Best Battery Life? - EVO 4G General

I have two HTC EVO 4g phones with CyanogenMod 7.2 RC1 | Tiamat_Evo-v4.1.0-sbc (CPU governor: Smartassv2 245/1152). They are also running SuperCharger v6 script for memory optimization. What I'm looking for is optimal battery life, stability, and not very much focus on performance. Already searched Google for awhile and the answers were never clear and led me nowhere.

Bump. Also need a mod to move this to Q&A.

Well you might as well underclock; no need to be over a 1152. Additionally, play with undervolting to see how much the evo can take. Keep the radios off when not needed.

I'll do some underclocking, but undervolting seems kind of sketchy. The kernels are already undervolted.

+1 for undervolting and tiamats kernels are not undervolted by default so go go vipermod lol
what kind of battery life are you getting now?

IncrediControl or vipermod? I don't know what kind of battery life I'm getting since its my parents phones. I'll try undervolting out, but just want to know if the app is safer or the script. Your only supposed to go like -50 under for both right?

Personally, I'm having fantastic battery life and performance on Swagged Out Stock N (thats the one with go launcher, and not sense), aggressive lionfish 1.8 SBC, plus using setCPU...

Ok thanks man, yeah I ended up using vipermod -50 and underclocked the phone smartassv2 - 128/652. Working out great so far.

I'm a super heavy user and have tried all the big name roms, but none of them gave me the great combined total of speed and battery life, I get bewtween 15+ hrs other roms I got normally 6-10 nitrous Rom with underworld kernal and uv'd via vipermod using extreme mod, and still runs fast and I'm oc'd to 1.03
This is a picture of what I consider normal use, heavy I consider screen on all day, normal is like 3 hrs of Pandora text here and there played games probably for about an hour total, phone calls, surfing forums, using gps results:

This worked for me. Thanks

I've had a lot of bad experiences with aosp roms... GPS not working, poor data connection, and "cellular standyby" taking up an obnoxious amount of my battery... I've tried CyanogenMod and deck 1.3 with savaged Zen and tiamat kernels
Maybe I just have bad luck?

Best battery life kernel on sense rom?

Hey guys, in your opinion what gives the best battery life on a sense ROM like Mikshift? BC's 1.5GHz, 1.8GHZ or X99, Scary Kernel, ect. Just curious what some of your experiences are..

I have been running mikshift since the beta along with bcnice20 oc uv 1.5 kernel with amazing battery life, if I forget my charger I don't even worry the standby time of that set up is just amazing ran for 24 hours on wifi with about 5 hours of using the net,tapatalk and about 75 texts and was at 50% at 24 hours of being unplugged its the only setup ill run, sometimes ill throw the 1.8 on there just to show everyone I can go that high but its never needed. I run at 1516 max 368 min conservative with a screen off profile for 806 max and 368 min no complaints here at all!! Its actually the only setup I'm willing to run!

Go with the x99 kernel without changing any settings. Just flash and leave it alone. Easy 2 days like that

What Kernel are you guys using on the lastest CM7?

How many .35 kernels are available? I'm only aware of Umaro's and the stock CM kernel. I'm trying to achieve better battery life, so what kernel are you guys using?
So far, using Umaro's, I'm getting regular battery life, nothing special. Haven't tried the stock CM kernel.
Are they any other undervolted kernels available?

There aren't any others so far. Umaro's kernel is really good for battery life, however it's not up to date with the latest kanged nightly from yesterday.
Ahh, I see. Thanks for the info.

Right now I'm using a kanged nightly with the "stock" cpu settings of 245MHz min and 1024MHz max, but with the interactive governor. With Umaro's kernel I had at 245 min, 1017 max and the Smartass governor. The smartass is pretty good on battery.
u made all the right moves all i would do is dim screen and keep runnimg apps low.
pimped out g2
btw pyromod 2.0 345 ghz min 1405ghz max on smartass. i fully charge bout 1 a day

Pershoot released his kernel the other day pretty nice and smooth

Alright I'm sleepy so this will be in rambling form but...
I've tried Umaro's and I'm not sure if it was the undervolting (which I haven't looked into tweaking) but my phone kept stuttering no matter which governor I used. I was using Htcclay's Super CM7 1.8 with cpu set to 245/1113
I also used the stock kernel that's been on CM7 with no problems and average to good battery life (10-15 hours of active use: texting, browsing, few calls, and playing the occasional game)
Most recently I've used Pershoots which I had heard worked great. I myself love it. Almost same battery life as stock kernel but everything felt just a little bit smoother performance wise.
Here's a link to Pershoot's thread:http://forum.xda-developers.com/showthread.php?t=847672
The stock cm kernel in my opinion is finally good enough that it doesn't need changed. I have always flashed pershoots and occassionally others, but it truly does not need supplemented IMHO.

You're running that on Vision? I can't seem to find it for our device.
Stock CM7 kernel here. I run 245/806 Interactive with automatic brightness. I've found that when wifi is on, keeping the cell radio @ 2G only works wonders. Wifi is set to sleep on screen off, but not when plugged in. 1 day 7 hours on this charge so far with 23% left. I would consider my use light to moderate.

I'm wondering where can I download the Umaro's kernel. I check out his github (https://github.com/umaro/htc-kernel-msm7x30) only to find out that the source is available.

800mhz is enough

Quick, and great battery. Overclocking is pointless unless you play games on your phone, or care about your quadrant score.

Yup, I agree with you

I had a Milestone for 1.5 years on stock ROM (that is 550Mhz), pretty much served most of my needs perfectly....you know, the normal stuff you use your phone for.
I rarely notice my phone is underclocked... with smartass governor, it's more responsive than stock clocks with a less responsive governor.
Battery life doesn't seem improved, but I know that my weak signal is causing the problem here.

I Sunni it's different for me.. When in use it seems to drain about the same but last night I set the phone down around 11 worth 84% battery life and got up at 6 with 78% still and that's setting the governor to smartass
It's bad for me because my phone goes without signal about half the time in my apartment. I'll be moving soon so it's not a huge issue, but it is kind of disconcerting to feel my phone heating up from just sitting around doing nothing.

You could try disabling the governor and let one like, setcpu do it? Before I went Incredikernel I set up a profile in setcpu that whenever my screen was off it wouldn't run any faster then 128MHz but when on was set for either on demand or performance. Using two governors at the same time causes lag I've found so you'd have to be running a rom that doesn't already have one (that you can see and change) built in
Yea, this is true. OC'ing I thought it was giving me speed, but I actually took the time to really see the speed on OC'ing and to me it dosent seem to change. Well maybe alittle bit, but still. But yea, so I just hit 1ghz and I just leave it there.
Pete's latest w/Yennob-Base2 kernel at 1ghz and its going good.

Personally, I find myself running into a wall with RAM more than with processor power. I really hope the next Nexus at least doubles it.

This. I'm really feeling the loss of RAM coming from a mytouch 4G. That extra 256MB really made a difference. Using juwe's RAM optimization script seems to help, though.
Ehm, how can Ram be a problem?
Android is managing it itself and can't run out of it, usually.

Things get killed that you don't want getting killed, and when it starts to run low things slow down considerably. It's not that something won't run, but it may run badly, or cause other apps to close that you were multitasking on, which is inconvenient.

How so? I normally get around 9-10 hours max with moderate use, also depending on the signal i get half the time.
I use netarchys latest bfs kernel with proton to undervolt all CPU frequencies to -20mv. And I have the CPU limited to 100-800mhz, with the on demand governer. With those 2 thing I get 15-16 hours everyday. I also usually let my batter get down to atleast 5% before charging.

Savage Zen/Tiamat kernel

On CM7 I dont have ondemand governor with the tiamat or savage. Only with stock CM7 kernel. What should I use instead?
Also does it take a while to notice improve me with these kernels?
Also those with awesome battery life on stock battery are you leaving wifi on? I get about half those times but I leave 3g on all the time.
I wish I could get through an 8 hour work day with 5hrs of screen on time on my battery.
Usually on my yoobao 3000mah I get 4.5hrs on screen time with no charging throughout the day lasts about 17hrs that way.
If I switch back to my stock battery I wouldnt be getting that would I?
CM7.1 nightly
yoobao 3000mah battery
tiamat 407 kernel. Everything under volted by 50mV but I do not think it is sticking.

i prefer the SavagedZen 2.2.1 kernel with savagedzen. but would suggest trying the smartass and interactiveX governors to see which one you and your phone prefer. some folks like the 3.06 version of Tiamat, you may want to ask folks in the tiamat thread about the diff between 4.07 and 3.06 (not positive on the version numbers).
i'd suggest running each for a couple days to see how it feels.
i use Tasker to activate my wifi when i arrive at work and at home...the rest of the time my wifi is off unless i turn it on.
the "5hrs of screen on time" may be an issue, the screen draws a lot of juice. perhaps if you verify your undervolting is sticking, used no widgets, do not use live wallpapers, set everything to sync once or twice a day you'd get further...but thats kinda no fun and i still don't think you'd get 5hrs.
i've had a light day on my phone...1.5hrs of screen on and i'm at 16hrs w/ 44% left. standard battery.
How can I verify the UV settings?
smartass is laggy
You guys should d/l System tuner. You can change your Governor with that app
Some guys swear by the SavagedZen kernel but it's reached the end of it's development life, the SavagedZen team is no longer supporting or updating the kernel and it hasn't been updated in almost 3 months. My personal experience with the kernel notwithstanding, I think that's reason enough to stick with Tiamat.
Turn brightness to 30 or 40%. Get a mugen 4500 mAh. Problem solved...your welcome.
Oh and there is ondemand in sz221. I am currently using tiamat 407 SBC conservative governor and my settings. No undervolt and working very nicely
I own a stock, gailio 2000mah, and siedio 3500. My 3500 never has a problem making a heavy day of use. I'm guessing that 4500 def wouldnt

you can use vipermod to set and verify your uv settings. there are other apps as well. but i find the script works well.
in CM7 you can set your governor and clock speed via:
menu -> settings -> Cyanogen Settings -> Performance -> CPU Settings
no 3rd party app is required. (unless you wish to use "profiles" like those available with SetCPU)
you may find interactiveX to be more responsive.
yes, SZ is not currently being developed and tiamat just released v407.
i may try the new tiamat kernel to see if it plays nice with my phone.
note: the new tiamat is based on 2.6.38.8 and SZ is based on 2.5.38.7.
thus far my EVO has shown a definite preference for SZ over Tiamat. /shrug
i always feel like i'm carrying around a pregnant EVO when i put on the 3500mh battery. LoL
My Evo also never ran tiamat well after 337 but 407 is running great
I avg five hours display on time. I have Deck's AOSP ROM and I turn off background data and sync twitter and email manually. I use Gemini App Manager to prevent apps from auto starting. I'm using a S-Z CFS kernel interactive x governor with SBC. I rely on 3g during my commute and wifi while at work and at home. I use the web, youtube and the xda app extensively. I don't think it is possible to have five hours screen on time using 3g only. Sprint's network is not that strong.

Safe Overclock Speeds?

I've read many threads where people say they have their G2 up around 1.5 and I'm just wondering what is considered a safe OC speed?
Some of the threads say there isn't much noticeable difference after 1.2, can any of you confirm this?
I'm on meXdroid right now and I've been keeping it at 1.2 but it gives me the option of going up to 1.516, so I'm wondering if there's any damage that might be done if I go with the max.

I'm running CM7.1 at a max of 1.4 without any problems. Not sure there is such a thing as completely "safe" when overclocking, but I also read about many who are at 1.5 or higher. I did notice a slight improvement going from 1.2 to 1.4 on my phone, but nothing substantial.
its safe to oc at 1.5 the thing is you wont be gaining a lot of performance but you will be draining more juice
After 1.2 the only thing you get is more battery consuccion.
The safe way is keeping the cpu ondemand or conservative between 245 - 1200.
If you want safe battery you can use setcpu and make 2 profiles one in screen off (powersave 245-368) screen on (ondemand 245-1200).
Note: for miui screen off profile have to be (245-768) because (245-368) cause delay in incoming calls.
And remember always the scale depends what kernel you use.
I using now pershoot 2.6.35.14
Is good with battery life so i recommended to you.
I was using ILWT kernel v1.5.1, is more better on battery life but i notice some problems went i use maps.
I hope that help you

Ive also looked into this quite a bit and most people say around 1200mhz is the sweet spot for battery and speed.
also overclocking depends on kernel

The OP is using meXdroidmod which has "tweaKr" script so no need for set CPU and he also has option to adjust voltages and many other tweaks. MeXdroidmod is awesome!
To the OP, just keep it at 1.2 . Like others have mentioned...just wasting juice if any higher.
HTC Vision(G2), meXdroidmod Ghost Chili AIO ROM/ICS CM7 theme.
I have mine at 1.6Ghz set on performance screen on, 368-768 ondemand screen off. I'm a medium/light user and will have around 20-30% left when i plug it in at night.
The amount you can overclock while still maintaining decent battery life really depends on if you're a light/medium/heavy user - because the charge is only being rapidly drained while the screen is on (if you have a sensible screen off profile set up). Light users can afford to run at high speeds on performance govenors, heavy users should run at lower speeds with conservative governors.
As for how safe overclocking is i'm not completely sure what the limits are, but there are people who run their G2's at 2Ghz and get no problems... the biggest danger is probably heat damage to the phone, but the battery will fail before you get to temperatures that will damage the phone so i wouldn't worry about that. The other concern is reducing the life of the cpu, however the longest you will have a phone is around 2 years, and an overclocked cpu will still last far longer than this.
Hope I helped answer your question, I am running Miui btw.
