The longest anyone has had it on their phones is like 15 hours. Give it a few days.

You won't be able to really tell for a few days when people stop picking up their phones every 10 seconds to play with it.

I fixed my gps early this morning and then set it up with a full charge to do a battery calibration. I turned 4G on to help it drain. I also used it to read xda for about 30 minutes earlier this morning (not sure why the battery stats don't seem to show everything that has been running). Here's where I'm at 8 hours later. I would say the battery life is pretty freaking great! Can't wait for some UV'ing once we get source.
Note: I have Overclock widget set to 1000/200 screen on and 400/200 screen off.

i somewhat second this i have left it unplugged all last night and i am at like 80-90 percent full with some what use..

I am still using juice defender, but my phone as been off the charger for almost 12 hours and I am probably around 75% battery left. I will be testing out turning off JuiceDefender tomorrow, but for now it looks amazing.

CRAPPPP
it some actually deads faster than 2.1

I've been having pretty fantastic battery life. So far the phone has been unplugged for 6 hours, I've been texting on and off all day, and played angry birds for about an hour. I'm sitting at 75%. Probably not fantastic but not bad.

I've noticed an improvement, but as to how much, I'm not sure. Maybe 20 to 40 percent better.

Quote of the day!
from a epic Galaxy far, far away.

excellent battery life
61 percent with some youtube , texting surfing the web angry birds and 4g on(sleep mode for 4g works really well) and apperently my gps was on all day. Its been 7 hours and 32 minutes ..I would normally be at like 35 percent

I have definitely noticed an improvement. It seems as good as baked ultimate and that says a lot.

I am getting battery life like it's a completely different phone.
I was always rooted but with stock roms and kernels and on 2.1 my battery life was frighteningly bad. I have been on for well over 8 hours and using my phone off and on all day checking out froyo features and the battery indicator is showing still nearly full battery life. On 2.1 I would have had to pop it on the charger at around 2 pm today or earlier.
* I am going to be making a thread about LEGIT improvements that froyo gives us with this phone. There are a ton of piss and moan threads, but froyo adds a ton of features (several i'm sure I don't know about) and MUCH BETTER battery life. *

[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

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.

I've always wanted an extended battery but I keep my phone in my pocket; are they super bulky? I really want 1
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 have the Sprint 2600 extended battery and it isn't as bulky as you would think. I actually think it is less bulky than my 1500 with a case on it. I don't notice it at all and I carry it in my front jeans pocket.

Also display did not use 44 pct of your battery. It was responsible for 44 pct of your battery drain. Big diff.

Sent from my PC36100 using XDA Premium App

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.

Battery Tips?

I just want to know what I can do to improve my battery on CM7 nightly 32. I'm at 21 hours now and almost dead. Yet I see people get stuff like 2 days and 10 hours... I have tasker and the only profile I have is when the screen goes off it turns mobile data off (not sure If it works so I also use apndroid). I NEVER use wifi, bluetooth, or high brightness. I do however have gps on so in case I lose my phone is lost or stolen I can track it. So there's no way I'm disabling that. I have tried juice defender but figured since it can't effectively disable data for 2.3.3 I saw no point in the app. Any tips?

21 hours on moderate use is great battery life. 12 hours is usually the measuring stick for smartphones, less is bad, greater is good.
Don't know who you saw getting two days plus, but they are either not touching their phone or have an extended battery.
Sent from my T-Mobile G2

Best way to extend battery life is to get an extended or high capacity battery. I just got the Mugen Power pack, not the chunky one, and im in the process of breaking it in.
On my stock battery i was getting about 17hrs of moderate use. Almost no talk but alot of texting, engadget and youtube mostly on wifi with gps always on. That might give you an idea, plus, there are countless battery related threads on here.
Will post back in afew days after my Mugen has cycled afew times.

I have 4 stock replacement batterys and never plug my phone in to the charger. When my phone is at about 5% i just take one out and pop the next one in and charge them in the wall... I know its not the answer you want but I never have a problem with battery life lol

I would agree that 21 hours is great battery life on this phone. I can get a week of battery life on my phone if I put it in airplane mode and stick it in my desk drawer =P
Not sure how big of an impact the tasker profile has. Unless your screen is off for long periods of time I would think that it might harm the battery life because every time you touch the device, it has to 'search' and connect to the tower again.
You can try running the phone at the stock CPU speed to see if that has an improvement on your battery life. I currently run the same 1017/245 as you with a screen off profile set at 245/245.
For me, as long as I can make it through a day's use, the battery life is fine. With moderate use I can go about 15-18 hours and heavy use I'm at around 12. The car charger in those cases is a life saver.
Bottom line is, battery life really depends on your usage habits. Those people getting days out of their phones likely aren't using them very much...

well i have setcpu set at 806 max and 245 min. screen off is at 245/245 and on powersave governor. other then that its on ondemand. i also have profile set to reduce the CPU based on battery. I have it set to <101% its at 806/245 , <41% its at 768/245 and less then 25 is 368/245. i realize that these are low speed but i hardly ever get lag and i use it for everything, music, video, youtube, internet, twitter, facebook, xda , and a here and there gmail. i guess if im getting exceptional battery life... anyone want some tips?

I find the more variation I put into profiles on setcpu, the worse my battery life gets. Theory - it is constantly watching and making changes based on your CPU needs and battery. So I have mine set to 1113-1113 performance, 245-245 powersave screen off, 245-245 powersave 45degrees+ and for your mobile data, try just having a widget to turn it on and off as you need it. You probably don't need it on everytime you turn on your screen do you?

The apndroid widget eventually gets out of sync with on/off with the data... I think its gingerbread. Most apps can't effectively turn the radio off. I hope they make one soon!

I find the stock battery to be not that great. I bought the Chichi batteries way back in October (when they were still considered cheap) and theyve been great. I havent really done any new tests since October, but back then (before I had a data plan) I was getting atleast a day and more (from 100% to dead) with moderate usage.
I'd look for a high capacity battery, though they seem to be expensive now.

Ill post a battery success story...sounds nerdy lol. And i live at my own home with my own family lol.
My mothers g2 is rooted and running cm7 nightly 29 or 30, I installed it last week. I asked her today for the first time how the battery was after a week. She is using an aftermarket 1800mah battery, wifi only at home, she was almost at 32 hours and had 39% battery left!!!!
Not sure of all settings but i put it on 1113mhz, on demand with min 368, autobacklight, wifi only at home, bluetooth is always connected and on. Talk is about 70% of her usage overall. 4 gmail accounts. I did not install set cpu at all. I even stopped it on my phone because it didnt help me one bit.
Not too shabby. I was at 57% with some texting but a lot of gps usage for latitude and wifi always on even when not at home.
sent from the rooty tooty fresh and fruity cm7 nighly powered G2

here is what i get out of a day (battery consumption for specific tasks are mentioned in percentages measured using juiceplotter)
wifi on constantly
display set to 24% brightness
background sync enabled (google, weather 6hrs, whatsapp and facebook once a day)
45 min video (rockplayer no h/w decoding) 15%
1 hr browsing+chat 15%
30 min calls 6%
20 min music+chat 5%
20 min general usage 5%
1 hr flash streaming 15%
24 hrs standby 24% (@ 1% for every hr of standby)
15% battery remaining after 24 hrs i.e. low battery warning.
i disabled the use wireless network option under locations and always on mobile data
and get much better battery life, also i use wifi constantly when available (which is 90% of the time), it is much better for battery life than using 3g or gprs/edge.
pretty amazing battery life IMO i am very happy.

So i have cycled my Mugen 1800mA battery acouple times. on average, i'm able to get about 27hrs of heavy use. Here are some settings as a baseline:
Always on Data
Wifi always on
Auto brightness
1GHz clock speed
massive amounts of text use
massive amounts of screen on time
will report back in afew days time after some more cycles.

oh okay thanks, where could i buy a decent battery, adding no bulk but not too expensive?

I'm wondering the same thing... the Desire Z only comes with a 1300mAh battery... My previous phone had a more powerfull battery (2100mAh) and that was an older model WM6 smartphone (which was rubbish on power savings) and it would outlast the desire Z... Even after two years of extensive use, the old phone's battery is better then this phones brand new battery
I've been unable to find any official HTC batteries for the Desire Z which pack more juice...

At the OP. What is your signal strength like? Mine is rubbish at work as I work in a converted barn and that makes a big difference to the battery life.

I am in the process of 'breaking in' a new 1800 MuganPower battery. Fits perfectly with no mods needed.
It should take a few more charges etc to settle down, so things should theoretically improve.
I pulled the plug off charge 6.5 hours ago.
I have it set to use wifi when at home, and 3g for the phone connection (I have a 3G femtocell at home).
When I leave my home area, it switches off 3g and wifi and drops to 2g.
I have made a couple of 2 minute calls, checked my emails and twitter, and was out of the house for say 1.5 hours earlier.
I have had a couple of texts to which i replied.
I am on 95% charge now, and pretty pleased with that.

I've got the same mugen battery, and get through a full day easily no matter what I do. Screen full bright, wifi always on, some internet, games, gps.... etc. Only 7 hours of battery to me sounds terrible.

since my last post, i havent touched the phone at all, and its got 66% charge -__- i seriously need a better battery, may buy the mugen, would you say they are worth it?

What percentage per section(standby, display) is being used?
Sent from my 'SilverBullet' HTCDesireZ running CM7

mobile standby 33%
wifi 28%
phone idle 28%
display 5%
im surprised its been 10h 15m and im still on 58%
the battery seems okay when not touching the phone, as i have only checked facebook for 2 minutes, and sent around 10 texts (been playing football)
looks like imma turn off wifi when not using it from now!

When I first got my Desire Z when it first came out I was pretty disappointed in the battery life. I tried programs like juice defender and minimized every possible battery sucking option I could find. I could maybe get 12 hours of use out of it so I bought a 1800mAh MuganPower battery which gave me maybe 15 hours instead. Pretty poor I thought but what more could I do?
A couple of months ago I finally did a factory reset after encountering a lot of frustrating little bugs, some of which had been around since the phone was new. Since then not only has my phone worked a lot better and faster, but battery life is MUCH improved. My phone now consistently lasts 24 - 30 hours with the same usage or more than I was using it before. So obviously buggy software can make a huge impact on battery life and it's not something you are going to be able to easily discern as to what program(s) are causing the problem.

Hmmm im not sure then..
Sent from my HTC Vision using XDA App

Okay, played a bit of speedx 3D, heavy texting and facebook/gochat, still on 31%. Battery seems ok, still going to invest in a better one though, as using the phone for games or internet heavily drains the battery, whereas standby seems to be quite good, but need to turn off wifi. I will see how it fairs tomorrow, and post a picture.

Use coredroid 1.0 it has fantastic battery life. Its a sense Rom but it has the best battery life I've used on any Rom.

Battery life today was average. I got about 9 hours out of it. I had left wifi on though will test again tomorrow.

my battery conservation method is simple:
- Turn on wifi and leave it on
- Set the phone to GSM only.
This almost doubled my battery life using stock HTC gingerbread.

Why would turning on wifi improve battery life?

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.
