I'm having the strangest problem with my HTC Evo...
I used to get over 22hrs of moderate use (rooted) and ever since flashing any ROM running Sense 3.0 my battery life is affected to the point I'm lucky to get 6 hours of use. It discharges 15% within the first 10 minutes after unplugging the charger and continues to discharge at an increased rate throughout the day.
I unrooted the phone and took it to Sprint to "test" and after 3 hours they gave me back the same exact phone claiming they had "updated" it and everything, including the battery, had tested perfectly fine.
I feel like they are giving me the run around because obviously something is wrong here.
Any ideas as to what is going on here?
Rooting doesn't improve battery life, never did. Think of rooting as gaining admin privileges to a Windows PC, for example.
I think you have a background process running that is taking up a lot of battery, check the Battery Use page or reboot the phone.
I know, but it shouldn't diminish it either. It does gives you a chance to see a potential increase by undervolting, underclocking, ect.
Anways, no background apps running. All display scaled down, GPS off, ect, ect.
I have no clue as to why this sudden decrease in life. And Sprint says the battery is testing "excellent" as is the phone. Obviously something is not right here. Feels like they are being lazy and trying to avoid giving me a replacement.
Evo is known for bad battery usage. Best thing for you to do is get a backup battery.
Lol. I know that too, I'm not new to the Evo. I work with phones, Evo included, on a daily basis at my place of employment.
I'm saying this same battery used to last over 22 hours with moderate use when the phone was rooted and underclocked. Now the phone drains the battery amost instantly.
I refuse to purchase an additional battery to combat a problem Sprint should be fixing. I paid over $500 for this phone and haven't even had it a whole year yet. Something else is going on here...
Sounds like a rom issue, not a hardware one. Those sense 3.0 features and eye candy come at a cost.
Yeah. Sense 3.0 is a battery hog. Try cm7 or something AOSP
ADR6300
yeah, one turne off and reboot, Battery Life TERRIBLE too, i'm lost 10% when reboot

It's ture ！
Have you tried an app that shows you battery usage over your running apps? May tell you which programs are stealing all the juice
!. Rooting does not have anything to do with battery life...well..not directly..it depends on your kernels, apps, phone settings, etc.
2. I agree, Sense 3.0 seems to drain your battery a bit more than previous Senses... well...you know what they say, beauty has its price..about the AOSPs, they have better battery live but they are not so pretty as the Senses...again...beauty has its price
If it helps the 'Live wallpapers' are known to eat battery, but what it could be is Wifi, if you leave it switched on all the time it may be connecting to open wifi networks without you realising and eating the battery.
Interestingly though, a whole day of use, some wifi a bit of camera and some calls on a wildfire with wifi on, didn't seem to drop the battery much and this is with a rooted phone.
you can try green power
Even though it may sound lame to some of you, the app Juice Defender has actually helped extending the life on battery quite nicely for me...
Another possible route might be to try different Radio/RIL combinations, some can also extend your battery life.
Not to forget, as someone posted previously things like live wallpapers or background process. Task Killers have been known to cause battery drain for instance.
Good luck in your quest for battery life!
Hans
if you go to battery use in settings, youd probably find out whats causing your battery drain
after i hard bricked my captivate im looking for new phone.
the main things i looking for is
-largest battery life
-3.5" screen
- working gps
im not playing games , i mostly using internet and listen to music on youtube.
any one can recommend me somthing ? O=
Root?
Are you willing to root the device? Many custom ROMS and kernels offer incredibly extended battery life. The processes are quite simple and laid out by developers in a step-by-step method for you.
Current I have a Samsung Vibrant 4g and am running a custom rom and kernel.
I can listen to Pandora from 8am to 12pm, texting and dicking around on the internet the whole time and am left with 50-60% battery life by 5pm.
If I don't use the phone at all it will last for about 2-3 days uncharged.
For tips all phone
Use Power control to close many thing ( wifi bluetooth GPS Sync )
and always kill all program.

Fongwe is correct.
Doesn't matter which phone you will use, you will always have complaints about the battery life, whether be it an Android Device or an i Device or a WP Device.
Since we are talking about a phone in Android section, I will say that so far out of all those Android phones I have tried/used, Incredible S has got the best battery life(This is strictly my personal opinion, I am saying everything based on my personal experience only.).
Next after Incredible S for me has been Atrix 4G.
After that I can say may be you will get decent battery life out of a Nexus S.
Don't get me wrong about Nexus S as a third place, it has got a decent battery life, the only problem is the 3G connection kills the power.
If you have background sync, bluetooth, 3G radio, wireless and too many applications running in the background all together, doesn't matter which phone you use, it will not give you a great battery experience regardless.
This is my typical usage from those recent phones. With about 2 hours phone call, few minutes of surfing, sync on constantly with 3G connection, play casual games for a few minutes and watch youtube for about 15 mins.
Incredible S - About 10 hours - Stock ROM
Atrix 4G - About 8-9 hours - Aura
Nexus S - About 6.5 hours - CM7 (May be my phone's battery is indeed defective)
If you are at work/home/on way, consider switching off your 3G radio and you will save up a lot of battery. Also, if you get a single core processor, it uses up less battery than a dual core phone.
Good luck.
Cheers!!!
Thanks for the information guys! will try these asap
Atrix has pretty good battery life. Atrix 2 should too.

You will always get the occasional answer on saving battery life and I think that constitutes for a big part of how you could really get a device that would last long.
I think that you should be efficient in switching applications, service and the phone itself off, if you want to have it last longer through the day.
Also, rooting it would be another good option but those who want to keep it as is, this would be no option.
New ROMs help
I have a Vibrant that I used about a year. I went through a lot of different ROMs/Kernels during that time. Battery life varied wildly based on overclocking, undervolting, open apps and apps used. Also, just like mentioned above, if you drive through areas where the phone is always searching for new connections it can have an effect on battery life as well. Pick a phone with good ratings that you like and keep the background apps to a minimum. Figure you will be charging every 1-2 days, 3 at the most.
Galaxy S II. Dualcore, used properly, saves battery.
I turned off GPS and Bluetooth on my Galaxy Captivate and the battery last 2 or 3 times longer. Turn off Wi-fi too, if you can live without it.

get a S2, root it and use and DEV's rom to your liking and flash a good kernel like speedmod or siyah
I finally decided I would take some extreme measures to aide the BL of my Androids. I have an HTC Inspire and HTC HD2 with Nexus S Android. The HD2 isn't all that bad...much better BL than the Inspire, but I wanted to apply this measure to both phones. Will it help? Only time will tell.
I started by removing all screen widgets. Then I sorted the screen icons so that a minimum of homescreens were needed...got it down to 2 homescreens. Then I deleted all widgets without apps not able to be opened through an icon. Then I went into Applications manager and cleared and stopped all non-used apps and services. I also deleted all duplicate services such as OEM email accounts and their associated syncing....using add-in apps for them. (example: built-in apps and widgets like Facebook, Twitter are uninstalled or disabled and am using another combining app like Seesmic. Same goes for the email app)
What I currently have is an Android iPhone. I'm using only icons on the 2 homescreens. And this makes me understand why Apple refuses to use widgets and stick with icons...to preserve BL. I hope this will improve the BL of my Androids because it is purely horrendous. And it is horrendous with all Androids I've tried and used.
Until the recently announced battery tech breakthrough is made available, this might have to be how Android is used from now on. But I doubt these extreme measures will actually help.
What is the difference between a widget and an application?
An application is a single, whole program package that is loaded into the phone. Examples would be Tapatalk, the default Calculator, and Angry Birds.
An application can have one or more widgets in it -- a widget is an interactive thing you can place on the home screen. It can give you information, and you can tap on it to change what it says. A good example of that would be Beautiful Widgets, or the little Android guy that tells you about how to use your new phone.

@Marty, how long was your battery lasting prior to the "Extreme Makeover"? Mine currently will last me 2 days. Admittedly, I've not loaded a lot of stuff on the phone yet, and I have the power saver mode start at 70%...but I only need to recharge every other day.
My desire lasts around 2 days with moderate usage. But on a good day (read: many boring moments), it's completely depleted by the end of the day. My biggest battery drainer is whatsapp, if I uninstall the app my battery will last a LOT longer.
If i really need my phone to last for a long time (when Im on a big trip or on a festival) I always use JuiceDefender with a very strict setting. This is a big help, but not for everyday use
whats the point? Where ever you sleep you have access to a plug/usb w/e so whats the big deal ? how hard is it to charge the phone every night? even thought my galaxy s2 hold battery for 40hrs+ i never need that :|
Ive dont the same thing, I also found some build prop and init.d tweaks that improve battery life.
my brightness is always at minimum, i have only one widget,
My battery could last two days BUT i use my phone a lot. like its on for 7 hours with 4.5 hrs screen on.

Hilarious.
ther have been many apps and disucssions on BL. heres some common tips.
screen to lowest brightness possible setting. background data always off unless using market. disable -use wireless networks- options, no gps, no location. also turn off *back up my data*. wifi always off not in use. screeen timeout no more than 2 minutes. turn off animations and transitions. setcpu with moderate settings (if you can do a screen off profile it will be beneficial but beware Sleep of Death.) no live wallpapers. minimum widgets or none. minimum homescreens or 1. startup manger. adfree. location cache app. and battery calibration to get the most juice.
the issues seems to be alot with hardware the Htc inspire and HD2 have 1250 Mah Batteries , which are very small.
If some people are just like me... I can kill at 1800mah battery in 5 hours even at full charge...
I do everything on my smartphone. So anything to save the battery is a good way.
I have the Galaxsy S II and I've managed to drain the battery in 6hours of usage and since I'm not near a power source most of the time then yeah I need all the juice....
I don't sit in an office or am near a power source 80% of the time. I usually carry 2 spare batteries with me and a charger for them just in case.
Cheers! (Extreme power user).

Whats the point??
Here is my daily usage :
Alarm goes off at 6:30am (phone gets unplugged)
Blahblah (at work) reply to emails and messages throughout the day, on twitter A LOT (plume premium)
2 calls approx 30 mins each
Play some games at break and lunchtime (Drag racing KILLS my battery, a bit of plants vs zombies, grave defence HD and maybe some pinball deluxe)
more emails and twitter
another 20min call
a little more gaming while im waiting on customers (1hr or so??)
6pm go home for 6:30pm
BAM! battery is at 10-20% and i need to plug it in again.
this is a typical 12hr day for me and im sure others have longer days and i would appreciate not having to rush home (sometimes) if im expecting a call.
so as far as im concerned anything which will save some precious battery on my devices is appreciated.
btw i have reduced my homescreens to 3 and only have 2 widgets running and that has made a great difference to my battery life (esp. on the DHD)

Basically kill factory and carrier bloatware and you are getting better.
One thing I was amazed about was the eBook reader that comes with our Galaxy Tabs, and suppose others too.. it always working even if you dont have or use it.
And remember, the screen is what takes most out of your BL, always. Lower brightness? Get a better ROM with no bloatware and maybe undervolt the screen.
Homescreens dont change a bit. Widgets do, if they update a lot.. more than that notification stuff do. Like if you use a antivirus or antisomething, just check of notifications.. check of any unneeded notifications.
Vibration theorically is what consumes the most.. but since its not as used as the screen, you dont even compare them. But every little bit helps. Check off keyboard clicks and hepatic feedback - vibrations.
Wifi, bluetooth, data... don't actually consume much.. actually it's better if you leave a service stable on, than keep sleeping and switching it. So leave wifi always on, no sleep policy. But when you go out turn it of so it doesnt keep scanning all the time (unless you want to ).
Just like any PC, the more you install.... Just check what you got going on, learn how to check processes and services that keep on all the time, and there are some utils to help stop some crap from starting up. I use ROM Toolbox and Autostarts.. some stuff get activated just because you plug you device to charge!
DONT use task killers... dont let anything like that keep running... and no, GMail push notifications wont use any batt. Maybe pop/imap emails always pollling will use some.. but probably nothing compared to the examples above.
Cheers for my 2 cents.
EDIT: and after Xmas, remove those animated wallpapers!
Is Juice Defender a task killer? Not really sure what is it but I've been wondering about that.
Juice Defender Ultimate has been giving me about a 1/3 more time with screen on max. Why is my screen on max, because I was trying to drain the phone. It's on about 40% now which is still pretty bright. I wouldn't be mad to get more life but I think 20+ hrs with moderate use isn't bad. I think the most I did was search the net about 4 hours total. But I was also, customizing, so it the screen was lit for a while.
This is a TMO GSII I'm talking about.
There are a ton of things you can do, but the truth of it all is that our 3G/4G radios pull so hard they drain the battery, which is why you were on the right track when you disable active since, Facebook and Twitter.
The main two things I do, is
1. add a widget for turning off 3G or 4G (If its in your area).
2. Installed Startup Manager ( it disables startup programs in the unseen background, (my phone is rooted)).
by doing these two things I am able to get 17hrs+ on a standard HTC EVO 4G battery. Keep in mind the more you use the Internet the more it will drain your battery. So I only turn the internet connection on when I need it or the app needs it.
*I also only use one screen and remove unnecessary widgets but I find that doesn't help the battery life all that much, (my personal Preference)
*When I or my sons game on my phone I put it on Airplane more which turns off all Radios including the Phone (call/text)
*Drawback to turning 3G off, you have to wait a few second for the internet to come back on and MMS won't download through your messenger unless have it one.
I've been off the charge for 8hrs and my battery life is still at 65%
Sorry to be long winded but if I know anything its battery life
Completely agree. What's the point. Either you don't use your phone for ANYTHING, and watch the battery last for 2 weeks (literally), or you use it so heavily that it lasts only 2 hours....
I was sick recently, and as such couldn't use my phone (I couldn't open my eyes without getting dizzy, and even closed.... still was). Suddenly my HTC Inspire 4G used only 20% of the battery in 10 hours. The previous day, heavy mail, "friendstream" (HTC's facebook/twitter/etc app/widget), listening to music (well, audiobooks) for about 8 hours, and I had only 20% left. And i've found that overclocking the phone to 1.3GHz helps more than any other tweak.
Don't get me wrong, I'm obsessive about using my phone *and* getting awesome battery life out of it. But the ONLY way to true "maximize" your battery life is to *minimize* your usage. But then you might as well buy a feature phone.
And I know a few people with iPhones. a 3GS and a 4 and a 4S. They don't get any better battery life than I do. Heck, they get worse. Even under the same type of usage.
For me, the problem isn't the usage, isn't what's running, or what's loaded (but it does help/hurt). The problem is that battery technology has NOT kept up with consumer needs, or IT development. Your battery is dying as soon as it leaves the factory. Your battery is dying every time you change it. Especially when it gets hot. your battery dies faster when it's cold outside. We need better energy storage medium. Period.
Buy the biggest battery I can find on eBay....
Use the fsck out of my phone all day and have plenty of battery left.
Problem solved.

<<<< What he said
I don't think the use of WiFi could be overstated.
On my Skyrocket, leaving Wifi on (indoors), it'll sip about 1% every hour. I go out and have 4G LTE on, it drinks up about 3% every hour.
Minimizing widgets also helps. I saw noticeably better battery after removing my facebook and Latitude widgets.
The screen also sucks up the most battery. Turn it off on every occasion. Just turning it off instead of letting it shut off by itself has made a difference for me.

Battery technology has kept up with usage. However, battery size in relation to the power draw, has not.
Compare the size of the back cover on your phone, with the size of the battery. Why is the battery this tiny little 2" square, when the phone is 5" tall and 2.5" wide? Why aren't batteries the same height/width as the phone? Why isn't the battery the same size as the back cover? Why aren't phone manufacturers optimising the size of the battery (meaning, making it as big as possible)?
It would be so nice if phone manufacturers would stop with this stupid "race to the thinnest" crap, and started:
- releasing phones that are actually comfortable to hold like a phone
- releasing phones with batteries larger than a pack of matches
your battery dies faster when it's cold outside.

Actually, keeping a battery cool makes it last longer, not drain faster.
Can someone please help me with my horrible battery life on my infuse? I cant make it a whole day on my phone. I don't play games on it at all during the day because I work. The only thing I do is make calls and text. I had 100% battery this morning at 6:00am and it is now 1:30pm and I am down to 12%. I am running the latest version of catyrom on my phone and it was supposed to increase the battery life. My phone is less than a year old (probably only 6 months old if that) so the battery on it should not be shot. Any help would be awesome!
THANKS!

Should not be like that. All the uckl2 base ROM have very good battery life.
Try a reflash. I would go into cwm, wipe data, wrote cache, wipe dalvik, fix permission, go to mount, wipe system, data and cache. Re flash ...i would try Another uckl2 base ROM then go back to caty if battery seems better
Buy Juicedefender Ultimate, set it up whichever way works for you. I couldn't tell you about Catyrom and the JD AOSP helper compatibility.
Buy and set up SetCPU to downclock your CPU when your screen is off, and when your phone's charge goes under a certain amount. Change your governor to conservative, ondemand, or smartass. Those will help. You could try undervolting, but be wary of doing it too much.
Look at your battery useage history and work out your app issues from there.
A faster microSD card wouldn't hurt, class 4, 6, or 10 would be better than a class 2, if you're even using a microSD card. Faster read/write means less time reading/writing.
If you need even more power, you could always go to 2G networks if Catyrom allows you to use them. From my experience, it will interfere with speakers on other devices. I have ~8 pairs of speakers in my office, and the interference drives all my co-workers nuts.
And you could always carry a spare battery, which isn't the best of options, but it's a sure fire way to go on
Reduce the number of widgets you use, reduce the number of screens you have, remove redundancy in your apps, and turn off live wallpapers.
Turn off auto brightness, and set it down to lowest valuable that is useable, then bump it up just a bit more. Then set your timeout to something conservative such as 15 or 30seconds or 1 minute.

Thanks! I downloaded juicedefender and setcpu both. I had seen juicedefender in the market but was a little questionable about what it does. but I will see what and how good it does tomorrow. I have my phone charging right now so I will upload a pic of my battery life tomorrow around 3 so we can see how my phone is doing. When I looked at the battery usage when I plugged in my phone it was on for 7h 34m 24s on battery and when I plugged it in I had 6% battery. I really hope that this works. like I said all I do is text and call during the day.
Thanks again!

JuiceDefender, to put it shortly, will kill your data connection/wifi/gps automatically and will enable them again on a schedule.
Those won't interfere with your texting or calling, but it will interfere slightly with your MMS. You'll have to wait for data to be re-enabled to download pictures/videos.
You can set up a schedule for work to be on a more frequent basis than the one when you're not at work, and once you set the battery threshold and the "ignore on low battery" function, it will stop all schedules once the battery reaches that point.
It will re-enable data/wifi when you turn your screen on so you can use it.
That's about most of what it does and it does work very well.
If you'd like, you can get cheap spare batteries from ebay. They mostly ship from China so they take up to a month to get to you, but they're very inexpensive. I just got my 2200 mAh battery (it fits just like the stock one) and it's not even broken in yet. It's 2 PM where I am and I unplugged my phone at ~8. I'm still above 65%. I don't tend to have very restricted battery use like some folks, but I do look for ways to reduce the battery waste. Most of my stuff works when the phone is in idle/deep sleep. I haven't done much of anything today with the exception of a very few calls and a few texts, a little surfing, and I downloaded a CM7 update from the CM7 port's thread.
When it's been broken in it should do better. CM7 isn't as battery friendly as some other ROMs but I like it very much so far. I have been furiously debating whether or not to move to Zeus ROM, as it seems like the big boy's Infuse ROM right now but I can't tuck away CM7 just yet
EDIT: Another, probably very minor, battery saver would be to download and install Adfree. It reroutes all outbound requests for advertisements to the device itself, so those don't download data and you don't see ads. Instead of them possibly keeping your scheduled data connection on for longer while they download (or pumping up your data useage), they never go outbound because they don't require internet access once checked against the HOSTS file.
Also don't forget to do what qkster advised. Bad flashes do happen, and you could have just had a bad flash.
Bassman--What does about phone say is eating the battery?
Sent from my SAMSUNG-SGH-I997 using XDA App
I have never gotten what I thought was decent battery life out of this phone... I work as a field tech so this phone is my office... Serendipity gave me the best battery life of any rom I've tried and I've tried several.
When I first got it I used Infused rom I would average 3 to 4 batteries a day. When I went GB roms that dropped drastically to 1-2... Serendipity would get me through the work day (8-10hrs) and home w/ a little to spare. Lately I have been bouncing back and forth between caty and zeus averaging 2+ batteries a day.
Might add I received my phone as a hand me down from someone at work. He only used it for a few weeks but kept it stock.
On any rooted ROM, i usually use tibu and delete buddy now, facebook, att, tether manager, devive update manager, etc..every possible background crap.
Every user is different, but with just calls and text, is not unusual for me to have 2-3 days before a charge.
Data sync and wifi off when not using data
Rxnelson the about phone says display. But that is the case on almost all phones. I have my auto off set to 1min

You can also try following basic methods:-
1. Turn Off: GPS, WiFi, Screen Rotation, Bluetooth, APN, Vibration, Animation etc.
2. Minimum Screen Brightness Settings
3. Minimum Screen Timeout setting.
4. Dont install Widgets based apps on home-screen
5. Kill the un-necessary background apps from Task Manager.
6. Use black theme in apps.
Thanks

Something I've found helps a lot is rebooting every morning. I'm running Zeus and noticed that the first day after a reboot I get great battery life (light- to medium-use would leave the battery at 50% after 12 hours). By the second or third day, I'd barely make it through the day. Since I've started rebooting every morning my battery life has been great. I also used BetterBatteryStats to help figure out which apps were keeping my phone awake. I learned that the Stocks app runs in the background waking the phone regardless of settings. Juice Defender is really a waste of time - you'll get better battery life by figuring out what's killing your battery and getting rid of it than having Juice Defender disable all of your phone's features when the screen is off(while using battery itself).
Man your battery life shouldn't be that bad. If it isn't a bad ROM flash then you could have a bad battery. Sometimes batteries die after a few months.
I did a lot of testing for apps and whatnot to try and see if I could maximize battery life. I tried all the juice defender and similar apps and didn't really like how they were killing off my services when the screen was off.
I found out that the main killers of my battery life were specific apps. When I used email apps with IMAP push services I noticed that they would kill my battery because they kept preventing my device from sleeping. I sometimes need about 18 hours in a day before I can charge so I really wanted to maxmize the battery as much as I could. I monitor new apps when I install them. Some seem sneaky so the battery stats might say that the app is only using something like 4% but it is also making the Android OS keep alive and use a higher percentage. I have about 70 apps installed but deleted most of the apps that seemed to kill my battery. In an 18 hour day now it is common for me to have at least 50% or more battery left over. It did take me a while to get this kind of battery life though. I was getting pretty frustrated for a while.
I'm running stock GB 2.3.3 (Rogers) and I am on the Bell network in the Great White North.
Hi all, just got my 11yr old son a ChaCha. He wanted a Blackberry for the keyboard, but managed to persuade him to have the ChaCha. Anyway, it seems to have this infamous dialer bug.From reading throu the forums, am I right in thinking that if I put a custom rom on, it will get rid of the dialer bug? He curently takes it to school, at 100% power, and generally comes home with the phone on around 10-20% power!! He is only allowed to use it at break and lunchtime!! Also, as it's for my kid, I would like it to be as close to stock as possible. Any recommendations? As I already own a customised Desire, I am happy to 'play about'. I have already unlocked the bootloader, and rooted, so that I can use link2sd. Without that he could only install 3 apps on it before it got the low disk space warning!! And as he's only 11, he likes to put a lot of junk on his phone!! Any help would be most appreacited. Thanks.
Like I mentioned here, I don't think that the dialer bug really exists. It's just the battery statistics that are not very clear.
The overall battery performance of the Chacha is very bad, so if you play some games they could drown the battery within an hour. There only thing you could do is rooting the phone and using another ROM. You can win a little with this, but for playing games, Chacha has a very bad battery performance.
Best performance was with CM7 - there my battery live was 1 1/2 days (without playing games), with CM9 now it's less then a day again.
So for better battery performance and keyboard I guess the Motorola Pro is the only phone, or non-Android phones.
I agree. There is no dialer bug. Those are many processes that show as Dialer. I don't mean to offend you, but have you considered that your son is using the phone not just at break and lunchtime? It is hard to resist, especially when it comes to new things. You should test it yourself and see if battery drains that much in that specific time frame.
Regards
Custom ROM would be a good option, but as he's 11, he's probably not old enough to appreciate the faster speed of CM7 or CM9, over his front camera. I'm guessing he'd want his front camera to keep on working lol
But when I was using the stock rom, I just turned my 3G data off whenever I was not using it, and that makes the battery last miles longer
For easyness (lazyness). Create a widget on the homescreen, under Settings and Mobile Internet. And then you'll have a widget you can just tap to turn on and off the mobile data as long as your son can get the hang off turning it off when he's not using it, then that should work a treat
go for CM Roms
IMHO I do believe that there's a dialer bug in stock Chacha, I think it is caused by the dialer's continuous polling of the proximity sensor (this bug has been reported in a lot of htc stock gingerbread phones, the app dx battery helped me confirm this.) Custom ROMs helped me solved this bug but only those that are CM-based (stock-based roms still has the dialer bug). CM7 is very stable and has the best battery life for any Chacha ROM but CM9 just looks so damn good and the battery life is still way better than stock (in stock, I get battery drains even if my phone is just idle, wifi off)
Thanks for the advice guys. I think we will leave it a couple of weeks and see how it goes. May end up putting CM7 on it at some stage, as I have a CM7 based ROM on my desire. He is only allowed to use it between lessons, otherwise it's detention!! He also uses it to listen to music to and from school. And yes, I have notice that the battery goes down rather quickly, when I was setting it up for him.
Well, there sure is a bug in the stock rom that drains it within hours. IMO it's coming from the 3G connection... Sometimes, when my coworkers drive me crazy, I turn off the 3G... I live in a neighbourhood with a bad network connection, this means that it is reconnecting all the time. My battery normally went for about 15 hours, with 3G off it works for over 20 hours. But since I've installed CM9 it stays alive for over 40 hours...
