Looking for proven and tested higher capacity battery for HTC Desire

As above, anyone using higher capacity battery for their HTC Desire and it is tested and proven to last longer than the original batter? Can post the link to purchase the battery?
Thanks!

Before you buy another battery, have you read this thread about calibrating your battery?

And have you installed a rom that allows underclocking? It makes a massive difference.
I am now getting 20+ hours from my phone where as before underclocking I was getting 8 hours.
Same amount of usage, just underclocking when screen is off.

Erm.. I will go read about it, but because I want to retain as it is now, thats why I'm looking for an extended battery.

What kind of battery life do you currently get? Before (accidentally) calibrating my battery I was getting around 10-12 hours, now I'm getting around 36-42 hours.

I'm looking for one that can last me more than 1 day.

Well, I'm using the standard battery and have 26% remaining with "1d 10h" since unplugged (admittedly I haven't used the phone for that much in that time, just some internet usage, a couple of calls, but it's been constantly on WiFi or 3G to sync GMail).

Use SetCPU for underclocking, and use JuiceDefender to automatically turn off your data connection while the screen's off/locked.
It will still reconnect every 15 minutes to sync, and will remain connected as long as there's any continuing 3G traffic while the screen's off. Basically what it means is you're running one of the most power-consuming parts of your device only 1/15th of the time, which make a big difference. Text messages and voice calls come through instantly still - only things requiring a data connection like facebook, weather, twitter, etc will have any delay, and even then it'll only be 15 minutes at the most.
You can also try setting your phone to WCDMA-only, which means it won't be constantly trying to connect and maintain two radios simultaneously. GSM-only would be even better but depending on your carrier it might not work at all or might only work for voice.
With SetCPU try making a profile to automatically go into "powersave" mode when the screen's off, which will ensure the CPU never clocks up past its minimum speed during that time. It's still over 200 mhz, more than enough for anything you might want to do in the background. For normal operation, between 499 and 768 mhz as the maximum clock, depending on your preference, should be adequate and will save you a little bit of battery life as well all the time.
Also, download a widget to allow you to manually set screen brightness when you're indoors and the auto setting is useless. I have my screen brightness set to 15% while indoors and it's still plenty bright. I have the SLCD model, I don't know if that makes any difference.
My phone has been off the charger for 17 hours and 10 minutes. During that time, the screen was on for 2 hours and 29 minutes. I'm at 79% battery life with the standard battery.

Yours able to charge it properly?

A small update to my previous post... I'm now at 32 hours, 38 minutes uptime, 4 hours 44 minutes awake time (screen on). Battery just reached 60 percent. Stock battery.
Remember when you made the choice to buy an Android, you were in effect saying you wanted to have a highly customizable miniature computer. Just like when you customize [insert your desktop OS of choice] to suit your taste, you need to configure your phone in order to get what you want out of it - namely, better battery life than with the standard settings.
HTC's goal with the Desire was to have a showpiece, it runs very fast and it looks good doing it. But they designed it with frequent charging in mind. Since most of us here, I imagine, would prefer to charge less often, we just need to configure the phone appropriately.
If you want a guaranteed solution, try this:
- Install NextSense rom (it's free, latest version right now is 5.3 AFAIK, I'm currently using 5.2 still)
- Install JuiceDefender - it's free on the market and its default settings are, for a change, very intelligent and effective.
- Install SetCPU - You can get it free on this forum. Set it to "interactive" mode with a bottom speed of 245 and a top speed of 806 to start with. The default is 998 at the top, but 200 mhz doesn't make a big difference in this case except to help battery life a bit. Once installed, add a profile for "screen off" which sets the phone to "powersave" mode. This will keep it running at the minimum clock any time you're not using it. Nothing running in the background while you're not even using the phone requires more than the minimum CPU speed.
- Install the Brightness Widget by Curvefish. It's free on the market. Put its widget on your desktop and keep your screen brightness at 25% while you're indoors. 15% is what I use, but 25% is one of the presets so it's a bit easier. I have an SLCD display so the brightness I get on auto might just be different from what OLED gets on auto, I don't know, but in any case for me it's way brighter than it needs to be.
- Set your screen timeout to no more than 2 minutes
- Make sure any apps that sync data do so in a reasonable interval. +/- 15 minutes won't ruin your day for most things.
- Under Wireless & Networks, set your phone's connection to WCDMA-only (3G-only). For many people this results in an increase to both signal quality and battery life, since it allows your phone to only run one radio at a time, making a significant difference. If it doesn't work for you, it's as simple as turning it back to the default setting.
- Disable haptic feedback and see if you mind the difference. Making all those little vibrations takes power too.
- Finally (obviously) don't run a live background, but you probably already know that.
Doing all of the above takes an hour or maybe two at most to set up and the difference in battery life is tremendous. It's simple to do, I worked out all of the above on my own and I've literally only had the phone for 4 days now I think, never touched a smartphone before in my life let alone an Android.
Give it a try, you have nothing to lose, and it will probably save you needing to buy a battery. Or, if you still buy a double-capacity battery, it'll mean you can run for like a week on a charge.
edit: also make sure to get the latest version of the radio driver, I don't have a frame of reference for comparison since I updated mine right away, but apparently it makes a fair bit of difference and probably gives you a more reliable cell signal in the process.
In case you think I'm exaggerating, here are some pics I just took.

"Ideal" settings are basically the way it's configured by default. You can't improve upon them much even by getting the "premium" upgrade unless your phone is rooted... but SetCPU is a better choice in that case anyway.
Just install it, hit "enable" after it's done auto-detecting your phone's capabilities, and you're done. It's really that simple.
Be sure to add it to your task killer exclusion list if you use one.

You saying the default option is for SetCPU or Juicedefender?
So just download the free juicedefender is good enough for me already since the pro version is more for rooted phones? (mine is not rooted)

Yes exactly. The pro version unlocks some more customization but ultimately won't add a whole lot to your battery life no matter how it's set up. I mean, beyond what the "regular" version does.

What apps are you using? Juice Defender? Set CPU?

I am coming over from the sd version of android on my HD2. I had to download all sorts of stuff to get it working correctly. I already found Set CPU does not work correctly. Has anyone tried SD Card Increase or Juice Defender. Are these things needed?
I read the speed up apps thread but was wondering about these apps in particular.
Is there a way to regulate the CPU to save battery?
Edit:The latest version of SetCPU seems to work fine. I think I had an old version.
I am also using Antek App Manager to freeze battery hogs like wifi calling.
Where's my Droid Power is another helpful app to isolate what is killing the battery.

Anyone try a screen off profile with setcpu yet?
Sent from my G2x

Setcpu wont work until kernel allows it.
G2X

SetCPU works at the driver lvl. The Nvidia tegra 2 option is there to pick when you 1st load the app. You can set profiles as well. you just can not control the scaling yet. You can control how the cpu runs

Running SetCPU and it works fine for setting profiles and helping to give ya a bit better battery life.
I'm also using juice defender and power manager. With them and my profiles set up similar to what I had on my Nexus One I am getting really good battery life.
I got over 24hrs (closer to 36 actually) on my last charge, but my usage wasnt too heavy, but close to average for me.

I've got a profile set-up for "screen off" through SetCPU along with using Juice Defender running all the time. I also used Bloat Freeze to stop the random stuff from even starting to cause drain.

I was curious about what kind of profiles/set up you had for these 3 applications: Setcpu + juice defender + power manager. Perhaps you can prepare a guide for us. It would be greatly appreciated =)

Last cycle I did, I got 25 hours on a single charge. This is exactly what I'm doing. First, root. Next, set up sync so that it only syncs apps when you are using them, as there is a problem with the 4g handoff to Wi-fi that seriously messes with battery life. Set Wi-fi sleep policy to never, so 4g doesn't interfere with it. Set device to use 2g network only, you might get better reception. If you need a fast connection, just enable it real quick. There are widgets you can use to switch it back and forth quickly. When rooted, use root explorer or bloat freezer to get rid of/freeze ALL T-mobile apps. These things always use data, even when Wi-Fi is available. Since they start on their own, you will always have 4g on, sucking your battery dry (and your wallet if you don't have unlimited data). I've also heard updating the apps works, if you are planning on keeping stock ROM. Keep brightness to its lowest setting unless you need it higher for whatever reason. This setup might seem extreme, but i've been on the internet since 6 am, playing need for speed shift, watching youtube, listening to music and I'm at 65%.
Factory reset and do the google setup immediately. For whatever reason, this is important. Let the battery run dry for the first week or so, and then charge it all night.
Above all, remember that the battery stats on this device are ALL CRAP.

Read this post, beautifully explained.
Good luck!

Though far less sophisticated, I like Superpower the best. It very simply and efficiently disables data/wifi when the screen is off, which is all I need.

Thank you for taking the time to write that up. Definitely will give this a shot soon enough.

Sorry for the slow reply, had a deadline beating down on me.
For the most part I just set up several profiles in set CPU and also profiles on power manager, and I just use the basic settings on juice defender.
SetCPU profiles I have are:
Screen Off 760max/216min
Battery<25% 816/456
Battery<15% 608/312
Hope that help some. Mine seems to be averaging about 18-20 hrs per charge now, but I find myself messing with it quite a bit I think once I get back to my normal usage, like my usage on my N1, it will easily make it 24hrs with a charge.

preview versions of Riptide GP, Pinball HD, and of course some Angry Birds or another - gotta catch em all!
That reminds me - why hasn't nintendo released PokeMon for any system other than their little nintendo handhelds? Seems like an untapped market.

Cant get setcpu to work. Force closes on me. What did you guys do?
Sent from my LG-P999 using XDA Premium App

does anyone else use setcpu on the g2x

in the pursuit of an everlasting battery, i installed setcpu on my phone yesterday-- i set it to a max of 400 when the screen is off, 800 when overheating, 700 when at 75% of battery, 500 when at 50%, normal when ac charing and 70% when usb charging (so i can hopefully charge faster in the car).
i havent been an android user for awhile and dont know if setcpu is one of those programs that use more battery than it saves i.e. "bloated". also, i know it sort of defeats the purpose of the dual core to underclock, but i'm going to be honest, i'm an iming, texting, browsing, sync two emails, words with friends, shopkick kind of gal...

ewww Words with Friends. WordFeud FTW!
I have never messed with SetCPU aside on my Android tablet because it had a problem sleeping. I can say that it did wonders for my tablet, I can't see why it wouldn't be the same in this case.
I don't know if I would set it to vary the speeds based on the battery readings. My tablet I had the CPU set to like "72mhz" when the screen was off and On Demand when the screen was on.
I also used Advanced Task Killer to kill all tasks when the screen was shut off because my son was launching games and leaving them run in the background. Between the two, the unit was like a whole other unit. That might be overkill but if you are worried about saving battery, might as well kill all those background apps too. Wouldn't hurt to test it. My biggest concern would be your Email Sync and IMing.
So in Advanced Task Killer, just have it ignore said apps and kill everything else.

yes i have am using it on my G2X i only have a screen off profile which is set at 216-312. I dont really want to lose speed just because my battery is low and while charging the phone doesn't heat up like my N1 did so i don't see a need for a profile there. It does work and it does work well.

hey! theres nothing wrong with wwf.. :]
i froze many bloat apps with titanium, and games too since i'm not much of a gamer :/ yeah, iw as thinking of taking off the syncing and iming, but i get very aggressive and could see myself dumbing down my smartphone for the sake of the battery.
with setcpu the way i described, i have noticed a loss of 5.5% an hour with normal use during the workday-- which is when i need to save my battery since i cant charge at work... i think i can live with 6% an hour... maybe.
but i did like underclocking for certain temperatures, because for some reason the phone is feeling hot in my pocket and has temps of about 91

Advanced task killer? Why am I hearing it's bad for your phone? Even when I installed it, I was losing a lot, even with Juice defender I'm losing a lot. I hardly have any apps, and I'm afraid to use my phone because of my battery.
Anyone know what I can do?

Once undervolted kernels start rolling out, battery life should improve marginally.

SetCPU

I've always read in the past that the app doesnt actually help with battery life because its purpose was for OCing and Android regulates the cpu clocks already.
So I'm wondering, for those currently using it, have you noticed any difference in battery life (without underclocking while in use)? and if so what profiles are you using?

I have just one profile, screen off= 216/216. I'm now on 14 hours with 30% left. Much better than before, when I was getting 11 hours at the most.
I also use the battery calibration app. But that's all I've done.
Just want to add I use wifi calling, and I run everything else, gps and syncing gmail and facebook is on. Screen is set to auto brightness. The only thing I have off is bluetooth.

Android does regulate the cpu, but I don't think it will take advantage of more conservative governor modes unless you tell it to. That's only relevant if the kernel supports more conservative governor modes. And, as the other responses have pointed out, you can force Android to be more conservative by capping the max clock speed.

Hmm... Guess its worth a shot. Good lookin out guys.

when i go into setcpu there are alot of options to choose there is no auto detect like on my mytouch 4g. how did you guys get it to work. i picked the last option which was custom and it forced close on me.

I think that that means that the kernel is not supported for the "automatic" governors. However, you can still create profiles to regulate the CPU based on perameters that you set, i.e. Screen off 216/216

So all G2x see the same in setcpu - no autodetect and only governor available is "driver"?
Will custom ROMs like CM7 change this?

SetCPU improved my battery life tremendously! Before I was losing about 15-30% and hour, since 8:30 this morning my battery only dropped to 73%. I set my active profile between 457mhz and 816mhz depending on remaining battery and it's still fast as hell.

Once we get some custom kernels, we should be able to change the governors in setCPU, dependent upon on what the kernel supports.

SetCPU Custom Frequencies for G2X
I got SetCPU today and was playing around with it and it looked like it was limiting my CPU all the time due to lack of profile, not just when I had the screen off per my profile so I looked into making a text file for custom frequencies and am posting it here since there doesn't seem to be any help for g2x with it.
This is a really simple file, tell me if you guys have any better ideas, I just put in:
216000,528000,712400,1000000
I'm attaching it. I put the file in my dropbox, grabbed it via the app and then moved it to /sdcard/setcpu.txt via astro file manager then loaded custom profile from within setcpu. Hopefully this saves someone some time or you can tell me if I'm going about this the wrong way
I'm sure it could be fine tuned more but I was getting irritated at how much of a pain it was to unlock the phone with it set too low, so for screen off I have it set to 216->528. You could add 254000 in or something. The phone seems to be as usable as before now with setcpu enabled like this while it should be limiting the cpu when the screen is off. It sucked (well not the battery) without a custom profile.

Actually, your assumption is wrong, as is often the case.
I'd quantify it more as normal use. Lots of texts, some games of Pro pool, a few phone calls, checking Pulse 3-4 times during the day for 10 minutes at a time, some mild web browsing and watching a few youtube videos.
I ended up at around 18-19 hours of of use.
Today, I'm off the charger for 8 hours, and I still have 45% left, and I would say that's with some moderate to heavy use.

Try upping it to 216/312 or a tad higher and you should be fine.

[How-To]Getting Better Battery Life

This is what I've done to help my battery life.
Firstly you'll have to root your device, then follow the steps below.
1. Install SetCPU(from Market or where ever you can find it)
2. Run it, allowing root access when asked by superuser.
3. On the Main tab, set Max and Min to 1200000(1.2Ghz), or whatever you want general usage to be. Most users probably want it like this so it will stay at best performance during using, and will not slow down. Also, whatever speed you're using set Scaling to Performance. Even if you are not running at top speed, it is still good to use Performance for the settings you want while using the device.
4. Go to Profiles tab. and check Enable, and click Add Profile. Set it to Screen Off, and you can change the settings to whatever you want. I had it at 100000(.1Ghz) for Min and Max, but when you go to unlock your screen, it lags a lot for a second. I currently have Max and Min set to 400000(.4GHz), and it made it so it does not lag when I go to unlock, but it is still low enough to be very conservative on battery. Set Scaling to Powersave, and Priority does not matter unless you have more than one profile, so don't worry about it.
5. (Optional) Install JuicePlotter from the Market, for free, and it has a nice widget that collects your phone data and after a few days will become very accurate on phone battery life remaining. It will show it after a day or so, but it will tell you how accurate it is, and it might not be very high until a few days later.
And that's it. Whenever your screen is off, it will underclock the processor so it's not using as much battery when not necessary. If you want, you can add other profiles, such as for when charging, and when the battery is low. I originally had it set to 1.2 GHz Max and Min while charging, and set the priority higher than the Screen Off, so it didn't clock down if I turned the screen off while charging, but there is no reason, I'm still not using it when I turn off the screen, so I deleted that profile.
So if your only profile is the Screen Off, then once you turn the screen on, it will change to whatever settings you have on the Main tab.
I unplugged my phone at 6:30 AM, and it is now 5:30 PM here, and I still have 32% battery, with JuicePlotter telling me I have 4 hours and 49 min left, but it only has a 72% accuracy since I just got the app yesterday. That's great since yesterday my phone would have been dead over 2 hours ago. When I woke up JuicePlotter said I had around 15 hours, but it wasn't as accurate as it is now, and it so far is expected to last longer than that..

I just use JuiceDefender free set to Agressive to obtain the best battery life. I got this little vendetta against SetCPU though.

I saw a button on there that said battery saver, what exactly does it do?

It takes you to a recommended battery saving app from the market. I haven't tried that app, but I imagine it is probably something similar to SetCPU.

I think this is wholly unnecessary, I'm sure samsung underclocks when not in use already, it's an obvious thing to do. I haven't done any of this and I can get ~40 hours of light-medium use

But try watching justin.tv streaming movie on hspa+ lets see if you even get 4hrs?
