I strongly suggest wiping. I was one ove the testers before he released the rom and i first didnt wipe and put it over the 1.0.2 and i was haveing alot of fc and things werent functioning rite. But wen i wiped everything 3xs its running like sea biscuit in the kentucky derby fo real! Deff a well put rom and vry very responsive. Like i posted a lil bit back the quadrant score was 1360-1400 rite off the bat aftr puttin the radio,wimax and the netarchy kernel 4.0.3a. My fps were 56 w a 3.96 st. Cant ask for any better results. Question for everyone. In what order do you guys wipe your phone?

I sill have a few issues. I cant dial *2 without the phone app crashing and my battery life isnt great (hopefully thatll be fixed with a full charge cycle). Also, is there a way of using the 4G button from sense in ADW?
[EVO 4G Android Development] mattsm:
Really depends on each case.

Generally the more undervolt your phone can handle, the better the battery life.

But I am seeing something different. My phone has the best battery life with with nothing less than the -100Mv. As for a major difference between the two, it will not be heavily noticeable. Hope that helps you.
[EVO 4G Android Development] VisedMonk:
The theory goes that the lower the undervolt your phone can handle, the better your battery life because each cpu frequency uses less power. So, if that theory holds, then -150 mV would give you better battery life than -100 mV or -50 mV. Some people say the undervolt doesn't help but actually hurts battery life because your cpu has to work longer and/or harder to complete the same tasks than it would if not for the undervolt, therefore actually using more battery.

I run the -100 mV script and I personally get better battery life for my normal usage (mostly email and text, few short phone calls) than without any undervolt. Although my phone can handle the -150 mV script, which some aren't able to do, I don't notice any improved battery life from the -100 mV script and encounter random reboots if I try to do too much with my phone within a few seconds of waking it up.

My advice is to start at the -50 mV, which is cooked into this rom and see what your battery life is. Place the -100 mV and -150 mV scripts on your sdcard, as well as the remove undervolt script, and play around with them over a few days. For example, before I settled on -100 mV, I tried all the scripts for a couple of days. I would flash a different one at night, charge my phone, and then run it for a couple of days to see how my phone performed. Hope this helps.

*EDIT* As Calk pointed out, the people who say undervolt causes your phone to work harder and therefore use more battery are probably referring to underclocking and therefore you shouldn't listen to them.
[EVO 4G Android Development] fgr:
Yup, it is the kernal, I switched to one of ziggy's I have and it is fast.

The script posted in the sd card thread does work though...

i did it once before on v1.6 and it did get stuck so titanium wasnt the problem. ill give it a try on this version and hopefully i can pinpoint the problem. if you have any more ideas please let me know. thanks again for the reply.
[EVO 4G Android Development] VisedMonk:
What version are your radio's, NV, and PRL? Have you updated them recently? Perhaps that is causing the problem because v1.6 + are based on 3.70, not 3.30. If you update your radios that could fix the problem. There's a link to the newest radio updates in the OP.
[EVO 4G Android Development] Calkulin:
Whoever said that OBVIOUSLY doesn't know what the hell they are talking about. Undervolting will ALWAYS give better battery life no matter what as you are using less power, now underclocking, which is what that person is talking about, might cause the CPU to take longer to complete a task as you are lowering the CPU speed but usually underclocking lowers the voltages also, so it's a trade-off
[EVO 4G Android Development] VisedMonk:
I agree with you, sir. I trust you and Ziggy. Neither of you have ever steered me wrong and have always been more than helpful. And that's why I undervolt - I figure neither of you would bother if it weren't true. I wish my phone was stable enough to handle the -150 mV.
[EVO 4G Android Development] polkadots:
So...who is going to compare Calk's ROM to a the AndroidCentral test?

[EVO 4G Android Development] gpz1100:
Thanks for the link.

I think the results are useful, but his test methodology is flawed.

What i've noticed (and I think this applies to the stock battery too to some extent), is after the green light is on, the battery still accepts more charge. See this link - http://img269.imageshack.us/img269/5889/graphmf.png -. Count 12 or 13 horizontal tick marks over. That's when the green light came on, but it still continued to charge for another 60-90 min. This is NOT with an SBC modified kernel either, just the regular evio (ziggy) kernel that came with 1.7.7. I consider the battery fully charged once the battery waveform reach what's in the last third of that graph. Note, every tick mark on there is 10 minutes.
[EVO 4G Android Development] polkadots:
Well, there can be some debate over how full his charge was, and if it was truly 100%...but I'd be curious to see how our Evos with the -100 or -150 stack up following the same method.

On a different note...it seems that with the -150 flashed that I quickly drop from 100 to 92 without any use at all. What's up with that? I didn't notice this with the -100...
[EVO 4G Android Development] VisedMonk:
I'll put Calk's rom up against it (flawed methodology and all) any day if I had an extended battery.

But this is what I've gotten today with my normal usage (almost entirely 3G, not Wi-Fi). Over 9.5 hours off the charger, just short of 2 hours of awake time:

Moved dalvik-cache to cache partition

How does this work if I enable davlik cache to sd card via spare parts. Does it interfere with this setting he already has enabled "Moved dalvik-cache to cache partition"

Thanks
[EVO 4G Android Development] merkk:
I had that behavior since day one - maybe sometimes it would stop at 95 or 94% - but it would always drop several percent within the first minutes or so of being disconnected after seemingly being fully charged.

Dont remember where but i thought i read on here somewhere that this is done on purpose by HTC as some sort of safety measure or something ?
[EVO 4G Android Development] polkadots:
I'm just curious how a stock battery would stack up...an extended...well, good Lord that'd last for weeks!

Hmm...that could be. But like I said, I swear I didn't notice this with the -100 undervolt. I could be wrong though.

I went back and looked at your posts to see what the problem was - did you try clearing the cache and dalvik cache in recovery? Any time my phone gets stuck at the white boot screen, that fixes it for me.
[EVO 4G Android Development] ro2themax:
thanks for your reply,

i wiped cache and dalvik cache multiple times before i flash a rom and/or install a kernel. That was the first thing i thought of also, but it still doesnt work. If you have any more ideas please let me know, thanks for your help.
[EVO 4G Android Development] VisedMonk:
Ok. Here's what I would do.

First, make sure you wiped the cache and dalvik before you flashed. If you did and it still doesn't work, then do this: backup whatever the last rom that worked for you was. Then get Calk's Format ALL zip (I can't het the link because I'm on my phone, but a quick google search should find it) and place that and v1.7.7 of this rom on your sdcard. Boot into recovery and wipe the cache and Dalvik cache and the factory reset. Then flash the format all zip and then the rom.

If that doesn't work then throw your phone into a lake and say you lost it...
[EVO 4G Android Development] ro2themax:
lol...i felt like tossing my phone into a wall then setting it on fire because im so frustrated with it...but im going to look for the format all zip...thanks for all your help, i really appreciate it.

re boots when charging

Few days ago i saw a few of us were having issues with random reboots while plugged in charging. I thought it was fixed when i flash the newest ziggy but that didnt help. Ive done all the undervolts, every ziggy i have. tried a few other kerns and nothing seems to help. it gets annoying while using your phone and it locks up and reboots. ive re flashed the rom, wiped everything 3 times, ran calks format all the undervolts and still have the problem. Just for grins i re flashed to another rom i really like but its from another dev. and it was normal. also for you saying that you get better battery life on the -150 thats bs. I got less then 5 with it and on the -100 i got about 7. the -50 i got 14+ twice. yes i did those with the embedded ziggy kern

any ideas would be cool.

Thanks :cool:
[EVO 4G Android Development] gpz1100:
Use units with your numbers. As they taught us in chem101, unitless numbers are useless.

As for your issue, not all processors respond well to undervolting.

[EVO 4G Android Development] sgt. slaughter:
Well had my first semi major issue here with the Evo. woke up this morning to find the phone stuck on the white HTC screen after charging all night with the deskclock running. I pulled the battery and tried to restart it but it kept getting stuck at the white screen. Tried to NAND backup but got the run nandroid-mobile.sh via adb message in there. tried wiping cache and davlik, and also flashing a different kernel and none got it past the white screen no matter how long it sat there.

I really want to pull a backup of at least my texts before doing a full wipe and tried to mount in adb but somehow I couldn't get it to even mount which i found odd. though im probably doing something silly stupid here messing that up. I just want to pull the "/data/data/com.android.providers.telephony/databases/mmssms.db" for my messages.

When in this situation and i want to mount via adb do i boot into recovery or fastboot or what? also anything particular i should do besides moving to the android sdk folder and typing the adb remount command to get it to mount? When in recovery i get "remount failed: Invalid argument" as the response in the cmd window.

EDIT:

nvm DUH cant mount in recovery b/c system isn't mounted yet. ended up booting up and letting it sit at the white screen and am currently pulling the /system to do the backup

Edit: well that didn't pull what i wanted and it seems there is nothing in the data least when i do adb pull data i pull zero files

Edit3:

well seems there somehow became a problem of the /data folder in the phone. in Amon recover the log shows the following when i try to do a back up: "mounting /dev/block/mtdblock6 on /data failed: Not a directory Error mounting data read-only umount: can't umount /data"

any advice on this? kinda odd it just happened outa the blue here.

even tried flashing the rom again and got stuck at the screen so im at a loss now.
[EVO 4G Android Development] VisedMonk:
It's not just an HTC safety design, but a Li-ion safety design. Leaving out all the technical stuff, our batteries "drop" quickly from 100% because they aren't really at 100% but somewhere in the 90's. IMAO, the 90% to 5% discharge rate of your phone battery is far, far, FAR more important that the "100%" to 90% discharge rate. So you really shouldn't pay attention to that initial drop because it's just your battery doing its thing. That's just the way it is, although the SBC kernels use battery code to trickle charge the battery. There's debate as to whether those are safe and there have been some reports of damaged phones and destroyed batteries from their use, although I'm not aware of any objective evidence that SBC was the issue. I don't use them, but lot's of people do. If you want to use them, make an informed decision and then don't blame anyone but yourself if you f*ck up your phone.

Calkulin this is by far the best rom I have ever used thank you do much.

There are some very small issues. That I'm hoping somebody can help me with. For instance when a call comes in and I'm on ther other line. It doesn't beep our make a noise to let me know when someone is calling. It might be my head set I have a blue ant q2

When a call comes in it takes a little longer then usual for the screen to light up.

The phone had only restarted on me once. I'm using the volt -50 might try the -100

Any suggestions thank you

thanks for the response.

I actually created one in the dev section itself but no responses this morning and me being impatient i just decided to wipe the data folder and reflash the rom all over again.

really odd b/c before wiping the data folder i couldn't pull it via adb at all and reflashing calks rom never resulted in it working. hell i even tried flashing ava's but it gave me an error mounting data in RA recovery. Couldn't do any backups in recovery nor could i even do a restore in recovery b/c of the error.

oh well really odd, and i have absolutely no idea why it happened or what could of caused it. just gonna have to restore what i had backed up from Tibackup which unfortunately is a week old, but oh well, least its booting up now.

By any chance do you have an Airave 3G Microcell from Sprint? This same thing happens to me when I am at home within range of my Airave and I miss calls due to no Call Waiting Beep.

Hi all. FWIW, I placed my EVO w/ the latest version of Calk's rom, stock battery, Ziggy's 15 Jan 11 CFS kernel, and the -100 mV script through the same test as the Android Central ("AC") seidio 3500 mah battery review, flawed methodology and all. I tried to replicate the test as best I could, the only big difference is that I had to run my test on 3G rather than Wi-Fi (no Wi-Fi at work). I don't know how that would effect things, but I imagine it would make my battery discharge faster since Wi-Fi is more efficient than 3G.

Here are my results:

--Off charger at 9:46 a.m.

--15% alarm at 1:01 p.m.

--Shut down at 1:39 p.m.

--Total of 3h 53 min off charger

If you recall, the AC reviewer got 3 h 4 mins off the charger w/ the stock battery, so my test of Calk's rom and Ziggy's latest kernel and the -100 mV script got me 49 mins more than the AC review.

Yet another reason Calk's rom is the best...
[EVO 4G Android Development] REVREN:
Hey calkulin,I like to say that your roms are infact the best sense rom for the evo,in my opinion.I only bless my evo with your gooddies,but with the latest rom 1.7.7.I was getting a dead screen when the phone was in 4g after around 30 to 40 minutes sitting,when hitting the power button to awake the phone it would not awake no response,so i had to take the battery out and reboot,so after many wipes and flashing,i found the cause of the dead screen to be the ziggy kernal that i was installing (ztest-evo-120410).so i tried the (ztest-evo-bfs-121910)and the phone is working great now no more dead screen and the battery life with running the set cpu at 1113mhz max and 245mhz min is amazing adn phone is very snappy,just wanted to say thanks for all the hard work with your roms i appreciate!peace!

Are you going to do the same test with the seidio battery too?

I can't recall, but does the android central article specify which rom the test uses? I just looked at the article and can't find it. Again, just another reason why I think it's flawed. Look at any video card or cpu benchmark, full disclosure of all pertinent hardware/software version details usually prefaces the benchmark results.

I just wanted to take a moment and thank Calkulin and all of the other contributors to this ROM. EViO 2 has made for the best Android experience thus far.

I took my Evo off the charger around 8:30am yesterday and used it during the day the same way I usually do. This meant about 20 minutes of voice use, some periodic text messaging and Facebook browsing and around 5 minutes of web browsing. When I got home from work at 6PM, I still had 85% battery life left which was excellent IMO. After getting settled in, I realized my Sprint Airave and DSL were not connected (due to an area-wide Telco outage). I immediately turned on Wireless Tether, placed my phone by the window and stayed connected via 3G for about 4 hours. When I was done I still had 22% battery left. I was absolutely amazed at how long I ran it with less than anticipated drain on the battery. The -150 undervolt works great on my 003 Evo with a stock battery. I look forward to seeing what the next update brings. Thanks again!

Unfortunately no. Sprint told me it was a known issue when I called in the middle of November. Since it hasn't been fixed yet, I get the impression that they are not in a hurry to fix it :(. I have a feeling they will have to update the firmware soon as they are now charging customers to buy the 3G Airave and agree to a contract. I, like most others received it for free due to the weak signal in my home, so I don't mind putting up with some issues with it from time to time. If I had paid for my Airave, it would be another story.

Browser reboot

Any of you notice a reboot if you immediately try to use the browser after the phone's booted. If I access the browser right after the 3g icon has appear, i get the bar to move over about 1/2", then it stalls and shortly there after the phone reboots.

If I let it boot up, wait ~30 seconds then try to access the browser, all is fine. I have the -100mV script installed, but get same results with the 50mV too, so I don't think it's a cpu voltage issue.
