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.

What's the ideal settings for juice defender? Cos my phone is not rooted so I'm not going to use the SetCPU application.

What do you mean charge properly ??

"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)

Can somebody pls. post the link to SetCPU?

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 =)
My device gets me 10 hours, I am very interested on how you are getting 24+ hours.

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.

Definative guide on how to get amazing battery life

1.Reduce display brightness of your screen
Although Samsung Galaxy S come with Super AMOLED which is supposedly to reduce your battery consumption but ironically it is one of the biggest battery life eater of your phone. Try to disable Automatic brightness and set it to the lowest level will improve your battery life a lot.
2. Remove unused widget in the menu
You must always remember that the more widget you have, the more battery life will be consumed up especially those widgets that use data connection and auto sync based on schedule. PS: only keep those widgets that you really need.
3.4. Turn off Bluetooth, GPS when idle
Only turn on Bluetooth and GPS when you need it, otherwise please disable it as it will consume your battery resources. Or please ensure that the charger is hook on your device when you turn on the GPS in the car.
5. Turn off 3G data connection, use Wi-Fi instead
Always gets connected with Wi-Fi when available. 3G data connection consume more battery compare to Wi-Fi connection. Turn off both of them when not needed.
6. Ensure you phone have a good signal as poor signal consume more battery life
When the phone is at the poor receiving end it will tend to use more power than usual to increase its signal strength with the communication tower. So it is always good to make sure that your phone has a good signal reception. You can try to switch to 2G if 3G connection signal in your area is poor.
7. Try to disable / reduce auto-sync whenever possible
All you have learned, data connection does consume lot of your battery life. By disabling the background scheduled auto-sync applications like Facebook, Gmail and Twitter can save your phone lot deal of battery life. If you really have to turn on the auto-sync feature in the phone try to reduce the frequency of auto-sync will also help to improve your phone battery life.
8. Disable new Samsung Apps notification
You can turn off new Samsung Apps notification if you not using it.
The configuration can be access through ~ >Settings >Application > Samsung Apps > Off
9. Turn off motion sensor
Only enable the Samsung Galaxy S Motion features that you using and try to disable those you not using like turn over, tilt, panning and double tap, turn them off as it might save your some battery life.
10. Use solid black static wallpaper and no live wallpaper
Most of the phone including Samsung Galaxy S Super AMOLED will tend to use less power on just solid black wallpaper than a lively solid white color based wallpaper because there will be almost no backlight on the screen. Please do bear in mind that a lovely animation live wallpaper will even cost you more battery life as ~ CPU power = battery life.
11. Fully close application that not use
Samsung Galaxy S is a super multitasking mini computer that come with dual-core processor but running a lot of applications at the background can actually increase your battery usage because they all require your phone CPU processing power. So it is advisable to fully close all the background applications that you not needed.
12. Freeze unused bundle applications
Too many original bundle software running in your Samsung Galaxy S? Freeze them… Titanium Backup Pro provide a way for you to freeze away all the stock application like Social Hub, Email, Maps that are running and utilizing your phone processing power even when you’r not using them. Ps: Your phone need to be rooted before you can use the Titanium Backup Pro.
13. Undervolt and underclock You 800Mhz GHz CPU
Aside from display, Samsung Galaxy S′s powerful CPU is one of the reason why your battery life eat up so fast. You can just underclock and undervolt it with SetCPU if you don’t need that much of processing power. Ps: Your phone need to be rooted before you can use the SetCPU.
14.Download and install JuiceDefender
With an amazingly over 5,000,000 downloads recorded so far in the Android market, JuiceDefender will definately extend your the battery life of your Samsung Galaxy S. JuiceDefender pack with powerful and easy to use power manager app that specifically designed to extend the battery life of your Android device. It can automatically and transparently manages the utilisation of your S battery like when to enable and disable the 3G/4G connectivity and WiFi.
JuiceDefender is available in the Android Market for free and if you would like to have a more powerful (customisable) version you can download the add-on JuiceDefender Ultimate for a small fee of $6.83.
15. Use custom ROM / firmware
Custom ROM / firmware offer a lot of optimization and tweaks to improve the performance of your battery life. You can try it out if you feel that after you have tried out all the tips above and your battery still draining too fast. But please be reminded that flashing a custom ROM / firmware will be voiding the warranty provided by Samsung.
Please let me know if there are other tips and tweaks to improve battery life of Samsung Galaxy S/Cappy that I have missed out.

I think #14 is not necessary if you are running a custom ROM

why wouldnt it be?

I believe number 11 has been proven untrue in the fact that killing tasks that the phone will reopen soon after actually reduces battery life hence the reason task killers are bad. Also the captivate only has a single core processor.
Other than that nice work it should help people out.

If you use a stock ROM with no voodoo color built into the kernel, then use full brightness, I do and I get great battery life, the screen isn't the biggest battery life sucker.... this isn't the greatest battery saving thread from what I can see.
Sent from my SGH-I897 using xda premium

Generally good tips, but definitely a few holes here and there.
For example, GPS doesn't drain when 'on', only when certain apps use it, making it pretty safe to keep toggled on all the time.
You can go further with SetCPU and other similar apps but underclocking during screen off, and I think that's helping me save battery in my personal experience.
Having a black wallpaper is good and all, but I feel that doing that is a bit too far in optimizing battery life. What's the point of having a pretty decent screen when all you do is use a black wallpaper?

Or flash Darky rom 10.2 Extreme Edition.

That is no good, considering the screen should be taking most of the power.
You either arent using your phone or you are crushing batteries in hours.

No I'm using it, Android OS process in ICS includes more than what they do in GB. It last all day (~15 hours with %40 left)
Sent from my SGH-I897 using xda premium

Yeah I have the ICS port, build three, and the battery sucked the first day due to all the downloading and cpu usage, but after that and a full charge and battery diagnostic wipe it was a great life with decent usage on apps and data and messaging with auto brightness

In Point 11, Captivate uses single processor....and killing system apps causes more battery drains....

My limited experience with roms suggests that as roms are works-in-progress their battery life can vary widely. Serenity6.1 has really seemed to be a long life rom.

These steps do make a big difference, also the Beta 2 build for ICS solves a lot of issues that users had with ICS battery life. Honestly if you want even more battery life grab the 3500 mah extended battery off amazon for $10.

15. Use custom ROM / firmware
Custom ROM / firmware offer a lot of optimization and tweaks to improve the performance of your battery life. You can try it out if you feel that after you have tried out all the tips above and your battery still draining too fast. But please be reminded that flashing a custom ROM / firmware will be voiding the warranty provided by Samsung.
Please let me know if there are other tips and tweaks to improve battery life of Samsung Galaxy S/Cappy that I have missed out.

Basically dont use your smartphone as a smartphone. Thats what you're saying by turning off all the good features of the phone.

1, 3, 4, 11 are like NO DUH!!!
5. Are you saying use EDGE? It will save some battery, but you have to consider it may take longer to load something, and thus the screen might be on longer, negating savings. Plus, it's a PITA to change back and forth.
6. Other than switching to EDGE, not really in your control.
7. That's stupid. It defeats the whole purpose of having a smartphone.
9. As long as you lock orientation. I doubt it saves much though...
15. YES, that can be HUGE.

Having a black wallpaper is good and all, but I feel that doing that is a bit too far in optimizing battery life. What's the point of having a pretty decent screen when all you do is use a black wallpaper?

I agree. I think a compromise is a better idea. A lot of ROMs have black wallpapers with a small % of extremely brightly colored random or geometric designs, or green android-ish swirls or something that look AMAZING on the AMOLED screen.

Thank you all for your feedback.

Help getting the best battery life

What rom should I use and also what tweaks/scripts should I install to get the best battery life
Sent from my SCH-I535 using xda premium

Hard to answer without testing some roms for yourself....
Synergy Rom is a good start which eliminates bloat from the provider...and then optimize the rom. Add a better kernel over stock like Imo or Ziggy and that took controlling CPU power (depending on your setting) can help gain better battery life...mean over 8+ or 12+ hours of life

30+ hours with almost 4 hours of screen time : cm10

This isn't really a tweak or script, but turning off mobile data and using wifi helps a ton. Constantly searching for 3G or 4G connection is what kills my phone's battery.

Here is what helps me..
-turn off any data that doesn't need to be running in the background while you are using it i.e...gps, 4g, bluetooth. (Use "phone info" from the market to switch from 3g to 4g.

-make email manual push. when you have email set to constantly search for new incoming messages it can run down more than needed. if nothing else switch to every 15-30 min.
- turn off all notifications that you dont need to be notified about
-screen brightness will be a HUGE battery eater. I have mine set at 1% most of the day which really helps. this screen is bright enough to have it that low and still see well.
-download "widgetsoid x2" free. a fully customizable toggle bar which will allow for easy on off for items like bluetooth, gps, wifi and gives you a brightness option to customize 3 settings. I have mine set for 1, 25 and 45%
-use setcpu or another app alike to control cpu. create a profile for "screen off".I set my profile at 348x486. this drops the processor while screen is in sleep mode and will save battery life.
-I dont know how effective this is, but I heard it helps and makes sense. Choose a dark wallpaper. Having a bright, full white wallpaper takes more battery life to display.
As for ROM's, its hard to say. there are so many things to take into consideration when someone says they got 30 hours on a rom vs the next person who only gets 12 hours. how much are they using it, what do they have running inthe background...etc. I tried both bean and synergy and I prefer bean. He just released R6 yesterday and people seem to like it a lot. I personally prefer R2, his original release. It has been super solid and I have had better results from it over 3.1, V5 and his late R6. My buddy has had GREAT results with synergy, but I did not. I gave it a week and ended up restoring back to bean.

download BatterySaver app from market. My s3 runs 12-15 hours on "Intelligent Mode"

Honestly, you can only do so much with software tweaks. If you're a hardcore power user, I suggest getting an extra battery of a similar size (~2000mah) or getting an extended battery.
As for what you can do to save battery, the only thing I can think of that people haven't already mentioned is turning off animations. It can make things feel a bit choppy, but you'll get things done faster, which means less screen time.
