Any pointers for increasing battery life? I've disabled live wallpapers, picked a dark background, set friendfeed etc to update every 4 hours, and it's still not great. Phone is new, should I expect battery life to improve as battery gets used a bit?
Are task killers worth using? Seems to be some debate that they might actually cause more problems than they solve.
I've gone through forum and found lots of generic advice but would appreciate any ideas people have tried on the Desire.
Do I *really* need to wturn off wifi when I'm not using it? Isn't the phone smart enough to not use it when a known-network isn't present?
Cheers
From my experience i would advise against having a task killer running.
I used to have one running on my N1 and thought, "Great, i can free up memory". But you really don't need to do that with Android.
Having disabled it from running, I get to teh end of the day and I have between 75 and 85 battery, after having done a fair few phone calls, some net fun and data access.
I still have a task killer but I use it infrequently and dont have it running - i let it "kill" itself after running it.
I found they take up a good deal of battery life. But that's just my opinion.

Of course!
The classic task killers kill services that are sleeping and do no eat battery.
A few minuts later, on some receivers ( connexion to internet, message or SMS received) these services will restart, and that's where they are eating battery.
If you hadn't killed them, they would have done that without eating battery.
Waking up and then going to sleep is really less battery-eater than restarting the whole service.
So, please forget about all these task killers or do that in a smart way. Only kill your game or the latest app you used!
Battery life will improve over the first weeks use. Needs a few charge cycles to achieve full capacity.
Although the battery life might not be as good as some other "imore ipopular" handsets at least you can buy a second reasonably cheap battery if you know you will be a couple of days away from a possible charge (camping etc).

You serious? I am guessing you're referring to the iPhone, the smartphone that is on charge more times than its off charge?
My Desire hands down beats an iPhone for battery life by almost 100% - only ever got 1 day of an iPhone at best - Desire is approaching nearly 2 days full usage, I am no lite user either.
For battery life the Desire is one, if not the best out there at the moment.
thank christ for that, i presume it improves after a couple of charges. mine was new on friday and the battery's pretty uninspiring so far...

My Desire has been up for 21.5 hours and has 3 bars left (according to the settings battery meter) but I've been driving around most of the day with spotify on listening to music, quite a bit of surfing, emailing, calls and a few texts.
I reckon it's probably got another 5+ hours to go yet.
My phone is quite new and battery life is starting to improve daily now.
Hmm... struggle to get more than 5 or 6 hours out if mine under relatively light usage, maybe 20 mins calls and 3 or 4 texts, if I use browser it flatten quicker still, the battery use status usually says Android OS itself has used most battery.
Hoping it will improve, at moment it is poor compared to my TD2 with a smaller battery
P.
had mine about 6 days and my battery is ver poor at the moment. however i remember thinking that about the G1 at first and it got better.
still was luck to get a full day from it. however i went to europe the other week (from uk) so turned all roaming data and syncing off and it lasted 4 days.
fingures crossed battery life increases on the desire, gor a car charger on orded fron fleabay so i should survive
i loved my G1, and found it hard to upgrade, first time thats ever happend, but wow this desire is differnt class, my wife has the iphone and is green and my 16 year old son is gutted he got the hero only 6 months ago.
Re: desire battery life
I've been running my desire for nearly two weeks now.
As usual WiFi & gps are the main culprits.
On average, I have exchange & GMAIL push on 3G all day with a bit of Facebook, sms & several min long calls without going past the three quarter mark by 5:30pm . However as soon as I switch on WiFi at home for browsing, reading news feeds, market etc, bang goes my battery!
Turn off 3G and sync and use it as a phone.......great battery life!

Yea not sure how you guys get good battery out of it. I have everything off, dark background, no synching due to having mobile network off (only thing setup to sync is email every 2 hours). I take a few phone calls maybe 30-40mins, do about 15 mins of surfing, 30 mins of music through headphones at low volume, and a game for 30 mins. That pretty much concludes my battery life for the day (is usually at around 20% left by the time I get home).
I find if I browse the market and download/install apps, my battery will go down very quickly.
Got my desire for a week now and it lasts me 2 days woth some movies, wifi and messaging. if i go even lighter, only messaging and calls it lasted me almost 4 days. it has great battery in my opinion, better than my old hd2 and even better then my old old diamond
Over in General we found an issue with the calendar app keeping the phone from going into sleep mode - That could be a cause for poor battery life.
The thread is here (remove spaces please):

My Desire have no problem on battery so far tho, 1½ day with normal use is no problem. litle use i can use it around 2 days, but with alot off things running i would say for sure it works over a full working day.
Mine has been running for 20 hours now, I have mainly been calling, texting, surfing the net (mainly facebook), and playing a game a couple of times.
I'm not really sure whether this is good or not, I would rather it lasted longer than this, as it is due for a charge within the next few hours, and this is a bit of an awkward time to need to charge it. If I wasn't off work today I'd have a dead phone before I got home.
I don't like to charge mine before it tells me too, I like to think it'll improve the battery life over time? Is this right?
those batteries are not affected by memory effect. charging everytime you can is better than drain battery to 0%
HTC have said there is a software issue with battery levels hench the charging issues. Fix in the future they suggested.
Weather this effects the actual life of battery not sure.
I have just come from the HD2
At the beginning, everyone agreed that the battery life was god awful, and a month or so in everyone reported that the battery life was outstanding!
I can confirm this, to start with it wouldnt last me a day, by the end of it i could leave 3g and wifi on all day with everything running in the background and get a good 2 full days out of it!
I just received the desire yesterday, i gave it a full overnight charge and i must report that for the first charge the battery life looks very promising
I have used the phone VERY heavily even for me with about 100 texts, an hour talking, an hour on the internet and syncing every 15 mins or so and i have 2 bars of battery left, and i said, the battery is only going to get better!
You should look at power management tips for the HD2 as most of them apply, for example disabling 'automatic backlght' and setting it yourself because that alone can add about 30% to your battery life.
currently at 2 days 15 hours with 6/10 battery bars left.
i have gps/wifi/internet disabled and turn them on with the settings widgets when i want to use them. screen brightness at about 20%
the battery is great IMO
Guys could u please tell if I should when receiving my phone charge it directly (full charge) or it's better to empty it completely and then charge it ?
Thanx
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)
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?
How's the battery life on this phone? I'm thinking about getting it.
Battery life is *ok*.... But for me, i can unplug my phone at 7am i the morning, and by 10pm when i go to bed, im typically around 15%-30%.
To do it, i use a task killer (i prefer the one by rhythm software). I keep things closed that dont need to be running. Also, i dont use the stock launcher, i believe that launcher is part of the problem since once i switched from it my battery life increased quite a bit! I use Launcher Pro.
Turn off your location settings (wireless networks and gps). Keep your screen timeout low, like 1 minute, and get yourself into the habit of pressing the power button to shut off your screen when your done.. Prevents butt-calls and saves battery!
A lot of people say the battery sucks, and keeping everything stock-ish, yes it sucks.. But when you customize the phone to your own feel with a few small tweaks, its better than most phones!

Very hard to say! But i send around 5000 text messages a month, probably spend at least an hour a day on the internet, checking emails, etc... Maybe another hour doing other random stuff? Lots of text messages and a couple hours with other stuff.. So not a TON, but not a little either.
at the beginning you will hate it !
a couple of recharges and drains till the phone shuts down
ofcourse root and remove all the bloatware and do battery calibration, and now... its the best battery on a smartphone i have ever owned !
lasts much longer than my second phone iphone 4S and xperia S
definitely much better than the S2
Battery's Great Now!
I've rooted, switched to Go Launcher, and running Juice Defender balanced profile. With moderate, surfing, messaging, email, and occasional tethering, I'm getting 2+ days. Manage to get a nice LTE signal from home. Dang! It's faster than my AT&T U-verse.
2+ days sounds very impressive. I must say its true the battery life gets better after some time, but for me its now about 18+ hours with not so much use. I guess it also depends what kind and how much apps you've installed and if they run in background-mode.
I've made the weird experience that sometimes for maybe 1-2 hours the battery status remains on one level, but later it drains a lot in very short time (usage is same like before). So unfortunatly not really reliable.

Forgot to mention what this guy said! Remove the bloatware! Tuns of that crap stays running in the background whether you like it or not! So if you use Titanium Backup after rooting, you will definitely have one of the best batteries on the market! I woke up and unplugged my phone at 5:30am, here it is 19 hours later and my battery is at 31%
I know there are threads regarding battery life out there, but most are all about usage and screen on time. My Note seems to be on par or at least close as far as screen on time. However, I'm just curious as to what all of you are experiencing as far as standby time. I've gone through the battery life guide and turned off most features I don't use, but the standby time still seems pretty lame. From a full charge, its been 3d 5h on battery with zero screen on time other than checking the battery stats right now, and it's down to 9%. Android OS consumed 57% and Google Play Services 33%.
I know I'm comparing Apple and Oranges here, but my 4th gen iPad I have for work hardly drains at all without use. After a week of standby, the iPad will only drop about 5-10%. I feel like this tablet should be capable of the same, and possibly will be after I root and find a good rom (also don't like to see any Apple product out-perform any android based product). Am I alone here?
Basic setup: Stock Rom (not rooted), Nova Launcher (prime), GPS off, Bluetooth off, reading mode off, multi-window off, screen mirroring off, s pen detection off, all samsung crap off (air view, etc), and others. Basically the only thing on is wifi.
I only have wifi off during standby and it drops 1-2% every 12 hours
You might have a tough time getting people to compare their standby time with yours... most people on this forum either use their tablet for work and if not are too in love with their baby to let it sit there untouched for days on end When I couldn't use mine for 12 hours, it dropped about 3% with WiFi and GPS on
Sent from my SM-P605 using Tapatalk
Yeah it is too hard to not touch it for days on end to test this. Turning off wifi while in sleep mode will help a lot. Go to the Connections tab in settings and hit the hardware menu key, then choose Advanced, and change Keep wifi on during sleep to never. That has helped me a ton. Right now mine is at 2d 7h 40m uptime with 4h screen time and it's at 32%. Even with that setting on, my iPad mini still gets better battery life. I have left it sitting for 2 days before without touching it and found it sitting at 92% battery life with wifi always on. My guess is it's something to do with the OS and iOS is just more efficient. That's why even with weaker hardware it can still outperform android tablets.
Also I'm still running a lot of the things you have turned off. You might want to also try Greenify. It has a non root working mode now, but works best in root. You can also try Wakelock Detector to see what apps are waking your cpu, so you can see what to Greenify. If you root you can also try an app to freeze apps as well like Titanium Backup and Rom Toolbox.
yeah, forgot about greenify. you have to be rooted though an need either the donation version to greenify play services(that's the battery killer) or use titanium to make it a user app to greenify with the free version. it's sad that google is the worst culprit with battery drain on all my devices.
I get 1-2% battery drop every 24hrs of standby. WiFi must be off, it not hard to just pull notification bar down and touch the wifi section off whenever you think you wont use the tablet for a while - takes like 2 seconds.

I have yet to try my battery life with wifi off, so I think that'll be next. I really don't need it connected while the screen is off, so I'll change that setting first.
I figured it might be difficult to get a good response for this question because I too have a hard time putting the thing down. Was just traveling for work and had it in my bag those 3 and noticed the battery drop. I appreciate all the suggestions and welcome any future ones. In the mean time, I'll be experimenting as well and report back if I find anything causing the drop.
