Battery doesn't last long. should i change it?

Ok, my battery is weird it doesnt last long. it dropped from abut 95% to 70% over night, with checking email every 30 minutes with k9 and the mail app every 4 hours. My phone doesn't last very long either, I haven't tested it fully. I always keep charging it, when im in the house.
I bought it from T-Mobile and i could swap it. Should I?

Might be worth it, I have Friendstream updating default setting, Googlemail (although it's push) on at all times, browsing a fair bit (on mobile net and WiFi) and a few calls and it last 2 days-ish...I'm using a generic Desire on latest FW

Mine's the same. I didn't think it would be worse than my old BB Bold for battery life, but it really is very poor. I don't think you have a fault, it's just the way it is.
I wondered about closing background apps but I've read that having them open doesn't impact battery life. I do have a few background things going on though that will affect it, so maybe I need to consider if I really need them or not (frequent email syncing, contacts/calendar syncs, etc.).

Have you put the phone down for long periods in-between uses, or have you spent a fair time writing emails or just playing with it? I've spent a fair time on mine but not constantly, and no more than I used to with my BB Bold. I used to writing emails constantly on my Bold and the battery would last a good day, but until I'm used to this keyboard I won't be doing that on my Desire.

So It won't make a difference if i swap it? I also didn't do the standard charge at the start. Couldn't resist playing with it. So It was on charge while playing with it. Could that make a difference?

I'm in work a lot and I'm not constantly on it - just check for emails/SMSs every hour or so so prob spends a lot of the time in standby. I'm on it more on the weekends but it still lasts well into day 2

If it works otherwise then I doubt there is a fault that would cause the battery to run down but nothing else not to work.
Not charging the battery at the start is one of those things that some say makes a difference, other say it doesn't. With Lithium-Ion batteries I always thought they didn't need that initial charge, but I can't say for sure. Anyway, what might help is if you did a full charge then a complete discharge (use it until the phone turns off) then a full charge again. With older batteries at least, that tended to help them last longer.

There a a few threads on this alread here and on the Android Forums.
There is a problem where the phone when charged left on, only goes upto 98%. However the phone will soon drop to 90% and lower quickly, indicating the phone has not charged properly.
If you unplug and reconnect, it will go back to 100% but almost as quick as tying your laces, it will go from 100 to 98% and continue to drop.
It could be faulty batteries.
I was hoping the FW update would fix but it hasn't as I found out last nite.

Or should I just buy another battery?

I've been having similar issues,
I get much much better battery life without mobile networks on, and alot of application crashes/phone reboots to get it work like I expected.
Took some data:
1hr of phone in sleep mode w/ mobile internet on = 4% battery
1hr of phone in sleep mode w/out mob internet on = >1% battery
So I can get a good two days if I don't have any internet with moderate use, but about 16 hours with internet always on and moderate usage. If I really 'rag' it and use alot, I can get about 50% done in a few hours (not constant use either, just alot of google goggles mainly!)
This coupled with the crashes and reboot made me get an exchange, I'm just hoping it's better, and really hoping its not worse..
Wish me luck, I wish you all the same.

After couple weeks my original battery seems to last longer - I do with 1,5 days now (with some browsing, 3G, occasional GPS and bluetooth, weather & gmail sync, dl apps from market etc). So it might be true that after the initial couple weeks of usage and charging the battery performs much better.
Intrestingly T-Mobile promised to send me a new battery over a week ago. As it never arrived I called them and was told they dont have any... but they would credit my account with £20 to buy one. Today... I received an extra battery from T-Mobile!!! No idea what is going on - and if I still have that £20 credit in my account
I will give that new battery a loooong first charge, see if it helps.

what about the 3000 mAH batteries?
Are they any good and would it work for the Desire?

Won't help, once it's at 100% the charging will stop. There is no such thing as 'long charging' li-ion batteries or 'trickle charge' a li-ion battery.
You can try to do a full first charge (until the green light burns) and then fully discharge (until the phone goes off). Then fully charge again. This will calibrate the battery chip and make sure you see the correct percentage.
If battery life is still no good then it's because you use the phone too much. Read: constant weather updates, friendstream updates, push mail and other stuff that constantly use the mobile connection. Also turn off gps unless you need it.
Turning off those services and turning off the 'always on mobile connection' can double your battery life (read: standby time).
It's not something magical, it's completely normal. If you want the phone to do a lot, it will obviously use a lot of battery.
Just for the sake of it, put the phone in airplane mode. You will be amazed how long it will last.
It's the main problem with modern mobile devices. Battery usage and capacity are no longer in good balance. What we need is more compact batteries that have more capacity.
At the moment it's clearly a comprimise between battery size (thus capacity) and battery usage. It's up to you to see how much you want to comprimise.
And so far, with every HTC phone, after a few (radio rom) updates battery life increased.
And... what everyone seems to forget, when you first get your phone you will fiddle with it.. a lot.. And once you have it for like a week or two, you start using it differently. Usually ending up with better battery life!

Try to run it down to around 5-10% after each full charge, but don't let it go completely dead if you can avoid it. Do this a few times and you will notice an improvement. Plus of course, when the novelty wears off and you use it less the same will happen.
Back when I got my Touch HD it would only just last a day, but by the time I was on the upgrade path I could get 3 or 4 days out of it!

Just to confirm, I was a bit worried at first about the battery life of the Desire. The first 2 days I could only manage to get 7 / 8 hours out of it. When I turned data sync off at night, it still lost 40% of the battery .. doing absolutely nothing.
However as mentioned before, I'm now on day 6 and now I can easily get 36 hours of browsing / texting / calling 2 hours + / even playing occasionally games. At night, without data sync, it drops just 4%.
So if you're worried about your newly acquired Desire's battery sucks, It really needs some calibration. After a few days it'll work as you wish.

T-mob battery
Hmmm.. Not sure what T-mob is up to. They promised me a £20 credit to by a battery (they didnt have any in stock) then I received the battery in post. I called 150 and they confirmed the £20 credit is still there for the next bill...
I couldnt be happier with T-Mob! Besides this I got 100txt/100min, plus 60 min included to Eurasia, Internet and 40 free txt to Europe = all for £10 a month!
Now I just need a case for it... waiting for the PdAir one to come, had one for my Compact IV and loved it. Its the flip one that opens upwards not down, so wont mess with the hardware buttons.

I really hope that's the case...
I got my Desire on Tuesday, first use was on Wednesday.
Yesterday (Friday) I put the Desire into Airplane Mode - I deactived everything. Turned off WLAN, mobile Internet, Syncing off manually before I went into that mode, just to be sure. When I went to bed, I had 72% battery left. When I woke up...50%...seriously, what the f...?!?!
8 hours of doing absolutely nothing uses 22% battery?! It's really annoying at the moment, absoluetly unusuable unless I'm home and know I can plug it in any second. When I'm out, I don't even dare to use mobile Internet, because even without it it only lasts till I get home (no WLAN, no mobile internet, just using it as a "telephone"...).

You expect the phone to stay turned on without using any power? This isn't a dumb phone, it is running powerful components and 8 hours doing "nothing" is relatively long time and the power usage of keeping those components powered at idle levels is going to add up no matter what. If you can't bear to turn the phone off if you can't control your usage, carry a charger or battery you should have got a dumb phone.

Bear in mind that the full capacity of the battery won't be reached until several charge/discharge cycles have been done, especially when you are using the battery for the first time on a new phone or on a phone with updated firmware. I noticed this while flashing custom ROMs on a previous handset. I'm sure we will also notice improved battery performance when firmware updates become available.

Insane Battery Drain issues. [dying in <4 hours]

Using battery optimazation processes like juice defender, and even having advanced task killer working, lowering my brightness, and otherwise just having everything turned off like wifi, GPS, and all that business, im still seeing OUTRAGEOUS battery drain,
using the cyanogen nightly build.
this morning in 25 minutes
lost 16 percent battery
after coming off a 6 hour charge..
So.
the question is.
Where to start?
What to do, my phones just not makin it, its dyin all the time.

There are a few suggestions i would make. Just for background information have you used other Roms and if so was the battery ok for them or is this the first custom rom you have used? (just to compare to see if it is a new issue you are having with CM)
ok first i would get rid of the task killer. they do more harm then good Android will auto kill tasks and MANY of the tasks it kills are just stored in memory and are inactive causing little to no actual battery drain.
you can turn GPS back on it doesnt drain battery when not i use and can be useful to ahve on if you lose your phone.
If you havent done it yet search the forums and download SetCPU (or get it from the marketplace for a small fee) there are several posts about battery saving profiles on the forums or you can find one here.
A good post that has worked from some is to turn enable always on mobile ON (if previously turned off), turn auto sync ON (if previously turned off) TURN news / stocks/weather - OFF but keep your single google account turned ON.
I have no idea why or if this would work but have seen posts saying when they did this it did actually help.
If you havent tried to re calibrate your battery or the HTC charge method yet i would try hose as well (calibrate by charging to full draining it all the way till it shuts off then charge it back to full with out interrupting the charge.) The HTC charge method is to 1)charge the phone 8+ hours 2)unplug it and immediately turn it off 3)charge it for 1 hour. 4)power the phone on 5)unplug it for 2 minutes 6) then charge it on for another hour.
If you still arent getting very good battery life you can look for the app SystemPanel, if you purchase the full version you can get a history and see the top apps draining your battery (should let it run at least 24 hours while you use the phone normally so it can build data) this should show if you have an app that is hogging the battery. After all this if you are still having problems then you may try another rom or you may have a bad battery.
If i had to guess if this is a new issue i would bet that since you wiped to install CM6 you lost battery stats so a calibration and htc recharge will greatly reduce the problem.

your reply absolutely kicked ass, ill start trying all your suggestions tomorrow, im so happy i got an amazing answer from someone here and not flamed for being a dumb noob.
thanks again!

1. Get rid of CyanogenMod, flash Snacks 9.7 or DamageControl 3.2.3
2. Get rid of task killer
3. Turn off 4G/Bluetooth/GPS

To tell you the truth get rid of Juice Defender. I have never found it to help at all. It could even be the thing that is killing you. Get SwitchPro and and add the data connection to the widget. If you turn it off when you aren't using the phone, I have gone 2 hours without seeing 1 percentage drop. Just tapping a button to turn it on when you need it is nothing, and it takes about 15 seconds to reconnect. Juice defender is supposed to be doing the same thing while the screen is off, but as I said I don't think it works.
Other than that like Omega said, SetCPU really helps especially when you have the screen off if you set up the profile for everything. His advice is pretty solid, I just found another battery recalibration to work better which is to charge it for 8 or more hours with the phone on, unplug it, and then shut it off. Then plug it in and wait for it to turn green again, and unplug it wait for the light to turn off and repeat plugging it waiting and unplugging it 10 times with the phone off. Each time takes only about a min or so.
And there is no reason to get rid of CM, I use it and get equal battery than I did with DamageControl.

No problem at all i did a LOT of research and fiddling before i got my battery life to a level that i found sufficient. I use batterydefender/ultimate juice add on and it does turn off and on my 3g once set i had it set up right. Juice defender says i get x1.6 battery life right now according to it. I will say when i had juice defender alone it never said anything but x1 so it may be the add on helping. According to SystemPanel it uses almost no battery power (over 2-8-24 hours all show under .1% to give an example swype shows .1% and i do roughly 40 texts a day and very little keyboard use otherwise) so i dont think it is the main cause but you can always try the suggestion to turn off/on data yourself as well.
Any way let us know how everything works out for you and if you are testing each one at a time what made the biggest difference (i did almost all my battery saving stuff in bulk so no idea which one gave the most benefit for me just know doing all of it worked lol)

JPC battery life

I know it ibeta before you all start on me, however 15 minutes of web browsing = 10% loss of battery. At that rate my phone will be dead an hour and half of web browsing
When the phone is just on stand by battery life is fine
Hope they fix this when the "official" release comes out

Wow where did you learn maths?

if you need good long working phone buy something else like :hmm: i dont know what maybe NOKIA with small BW display

I noticed on the JPC the battery drains soooo fast!
did a full charge while the phone was off today and also deleted the battery stats.. lets see if it improves

I get 2 days of moderate to high usage with JPC. I think it uses less battery because the GSM signal is better, but the screen uses more power, is always over 90% in battery stats.

For me it all comes down "display on" time.
if using 3G/edge i get 4,5h
if wifi then 5,5h (no difference if im using it during 1 day or 4 days)
JPC is same as JP3 or JMx

Screen brightness
Just thought I'd say, incase you didn't know, the web browser has it's own brightness setting. That could be killing the battery.

I, for one, already set the brightness to the first level for all aplications that have brightness setting, and still the display sucks the battey like crazy, at list with JPC. With other FW it drops even to 40%.

Battery drain was ridiculous with me. The first night I went to sleep I remember my phone was nearly fully charged, when I woke up at morning it had used around 50%... that is, 50% of the battery for around 6 or 7h just sitting in IDLE! When I actually USED the phone it could barely handle 10h with a full charge, and that's with very moderate usage. I had to leave the phone charing all the time to survive a day with it (charging in my car, charging every time I stopped near an AC outlet, etc). And yeah, the funny thing was noticing how exaggeratedly high the screen battery drain was, even though I wasn't using the screen all that much...
Some other symptoms of the high battery drain:
-Charging the phone took FOREVER with the phone being used, took a LOT of time with the phone sitting Idle, but if I turned the off the battery would actually charge very fast... that proved that the phone was draining so much energy even the AC charger (or USB outlet) couldn't effectively charge the battery while supplying power to the phone...
-The phone got HOT very easily...
How did I solve it?
Well, yesterday I decided I would reflash my device. I did a full reflash (as I always do) including a re-repartion. Now the funny thing that I noticed was that my phone actually wouldn't flash! It would always crash at the Galaxy S welcome screen... I have never flashed it using my notebook (since I'm traveling), but I used the exact same procedure I always use with my desktop back home, for some reason it wasn't working. Maybe some corrupt file? I re-downloaded ALL files (that is, Odin with the 803 pit file, and the JPC files)...
For my surprise, this time my phone hanged in a green screen, and it was really scary. I even thought perhaps the Nokia USB cable I was using was causing some kind of incompatibility problem, but that would make no sense at all... so I entered the recovery menu in my phone and reset EVERYTHING, and tried flashing it one LAST time (this time closing ALL background apps in my notebook, to avoid any problems)... and there it went, a perfect flash, as easy as they go with my desktop PC back home.
1st thing I did was a hardreset, and then I reflashed it again with Doc's RomMod V2 (was using V1 the day before), and new hardreset in the sequence. Then I changed as little as possible in the phone configurations, I just turned everything off (GPS, wifi, and even the data connection through the power button shortcut), and went to sleep...
For my surprise, the next day I checked the phone's battery use, it had drained only ~4-5% for more then 10hours, this means it would, at least in theory, be able to last for days and days in this setup...
So I installed my apps again (not that I have many), did lagfix, turned widgets and network connection back on... and it has been working like a breeze, although battery drain can still be considered high, it's nowhere close to being as bad as it was before I flashed it, now at least the battery will last a full day with a charge @ my standards of usage, that's good enough for me...
One thing I did change, I remember my screen setup was always at 10/30min for shutdown, I left it like that because I'm always using the phone in situations where the screen will constantly shut down at my face, and that annoyed me... well, this time I actally left the stock 30 seconds for screen shutdown, not sure if it has anything related, but one of the things I noticed before was that my IDLE battery-drain was as high as you'd expect from a phone that had it's screen on all the time... maybe some bug makes the phone drain screen power even with the screen turn off, let's say if you have the 30min turn-off config, your screen will continue to drain power for 30min (and there you have the reason for so much screen draw in the stats), even though the screen is turned off... despite my hardware knowledge telling me that a black screen should NOT be draining power from your phone battery, you never know how far a software bug can fck things up hardware-wise, so I wouldn't be surprise if that actually DID happen...
I could even try setting my screen back to 30min-turnoff just to check if the battery drain will go back to insane levels.. but the fact is that I'm scared of messing it up again, it's working fine the way it is, why mess it up? I figured out some things that get messed up with this phone appear to only get fixed with a new firmware flash, and I really don't feel like having to flash my phone every two days...
Either way, I hope others here can fix their battery drain... it's just my tip: try reflashing, leave everything as stock as you can (only thing I did was Doc's RomMod v2, and later Ryan ZA's lagfix, none of them seem to be related to JPC's battery drain), and see if it helps...

wth I can only get 3.5 hours max
Sent from my phone so excuse the spelling errors

After a week of using JPC I don't see any real difference in battery usage from the original stock rom and JP3, I charge the phone every second night ( battery is usually around 25% at this point).
My usage isn't that high, I have a couple of notifications running and a weather widget that updates hourly, its my alarm clock, my mp3 player to and from work (about 90 minutes a day), I make and receive 4-5 calls a day and send and receive a dozen texts a day, I check face book 3-4 times a day and on a daily basis someone gets a 10-15 minute demonstration of the beauty of this phone(note: don't let a taxi driver play with your phone whilst in heavy traffic, even if it gets a confession that it makes his iphone look like a piece of crap).
As far as screen time outs are concerned, I set mine at 1 minute but always turn the display off manually when I finish doing something with it including after I have started the music player (btw I use bluetooth headset to listen to music but not for phone conversations).
The highest display percentage I have seen is about 85% but the is usually tied in with using gps or browsing, on a day I don't use gps or browsing display is much lower, on a day that the display is pretty much off it drops to about 10-15% usage.
This phone is the first, of the several pda/smart phones I have owned over the years, that I haven't had to charge every day.

Id battery usage is not a problem for me on JPC, 8hrs idle ( sleeping ) and I still got 100% started to use the phone and it rapidly dropped.. now im playing a 2hr movie and see if i can get it to loop for 2-3 times before it shuts off.. if it reaches 6hrs then i would consider the battery usage the same.

Please turn off the GPS and a-GPS....
You will get a much better battery life.....

enable always on mobile data?

anyone know what this does? i would imagine this would help a lot with battery life. but would i continue getting push gmail through my gmail app?
would there be any issues with my weather and calendar syncing (set to every 4 hrs)?

nvm.. not helpful at all. left this setting off overnight and lost about 15% over 4 hours..

This setting is actually very helpful for battery life...
what it means is, when u have it checked as on, 3g will keep connected while the phone is in sleep mode.. if turned off(without check mark) it will turn off 3g while the phone is in sleep, I think after about 10 min or so, and will kick back on as soon as you take the phone out of sleep.
I use this and helps very much. you can also set wifi to turn off after 15 min of sleep time which also saves battery.
I literally get 3 days with my inc2(Very light user when this happens.)

hmm maybe further proof my phone is defective.. good thing i have a replacement coming in. because i actually saw worse battery performance with it off than leaving it on. went to bed with it at 95%, wake up to 80%

Just curious....what was wrong with your phone that you had to get it replaced?
And that 15% wouldn't be abnormal at all if you had an app that ran too much. You should try SYSTEM PANEL app from market. Its awesome to track every app and how much juice its using.
Yup...Tapatalk'd

bad battery life. i have nothing running in the background. gmail autosynced and weather and calendar syncing ever 6 hours. that should not result in 15% over 4 hours with screen off.

Stop using the light and orientation sensors. So turn off auto-rotate and don't use auto-screen brightness. Also use wifi when possible; 3g will consume more power if your signal is weak.

Batter
It is not good for me either. I am loosing about 15% a hour with the screen off and not even using it. If I use the phone i can just watch it fall about 1% every 5 min. I don't get it. the only thing i have in the background running is weather, twitter and gmail. That is it nothing else. The Android OS sits about 86% use in the batter use screen. I have no idea what is causing this. Any help would be great.

Run the phone down completely, to the point where it shuts off. Then charge until the led turns blue(fully charged), then turn it on. I'll screenshot my battery status tonight.

Yes it is always posted that high. I have also already tried the suggestion of completely draining the battery and charging to 100% twice now. Doesn't seem to help. This is not my first android phone so I have tried all the typical turn stuff off. I started with the hero and then went to the evo. Then jumped to verizon for thunderbold and now back on sprint for this phone obviously. So far this is the worst battery life I have had yet. Seeing what you guys are getting though gives me hope.
I have tried using spareparts to get more battery information but get a force close when trying to do that.

Man I know that battery results range pretty wildly, but I'm averaging 10% loss per 2 hours.
On launch day I was on it from about 3:30pm until about 10pm and only lost about 40%. And when I say on it, I bet the screen on time was 95% of that time.
So far, the battery life is one of my favorite things about this phone. First time I've felt comfortable enough to run a live wallpaper.

You are lucky then, If i use the phone I will loose 40% in about 2 hours no problem. Also if you are loosing about 5% an hour that will only give you about 20 hours total before your dead. I see people reporting they are getting over a day. Just don't see how. Are they just not using their phone at all.

What does everyone have there screen brightness to if not set to auto brightness? Also what is everyone's screen mode set to?

I have mine at manual and just under the A. I have the mode at standard.

What I do is look at my active app widget to make sure I have no apps running. It is nice being there. Messaging sometimes hangs, I have noticed that.

You SHOULD always when you get a new battery fully Drain it and then fully charge the battery with the device OFF. Thats what I did with my phone. I kept using it once I got it, it lasted around 5 hours before the phone shut off during a phone call. then when I plugged it in to charge, I plugged it in and did not turn it on and waited till it fully charged with the Blue Light. I dont know about the normal thing now adays with lithium ion batteries but you were always warned in the packaging to let your battery fully cyle its first cycle with no use at all. The cells in the batteries have a memory type of design and if you dont fully charge the battery you can prevent it from knowing its full capacity.
Now I dont know if this is true anymore with the new battery production of the manufacturers now may power cycle the batteries before they seal the whole package so the customers dont have to do it. Maybe why when you get your device the battery is around 50% now like mine came. I remember older devices you could not use your device until you fully charged the battery the first time.
About Screen Brightness, I learned from a Epic user that the best way to conserve battry usage was to always keep your Screen Brightness at 10% (Gotta love the Touchwiz Brightness Changing with the Top Notification bar, this device will not show the slider bar like Touchwiz 3.0 on the Epic but IT STILL WORKS!!!!). I have noticed that at the lowest brightness setting I can still see everything vividly enough to work with it and im getting over 24 hours with moderate normal usage (like only 1-3 5-10 minute phone calls, surfing the net, surfing for new apps) This is my first android phone. I also have had 4G turned off and Wifi off all this time as I have no way to access those right now. I also have GPS turned off because I havent needed to use it yet. I pretty much have everything but Basic needs turned on besides all the Factory default presets. I also Turned my screen mode to DYNAMIC, which seems to show more vivid colors like I use on my Samsung TV for my computer usage.
Now I turned off Live wallpaper and im using one of the preinstall basic Grey ones (the one with the asfault looking spot light) (I have been trying to hit the crazy benchmarks people are getting trying to find out why I am not getting the 93+mflops mine keeps hitting 80's) So I dont know what heavy usage is doing to my phone.
but then again this is only under 48 hours of ownage. My first full night off the charger was 1 day and 3hours before it said I was 5% battery life and I plugged it in.
