Hi, can anyone tell me the best lite ROM for battery life with the start button in bottom left ?
I love all the sense stuff but can live with the terrible battery life.
As long as i have active sync, i will try it.
many thanks
Now trying an older TAEL version
hey all.
im off to glasto soon and was gonna load up the hero with a nice long battery life rom - anyone know a good one?
also, is there somewhere with a general list of stuff to make it last longer - i guess a 1 press widget to stop all data would be ideal? anything else? an auto task killer maybe?
i will be able to charge it occasionally at a mates caravan but i'd like to do that as little as pos.
thanks for reading
I'm still using 42turkey's rooted repack of the Taiwan official GSM Hero 2.1.
http://forum.xda-developers.com/showthread.php?t=694786
Everything works on it, and since it has Sense UI, there is a widget for Mobile data on/off.
Battery life seems great on this rom as well.
The ONLY thing that does not work well is the handwriting input method, as it is Chinese (the rest of the phone can be set to 100% all english though).
Lucky bugger!!!...
If I was you i'd flash MCR3.2. The most stable 1.5 ROM. Then underclock the standby.
I've heard people recommend Juice Defender but haven't tried it myself.

I would reccomend Cronos Droid 1.7.1 and then set the clock speed to standard 528Mhz (518Mhz) set the low freq at 246Mhz I think it is and the mess a little around in SetCPU like setting the sleep freq at max 480MHz and underclocking it when the battery runs low Last of all Cronos Droid is the best ROM performance wise, stable wise (if you can say that) and in my expiriences also battery wise and It's just the best if you aren't trying to find a ROM you can theme etc.
just buy those cheap portable batt chargers that use a single AA batt and u'll never run out of power as long as u can buy AA batts. It won't charge your phone very much but it will certainly keep the phone at a constant level.
awesome cheers all - im having a look at the ones detailed, will definatelylook into the overclocking thing.
and the aa battery thing....i think i've got one of them already for my mp3 player! never made the link that the phone could use it too. super!
cheers again, off to pack
There's a ninpo kernel on Villain10.3, which has some optional battery optimisations. I can't really gauge it against other ROMs as I haven't tested it like that, but adding autokiller and keeping the phone underclocked to the stock speed via SetCPU. I also run mine at 19MHz in sleep mode, but be aware not all heros are compatible with this, and yours might not wake up properly at 19MHz. Try it and see
If you're running Android on your HD2, then battery will last about half of what it lasted with WM. If you take a Desire device, its battery life will be at least double than a HD2 running Android (proving that it's not a fault with Android itself).
When the question is raised of why Android kills the HD2 battery so fast, the usual answer is: "Android for HD2 is still in its infancy stages".
The question is, do anyone has any clue why in this "infancy stages", battery performance is so poor ?, I mean, if you want to solve a problem, you first need to understand what causes the problem, and I don't think anyone understands why battery life is so poor, so why should we assume there will be any progress in this regard in future builds ?
I do believe that developers will probably be able to activate every feature of the HD2, simply because we understand why some features don't work now (for example: maybe we don't have an appropriate driver). Battery performance, on the other hand, seems to be a much more mystical feature, nobody understand exactly why the performance is poor, or what is needed to be done to improve it...

Because it runs off the SD card

What ???, that's the only (or even main) reason ???, the power requirments of the SD card are so much greater than that of the internal storage ?
Many people are reporting poor battery performance even in standby. Is the SD card active in standby too ?
try juice defender it turns off data when the screen is off.

Thanks for the tip, but you are not answering my question. In WM, data is not off when the screen is off, yet battery performance is good. With the Desire device, data too is not off when the screen is off, and battery performance is good too.

Actually Mystik610 already told you the problem. Yes, running Android from the SD card is the problem with battery performance.

Is the system running in standby? Obviously that it is, so the SD card is active also in standby. Equation solved.
Form what I understand it's because cpu scaling isn't fully functional yet... That's why the bottom of the device gets so hot when in use with android. That, along with the SD card and data (witch isn't 100% optimized yet) is why.
these settings worked for me in improving battery life

DisablePowerManagement=0
HKLM\Comm\PPTP1\Params

now with froyostone v1 I lose in standby around 1%/hour...in WM I lose 0.5%/hour
with setcpu set correctly (+the 925mV kernel) and those power management registry tweaks I'm able to do 2 and a half days with my phone, including usage like a few calls, a bit of browsing every day, about 4h of music and downloading mails four times a day.
Thats pretty impressive for me, don't remember getting much more or even more in WinMo.
I could say that SD card is not the only reason. I used Android-based devices (Liquid and Desire) for a while and I can say that android has slight problems with power management itself.
SD card !!!!!!!!

I was under the impression that in standby, the parts of the system still active, run from memory (RAM), and not storage.
I setup 248 only when standby

Something here doesn't make sense. If the main (and surely if only) reason for poor battery performance is because the system works from the SD Card, then why people offer SetCPU as a solution ?, if SetCPU can solve even part of the problem, it means that Android CPU scaling abilities are not working correctly with the HD2 builds. Am I wrong ?
Do people with the Desire device also get the same boost in battery performance after using SetCPU, as the people with the HD2 device ?
I've not noticed any difference in battery consumption using Android over WM.
Chucky Droid ROM
Radio 2.10.50.26
Mattc Leo + Froyo w/sense 1.5b
Great work by the way guys!

I used to get a day and a half in WM, now I get barely half a day with Android.
2 and half days? thats crazy. Can you send your setcpu setting? Even on airplane mode over night i'm losing 40-50%, no matter what i do.

I can confirm that SetCpu is vital for the Acer Liquid E. My girlfriend has one and I had to flash Liquid Community Rom with SetCpu due to power consumption.

You should try the tip posted in the other thread
http://forum.xda-developers.com/showpost.php?p=7764579&postcount=11
SD cards vary in class and power consumption. Get and try a class 2 card and you will see the difference. The latest cards are power hungry even in standby. I asked this question of Sandisk and I was told that the info is only available to devs!!!
It causes the problem with Winnow usage as well especially when you install any apps to the higher class of card.
Using a class two I get a day with heavy usage. Right now after 8 hours I have 60% left.

so, we may assume that if we nand flash android rom we can get better battery and performance, sorry for not reading lately this forum but is there flashable android rom for ANY ex-winmobile htc device and how this compares in battery performance with android roms running using haret.exe?
Hello all,
I have a question for you all:
I have flashed a new rom today and have decided to NOT activate Google Now, and (after a few hours only), I seem to see a much better battery use?
Is it possible that this app, being monitoring so much all the time hoggs the battery quite a lot?
So, placebo effect or not?
Certainly possible I suppose, but I haven't noticed it drawing a significant amount of juice on my S3 or my Note 2.
I've had Now running in the background on my Note 2 for over 9 hours and the battery is still at 92% (minimal usage, just on WiFi), and while I'm getting tired of being notified about the ManU match, it doesn't seem to be drawing an inordinate about of power to run.
Is the new ROM you flashed using a different kernel or a newer revision of your previous kernel? In my experience, that's been the biggest factor in terms of power consumption.

Well, I am using temasek's CM10 Kang (70 I believe, latest anyway)
and with the kernel that came with it.
I ve tried other AOSP kernel, but no boot at all, so...
What I think is that XXDLIB modem does has a noticeable effect on good reception over here, so maybe that s the factor here?
AccuBattery works great. But it's sometimes weird because there's a little differences in AOSP based custom ROMs and huge difference between MIUI based and AOSP based ROMs. Example, I got nearly 100% on MIUI and MIUI based ROMs but I got only around 90 to 92% on AOSP based custom ROMs. I don't know what's going wrong. So I would like to know is there any other ways to know my real battery capacity? May be something more exact way to know my real battery capacity. I've got root access with Magisk and unlocked bootloader.
Sorry for my bad English. Pls let me know if there were any other ways to know my real battery capacity. Thanks.
There are so many apps available on the internet that can give you every detail of battery uses and calculate the exact available battery time.
