The phone has hardware usb interface programmed to report as a composite USB device as all of those different devices, with dedicated USB endpoints used to transfer data.

Even if you can convince the computer that one of those composite devices is something it is not, you then have to convince the phone, by modifying the usb drivers, so that it knows what to do with the data.

Near imposible without access to engineering docs from the manufacturer.
[Desire Q&A, Help & Troubleshooting] baadnewz:
Probably not the newest dillema but here goes nothing, since I've read all the posts regarding battery life, almost all comments from custom roms threads about that and so on.

Right now im using MCR r8 w/ addition + a2sd. My apps list running on desire can be found here:

http://www.appbrain.com/user/baadnewz/apps-on-the-phone

Now my problem is that ive tried Pinky Desire, Leedroid, Nextsense, Delite and for the life of me, I barely make it through the day with the battery, like unpluging it @ 8 AM and pluging it @ 11 pm. Same goes for all roms metioned above. Tried with .20 radio and now with the newest version .30.

I must say I do NOT listen music on phone and I don't even use gps. I send 2-3 texts, and max 20 mins of call. I have 1 exchange mail running and 1 gmail account, i have friendstream syncing every 3 hours. I use Wifi and 3g. Im using it on vodafone romania, and since im in the city the gsm signal is good.

I tried using juicedefender, and setcpu with screenoff profile, they seem to make it worst (this is my apreciation, i didnt use any stat program to acctualy verify in % but for me so it seems).

To be honest im sick of hearing ppl "my desire last 4 days with music gps and 10000 mail accounts"

I even followed the battery recalibrate guide posted here on xda .

Anymore tips ?

Thanks, and yes I know this is the n+1 post about battery issues but all ive read the info is one inconclusive, some says they battery lasts 3-4 days on "heavy" usage" some they dont make it through the day (like me)

My desire has 2 mounths old.

For example. Last night arround 1 am i went to sleep and i was having 89% battery, this morning arround 8 i was having 72% left. No wifi on, just 3g data connection with exchange syncing @ 1 hour and gmail app for mail

have u tried non-sense rom?
[Desire Q&A, Help & Troubleshooting] baadnewz:
No, since im a really big fan of sense
[Desire Q&A, Help & Troubleshooting] Milamber:
I have exactly the same problem as the OP.

I have tried all sense ROMS, it seems the best ROM for me was Opendesire which doesn't use 'sense'.

So far Pays has been rather good, but I don't get more than a day from my phone... I too have tried the calibration setting that was on XDA but to be honest, I'm kinda stuck too as I dont know which ROM to use...
[Desire Q&A, Help & Troubleshooting] carlo0810:
Hi there, had the same problem as you and it didn't matter what rom I tried but still my battery kept draining, til I found out that I had a program that kept monitoring my desire's cpu constantly. Check for program's permissions where it won't let your phone go to sleep. Also check any program that constantly monitors your phone and refreshes every second.
[Desire Q&A, Help & Troubleshooting] baadnewz:
The only app running that monitors anything is advanced task killer
[Desire Q&A, Help & Troubleshooting] black818pro:
Carlo, do up mean that we can save some battery if we stop that program?

I'm also can't get a full day usage out of my Desire.
[Desire Q&A, Help & Troubleshooting] carlo0810:
The program that were giving me problems were OS info, and magic 8 ball, and quick system info pro, hope that helps
[Desire Q&A, Help & Troubleshooting] sultanbrunei:
I must say I totally agree with you. Changing ROM does not changes battery usage. It just won't last a day. I charged mine twice every single day. With mixed moderate-heavy usage of mostly internet basis.

Again, I totally agree with you. I couldn't believe with the slightest chance ppl could get 2 full days with heavy usage (4 hours of music, 4 hours of wifi, multiple account sync, facebook, few hours of browsing etc). I think they are just trying to bloat up things. (Eventhough they knew it's impossible) (or maybe they completely turned off their handset everytime they dont use the phone) :D

I also personally don't think a world class and professional company such as HTC will make highly variable units+battery performance for their products. Such as 3-4 days able HTC with half-day able HTC's.

Some ppl always argue that battery performace improve over time after several weeks of charges and discharges. Actually, they don't! Even if they do, the changes between 'just new' and after several weeks were not more than 10% differences. I got a blackberry 9700 and spare Nokia, and the battery last as long as ever started from second or third charges !
[Desire Q&A, Help & Troubleshooting] carlo0810:
Based on my experience you really don't need task killer constantly running in the background, android OS does a good job of killing programs in itself, and task killer sometimes kills programs that need to be running in the background and the OS then restarts the said program which takes up more battery
[Desire Q&A, Help & Troubleshooting] carlo0810:
Right now as I'm typing this I'm at 38% battery running for 1 day 20 hours and counting, by the way I'm using DeLite 1.1 as I really like sense, but as I said, it doesn't matter which rom you use, its the programs that drain your battery
[Desire Q&A, Help & Troubleshooting] baadnewz:
Yah i know what you mean, but I dont use the autokill function, I use to kill some programs i choose too
[Desire Q&A, Help & Troubleshooting] carlo0810:
Also check battery use in the settings, my android system use now is only around 5-7%, when i had the battery drain problem android system was constantly above 50%

Looks just like mine, are you on 3g? mine stays on standby for about 8 hours during work, but heavy use when I get out but mostly on wifi since I don't have an unlimited data package
[Desire Q&A, Help & Troubleshooting] LiL JRG:
I used to be a sense freak aswell. I soon learned to love AOSP builds, smoother, faster and much better battery life. Do a nandroid backup and then try OpenDesire, CM6 or Defrost (whichever you prefer) just to test the battery life for a day or two.
[Desire Q&A, Help & Troubleshooting] baadnewz:
Well to be honest thats why I bought the desire, for sense, since im a big fan of htc ui ever since diamond and manila :)

Yes last night was on 3g, but i turn on wifi @ work and @ home
[Desire Q&A, Help & Troubleshooting] carlo0810:
Could be the 3g, I would think that with you're usage its normal that it would drain quite fast...
[Desire Q&A, Help & Troubleshooting] elvis56:
It seems you have tried most of the tips from the various battery threads. However did you check your running services?(menu/settings/aplications/running services) I seem to remember for instance the skype services uses more than average battery.

Also, initially my battery life on leedroid wasn't great, untill i complete drained the battery, wiped battery stats and ever since then easily 36 to 40 hours connected to 3G, way more connected to 2G.

Also, check the mV value when your battery is charged, 100% isn't always the same. You can check this with spareparts, included in leedroid. Another thing i just remembered, people seem to recommend the overcharged application to check the mV value. On my phone that application actually seemed to drain the battery much quicker.

last tip for now, if you want to connect to 3G network set your phone to connect ONLY to 3g, NOT automatic 2g/3g.
[Desire Q&A, Help & Troubleshooting] ultracy:
some personal experience, I have stop using the little green thing, Advanced Task Killer Pro for 3 days. i realized my battery last more than slightly longer.

When i was using ATK, especially after waken from 8 hours sleep 20%-30% gone during idle. now without the ATK, these 3 days after i have waken only 5% gone during idle.
[Desire Q&A, Help & Troubleshooting] baadnewz:
Thanks I will set up to use 3g only. I know about spareparts is avaible from market, last i remember when it was charged was showing 41xx mV (still i cant vouche for my memory ). About draining the battery the opinions are split, some are saying that draining a li- ion battery will only shorter the capacity.

However im not using skype, and for now ive shorten my installed apps list, I will monitor running services from now on and will post my findings
[Desire Q&A, Help & Troubleshooting] w.0.o.t:
you can monitor your apps with the donate version of SystemPanel. perhaps there are processes that keeps your phone awake. :)
[Desire Q&A, Help & Troubleshooting] Surfinette:
13 hrs! So you last more than a day :D

Here are my tips to save battery and last more than 24H (in normal smartphone usage):

1) Brightness. Screen brightness can be a massive battery killer.... The default auto brightness is much too strong. In order to save battery, I use brightness at the lowest level possible: In most situation, a level below 10% is fine (the phone is even usable in certain situations (dark, airplane) at 0% which is actually still brighter than screen off). Only outside with bright sun do I have to use high percentages of brightness. Too swiftly change brightness level, I use the free app Brightness Profile, until someone can help with this request...

2) SetCpu. The main tweak is to set the Cpu at minimum value when the phone is idle, but you can optimize it further as mentioned in many threads in this forum. And for even greater battery life, you may choose to always slightly underclock the phone as most apps (except 3D games) won't need max Cpu speed.

3) JuiceDefender (the paid version): This tool is absolutely awsome and will let you save a lot of juice, especially through the Apps feature that will only activate data/wifi when the apps that you define need data connexion. All in all, thanks to JuiceDefender, I always have data/wifi off, except when I surf the internet, read/send emails, surf the market, listen online music... And apps that require data access but I don't want to will be blocked (so you won't have unecessary data access in the background). JuiceDefender also include features to activate data regularly for a very brief moment just enough for sync and email download. Lastly I use JuiceDefender to put the phone in aiplane mode during the night (which is also a significant juice saver). JuiceDefender is still work-in-progress, so the market version may not be the most optimized one, but if you pay for the app you'll be able to access to beta version ahead of their availability on the Market.

4) Adfree. I guess blocking ads should also help lowering battery usage

5) Double check your apps and those that constantly load while you don't really need them (I'm notably thinking of certain newsfeed apps that I have eventually uninstalled).

Regarding ROMs, I've also tested many of them and sometimes found meaningful differences in battery life... so far, my feeling (and it's only my personal feeling) is that the NextSense v7.0 is one of the best regarding battery life (much better than older versions of NextSense).

Lastly, it only takes a few days to take the habit of plugging the phone for charge every night when going to bed... so, imho the challenge should come down to being able to last a full day with heavy usage (feasible with my tips)

Good luck with your battery optimization

HOW in the world did you manage to make android system use to only 5-7% ?

Can you direct me how ? Mine is averaging 36-47% all the time
[Desire Q&A, Help & Troubleshooting] elvis56:
Not too sure about the overnight charging. On my phone this gives bad results because i run into the charging to 100%, then discharging to 93% then charging again thing. And usually in the morning battery drops straight to 93% when disconnecting from the charger.
[Desire Q&A, Help & Troubleshooting] baadnewz:
From my experience juicedenfender and setcpu only did worst (i know it sounds stupid and ilogical)

I am charging my phone every night but experiencing the same issue as elvis56

Adfree im using already and Ill try to lower screen brightness althou here is summer and the sunlight is pretty strong even indoors or in car

Now ive flashed delite 1.1, shorten my installed apps list, installed y5 battery saver (does one good thing, turns wifi off when is not connected) will see what will happen

@denis_sianto 7% i had too with mcr r8 maybe u have an app that kills cpu
[Desire Q&A, Help & Troubleshooting] Surfinette:
Here it depens on the ROM. With some of the I got the same result as you (93% after overnight charge), but with NextSense 7.0 I get 100%
[Desire Q&A, Help & Troubleshooting] andycted:
Probably the wrong sub-forum, probably a new thread wasn't needed, but well...

Solution n1: nandroid backup, factory reset, try to stay for a couple of days without installing any applications and see if it gets better. That way you can narrow it down to some application or to some system settings.

Solution n2: get power tutor, current widget, system panel. Monitor the system, especially on idle, and find what's draining the battery

Solution n3: get a new battery and see if yours is defective/old. By having two battery you can also switch them
[Desire Q&A, Help & Troubleshooting] d3sm0nd:
I'm using this ROM:

http://xdaforums.com/showthread.php?t=732246

With SetCPU profiles (Screen off - 250MHZ, overall underclocked to 768MHZ as it doesn't impact performance) and calibrated battery.

It lasts for 24 hours with mid usage which is perfect for me...

No matter what we do... we have a very powerful device with a big screen, it's normal to drain battery fast... if you want good battery life go buy yourself an old Nokia 3310. :D

[Desire Q&A, Help & Troubleshooting] Sarsippius:
If you're a heavy user android system will still be fairly high, try charging the phone, unplug it and let it sit idle for a couple hours. Then check it and if android system is not down around say 10% or lower then something is not letting the phone idle.
[Desire Q&A, Help & Troubleshooting] PhysX:
same here...

now im trying to monitor my stuff too, coz its really annoying

maybe im going to find the app that is eating my battery
[Desire Q&A, Help & Troubleshooting] carlo0810:
I agree with this suggestion, charge your battery then just let it standby for about an hour or two and then check battery use android system should only use about 5-8% or less in standby, if not, an app is not letting your phone go into idle, magic 8 ball for example has permission to prevent phone from sleeping...

But overall, do you guys think that by using a Rom without Sense could increase battery life?
[Desire Q&A, Help & Troubleshooting] fwers:
instead of running ASOP, i run a stripped down version of official sense rom, i installed psychosis, and after installing that i remove even more stuff that i don't need. i installed version 5 yesterday and i am impressed with the battery life.. 21 hrs used, 50 so mins on the phone(HSDPA network), 28 mins for display, 2 sms. I don't know but for me ASOP sucks more juice, in the form of OJ death, but i do miss some features that ASOP have that official don't have, anyways... it's trade off that for the moment i am happy to make ..

we are having very powerful device with us and battery drain is normal with it....

I just wanna say that i have tried almost every ROM from this forum on my desire and currently, i am fully satisfied with AuraxTSense v7.3 for sense ROM and OD for Non Sense ROM....

Battery drain is almost same for both the ROM's for me.....24 Hrs Max..with 1 Exchange Account (Push), 1 Gmail Account, Full use of Calls and GPS....using wifi as and when available.....That's it

The latest OpenDesire gives me far far better battery life than any of the 20+ sense roms i've used previously. Used to be a Sense only person too, but found Opendesire had come on a long long way since I last used it a few months back. Theres loads of themes for it too, including Sense style status bars etc...

Not to mention I can now use a Wii Remote to play games xD awesome!
[Desire Q&A, Help & Troubleshooting] snapilica2003:
You can try using a custom init script and installing the governors talked about in this thread. But if you're using MCR you have to mess with it a bit (that script is for OpenDesire).

Anyway head over to Paul's R8 thread at Modaco. Someone changed the scripts to make them work with MCR and he's saying he get's a 3 day average with pretty heavy usage.

I've got them on since this morning and i'm at 82% battery and 8h uptime since last unplugged. It seems i do get a better battery life.
[Desire Q&A, Help & Troubleshooting] ryanrich:
Yeah I used to only use OD and it has great battery life, until the OJ dies, then your phone can be completely drained in a matter of hours. Until that bug has been resolved it's just not an option for me...

hello, usually when i record videos for a long period of time, about an hour or so, but maybe less i don't really know, it tends to not save my videos. i was thinking it was probably because my storage card doesn't have enough space, and so it doesn't save it. shouldn't it at least tell me its out of space, and stop recording at that time?
[Touch Pro2, Tilt 2 Windows Mobile General] DJ Palmis:
I think video application developers did not handle correctly more than x minutes.

Where x may be something related to the number of frames, buffers dimension and so on.

I never esperienced this issue because my videos are short.. I can't test your issue.

You should try another third part software.. I'm looking for a video recorder eith PAUSE function.. BUT I CAN'T FIND IT! :(
[Touch Pro2, Tilt 2 Windows Mobile General] Miami_Son:
When you hit record the program has no idea how long you plan to record for so how could it warn you? Once it reaches the limit of storage space it simply stops recording. It would be better if it simply stopped and saved what had already been recorded, but who uses a cell phone to record an uninterrupted hour's worth of video? The vast majority of people only record 3-5 minutes of video at a time or less. If you need to shoot video for long periods a dedicated video camera is a much better choice than a cell phone.
[Touch Pro2, Tilt 2 Windows Mobile General] uncleswoop:
is your memory card name brand? i had bought an evo and got a no name 32 gig sd off ebay. next thing i know im losing saved videos. or ill watch them once, go to play it again and it would tell me the file was corrupt. got rid of the 32 gig sd and went back to the 8 gig and it worked like a charm.

They do let you downgrade. I open a new line for my little brother under my name.

I call customer service and told them to downgrade to the $10 plan with no problem.

My question was referred to the htc hd2 since it's a branded t-mobile phone i needed the $30 plan. I just want to know if there was any way around that and run the $10 and if they would find out. Thanks,
