with about 20% left. Its not going get any better than that for a moderate to heavy user. From sense to aosp with the stock battery I just never achieved better results but I'm pretty happy since I get to work at 8am and get off at 5, buy 7pm its nearly dead and I just plug it up. You should invest in an extended battery imo.

I agree to a point. I mean, it all depends on usage. I can believe someone with light-moderate use can easily get a full day with the right setup. I do it now with CM/Savage, but I'm definitely not a heavy user.
I do see some people make wild claims of 2-4 days without a charge.. and I think it's possible IF you don't use your phone or you turn everything that makes it a smartphone off. Which is pointless IMO.
Nobody can really give you the perfect setup because every EVO seems to behave differently. We can only make suggestions. Make sure your mom s awareof all the things that can drain battery (push notification, updating widgets, weather updates etc etc). I would then research a good sense rom/kernel because CM7 is a definite WIP with different issues for different users, it may turn her off.
Maybe check out MikFroyo or Myns rom. I hear a lot about how good they are.

+1, its just crazy I see people throwing crazy hours out there lol. I think if your phone is sleeping 75% if the time then you shouldn't even talk about your results since that doesn't fit into the norm for usage. Most people check their phone like every 10 mins(don't quote me) I know I do lol. People throw around like 36 hours and even longer its insane to me.

Sent from my PC36100 using XDA Premium App

I don't know about not being able to get more than a day of battery life and use your phone. Using MIUI with a Savaged-Zen kernel I was able to go almost 2 days without even plugging it in once (I'm specifying this, because I've seen screenshots where people claim crazy battery life, but the graph clearly shows that the phone was plugged in and charging several times throughout that time period), and my display usage was still 44% of my battery. That was still minimal usage for me. I posted the screenshot in the MIUI thread if you care enough to check.
I do mostly agree, though. Most people posting outrageous battery life have display percentages around 5-10%, clearly never removing the phone from their pockets.
Anyway, as for the OP, the biggest missing variable is that we don't know at what percent your mom considers it necessary to charge her phone. If she plugs it in around 50% to be sure she can make it through the day, that means she could have gotten another 5-8 hours of battery life (assuming she's not draining it down to 0%). This fact could make the difference between bad battery life and a paranoid mother.

Try the ava froyo z3 I love it best rom I've used so far so guess I'm sticking with it o and get her juice defender with ultimate juice and lock it down so it kills anything she's not using

I agree with most of you people. Initially went to FreshEvo by Flipz when I rooted and battery life did not change much from when I was running stock. I have since switched to CM7 and battery life is significantly improved. Now getting 12 hours on a single charge with moderate use. I always turn 4G and wifi antenna off when not performing any data-intensive use. But I refuse to kill my 3G data connection when my phone is in my bag or desk while at work. Reality is that it IS a smart phone and killing the data to save battery life defeats the smart phone bit, no email no Facebook syncing no MMS etc. The only time I kill 3G is when I am in the mountains skiing.
My problem is that I work a 12 hour shift so 12 hours of bat life is not ideal. I have invested in an extra charger but would obviously be happy to not use this. I have heard lots of testimony that the savaged Zen kernals show some promise in improving bat life. When CM7 final drops I plan on flashing one of these kernals with the new ROM on wipe. I will stay away from the SBC version though for fear of improving battery charging but having my phone melt down or pop on the night stand next to me while I sleep... or worse in my pocket!
I will report back if I get any significant results.

CM battery use

On stock my battery use would indicate display as the most used item under battery use.
On CM, however, cell standby and cell idle I think takes up 43 and 40 percent respectively while display only takes up 5 percent... is this normal? I thought on a highly efficient system, display would usually be the most taxing power draw item.
Any input would be greatly appreciated.
P.s. big ups to toast and the CM team for making it happen!

Similar situation here, though mine shows display at 15%. I seem to have similar overall battery life as I did on stock though.

For the most part, unless you never turn your screen on, display should be number one
Sent from my PG06100 using XDA App

I see the same thing as the OP, however I find that my battery life is improved in CM7. I am running Nightly 35 right now, but it was pretty much the same in RC4.1 as well.

Still testing but looks the same... phone idle and cell signal take up the most but display is now 10%.
On stock I got 48 hours off a charge if I stuck to wifi places. It would be 24 hours in and id have something like 56percent left.
On cm I'm 8 hours into this experiment and have 44 percent left.

I've also noticed my battery life isnt near as much as it was with a Sense rom. I looked today after reading this post and realised it said I was 59% time without signal when I havnt dropped service once. I wonder why that is... Hopefully they get this figured out as I really liked how CM6 gave my Hero more battery life over stock not the opposite.

My cell standby is right at the top with 37% but my time without a signal is 0%

Ok day two of testing coming to an end... I tried the suggestion of turning on airplane mode this morning then off to see if it made a difference.
Off the charger at 8am
At 15% 10:28 pm
Cell stand by 32%
Phone idle 25%
Wifi fall in the middle here somewhere
Display 5%
Still not the kind of batterylife I got on stock. I just goto school and home these days pretty much same routine everyday and constantly on wifi.
I'm gonna try to set the clockspeed down from default of 1ghz in cm to 800 to mimick stock tomorrow and see if that makes a difference. Then maybe try a new kernal like x99 later on in the week.
Will report back!

I'm getting better battery life, by quite a bit. But I just noticed I've been running at 800MHz under the "conservative" governor, so that explains part of it

how's the responsiveness on the conservative govener? Any lockscreen lags or anything?

I haven't noticed much lag if any. Except occasionally when opening some apps, not enough that it ever really bothers me.
I switched it to run at 1209 MHz, and I can just about watch the battery percentage drop, so there's a definite difference there

The idle time on Unity is very good. I'm somewhere around day 2-3/4and just now getting to 50%
However when you're using it the battery tends to die pretty quick.

Pyromod! its amazing, I get about two days battery life.
I never worry anymore, If i'm going out of the house around 5 PM with 20 percent battery life, I'm good for the rest of the night and morning.

As is true with ANY rom you use lol.

Right now I'm using cm 7 and when its charged to 100 it stays in 100 for a long time than it drains pretty quick

That's how it is. The firmware interacts with the battery in a way that any % over 90% is considered a full charge, so sometimes this comes away with the phone sitting at 100% for a long time (up to like 2 hours for me if I don't use the phone much), then draining normally. It doesn't drain fast, it just drains fast compared to the battery sitting at 100%.

Not true. CM6 had a drain rate of 3%/h on idle with no connections and me popping it on once or twice an hour to get a text.
Cm7 was around the same. All stock clock with downclock with the screen off to around 500mhz.
Unity's idle rate is only about 1%/3-4 hours. It's insane.

No, I mean you clearly are going to drain fast when using a phone compared to idle.
And any ROM with a proper kernel can be undervolted / underclocked with apps to disable data in order to drain less battery in idle.

OMG I just flashed cm7 a while ago and the battery life is amazing!!!!!
I'm on xda for about five minutes and it hasn't changed from 100
Amazing!!!

I can't tell if you're kidding or not, but the phones and ROMs I've seen all exhibit this behaviour. The OS will report the battery at 100% for a long time, as if the battery has more capacity than the OS knows about. A more accurate estimate would be to wait until you're at 99%, and then see how fast the meter drops. Better yet would be to use something like Current Widget or Battery Monitor Widget to record real-time current draw, then calculate how much energy has been consumed.
I wish there was a way to calibrate what "100%" actually means, but I don't think that is possible, since it is a hardware limitation.
