So I've had my evo a couple months and just realized how bad my battery is compared to people on here. Some people I've seen can go more then 24hrs without charging, id like to know how?
Basically I charge my phone all night wake up at 7 go to school (don't get great service if that matters) I might have the screen on and texting/internet about only 25% of the day. Then by the time I get home at 3 im around 20-30 percent? I'm running miui rom i also have my email refresh to never, have setcpu to the lowest when screen off and screen brightness usually 50%. Also I'm using the stock battery but going to buy the gallios 2000mah or whatever from ebay.
Sorry for writing a book i just need better battery. I've seen threads everywhere about this but I just want to hear everyone's tips. Thanks

yours just like me, my phone is on 8 hours (while inm at school duh ) and i say i use it for about 2 hours while im at school. i use a sense rom (AOSP roms give me horrible signal) and when i leave school im about 90%-96% . i use SBC kernel and give it 3 days to settle in you wont see the battery life instantly. try it out
Thanks. Will an sbc kernal work on miui? I've never used a kernal...do u just installed them like roms? If so what data do I wiped? Sorry for all thames questions.

I reccomend the savaged zen HAVS CFS kernel...I'm on stock battery on CM7 nightlies / with WiMax, and I have had my phone unplugged since 8am, and still have 48% left...I'm able to go about a whole day.

I also have a question on kernels while we are talking about them. Is there a certain way to install them or do i just install the zip through the boot screen? I installed the newest ziggy kernal, dated nov 24th but didnt notice a change in battery life. Any help?

Thanks. That kernal will work with miui correct? And I just wipe cache and davkic or whatever right not battery stats? Then installed it like a rom?
Edit: I went to that site but I don't understand which one I download? Sorry I'm a new to this

Download the 8th one from the bottom
its named :
Savaged-Zen-V0.0.5-CFS-HAVS-SBC-WiMAX-Froyo-Signed.zip
and yes it works on miui clear cache and dalvik cache and flash the bad boy. you might see bad battery life for hours or day but kernel has to get use to the ROM it will start to work out. and once your phone gets to 100% on battery it is still charging
Is that the same for all kernels? They take time to adjust to the rom? Or just the kernel you are recommending right now?
All kernels take a couple days for the to "set in."
Ya that's the reason I want it I let my phone charge overnight to 100. So with this rom it will keep charging all night? If so ur saying it won't work in the morning if i install it tonight?

You can use SBC on MIUI, I'm using the one posted in this thread already, works great.
Can someone link me to the sbc kernal I would use on miui? I'm new and don't really understand which one to choose

1. Boot into recovery
2. Wipe cache and dalvik cache
3. Flash your current MIUI rom (I've had the best results flashing kernels this way)
4. Flash the kernel.
5. Boot
6. Drain your battery low and boot into recovery and wipe batt stats.
7. Boot back up and let it die.
8. Charge to full.

What hardware do you have? If you have an 003 or 004 you may have issues with the screen waking up with this kernel. If so, flash the Savage 1.6 CFS SBC http://dl.dropbox.com/u/18860340/Savage-Kernel-v1.6-CFS-HAVS-WiMAX_SBC.zip.
Set your setcpu profile to conservative. You'll get the best battery life that way.
I'd recommend downloading Battery Monitor from the Market and putting the widget on your homescreen. When the mAh drops into the teens, your battery is full.

Im planning to go back to http://forum.xda-developers.com/showthread.php?t=935275 CM7-GX4(EX+4G), is that the same one you are using, if so, are you using another kernel then the one suggested? If so which, because I also only get about 10 hours on cm7, I want to use this on my main evo. Miui 1-14 is the one i use for my ipod evo it last 45-50 hours on avg.
Just to jump in real quick, I am using Myn warm 2.2 and the battery life is amazing and I don't even use a different kernel than stock. I'm talking twelve hours easily with heavy use

can you provide details? like how long it takes to charge/discharge? if you're using a custom kernel or what rom you're using? can't help if you just give a vague description of the problem
SBC stock HTC #15 kernel, fresh ROM, it charges 10% in like 10 minutes, and dies under 6 hours and all u do is text nothing else!

If you leave 4g on it will eat your battery in 6 hours easy
Swyped from a galaxy far far away......
hmm have you tried calibrating the battery? or try a different kernel? sometimes problems like these are kernel related. I know that certain kernels have drained my battery faster than others.
Nope don't use 4g, & when phone is idle it dies 10% in 8hrs of idle but after that .. man under 30 minutes it goes down another 10% or less
Sent from my PC36100 using XDA App
well honestly that's pretty normal especially for a sense rom but maybe if you try calibrating the battery and erasing battery stats, that could help you out. Also try not to have GPS on unless it's necessary. That also drains your battery. Or try a different kernel like netarchy's kernel and if it's a non-havs kernel then combine it with setcpu.
What are you using?
Sent from my PC36100 using XDA App
well I'm not on a sense rom so I'm running a savaged-zen kernel but when I WAS on a sense rom I used this one http://qap.la/~netarchy/netarchy-toastmod-4.3.2-cfs-nohavs-nosbc-noUV-universal-signed.zip
y/netarchy-toastmod-4.3.2-cfs-nohavs-nosbc-noUV-universal-signed.zip It's cfs, has no havs so I could use it with setcpu and wasn't SBC because I don't like to mess with my battery that way.
What rom are you on?
Sent from my PC36100 using XDA App
I'm on cm 6.1.2, I use the stable .0.4 savaged-zen kernel without SBC and with Wimax. and I average about 20-22 hours every day with moderate-heavy usage.
Why not use cm7 wimax?
Sent from my PC36100 using XDA App
If it's charging too fast and dropping to fast, I would guess you need to calibrate it.

For some reason I just prefer cm 6.1.2 but I'm fine with waiting for the stable cm7 to come out. I use a kernel with Wimax because all of the savaged-zen kernels are Wimax capable.
Honestly though, try calibrating the battery and then either use the kernel you have now or a different one but always remember to wipe cache/dalvik-cache
I'm about to flash cm7 wimax, and what can I have my brightness set to?
Sent from my PC36100 using XDA App
you can use auto brightness. I usually keep it on the lowest because I find the others to be too bright for me personally and when I'm in bright places I set it to auto. By the way if you use the savaged-zen kernels, set the wifi sleep policy to never to avoid random reboots.
Any one have ideas for battery saving kernels?
Sent from my PC36100 using XDA Premium App
Well... everyone is different, and all phones take each kernel different. It all depends in your usage and what things you're running. You have to try out different kernels and see. You can try SBC type kernels they work great on my phone. Give that a try. Search and look for kernels in the search box. Hope this helps

might want to try netarchys kernels they are great....hes the best
Savaged Savaged Savaged!!
Savaged-zen is an amazing kernel, plus it has SBC which I love. Great battery life, quick. What more could you want?
I personally have good battery with the Tiamat kernel; sbc available if you want it.
OK...first post so here we go. Been using the destroyer rom and the latest sav-zen kernal (v.0.2.0 cfs) for the last two days. My phone responds pretty smooth even being underclocked. The battery life is great compared to stock...yesterday with light-moderate use I was at 17 hours with 30% left. Today over 12 hours of light use but jumping in and out of roaming for about four hours and I'm at 64%. Great job to all the devs

Ok, I have an evo, running fresh gingerbread rom, and.....the battery still blows, i have tried most if the popular roms and was not impressed, i have set cpu as well, i dont see any change, im not really that good at this stuff so can somebody PLEASE hook me up with a method to make my phone last a day, roms, kernals, set cpu profiles, anything.....thank you all greatly
Sent from my PC36100 using XDA Premium App
If you are on 4g, wireless tether, playing roms, texting, and making calls, then don't expect the phone to last more than 5 hours.
First thing you need to do is start off with a fresh rom... pick your favorite so far.
Reboot
Install kernal (I like tiamat for AOSP or Netarchy for Sense but I suggest you try your own)
Reboot
Install undervolting script
Reboot
Open Google Talk>Settings>uncheck automatically log on then log off google talk
Install SetCpu
If you don't really game or anything then lower your voltages to 125 min 700ish max (you can be more aggressive if you want, but I wouldn't)
Charge phone to a 100%
reboot into recovery
wipe battery stats
Use your phone till it dies
Recharge
I think you will now have a strong phone that can last a good day depending on how you use it
If you still want to increase your battery life after all that
Lower brightness
lower the updating frequency of stocks, accounts, etc
make it a habit of turning off radios when not in use or install Juice defender
Create profile in SetCPU to lower CPU when screen off
All really good suggestions above...
but sometimes it could be just the battery it self... if all else doesn't work try another battery. The previous stock battery was horrible for me even after trying all the settings and etc. Once I got a new battery and did all the setting changes this thing is ready for anything.
What rom are you using? For the best battery life with a rom like cm7 I recommend using an SBC kernel from tiamat 4.0.2 SBC+ and give it a few days to settle in...then when your battery is low around 20% or less charge it for at least 4-6 hours while phone is sleeping..then turn off your phone while plugged in and charge for another hour..then unplug til green light goes off then plug in again til light goes green REPEAT 10 TIMES! then turn on phone while plugged in wait 2 minutes then unplug and battery is improved...do it every time you charge it from low %... this is for SBC kernels...also follow what the others said above me... I use an extended battery on conservative running it at 245 and 768 its been 12 hrs and I'm at 71% with moderate to heavy use...hope this helped

wow, seems pretty involved, ill give this a shot, im running Fresh 4.0.0.4 rom now, is there another rom i should be using otherwise? i dont use the tether, i just do the youtube thing, facebook,email text and call, nothin to extensive
Try Evodecks 1.0 or 1.2c... Very nice and everything works on it... I'm using Tiamat 4.0.2 w/ sbc, its been 23 hrs and still at 59% thats moderate use though! But just search around and eventually you'll find something that suites your taste... MIUI is also a good rom! Just my 2 cents...

I cannot run a undervolted kernel on my evo for some reason, it doesn't play nice. I liked tiamat on my previous evo, was the only one I ran. while I have tiamat running i have about a minute before it reboots. My question is can I use vipermod to restore voltages to stock/stable. If so what voltage should I enable. I'm useing an extended battery 3500, if that makes a difference. Also if that's not possible what kernel do u recommended I flash to get better battery life?

What ROM/kernel combo do you have? how are you flashing them? Are you making sure to pair sense kernels with sense ROMs and AOSP kernels with AOSP ROMs?

Sorry, it may sound like a retarded question for me to ask. But you'd be surprised at how many people are running sense and flash an AOSP kernel, or vice versa. It's always nice to get the obvious issues out of the way in order to focus on what the real cause is.
MIUI is one of the ROMs I've never really used. Make sure your battery is calibrated. That should help a bit with battery life. I'm using Savaged Zen on mine with CM7 and it works amazingly well. As far as the undervolting issue.....I am not too sure as to what is causing that.
What method do you use to calibrate. I've never done that. All I've ever done is wipe battery stats
Sent from my PC36100 using XDA App
Charge battery to 100%, enter recovery, wipe battery stats, let phone COMPLETELY discharge (till it turns off), then recharge to 100% again and use normally.
