first off, i love this phone. no joke, but the battery is well...laughable to say the least. on my HD2 running android, i get double the battery life and they HD2's battery is a 1200 battery, the EVO'S is a 1500. and android boots off the SD CARD and has NO POWER MANAGEMENT on HD2'S. my evo dropped to 54 percent battery today in 3.5 hours. no wifi, no bluetooth, no GPS and no 4G...all im saying is... WHAT THE ****!
It gets better. Load up some custom kernals + setcpu and you'll get great life. I'm running CM6 + snap 8.2 and it lasts the whole day with moderate use.

There is plenty of info on battery issues with EVO.
First... I would recommend rooting.
Second, use the FRESH build based off the new OTA leak.
Finally, change Settings / Mobile Networks / [uncheck] Enable Always-on
Then... ALWAYS keep your WiFi radio on. Add your home network if you have one... and wherever you go, add whatever hotspots you are in proximity of.
And if you ever consider doing a new build, backup your WiFi access point data via Titanium Backup before you do.
That should just about cover it... You will get a full day of use PLUS some out of that battery.

i rooted my phone within 2 hours of purchasing it...i will look into what you mentioned later. im gonna condition my battery for the 4th time in 5 days..
PS those 3500mah batteries on ebay for 10$ and the same 2000mah batteries.
If you get one, get a seido. I just bought 2x1500mah batteries from tuttoit, great backup batteries... charger too 9.96$ shipped.
Oh and I am getting great battery life with snap and cyanogen's rom.
yeah i am going to look into all the batteries, and i love sense, that is why im not on CM6. all my other phones are running it (G1, MT3G HD2). now that i have a phone that runs sense naturally, i dont wanna change it. i love sense! and this thread was just a way for me to vent about my crappy battery.... lol

When you rooted it, did you also flash the newest radios? Trust me on the fresh build.. it rocks... but also, most importantly, use WiFi whenever possible... and turn off "always update"... those are all the most important.

No when I got my evo I was clearly.told and shown a doc from sprint (the manager over mobile area is a buddy) to tell everyone to expect 6 hours of battery life with normal use. I was able to squeeze out 8 - 9 myself. I know people say conditioning the battery is a waste of time . IMHO do it I noticed a nice increase in battery life. I have to laugh at people who get pissy about battery life when they are holding a mini PC.
Myself i avg. 18-20 hours a charge with normal use. I have 2 backup batteries so I don't worry to much about juice
from the fade
I really dont feel the Evo is a bad phone h, hell I love the damn thing . I just feel HTC kinda screwed up things in the process . One telling customers to expect 6 hours of use is alittle of a joke . Who the hell only works six hours a day ? Or is that six hours also include you getting up getting ready for work then coming home before you go to bed ? Second , its pretty clear the Evo has a bug in its charging system . People have reported that using stand alone wall chargers to charge the batteries they are getting improved life out of the batteries (Sorry I have never removed a battery from any cellphone I have had in the past to charge it and not gonna start now) . Third yes the HTC Evo is litterally a pocket pc with capabilities most phones dream of having . Then why the hell did they give it a 1500mah battery ? Thats like strapping a 55 gallon drum of fuel to the space shuttle and saying "Yeah this outta make it" . Sorry for my rant had to get it out (plugs phone in to charge again) LOL
OP, I like you, you're funny
A couple things..
1) Why do you have your CPU governed below 700mHz while awake??? You won't save battery that way, your phone runs at a gHz, use it!!
2) Setting your min/max both at 245 on sleep will actually decrease your battery life and your phones wake up performance, maybe not much. Capping your phone at 245 when asleep makes it a harder transition to awake because it makes that sudden jump when you wake it up. Setting your max somewhere over 600 on asleep, and setting it to OnDemand will ease the transition from sleep to awake.
There is no shortage of battery life tips but here's one: The auto rotate function polls for g-sensor status like once every 15 milliseconds. I use a switch on my homescreen to turn it on when I want it and keep it locked in portrait when I don't need it. This will help conserve some juice
I'm only scratching the surface here, I'm sure you do realize what a wealth of info there is on the subject already. FWIW, I use the crap out of this phone and I consistently get 20+ hours out of a charge. Good battery performance is achievable!

20+ Damn, what rom and kernel are you using? Im kinda having the same problems too. Im limiting my phone tryin to get better batt, that ****ing sucks. I just want to use my damn phone, without much sacrifice. Thanks
Why the hell do you have 4 phones running the same OS?
I'm looking for a ROM which can make my device hit at least 24 hours with light/moderate use. I know it's based on how the much the user interacts with the phone, signal strength, etc but there has to be a ROM which made your battery life amazing! I'm currently hitting about 12-14 hours with light to moderate use. I've seen people that use it the same amount and get nearly 2 days, how can I achieve this? I read somewhere that Pershoots kernel does well with extending battery life.
I'm currently on CM7 with the stock cm kernel.
Thanks for any helpful posts!
Okay so in my experience to get 'good" battery life with a g2 you need to turn off your push updates, stay off of data as much as possible, and only hook into wifi when you need it. Make sure your screen is on for no longer than 30 seconds, turn down your brightness, and set some profiles under setcpu to downclock you after you get to sub X battery life. Just make sure to increase the priority the lower your battery life goes.
The best and most consistent battery life figure I've gotten is 42-48 hr by generally not being a complete dickwad. If you flash a rom and have to download all your apps again it is going to suck you dry. I ran Cm6.1.1 with preshoots kernel for a goodly while and have pulled the same speed/battery life as I do on Virtuous with Advanced Kernel. It's taken a couple days for it to settle in but yeah, you're looking at 42ish with moderate net usage, full signal, and darn near constant texting.
Edit: Let me clarify. As your power goes down you should downclock in 5% increments. For every 5% less battery power you have, you need to increase the priority of that profile by 5%. Make a profile that is 100% priority but downclocks your cpu to 350ish max and 200ish min. Also something to keep in mind is that every piece of hardware is different. Some people can report fantastic life on the same kernel and OS. Just one of those weird machine god things.

I can get a day and a half with team villian sense ginger. The one before 3.0 best battery life i have seen yet. This is a 1.5days with constant OC no screen profiles or any kind of battery saving profiles. I would say im a slighty less then heavy user. Wifi always runs and i use gps for about an hour depending where im going. Now i normally charge her up every night but i have forgotten on ocasion and made it till i got home from work the next day.

+1 on villan rom, i set an off screen OC to 300MHZ and an on screen to 1.5Ghz, and i get 20+ hours out of it with mild data. wifi off unless im home and location always turned off unless i need it.
Might give that villian rom a try, is there a specific kernel I should use? Or should I just use the one that's already on the villian rom?
Sent from my HTC Vision using XDA App
just download from the current thread, the 1.5 version, it has an kernel that OC's to 1.5GHZ and works well.
i would download as is, and if you like, play with the kernel later on if you really want to.
Or if you like sense get sense ginger. Im not sure how you can get the older version but you could try the new one.

He is right, but lots of us has been through several ROMs and I can say that from the look of it all the ROMs use lots of battery life due to all the running processes. If you end up finding a ROM that supports your needs post it and let everyone know. Hope I helped
hi guys im a newbie about android. yesterday i have updated my phone with motorola update gingebread for ms2 retail (italian).
I wish to know if is there a kernel for improve battery duration, i`ve searched around and on this forum but have found nothing.
thx!
edit: around i`ve read that i can improve my battery life installing setcpu or milestone overclock and setting up some profiles with cpu and monitor differents frequences.
anyone tried it? is this helping battery life and are these app compatible with new stock gingerbread 2.3.4 for ms2 retail?
any advice guys? im still searching around, can someone address me to on the right way(aany guide or thread talking about this).
I have never had any battery issues and still don't. Still rockin' at about 23 hours non stop with WiFi and 3G on and brightness set to automatic.
I actually realized I didn't even undervolt yet, so I guess battery performance might be improved.
hi dude, thx for ur reply.
do u use a custom rom? or different battery?
as i told i use a ms2 unbranded with stock rom, now updated battery seems going better now than when i was on froyo but still low hard arriving in the night if i use wifi
The only kernels we can get on ms2 are the stock ones thanks to the locked boot loader. If you downlooad milestone2toolbox from one of the threads in the android development forum (pretty sure miui has it on first page), it has a pretty nice over/underclock feature. And custom roms will help you battery life somewhat, however if you are like me and can't put your phone down, and are on it all the time, you'll still only get like 4 - 6 hours battery life .
Once and once only, I squeezed out 24 hours, I was very proud. Granted that I was bored out of my brain, but still managed about 15 minutes of gaming, a couple calls and about a dozen sms, 1/2 hour browsing xda, another half on android market.
And I don't know about other people's experience with it, but Juice defender seemed to have actually DECREASED my battery life - quite significantly I might add. A friend at work tried it too and unistalled that same day from the amount of drain he got :/. I suspect perhaps its more useful on eclair, but with gingerbread (and maybe froyo) it is redundant.
Moral of the story - underclocking is your friend for battery life. I'm underclocked to 800 mhz and barely notice any performance loss - even when playing NOVA hd

hey dude thx for ur reply!
ok ill try tool box. yeah i think same on juice defender.
well i`ve not calibrated my battery and dont know if it helps, but my battery life especially when use wifi is very low!btw ive noticed that the over 60% of consume of the battery juice is about screen. I was thinking of underclock gpu too when i dont use games etc... is that possible on milestone 2? i`ve found nothing around about that
I didn't know phones could have gpu clocked? Unless you were just speculating
Yeah the screen is a bit of a power hog, but just remember that it has back lights lighting it the whole time your using it, so that's the reason it drains so much. So either setting screen brightness to low or automatic is a plus. Obviously low is best but its pretty hard to see . Autosync/gps will push apps like facebook into the lead too.
I'd recomend one of those recharable portable batteries that has a usb out port, they are so handy in a pinch it's a bit of a decent investment too since you can just plug whatever usb cable you have to charge any device really
Oh and using your phone's internet is a crazy, crazy drain to the battery!

Finally got my desire z, it came with 2.3.3 unfortunately. So as yet not rooted or anything as I don't have the time just now.
Was just wondering what people's current drain was, mine seems to be around 32mA on standby which shoots up to between 200-350mA with screen on, brightness at 12%.
1. Would this be considered normal for stock?
2. I also am having the dialler high useage issue, tried most of the fixes but still quite high, was this ever resolved properly?
3. Thinking of romming to virtuous sense 2.0 if it will improve the battery drain, can some of you give rough screen off current drain figures please? Especially sense based roms as that's what I would be using.
Thanks.
I used the 1350mAh battery for a long time and then finally caved in to get a Mugen Power 1800mAh. Since then Sense based or not my drain doesn't go below 15% for a full day Wifi (always on), Data (always on - when no WiFi) and Bluetooth on for 6 hours (during travelling).
I would suggest you do the same to get the peace of mind everyone deserves but HTC wasn't caring enough to pack in.
With a 1800mAh battery you don't even have to worry about anything, no matter what you try.
Interesting. It really makes that much of a difference does it?
Where do I get them?

Yup it does, mine is a 1900 mah from chi chi tec
I got my Mugen 1800 from eBay. But you can get it from their website directly. Beware of fakes! If it's too cheap to be true, it is.
Here's a tip, you really don't need much brightness indoors and turn off GPS, wifi when not using it, and screen timeout to like 1 minute.

Way ahead of you, my brightness is always 10% ish, same with gps and wifi, fb every 4 hrs and mails every 6.
I'm now rooted with S-OFF on gingerbread stock. Gonna install cwm and maybe try a different kernel. Any recommendations as to one which will work with stock?
No idea on the kernel, but I really do suggest a bigger battery. I just went back to the stock one for a few days and it was noticeably less.

Just use glite problem solved lol
I'm using bulletproof miui and my standby sits around 28mA with around 150-250 mA regular use. My battery lasts a full day with medium usage (4h screen on, wifi on, 18-20hrs unplugged total). I would say you're sitting a bit high with your battery consumption and could benefit from an undervolted kernel. I have my cpu clocked at 1ghz max these days..
Hope that helps!

I'm thinking my battery just hasn't settled yet as I'm using the battery monitor app and it tells me I'm getting a 32mA draw with screen off but my battery is lasting only around 18 hours with light use and a lot of standby time. For a rough calculation: 1300mAh/32mAh = 39ish hours (standby), deduct 10 hours for messing around, I should be getting at least 24 hours I would think (very rough calculation).
Have only charged it maybe 5 times so far, its probably still being worn in as it seems to drain damn quick on standby at 32mA.
Possibly, do you know your voltage levels for each clock speed? I can get a good 35+ hours with light use and standby at night (~3 hours screen on with wifi connected always)
Sent from my HTC Vision using xda premium
I'm still on stock just now. Just realised that 'always on mobile data' was on, so I have turned that off as my sync apps will still work and I don't use push email. I'll try that over the next few days and see if it makes a difference as well as the battery getting charged with more cycles to break it in.
If that still leaves it to be desired, then I'm gonna put virtuous sense 2.0.0 on and use underclocking as that made a massive difference with my old wildfire.
What rom are you using bik_jack?
I'm using bulletproof miui but was getting roughly the same voltage numbers with cm7 nightlies before I switched to bulletproof in June.
Both underclocking down to 368mhz with the default undervoltage settings used in tsubus' kernel.

i made a barebones stripped ROM based on the newest tmo OTA, i made optimizations to get better battery life, and stripped tons out to get the most ram possible, and keep the ui fast and snappy.
my newest version 1.3, offers the best battery life in any rom that i have ever used, its super fast (no need for OC), offers the most free ram and is located here :
http://forum.xda-developers.com/showthread.php?t=1324616
give it a try! im sure it will get u more battery life
Of course, now I've realised that my network (3uk) no longer have a 2g contract with orange, so all this setting does for me is stop me receiving txts and calls with it off. Tch. Looks like I will be trying virtuous after all.
The standby battery drain doesn't make sense at all, almost like my battery isn't really 1300mAh.
I use an Anker 1600mAh battery that I got off ebay in my DZ. The seller had a sale of 2 going on for $15, not a bad deal. link to it is here
It's listed for the Incredible 2 / Incredible S, but it seems those batteries are a perfect fit for the Desire Z / G2. Doesn't need any aftermarket casing or modding.
Right now, I am using the ICS beta by tazinator and yesterday I got ~12-13 hours of playing around with it very heavily. My battery can last 22-28 hours with moderate and light use on a normal day.
Sadly, I don't have any if those issues you listed, Dialer usage and such even with CM7. Used to use virtuous sense but went over to AOSP/CM7 instead. Found AOSP being more nicer on the battery, but that's just my feeling - I tend to think Sense drains more battery.
Yeah I think sense is a bit worse on the battery but I've really come to love sense, never really got on with cyanogen roms.
Turns out I was wrong about the data always on and my provider, it all works so I'll keep testing that before I start with roms.
I know mugen batteries are supposed to be good, any other recommendations for brands? I'll check the link out.
UPDATE: If battery monitor is to be believed, my global standby estimate is increasing with every charge, so maybe it is just a case of breaking the battery in. Now at 21.5hrs, I'll continue to monitor the situation, this might also be due to the change of data setting as well.
Since the beginning of Android one thing has always been an issue with some of the greatest ROMs.
........................Battery life.
Every day lives are drained away by the pleasures and features of such fantastic ROMs... and such things at time seem so hard to bare that we try to change the lives of our battery by going to a different ROM.
So now you have a chance to make a difference, nay, an opportunity to change the lives of many...
This thread is strictly for how to save Battery life. CM9/AOKP have amazing battery life by themselves (but yet can always be made better) But for those on MIUI (Not so great battery life) this will be really useful.
Understand that everyone's device is different and although you may get 15 hours off MIUI/AOKP/CM9 others may only get 4 from them.
Post what it is that helps you achieve maximum Battery life. You may be the one to solve the cure to wowhowdidmybatterylifedroptwentypercentinanhourosis.
Be sure to include:
1. ROM
2. Kernel
3. Tweaks that have been applied through ClockworkMod
4. Apps used to save life
5. What battery you use
6. How long your life lasts
7. Anything else that you think may help

1. CM9, although i think aokp does better.
2. Samurai Kernel, although just about any other ICS kernel should help. The biggest thing that you can change between kernels is the Governor and I/O depending on these two will determine how the CPU runs and in effect will determine battery life. Conservative is just about the best for battery life. If you need slickness and not too worried about battery Ondemand. If you want the best of both worlds i Think Wheatly is a good compromise. Also I/O , Sio is "simple" but VR is flash based so it tends to be the best. Otherwise Noop/Deadline. Also voltage.. undervolting will help limit the amount of well voltage to the CPU. So the lower you can get it the better.
3. Dont have tweaks i apply through CWM but i Run the V6 Supercharger, 3G turbocharger(optional), and the Kick Ass Kernelizer from Zeppelin.
4. I cannot stress this enough, Apps that say they save battery... run... which uses RAM and Resources... meaning its running trying to save you battery, Using battery. Which is stupid... and useless.
5. I have two a 3500Mah and the stock 1.5 year old 1500mah.
6. Typically with 3 hours of display over a period of 15hours (1500 mah) and around 5 hours of display over a period of 22 hours (3500 mah). However this is on wifi, 3g would deduct these a pretty good amount if you have sucky speeds.
He needs to get over it... lol. The only thing that truly saves battery life is managing your connections. There is no magic bullet unfortunately.
PLEASE! Don't tell us to turn off data and never sync the phone. Obviously if you don't use the phone the battery will last forever. I need a phone that can do the following:
Receive emails and texts as they are sent. (I use exchange push)
Last 18 hours on a standard or 1800 mAh battery.
I can just barely make that with stock FC09, I'd love to run ICS but with either CM9 or AOKP I barely make 10 hours.

Why must people post unhelpful comments such as the one above? I don't understand the logic there...
anyways since this was aimed at miui I get pretty good battery life with it... (3.5 hours screen on time) nyan v5 ftw! No special features... uv a lot (won't list my settings cuz every phone is different) and no oc... used to use jd but, it saves more battery if you just switch things off manually... really though until I flashed nyan my battery life was atrocious, but now just about on par with the peoples rom (4.5 to 5 hours screen on time!) Oh yeah, all this with the stock battery...

I can just barely make that with stock FC09, I'd love to run ICS but with either CM9 or AOKP I barely make 10 hours.

On aokp with 1800 mAh i can do about 3Hours of screen on time and 15 Hours of battery life and my phone was awake 75% of the time.
Screenie was at 15%
This was stock Everything Except ROM haha

Think about if your screen was on while the device was awake..your time would be cut in half

Oh my good golly gosh.
I just realized the best battery life I ever got was on DK28.
So take that. Let's go Frankenstein.
1. CM9 KANG June 02 build.
2. Stock
3. Services for V6 and Search Key Remap
4. Ha!
5. Stock. Came with device...need new one.
6. Depends on use. But I usually get the estimated six hours consistently.
7. If you're going to use a task killer just use the built in one. Overclocking is bad, and in my experience so is undervolting. GTalk, official Facebook application(especially this. Even with notifications off it still is always going), G+, and more are always running and are a drain. No live wallpapers, and no widgets that require constant updating. As much black as possible. Don't use third-party batteries. Obviously turning off 3G, 4G, sync, and such will dramatically increase your battery life.
WAIT! Why am I writing this? There is a freaking optimization guide. Why does this exist? For ****s sake.
Running AOKP build 36, stock, FC09 modem 15 hours running takes me down to 50% batt hour of screen time, constant crappy wifi connection in an area with crappy cell signal sync for everything but email and g chat is every 2 hours (weather and all that). Big thing to save batt for me was turning down my screen brightness. I was also getting crappy battery life till i let this rom install run the battery down to 5% twice.

Why must people post unhelpful comments such as the one above? I don't understand the logic there...
anyways since this was aimed at miui I get pretty good battery life with it... (3.5 hours screen on time) nyan v5 ftw! No special features... uv a lot (won't list my settings cuz every phone is different) and no oc... used to use jd but, it saves more battery if you just switch things off manually... really though until I flashed nyan my battery life was atrocious, but now just about on par with the peoples rom (4.5 to 5 hours screen on time!) Oh yeah, all this with the stock battery...

By no means was I saying never enable your 3g/4g.. but the fact remains that the single best way to conserve your battery life is to be smart about managing your connections. I.e. not leaving it on ALL day and to only turn sync on when your actually checking your e-mail.. be that through an app like juice defender or manually toggling. If that's not more helpful than what you posted (UV a lot and don't overclock??? Duh.) than my bad bro!

Something we can all get behind here... I remember I used to get 24+ hours on froyo w/o customs kernels. Le sigh..

1. CM9, although i think aokp does better.

-CM9 still seems cleaner, but AOKP seems better.
ÜBER™ said:
2. Samurai Kernel, although just about any other ICS kernel should help. The biggest thing that you can change between kernels is the Governor and I/O depending on these two will determine how the CPU runs and in effect will determine battery life. Conservative is just about the best for battery life. If you need slickness and not too worried about battery Ondemand. If you want the best of both worlds i Think Wheatly is a good compromise. Also I/O , Sio is "simple" but VR is flash based so it tends to be the best. Otherwise Noop/Deadline. Also voltage.. undervolting will help limit the amount of well voltage to the CPU. So the lower you can get it the better.

3. Dont have tweaks i apply through CWM but i Run the V6 Supercharger, 3G turbocharger(optional), and the Kick Ass Kernelizer from Zeppelin.

-I don't use the supercharger, but I do apply the same oom ram mods. These help close unused apps when they exceed the applied limit. Based on my experience, it's kept apps under control.

4. I cannot stress this enough, Apps that say they save battery... run... which uses RAM and Resources... meaning its running trying to save you battery, Using battery. Which is stupid... and useless.

-THIS +9000! An app that spends all of it's time stopping other apps is wasting just as much "battery." I maintain, Advanced Task Killer, with NO, I repeat NO AUTOKILL. Set a widget on your home page, tap it occasionally to make sure everything is closed. Same effect as the built in task manager, but one single convenient tap.

-I use two stock 1500mah batteries and one 3500mah. My wife has the same. All are about 1.5 years old now.

6. Typically with 3 hours of display over a period of 15hours (1500 mah) and around 5 hours of display over a period of 22 hours (3500 mah). However this is on wifi, 3g would deduct these a pretty good amount if you have sucky speeds.
Click to expand...
Click to collapse
-These numbers are pretty much the same for me. I almost always average 3 hours display on the stock battery between games and internet. 5-6 hours on the 3500, but I'm pretty sure it's not reaaallly the 3500mah it claims to be... . I NEVER turn off wifi or 3G, but google autosync is off until I edit my contacts.

I don't turn off my connections at all and get great battery life... and seens how the op states don't say anything about disabling 3g or anything id say your comment was the least helpful on the thread... but at least you tried... don't get into a battle of witts with me, I'm afraid your unarmed...

Firstly, I'm not trying to get into a pissing match with you. Its pointless. Secondly, the op makes no mention whatsoever of connection status. Thirdly, while you might get decent battery life w/o doing it.. I guarantee you'd do better if you did. Straight facts.
Edit: I am armed. With a small slide out keyboard.
Please follow the format specified by the OP. List the 7 items. Bickering in this thread will not be tolerated.

Be sure to include:
1. ROM
2. Kernel
3. Tweaks that have been applied through ClockworkMod
4. Apps used to save life
5. What battery you use
6. How long your life lasts
7. Anything else that you think may help

1. CM9
2.ShadowKernel (I find nyan colonel to be a little more draining) SIO, conservative
3. None
4.System Tuner Pro configured to UV, under clock to 400mhz on screen off, to close apps that don't automatically restart themselves, configure "auto-kill" so its not as aggressive with killing apps that just stay on, and a few sysctrl edits that I honestly don't think make a difference.
5.stock epic 1500 mAh, my sprint store wouldn't give me an sgsII battery
6. 12-18 hrs depending on use, though it has definitely drained quicker
7.be easy on data! (There kennyG) turn off wifi when your not near your networks, turn off mobile data, Bluetooth, and autosync when your not needing it. (Unless you absolutely need PUSH email for your job or whatever though honestly as far as my job goes if its important enough for me to need the message immediately they will simply dial my phone number. Yeah I'm old fashioned.
- Cm9
- Shadow kernel
- No tweaks
-1800 D710 battery
- I get 15-20 hours depending on how much music I stream during the day.
- I got the biggest boost by using the profiles in CM9 to optimize my connections and syncing depending on where I'm at during the day. I have Wifi at work and home, so I have it toggle my data off during that time period and vice versa when I'm mobile.

Using AOKP with shadow kernel.
Best thing I did to help with battery life was to turn off all notification options in the FB app. And I set haxsync to download photos only when plugged in.
