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

[Q] Battery life - is this normal?

Hi all,
Posted this in another thread, but I'd like to garner some more opinions.
Brand new Galaxy Nexus, 2 full charge cycles.
7h 2m 3s on battery.
1h 15m 30s screen time on.
Battery now at 49%.
Top culprits - screen 48%, Android OS 22%, phone idle 7%.
This is a lot worse than I expected. Am I over-reacting? And how does this match up to other's experiences?

Brand new Nexus S?
Wrong forum?

Sorry, I wrote the wrong phone name stupidly. I do, of course, have a brand new Galaxy Nexus

It's hard to say really, battery life depends on a lot of things - use, how much time spent on 2G / 3G / Wi-Fi, what accounts you have syncing, sync frequency, etc.
I would also say it would take at least a week of "normal" use and charging before the battery settles in, and you start to get a real sense of how it performs.
FWIW, I am pretty happy with the battery so far. It gets me through a day, which is more than what could be said about my Desire

Would you say the battery life is actually better than the Desire? I'm running CM7.1 on mine and that can easily get through a day

Battery depends so much on the use case ..
A friends charges his Nexus S every 2-3 days and I always thought "how he's doing it?"
I usually got about 18 hours with my phones so far and I would be quite happy when I get 12-14h with the new Galaxy Nexus and it's bigger display.
I think we've to get used to multiple chargers, portable charger or a 2nd battery until we'll see new battery technologies in a few years.

"There will be no specific updates coming for the HTC One X to improve battery"

"There will be no specific updates coming for the HTC One X to improve battery"
...say HTC.
It can all be found here at techradar.phones
Well what do you guys think? Are you satisfied by the battery considering the HOX's demanding setup? Mine lasts around ten hours with moderate to heavy use. Which is similar to my last phone, the SGS i9000. I found this quite acceptable.
HTC are a very reputable company, and often listen to their consumers (hence HTCdev). Is this latest move a shy away from that?
Would be great to hear everyones thoughts.

then...time to wait for mugen

I'm not having an high end smartphone to constantly be in battery problems.
I consider the battery usage as a real annoying problem with no option to buy extra batteries.
Who buys a smartphone to use as less as possible???
Sent from my HTC One X

Happy here with battery life of One X, battery is even better than it was in SGS2. For me at least. Around ~36h battery time while SGS2 ~30 hours when I was using it.

Gawwd why do people expect something with the resolution of a tv, and the same amount of cores of a high end pc, to not take much battery? I think its a bloody miracle these smartphones last longer than 5 minutes! As I've said before, you wouldn't expect a supercar to be economical?
Plus, the battery is an improvement to my dhd , so that is another miracle, considering the extra horsepower behind the one x

Where's the like button? I really do wonder what people expect. Get a Motorola if you want the battery to last you for a week.

More than happy with the battery life of the handset. Lasts me from when I leave home in the morning till when I get home at night and then some. Beats having to charge my phone during the day like on my DHD.
People need to get used to charging their phone every night, really don't understand people's issues with that. What's the big deal?
Sent from my HTC One X using XDA

I know!!! My DHD is on the charger every night! It doesn't bother me

Why would they? It's fine.
To all the "glass half empty" whining types. You guys do know these things charge from USBs right. I got a great solution; plug it in when its running low.
Besides, the battery life is staggeringly good if you think about it. Mine lasts 2 days for simple calling and texting here and there and a whole day for quite heavy usage, browsing, YouTube, calls and so on. 18hours total, 4-4.5 hours screen on, 40/50mb data and 1.5 hours of calls yesterday, put it away at 1%, still not dead 2 hours of standby later.

Mine's OK, not great. I really didn't expect it to be. It'll be interesting to see how the S4 One XL does now that it's shipping. If it's about the same (with LTE off) than it's not a Teg3 issue. If it's dramatically better than we know it's not the display alone causing battery challenges.

I think that no update coming anytime soon is acceptable but no update AT ALL?
Im sorry but f*** that! Why can't they focus abit on the battery, some simple things would be to have less CRAP and bloatware, maybe if they could release 2 versions 1. simplified with the sense camera ONLY and rest ICS and the other with the full sense package that is really no necessary.
The most important thing to remember is that this a a PHONE to make calls and for that it works nicely and the battery lasts if you keep the screen off most of the time, but for a phone like this that was made to do more things I think you need to at the very least have a battery or a software symbiosis that can last for 8,9 hours of screen time.
Its Tegra 3 for f*** sake! With the super-dupe-triple-super-important-kill core2dou like nothing-quad-core-and a dedicated 5 companion core THAT IS SUPPOSE TO DELIVER KILLER BATTERY LIFE.
What is the problem?
I think there is simply too much Sense on the phone, too many uneceassy widgets and other crap that run in the background (oh you can flash cusom rom bla bla, you can freeze services with Titanium backup bla bla, but what if I want to use a stock rom?) bull**** I say, wih such and advanced CPU and memory and so on I do not see why you cannot have better battery life.
My Samsung Galaxy S2 can work for up to 3 days (ok it has a AMOLED ok ok but still, touchwhiz seems to not over run ICS) On stock ICS. Why? Because they have less 'painted over ICS functions that almost makes it run 2 OS's at the same time so maybe its no wonder the battery gets chewed up by all the sense applications.
This just my opinion from observing the phone and all the fanzy sense stuff after a week.
I believe this phone could be better in terms of software (without a doubt).
One thing they have to adress is the camera, why cant the image files be bigger than 2.9 megapixels? This is so stupid considering it has an 8 mpx camera... Also the full HD and 720p records in the latest firmware 1.28xx at approximately 24 fps and it should be 29 or 30. My Asus Prime records at a steady 30 fps at 1080p and 720p and its running Tegra 3 too.
They MUST at some point focus on battery life because if you dont have the juice to run all those fanzy apps and UI then why are they there in the first place?
I LOVE the weather graphics but I could live without it too (If I absolutely HAVE to....) the only thing necessary is the camera sense app because its the only thing that makes the phone unique and very fun and nice (but again whats the point without proper battery life?)
I hope HTC continues to work on making this one of the best first quad-core phone.
Another thing I noticed with SetCpu is that the phone is very high frequencies very frequently, if you install it and use the phone for a day you will see the graph scale, it uses 1.4 abut 40% of the time, but why? I never played games during this period or anything.
Im gonna keep my 1X because I love it and I believe in it and in the HTCdevs if they cant just be more positive perhaps
Cheers!

4-4.5 hrs screen on isn't typical usage that the majority are getting though. Closer to 3 hrs.
It's easier to be quick to judge others when your own device defies the norm for the better.
If you were struggling to get 2.5 hrs , I doubt you'd be as chirpy about it all.

Two words that will help battery life without HTC - "custom kernels"
If you need to see the difference they make just ask in one of faux's threads, e.g. in the Sensation dev forum.

did the update improve the batterie life and if so , does the HOX still run as fast or did things low down ?

Pretty much echo the below , i have had an sgs2 and have an xperia s and this phone with its companion core is at least 33% worse on battery than both of these, and the processor is supposed to be more efficient . The display excuse won't wash much as the xperia s display is at least as bright/power hungry if not more .
I would love to see the exchange / return rates on this handset due to it not living up to its hype , let alone the fault rates.
And i am not whining, i upgraded to one, i like it , i will keep it and maybe one day learn to root it and replace the rom, but lets not kid ourselves its just not a finished polished product in terms of software !
thats my 2p, thanks for reading

[Q] HTC One X - Battery Consumption (How long does it last?)

Hi there,
I am a proud owner of HTC One X ..
TO me, this smartphone is awesome, its fast and i love the design.
I'm ok with the heat, at times it is HOT, but due to its Quad Core processor, well, i can live with that...
BUT battery wise... How long can yours last ?
I'm pretty new at Android and this phone makes me busy because i am trying to keep up with the Android world... And boy... i'm glad to leave my IPHONE in my drawer... No more IOS !!
Is there any fix to the Battery issue?
If there is, have you guys tested how long more can it last ?
I can use for 2-3 hours and i'm left with 45% battery !!
Anyone ?
Please reply.. i would luv to hear from you guys...
I really luv this phone but the battery is killing me..

The problem with the one X:
leaving it unused (full connectivity 3g,wifi,sync) draws about 0.6% per hour.
But once you turn on your screen and start browsing the screen will deplete the battery really fast. (As will gaming)
Once you get used to your phone and you don't use it hours at a time anymore you can easily get 30+ hours of usage time which is way longer that any smartphone I had before this one (G1, legend, Omnia7). At this moment I have 23 hours of battery time with 36% remaining.

Yeah the screen is a massive power user.
I didn't really use my one x much the past few days and it lasted 51.5 hours! That's with wifi on, data on, cellular radio on etc. Only 1 and a half hours of screen time though.
I'm still very impressed, much better than my iPhone 4S could ever have done
Decided to plug it in now as it's down to 3%
Can't post links to the screen shots unfortunately
Tom.

Thee is a huge thread on battery life already here:
http://forum.xda-developers.com/showthread.php?p=25095183#post25095183
Try to read abit before starting a new thread.

I don't think I would be half as annoyed with the One X if it just charged faster. Almost 3 hours to recharge a battery is kind of ridiculous.
Hopefully someone will make a custom kernel with a fast USB charge patch.

[Q] Best battery charging practices?

Hello all,
I hope I'm not beating a dead horse by asking this because I have searched this site as well as other places around the internet and there seems to be alot of information out there concerning how to charge your phone battery. But every time I read something, it seems to contradict the last thing I read. So I wanted to pose both viewpoints to the experts here in one place and hopefully get some clarification.
I recently got the Note 2 and am really happy with the phone. One of the biggest and most welcome surprises is the terrific battery life I have gotten so far. I am coming from a HTC Sensation and while I liked that phone, I always felt like the battery life pretty much sucked. When I first got the phone, it would barley get me through the waking hours of the day and that was only if I used it sparingly. Over the course of the nearly two years I had it, the battery life just got worse. I typically would leave my phone charging all night as well as in the car during the day if I had heavier use that day.
With the Note 2, I am seeing much better performance. I can easily make it through a whole day starting at 6am and by the time night comes still have over 50% charge remaining. I am not a heavy user but I have found myself using it more, trying to deplete the battery so I can charge it at night. My problem now is I can make it through one day with no problem but to make it through two full days may not work as well. I feel if I don't charge at night when its still around 50-45%, the next day I may need to charge right in the middle of the day when I need to use it or am not by a charger.
So my question is what is the best practice? Is it best to fully charge then fully discharge, and if so does it need to be a regular habit or just the first few cycles? Do I need to remove the phone from the charger once its fully charged or will an overnight charge be a safe option? If the phone is only at 40% or more is it ok to charge it? Are there any other battery management practices I should be aware of?
Thanks in advance for your help

dont read too much into battery charges...charge as you like...........at home, in car, connected to pc...........lol..........the battery will last for 2-3 yrs well...then if you feel it is dying, it has a removable battery.........you can always change the battery, buy a new one...they are cheap...
for ex:
you get ~1200 cycles if you charge from 40%-90%, but you will charge twice a day (2 charges a day will last ~400 days)
you get ~400 cycles if you charge from 10%-100%..charging 1 time a day will last ~400 days again

The above is the only proven effect on our batteries. The rest is handled by the battery itself.

Honestly ive always charged my phones however and whenever I liked. Overnight and at varying parcentages. Never noticed any battery degradation at all. My x10 battery seemed the same as the day I got it after 2 years.
I figure any detrimental effects will probably occur after 2 years of bad practice at which point most people would have a new phone anyway
