What the hell... Put my phone on charge last night around 8pm.... Left it till I went bed around 1am... So was fully charged..
Woke up this morning at 6:30 and my battery its down at 25% !
In the battery usage its showing cell standby used 35% and idle used near 40%..
Haven't installed any new apps lately.. Any ideas what's happened?
did you leave wifi on?
Not even active wifi should lead to such loss on power... at least if it's not used by any app in the background. Was the back of the phone warm as you held in hand? I experienced, that heavy usage can be also detected on the warming battery. If yes, you should browse the running apps and kill the unnecessary ones. And perhaps try to investigate the settings of the running apps.
Everything was the same as every other night since I bought the phone 3 weeks ago... I usually leave wifi on and it auto switches on or off when I get home or leave..
I don't recall the phone feeling warm..
Well I took the battery out and left it a couple mins .. Now it back up to full charge so will see how long I get this time...

If not already done so, you may also want to consider installing a battery saving app, like JuiceDefender.

Cool post Mas!
Actually, Im not using any battery saving app, but the Power Control widget you also mentioned is on my home screen. I think this does the job very well. Best battery saving app for me
No problem buddy. You should also give the Extended Controls app or Switch Pro widget from the Marketplace a try. Even they are both paid apps, they give you a selection of more controls, just like the HTC Power control app. One thing the HTC Power Control lacks is an auto-brightness toggle option, however, this and many more features (including theming) is available in both paid apps mentioned above... give them a try

Answer me this one then guys,
Phone fully charged, on flight mode, in sleep over night. Used 12% of the battery.
I'm really disappointed with the battery life of the Desire. I've set everything on the phone to update twice a day working day and manual after 5pm, Turned off the locate by GPS, turned off the constant internet connection and everything else I can really think off.
I hardly make any calls, it's mostly just sits on my desk with the occasional text. Yet still have to charge it by the afternoon!
It came off from a full charge just 2 hours ago and already down to 90% So that's 10 hours standby time!
Phone was picked up on Friday, so it's had a few days to gets used to it's cycles. What the hell am I doing wrong or do I have a naff battery?
Opinions please!

Hi Dan,
Running a Orange stock Rom. Could it be that Orange don't power manage very well?
I had seen somewhere already about the animated wallpaper draining power, so I've never had an one!
I'm really puzzled!

*Scratch head*
Not really played with an Orange ROM yet,,,, if your rooted why not try a different, more power handy, ROM and see how it goes, if all else fails and there is a error somewhere you can always flash back to Stock and make a return jobbie
Eek
My phone has been on for 19 hours now and it has drained the battery to 34%.
Now normally that wouldn't be all that bad, except I've had a 12 hour sleep and didn't do much with the phone except unlock the screen a few times to check the time and battery status.
Battery status tells me the following:
Phone Idle: 92%
Android system: 6%
Display: 2%
Airplane mode is on.
BT, wifi, mobile internet, account sync, background data and all that stuff are off.
So what is the big drainer in the phone idle catagory?
Think I have a similar problem but mine drains rapidly at 20ish percent on about 10 mins. If I charge it up to20% from 0 it will slowly drain as normal.

myself my wife and my son all have desires
my wife is the only 1 who has a live wallpaper and 3 nights ago i monitored her battery usage and over the course of 1 night her phoned used 7% of the battery.
mine uses more as i do more with it
Fixed my problem. If anyone else is wasting a lot of battery with " phone idle " try the following:
When phone has wasted battery during periods of not using it, type in
*#*#4636#*#*
then select " Battery History"
In this screen check what's sucking up your overnight battery by selecting: "partial wake usage"
For me it was weatherbug elite.
Got down from 80% to 70% this nights sleep so i'm currently very satisfied.

As soon as i get my Desire back next week ill try this, coz im havin same problems on a HTC Stock Rom, Normally its on my desk at work 7-7.30 hours nd goes from 100% to 50-55% so ill have to charge it every afternoon i get home :/
As I posted in another thread:
I am lucky to even get 12 hours with minimal use. No calls, just some texting and maybe browsing my bank website. Screen is always the killer for me, even on 20% brightness. If I go lower the screen actually flickers.
I bought the red HTC Chichitech batteries and they didn't help me at all.
Tried overclocking module, didn't change much.
The only app that ever shows any significant battery use (over 5%) is Maps, when I use maps.

I am rooted, S-OFF, using the Sense Modaco ROM. Battery usage was no better with the Stock Bell Rom before rooting or S-OFF.
My main concern is the screen flickering at low brightness. it's as if it's unable to decide on a specific level of brightness and makes me question if it's actually saving any power.
I set my phone to Auto brightness and I am going to see if that is actually worse of if it's on par with 20%.
Ugh - just realized there is another thread pretty much all about this. I thought it was a different issue. Still, does anyone know if there is a better batch of phones or something? I have a FutureShop warranty so it'd be easy enough for me to replace if it will actually provide a solution
No-one has posted anything, to my knowledge, about a different batch of phones having better battery life. I would check out the other threads about battery life (including those on the G2 side too) and see if you can get yours to last better. But it could just be something faulty on your phone/battery.
Auto-brightness would make it even worse..because there is some type of bug or something that isn't making it function like it should. I was also getting terrible battery life until I followed some of these steps: http://www.goodandevo.net/2010/05/20-tips-to-improve-htc-evo-4g-battery-life.html
Biggest killers are any widgets that are constantly updating..or facebook/twitter apps that are constantly updating. As well..i recommend SetCPU to underclock your phone when your screen is turned off. This should also help with conserving battery life along with some of the steps provided in that link.

I am considering waiting a month or so and then having mine replaced. Unless I managed to figure something else out. My HTC Legend had better battery life.

The reason I want to try auto or higher brightness is to see if lowering it was actually saving me any battery life. I am curious if there's a driver or display issues that causes it to use the same amount regardless of the setting. So far I don't seem to be running out any faster @ auto than I was at 20%, but it hasn't been a long enough time to tell for sure.
Also I am unable to do the battery tip for the evo because once I turn off the phone and go to charge it again, it's instantly green. But I am going to try it anyway even though it's green.
Since writing the first post I used the OC module to get my phone to 1.2ghz. I have SetCPU set to run on boot with the onDemand setting. I have a profile that says to slow the CPU when the screen is off. From what I've read it doesn't make a ton of difference with this particular phone, but we'll see...

Yep, that's what I found too, when you try and charge it thinks it's already charged and goes green straight away again. But as you said, worth a try.
I just wanted to report back and say that I had my phone replaced. So far so good:
- No screen flicker issue at low brightness
- Battery has lasted nearly 20 hours with moderate-heavy use (played NFS Shift, setup basically everything on the phone after rooting, installed all my apps, backups, flashed some roms, 20+ texts, 3-4 short calls, showing people random apps.)
If it's not all in my head then this is definitely much better now!
Curious. It seems that everyone who reports the screen flickering problem has poor battery life.
Defective displays?
I feel my battery life is pretty bad as well. I've unplugged the phone this morning at 7 AM. Now it's 2 PM, and I'm at 37%. In between, the only things I've done are: send/receive a few emails and chat on gtalk. Brightness is at 40%, animations are turned off, wifi and gps location off. Using latest Cyanogenmod (6.1.1) and have no screen flicker issues
Edit: 17 minutes later, it's now at 27%
How long have you had the phone for?
Initially the first few days I got the phone, battery life was really bad, could drain in a few hours.
After a week or two of use, I now have reasonable battery life, the phone can last all day with light usage and still have lots of juice left. Actually I think if you make a few calls and a few txts, battery could last 2 days. If you play with it, one day for sure but you need to plug in over night.
(if you're talking to me) It's quite new, just picked it up on Friday actually. Also I've kept on researching, and it seems that poor coverage (like I have at work, from 7 til 3) tends to drain the battery even more, since the phone keeps switching between HSPA, 3G, etc.
I had my first one for about a month at least. This replacement was from Saturday.
Today I've had my phone unplugged since 8am, it's 5:30pm and I have 45% battery left, but the screen is the #2 user. Standby is #1 @ 40% of my battery usage, due to over 4 hours of time without a signal. The screen is only 24% and has been on for 48 minutes. Voice calls is #3 at 23% battery usage, with 23mins of calling.
My other phone would have died by now.
Also I spent an hour of streaming bluetooth audio to my car. Bluetooth doesn't even register on the battery usage. I've never seen it use more than 2% and it's always on. I am not sure why people say it uses a lot.
Just want to share my experience.
I too had poor battery life. Stock Bell ROM. Got to 3:00 pm and it used to die. Use this for work. Pushing data all day from Exchange server, bluetooth on all day because I'm in and out of the car, talk on average 30 minutes per day, texting, surfing, tethering, blah blah. Believe it or not, my old Omnia II would get me thru the day no problem.
I was also tempted to return it. But I decided to try a few things. Installed Set CPU and a task killer at the same time. Shut down as many tasks as possible on start up. Widgets and accounts, except Exchange-push, run and sync every hour. I get about 40% battery by dinner. I am happy now .
I'm quite happy with my Desire Z's battery life, It lasts for about 36 hours with moderate use. I have Juicedefender and Ultimatejuice installed, data or wifi are opened only when an app needs data connection, this increased my battery life by 10 hours or sth like that. Nice app.
I had terrible battery life until I went overseas. It is a stock Bell ROM, but I arrived in Spain Monday and am using a Spanish SIM card.
My battery life has increased from 14 hours with Bell's 3G signal to my current 27 hours and 35% remaining battery using GSM and WiFi always on. Funny thing is that no matter where I am it says the screen is by far my biggest power drain.
Where did you buy your Desire Z and how did you get it replaced? I'm with Bell and they would take mine to send out for "repair" but not sure if that will do anything. This will take 3-6 weeks apparently and I'm not sure if they it is worth it.
I'm running 10 hours with that I consider fair usage (few calls, text, map/gsp, and facebook.) My display is the highest battery usage at 60% and on for about 1:45h. I'm very disappointed.
Hey,
it's the same with my G2.
Max 24h.
I've standard ROM installed.
No WiFi.
Brightness to about 30%.
Juice Defender is installed and I'm surfing and just the regular stuff, but even if it's just in standby, it's taking a lot of power (display takes most)
Best!

I bought mine at FutureShop since I didn't think Bell would let me without buying at least a month of service (or being an existing customer). I also purchased FutureShop's extended warranty which is how I was able to get it swapped for a new one so quickly.
I use the extended battery for the evo. Lasts about 1.5 days with ass loads of use. Just have to trim the plastic edges a bit.
Sent from my T-Mobile G2 using XDA App
I have a couple of those red chichitech batteries but I wasn't able to notice any improvement with the problem phone.
My Desire Z also has a flickering screen at lowest brightness, and with moderate use it dies after about 12 hours max. Even on lowest brightness the screen ueses 59% battery. I rarely manage to make it through the day without having to charge the phone. Im on stock ROM with latest OTA (1.72) btw.
Gonna have it replaced next week just cause of the flickering screen. Has anyone tried the 1700mAH battery from seidio?
Any help is appreciated...I'm at my wits end with this phone. I've been unable to make it through a day of work since I've had it.
I charged the phone from 1130 to 7 am, at that point i shut it down and did the hour charge, at 8am when I got out of bed I turned it on, let it run 2 minutes, charged it for another hour +. When I took my phone off the charger to head out the door it was 9:14AM. Its now 11:10 AM and it already shows 79% battery. I've barely used the phone. (trying the HTC tricks or just letting it hang normal both seem to make no difference really).
Spare parts reports 9m51s used without sleeping, and 9.4% used, 6.6% screen on, 0.6% phone.
Wifi, bluetooth, 3g, and sync all off since leaving the house. I've done nothing but send a few texts and listen to a voice mail.
I dont get the best reception at my current seating area, but I am able to make some calls / get service despite. Could this still be the cause? If so - is there ANYTHING I can do to alleviate that?
I have CM7 02262011 nightly, build GRH78C - on zendroid CFS. I thought zendroid would help with battery life immensely (as many reported) but I've seen almost no improvement. At this point, I'm not even making use of the smart phone features - no wifi, no playing games, no browsing the web...as soon as I fire up a game the battery plummets. EDIT to add I've had this kernel and rom for about 4 days now, and I did clear battery stats after flash. All I've read would indicate this should be enough time for it to "settle out". Is that true? END EDIT.
At this point the phone is virtually pointless to me....is the battery life that bad? I see users talking about 18-20 hours with light usage - I generally put myself in that light usage category and I cant imagine making that mark. Any suggestions?
If your "time without signal" in battery usage is really high, that'll eat your battery super fast. Really, having a low signal constantly will do the same thing. Because where I live & work never gives me more than a bar or -90 dbm, my battery goes pretty quickly too, even without a high "time without signal".
I keep 3g, Bluetooth, and GPS off almost all the time & keep wifi connected at home. I recently switched to 2.37.6.2-SavagedZen-0.1.2-CFS-HAVS-WiMAX-Froyo+. I unplugged the phone 8 hours ago (I don't like to keep in charging overnight) and it was at 98%. When I got up an hour ago, it was still at 98%. My time without signal was 73%. I've used it heavily for the past hour & it's at 95% now.
My battery life isn't great by any means, but it's better than it was. I also use CPU Boost (a free app similar to Set CPU but with less options) to undervolt. I slightly undervolt to around 700 MHz while using it lightly & set it down to about 460 with a screen off profile. Since I rarely do anything that needs the full ghz processor, this doesn't affect my phone's performance & really saves battery.
Hope this helps

It sounds like poor signal is hurting you.. your phone may be constantly searching for better signal and killing your battery. Just be sure you have no wakelocks...
Also, when you wipe battery stats.. make sure you re-calibrate your battery as well. When I wiped stats it actually did more damage than good until I re-calibrated the correct way.
Thanks...I'll try under clocking a bit and see if it has a gain...I had that disabled up to now.
I put on ZenDroid-1.1.0-cfs-avs... (about phone shows it as 2.6.35.10ZenDroid) with anywhere from -96dBm to -104dBm. Could that be the explanation?
I'll have to monitor a bit more closely at home to get a better idea of service and battery consumption.
Thanks for you input and help though.
Anyone else able to comment on their signal strength and relative battery peformance?

Could you elaborate on wakelocks? I havent heard of this before... (ill do some searching as well).
Again, could you possibly comment on re-calibrating? I was under the assumption that was letting it charge fully and drain fully after a wipe of stats. I wiped stats on a full charge, let it run down, and then charged back to the phone reporting 100%. Was that incorrect procedure??
Thanks for your input!
Have you let the battery drain and than recharge several times? Part of letting the phone "normalize" for a few days is letting the phone go through several charge and drain cycles. If you get "scared" when it hits 60% battery and plug it in, your not allowing the phone to properly calibrate your battery percentage.
Also, go into spare parts and your battery history and find out what is under "partial wake usage". That will let you know what is being used when your screen is off.
For comparison sake I'm on CM7 RC2 (same results w/ RC1 though) and savaged zen 0.1.0 CFS SBC. I have one push email account, sync always on, wireless data on when no wifi, no bluetooth, and no gps. My screen brightness is always at 25%, which is plenty bright. I also have several apps running in the background like weather update once an hour, kakao talk, gtalk, etc. With Wifi on at work (NOTE: wifi saves TONS of battery over using 3g), I unplug at 7am and at 11am I'm right around 90%. A few texts/gtalk and about 30 minutes of web browsing since unplugging. I generally leave work at 5pm with around 70% battery left. However, after I leave and start using the phone more battery does drop pretty quick. I can usually make it to 11pm, but I use the remaining 70% in those 6 hours as opposed to my "work battery" which is only 30% in about 10 hours. When you start using the phone you are going to get fast battery drop. The large screen and fast processor are the culprits of that.
Always keep in mind. You have a mini computer in your pocket. You are not going to get days of battery life like you would with a crappy flip phone. Laptops with gigantic batteries last 4-6 hours, and your phone is doing similar work on a much smaller battery. It's amazing these things can get 20-24 hours of use.
Well after poking around in spare parts at the prompting of you all, I found that my phone was without signal for something like 81% of the day. I put on airplane mode and put wifi on and i was seeing normal drain. Oddly enough, it seems my HTC Hero was able to stay connected to the network better in the same "office location" - as I didnt see that kind of drop.
Regardless, its no big to kick on airplane mode for most of the day and fire up normal service on short breaks or whatever else. So issue resolved all in all. I appreciate the assistance prompting me to look into the spare parts and its various features.
Again, with airplane mode on my numbers are MUCH more inline with that of other users. Thanks to you all!

Yea, just gotta watch out for bad signal areas, as those are the biggest battery eaters. Some phones [of the same model even] handle areas differently than others. So if, like in your case in a bad area for extended periods of time, kick on airplane mode. Also like also said, turning off your 3G when not in use is also a big battery saver.

Ditto! I wiped stats without knowing what they did, found that it got WORSE. Then I looked up how to actually calibrate. My battery life rules now
I also found that calibrating your battery helps. I realized that if I unplug and then plug my phone back in almost immediately that it has to charge a little more to get back to 100%. If you do a search for calibrating EVO battery you'll find detailed instructions.
Im getting some weird battery stuff, as well as the Android OS drain. If I restart my phone, once in a while It drops like 20-30%. i'll go from 46% to like 18%. I see the threads about slow draining, but mine seems to happen instantly sometimes (3 different times so far in a week), anyone have solutions? Got it from someone on ebay, can I still/should I RMA?
Someone posted a kernel fix in the international GSII forum, so we're either waiting for that to get ported over here or wait for samsung to release a fix. I have that same bug too. What percent r u getting on the Android OS? Mine is usually in the 60's.
Yeah I saw that thread, and I saw the 2 things causing it. Waiting for that fix I guess, hopefully it solves the big battery drops as well as the small draining. Mines pretty high, 30-50% I believe, and then cell reception takes 10-20% with LOS
That's alot better than mine. Although, I don't have that LOS problem. I'm running stock atm. Are u on a custom rom?
Running Starburst 1.5, stock was better for no LOS. But I like the customization on Starburst. Hopefully by the end of this week the kernel we be ported over.
Most likely a problem with the battery level algo and not an actual battery charge drop. It's probably showing the correct value after the reboot.
Using battery spy I was using like 12%-15% per hour, not even doing anything. Saw online that formating the SD card might help, just did, and now im using .8% per hour. The hell, something was scanning the SD card or something. Much better now, hopefully itll last 10-20 hours instead of 6 hours.
edit: so it went back up again. At .8% it will last 2 days+, but since the events keep taking the CPU, its draining it. I got it down to 4-8% by taking the SD card out. At least it will last a little longer. Cant wait for the fix, this baby will last days after.
Damn that sucks. I just formatted my card too cuz I was running out of options. Keep us updated tho.
so I think media scanner is draining, I downloaded rescan media root from android market and before I was draining at 12% per hour, but when I disable it with the app, it goes down to 5-6%. Anyone else try? Maybe thats something thats draining.
Oh btw have u tried turning off wifi? It only drained 6% after being off the charger for 9 hours. I havent touched the phone during that time span tho. Android os still in the 50s btw.

this is almost definitely correct. battery doesn't drop 15-20% because of reboot...the reading is wrong. Battery drivers have been bad on a few of the latest android phones. Just look at when your phone stays at 99% for the first 3 hrs of use each day...what, does it just get really inefficient in the afternoon because of food coma from lunch?

Trying now, seems to be charging faster too. I was mainly on wifi because cell standby was really high, keep getting LOS. But maybe I wont with wifi off now, and i'll see how battery does. ill keep you updated.
Still bad. Can only wait for the patches/fixes. 8 hours doing nothing almost. Sigh.

Hey man, I got one more tweak for u to try. I just rooted my phone w/ the latest zenomax kernel and Starburst 1.5. Download setcpu and create a profile for "screen off". Set it to 200-500mhz on demand. In theory, this should prevent 100% cpu utilization while the screen is off. I'm testing this myself atm, so I can't give u my battery stats yet.

Set it to 200-500mhz on demand. In theory, this should prevent 100% cpu utilization while the screen is off. I'm testing this myself atm, so I can't give u my battery stats yet.

Think I have the v3 version and 1.5 as well. I have setcpu set to 200-400 powersave. ive tried others and same. Suspend and events/0 keeping eating at the CPU. Thanks for the suggestions though.
figured i'd chime in here. i've had days where the battery was fine and days where the battery was absolute trash. it's happened on stock, and it's happened on root. but it almost always seems to coincide with LOS. the first picture is one of several instances where i've had pretty fast drain followed up by an instant dump in charge under normal use. it's strange how after the drop, it slowly works back up then levels off and drains normally. the 2nd pic is from today. i left my phone at home on accident when i went off to work, and when i returned, i had LOS and this battery stat. you can tell where i lost signal . the last pic is from yesterday while i had the phone at work all day and light use; a nice consistent drain.
FU battery drops and FML
Ok so i read all the posts in this thread and i understand theres a issue that effects the phone from even knowing what the battery % is. i had to post these though. i was at 47% then rebooted my phone. phone boots up and yehhh! woop woop 8% now mind you if you look at the graph it shows a nice constant cerve downward but steady because i was using my phone the entire time. now after the restart/batery drop of 40% i kept using the phone constantly but its funny how it took me over a hour of screen on to go from 8% to 5% !!!!! i bet to get from 5% to 1% it will take 2 more hours for sure. you can see the graph start to flatten out like its a super battery after the 40% drop because it didnt really drop to 8% !!! normally i wouldnt care since my phone battery last just as long, it just goes down really slow from 8%-1% but at 5% it auto dims screen and wont let me use my camera for the next 2-3 hours while i knock off the remaining "4%" of battery left. fml
Get Starburst v1.6. He removed DRM processes which should lower Android OS usage and thus battery draining. Plus with the LoStKernel, I haven't had any issues with losing signal since.
Also, use Titanium backup to remove running services that you don't need. I got rid of the stock email client, digital clock, media/social hub if you don't use those. They don't take up a lot of ram, but every little bit helps.
My battery life has improved after battery calibration. I suggest you calibrate if you didn't already so your battery usage graph may be more accurate. Hope this helps.
Thanks for the tips! I was wondering how you would calibrate the battery. Is it the same as wiping battery stats from CWM?
I have the Sprint Galaxy s6, which is fine phone, except the battery is awful. If I unplug it from the charger at 6am, it's down to 12% by 1. Would a new rom help? I haven't rooted the phone yet, but if it'll improve the life of it I'll do it.
Just some input, I had an issue with the voicemail app the other day. After googling it, I found it was an issue on Samsung phones right now. You can look under battery setting to see if it's causing you issues. I'm rooted, so I disabled the app. But it killed my battery overnight, which has never happened to me before.
I use the Renegade rom. It says it patches some deep sleep issues, I'm not 100% sure what that means but it appears to help battery drain when the phone isn't in use. I also use the Unikernel kernel. I'd follow this guide to get rooted and install a recovery (this will trip knox, but if you're thinking about a custom rom you probably don't care). Backup your stock set up, then install the rom I named above (or any rom you like). Then use titanium backup to remove all the Samsung/Sprint bloat. I also use Greenify and apps that take advantage of the S6's AMOLED display (awsms, baconreader, etc.) Here's an AMOLED theme, too (use the Black Mod). I know that's a lot of time and work that shouldn't need done to get good battery, but if you want decent battery that should get it done. That's what I did and my battery is better than stock (usually lasts me all day with just short of 5 hour screen on time). Hope this was helpful!
Thanks for the advice. I've read that Android M is going to help with battery life, so I don't know if I should wait or not. (I probably won't)

in my experience the best thing that you can do to increase battery life is to remove bloat. That is why i use a heavily debloated ROM, and even with that I remove apps that I don't need.
Beyond that, I use Greenify and Wakelock Detector.
Except for heavy use, I typically can run my phone all day without needing a charge. That is all that I really need.
I've got a similar problem.
I factory reset recently, and just let my phone sit with nothing but Google Messenger and Facebook. It still dies from a full battery in ~4-5 hours, without me touching it. Thing is, all the battery stats show less than 5% usage. And there's no crazy crap like games, etc running. I can't figure out what's eating the battery.
I just put the phone in Airplane mode, and enabled Wifi. I'm getting all my emails, fb messages, gmail, google voice, so on. Battery only went down 30% in 28 hours. I turned off airplane mode (it's not connected to Sprint at the moment, I took it off the account), and I have an Airave...battery dropped 15% in about 30 minutes. Went back to airplane mode with Wifi on, and back to a really slow drain.
Right now, I'm planning on packing up my phone tomorrow and sending it to Samsung for a battery replacement. Because my standard 2A-5V can charge this phone from 10% to 100% in an hour...which isn't right.
