Running Shubcraft 1.5 rebuild by warrenb v1.2a with ChuckyRom and Radio 2.12.50.02.2

My battery temp is always running HIGH. I mean its around 96*F with me just messing around, not running any heavy apps, not browsing, just playing with settings. Have my screen at 25% brightness, setcpu set just as detailed in the first post. Have conservative scaling set, but for some reason, most of the time the processor is running at full out 998.

Is this why the battery is so hot? And Im sure it being hot makes it drain a little faster too.

Arg this is frustrating. Android on the HD2 would be perfect in my opinion, if battery issues could be solved.

sorry , when u say task killer, are u refering to advance task killer?
[HD2 Android Q&A, Help & Troubleshooting and Genera] vcyeunghk:
Hi.

I just wanna ask what number should I input in Down Threshold? I can't just put 0 on it as it will automatically generate a number which must be lower than Up Threshold.

"# Up Threshold - Defines a percentage from 1% to 100%. When the CPU load reaches this point, the governor will scale the CPU up."

"# Down Threshold (conservative only) - Defines a percentage from 1% to 100%. When the CPU load reaches this point, the governor will scale the CPU down."

For my own experence, if I set 50% Up Threshold, the system will put 30% in Down Threshold. So is it means that when CPU hits 30% and it will underclocking? How can the CPU can reach 50% usage to scale up but underclocking when it reaches 30%?

Sorry for my poor english and misunderstanding if something is wrong.

Hi

Have a question

When i'm changing the Scaling to "ondemand" i'v noticed that it automatically changes to "powersave" when i'm using the phone and it slows the device considerable..

is there an explanation for that?

thanks

If you are using darkstones FroyoStone V2, don't use setcpu, it's already in the rom.

You will only get 245mhz and a lot of lag with setcpu. I have been using my phone for daily use since V2 came out and I'm getting many many hours of usage without setcpu and without any "task killers", almost as good battery usage as in WM.

I have tried the set cpu twice and it crashed my android (2.2 froyo) both times, but before doing that, it saved some battery life for me. this time I uninstalled the task killer app and i have seen some noticeable changes in battery life and responsiveness of the phone. but I have a problem now. for some reason my fm radio is not working. even if I restart the app, it won't play. i guess the app is running in the background somehow even if i kill the background tasks, because when i press the volume buttons on the side of the phone, it shows me the media volume change, not the ringtone volume change. Does anyone have any idea how i can fix that?
[HD2 Android Q&A, Help & Troubleshooting and Genera] Voffchik:
Oooooh...got it...

anyway the battery on darkstones FroyoStone V2 with moderate/heavy use died after 1.5 hr it's just killed the whole experience for me...

so i'v changed to mdeejay Froyo Sense v. 2.0 battery life improved considerable but other stuff, like BT are not working so i'm thinking on going back to darkstone..

did u do any changes except the task killer??

Turned off Background data in sync settings. And I try to stay away from apps that doesn't use push. And also...I calibrated my battery, it's worth a try:

1) Turn your device ON and Charge the device for 8 hours or more

2) Unplug the device and Turn the phone OFF and charge for 1 hour

3) Unplug the device Turn ON wait 2 minutes and Turn OFF and charge for another hour.

"Your battery life should almost double, we have tested this on our devices and other agents have seen a major difference as well"

You only need to do this once.

This calibration was sent from HTC by mail to a user here at XDA using the EVO.

wats the big deal about this solution? You keep charging it all the time, then any phone is bound to work!

I have been using SetCPU configuration and have been able to make battery last a day. Even while charging, it shows up 100% full battery and stays 100% for long.

Getting about 8mA in standby, around 3% to 4% drop per hour in standby, which is decent!

I was referring to woffchiks problem.

SetCPU and darkstones froyostone v2 don't go hand in hand. And some might wanna use their phones, not just keeping them in the pocket and brag about mA here and there.

[HD2 Android Q&A, Help & Troubleshooting and Genera] hastarin:
The kernel you're using has probably been built with "redundant" frequencies removed. Ie if two frequencies use the same voltage level only the higher frequency is made available.

I've currently got mine building so SetCPU detects the extra frequencies but when you set them it ignores you and goes to the highest frequency for a matching voltage.

I'm not sure which approach is better to be honest.

Hi, I have tried a few WM ROMS and found that the more the WM ROM has in it (IE not a stripped out for Android ROM) the better Android works. Hastarins 7.6 Kernal is excellent for Battery life and the tip about SetCPU is gold dust.

Personally I have found that conservative use of Wifi, SetCpu and Hastarins 7.6 with Radio 2.14.50 has given me pretty much stock battery life on my HD2 - I still have to charge every night but I don't have to charge when I get home from work and TBH I use my phone a lot more now that it actually does stuff :D.

2 Caveats - first I have not tried Radio 2.15.50 and second I am using MDeejays rEVOlution series - battery life gets better with each release but I put this down to the ministrations of Hastarin rather than MDeejay. I could be wrong.
[HD2 Android Q&A, Help & Troubleshooting and Genera] reocej:
Try this for better Android battery performance!

Tried different techniques to get better battery and found that even on the same build with exact same setup would give varying results. Here's my setup that I would like others to try and post their results. SetCpu with screen off profile set to 245min/max 100 priority and whatever main profile you like; but use conservative preferably or interactive for best battery performance. Any task killer that auto kills all tasks with screen off (be sure to add SetCPU to ignore list). And here is the most important step, use an auto android booting app with minimum boot time setting. I have been doing some experiments with this and found that if you boot into Android as soon as possible, it seems to give better battery performance as opposed to playing around in WM then booting Android. Have tried this with several WM/Android combos. For the first time ever I'm able to get comparable battery performance out of Android as WM. I'm running a bare bones WM (but should work with and WM rom) and using Exceller Multiple Build Loader app set to 3 secs. Even running several sense builds I was able to achieve 3-7 mA draw during standby according to current widget. Took my phone off the charger at about 6:30 a.m. and it is now 11:15 and I still have 25% battery left after pretty heavy usage on standard battery. This is as good or better than what I usually get from WM! Hope this helps.
[HD2 Android Q&A, Help & Troubleshooting and Genera] xarejay28x:
Hey reocej

i dont want to be a push over but im trying to achieve the same battery life and i have been messing with settings for awhile and putting different combos of WM + Android together im only able to get as low as 20-50 mA on standby. would you be able to post your exact versions of build of Roms? i know you said you tried various builds but i would like to start of with what is most stable for you and work from there.

and i will try those stepps your suggested. thanks!
[HD2 Android Q&A, Help & Troubleshooting and Genera] reocej:
Sure. Right now I'm running VBNROM Reloaded w/2.15 radio-> Rom Link->http://www.vbnfiles.com/xda/vbn/ROM/CLARITY/Windroid/VBNDroid-Reloaded2-21913-Oct08.rar For Android I'm testing several of Mdeejay's latest sense builds and all give about the same battery performance. Also have an install of JDMS 1.3 on my card and I use Exceller's boot app set to auto boot within 3 secs. I think the main key is to not let WM boot fully and/or disable sense altogether. If I change builds in the auto boot app, I reboot my phone and let Excellers app boot Android for me. I'm averaging around 5-6 mA in standby (around 2-3 mA in airplane mode) which is very good for any sense build! Like I said, use a auto task killer and only allow SetCPU and Current Widget on the ignore list. I personally use the Task Manager from the Adao Team as it is very light at only 87 kb. Don't need anything fancy, just something to kill all tasks at screen off. Hope this helps.

Also as a side note, I don't live in a 3g area and coverage can affect your outcome. If you live in spotty coverage, your phone will consume more battery trying to find/keep a signal.

[HD2 Android Q&A, Help & Troubleshooting and Genera] reocej:
I did none of that and I consistently get 4-8 mA drain in standby with WiFi, GPS, Sync and Bluetooth all enabled! Not saying it doesn't help, just saying I don't think it's necessary. I have 6 different android builds on my card and get pretty much the same results with all builds. If I let WM/Sense boot fully I get mega battery drain. If I let Exceller's app boot android before WM/Sense fully boots battery drain is gone. I don't live in 3g coverage so I guess if you do use 3g you will naturally experience a little more drain. Also, I've tested this with several different WM roms and the results are similar. I'm no dev/expert but after testing I would conclude that WM/Sense is the likely culprit for the battery drain in android.

My simple guide to getting 3mA drain in standby

I have two flavors of Android that are currently my favorites. Great performance, no freezes fully functional and acceptable as an alternate for everyday use. One is phiredrop's Skinny EVO v1.5 and the other is mDeejays Sense rEVOlution v2.3. Both are based on the EVO ROM and both are Sense builds. After a lot of experimentation I have found battery life to be excellent with the following procedure.

Always boot your Android using Excellers Android loader. Boot up into Windows Mobile. Once it is settled in tap on the Exceller Loader icon but do not launch Android at this point, instead hit your home hardkey to light up the hardkeys then immediately tap on the Exceller Loader icon again and load your choice of build before the hardkey lights go off.

Once Android is fully loaded turn off screen auto rotation and disable auto brightness in settings. Then set the brightness level one notch below what is default. Do not use SetCPU nor any task killers whether they be manual or automatic. These are not needed for great battery life and can be detrimental to your performance and battery life rather than beneficial. Go to the Market and download and install CurrentWidget and set it to show on your main screen. Turn off GPS, Wifi, and bluetooth since you do not use them full time anyway.

If you spend most of your day inside of a factory as I do, or any other place where carrier signal is not good, get an airplane mode widget to put your device into Airplane Mode whenever the signal is spotty. If you have a signal fulltime then the airplane mode is not necessary as I have found the drain on the battery to be exactly the same with it off or on when I have a good signal.

Do all of the above then hit the hard end key to put your phone in standby. Let it set a couple of minutes then hit the key again to light it up, unlock it and take a look at the mA reading on your current widget. I think you will be pleasantly surprised at the results.

By the way, when at home with good signal and Wifi turned on, this setup for these two builds draws only 4mA in standby.

I also set the 11.02.miui.english build up this exact same way and it was only drawing 3mA in standby also. Give it a try and let me know your results for your build. I would like some info specifically on the non-EVO builds, as well as Sense and non-Sense builds for this method.

One more thing to consider, I am NOT using hot reboot to get these readings. These are readings that I get on each and every boot with the method explained above. Hot Reboot is a handy tool to have installed if you have some crazy app that wants to drag your device down and won't turn loose, but it is totally unnecessary for good battery life.

[HD2 Android Q&A, Help & Troubleshooting and Genera] hitekredneck:
So I guess you have figured out by now that GPS uses some juice when it is enabled. That is only natural, GPS is a pretty big battery hog and should not be left enabled all of the time, only when you need it. I suggest a car charger connection at all times while navigating. Not very helpful advice if you are using the GPS while walking though. You may want to invest in a spare battery. :)

Just got the SetCPU app on my HD2 a day or 2 ago. tried a lot of the suggestions that were said in the forums. Here's a small question, I'm running CurrentWidget right now to monitor my battery consumption. I read other posts that some people got around 8-10mA when their phones were on standby. I'm getting 56-60mA on standby at the moment. I am not running any wireless services, 3G is also turned off. I am however, not on airplane mode though, but according to what I read, i should be around the 8-12mA region right now. Any ideas?

I'm using ChuckyROM for my Windows (Sense disabled and used BsB Tweak before loading Android); Android system is on the Froyostone build with the default Kernel. Also have a 4Gb Class 4 memory card plugged in. Running the SetCPU with recommended setting from the forums and also use Advanced Task Killer just kill all apps and I kill it with the other apps too (except for SetCPU)

tia

EDIT: Found out how what's happening to my phone after reading a lot more. It has something to do with the Kernel. For those who are experiencing the same amounts of battery drain (56-62mA at standby), update your Kernel. I used hasterin's 8.2 Kernel and it worked wonders on my phone. I'm running at 6mA at standby right now.

Thanks hasterin!

i must apologize for that post i do not get 22 + "PLUS" hrs if i was on it constantly on WIFI or playing games through the whole day. i average around 10-14 hrs of HEAVY usage. nevertheless i do get a incredible battery life after doing reocej's suggest and i did get a 300% improvement.

a typical day i take off my phone from charge 100%

*i play games prob for an average of 3hrs a day.

*i send/receive Texts on an average total of 30 text messages

*use data connection ave. 2hrs (sync email, updates, etc)

*talk for 1hr average.

*wifi 30mins (just to DL apps and videos)

total hrs = 6 - 8 hrs of usage total with at least 40% lefts. and in idle i lose 1% every 1.5hrs. so total i get a very good battery life compared to my old set up.

so please dont think that i use wifi + data+ text + gaming for 22hrs the whole time. i just wanted to put it out there that one full 100% battery can last me a whole day. look at my signature for my setups
