I always drain mine completely after flashing. The only way you phone will know what is 100% and 0% is to drain and recharge uninterupted til full. That is how your battery is calibrated :D
[Sprint HTC EVO 4G LTE] Nygel:
99% of minor issue will be from dirty flashes. Verify the MD5 at all times to be on the safe side. On first load up you will notice that the battery will drain kinda fast because the apps will be working on permissions etc. What works for me could be a little tedious for others but it works.

1. download the rom

2. verify MD5 (MD5 checker.......its free)

3. perform a factory reset, If coming from another mean rom of the same base

4. Install rom zip file (yes the rom will wipe dalvik and cache for you)

5. after flash power off and power back on in approx 30 seconds.

6. once to lock screen let it sit there for a couple of minutes

7. setup normal user accounts, google, facebook, twitter...etc

8. let all my app return for playstore, because I dont use T-backup

9. Once thats complete i do a reboot.

10. after reboot then i setup my screens and sync all possible apps that needs to sync, and update sprint TV, basketball, football etc.

11. then I peform a profile update and PRL

then your device should be good to go. I keep dirty up dates to a minimum

hope this give somebody an idea and insight. After this if I have any issue then I can say it will possibly be ROM related.

There's no point in recalibrating the battery. What you do with that app has no effect on your battery life.

I never calibrate and never have any issues with battery problems, all it is, is the kernel sinking in to the system

hey if i flash one of the zips in the mean rom folder rite after i flash the rom is that ok?? or should i flash the rom set it up then go back into recovery and flash them???
[Sprint HTC EVO 4G LTE] CannibalAngel:
If you are that concerned with battery life you probably shouldn't be overclocking. There are going to be trade-offs when overclocking or going for long battery life. Overclocking will always decrease your battery life. There is no way around that. I am overclocked to 1.7 and have pretty decent battery life. I should also add that battery life is never really a concern for me because most of the time I have a way to charge my phone. Either by USB at work, Car charger in the car, or wall charger at home. If I think I may run out of battery before I get a chance to charge it again, I make sure It has enough juice or I stop using the phone.

And no, under-volting does nothing to improve battery life.

after rooting last night I'm S-off and flashed this ROM and noticed Wifi Tether was giving me errors saying I'm not rooted. I installed Root Checker and it also says I'm not rooted. How is this possible? what's my next step?

Love the Rom and on version 2.9, but add me to the battery problem list. I went to bed last night at 33% or so and woke up 7 hours later to a dead phone. During the day I've been able to drain it 50% in 2 hours.
[Sprint HTC EVO 4G LTE] schmeggy929:
Are you using a custom kernel?
[Sprint HTC EVO 4G LTE] steamanger:
I drained mine completely last night. No problems this morning. I'm on a clean install of 3.0 with oc @ 1.8
[Sprint HTC EVO 4G LTE] Kilokk:
Try updating SuperUser binaries and actually make sure SuperUser is installed :good:
[Sprint HTC EVO 4G LTE] youngbasedgod:
I must be doing something terribly wrong. For all those who oc'd to 1.7 and still report great battery life, how exactly are you setting yours up? Do you just set it to 7 in root explorer, reboot and that's it, you're golden?

I completely drained mine last night and recharged it over night because I heard in this thread that that method yields great battery life, yet I woke up this morning and after 1h 7min of use, i'm already down to 82% battery life. Jeez.

[Sprint HTC EVO 4G LTE] njfoses:
My phone does not agree with the oc on v3.0 at all. On v2.5 i was able to run #7 or #8 with the oc script with no issues. Now i cant run either without bootloops, artifacts, apps crashing etc. I have played with the voltage settings and still no luck. Im forgetting about oc until htc gets off their behind and posts current source so we can get some current custom kernel's. V3.0 is running smooth thus far though.

People say the evo lte has great battery life. I am only assuming that is coming from the other evos lines. I came from the droid x and that phone batter after 2 years still out performs the evo lte battery eather I have a phone with just a bad battery or I just dont see the difference do to not coming from a previous evo

Not getting great life either. I just flashed the overclock off file this morning. I have lost over 12% within the hour of straight use. Can someone share what they did to get better battery life? Power save feature is on as well.

Also, just started this morning... My received text messages are dated/timed exactly 1 hour behind. But outgoing is fine. Can someone help me?

Downloaded to my phone from android file host without issue. Did it 3 times just to he sure. MD5 matches all 3 times. 1200+ downloads according to the website.

Dev-Host starts out slow but seems to pickup speed as it progresses. Don't know why.
[Sprint HTC EVO 4G LTE] indiscriminant:
That IS good battery life, if you used your phone constantly with the screen on for an hour and went down 12% that means you are going to get over 8 hours of constant use on your phone if you used it the entire time.

Yes, you need to update twrp to 2.2.1. You can use goomanager to get it or go to the teamwin website and download it directly. Once the rom size grew above 600mb with the addition of googlenow the older versions of twrp seem to have difficulty installing.

[Sprint HTC EVO 4G LTE] buzzwyzr:
Been covered multiple times in this thread...as recently as on this same.page a few posts above yours.

If you're using TWRP recovery...and on version 2.1.8...you MUST upgrade to 2.2.1 in order to flash any MeanROM 2.7 or higher.

Nope, I tried again last night and my phone went from 99% to 80% in about 7 hours and 15min. Screen was off pretty much whole time ans according to the better battery stats, the phone was in deep sleep for almost 6 1/2 hours of that time.

Does this sound wrong to anyone else? Or does the phone normally drain this much when doing absolutely nothing?

[Sprint HTC EVO 4G LTE] seewhyphotos:
MeanROM 3.0 is working smooth and solid for me!

I've been running this for a couple of days now, and have only been with 2.9 and now 3.0.

I really like how smooth my EVO LTE runs now. Here are my settings that I am using out of init.qcom.post_boot.sh:

PERFORMANCE_OR_BATTERY="BATTERY"

OVERCLOCK=8

SD_READ_AHEAD="128"

VOLTAGE="UNDER"

FAST_CHARGE="OFF"

This seems to give me great performance, and solid battery life.

When I run System Info, and watch the CPU stats, you can watch the cores working. You will see that they offline, online, run at minimum, jump up to max cpu (In my case, that is 1.728GHz), then settle down. I run the onDemand profile so that when it's quiet, the system slows down and saves on battery.

This setup is working for me and I'm very happy with it. Here are some screens to support what I'm saying:
[Sprint HTC EVO 4G LTE] mikeyxda:
Anyone who sees the second core offline: you've flashed a tweak, mod, or CPU tool that broke the dual core or you used an OC method other than the one posted in post 2 of this thread. The ROM as installed will always have both cored online with the screen on and one core online with the screen off.

Mike
[Sprint HTC EVO 4G LTE] Kilokk:
Yes, and it works GREAT!! You will most definitely reap rewards for using this. I personally don't care for Sense at all, especially since there are tons of third party apps that are way better. Just download the zip file, choose if you want Sense based or No-Sense<< awesome, check the thread for the instructions and choose if you want to add more or not to the remove script. There was one edit that I made right away before installing and that was to keep the themes intact, i.e.. aluminum.apk, matte.apk etc, because if you use RacerOfAlls deSensed ICS theme you need to keep those along with the other items Patrics83 pointed out to me on this thread (One X) Post#863 http://xdaforums.com/showthread.php?t=1832162

Why would you change the default sd_read_ahead? I thought the bigger the number the better? I usually used sd booster and set to 500 but i see my phone default number is 2000 or something like that. Any reason why? and what exactly does it do?

I rooted my evo lte. s-off and installed the latest Mean ROM. today I noticed I had lost root. when I open SuperSU I get this error message, "There is no SU binary installed, and SuperSU cannot install it. This is a problem!" How do I fix this problem? I downloaded the .zip from the superuser thread but apparently he no longer supports it? and tried flashing it in TWRP but it failed, everytime. How do I update the binaries? Soon as I open SuperSU it gives me that error message and no matter what button I press it just closes.
[Sprint HTC EVO 4G LTE] seewhyphotos:
From what I've read, the SD Read_ahead is impacted by the speed of your SD Card. I've played around with it and booted it in a few different ways, and that number seems to give me the best performance on MY phone. I believe that the combination of Vendors/Speed and Sizes will react differently to different settings. I used to use sd booster, and experienced the same things.. different cards used different settings.

I'm no expert, but that is what worked for me...

Just an FYI. I haven't installed any tweaks/mods, I've only flashed this ROM and nothing else. I OC'd by changing the line to OVERCLOCK="8", saved the file and rebooted the phone. Went into System Tuner and it would never show the 2nd core as being online, ever.

Anyway, I did a dirty install to 3.0 and at first it showed I was at max 1809 but I could only get 1500 out of it. What I did is I went into system tweaks and cpu and my second cpu was off I maxed them both to 1809, turned the phone off for 5 minutes, turned it back on and now it shows the correct mhz.
