[Q] Desire HD battery life question before I buy

Hi,
I'm planning on buying a Desire HD, but just curious about battery life before I lay down a grand on it.
At the moment I have an HTC Hero, when they were in their heyday many people complained about the short life on them. I can get 2 days out of mine, with syncing over wifi enabled the whole time. I put the complaints down to people with background apps sucking CPU or too much twitter/facebook/whatever crap syncing as well.
Now most of the reports of poor Desire HD battery I life are from people on their first charge (who clearly don't understand the characteristics of Li-ion batteries), people who expect to be able to thrash the phone all day with the screen on without it dying and generally people who just don't sound like they know what they're talking about.
I know there are two bugs which peg the CPU at 100%, the one fixed by having debugging on and the calendar bug, which sounds like it can be fixed by clearing calendar data or leaving syncing off. I think these were affecting some of the people who were complaining about the short battery life.
So my question for Desire HD owners is, can you last at least 6 am till 10 pm with a bit of use (something like 10 min browsing, 20 min IM, email syncing all day, 1 hr music, 20 min calls) without it dying? Currently my Hero does this fine and a full day without a charge is a requirement for me.
Thanks.

Yes, if you set it up correctly. From your post it sounds like you know what your doing when setting it up.

Before i tried the battery calibration i was getting from 8am to 9pm with moderate usage. TBH i was put off by using it as I thought it would just die on me too soon.
After the calibration (search forum for it) i got from 8am to 4pm the following day where the 15% warning hit. So do the calibration and you'll be as happy as i now am with it. I never got my iPhone 4 to last that long!

Thanks for the info guys, exactly what I wanted to hear!

I haven't taken any precautions to save battery life and I am getting 25-26 hours on a full charge...and now having had the phone for 2-3 weeks it seems to be getting even better!! I've been getting 36 hours out of a full charge these past 3 days.
I do not turn wifi off. I have screen brightness on auto. Syncing lots of stuff hourly (even weather!). I use 3g when I go out but this is about 2-3 hours tops on week days cause I have wifi everywhere i go. battery life has never been an issue for me and I use my phone frequently...play games for 20-30 mins. watch videos via. skynews, listen to some music etc. etc.
As for the bugs...I do not have usb debugging turned on and I have never had the /INIT problem...perhaps it was fixed in the last update? and the calender bug...never had that problem either and I use my calander with google calander, facebook, holidays and person agenda.

I think you'll easily last a day with the usage you mention. As a rule, I think you normally get up to 4 hours display on usage off a charge (browsing, messaging, watching vids etc).
I'm travelling from Ireland to NZ on Monday, which will equate to 36 hours travelling with probably no access to a charge, and lots of time spent sitting around using my dhd. There's no way the phone will last right through, so have bought a 5000mAh USB battery pack for £20.

I'm currently at 22 hours and still at 42%.

I get 2 to 4 hours depending on useage from full charge. 8 - 9 hours if left on standby and not used for anything.

Well...I think I have had similar results....
flash one of the custom roms, with one of the OCUV kernels and setting max. speed to one of the UV speeds (mine is set to 1.1 Ghz which is UV 50mV), also setup useful profiles in Setcpu (I have set screen-off to use max 384 mhz - which does cause a 1-3 sec lag when screen is on again) and <20% battery etc...
of course, if you play heavily with your dhd you will not get these results, so you can put wifi on with this , but need to think of what you want to do, because using your DHD for 2 days, does require limited screen usage (imho, this uses a lot of battery)

8-9 hours on standby???????????
even 2-4 hours whilst using it is terrible!!! When I got my HD and unpacked it I didn't put it down after a full charge and I got 8 and a half hours with non-stop heavy use.
I think you have a faulty battery!!

I too moved from a Hero to a DHD and I can say that with similar usage, the DHD loses to the Hero by a decent margin..maybe u might get a couple of hours less of usage compared to the Hero but the difference isn't very drastic
Moreover on the Hero I'm using CM6.1 Froyo overclocked and the DHD is on Sense, so logically speaking the Hero should get slightly better battery life on CM6.1 compared to Sense. I'm sure after rooting and flashing CM6.1 and undervolting/underclock the DHD, i'd get better battery life because the DHD is like much much faster than the Hero, so I'm sure even if i underclock it, it'll still be super fast.

The battery is 'fine' i'm using current widget to track and its performing to around 1100 mah which is not too far below spec. The problem is the current draw. In use i'm drawing 500 to 800 mA and in standby around 80 to 300 mA. These figures are consistent with the battery life I'm seeing and the battery working close to spec (1230mAh i think?)
There are lots of bundled apps like Maps running all the time in standby drawing current and I haven't yet figured out how to stop them. Stopping them with task manager just sees them restart with even bigger current draw.

Something is definitely wrong (as I'm sure you're aware) with only 9 hours on standby.
Out of interest, remove ALL widgets and see what difference it makes. Also, give us an example of what processes are running?
I would get rid of all task killers and also anything monitoring your system. Those themselves can draw more than you think.

wow well I'm no battery expert but it really sounds like something is not right there. I don't have any battery drain from apps in standby and I do use maps.
I got 1 day and 16 hours from a full charge today (just put it back on charge now).
Thats with wifi on for 31 hours (always on, doesnt sleep when the screen locks), 1 hour and 24 mins of talk time and the screen on for 4 hours and 5 mins.

thats definitely wrong somehow.. should never drain that much, perhaps it is because you let currentwidget drain it all the time
(na dont know why it is like that but it definitely is way too high)

official firmware, medium screen brightness, default sync widgets
heavy use: 12-15 hours
light use: 24 to 36 hours
this is how its been for me ever since the battery calibrated, needs around a week or use the battery calibration trick

I too have just moved from a Hero (running VillainRom 12) to the DHD (stock Sense over FroYo) and even though I have only had it a week, the battery easily lasts a whole day with the moderate use you describe. Unless I get stuck into a session of " Angry Birds ", which seems to kill the battery pretty fast. But ABs had the same affect on my Hero. Constant screen time on that beautiful 4.3" display sucks the battery. I find the same thing when using the DHD as an in-car gps. The warmth of the back of the case is testament to how much energy has been expended. So I connect to the car charger now. I have also bought a portable backup battery (plugs into the microUSB) just in case.
I don't regret spending NZD1000 on the DHD. My son is looking forward to inheriting the Hero.

Well I charged it up overnight when I got it, my first full day was today and I got 7 am till 8:30 pm using it almost constantly (quiet day at work). I don't know how people can run them flat a day with normal use. And I know it'll improve a lot after a few charge cycles.
It doesn't look like it's going to be much worse than my Hero.

Thanks for all the advice. I uninstalled all widgets and it improved a little. But still things like maps/maps sync were constantly burning juice and no way of stopping them running.
I installed Launcher Pro and can report that my battery life has approximately doubled. Typically i was getting 4 - 6 hrs use and sometimes only 2 (light use). Now getting between 8 and 12 hours of fairly heavy use. Its still not up to some of the figures others are reporting but Launcher Pro has helped a lot as all those constantly running apps that were draining my battery just dont start themselves up any more!

[Q] Battery consumption: I need your help for a comparison

I found a very good program for my Motorola MB525 (Defy) for monitoring the battery draining from the market.
It's name is Batery Monitor Widget and it's free.
With 81% of battery it says only 7 hours and 16 minute left without doing anthing!!! The data is on and Wi-Fi connected to my home network.
Is it normal?? In the night in airplane mode after 9 hours it drain 8%-9% of battery. Again: is it normal???
If you can try this application and report your results...I think there is some application that drain my battery!!
Thanks!

Not really a comparison here, just a little story.
Yesterday i screwed up my Defy playing around with some rom. Nothing terrible, but i had no time to re-flash another rom, i had to go to work. So, i pickep up my old SE xperia x1.
After an entire day, 4-5 calls and several sms, that phone drained less than 10%. Then, last night i put the x1 in stand-by, well, that was a real stand-by, no power consumption at all.
Now i'm back to Defy, 2 hours, 15% drained...
All this just to say android is amazing but terribly hungry of power, even when the screen is off, even when airplane mode is on. I don't need a comparison to know about it
EDIT:
you said your wifi was left on, well android is hungry of data too. Even if you do nothing while wifi is on an amount of data still flows, sometimes i can see several mb downloaded by my Defy in a few hours, but no real usage by me. This also contributes, you should try to turn the wifi off or disable background data when you don't need it.

In standby (3g, sync only calendar and contacts) I have 1-1.5% battery consumption / hour. I think this is normal
With my normal usage i have some 20-40% left at the end of the day... also Ok.
WIFI on & connected will consume a lot of battery so I am not surprised.
BTW I also had an Xperia X1 and the consumption was roughly the same as the Defy... In fact more than 1-2 days on a charge I very rarely had on any of my smartphones with normal usage.

last week I was working in the forest for a few days with no signal at all, so I turned on airplane mode: I remember it going from 45% in the morning to 42% in the late afternoon!
(with everything turned off, just used it occasionally to have an idea of what time it was)

It's ok to be an android fan, i like it too, as i said it is amazing. But, battery life is definitely NOT the strong point. I can compare the two phones now, at this moment. Honestly Defy's battery life is a lot shorter.

what's the other phone you compared?

I really don't have problem with Defy's battery life. As far as my memory serves, all cell phones I ever owned (7~8, all nokia, se, moto) could standby (just standby and don't use at all) for a week or made around 5 hours call. In my case Defy can also standby for a week or allow 5~6 hours usage.
I'm on a 2g network (probably helps alot), as I have wifi at home and at work. I have an exchange email, a gmail, 2 yahoo mails, and a weather app, all allowed to sync at default settings. I don't have facebook or twitter. GPS and bluetooth are enabled only when necessary (occasionally). I overclock Defy to 1000Mhz with SetVsel, and underclock to 300 when screen off. With conscious observation over some time, I find that 1% battery is consumed around every:
- 2 hours standby with wifi off; or
- 1 hour standby with wifi on; or
- 3~5 minutes usage (calls, emails, surfing,...)

thats some amazing battery life u got there abc ...what rom are u using?

hey guys, just a quick question. with which setting do you think i'll have longer battery life: 800MHz/58vsel or 1000MHz/56vsel? btw, i got my phone stable at 800MHz/45vsel

I was using the orange 2.2, and am using the finland 2.2 now. Both have similar battery usage.
But I have uninstalled some stock applications which I don't use but keep running in background, like BlurHome.apk (with Launcherpro), InPocketService.apk, ToggleWidgets.apk (with ExtendedControls), WeatherWidget.apk (with FancyWidget), VSuiteApp.apk etc.

You may be right, I had the Xperia X1 something like 1 year ago.
I had until now FSC T830, HTC Hermes, HTC Diamond, Xperia X1, Samsung i7500 Galaxy (my first Android), Acer Liquid and now the Defy. As far as I remember I always had to charge every night (or every 2 nights at best)
Overall I think Android battery life is worse than Windows mobile was BUT I also have more background programs running now than I had in the WM days.
What I definitely don't like in Android battery life is lack of consistency. One week you get30-40 hours at a charge and suddenly 12 hours... Than you have to make detective work: look what new App might be the guilty one, check what's running in background, reboot and see if it happens again, factory reset, etc. I guess this is the price of freedom

Im on uk 2.2 and i get three days at a push i jus have a weather widget on sync every 3 hours.
Iv also undervolted 300/16 600/29 800/39 with setvsel on performance mode and up threshold on 99% and limit to vsel 1 when screen iz off
Im on three uk so im constonly on 3g and use no wifi etc etc with normal sms usage and a few calls through out off 1 charge

There has to be something wrong in your case. I find that there seems no wifi/2g/3g connection. Could that be the problem?

I dont use 3g ..cuz its expensive in my country ..and I only turn wifi on when I need it
And that shouldnt be the case ...I think id loose a lot more battery if wi-fi would be on all the time

Ughh battery drain definitely too fast.

I feel like I make a thread for each phone I go through. First Blackberries, then Droid X, now Galaxy Nexus.
I am getting pretty horrible battery drain that is definitely worse than others' Nexuses. I have gone to the extended battery now for a few days, yet in the morning, when I unplug from charger (says 98% but charged?), with brightness only a quarter of the way up from lowest, I can literally watch the percentage (battery number mod in corner) drop one-by-one each minute or a few...So if I am actually using the phone, you can imagine it drops pretty fast. Yesterday, with very very moderate use the phone was still dead within 5-6 hours. It was at the mid-80s within an hour or more. Again, with moderate use.
It is stomach-dropping watching the percentage number just go down and down. Yet my friend's Gnex using the extended battery his first day did not hit 85% yesterday until 5+ hours later. The battery stats page on mine shows nothing with high numbers except Screen and Android OS, so I assume no apps are draining it. I am rooted with unlocked BL, on bigxie's deodexed ROM with softkeys mod, battery percentage mod, and power menu mod. I have 100-something apps and many widgets but no battery draining/updating ones. Others with the same ROM report fine battery.
I believe after using the ext. battery for a couple days, it should be "conditioned" if needed at all, yet I see no improvement.
I'm getting very angry watching this drop.. For example, 40 minutes off the charger with almost NO use except for turning the screen on here and there, I am at 94% battery with Screen at 46%, Android OS at 34%, Phone Idle 11%, Cell Standby 9%, and Android System 2%.
And then 1 hr 20 min in, at 88% battery with 55% Screen, 27% Android OS, 6% Phone Idle, 6% Cell Standby.
This doesn't sound normal right? Keep in mind, those numbers are with almost no phone use..very minimal settings menus visited and one update from Market.
Jesus, literally almost every time or two I turn the screen on just to check these numbers, I see the damn battery percentage drop a number. Not even using the phone how/as much as I normally would be. This is infuriating. Luckily, it doesn't seem to drain much with the screen off.

Quit checking and wait til the bug is fixed and blood pressure stabilizes?
Crazy world, ay?

Update to 4.0.2 or 4.0.3 with an improved kernel = success.
Use the phone for 1-2 weeks to stablize battery life - mine is better now than it was when I began using it. But the kernel/rom makes a big difference.

Thanks. Any suggestions on with combo to use now? 4.0.3 preferrably I guess.
Then why does my friend on totally stock 4.0.2, non-rooted have that great battery life from the first day using the extended battery?? I'm pretty much basing mine off of his and other's who are getting ridiculously long life. I never understood how it varies SO much. We should all have the same relative to usage.

No. Because no two phones are set up the same. Too many variables to say relatively same usage. For instance, when i go to bed i get 2-3 hours standby per percentage point. Not everybody is going to get that.

Maybe, but the fact that I have no other visible outstanding draining factors, and I get no 4G at home and therefore have it set to CDMA only...I should not be seeing 1% drops almost every time I turn the screen on for more than 30 seconds. Especially with an extended battery.
God forbid I want to use GPS or 4G.

..And over the course of only a few minutes of the screen being on maybe twice and sending one email, I saw it go from low 82-83 down to 77. ****ing awesome.

You probably have a misbehaving app. Download better battery stats from the android apps and games section here at xda and let it run for a day or so and see what processes are being used the most and what your wakelocks are, etc.
Also, find a 4.0.3 rom with a kernel that can be undervolted and try that out.

Thank you, downloading now and will check it out.

I'll admit I'm using the GSM version so my experiences may not apply but for the first few days my battery life was utter crap.
Its been MUCH improved over the last few days, I dont have the wakelock issue and with the screen off the battery drain is literally only about 3% per hour, and thats with background data on.
YES, the screen DOES use a lot of battery, it isnt really avoidable and is somewhat expected with a 720p 4.6 inch super AMOLED screen.
The one thing I can recommend doing is finding a modded kernel and undervolting that CPU - It seems they've been really rather generous providing power to the thing, I've been able to take off at least 100-150mv across the board.

This - My battery on the stock battery on GSM sucked first few days, and I was really concerned I made a poor purchase. But with the screen on probably 5 or 6 hours of my work day it lives through the day and just enough to get home after that. I can charge it at work too, which I usually do. On my day off it survived 18 hours and still had ~20% battery life left on 4.0.3 AOKP/Francisco.Franco Kernel

From my experience, the battery life isn't bad. I did install the "extended" battery as soon as I bought the phone but is isn't much bigger than the stock battery. I am on stock rooted 4.02. With LTE off I use about 2% per hour in standby. With LTE on it is almost double that (3-4%/hour). I have several widgets running and gps enabled. (wifi when available) I can easily get a 16-18 hour day and have 50% remaining when I go to bed unles I sit around gaming for a couple hours.
I may try a new ROM tonight but I expect it will probably make things worse.

Im running a bone stock setup and im getting 12 -14 hours a day... normally I read posts like the one skiddingus posted and wonder why I never can achieve those readings so i feel your confusion . I do have 4g on and gps off screen is about 1/4 of the way up brightness wise

4G Battery Drain

Hey, im on Telus so i dont have any other modes I can switch to to lower the drain. Ive noticed my battery drain is HORRENDOUS
Over the past 4 hours ive dropped 60%!
Now im wondering if im just running too many apps or if my stock battery may not be holding a proper charge anymore, and wanted to compare with others to see if others are running the same amount of apps and getting better battery or what
Ive got the following on:
Trillian (IM app)
K9-mail checking 2 aps
Regular Sync (Twitter, FB, Dropbox, Google(Calendar, Gmail, Contacts)
The battery usage summary seems to lie, 35% is the screen but only 13 minutes. Yet im at 40%
Android System at 20, Cell standby 13, Phone Idle 8
While heading to work, i ran DI Radio(music streaming), and lost 20% over around 35 minutes.
Im using the Tuesday rom with it's default kernel.
Is there anything I can do for better battery, because I dont have wifi in most places, and im running 3-4 bars constantly yet the phone just drains rentelessly. Even my Mugen battery was only lasting 16 hours...

It's quite possible that it's the ROM. I used to always get 8 hours on a single charge, regardless of location or ROM. I'm running Eugene's CM7 and I'm getting 13 hours on the same typical usage.
I'm running on Telus as well, with no wifi at all.
Although I am not running all of your apps, I would still consider myself a moderate to heavy user.

Its been a while since ive run juggernaut. But it used to only drain 10% an hour i believe on 4g. I've restored my nandroid of Jugg and will be monitoring that.

any syncing or usage of the network will take a drain. any usage.
you can always turn on airplane mode and let it sit a few hours and see the drain, that determines whether its network or a ROM/kernel drain.
But yes, using 4G has big battery cost

Battery Life
I will tell you what, I have wasted so many hours playing with different ROM's and what not to find the one with the best battery life. And I will tell you what, the DARKSIDE:IGITAL::WARFARE ROM's out do any other ROM out there. I dunno what it is that thederekjay is doing, but Samsung should get this guy on pay roll because his work is the best.

I'm at hour 8 today on Darkside Digital Warfare, and 70% free from 8am to 4:30pm. I have push corporate email, automatic brightness, friendcaster push, and a slew of accounts and it runs like a champ with amazing battery.

Make sure your phone is going into Deep Sleep as often as possible when screen is off. My phone seems to be extremely picky in regards to which charger it likes and more often than not (even had this happen on the stock charger) the phone refuses to sleep after being charged (even if only for a few seconds...).
Download CPUSpy from the market and after each charge, go to CPUSpy, press menu and Reset Totals (phone cannot enter Deep Sleep during charging so it's important you start fresh after a charge to get accurate sleep time). Turn the screen off for a minute or two and turn it back on. Press menu again and Refresh Totals. In my experience, if the phone is not sleeping at this point - Deep Sleep showing in Unused States - then it will not sleep all day and remain in 384Mhz for hours, killing the battery rather quickly. From then, if I plug the phone in a supported charger (even for a second) and disconnect, Deep Sleep resumes normally. Rebooting always fixes it too.
If, like me, a lot of people also have this problem with the stock charger as well, I bet many are dissatisfied with the battery performance... The phone is supposed to spend the majority of it's time in Deep Sleep. I get this issue with several different chargers and cables and on different ROMS / kernels (including stock... go figure).

Im pretty sure its the signal itself draining it. It uses sleep for at least 40% of the time its on. I use my phone a good amount, but its the fact that if it sits on 4g even with the screen of, its rapidly draining during this time. ive even reset timers and left it sitting for an hour and itll be in sleep but lose 8% over an hour just doing nothing. I still wanna be able to recieve notifications tho so turning off data isnt an option. I will test turning off data anyways to see if the drain stops.

The battery drain is all those persistent internet apps running. That is what you call heavy usage. Trillian and the FB app being the two biggest. Music streaming would be up there as well if you aren't in good signal area. Look at your battery stats and see what your signal strength is.

CleanRom 5 battery

Hi,
This question is for anyone using the latest CleanRom on their Note II. Just wondering if your average battery drain is around 4-5%/h. I use BetteryBatteryStats. I also check the Battery section under Settings. The most battery life I have been able to get is 12 - 15 h with 1-2h screen time. At this point, the battery is at less than 10%. Is this normal ? I thought I remembered getting better life from older versions of CleanRom. I know these numbers are never achievable on any AOSP rom that I have tried. Just wanted to see what everyone's experience is with battery life. Just post any thoughts!
Thanks for your feedback! I appreciate your time!

Just like anyone else, it all depends on what kernel you're on and what apps you have wakelocking. I've been using Clean 5.0 as my daily for months and the battery life lasts me throughout the day until I need to sleep at which point I plug in... but sometimes, I'm running into fast battery drain due to some apps going nuts on me or when Bluetooth is trying to link from a long distance (where the phone would heat up and drain like mad... btw this only happened to me twice in many months). After a reboot, it usually clears up and after a recharge, I'm back to 14 hours with 20% left at night. I'm not one to be anal about my battery drain if it lasts me until I sleep (because I have NEVER had a smartphone that would last me that long without plugging in... in fact, barely half the day would be when my device would need to be fed).
I'm using Perseus' latest with a few screen tweaks, no CPU or power tweaks, using Facebook constantly, Pulse, SMS/MMS, camera throughout the day, Next 3D launcher with all the fun animations running, YouTube, Pandora when driving (so my Bluetooth is on constantly)... let's just say I'm a heavy user. When my kids get a hold of my device, they run a bunch of games and drain around 10% by the time I get it back.
I am happy with the battery life on my Clean Rom 5.0/Perseus Note II. I won't fuss about it as long as it lasts longer than half the day because that is what I was used before upgrading.
