Quickest Battery Drain ever. What's yours? - Desire HD General

Now I know we all like to compare our battery life, brag about it and squeeze as much out of it as we can but how about we compare stats for the quickest battery drain ever?
Mine was
Fully charged 100%
3hours 25min Screen on time
3hours 10min modern combat: black pegasus, Multiplayer over WiFi
Screen brightness 40%
Battery left 10%
So in 3 1/2hours I manager to kill my battery.
What was ur quickest drain ever?

Sounds about right for playing a game for over 3 hours Do that with a laptop and youll get about the same.
Also depends what else you have running in the background.

Hmm I can't remember but i think it was like 4-5 hours on the first day
But I managed to get a 990 mA peak a few days ago

Under 2 hours
Using CM7 without battery tweak and a cheap Chinese battery
I was watching Big Bang Theory mixed with browsing the net.
I knew the Chinese Ebay batteries would be bad but I didnt think they'd be that bad!

Screen on (max brightness)
Gaming (Doodle Dash Pro)
Downloading (Mikes newest ROM)
Calling (Speakers)
Bluetooth & GPS activated (& active)
battery empty in 1:30 hours
(was for battery calibration)

Somewhere between 3.5 to 4 hours to 10%. I had screen brightness to 32% but the gaming time was for, almost, the entire period. If not games, it was surfing.

about 6-7 hours... was a cm7 nightly

Battery - up 'n running for

...4 hours of heavy usage (wifi connection and 3g on but idle)
Mid to periodical usage could reach 24h.
6th day of usage....
i think this is mediocre for me. please report your battery performance to compare.
Any tips to improve this?
I can get around 8-10 hours with heavy usage... constant music, etc.. and about 2-3 days with light-medium usage.

Hmm so i guess there is a problem with my device.
Great!, and how am i supposed to explain this to the service?
I get about 12 to 15 hours of heavy usage via web, text, and email. If i watch video it's less but I am pretty happy with the battery thus far.

I can only get around 7 hours of use.
I have a problem that if i even dont use it, the battery still drain. I got it full charged and theb unplug it. About 8 hours later, it went down to 50%.
Is there any problem with my device?

same here. i don't know how you guys are getting so much better battery life. i can barely last a day and i don't use it all that much. maybe 2-3 hrs of surfing the web over wifi (not even 3g). i even used setcpu to underclock to 200Mhz when screen is off.
Maybe it has something to do with the very first charge.
When i unboxed the battery was fully charged so i drained it and had it charged for 8 hours. maybe it needed to be charged prior first usage.

Is that 12-15 hours with the screen on? Because that's much more than I'm seeing.
I've done a few measurements just to get an idea of the battery life. They are just extrapolations based on a few hours of runtime for each so they are by no means exact, but my impression is that they give a decent view of real values nonetheless. The battery percentage indicator does not seem to be terribly non-linear.
Video playing (SD quality) with full brightness: 5.5 hours
Video playing (SD quality) with lowest brightness: 9.5 hours
Idle at homescreen with full brightness: 6 hours
Idle at homescreen with half brightness: 9 hours
Idle at homescreen with lowest brightness: 12 hours
Music playing in headphones (screen off): 90 hours
Can't believe how lazy reviewers seem to be, I haven't read a single one where they have properly measured battery life for things like playing movies or reading an ebook. It's all just subjective feelings (which are obviously very unreliable).
All in all I am pretty pleased with the battery life (but I've just had it for a few days). I especially like the fact that it's basically a normal Android phone just with a giant screen and battery. This obviously means that standby and music playing times are going to be excellent.
Edit: Those of you who think you're seeing bad battery life, what does the battery use thingy in settings say? Or is that not a good tool?
I read a post somewhere where the OP was getting horrible battery life and found out that the Gallery app was draining the battery.
The OP in that thread said even exiting the app did not kill it, and it kept draining the battery.
Perhaps you can look into this more. I never use the gallery app so maybe why this is why i get decent battery life?
Edit to add:
Here is the thread
http://forum.xda-developers.com/showthread.php?t=826472&highlight=gallery
If it's this post you're referring to it's by me . The Gallery application shows up under battery use though, so I'm pretty sure that's not it.
Are you sure it's really as much as 12-15 hours with the screen always on? If it were 9-10 hours with brightness at half it would around what I'm seeing I guess, but 12-15 is quite a lot more. Not that I'm disappointed, but if better is possible better is what I want

No not 12-15 hours with the screen always on.... I get 12-15 total... Screen on for usage, off for a while, back on to email and SMS ect...
Ah ok, then there's no discrepancy .
I got 10 hours from full to complete off. I was using it to watch streaming movies on 3g
for a couple of hours and then watch a movie off of the sd card and an episode of supernatural.
After that its just web and ebook reading. Its pretty good. Almost the same as my ipad.
I got a total of around 14 hrs plus with wifi and edge on, screen brightness at 20%, around 7 hrs of standby while i was asleep at night, with 4 hrs of heavy surfing, youtube etc. . . No calls though, only some sms and always on IM with nimbuzz logged in.
What i am seeing is with heavy usage i.e. Multiple apps running, wifi and edge on, i get anywhere between 5-7 hrs of battery life which i think is fair enough for a device this size which am constantly fiddling with.

I've not used mine for that long, but the Battery Left app(which I found to be quite accurate on my N1) shows that for MY usage, I'll get about 25hrs.
I've got the auto dim turned off, and brightness at max. I mainly use mine for checking emails, txting, and a few games.
Nothing heavy.
I'd recomend the Battery Left app to you guys looking to find out your battery life. You DO have to "train" it though, which requires a 100%-0% run for you.
Guys,
does.anyone know, do we need to cycle the battery to give it the best performance?
Example, charge up the unit, then drain it completely and recharge it again? Like in the old days.
mine hasnt gone down much. I have it unplugged at 6am and at 4pm i still have about 75-80% batt left.
This is with about approx. 2 hrs of talk and 30mins of data usage and voice calls paired to my BT headset. My screen brightness is set to 40%

I once got up to 20 hours of moderate usage. But with heavy usage I get about 12 hours or more. I lose about 7% when watching an episode using flash....kinda sucks but I watch a lot of anime online. But I use this as my main phone too. Its replaced my nexus completely. though it was nice with my nexus cuz I could swap batteries. This is how I condition my battery. I let it get to about 2-5% then I recharge it. I don't let it get to zero cuz I heard you can damage the cell. sometimes I charge it to about 20% then I unplug it and drain it to 5% then back up to full. I just kinda switch it up. At first I was getting horrible battery life but ever since I started conditioning it this way I get great results.

battery usage assessment

I decided to test - on my DHD with Current widget - how much electricity does different hardware parts and softwares use.
I test the battery usage with different brightness settings, wifi and mobile internet download, call, call over bluetooth, music, games, etc. I do it with stock battery, and with LeeDroid 1.4.1 (what is 1.72 based and uses stock kernel) Most tests made in flight mode to make as accurate as possible.
Now, the battery is 1230 mAh what is 1230 mA x 60 minutes = 73800 mAmin. It means if the phone uses 123 mA, than it would last 10 hours (123 mA x 10 h = 1230 mAh). And if the screen uses at least 73 mA, than ( 1230 mAh / 73 mA = 16,85 h ) it won't last more than 16,85 hours with screen on. And it means that only the screen is on on the lowest brightness. So don't expect more than 16,85 hours if you continously browse, play, chat, etc.
Screen:
In flight mode.
I took the lowest number, because the screen uses what it needs, and sometimes some process starts.
brightness---->usage
0%...............73 mA
15%.............76 mA
30%.............92 mA
45%.............107 mA
60%.............125 mA
75%.............149 mA
90%.............172 mA
100%...........191 mA
If nothing else uses much electricity, you can expect 10-15 h screen on, on average brightness.
Music:
In flight mode, screen off.
Normal text - speaker; bold text - headphones; normal text - active speakers
volume------>usage--------->usage---------->usage
0.................49 mA.............52 mA.............50,5 mA
5.................50 mA.............54 mA.............51,5 mA
10...............55 mA.............57 mA.............52,5 mA
15(max)........75 mA.............62 mA...............55 mA
It's enough for about 24 h music with volume on around 10 (in flight mode, screen off).
-Real life test:
Today morning I used my phone for listening music only. It playd music for 6,5 hours and it used 30% battery.
It is 4,6% per hour.
There was no flight mode or other special settings. Of course wifi, bluetooth, etc. were turned off.
It means, that it used 56,8 mA, what is quite good, and a full charge lasts for 21,5 hours with this usage.
Download:
Screen continously on lowest brightness, what uses 73 mA
wifi..............220 mA - 70 mA
3G...............300 mA - 70 mA
GPRS............100 mA - 70 mA
It took 30 sec to download over wifi and 3G, and it downloaded 10% in 6-8 min.
So I recommend wifi. Don't forget it at home!
Navigation:
Maps and 3G and GPRS
It used 350 mA with both settings.
I will test the Locations tomorrow and see if there's a big difference.
Games:
Low brightness.
Need for Speed - Shift ....................... 315 mA

Either you can't be arsed reading around to get optimum battery usage out of your DHD (wifi off when not in use, battery calibration etc) or you have a hardware fault! My battery easily lasts 15-18 hours of heavy usebetween charges (currently at 78% after 11 hours unplugged albeit with moderate use)

I'd relay like to know how you have achieved that kind of usage with heavy usage, I can get my DHD to last the day, but its always giving me 15% or worse warnings by 11pm after being unplugged at 9am. I don't use it excessively, bit of browsing, screen on auto, bit of music. The battery life has gotten way better since I got the phone. Does calibration name that much difference, I run the phone basically right the way down every day as it is.
Just be nice to use it as much as id like to (aka not use it and worry about it dying) and still last the day.
After doing the battery reset, I finaly got through the hole day with heavy use, without worying that my battery runs out. If you havent done it yet, do it! Tried diffrent methods, but the one that worked was the one that HTC recomended. Charge with phone on for 8 houres, unplugg charger, shut down, charge for one houre, unplug, turn on, wait two minutes, shut down and charge for one houre. Remember to disable the fastboot befor shutting down phone.

Don't tell me!
I finish my morning job at noon (I start 5:30) and it's around 20% left.
I'm thinking of buying an 5000 mAh external battery. Than I would not worry about using as much as I want : )
Music seems to be using quite low of power.

There are numerous posts in these forums where people have doubled their battery life by calibration, I won't claim any such results as I fiddle that much that I can't really pinpoint one factor, so yes it can I believe what is happening is that as the battery improves with charge cycles the dhd is assuming it's capacity remains the same so with calibration you are resetting the max charge level

Can you list down the items under "Android System Process"? I am using my phone roughly the same way you mentioned on your other post but I'm at 8-hours with 80% left. Maybe you have an app doing the damage.

Amazing batteries

Xoom and honeycomb truly have the best battery life I have ever seen. I have been using mine for at least 15 hours straight and my batteries are still at 53% left. I've been using this extremely heavily with 3g on for like 10hrs and wifi for the rest of the time....gaming, web browsing, emailing, pulse reading, remote connection, and even some video!
According to my batteries,

Agreed. The battery life on this thing is amazing, way beyond what I expected.
Been playing with it on and off all day at work, now, 13 hours later, I got 71%left. SICK.
I've been really happy with it too. Had it at work yesterday. I brought it to work at 90%. Connected my bluetooth headphones to it, streamed Pandora over wifi through the device to my headphones non-stop for 8 hours. Used it for checking personal mail and a little bit of browsing so the display was probably on for an hour of that time. Got home and the battery was at 65%. Excellent!
I feel like mine doesn't get nearly the battery life that you guys are talking about...using it constantly with the screen brightness turned all the way down it seems to be getting roughly 10 hours of continuous use on wifi.
Are you all rooted? I don't think that would matter but it seems as though im a little dissapointed in the battery life where everyone else is stunned. I had the screen off last night at around 50 % and this morning at around 11 it was at 11%.
Should I be worried?
there should be multiple threads on this!
THE BATTERY LIFE IS INCREDIBLE!
14hrs and with that included
5hrs display on (over 75% brightness if not full)
1hr20minutes on google talk video!!!!!!!
(5minutes of wich i tethered my nexus s and used my 3g rather than wifi..which by the way was both just amazing) seriously, i kept switching back and forth with the camera to mess around with my sister...simply amazing.
2hours browsing
45minutes movie
28% battery remaining!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Dude, that sounds about right. If you are saying you used it for 10 hours continuously with the display on (which is easily the biggest drain) then you did well!

lol. This made my giggle.
Anyway, maybe he was refering to having apps running (ie, pandora, browser, etc) with the display off for the rest of the time. Granted, the display pulls the most battery usage, but the device can still be in "use" with the display off.

Valid point.
What's the best way/time to charge?
How and when do you guys/gals usually charge your Xoom?
Plug it in every night to charge overnight
When it's almost dead (<10%)
Plug it in whenever possible
Other
Just wondering if any of these "techniques" will affect battery life in the long run!
overnight to charge usually. i havent been able to kill the batteries during normal usage.
Had mine off the charger for over 48 hours. Just put it on the charger this morning with battery at 10%

I'm blown away by the battery life on my Xoom. I left my charger at home on my last trip and went 3 days without charging, with moderate use I still had 20% when I got back home.
I personally charge every night, but I really don't have to. I use it at work, check emails, take notes during meetings, etc. Screen is prob on 4-5 hours a day. When I get home, more browsing, maybe some music. When I finally get to bed, I usually have >50% battery.
The batter is so good, I basically solved my one big gripe, which is power button. During a meeting when I know I'll take notes intermittently, I simply set the screen to never go off. It does kill the battery, but I have still never had a problem getting through a day.
The 2nd day I had the Xoom I stress tested the battery, used it almost the entire day, barely put it down. Got through 10hrs with 20% battery left, browsing on WiFi, some gaming, etc. Last night, I went to the American Airline Center to see the Stars, about 3 and 4 hours of hockey(went overtime then shootout) and only used about 20% battery in that place, which is usually a horrid battery sucker on 3G on my Droid.

2)discharged till phone shuts off
3)turned phone on again so it turns off again
4)went to sleep with it charging

I'm wondering the same thing... the Desire Z only comes with a 1300mAh battery... My previous phone had a more powerfull battery (2100mAh) and that was an older model WM6 smartphone (which was rubbish on power savings) and it would outlast the desire Z... Even after two years of extensive use, the old phone's battery is better then this phones brand new battery
I've been unable to find any official HTC batteries for the Desire Z which pack more juice...
At the OP. What is your signal strength like? Mine is rubbish at work as I work in a converted barn and that makes a big difference to the battery life.

I am in the process of 'breaking in' a new 1800 MuganPower battery. Fits perfectly with no mods needed.
It should take a few more charges etc to settle down, so things should theoretically improve.
I pulled the plug off charge 6.5 hours ago.
I have it set to use wifi when at home, and 3g for the phone connection (I have a 3G femtocell at home).
When I leave my home area, it switches off 3g and wifi and drops to 2g.
I have made a couple of 2 minute calls, checked my emails and twitter, and was out of the house for say 1.5 hours earlier.
I have had a couple of texts to which i replied.
I am on 95% charge now, and pretty pleased with that.
I've got the same mugen battery, and get through a full day easily no matter what I do. Screen full bright, wifi always on, some internet, games, gps.... etc. Only 7 hours of battery to me sounds terrible.
since my last post, i havent touched the phone at all, and its got 66% charge -__- i seriously need a better battery, may buy the mugen, would you say they are worth it?

Are you using the Google News and Weather widget? I still don't know why, but it was murdering my battery. Soon as I removed the widget, battery life shot back up.

nope, no widgets except the built in analogue clock.
the battery usage is used by mobile standby, wifi, display etc. no apps....

What percentage per section(standby, display) is being used?
Sent from my 'SilverBullet' HTCDesireZ running CM7
mobile standby 33%
wifi 28%
phone idle 28%
display 5%
im surprised its been 10h 15m and im still on 58%
the battery seems okay when not touching the phone, as i have only checked facebook for 2 minutes, and sent around 10 texts (been playing football)
looks like imma turn off wifi when not using it from now!
When I first got my Desire Z when it first came out I was pretty disappointed in the battery life. I tried programs like juice defender and minimized every possible battery sucking option I could find. I could maybe get 12 hours of use out of it so I bought a 1800mAh MuganPower battery which gave me maybe 15 hours instead. Pretty poor I thought but what more could I do?
A couple of months ago I finally did a factory reset after encountering a lot of frustrating little bugs, some of which had been around since the phone was new. Since then not only has my phone worked a lot better and faster, but battery life is MUCH improved. My phone now consistently lasts 24 - 30 hours with the same usage or more than I was using it before. So obviously buggy software can make a huge impact on battery life and it's not something you are going to be able to easily discern as to what program(s) are causing the problem.
Hmmm im not sure then..

Okay, played a bit of speedx 3D, heavy texting and facebook/gochat, still on 31%. Battery seems ok, still going to invest in a better one though, as using the phone for games or internet heavily drains the battery, whereas standby seems to be quite good, but need to turn off wifi. I will see how it fairs tomorrow, and post a picture.

28% for wifi seems really high. I always have wifi on and it only takes up 6%.

Your battery life so far?

At the moment it seems like I'm getting around 5 minutes per percent (around 8 hours of constant use). The weird thing is that seems to be the case across all use, I get the same results from web browsing as I do reading comics in airplane mode.

I get pretty incredible standby though with set cpu. I'll go to work and come back after eight hours or more with one or two percent gone.
Yeah the standby life is amazing

set cpu app helped me get amazing stand by times. i mean i lose 1% every 24 hours propably.
during normal use, i get average 4-6 hours. surfing youtube, downloading, playing games. usually 5 is about right. People who say they get 8-10 hours heavy use are on one.
I would agree with 4-6 hours with constant use such as reading or twitter browsing. I previously had a Nook Color with CM7 on it and got about the same. Standby is amazing I almost never turn it off.
After about an hour of surfing or playing a game I lose about 20% so about 5 hours. But when watching videos I get around 7 or 8 hours

This sounds awesome I just got 48 hrs on included 4--5 hrs of use. Down to 2% ... wifi is set to go off with screen (after 1 min) not. Sure wat else to change
Hmmm. I was hoping that rooting/SetCPU/screen settings could get me closer to 8 hours of life, but that's not the case. I'll probably just sell the Iconia since the battery life is my main reason for owning a tablet, and in this case it isn't that much better than my laptop.
Run time.
52 hrs. %79 & moderate use. Never shut it off & still testing. Want to see how long it can go until I reach %30.
not trying to be an ass, but what are you guys using your tabs for? i run taboonay rom with thor kernel and good to very good battery life. I use my tablet all day long at work for e-mails, pdf viewing, gaming when i shouldn't be, and playing around on the internet. I wake up at 5 am everyday unplug my tab and start the day. With said usage i can go from 6ish AM till almost midnight and still have 20-30 something percent battery left. I wouldn't say i use it hard core, but i put it work. Just charge it while your asleep and it should last all day. Now on the occasion i watch movies on it it does drain the battery like a bastard but i can still get 5-7 hours of non stop movie watching on it. I really can't complain about the iconias battery at all. If you expect this thing to run like Carl Louis all day long without plugging it in you're in lala land. Theres alot of threads on how to get rid of cell usage drain, and look at whats killing your battery it may be an app or something you did settings wise to drain it faster.

Completely agree, I got mine on Saturday and apart from the initial charge it's only been plugged in twice. Used on and off throughout the day on Sunday, most of Monday evening, all Tuesday evening and all Wednesday evening, playing games and on the web with a bit of youtube and playing around. First time charged at 35% on Monday evening, second time yesterday at about 11pm as it was down to 10%. I think that's pretty damn good myself. It's on OTA 3.1 and Rooted
As for comparing to netbooks, have a look at the size of the battery in a Netbook compared to the Iconia. Of course they're going to last similar amounts of time - The Iconia has a smaller battery but has less to power versus the netbooks larger battery with more devices to power.
I'm at 67% after about 27 hours with about 2 hours of actual use. I guess that's ok. I flashed the Minimalist rom on Tuesday so I probably haven't given the battery enough time to break in. Sorry for being a *****, I'm just impatient >.<
I was kind of afraid if it would last me through a day of classes when college starts back, but I think I'll be ok.
I was getting around 5 days total with 1 to 2 hours display usage before the update to 3.1. Now it only goes 2 days when on standby with less than an hour of usage. Going to download SetCPU and try that. I have not changed anything (widgets) since before the update, so I have no idea what's eating up the battery.
Does anyone use there tablet in this post?Lol
I use my tab all-day long and I usually have 20% by the end of the day.

I use my tablet about 4 hours a day
I have to charge every 2 days
I charge during 2H30 arround.
Mine has been doing pretty well lately. I guess flashing roms took its toll

setcpu settings?
I'm using SetCPU as well, but getting no where near what you say. I left it on sleep last night and it drained 15% - same as before.
But, maybe I'm not using it right. I enabled the "screen off" profile and dropped the speed.
What are you doing/setting to get that standby time?

Ok, I activated a couple more profiles including "time", temp, low battery. Low battery definitely turned on and I saw the change in the icon on the bottom right. I think the "screen off" is not turning on - basically can't see it when the screen is really off . But, it's definitely draining the same amount of battery.
Am I doing something wrong?

SetCPU didn't help mine either. Tried a few different profiles. I thought the one that would help the most is Screen Off, I set it max and min to 216mhz. No difference in battery drain overnight.
