Well my phone charges fast but it also dies fast.. any help?
Sent from my PC36100 using XDA App
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

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?

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.
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

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...

Hi everyone, as the title states, I'm trying to determine which kernel would be best for me. I'm currently using salvage mod 1.4 rom, and I love it, but my battery drains a little faster than I would like. Any suggestions would be great. Thanks!

Try a Tiamat or Savage-Zen kernel because they can both work with vipermod and V6 Supercharger.

Tiamat 3.3.7
and dont forget when flashing a new rom to recalibrate your battery.
tiamat 4.0.8
Thanks for the tips! I think ill give the Tiamat 3.37 a shot later. Noob question, but what is entailed in calibrating the battery. And do I flash kernels the same way as roms? Thanks for the help!
Sent from my PC36100 using XDA App
You calibrate it by following some steps with a series of plugging and unplugging the phone to get it to true 100%. You can use an external charger to avoid all the crazy steps.
Once it's 100%, go to recovery and wipe battery stats and that's it.
World peace with no regard for human life.
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
