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.

The search for decent battery life.

I know I know that disabling data can get me 24-30+ hours of battery life. However for my on the go lifestyle, that's just not possible. I depend on my phone to keep my email updated. I have four email accounts (two of which are exchange) that sync calendars and contacts as well as email. I was using push on my two exchange accounts, but I've changed that to do every hour for one and every 15 minutes for the other. my other emails are set to check every hour. I have craigslist notifications set to check a single time per day. I have a weather widget that is only supposed to check every 4 hours.
I am running Perception 10.2 with the latest firebird 2 kernel, but have also tried various versions of speedmod's kernel. I have tried the following modems
JL1, JL2, JL3, JK4, KP1.
No matter what I cannot seem to get more then about 10 hours of battery life on standby ONLY. no phone calls, no turning the display on, nothing. I consistently get around 1 hour of time per 10% drain on my battery. I'm not asking for miracles. I just want my phone to be able to last at least 12 hours (a full work day plus drive time.)
I've already set the programs with the most spartan settings I am willing to use. I'd rather have my phone pushing data to my much more often, but I understand that's not going to be possible unless I can find a drastic increase in my battery life. What else can I do?

I have 3 email push accounts, and google voice syncing all the time. Email includes emails with attachments too, and EDGE is pretty much sufficient for most of these things. Even for normal day to day activities like browsing XDA, EDGE is pretty much sufficient.
So I would advise u to switch from 3G to EDGE. U can turn on 3G when u need more bandwidth demanding apps. This would reduce some strain on ur battery.
Only downside would be that u can't browse n talk on phone at the same time. But its ok by me to get a few mails after the call I am on is over. I can live with this small inconvinience in leiu of the additional battery gain.
As of this minute, with the configuration I have in my signature (am using xcal kernel), I have like 63% battery left after ~7.15 hours standby, with 1h31m of display on and 40m of calls, alongside mails being pushed.
Edit: At the end of my 'normal' day with 'moderate' usage (1-1.5 hours calls and 1.5-2 hour display being on (not for games/movies, but with active data transfer on like texting), I reach home with ~50-60% battery left.
On a side note: I would recommend to turn off updates in weather widget, and use a manual refresh when needed.

how do you easily toggle between 2G/3G? it's my understanding you have to use service menus to access the change.

If u r on the ROM I am using, u can get it in network settings.
Some 2.2.1 ROMs do not have it in network settings. If ur ROM doesn't have it, u would need to access through the service mode code "*#*#197328640#*#*.
When in service mode, here is the sequence to select in the options:
option 1
option 8
option 4
option 3
Note: Pressing 'back' key will NOT take u back. It will close the service menu. Press the 'menu' key, and select 'back' to go back.
Be warned, this would not stick on reboot. U would need to repeat these steps whenever u reboot.
Alternately, I would suggest u move to a ROM that supports EDGE/3G switch. If the ROM supports this option in network settings, it would stick on rebooting too.

Yeah, I just found that. Perception supports switching, but you have to go to the settings menu to do it. I found something called Juice defender, and will play around with that as well. Unfortunately we aren't on an ASOP build, so we can't auto toggle 2G/3G, have to do it from the menu. I will report and let you know what I find!

Sure. By the way, I don't use any apps like juice defender. Realized that my battery is well off without them by taking care of little things like turning off wifi and bluetooth when not using them (well, these are the only two things I take care of manually).

I would normally agree with you, but as I was looking through the app I saw that it actually disables data while the phone is off, and only turns it on temporarily at intervals to allow application updates. If it truly works just like it states, I could have essentially a battery experience similar to turning off data while still enjoying my notifications. More experimentation is necessary.

Juice Defender gives me 60 to 70 % more battery life. I have it set to sync every 15min and wifi is location based.

Yeah, Juice Defender works absolute wonders! it gives me the same amount of battery savings that switching to 2G gave me, but automatically enables and disables itself when I need it. I'm on 70% battery left with over 7 hours off the charger, and that was taking voice calls and doing some light email checking!

Try a kernel that supports OC/UV. You don't have to overclock, but undervolting is what you want. Check out Suckerpunch kernel. Nice guide by shaolin. Can't argue against a black belt. lol.

Unless I can only have it underclock while I'm not using it, I think I'll pass. I bought the Captivate for it's 1GHz proc, if I wanted something slower I would have gotten the aria.

You misunderstand. It's undervolt. That means use less power at different processing states.

you can undervolt a proc without underclocking it? How is this possible, unless they changed the FSB or timings on the chip?

I pretty sure you can use voltage control and set highest state at 1000mhz and set lower voltages for states below it. That's as techincal I'm going to get.

By running the chip slightly out of spec.
You can usually undervolt each cpu step by 50 to 150 mV. How to find the right point really does just take trial and error. And as with all overclocking/underclocking your mileage may vary. Some phones can really be pushed to the limits and run fine, others don't like even the slightest changes to the stock settings. All depends on how well your phone was put together, and from where in the wafer your CPU was taken from.
Undervolting can save you a fair bit of battery though. Won't help a whole lot when you're actually using the phone (since the screen and 3G/WiFi radios will suck way more power than the CPU), but it will help seriously increase your standby time.
PS While undervolting and overclocking capable kernels tend to be one and the same (since the underlying code is related) you DO NOT need to overclock your phone to undervolt the CPU. You can run your CPU at stock 1 GHz while still undervolting each frequency step. Course, with some tweaking and good luck, you can even get your phone to run at 1.2 or 1.3 GHz while still using no more power than a stock phone at 1 GHz.

How much battery gets used when the phone constantly switches between EDGE and 3G? I'm curious because my building has thick walls and my 3G signal constantly drops down to EDGE when I pick it up, then goes back to 3G when I leave it sitting out on my desk.

Any time your phone is forced to switch from 3G to Edge, or even from one band to another, it's not a good sign for your battery. Exactly how much power difference? Grab a multimeter and hook it up between your phone and battery. Record some data, and test for statistical significance. And let us all know.
Short of that, I'd say if you spend a lot of your day in an area with known bad coverage, I would hop into the engineering mode (*#*#0011#*#*), and lock your phone to a specific band and radio mode. Like 850 MHz EDGE, or 850 MHz W-CDMA. Or if you are in an 1900 area, then 1900 EDGE/W-CDMA. Not just EDGE or 3G mode, but a specific band AND radio mode. You need to be smart, and pick the band that has the best coverage so you don't make life even harder on your radio, but it can save some battery life over the phone jumping around ever time you walk from one side of the room to the other.

i running paragon 5.1 rom with the 1280mhz kernel overclocked to 1280 and undervolted. my phone has been unplugged since 7:30 am eastern time it is now 8:04 pm eastern and i have 73% battery left lol. i have done everything today on the web screwing around with my phone. the best rom so far and im even overclocked.

Fyretech rom with imoseyon kernel 1.92 dialed down to 1.792, setcpu, atk. Today is the first day running this combo phone has been on since 7am, moderate use (phone calls, texts, games, internet and youtube,) its 10pm now and i have 39% left on battery. I would have had to charge my phone at least once today when it was new out of the box.
EDIT: using 3g, 4g not available yet in central Jersey.

I'm using the bamf v4.3a kernel with the stock rom. i'm also using setcpu set for the 'ondemand' governor and a profile that underclocks the cpu to 245/245mhz when the screen is off.

BAMF 1.4 sense remix, with adrenaline (spelling? 4.4.2 kernel, dark horse theme, auto rotate Rosie (Saweeeet!) Optimal setcpu settings. Ie: charging profile (245 mhz min- 1.0ghz max/smartass) with this setting I normally get almost 1% battery charge increase a minute. screen off profile (700's mghz-1ghz/on demand. Screen on profile (1.1ghz-1.3ish ghz/smartass. etc... I know some stuff I mentioned doesn't really pertain to battery life, but this set up is just sick! Also, I read somewhere that its a good idea to let ur battery die completely, then turn phone on without charging (you may have to just a bit to get it back on) And let die again. This supposedly tells the phone where the dead zone is on the battery accurately, so it can now get a full clean battery charge. Myth? Idk, but damnit my battery is sick now! Hope this helps.

Personally, I've been testing Imoseyon [ROM] Tesla Coil Version 1.5, with Imoseyon [Kernel] leanKernel: minimal kernel "battsaver" .92 version. I am running it on "On Damand" with charging and screen off profiles, mobile data NOT on auto sync, Tasker for wireless ON at Home and audio OFF at nite.
Really, this seemed to have doubled my battery life. I was having to charge before the end of the work day with moderate use and now have been able to use well into the night.
Hope to see even more Rom/kernel concoctions out there as I love to try any new suggestions.

With adrenalines (I still don't memorize the spelling! Lol) 4.4.2 kernel it deff charges waaay faster as stated. Setcpu charging profile to lowest mghz min to around 1ghz max on smartass. Not demand, n it will bounce around to proper mghz levels as needed to speed up charging process. Its sweet n like you, I'm open for more suggestions

Adryn's debloat ROM and his kernel, with extremely light usage I pulled 38 hours (my previous record was 36). I have been using my phone for the bare minimum, so this is why I got so high. No, this is not real world usage and yes, I hated it, but it works. My normal battery life is somewhere closer to ~18 hours, except on Tuesday's and Thursday's, when I have lecture classes, I usually pull 9-10 hours, because I play games and browse the internet for 2 and a half hours.

Using imoseyon kernel 1.4 extreme(InteractiveX governor) with Tesla Coil 1.5. I have an extended battery, and with moderate use my phone can easily make it through one day into the next before needing to be charged.

Screen off and plugged in.. ;-)

I think it would be best to post in your stats whether or not you have 4g enabled as there are large populations of each way and it makes a significant difference.

True...4g always enabled for me other then when I get no 4g signal and then 3g may go into effect. If no signal at all, then wireless when I am indoors.
I refuse to turn off 4g as that is why I got the phone and my coverage is pretty good for 4g...so, better battery life is a must for me

Go to settings, menu, wireless networks, mobile networks and uncheck the third box. No need to have mobile data always on for most peeps . You'll still have 4G n everything, but gain a good 1-2 maybe more hrs (depending on use, kernels, governor settings, and I/O scheduling. I personally am running BAMF 1.6.2 with adryns 4.4.7 kernel, no set CPU, using tool box for that at 245mhz min - 1.02max with ondemand governor and most importantly SIO Scheduler. Try these n you will have amazing performance and better battery life. Let me know you opinions

Best battery-safe rom at the moment

I've seen in the last months a lot of new roms and I can't try each one of them. So someone can help me to decide what is the best rom for battery life at the moment?
Now I've a defy with the stock froyo rom.
Thanks

i would suggest you http://forum.xda-developers.com/showthread.php?t=1285007 or walters msginger.both have good battery life
for performance cm7,miui,cmiui and the list can go
your choice

You will find that the stock froyo will nearly always have the better battery life than custom roms.

and when not using is it goes on for 3 or 4 days
Best battery in sleep mode

It depends mainly on 2G and 3G network or Automatically.
Only 2G saves lot of battery
Only 3G drains lot of battery
Automatic is in between. But it trys to hook towards 3G before it hooks to 2G.
Hence in any ROM... if you select only 2G, it will save lot of battery.
2G with manual network selection will still have a better battery.

Yeah barebones had the best battery for me but its not been updated for a bit now then Ms2g 2.1 (I personally love it ) but as mentioned above remember to change to 2G when you don't need internet.

I think the most batterylife gain you will get from undervolting for all ROMS. My settings are [email protected], [email protected], [email protected] stable as rock on WajkIUI 2.2.3

CM9 ICS Epsylon latest version.....endless battery

undervolting.... sometimes is a problem... if network signals are low ... the network radios need more battery voltage... if it cannot get more power... the defy hangs and has a FC.
Same with other apps which need a sudden power.

Main drain comes from 3g and constant connection to internet. Loose those two and you get 7 days at least.

cpu undervolt doesnt have anything to do with radios or anything else. It just affects cpu and maybe Bus speed.
The best battery savings come from turning off the radios, 2g only, automatticaly turn of wifi during data off-peak hours (if configured), screen brightness, and finnaly cpu undervolt. A full review of all of this is in my old post with the name "7 days of battery".

CM 10 performance settings

I just got upgraded from CM 9 stable to CM 10 stable and I love it. Only problem is battery life. I feel about a 10-15% reduction with the new upgrade. I've had CM 10 for about 4 days now. I don't want to touch the performance settings without knowing what I'm doing. Is there a way to change my performance settings to extend the battery life? Also has anybody played with a different kernel with CM 10 stable? Thanks

Don't worry about changing the cpu and governor settings. There is an option to set at boot. Make sure that is disabled, so if you have any problems a reboot will go back to default settings. I use the conservative governor, and have my minimum cpu speed set to 192. I've read that that speed is not entirely stable for many people, but seems to be working fine for me. That has been pretty good for battery life for me. I believe the default governor is interactive now, and the minimum cpu speed is set to 384 by default.

Do you just "feel" a battery difference, or do you have any actual numbers to back up that assertion? Keep a close eye on Settings / Battery and use Better Battery Stats to record solid numbers and identify what's actually eating your battery.

Also turn off google now location settings if ur not using it. They are really hard on the battery.

Disable Google now and battery should be back to normal here is some pics. Cm10 default kernel,stock clocks, no UV, on demand governed, and deadline as scheduler

Thanks for the replies.
It seems to be my screen that is responsible for eating up my battery. Have had the phone disconnected from the charger for 4 hours now and all I've done is 20 min with screen time doing a little bit of texting and facebook and my charge is at 75. I have the automatic brightness setting off and put my setting at pretty low.
The cell stand-by battery usage is 8% during these 4 hours. Should I maybe try another radio or is this normal? It lost signal for about 10 min today.
Just turned off google now and selected the conservative governor. Let's see if this makes a difference.
I used to be able to go all day with my phone with CM 9 and I even have the nexus battery.
Thank you for all your help

That's most definitely not normal, at least in my experience. Are you using the vanilla CM10 or some variant?
Some things to try:
Install Better Battery Stats (find the free version on XDA via a search) to see if any apps are causing wakelocks. This is a must.
Use CPU Spy or something similar to see if your phone is entering Deep Sleep. This is a must.
Turn off Google Now unless you actually use it
Turn off all unnecessary radios (WiFi, Bluetooth, GPS) unless you're actually using them
Turn off all auto-refresh settings in every app you have -- all social apps and weather are the biggies
For me, turning off the default auto-refresh in Facebook, Google+ and Twitter are massive savings alone, then Settings / Battery & BBS will help you locate the remainder of the headaches quite easily.
You might want to consider swapping kernels too, or at the very least reconsider your CPU governor and scheduler settings.

I would stay away from conservative governor you won't get much performance out of that, stick with what comes stock and use on demand.... even the default interactive sucks my battery down

I'm currently running the vanilla CM10
Turned off google now location access and set the govern to on demand early this morning and it is performing a little better most def.
I have noticed that my phone lost signal 4 times during the day for periods varying 5-10 min. I am currently on the I727UCLF6 radio. I'm thinking maybe I should try another one. Could that help with that battery maybe?
I have been thinking about switching kernels but I am a little doubtful because I don't want to mess up my phone too much since I so heavily depend on it. I loved the hotcakez kernel that came with AOCP, maybe i'll give it a shot this weekend.
Thanks for all the help people! Def the best forum by far on the web.

Just do a nandroid backup of the entire phone first before installing a new kernel and your risk drops to zero. If you install it and it all goes to hell, just boot back into recovery and restore your backup.
As for radio ... if you drop signal that often and your phone is constantly searching for one, I suppose that could impact the battery, sure. Are you certain you're in an area with solid coverage, though?

Yea I might have to play around with some kernels this weekend. Luckily it is a long weekend so I'll have some time if I mess up
My phone will go from 4 bars and a good signal at -78 dBM in my apartment and then randomly I'll lose signal for abut 5-10 minutes. A restart usually does the trick or I can just wait until it regains the signal which can be frustrating. I never had any problems with my signal at home running CM 10 so that leads me to think that there might be some problems with the radio.
Just want to confirm that these are the 5 radios I can use for AT&T even though I'm running JB.

I've been using a UCLI3 modem I found on XDA a couple of weeks ago, it has been incredibly stable and strong for me. But as many people far wiser than me have said elsewhere, everyone's mileage with radios varies and it really just takes some testing to see what works best for you.

so I should be able to run the 5 ICS radios I found eventho im running jb right?
thanks for your help
