i don't see the lights.so files and i'm on chuckyrom gtx and shubis 1.5 with ...50.2.02 radio rom. can i just copy the light file in the directory or where can i find it?
[HD2 Android Q&A, Help & Troubleshooting and Genera] sylau90:
Hey mate...same here i got 5-10ma with shubcraft v1.5origfont...without any tweaking or replacing the any of the system files....it just make no difference...

here are my SETCPU setting very useful...this gonna help everyone heaps...please follow,actually i got this setting from the CPU governor thread

everything related to connection off(3g,wifi,gps...etc)

here are some example:

WIFI on- device sleep: it'll bring you up to 200++ma

GPS on- device sleep: up 60++

NO MATTER HOW MANY WIDGETS YOU HAVE,its doesnt matter...not related to BATTERY

here comes the setting:

brightness-middle level

advanced task killer: set to auto kill when screen off

set cpu setting

1)on the main-MAX 883, MIN 245...scaling: ondemand

2)go to profile tick ENABLE and add profile...got profiles 4 here...

A)battery<50%, MAX 768, MIN 245...scaling: ondemand...priority: 100

B)Temp>50.0 Celcius, MAX 768, MIN 245...scaling: ondemand...priority:100

C)Screen Off, MAX 245, MIN245...Scaling: userspace...priority: 100

D)Battery<25%, MAX 652, MIN 245...Scaling: ondemand...priority: 0

3)go to advanced tab:set as below

Sampling rate: 20000

up Threshold: 30

Ignore Nice load: 0

Powersave Bias: 0

TICK SET ON BOOT & then APPLY...

Everything done...Every user can use it and try it...It definitly will help you...this is the easiest way...NO TWEAKING...NO replacing SYSTEM FILE...Cheers...

FYI: I use stock WINMO ROM from telstra and the FREE SD CARD 16GB that comes together with the device...I change NOTHING...
[HD2 Android Q&A, Help & Troubleshooting and Genera] hazard99:
So to day I went to work happy go lucky that I was gunna get the same low power drain and instead I got 50-60ma ... So i restarted opened setcpu and then the i got less than 5ma in standby.

Something is fishy with setcpu and and super user permissions Me thinks.

Its like permissions dont set properly as they should.
[HD2 Android Q&A, Help & Troubleshooting and Genera] xlr8me:
Am trying this right now as I found with other method just renaming the file does not work. I found after recharging it it still went up to 55mA in standby.

Will give feedback over the next 24hrs.

Thnx mate. :)
[HD2 Android Q&A, Help & Troubleshooting and Genera] anap40:
I get 5-8mA with shub 1.5 after replacing the light files. I don't use setCPU and as you can see it isn't even necessary, I am getting extremly low battery drain without it.

I had to replace the files about 3 times before it finally "stuck". It kept bouncing back up to 60mA. But its now been about 36 straight hours of 5-8mA
[HD2 Android Q&A, Help & Troubleshooting and Genera] sylau90:
Your are welcome...hope it'll help you save your battery heaps...I just try to make things simple...without replacing anything...as I said few post before...
[HD2 Android Q&A, Help & Troubleshooting and Genera] Hd2Menace:
wow, did the light.so file thing and my battery drainage went down dramatically. i also did a mixture of all of the above with the setcpu, etc. will really see if it works tomorrow when it's fullly charged and i'm at work using it. *crosses finger*
[HD2 Android Q&A, Help & Troubleshooting and Genera] songokussm:
I'm on Shub 1.5 stock PPP and with setcpu set for conservative (literally nothing else and i have lots of apps and widgets installed) my sleep usage with edge (on att network) is 5ma. The edited light config file did nothing for me unless current widget can not measure lower then 5ma.

I very much appreciate the work though! thank you.
[HD2 Android Q&A, Help & Troubleshooting and Genera] simeezee:
I'm using shu8i's 1.5 buid, original font.

I need to replace the lights.qsd8k.so in two locations.

1. system/lib

2. system/lib/hw

After i replaced the file lights.qsd8k.so in the above two locations, the file type is not executable compared to other .so files. Does it matter if it's not executable? Because I got about 60mA batt drain regardless. The fix doesn't work for me.
[HD2 Android Q&A, Help & Troubleshooting and Genera] galapogos01:
I have tried the file attached in post #42 w/ Mattc Sense v1.6. It appears the same size as the stock file and either way (or with it deleted all together) I am seeing 66mah on sleep w/ zImage from 20200823. Any ideas?
[HD2 Android Q&A, Help & Troubleshooting and Genera] sylau90:
Please refer to this....try to setting up like what I posted there...It might help...Quite a number of users find that replacing and renaming the system files are useless...personally,i think it does nothing too....i got 4-10MA now...and read the comments from conservative CPU GOVERNOR...that thread is more useful...
[HD2 Android Q&A, Help & Troubleshooting and Genera] securecrt:
I find that this battery drains problem is related to the keypad backlights before you enter Android.

It means when you press the shortcut of AndroidLoad in the WM you should keep the keypad backlights ON.

if the keypad backlights is off you will get a very high standby current (about 60mA) in Android. I tried several times and find this amazing issus. Now I get a very low standby current 5mA. I use setcpu and ATK.

Please try it.:D
[HD2 Android Q&A, Help & Troubleshooting and Genera] GStar01:
Thats very interesting, how did you measured the mA it nead? So you think it isnt not right on, but also not right off?
[HD2 Android Q&A, Help & Troubleshooting and Genera] buzz killington:
Very useful widget

This is a very useful widget, Thanks! Now I don't have to wait overnight to get a good read on battery life.

I have several builds running so I tested them all. With my rom/radio combo I was getting very good battery use with Mattc 1.6b, Shub 1.5 and HyperDroid, they all ranged between 3-7ma.

I also tried FroyoStone V2 and Mattc 1.7, these two used quite a lot - 50-60ma. I almost gave up but I really wanted to use Mattc's Sense build so I ended up putting in michyprima's kernel build and that worked great, got it down to 5-7ma with wifi/sync/3g turned off. I'm a happy camper now :D

Solved the battery issue on my device

I replaced the lights file and after reboot 3 mA were measured. After one hour the current consumption increased to 55 mA. In this time I started and stopped some apps.

At the end I found, that the GPS makes the problem. After a reboot the GPS is down.

If I start an app with GPS required, the GPS will started but not stopped by closing the app.

So I switched in the settings the GPS off.

Now I have 3 mA. After each usage of an app which starts GPS, I have to stop GPS.

It's very easy with Quick Settings.
[HD2 Android Q&A, Help & Troubleshooting and Genera] deli_gt:
What SD !!!!

Power consumption is also related to what MicroSD you all have so please ON EVERY POST INCLUDE YOUR SD so we can get conclusion witch is the best battery saver!!!
[HD2 Android Q&A, Help & Troubleshooting and Genera] buzz killington:
I'm using the stock 16gb sandisk class 2 card, though I doubt the huge difference in power consumption is coming from the cards, it's much more likely the different builds and combo of roms. I see several posts of high power consumption from the stock card yet I've been able to get good battery with most builds.
[HD2 Android Q&A, Help & Troubleshooting and Genera] deli_gt:
I can confirm 100% SD is big part of the consumption. with transcend card, on every combo I tried it had high drain.
[HD2 Android Q&A, Help & Troubleshooting and Genera] xlr8me:
Yes it works. Very stable and consistent 3~5mA in standby. Many thnx dude :)
[HD2 Android Q&A, Help & Troubleshooting and Genera] buzz killington:
Did you turn off the disable power management in the winmo registry? To be honest, we're talking about standby battery usage here, the sd card shouldn't be working at all. I get good battery because i turned off all the sync so the only power being used is used to power the radio and wait for you to turn the phone on.
[HD2 Android Q&A, Help & Troubleshooting and Genera] deli_gt:
Sure I have, in chuckys roms they are disabled on beginning still I have tried many combos and cant get stable ~6ma but ~10ma with my 8gb verbatim class 4
[HD2 Android Q&A, Help & Troubleshooting and Genera] sylau90:
Haha...cheers...you alright...I just hope everyone can focus on some major things like CPU,processor stuffs...but not system file&SD card...I already mentioned these couple of times before...Everyone please try this et up before you replace any system or buy a NEW SD CARD just for better battery life...

[HD2 Android Q&A, Help & Troubleshooting and Genera] aussiebum:
Hmm, I've just had the same issue, even though I'd been recharging more than once and hadn't happened before. I think I triggered it by charging my phone to 100% in WinMo, then booting into Android and then charging it again while it was nearly full.

Going to need to investigate some more.

Of course, as sylau90 is saying, best solution is not to have to mess around with system files at all. If you can't be bothered messing around, just try out the latest Android builds that are reported to have low standby drain :cool:
[HD2 Android Q&A, Help & Troubleshooting and Genera] aarons6:
how many of you guys are using a sense build?

i am trying both froyostones v2 and mattcs v1.7 and im getting ~50mA at idle and around 150-250mA in use..

changing the files and setting setcpu doesnt help. ive even set setcpu to use 256-480 all of the time and it still has high power drain.

i just switched to miris rom and i have the stock 16gb class 2 sd card.
[HD2 Android Q&A, Help & Troubleshooting and Genera] aussiebum:
Of course. That's why I updated my post earlier today to mention the conditions on how to achieve 5~10ma standby.

The whole point of that post was to assist people who'd tried WM battery settings, various SetCPU profiles and different kernels but still getting crappy high standby drain. Personally I'd just wish all chefs would properly test their builds for battery life before releasing it to the inexperienced masses so we wouldn't get a zillion people asking silly questions, but hey, this is XDA and the whole point of this forum is to try out experimental new stuff :)

I disagree on the bit about widgets though. If you have a widget that automatically attempts to download weather / facebook updates / etc, of course that's going to drain your battery faster during standby.
[HD2 Android Q&A, Help & Troubleshooting and Genera] aussiebum:
Try rebooting and see if you still get the high standby drain. I had no problems in the brief time I tried Mattc 1.7
[HD2 Android Q&A, Help & Troubleshooting and Genera] xlr8me:
Aussiebum were you using the 2 file replacement method as mentioned below when it went up after charging?

http://xdaforums.com/showpost.php?p=7949689&postcount=42

I am about to test that theory but am concerned now it might now work. I am probably gonna leave the SetCPU method and recharge it tonight tomorrow and see if the standby goes up again before replacing the two files in that link.

[HD2 Android Q&A, Help & Troubleshooting and Genera] xlr8me:
For anyone interested have now replaced the two files and noticed immediately the screen activates correctly with the hardware buttons.

Previously there would be some times where the screen would not wake up when pressing the end key.

So far so good and again low standby current 3mA. About to do a charge and see if afterwards it changes.

Standby...
[HD2 Android Q&A, Help & Troubleshooting and Genera] aarons6:
i dont know my phone seems to be doing something now.. ive had it on the charger for about an hour and every time i turn the screen on it says 350+ mA

this is a new build of froyostone v2.. i like how that one looks the best and gives me the fastest net speed.

im wondering if its re arranging the files in the ext2 system.

whenever i install linux on my pc the first few days the hard drive is going crazy because of the way linux manages the file system. since these builds are based off linux i wonder if they have the same background managers.

as soon as i wake the phone up the mA drops down to around 120-150.. its only in the 300s with the screen off.

of course this made my battery go dead in a couple hours and i had to plug it in.

im going to give it a few days to see what happens..
[HD2 Android Q&A, Help & Troubleshooting and Genera] hoobledi:
I´m on shubcraft 1.5 stock with an Elegancia gtx 3 ROM.

Tested your method and it works for me!!!

When the lights are off and I boot to Android, I have around 60 mA standby battery consumption.

When the lights are on, I only have 9~10 mA in Standby under Android!

That´s without setcpu.

Everybody with a high battery drain - try it out!!!!!!!!! :D
[HD2 Android Q&A, Help & Troubleshooting and Genera] Johev:
Sorry for this noob question, but I have been reading the adroid posts for a while now. I am very interested in the adroid build for HD2. Not that I am not satisfied with my artemis rom (as I still fail to see the problems with WM when you are used to work with it).

But because I am curious on how good adroid is, I would like to try it out.

The thing that puts me off is the battery drain. This thread really boosted my confidence in the adroid builds and I would like to ask you, if someone can tell me how much is the normal drain in WM (standby and load).

As some people reported 3-5 mA standby, I was wondering if that would not be the same usage as in WM. If yes, then in theory the battery life would not differ much, and that would be something I would definitely be able to live with.

Thank you all for your answers.
[HD2 Android Q&A, Help & Troubleshooting and Genera] xlr8me:
That is perfectly normal as the charger supplies more to re-charge the battery.
[HD2 Android Q&A, Help & Troubleshooting and Genera] xlr8me:

[HD2 Android Q&A, Help & Troubleshooting and Genera] xlr8me:
Ok,

So we now have 3 possible solutions.

1. Replace two files with older froyo versions on sdcard as per post 42 page 5 by Aussiebum

2. Tweak SetCPU as per sylau90 post 136

3. And now how you boot-up android (keypad lights on/off) coming from WinMo and clicking Harret as per securecrt post 146 page 15.

I can confirm No 2 works. Am currently testing No 1. And tomorrow will test No 3

Some feedback on Version 1. The battery recharging is fast and I can see a consistent 351mA being pumped from charger. With Version 2, I noticed some fluctuation and slower recharging but I probably need to do more testing to verify...
[HD2 Android Q&A, Help & Troubleshooting and Genera] wheeliemonster:

[HD2 Android Q&A, Help & Troubleshooting and Genera] Tallon:
This battery drain issue is strange ... I am sure there is a logic to it, but I sure don't understand it.

I have had the same ROM and Radio over the last week and mattc's latest Android. I tried replacing this lights file and sure enough my drain on standby (with BT and WiFi on) went down from 60 to around 12 or so. Thinking I could improve on this, I installed JuiceDefender to knock off BT and WiFi etc on standby. However after a reboot I could not get the drain below 60 ... with or without JuiceDefender.

Having read comments from others about the hit from the SD card (I am using a 2GB class 2 card), I ordered an 8GB Transcend class 6.

In the meantime on my class 2 card, I replaced the android build again, set up my apps including CurrentWidget and JuiceDefender etc and replaced the lights file.

I just checked and my drain on standby has been going as low as 4mA on occasion!!

Not that I am complaining, but I just don't understand the logic...

[Epic 4G General] NeonMonster:
When I got my Epic the battery was at 50% like expected. I immediately plugged it in when I got home and it seemed like it was charging because the charging light was on and the battery indicator was showing charge.

About 1 hour later I had to leave for class and I unplugged my epic. It stated it was 15% battery left and gave me the sad low battery notification.

I plugged my epic into the wall at school and let it charge a good 2 hours. Throughout the charge the battery would NOT GO ABOVE 15%. I finally unplugged it a few minutes ago, and STILL the battery is at 15%.

Is there any way to reset the battery stats or is this a faulty unit?? I called my radioshack nd they stated they can do a phone swap for me BUT THEY DON'T KNOW WHEN THEY WILL GET MORE EPICS IN. WTF. I obviously can't use a phone that won't charge..... I saw a similar problem on androidcentral forums, where someones epic wouldn't charge over 80%.

My radioshack lady said to take out the battery and reset the phone. I've done this 3 or 4 times and still the battery registers 15%. :(
[Epic 4G General] blakehess11:
I'm having the exact same problem except my phone always thinks the battery is at 0%. Even when plugged in to charge, the phone will still occasionally die. It's very likely that I'm just making some silly mistake though, as the Epic is my first Android phone.
[Epic 4G General] NeonMonster:
I had on USB debugging but I don't think that should affect charging through usb. I don know what's wrong with the charging port or the battery. But its definately going DOWN. Now its blinking at 0% with no way to charge it.

I'm wondering if I let the battery die and try to charge it to see if it will fix the battery.....
[Epic 4G General] Phen0m:
Same issues until i plugged it into a wallcharger.. now im good
[Epic 4G General] Phen0m:
meaning a non usb charger
[Epic 4G General] NeonMonster:
I have tried the usb wall charger that came with the phone, and also a generic microusb charger. Both light up the notification charging light, and then the battery shows the charging..... still won't go above 15%.

Argh! :(
[Epic 4G General] jbarajasp:
easy fix guys....

be sure to use the original charger and usb cable.

plug in the charger to the wall, then plug the usb into the charger, then plug the phone into the usb....

follow these steps exactly and it should start charging......

(in the future, dont let your phone completely die)

PS: this issue affects ALL epics when they die completely so dont bother taking your phone into sprint. they will not replace it because the replacement would do the same. (2.2 should fix this..... its only a couple weeks away)

hope that helps!! ENJOY YOUR EPIC!!! :D
