Battery life sucks

I've had my battery replaced, I've wiped my phone from ROMs, and I've used aggressive SetCPU profiles...
What is annoying though is setCPU recently updated and I decided to see how my phone ran without it.. battery life is horrific with a simple UV kernel.. Why is this?
I mean I take my phone off the charger at 11am and by 10pm its less than 15% remaining. I now have a second battery from HTC after a warranty replacement but I saw very little change. I have a task manager that auto kills everything now which helps but it is annoying since I lost my car charger my phone is discharging all day.
Is this normal and I'm just freaking out or do I have a real problem?
Running Kang-o-rama ROM with ~20 apps

I know 3 things about the N1 battery:
1) it took a couple of weeks for my battery life to max. Lithium batteries need a break-in period. They have no memory, and the recommended approach of not using the phone until it's full charged is bunk. Just use it normally and it will work as it should.
2) Switching between 2G and 3G constantly murders the battery, 4 hours and you're dead. If you're going to be in an area like that for a while, force it to one or the other.
3) Watch your apps. If your phone is acting even slightly sluggish it's CPU is maxed which is killing your battery. Slowly swipe between homescreen pages, it should be silky smooth without any stutter. Try and track down which one it is and either install/reinstall (which fixed an issue with Better Keyboard for me) or completely uninstall if you can't fix it. Check for apps that ping the network too often, or ones that start up on their own.
I will add that the built-in 2.1 battery usage tracker is not 100% accurate. In my Better Keyboard example, Android said it was the screen using all the juice, not the app. Might have to do with video graphics drivers, I really don't know. Point is, after uninstall/reinstall my screen used 55% of my battery instead of 75%, so don't trust it.

Are you kidding? You're running your N1 for nearly 12hours and you STILL have 15% juice left?!?
Search the forums, 12hrs and still having juice left would be considered excellent to many.
...Then again, you haven't mentioned what your usage is like. If we were talking about your phone being in sleep mode for most of those 12hrs with just an occasional call or 2 that only lasted very briefly...Then that's a different story.

Have a look at Juicedefender, it will limit your internet access to 1Min on every 15Mins when the phone is asleep/screen is off. Does wonders for battery life

[Q] Tips to extend battery life? Anyone?

Hey guys,
Just got my Epic yesterday.. coming from the G1 with lots of experience loading and tweaking ROMs and dealing with same/similar battery issues.
After unpacking the Epic I used it and let it drain down to zero before recharging it; after a full recharge, I loaded up the 7 screens with widgets and ran a live wallpaper (fish). I didn't really use the phone much at all and the phone went from 100% battery down to zero in the span of only four hours!!! Geeze, you've got to be kidding me - four hours battery life?? WTF????!!
Back to the drawing board: I rooted it and ran SetCPU with some power saving profiles. Removed the live wallpaper and went to stock wallpaper. Set display power off at 30 seconds. Note that 4G remains off since there's no 4G in my area..
Couple of questions:
1. Is there any way to toggle 2G/3G like there was on my old G1? I know that was a power saver.
2. I didn't stop to read all the documentation yet (typical male, I know) but is there any way to wake this thing up from sleep mode besides pressing the power button? I can see that power button breaking for as much use as it's getting from me constantly having to wake this thing up!
3. My brightness setting is set to auto - since the display is usually the biggest drain on these things, is there a recommended manual brightness setting (percentage) that seems to work well for you and saves on battery power?
I'm waiting for the Seideo Extended Battery (just like many of you) and am wondering if I should keep the Epic since I'm on the Sprint 30-day Easy Return program.
Appreciate hearing from everyone!
Chris R.

I don't have 4G where I am. But, I have a all black wallpaper(uses less power) and unrooted. I easily get about 12-18hr out of my phone wit normal use(text, talk, and surfing the net with skyfire). Only thing that really kills my battery are games(Robo Defense can take over 30min to play one game).

Thanks for the reply - situation NOT improving
Thanks for the reply.. unfortunately, the situation is not improving...
I tried setting a Sleep Profile using SetCPU that would under-clock the CPU (using the stock kernel) once the screen dimmed and the phone went into Sleep Mode. Unfortunately, as mentioned in another thread here, the result was that the phone froze and required a battery-pull to reset.
I'm really starting to lose my enthusiasm for this device; as beautiful a display and as responsive a CPU/GPU, all of that doesn't mean much if you don't have good power management built into the firmware. At 6PM this evening I pulled it off the charger at 67% charged, it's now 8:35 PM, only 2.5 hours later and I'm down to 22%. I'm in a decent coverage area and get 2-4 bars of 3G strength so I don't think it's an issue of the radio being the culprit; in-fact if you check the battery stats it reports that that lovely Display is accountable for 78% of the battery usage! So I guess we're paying a hefty price for these 4-inch AMOLED displays!
I read somewhere else that the most recent update (DI07) has caused the battery performance to decrease; since my unit is brand-new it immediately went and installed DI07 shortly after the first boot-up so I have nothing to compare it to.. can anyone comment on that?
Thanks!
Chris R.

I'm sure custom ROMs will put performance / battery life on the top of the list but until then, I use JuiceDefender beta and have seen pretty good results with it. It shuts off data whenever the screen is off and since my screen is off a good amount (only use my phone if I need to check email, call, and / or text, which is rare when I'm at work). Other than that, yes, use black wallpaper, lower brightness to the min. in the OS and browser, and don't leave apps that constantly use 3G open (things like ebuddy, pandora, etc.). 3G really destroys battery life so minimal use of 3G data would maximize battery life. Maybe the devs can figure out a way to get at least one full day of battery life on this phone. I'm hoping that is the case.
As to your post, yes, DI07 has resulted in poorer battery life, for whatever reason. I was definitely getting a few hours more with the older firmware. I would not lose hope yet. As disappointed as you are (and all of us are, I can assure you of that), the devs are really starting to push out nice ROMs already, and in a few weeks to a month, I bet we will see some solid battery life. Hell, even 2.2 should yield much better results. Patience

Thanks for the tip!

DI07 has hurt my battery life substantially. In fact, my battery drains very close to twice as fast now with the update. I don't understand what they did. My phone certainly doesn't seem any faster, my display is dimmer, and battery life sucks. I'm going to have to go back to DG27 so I can use my phone all day. With DI07 it always dies on me by mid afternoon. With DG27 it was still running by 11pm at night without even a battery low warning.

juice defender ftw
also, use advanced task killer with low security settings to kill all the background processes. Set the autokill to when the screen turns off. This keeps everything pretty well managed and helps with battery as well

JUICE DEFENDER BATTERY!!! Saved my phone from flying out of my car window at 10 in the morning........

here is a link to a thread I started.
Sharing my juice defender settings. I also use ultimate juice.
http://forum.ppcgeeks.com/sprint-epic-4g/133933-sharing-my-juice-defender-settings.html
I can get a day and a half (or slightly longer) out of a single charge.
YMMV.
Hope this helps

Advanced task killer + Juice Defender. You could also get some custom roms and Kernals that would help boost it.
But that's your best hope. Keep off 4g, wifi, bluetooth, etc.

Ah, the evils of DRM can strike in unexpected ways...
I wasn't really having a battery problem but I just turned DRM off, so we'll see if battery life improves anyway.
I had a whole long post here that got wiped with the xda disk array failure, so I'll just sum that up here too:
1) Use wi-fi if possible - it REALLY helps
2) 4G does not seem to use the battery any more than 3G, although hunting for 4G does and 4G coverage is not as extensive as 3G even in 4G areas. So it's still best to leave it off if you're moving around.
3) Dim your screen and use a dark, static background. AMOLED screens don't work like LCD's; they use more power the more pixels are lit and the brighter they are.
4) GPS also kills your battery - leave that off unless you need it too.
I think that's it. I get about 18 hours on DI07 (even before trying the DRM thing; maybe I can get to a full day!).
One thing I'm noticing after checking DRM - I've got Google Maps' LocationService popping up about every 10 seconds, and I can't seem to shut it off permanently. (I went into Lattitude and turned that off, not sure what else to do.) That can't be helping... anyone know how to get rid of that?

I'm using juice defender and a constant email junkie, but lite use on other aspects of the phone. It goes off charger at 5:30 am and I'm about 67% at around 3p. It then goes in the car charger on the way home. This has much better battery life than the Pre or the Hero as with both I had to turn off email to get it to last throughout the day.
I don't expect these phones to last days, but I expect any phone that I get to last the business day. I've always been one to charge overnight.

Wifi drains battery more from what I've read.

I've heard the opposite that wifi (as long as it's connected) uses up less battery than 3g/4g. Any of them will suck the battery dry if they're searching, so make sure you have a connection to one of them.

Hi everyone, new to the forum. Just started checking it out when the Epic was released and this is my first post. Anyways, here's my question. My phone's been off the charger for 7 hours and 17 minutes and it is now down to 15%.
Display 79%
Cell standby 7%
Android System 4%
Phone idle 2%
Swype 2%
I've gone into the display settings and I thought I had set everything up optimally. The brightness is always very low. The screen timeout is 15 seconds and the keyboard matches that. I don't know what else I can do to cripple the phone to get the battery to last longer.
I have had wifi on, 4g off, bluetooth off, gps off. Really all I have done this afternoon while watching NFL games is check my yahoo fantasy score, play 2 games of WordFeud, and check twitter and facebook. I purchased Juice Defender a week ago and it has been running all day.
Any suggestions for how I can reduce the drain from the display? My background is a black and white picture of a friend of mine, which I thought would help.
Don't get me wrong, I love this phone. But the battery life I've seen is just terrible. I'd love to buy the extended battery from Seidio whenever its available, at least that would make it last longer even if the settings aren't tweaked.

Do you have juice defender installed?

Yep. Its installed and running now.

There are only two reasons for your display to be using that much battery:
a) it's too bright, or
b) you're using it a lot.
If you're using the phone a lot, your battery's going to run out pretty quick and there's no way around that. If you're using it a "normal" amount, which to me means maybe an hour *total* per day of having the display on, then the other culprit is going to be your brightness. (Some would argue that's less than a normal amount, but think about it... you get a new phone, you're going to play with it for a week or two until you've seen all the cool stuff. But at some point you're going to start putting it away most of the time and just using it when someone calls you, you get a message/email or maybe to play a game or two while waiting for the train.)
Set your brightness *all* the way down, just as a test for a couple days. Make sure all the "power saving" features of the display are turned *off* (auto brightness, and whatever that "picture detection" feature's called, I can't remember). You just want the display as dim as possible all the time, just to see what happens. See what the battery usage says after a day or two of this.
My bet is that you'll see a drop, and then as you get into a more normal usage pattern it'll drop further still. You can raise the brightness a couple ticks then as you learn how to stretch your battery out.
Personally, my display is rarely over 15% or so of my usage. Today it's 29%, but it's a Sunday and I don't have anything better to do but play around on my phone.
btw, it's still the first day I've tried this but that DRM thing might be working. It's almost 9PM and I'm still on like 80% battery, and like I said I have been using the phone off and on throughout the day.

That has helped tremendously. I installed it pretty much when I got the phone and I'm able to last the whole work day with 67% left. (10 hour day)

[Q] Battery Life so far?? Report!!

Hey new myTouch 4G owners. I know your loving your phone so far but I and many others want to know one thing. How is your battery life so far? Compared to your previous phone?? and have it manage a day through your heavy usage yet?
Thanks!
P.S: if you can, report your "display" on time or just take a picture of "battery use" ..

I use the "Battery Left Widget". It's about 80% calibrated right now, reporting that my full battery life (based on my usage) is roughly 15 1/2 hours.
Having used the same widget on the Nexus One, I'd say it's pretty much right in line with what I was getting there.

Hmm I guess no great battery life then?

I must say though that my phone probably isn't the best representative for battery life... Reception here at work is weak, causing the phone to boost it's power output.
When I am at home, I get much better battery life.

I picked my phone up on the morning of launch and I'm still on my first charge (15% left). I've used it for calls, texts, pictures, videos, apps & widgets and I installed the ota update. I've had great battery life so far.

Mine only came about 60% charged.
So far my battery has been the best of any android phone so far (Nexus -> G2 -> MyTouch 4G). I have about 10 sync accounts going (2 gmail, facebook, rss feeds, etc) and with moderate use I have 40% or so at the end of a day. Screen is on auto, quite usable in any light.

Wow..not bad..so what are your display on time saying? It's in the battery use section, click on display.

guess not then

my battery is ****. I had to charge it half way through the day, but I'm an android noobie and lookin to get this thing going easily a whole day hopefully.

my battery life is ok. doesnt last the whole day for me but i text a lot make some phone calls and download apps and play games like assassins creed and nova.

The battery will need a few charging cycles to reach its full potential. I'd recommend fully discharging and fully charging it the first few times (and every so often after a few weeks of use). You probably won't get the most representative results on day 2 after launch. Was the same for my Nexus and G2

Oh ok i will have to try that out. I usually charge my phone when it gets down to 20 percent. But i left it fully charge over night

Mine seems about 4 hours shy of my G2.
My weekdays are 20hrs on G2 and about 16 on mT
Weekends are about 12 hrs on G2 and about 8 on mT

Amazing in terms of any other android phone I've owned.. Without a task killer
Sent from my HTC Glacier using XDA App

For some reason when it's rooted it lasts longer. If I don't root it the battery goes fast.
myTouch4G (Glacier)

i fully discharged when i got the phone and charged it over night. I went to an air show today and unplugged it around 9. its now 10 and i still have 25% left
(i uploaded pics to my blog and facebook, made calls, got text, checked football scores, and used google maps)
i'm impressed. Way better then when i had my EVO

everyone is giving answers as either "my battery life is great" or "my battery life sucks" but that doesnt really say anything... your battery life is gonna be amazing if you dim the screen to zero and dont use data :/ its all gonna be on how you use the phone and everyones gonna use the phone differently...
bottom line... the answer to this question just has to many variables

I am happy with battery life so far... while not analytical, I am getting as good or better tham MTG3. I was able to play Monopoly for an hour and the better was still 3/4.

I bought the MT this past Wed and when I bought it, the level was at about 40-50%. I was messing around with it, adjusting it and it lasted for a good 3-4 hours with the factory charge.
I let it die then fully charge and removed it from the charger. That charge held from 5am all the way until 1am the that late evening with regular use. It died and again I did a charge and disconnect.
I have done this same cycle for the last 3 days and right now. I can consistently keep a high charge for the most part of the day with average use. I disconnected the charger this morning at about 1 am, and here I sit now at 945pm with still over 75% charge.
Seems like this phone really likes the power cycles right now. Full to dead, recharge then remove until dead...etc.
Since Wed afternoon, I have charged my phone only 3 times since purchase, and right now it is Sat night. This is with average use, brightness set about 25%, auto sync only for email, weather, tmobile and no task killer used

You must remember this phone is using a powerful 1Ghz snapdragon, with a small battery. By default android uses the governor called ondemand, in other words it automatically shoots up to max freq during use. But once the 4G is rooted, you can use SetCpu to make changes, tmo will probably make an update though to address the issue. I can't really see extended batteries being made to small without needing a new back. I'm considering the 4G, I currently use both phones in my sig, my slide can get 2 days max, my G1 around 10hrs. It all depends on how you use the phone.
tips:
-turn down brightness
-turn off gps/Bt/wifi
-switch to 2g/3g/H depending on signal
-dial *#*#4636#*#* to modify radio settings(2g/3g/etc)
-turn off background updates(twitt/fb/flickr/etc)

[Q] horrible battery life! anyone else?

Hi, I been having the HTC Surround for a little over a week now. I love the look and feel to it (I know OS wise it has a lot of improvements to do but I'm willing to put up with it for a bit, considering its a new OS). However one thing I notice is that it has horrible battery life! The phone last about 10/12 Hrs on a full charge. During this time period, there is no heavy use; tops 50 txt messages send and received, about an hour of music, screen lock (brightness set to low, when on), perhaps 15 minutes of talk time, data connection turn off, about 20 minutes of WiFi (I turn off WiFi when not in use), rest of the time on stand by as mention before (with the screen locked). Another thing i noticed yesterday night was that my phone was charge completely, i left it on stand by and within 5 hrs that i slept the phone had gone a little lower than 3/4ths (data connection was off).
I read a post here that said battery may drain quicker when phone is left in cold weather and i thought maybe this could be the case. However I'm really skeptical because i live in Los Angeles. Cold weather, which is this time of the year, is mid 40 degrees at its lowest! That's not cold! But anyways i guess I'll try putting that theory on a test (imma try keeping it warm, see if it makes a difference)
so is anyone else experiencing horrible battery life? Or am I just an unlucky person who got a defective battery?
THANKS in advance

What "theme" are you using?

If I don't use my phone, it will last for days. Even when I use it through out the day, it lasts well into the next morning/afternoon.
The battery life does get better the more you drain/charge it.

well, I been having it for a week now. I seen no difference in battery life. But imma give it another week or so. See if this works. Then I'm gonna try buying different battery. If that doesn't help, I think I'm going to have to switch back to my Samsung Captivate. I would hate doing this, but this type of battery life is a deal breaker. Today, it was even worse! It lasted me only 9hrs while I was at work, which at least 8 of those hrs it was on stand by!

Sounds like you have a bad battery, bro. I'd get it replaced at the store you bought it from.

yeah, I'm going to try this on my day off which is on Monday. Also gives me time to test out the other persons suggestion
thanks for your opinions. I'll get back to you guys and see what happens.

My surround - now two weeks old is showing much improved battery life. It didn't make it through a day when I first got it. Part of that was due to my fiddling with it and part due - I think - to the battery conditioning.
Now, it is going a full day on a charge. I am also switching off 3G and on WiFi when I am in my office or home. It is a bit of a pain in the butt and I hope that M$ gives up some APIs soon so that someone - cough Bruce Jackson cough - will write an app. We'll see.

I have noticed that the Bluetooth drains the battery considerably faster. Try turning Bluetooth off when you don't need it.

I don't use the Bluetooth at all. So this can't be the problem. but thanks anyways. (I might need this information since I was planing on using one in the near future).
So I notice that now, my Surround does get better battery life. (which is absolutely crazy! since now I have the screen brightness on medium and data turn on lol). I guess the battery just needed to be use and charge a bit more. However, I still think battery life could be improved. (hopefully, future updates will teak some system settings that will do this)
I have also decided that I will keep my Surround instead of going back to my Captivate I wish battery life would be better and the OS to be more "open" but truth be told, I fell in love with my phone haha Then when i went back to my Samsung Captivate, it felt weird. Android felt much slower.
So i gave it a little test; I launched messaging, email, music, browser, etc on both phones at the same time. Turns out both of them launch these native applications in the same amount of time.
I guess what makes WP7 fell smother and faster is the (eyecandy) transitions.

think its the battery
ya i have had mine for 2 weeks now and i think the problem is the fact that the battery is a 1230mAh, and we also have a samsung focus with a 1450mAh battery that will last an exra 2-3 hours longer which makes a huge difference! im hoping htc will make a larger mAh battery avaliable, mine will only last anywhere from 5-7 hours from normal use

I just ordered a Mugen 1300mah battery..not *much* more capacity, but hopefully it helps a bit!

if i dont use my surround (like not using too much 3g, wifi, music, gaming, and just normal phone calls and texts) it can last a whole day and probably a lil more, but when i do too much 3g/wifi/gaming/music it drains quickkkkkk.
and i do hope htc will have a larger capacity battery for the surround soon... 1230 is kinda small compare to other phones nowadays..
but still this has much better battery life than my previous phones (diamond2 and touchpro)
i just find myself carrying the usb cable and wall charger alot in my bag :]
and having a car charger is a plus also.

My girlfreind has had the phone since xmas. Initially the battery would lose its charge very quickly. I had her do a bump charge and just let the battery settle in. She can now go up a third day wothout the need for a charge with moderate txt.
Be aware the quick drop whenn taking it off the charger is NORMAL. Read this thread for a discussion of that http://forum.xda-developers.com/showthread.php?t=871051

Agree - Bad Battery Life - But not as bad as some....
Smart phones, in general, aren't what I would call great at conserving battery life under any condition. Pick any model of high-end smart phone and tell me who can get more than 2 days (using every trick in the book to eliminate unnecessary drain). Yes, this phone is under-powered in terms of only having a 1300 mAh battery when it should have a 1400 or 1500.
Cut the unnecessary stuff when you are not using it - Bluetooth, WiFi, etc.
You can easily get a day + out of this phone with moderate/mixed use (some talking, some browsing, some multi-media viewing). That's pretty good, I'd say (from my relative experience across many different types of smart phones). I just plug it in every night.....pick it up in the morning and go. Haven't had any issues with it running out during the day.
Now, if you are starting first thing in the morning and running movies, have the bluetooth going, the WiFi on........well, heck yes, you are going to have a battery drain problem. If you want to run it that way.....just leave it plugged in.

Has anyone used a Seidio Innocell 1300mAh Replacement battery? Was wondering if it was worth the investment to improve the Surround's poor battery performance.
Thanks,

So...when is someone gonna step up to the plate and improve battery technology? It really sucks that these phone manufacturers are giving us ALL these fancy features that drain the battery and when we complain about having poor battery life they are telling us to not use all those fancy features...kinda defeats the purpose of buying a smartphone, am I right?

guys .. wake PLZ UP ))
1 ghz (1-2 core cpu ) ..
3.8 and more screen ..
DEDICATED GRAPHICS .
OS .
with DIRECTX9 Interface .
and that all spiced up with 1600 ma battery in best case .
and that you wana to run more then 6 hours on full load ? say THX TO MS .. for NON multitask os .. overwise battery life was even more lol then this

My surround - now two weeks old is showing much improved battery life. It didn't make it through a day when I first got it. Part of that was due to my fiddling with it and part due - I think - to the battery conditioning.
Now, it is going a full day on a charge. I am also switching off 3G and on WiFi when I am in my office or home. It is a bit of a pain in the butt and I hope that M$ gives up some APIs soon so that someone - cough Bruce Jackson cough - will write an app. We'll see.

I noticed this as well. As time went by the battery actually started to last longer. When i first got it i used it less than i do now and the battery would die before i even got home for work. Now it lasts till about an hour or so after i finish and get home.

does the surround use the same battery as the HTC desire HD?
Theres an ebay seller that is selling a surround battery and wall charger but the wall charger has a sticker that says: For HTC Desire HD

Insane Battery Life

I'm hitting 41 hours and still have 19% battery life. I noticed it took around 10 full charges before my phone started to get this great battery life. I've been using it as normal and even listened to howard stern for a couple of hours yesterday. Talked on the phone a bunch of times around 30 texts and even used my 4g for a few minutes. I've never had an andorid phone last this long for me even when I had my Optimus S which I thought was awesome.
Anyone else getting this awesome battery life? I'll post screen shots when its about dead as I dont want to plug the phone into usb to get the pics.

Charging twice a day here. Its worse than my hero.

I would investigate as that shouldnt be. My shift lasts almost 2.5x my hero. I bet if I had your phone in front of my I could find out whats killing it soo fast.
Is your phone getting hot? I would do a full system wipe and start over from scratch and see if it doesnt get better after you try the things I've listed below. Note, I didnt have this great of battery life until 6 days after I purchased the phone and charged and discharged numerous times. The first few days the battery life was not good at all.
A little list of things to do, check and or disable;
1. Use spare parts and find out whats killing your battery ie partial wake usage, cpu etc.
2. Turn your window animations from all to only some animations
3. Turn off automatic display and keep it around 20-30%
4. I have auto sync off on all my appz (E-mail, Gmail, Facebook etc.). I update my E-mail and such manually.
5. Turn off data when not using it. I find data accounts for around 15-25% of juice used and thats just when on idle.
6. Only use widgets on the homescreen if you really have to (Running widgets use a lot of power over time)
7. Use Android Hackers tool from the market and it will break down how long your cpu was in a certain state. ie my cpu spent 65% at 245mhz and 28% at 806mhz.
8. Keep off 4G, Bluetooth, wirless networks for location and GPS if not using it (GPS uses less power than wireless networks and is more accurate anyway) I assigned Quick Settings to open when I hold down the search button. That makes it easy to enable/disable any of these setting within seconds.
9. Turn off google talk and make sure it doesnt sign in automatically (most people dont realise this)
10. Turn screen timeout to 15 or 30 seconds (if longer your phone can keep the display on accidentally while in your pocket if a button is pressed, wasting power)
11. Dont use a task killer unless its to kill an app you know drains your battery and therefore must be closed to save juice
12. Check your apps. Some apps keep using cpu etc because they were not programed correctly. (some appz I've found to drain my battery are; Yahoo Mail, Craigslist, AndTorrent and the market if a download is hung up. There are a few others I cant remember off the top of my head) If your phone is getting hot for no apparent reason this may be the cause.
13. Calibrate your battery by bump charging (charge your phone till its full while on, turn it off and charge till its full again. Then bump charge it around 5-7 times) Wipe battery stats if applicable. If you have a car charger, plug your phone in on the way to work to account for the little bit of drain that occurs once the phone is fully charged yet still on the charger.
Remember you can get china made batteries for very cheap. I paid $12 for 2 batteries and a wall charger off ebay. This phone uses the same batteries as the Hero and Evo by the way.

I noticed Yahoo mail and Craigs list apps I downloaded from the market have a memory/cpu leak that kills your phone super fast.

yahoo mail DESTROYED my battery life on my hero so i havent used it in forever...sad to see it still had that problem....also I stopped using any battery widgets that show the exact percentage (as these are usually wrong anyway) and went back to using stock browser (Miren browser, while I really liked it, was eating my...)....i now check my battery through the settings....I was having varying battery life but after recalibrating by letting it die all the way then charging it up full i most recently got like 30 hours off the charger with moderate use and got down to 10%....coulda probably squeezed out a few more hours too if i left it idle....not too bad

I find that Battery indicator doesnt draw much power if any as I've always used it and never had a problem. The maker of the app states it uses no extra power. I love the circular battery indicator version found in the market. Its not a widget, it stays in the upper left corner of your notification bar. You should give it a try.

Phone doesn't get hot. I've started from scratch twice, I've ##DATA# reset. I had terrible service and data speeds before I did that and it did a number on my battery. Now it'd fine, but it just drains while doing nothing.
I never use task killers or auto sync, I live with spare parts and and monitor it, no real partial wake usage to speak of. I know how to save battery, my hero get 20+ hours with use and auto-sync on.
I'm thinking my battery might be bad. Feels like your talking down to me too, captain.

I haven't had mine a week yet, but atm I'm not getting half the battery life I did outta my Hero running AOSP's Gingerbread alpha.
I'm blaming the crap bloat that's part of the stock ROM.
With the display set to 15-20% I've got the display accounting for 69% of the battery usage. :/
Turning off sync is not an option and I feel defeats the purpose of a smart phone. Additionally, I fail to see the point in paying for 4G and not using it. (I do turn it off if I'm out of area for it or don't expect to be using much data.)
So thus far I'm disappointed in the battery life... but still think it'll improve vastly once rooted and cleaned up.
EDIT: Just did a test running Angry Birds for about 10 minutes... maybe 15. It ate up 9% of the battery in that time. Added another 1% to the display usage.

I'm just trying to give advice so that other people understand what to do to get the most out of the battery. This wasnt meant to be just directed to you. Sorry for trying to help you out, Captain.

Miren's latest update last week is supposed to have "reduced battery usage". I've had no problems. Maybe time to come back to the Light..?

I was able to hit the 48 hour mark with light use.

hey that's really impressive. I thought my 20 hours battery life was pretty good...kudos to you.

def getting better bat supply. especially from my hero which only lasted about 6-8 hours, just got my shift yesterday afternoon. from a full charge: Constant texting, facebook, Zenonia 2 (Downloaded wifi), Snes emu + 11 roms (3G), and customizing it to my hearts content. almost 12 hrs later had 20% until i plugged it up at work.
so far this thing is a golden brick to me

Just out of curiosity, how do you calibrate the battery? Just in case my battery life doesn't match the reports (I know my luck )

Its under # 13 on my 3rd post.

getting great battery life isn't that surprising given you've got a 1500mah battery much like the evo and epic however 48 hours is rather impressive.
Sent from my cm7 Evo 4G!

Working on calibrating my wifes battery and damn this thing is hard to kill. Even with with everything running for 5 hours its still over 20% finally decided to bring out the big guns. Turned on navigation and the flashlight. I'll post when I see the battery life after calibration.
Sent from my cm7 Evo 4G!
Edit: Phone plugged in at 7:53pm PST. Now to see how long it takes to charge.
Edit #2: Phone finally fully charged almost an hour after my evo finished its 0 to 100 at 12:19am
Edit #3: Holy F***. This phone takes forever to die and to die. Finally on the second off charge. I wouldn't still be doing this but for the fact that its saturday.
