Battery Life on CM7 RC2 - EVO 4G Q&A, Help & Troubleshooting

Is it normal to have poor battery life on RC2? If not, can someone help me diagnose the issue?

Are you experiencing fluctuating 3g/1x data signals? I am in the Seattle area and am thus getting worse battery life.

Both of you should try looking in spare parts for runaway apps/partial wake lock. Also keep your radios off when not in use. You can also try a new kernel, or upgrade to one of the latest nightlies.

What's the RC versions for?

He's on CM7,,,RC is for Release Candidate, as in this is what the final version COULD look like, with some minor tweaks...but there will be an RC3 cuz they now have hdmi working.

i'm in seattle area as well and i don't get fluctuating 3g/1x so that might be a phone issue there and might wanna try updating radios prl or pri
although earlier today i put my phone to sleep from a full charge with wifi bt and 3g off and picked it up 20 min later it was hot and battery was at 14%

Question's about myn's two point two RLS5??

Is there a way to get the front camera to work?
My battery is dropping fast, any suggestions?

Use pri/NV 1.77 instead of 1.9.

The front Camera should be working on RLS5. What hardware is your Evo? Maybe try a different kernel or something, but the front cam does work natively in RLS5
As for the battery, as jacoballen stated, I had better luck on pri 1.77 on Myn's rom. There are a million variable that can come into play when battery life is an issue however, and it could be a runaway app, your phone may not like the kernel you're using, it could be the PRI, you could have the 4g wake lock going on if you didn't reboot after shutting 4g off. Just a ton of things that can cause bad battery life. Just gotta rule them all out, one at a time.
Hmmmm. Mine isn't working either. Never looked at it when I flashed.
I was actually about to post about the battery drain myself. Ill try the PRI then go from there.

Thanks for the advice I will try everything because other than that this had been a fun ROM.

Use spare parts app to check partial wake usage. Anything that's more than a little sliver could be draining your battery.

Just an fyi, I just changed my kernel and it fixed my ffc not working.
Also downgraded the pri, we'll see if that helps the battery.

Best kernel for WiFi reception?

I'm I'm currently running destroyer v2 based on cm7 and wifi reception is terrible. Always dropping out on me. Been tempted to try the latest titanium kernel to see if that would help. But before I do that I thought I would get other peoples opinions on what to do..

Try out the new Tiamat Kernel. I've noticed a slight improvement in WIFI range, and a stellar improvement in battery life.

Tiamat 4.0.2 sbc+ all day

What's the latest version of Tiamat? Can someone possibly send me the link for the latest tiamat?

Also is it possible to just switch out just the kernel without losing the rom I have installed right now? Only way I know how is by starting all over and installing everything at once. Please help, thanks

I can say that godmode is not as good as tiamat its noticeably better

stroll over to the the development section and check them all out for yourself and yes you can switch out kernels. Also there is an app called kernel manager to check out kernels. One more thing its obvious you are not a chronic flasher like a lot of us so please remember nandroid and read up- As the saying goes here "Google is your Friend". Especially all the OP's of kernels and roms... hate to see you brick your device... Happy flashing

hmmm, can you prove this fact. i have aosp rom now and use my wifi while at home since it uses less battery than mobile data, but the wifi stays connected, full bars at all times im actually able to walk out to my truck and stay connected to my wifi where as before i rooted and was connected to wifi, i would lose wifi connection once i stepped out the door.

From a glaxay better than yours.
for me i think the signal is either the same or slightly worse, and the battery seems about the same so far, no significant difference.

Been using the new modem for the last two days thanks to team kang.
My download speeds havent improved. What has improved is the ping. on the old modem i was getting 860ms for ping but now its only 43ms. much better. I live in a major city and didnt expect the modem to improve the dl speeds.

For me. Signal is about the same and battery life sucks. I'm about 2 hours off the charger and I'm at 51%. I cleared bat stats through cwm after fully charging and waited till 100% again after reboot before unplugging. This is my 3rd cycle after changing to Whitehawk's KL1 and updating the baseband.

Are you on wifi? Or the Tmobile network? Try flashing a new kernel like fauxs. I'm getting great battery life.

[Q] WIFI signal VS New Radio Update

Hi Everyone,
I flashed my evo4g with evo-deck-1.3. My WIFI signal seems low. Does it help if I flash the new radio to improve my wifi signal? Does the wifi relate to the rom instead of radio?
Thanks

I've notice this as well on either cm7 stable or deck final 1.3. search Google and came across this thread. really love those two roms, hoping someone know a fix or hack to improve wifi.
Radios don't affect WiFi strength in any way..........

Also your probably coming from a sense rom on aosp it shows true data bars. For example 1bar on WiFi might be 3 on a sense rom

One of the files controls wifi just can't remember if its radio NV or pri but there is a hardware radio for wifi which needs firmware to run
Same here
Know that you mention it, happen the same when I flash the new radios, dont know what happen.
Evo deck stable 1.3
I use deck 1.3 (2.3.7) and I get wireless N signal at farther ranges then I ever did with stock...sense or even cm7... dunno about G tho

Do different modems affect battery life?

My question is do different modems affect our battery life differently or not really?

Yes they do from my experience. They also effect your signal strength.

I'm aware what a modem is and that it affects signal and strength lol. Just wanted to know if they have effect on battery life. Thanks for the response!
Sent from my SPH-D710 using XDA App
Signal strength directly affects battery life, so that'll be a yes.
I flashed my modem back to EG30 a couple days ago because before ever experimenting, I got the best data speeds on EG30 Modem. So far it has been the same way since I've flashed back to it. I've been getting good signal strength majority of where I go. But my battery drains a little faster than it did on EK02. EL29 Modem also gave me unacceptable drainage.

Im currently experimenting with all modems on Blazer ROM 3.9 Im not done testing at the moment but If I had to pick the best modem w/ respect to battery life right now it would be the EL13. Im in Chicago BTW

EL13 always gave me good signal. But my data speeds took major slow down hit. I might test it though. I am also running Blazer Rom v3.9
