Desire battery life

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.

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

Serious battery drain :(

I got my Desire in april and ever since I've never managed to get the battery to last more than a day.
I've tried different ROMs (Defrost, OpenDesire with and without Sense, MoDaCo r4, DJDroid, Neophyte, Pays-rom 2.1) but it's always the same: almost no drain in sleep mode but as soon as I turn the screen on and start using it the battery goes down ~20% every hour. I don't believe that's normal since some people get 3-4 days out of their battery.
For example, today my phone has been on for 2½ hours and lost 43% battery with WiFi on, just surfing the net and using Tapatalk.
The screen brightness is fixed at 30%, auto-sync off, bluetooth off, network mode set to WCDMA only and I have good 3G reception where I live.
I have no clue what to do, maybe someone else does?

I have the same life spend for my battery. I think its quite normal for desire. Unless I'm abnormal too : x

You can use setCPU to underclock the processor or to create rules to make it powersaver.
I (as many other people) have one for setting the max/min processor to 245MHz when the screen is off, so it doesnt waste so much battery. I havent tested a lot, since I did it yesterday but the battery is lasting longer.
Also there are different ROMs that have better battery life...

I use JuiceDefender. Just by installing the free app from the market, I've increased my battery by 1.5x what it was originally.
With Ultimate Juice installed, I saw an increase of up to 2.5x.
Sods law, I can't purchase anything via the market due to having a Google Apps email account :|

I've tried it but it's not helping since I'm not syncing anything automatically anyway and the battery isn't drained with screen off.
It's when I start using the phone my battery percentage goes bananas.
And btw I know how you feel, I live in Sweden and we don't have paid apps here. Thank god for MarketAccess.

My Desire was acting like that during my first 2 days of usage. The battery was draining really fast even in standby mode. I installed advanced task killers and after that the battery improved. I do not know if it is because this app or there were some other configurations that I accidentally did...
But the battery life right now is way better than before (even lasts longer than my previous iphone 3gs). Hope this helps =D

I have pretty decent battery life and I use the stock unrooted unmodified rom. Some apps completely obliterate battery life. I used to keep eBuddy open, but I found that it kills my battery faster then anything else.

Hmm, when you say "just surfing the net", you're actually using WiFI + AMOLED + CPU, which are 3 of the biggest battery drains on the device.
IME, you can get days out of the phone, but if you actually have the screen turned on all of the time (i.e. you're actually using the phone), then 20% per hour probably isn't that insane. After all, that's 5 hours of continuous use, which isn't too awful from a modern smart phone.
Honestly, I think the answer might be "Yes, it does that" and "you'll probably need to charge it during the day". I've taken to charging mine on the way to work and back again (about 45 mins each way) and I'm still at 90% at bedtime.
Oh, and forget JuiceDefender. Yes, it makes a difference...but only when the screen is turned off. As soon as you start using it (and that's what you're obviously doing here), it shifts out of the way. Once I realised this, I uninstalled it...never looked back.

Oh, couple of other notes. Bluetooth doesn't make that much difference unless you're actually using it. 3G uses quite a bit more power compared to 2G. Consider switching to 2G when you're on WiFi. (sadly, no automated way to do this )

i am not using any of these tools.
i have wifi always on 3g on
no live wallpaper and push mail (k-9) with 2 accounts
my battery lasts 1,5-2 days. with phone turned off during the night. 0am till 7am.
i am surfing a lot and writing a lot emails.

Here comes a hint:
Turn off ALL unnecessary widgets like "Bluetooth", "GPS", "WiFi". Turn off also "Mobile"-internet widget, and turn it on only when u want to update some apps or check your mail.
I have noticet that "Mobile"-internet widget drains hell of a lot battery, but if u turn it off now and then u will have ure phone, like I had, for 6 days - with one charge!

[Hint] Battery Usage (2 days 30%)

I've always been impressed by the battery life on Defy ever since I owned it. I haven't owned other smartphones before to be able to make a true comparison but using electronic devices for a long time I can tell the battery usage on Defy can be impressive. However, there were times I noticed the battery was drained so quickly.
In my latest watchful examination of battery usage I have achived to use only 30% of the battery for more than two days. Here is a summary of my usage in the past two days;
4 Hours Music Playback (PowerAmp)
30 Mins wireless
About 16 hours airplane mode
No phone calls on my mobile but I did dial a number several times
I have fully charged the mobile on Friday morning and on Sunday morning the battery has 70% charge.
Hint:
As it was stated in user manual it is recommended to charge the phone from mains socket whenever is possible. I can confirm that I've seen battery improvement after recharging the battery by mains socket after several times.
Since I don't have a use for MMS I have renamed the APN server. The same trick can be used to disable data and that saves battery life too if you don't use your phone to push/pull data.
In the past 2 days my network type has been set to 2G only. The automatic setting certainly have dramatic affects on battery.
Before going to bed I put the phone to airplane mode since the reception in my bedroom is very weak and this increases the battery usage.
With simple measures the battery life can be extended (noticeable) more than what you'd expect.
I'm very pleased with the battery usage so far. Nonetheless, I will buy a spare battery as soon as it is available in the UK.
Happy New Year XDA

Yours are the most impressive stats for the battery use. I've set my Defy into saver mode, and the network data to 2G as well (I only use it to sync up with Gmail (plus Calendar and Tasks) and my employer's Exchange email) and get down to 50% after two days of moderate use, which is enough for me not to worry about running out of juice if I'm away from home for a few days. Yes, the Defy can be pretty frugal with battery use.

I ended up having my original Defy swapped because of concerns that the battery wasn't up to scratch and the new one's been brilliant.
I'm in 3G all the time, never put it in airplane mode, and after 62 hours I still have 20% left - that's with me having used it for some calls, texts, web browsing, facebook and a good couple of hours of Angry Birds as well.
Definitely the best smartphone around for battery life IMO.

What does mains socket mean? The wall outlet (I am in the US).
If so, how else would you charge? Computer USB?

If its the bit in the wall that the electricity comes from then its the same thing :L and yeah you can charge it from a computer USB but it takes a little bit longer

Yeah, seriously.
I'm not talking about hours of calls, more like 15 minutes or so. Maybe an hour or two total web browsing and facebook and perhaps an hour on Angry Birds.
Part of the reason it lasted so long was that I just didn't touch the phone on Christmas day at all, so that was 24 hours with basically zero use, which is unusual.
The next charge last more like 2 days, which I think is closer to how I'll be using it normally.

if you put it in air plane mode, and a couple hours later u turn air plane mode off. will u get all of your notifications? like calls,texts and stuff that people sent to u while the phone was in airplane mode

There is true gem on the Market named JuiceDeffender Beta - I used it since my Milestone and it really does what it says it does. All the hints you mentioned already included in the program and are being controlled by it. For example, as soon as you display turns off your network automatically switches to 2G. In paid version you can even adjust processor's speed when needed (underlocking of course, in terms of battery saving) However i am currently on free version and it's enough to make the battery last almost twice as longer.
I had some problems installing it on Defy, but they were all gone as soon as I rooted the phone.

How did you get the 3G -> 2G to work? I can not enable that feature, as I am not using a CyanogenMod rom and I can not download/install AOSP helper as it suggests. I am using the beta and UltimateJuice, which I purchased after seeing what features it provided. I'm using the CPU features to do what SetCPU did for me - no need to have two packages with overlapping features installed.
*update*
From the author of JuiceDefender:
In practice the only ROMs known to work are CyanogenMod (any version) and the Nexus One stock ROM..

[DISCUSSION] Xperia S battery life

Had my beautiful white S for 24 hours now. Overall very positive, except battery life so far. Drained 23 % overnight from a 100% charge. In only 7 hours I had NO activity. BT and WiFi on.
I hope this will improve very soon. That is a no go. Would like to hear from you about your experience regarding your new Xperia S.
Sent from my LT26i using XDA

For me, I removed junk I don't use, like foursquare. That alone made a huge difference. I also turn off data at night, and only went down about 4% while I slept.
Another option is to install something like JuiceDefender, which automatically shuts down data except switching it on every hour or so to allow for some syncs, then shuts it down again.

same as my arc, drained about 30% in the first day, with time it'll be better.

i was about to ask the same question. 7 hours seems about right, but i have been doing a lot of app installs, so I will give it time to settle down.

I use the XS in Hong Kong. If I use the phone online to play with internet browser, battery will be drained from 100% to 69% in approx. 1 hour. Is it too fast? Or it just a normal way when compare with SII or GN?

Ohh yes. U are soo right. Had my phone now for 4 days. The display uses an average of 70% of the overall battery consumption. It is not WiFi, calls, BT or any other functions. It is the display that drains. Will give it the weekend to see if it improves. If not I will return it on Monday :-( And my brightness is down on less than 25% so not much to do there.

I get about the same on my Arc. I dont know if it's too fast or not, but if your pretty much constant on the net for an hour say then 69% isn't all that bad.

Had an Arc for around one year. On a daily average the screen took about 55% and I had no problems to get a full day out of it. (approx 16 to 18 hours) and still 10-15% juice left. Now I get max 10-12 hours out of my S and NO juice left. Really disappointing. Even my old X10 did better than my new S.

Surely the HD display amongst other things, ie how you have your phone set up, may go someway to why your experiencing poor battery life compared to your Arc.

Try to disable Bravia engine and see if you notice any difference especially during the night.

My phone has the same apps as my Arc, actually minus few of them.
No autosync etc.
Basically it drains the battery quick, it's unacceptable. It behaves exactly like one of the older Arc firmwares, which was also draining battery like crazy.
Than they fixed it and it's still brilliant. My Arc on Flight Mode beeing just a backup in case of any problems, runs 3rd day on one charge, still 75% left.
I think S is just not optimized and it makes me mad.

Just got My XS yesterday I did one fully charge this morning . Turned off data at home, will not know until battery is fully charged by a few cycles. I love the phone irrespective of the flaws. I think may be see in a week or 2 where my battery settles.

Again. 25% battery drain in only 6 hours over night. No physical activity at all. This baby goes back on Monday :-(

3g turn on with weather widget in background only, 4% drain overnight, but with heavy usage (game, internet suffering...) it lasts about 7 hours, that's good.

You can use Profile Scheduler (free from market) and set a schedule.
I've set the schedule in which the airplane mode will be activated at 12.00 am and turned back to normal at 6.00 am.
By this way, my phone battery drains overnight just only 2-4%.
Let's try man

I actually agree with that tbh, and another thing is battery life all depends on how the individual uses their phone.
I had the sgs2 and alot of people said oh the battery life is rubbish but yet they had:
screen brightness on 100%
3g, wi-fi, bluetooth always on
live wallpapers running.
Plus they were using the internet for like 2hours
sending numerous emails
playing games
listening to music
I mean come on its a phone at the end of the day, its not a super computer or something or some nuclear powered device.
I nearly 2 days out of my sgs2 under moderate - quite heavy usage
because I turned my screen brightness all the way down
didnt leave 3g, wi-fi, bluetooth on all the time only when i needed to use those features, i never used live wallpapers and i dont send numerous emails.
when i had the play again people said the battery life was rubbish but again i got about 1day 10hours or a bit more sometimes based on the above mentioned info.
so as long as my SXS last 1day even I dont mind that because at the end of the day it has a HD screen so its going to use alot of power.

Okay so on my third day with the phone...
my battery is fine, actually...more than fine. I turn off my wi-fi/bluetooth/gps when not needed, and I don't run my battery heavy apps for a long time.
I also installed a task killer...I know it's in theory not needed, but I will see how it goes.
woke up around 7 today, used my wifi, used a battery intensive app (dream zoo , it's an addiction) for like 15min or so. Went for a walk, used the camera...a LOT, made a lot of panorama pictures. It's now almost 11:15 and i'm only down less than 15% I believe.
It's got much better battery usage than my X10 to be honest...but this is a high-end full HD phone, I wasn't expecting my battery to last so well D:
I will update again at the end of the day about how low it got, but I am pleased with it.

Battery Life

What kind of battery life are you guys getting?
On good days, this is what I am able to get.

Bad batterytime!

I dont get it.. I got the phone 3 days ago, but if Im lucky, the phone lasts for maybe 6-7 hours?
It gets extremely hot when used in couple of minutes, and its like the battery is drained by something hidden.
On a night it loses about 6-7% in 6-8 hours of standby with data etc turned off
I have turned push, sync, NFC, smart screen and all that "smart" stuff off.. so I have no idea bout what drains the battery. Even the screen is on 50% and auto -_-
I have the korean version (I think?) the european version - bought in Denmaek, stock. Not rooted or anything - but is it possible to root the EU/KR edition or is it only for the Canada/Sprint edition?

Same for me. Hes obviously not using hes phone much and not on LTE.
The battery life of G on LTE is really terrible.
By the way mo on arent hot last days, probably they fixed it.
Web via LTE eats like 15%-20% per hour, reading a book on small bright is 3%-4% per hour

Is there any way to tunr of LTE/4G then? I'd rather have good battery and like 20mbit than a few hours battery and 45-50mbit download speed .. :laugh:

Battery life is consistently around 11.5-13 hrs with moderate to heavy usage.

My battery is crap too sometimes is ok ..
but it is just screen what drains .. and + if u browsing internet and u have flash enabled it is big drainer added .. needs more cpu power..
if u put mobile on eco mode turn down screen to 25%-30% turn all radios off u should be fine
download apps like battery calibration . or battery stats or juice defender

I'm really not an expert at this. I have also just opened my Optimus G, so I can't share my personal experience with this phone. However, the battery of my Lumia 920 needed around a week to function properly. The first three days I got heating and drain, almost 10% per hour, but now the phone lasts easily for two days with light usage. I was looking everywhere on different forums for hidden factors draining the battery, until I found a comment, where someone described this phenomenon: he said that a battery needs around 12 full cycles of drain and full recharge before optimal performance can be obtained. So from now on I will be more patient.
Then again, I'm new here, so other opinions are welcome.

eeemm that is not true i had phones over years and batt been always same..
it is all about usage ..
jut do test charge it fully and dont do nothing with it just ocasional phone calls and sms's and ull see then..

For me on jb v03 I get around 18-19 hours with around 3 hours screen time, but agree its all about usage.
I mean if you leave your phone off most of the day with your wifi and data turned off it will drain very slowly..
I find the biggest drain is always screen, cellular connection especially when you have poor signal, and wakelocks.

I had same xperience with my iPhone 5 so I hope its the same with my LG.
But for know I've installed JuiceDefender and disabled LTE (HSDAP+ i fast enough for my needs on the phone anyway)

exactly this is my problem ..
we traveling to the places while am in work and there are areas where is poor signal or no signal that means phone automaticaly boost its signal which is very big drain and if your mobile has no signal at all and u obviously set to automatic search it searching searching and draining hell lot!

this is true as well 4g signal is even stronger signal as previous 2g 3g drains so much plus when u surfing on the net!
when 4g will be standard the manufs will have to make new generation of batteries to stay last longer o LTE..

Phone idle is draining battery for me. Any suggestions?

I've already installed most of "LG" apps that were preinstalled on the phone.
Phone idle 28%
Screen 17%
Cell standby 17%

Phone idle refers to the amount of battery cell radios are using up when the phone is sleeping. I would recommend moving to an area with better reception and disabling data when unneeded.

Data is disabled (and wifi).

battery life is fantastic, i get roughly 5 hours on screen time, when i finish work i have 70 - 80% battery with 1.5 hours screen time

My battery life on CM.
Disappointed kinda, expected great improvement compared to stock rom

After few weeks of heavy usage, I am noticing the battery performance to improve considerably, I'm running stock 4.1.2. V10D
