Helpp! Terrible battery life...

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?

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?

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.

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.

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?

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.

WHOA it's rare to see someone say that the battery life is horrible in this forum. You should try a new fresh wipe and install, and try different kernels.

Try darksides super wipe then re install juggernaut ROM. Make sure not to run setcpu or any other cpu apps, I was having bad battery drain running setcpu.

i actually think those "battery saving" and task killer apps uses up more juice than saving ... i had juicedefender ultimate and i noticed my battery drain when it was enabled .. i deleted the app and ive noticed a great improvement on my battery .

Agree
I was also getting horrible battery life on the Juggernaut roms. I tried the bullet kernel, synergy, and faux kernels with all sorts of different ways to reduce battery consumption such as underclocking, undervolting, uninstalling bloat, and removing apps from startup. No matter what, my phone would always be dead by the time I came home from work/school (I'm usually away from home from 630am until 800pm).
I recently started using the DARKSIDE rom/kernel in the hopes that it would provide some better battery life and I am actually getting significantly longer usage times. As of right now after ~15 hours of time spent off the charger and with moderate use (~500 texts/day, XDA app, FB checking, random Internet usage), I have just under 40% battery life remaining. I must say I am very impressed with this rom and give the developer TDJ mad props.

So here's my battery life with Eugene's Macnut ROM:
Compared to this (Juggernaut 4.1 with ICS Ultimate Theme):

I run juggs with TDJ Darkside kernel, kernel makes huge diff

I am running Juggs 4.1 as well previously with the FAUX123 kernel and decided to try out TDJ's Darkside kernel. Wow, huge difference, highly recommend. I use system tuner app to adjust my speeds but main thing in system tuner app is to go into boot settings and set screen-off to powersave governor and max frequence to 800, 500 etc.
I also run easy bettery saver and that helps as well. Battery life is best I have ever had with my G2 and I got it first day it came out and have run most all of the rom's kernels on it. If you can I would suggest running TDJ's Darkside rom as well. I would but just don't want to reload again at this point.
DK

I'll try darkside rom and see if it fixes my battery drain problem.

Thank you for this, I wasnt aware of that, what do you use to change your clockspeed when your screen is off? I recently switch from an iphone and unfortunately battery life seems to be something I have to actually think about now. I know its a faster processor and a bigger screen so I get it, I just never had to worry about turning off wifi and things like that before. I currently am running beastmod 4.2 with darkside kernel. I have 9hrs on battery at 41% with 2 hrs and 15 min of display. Im not really interested in speed at this point so I thought setcpu was a good thing to use to underclock and use less battery. Can you recommend any good alternatives or should I not bother with setcpu type apps. Thanks in advance

On darkside... Not the current one but the one before it... I think it was version 1r2 or something like that. Battery is great, better than juggernaut. I have bluetooth and Wifi on all day

They gobble up a TINY bit more CPU (probably no more than 1% throughout the entire charge) at the cost of managing your data settings. It saves juice primarily when your phone is idling. It pings, it checks data thresholds. The main idea is that it turns off 4g/wifi when you're not using it, and back on when you are. This requires a little but of CPU, but you end up having a battery that lasts much longer.
There's never be a time when you're using your phone 100% of the time on battery. There's ALWAYS idle time.

[Q] What's the best GB aosp kernel for battery?

I'm having major battery drain with the latest CM7 stable release. I've lost 25% in standby in about 90 minutes....my phone was charged while off to 100% last night, and when I turned it on I left it alone....didn't even turn the screen on. when I came back an hour later it was at 78%
Can someone please recommend a good battery saving kernel, please....I'm pulling my hair out finding one. For such a popular phone the choices seems really sparse

Every phone handles kernels differently but one of the best ones so far on my phone is here.

I agree with this kernel. I use SBC as well, it will stop the 10% drop in battery whenever you unplug it.

Thanks for all the wonderful responses, everyone!! I'm giving mason a shot first, since it seems so popular
I'm trying Mason G - v0.14 sbc uc'd to 729mhz, powersave gov....but I can't find any options to uv/ov. Does set cpu not work properly with this kernel? What app/script should I be using?

for undervolt if it is sysfs HAVS enabled you need to get vipermod. If it just says undervolt then it may have a pre-set undervolt determined by the dev.

On GB is was running this same setup and my battery life was nothing short of amazing. I had a good 15-24 hours depending on use.

best cm7 kernel?
i just recently started using mason. its pretty awesome. before that i used tiamat sbc also no problems. just try which ever ones you think you may like every couple days to see which one works best for you. i also give the kernel about 10 minutes to bake in every time before i unlock it. i dont know if thats been proven to help but it cant hurt and seems to work well for me.

I've been running mason sbc for about a week now. I had to use a combination of vipermod and smurfed out scripts to get the kernel set where I wanted it. I noticed the kernel was set for BFS by default, which I've never been a big fan of, due to its power consumption....so smurfed out let me set the scheduler to CFS, which is much more conservative and doesn't sacrifice any i/o speed, imho. Then I used vipermod to uv -25MHz so it wasn't such a battery-hog. Underclocked, undervolted, and set to CFS seems to be my winning combo!!! I get no less than 3 hours of constant screen time (streaming video, browsing the web, etc.) and enough standby to last me all day so I don't have to carry my charger with me anymore.
With every other android I've ever owned, setcpu does everything I've mentioned changing in this post...so when it wasn't working, I had no idea what to do.
Thanks so much guys!!! I couldn't have done it without all your help....HTC is in a world all its own in the android scene since they use so many different things that no other manufacturers do. It made me want to pull my hair out until you guys came along to help me out

Poor battery life with juggernaut 5.0 & darkside v1 kernal

its been 3 days since i rooted my phone for the first time due to battery life issues. the first day my phone lasted for 10 hours. after a full discharge and full charge I've been experiencing horrible battery life again on medium usage. only getting 6 hours of battery life. what do you guys think would be the cause of this??? everybody is getting better battery life and mine seems to be horrible still.

I have never found juggs to be a battery friendly ROM. It's a power ROM. Better for gaming, shooting live video etc. If you want the 15 to 20 hour battery some are getting then switch over to darksides ROM DIGITALWARFARE. It's powerful enough for gaming just not like juggs.
Also usage plays a roll to. If your gaming for 4 stright hours don't expect the phone to last that long because no phone will. Running Juggs with darksides kernal is kinda doesn't mix.

Download 2x battery from the market, it's done wonders for my phone and i use it with any rom i flash. Not to mention i ran that same setup for quite awhile and the maximum time out of a battery i've gotten comes using juggs 5 and v1 darkside kernel.

I'm running Juggernaut 5.0, with Eugene's Streamline kernel. I'm getting about 17hs. I'm also OCD, so I play, and tweak every setting possible. I game a lot, and usually get about 6-8 with that. It depends on a lot of factors though. I agree though, it's kind of an oxymoron to use Darkside kernel with that rom. They kind of clash.....I guess you could say, as far as battery goes anyways. I had the same issue when I used that kernel. Just my experience anyways. There's a lot of setups you could go with, so. Best to just test everything once, till you find your happy place.

what are you using? are you experiencing poor battery life as well?
Sent from my SGH-T989 using XDA

Your battery life also depends on a number of other factors as well. Do you have animations on or off? If they are on, turn them off. What brightness is your screen? I turn mine all the way down. How many widgets are you running? I don't use widgets. Is your phone constantly syncing with Facebook, Twitter etc? I only turn my sync on for Gmail and Google. Is your GPS on? I have mine off at all times. Do you stream a lot of music/videos? How many programs do you have running in the background? I make sure everything is closed or off except for the programs that need to be on. If I need to use a program/app I will open it, I don't need it constantly running shortening my battery life. Etc Etc.
I also recommend using the app Juice Defender. Yes it runs in the background at all times, but, it greatly improves battery life. I use it all the time and it's fantastic.
I typically have my phone on for 15-17hrs a day and by the time I go to bed I still have over 50% battery left. I am currently just on a stock ROM and not Juggs, but my results with Juggs were around the same as well, even with the Darkside Kernel. Peace

Juggernaut + synergy + juice defender on aggressive mode = awesome battery life.. awesome enough for you to have multiple MiniBaths. :banghead:

I'm running Juggernaut 5.0, with Eugene's Streamline kernel. I'm getting about 17hs. I'm also OCD, so I play, and tweak every setting possible. I game a lot, and usually get about 6-8 with that. It depends on a lot of factors though. I agree though, it's kind of an oxymoron to use Darkside kernel with that rom. They kind of clash.....I guess you could say, as far as battery goes anyways. I had the same issue when I used that kernel. Just my experience anyways. There's a lot of setups you could go with, so. Best to just test everything once, till you find your happy place.

I lost 10-15% an hour if im not on Wifi, this phone has terrible batt life when not on wifi. Could that be why?

its been 3 days since i rooted my phone for the first time due to battery life issues. the first day my phone lasted for 10 hours. after a full discharge and full charge I've been experiencing horrible battery life again on medium usage. only getting 6 hours of battery life. what do you guys think would be the cause of this??? everybody is getting better battery life and mine seems to be horrible still. I don't have any out of the ordinary apps running either. do you think i need a new battery?
