I had never done this on a android phone until tonight and these are the links I used. Although I have flashed firmware on many phones so be careful.

Debrande Firmware

Gold Card

I would say my sound quality is very reasonable its not the best I have had for sound quality but far from the worst. In comparison to my last to phones it isnt as good as my iphone but is slightly better than my hd2 if that helps :rolleyes:
[Desire General] TurkzZ:
on mine it sounds like the treble setting is way to high, wish they had more options or there was a free program to play with the equalizer to test it out, what ever happend to the dolby enhancement in the desire? is that going to be activated or added in an update or sommin
[Desire General] Aitese:
Hi all...I can confirm that de-branding from the T-Mobile ROM has solved this issue for me.

What on Earth are T-Mobile thinking?
[Desire General] landwomble:
Me too

Just applied the update using goldcard method, and then done the HTC OTA update. I've not checked it against my reference stereo/iphone setup - but it's LOUDER! Result, I'd have thought about returning the phone if this wasn't fixable.

Battery life seems to be improving too with time. Happy bunny now.

[Desire General] Aitese:
What I forgot to add to my last post was a word of caution.

THIS WILL CERTAINLY VOID YOUR WARRANTY.

If T-Mobile or HTC get wind that you've been fiddling with authorised software they'll not help you. I've got a pretty comprehensive insurance plan so if ever my phone needs repair and they get wind of it, well...I'll smash it frankly and pay the excess for a new one.

Ooh I AM naughty!
[Desire General] TurkzZ:
they cant find out wirlessly right lol,
[Desire General] landwomble:
not entirely

If you properly brick it doing this, then you might be on your own. If the hardware fails, normal warranty rules should apply. I would say the onus would be on them to prove that what you'd done had broken the device. I don't remember signing a EULA saying I wouldn't apply official HTC ROMS to my device.

I know Google and the Nexus One have some clause that if you root it you're out of luck but they don't have EU customer rights legislation.

Also, I've returned a WinMo phone to HTC UK under warranty that had a completely custom ROM on it before now - fault was with a scroll ball i.e. hardware but the agent I spoke to was OK about it. It was returned with a stock ROM and a note on the work sheet moaning about a custom ROM but that was it.

T-Mobile, on the otherhand, I suspect would be a bunch of funts about it.

To be fair, they'd be unlikely to notice in the store as other than the T-Mob logo on boot it looks the same. You could just claim ignorance...

How would I go about returning to 100% stock on my N1? I'm preparing to flash the stock ROM via Amon_RA's recovery console, but after that, what steps do I need to take to go back to the stock recovery console?

Thanks in advance!

Any pointers for increasing battery life? I've disabled live wallpapers, picked a dark background, set friendfeed etc to update every 4 hours, and it's still not great. Phone is new, should I expect battery life to improve as battery gets used a bit?

Are task killers worth using? Seems to be some debate that they might actually cause more problems than they solve.

I've gone through forum and found lots of generic advice but would appreciate any ideas people have tried on the Desire.

Do I *really* need to wturn off wifi when I'm not using it? Isn't the phone smart enough to not use it when a known-network isn't present?

Cheers
[Desire General] isaw:
From my experience i would advise against having a task killer running.

I used to have one running on my N1 and thought, "Great, i can free up memory". But you really don't need to do that with Android.

Having disabled it from running, I get to teh end of the day and I have between 75 and 85 battery, after having done a fair few phone calls, some net fun and data access.

I still have a task killer but I use it infrequently and dont have it running - i let it "kill" itself after running it.

I found they take up a good deal of battery life. But that's just my opinion.
[Desire General] Waza_Be:
Of course!

The classic task killers kill services that are sleeping and do no eat battery.

A few minuts later, on some receivers ( connexion to internet, message or SMS received) these services will restart, and that's where they are eating battery.

If you hadn't killed them, they would have done that without eating battery.

Waking up and then going to sleep is really less battery-eater than restarting the whole service.

So, please forget about all these task killers or do that in a smart way. Only kill your game or the latest app you used!
[Desire General] zzleezz:
Battery life will improve over the first weeks use. Needs a few charge cycles to achieve full capacity.

Although the battery life might not be as good as some other "imore ipopular" handsets at least you can buy a second reasonably cheap battery if you know you will be a couple of days away from a possible charge (camping etc).
[Desire General] Ramedge:
You serious? I am guessing you're referring to the iPhone, the smartphone that is on charge more times than its off charge?

My Desire hands down beats an iPhone for battery life by almost 100% - only ever got 1 day of an iPhone at best - Desire is approaching nearly 2 days full usage, I am no lite user either.

For battery life the Desire is one, if not the best out there at the moment.
[Desire General] landwomble:
thank christ for that, i presume it improves after a couple of charges. mine was new on friday and the battery's pretty uninspiring so far...
[Desire General] Ramedge:
My Desire has been up for 21.5 hours and has 3 bars left (according to the settings battery meter) but I've been driving around most of the day with spotify on listening to music, quite a bit of surfing, emailing, calls and a few texts.

I reckon it's probably got another 5+ hours to go yet.

My phone is quite new and battery life is starting to improve daily now.
[Desire General] popkid:
Hmm... struggle to get more than 5 or 6 hours out if mine under relatively light usage, maybe 20 mins calls and 3 or 4 texts, if I use browser it flatten quicker still, the battery use status usually says Android OS itself has used most battery.

Hoping it will improve, at moment it is poor compared to my TD2 with a smaller battery

[Desire General] sgb101:
had mine about 6 days and my battery is ver poor at the moment. however i remember thinking that about the G1 at first and it got better.

still was luck to get a full day from it. however i went to europe the other week (from uk) so turned all roaming data and syncing off and it lasted 4 days:).

fingures crossed battery life increases on the desire, gor a car charger on orded fron fleabay so i should survive:)

i loved my G1, and found it hard to upgrade, first time thats ever happend, but wow this desire is differnt class, my wife has the iphone and is green:D and my 16 year old son is gutted he got the hero only 6 months ago.

Re: desire battery life

I've been running my desire for nearly two weeks now.

As usual WiFi & gps are the main culprits.

On average, I have exchange & GMAIL push on 3G all day with a bit of Facebook, sms & several min long calls without going past the three quarter mark by 5:30pm . However as soon as I switch on WiFi at home for browsing, reading news feeds, market etc, bang goes my battery!

Turn off 3G and sync and use it as a phone.......great battery life!

[Desire General] OnlinePredator:
Yea not sure how you guys get good battery out of it. I have everything off, dark background, no synching due to having mobile network off (only thing setup to sync is email every 2 hours). I take a few phone calls maybe 30-40mins, do about 15 mins of surfing, 30 mins of music through headphones at low volume, and a game for 30 mins. That pretty much concludes my battery life for the day (is usually at around 20% left by the time I get home).

I find if I browse the market and download/install apps, my battery will go down very quickly.
[Desire General] R3dD3vil:
Got my desire for a week now and it lasts me 2 days woth some movies, wifi and messaging. if i go even lighter, only messaging and calls it lasted me almost 4 days. it has great battery in my opinion, better than my old hd2 and even better then my old old diamond :)

Over in General we found an issue with the calendar app keeping the phone from going into sleep mode - That could be a cause for poor battery life.

My Desire have no problem on battery so far tho, 1½ day with normal use is no problem. litle use i can use it around 2 days, but with alot off things running i would say for sure it works over a full working day.
[Desire General] gleepface:
Mine has been running for 20 hours now, I have mainly been calling, texting, surfing the net (mainly facebook), and playing a game a couple of times.

I'm not really sure whether this is good or not, I would rather it lasted longer than this, as it is due for a charge within the next few hours, and this is a bit of an awkward time to need to charge it. If I wasn't off work today I'd have a dead phone before I got home.

I don't like to charge mine before it tells me too, I like to think it'll improve the battery life over time? Is this right?
[Desire General] Wextercz:
those batteries are not affected by memory effect. charging everytime you can is better than drain battery to 0%
[Desire General] choccy31:
HTC have said there is a software issue with battery levels hench the charging issues. Fix in the future they suggested.

Weather this effects the actual life of battery not sure.
[Desire General] cgrec92:
I have just come from the HD2

At the beginning, everyone agreed that the battery life was god awful, and a month or so in everyone reported that the battery life was outstanding!

I can confirm this, to start with it wouldnt last me a day, by the end of it i could leave 3g and wifi on all day with everything running in the background and get a good 2 full days out of it!

I just received the desire yesterday, i gave it a full overnight charge and i must report that for the first charge the battery life looks very promising

I have used the phone VERY heavily even for me with about 100 texts, an hour talking, an hour on the internet and syncing every 15 mins or so and i have 2 bars of battery left, and i said, the battery is only going to get better!

You should look at power management tips for the HD2 as most of them apply, for example disabling 'automatic backlght' and setting it yourself because that alone can add about 30% to your battery life.
[Desire General] str355:
currently at 2 days 15 hours with 6/10 battery bars left.

i have gps/wifi/internet disabled and turn them on with the settings widgets when i want to use them. screen brightness at about 20%

the battery is great IMO
[Desire General] dr.mid:
Guys could u please tell if I should when receiving my phone charge it directly (full charge) or it's better to empty it completely and then charge it ?

Thanx :)
[Desire General] Ommadawn:
Modern batteries don't need to be discharged before recharging. The best bet is to top up the battery whenever you can, in my opinion.
[Desire General] dr.mid:
that is 100% right . I checked it .

but I readed in this thread that some guys waited until the battery is empty then charged it at the first time , so this is not corect ,is it ?

big thanx :)
[Desire General] Ramedge:
Re: desire battery life

I know people say that discharging and then fully charging the phone has no effect, but it does seem to from what I have observed.

It is worth trying a full discharge of the battery and then charge it while the handset is switched off for 3-5 hours. For me, this approach has seen my battery life go from 10-13 hours to over 25-30 hours.

I think to any one desperate to squeeze some extra life out of their battery, you've got nothing to lose by giving it a go.
[Desire General] ardsar:
There is a site (do a search for Battery University) that answers all these questions. A new battery does take several discharges to become conditioned. The main reason for completely discharging the battery is to calibrate the battery monitoring tool. It is suggested that this should be done say one a month. Fully discharging can damage Li ION batteries, however there is inbuilt protection - you can not completely discharge a battery - the phone switches off around 3.4 or 3.5 V (cant remember actual value)

Re: desire battery life

had the phone for ten days, I admit that for the first four five days it wasn't spectacular but now it lasts well over a day with heavy usage. I would disable live wallpaper or choose one which doesn't use sensors and is mainly black. shake them all for example is fantastic but eats through battery like mad, I think starfield is a lot more battery savvy.

I think gps eats quite a lot of battery as well as bad 3g reception, so as usual turn gps off if you don't need it and set airplane mode if you are in a place where you know there is no coverage, the phone scrambling to search network eats a lot of juice.

one more thing that eats battery is a high brightness and a light screen color, such as a whitish background,

I've just came back from an hour or more of bicycling with sportypal +gps and listening to mp3s, auto brightness in a very sunny day, took a couple of photos and had a 5 minutes conversation, 3g only since my network hasn't normal gsm.

battery is still at about 80%, which isn't bad at all I reckon...

will post more tips when I remember them, meanwhile just wait for the battery to get better in about a week...

Re: desire battery life

discharging a battery to 0% has the danger of damaging it however all modern batteries have a protection about it, the other issue is that modern batteries lose more lifetime when they are in the 0-20% range and close to 100% to a lesser degree that's why they are stocked at medium charge.

that said discharging your battery till your phone turns off has the good side of calibration and maybe even extending the charge capacity.

[Desire General] RaptorRVL:
Well, for li-ions and lipo's there was (or is) the '80% rule'. Never make it go below 80% discharge (read: below 20% charged), becuse apparantly that would shorten battery life.

As you can find at the battery university site, it's also stated that small discharges are preferred over big ones.

The reason why battery life increases over time has to do with two main factors I think.

1. When you first have a device, you play with it. - a lot - And perhaps it takes some time before you turn off services you don't need. First you might fiddle with it a lot and after a week (or two) you only use the device in a more basic way.

2. The calibration of the battery chip. I have attached a really simple (and perhaps not 100% scientifically correct, 3v and 4v are just in there as an indication) image that shows what the whole calibration thing is about.

There is the red line, the typical voltage drop of a li-ion battery when being discharged.

Then there is the green line, the line the battery chip tries to calculate. To give you a proper average % reading. The green line might take a few charge/discharges because.. it's an average! :D

When you check out the last bit, where the curve drops down. That would be the '80%' rule. It's said that discharging further in that region shortens battery life.*

* However, there has always been some debate about that. And some say more modern (lipo) batteries don't have that problem anymore. And not sure how it relates to modern li-ion batteries.

edit: Note, that after the chip is calibrated you are talking about 35% left which is about 20% of voltage left. So the '80%' rule would start at 35% calibrated battery. Just to make things more easy :D

See dotted line, although I believe it should actually be higher... Or perhaps the curve should be lower. But it gets the job done as example I guess.
[Desire General] djind:
I just found out that the wifi setting y default is 'always on'. Anyone knows when it turns off when set on never when charging? I would imagine it should turn off shortly when screen is off. But I checked after 10 mins or so and it still was on. Should have some impact on battery life.
[Desire General] landwomble:
2 things

turn it to turn off after 15 mins inactivity and tell it to drop mobile data when not needed: it'll connect on demand then
[Desire General] paprkut:
Mine did this, I assumed it was normal coming from a iPhone. My battery got really hot after a lot of usage so I rang Orange customer service and they replaced the phone next day. Battery life is a lot better!
[Desire General] djind:
I will do just that then. I thought when that option was not checked, auto updates would not work. Probably uses alot more power when checked. It was already an improvement when I changed the wifi settings.

[Desire General] subharmonic:
I just can't see how anyone can get so long out of this battery.

I can't see how you would get that sort of lean battery use with all of those functions on.

I primed my battery with an initial 12 - 15 hour charge when I first got it.

I installed Juice Defender, and it's plotter app.

So far this morning (since about 7am), I've used it to browse the internet maybe in total for about 20 mins (if I'm lucky - also the odd Touiteur update) - according to my battery info via Battery History, my phones been running 20.9%. with the screen on 13.6%. I'm now down to 85% battery.

By the time I get home tonight after using the phone probably mildy at lunch time and tea break, I reckon I'll be lucky if I've 40% left.

I can I think go for a full day without a charge, but I would be really hampering my usage. I use the black wallpaper as well to conserve battery.

I just can't see how any of you people can be getting spectacular battery life...

I can't imagine how long it would take the battery to run down listening to MP3s for a good few hours. Maybe need to do a test...
[Desire General] andycted:
Mp3 playing with headphones doesn't consume a lot of battery to the best of my knowledge. Anyway you might have something wrong like the calendar problem already mentioned. I've also heard that battery plotting applications drain battery somewhat.

As said above, my battery wasn't holding a lot of charge for the first week, now it's really good, although lately with the super-sunny days we are having it lasts a bit less for the maxed out brightness. Still can't complain, I really have to hammer it in order to empty before the day has ended.
[Desire General] subharmonic:
Ah - so maybe dithc the plotter then?

I have never synced flickr - I don't appear to have any calendar issues.

I don't have screen brightness on full or auto (I use Power Widget to toggle screen brightness).

I'll uninstal the plotter - see what happens.

FWIW when I got home last night, I had about 20% left (I was listening to a podcast on way home for approx 1 hr).

Just now, I've just dipped under 50% from this morning...
[Desire General] philje123:
Am I the only one that thinks the battery life is actually good on the desire?!

I have only had it 5 days now and have had WiFi on constantly through the day and at night. Also text like crazy and a couple of calls a day with some internet usage and installing apps etc. I also play music over a bluetooth headset for around 2 hours a day.

I still have around 30% battery by the end of the day.

Compared to my G1 where 30 mins of WiFi would drain about 30% of the battery straight away.

I also have live wallpapers enabled (a light coloured one with little fishes) and have contacts to sync once a day and weather every 6 hours.

[Desire General] bananapie:
I also think the battery life is pretty good:D

On a normal day i usually have about 20%-30% left after some call, texts, videos and games with the nexus live wallpaper :D
[Desire General] andycted:
After a couple of days of 'monitoring' battery usage I think apart from the obvious browsing/3G or playing games, very high brightness is the main reason I can't get two full days of battery, meaning that there is a lot of difference between days with a full sun and cloudy ones (on auto-brightness).

This feels relatively different to my old LCD touch hd where brightness had a lower impact I think.

So, yes, I'm happy with the battery too ! Now the only part of the hardware I'm not sure about is call quality...recently I've noticed quite some hissing when calling abroad which isn't present with my other device

[Desire General] fboy:
Well I've read all I can on this issue in this forum and nothing has helped me resolve this.. My phone uptime and awake time are always exactly the same. When I look at battery use it always seem to be the Android OS that is taking up the majority of the battery. I have disabled as many services and closed as many apps as I can but even when it goes to sleep mode, the awake time is not affected. It's driving me nuts!
[Desire General] gleepface:
Do you have swype? Some people have said that causes issues and comes up under android OS
[Desire General] cosmicharade:
Try *#*#4636#*#* - that will give you more information - you can see under 'partial wake' if any application is preventing the phone from sleeping. I had a problem with Playlist Alarm. Battery improved dramatically after I removed it, although I had never used the application, go figure.
