Wow I don't understand how you people get such amazing battery life!

I am no noob anymore regarding Android and Smartphone's in general, so I understand most 'hints & tricks' in this thread. But simply for me this does not work.

Some important stuff:

- I ALWAYS have 2G on, never 3G.

- I use wifi at home and in most places I go

- I have almost everything set to 'manual' updating

Ok.

For example my last situation:

I unplugged it at 23.30 yesterday. I used it for a little bit, over wifi. Checking twitter, surfing the web, watching some video's in HTC Flash Player. I went to bed around 02.00, watched some Law & Order that's why it was so late. So before turning off the lights, I turned wifi off. The battery was around 80-85%, from what I remember.

I wake up at 12.00. The battery was still above 50%, that's for sure. I do some facebook, twitter, news, etc. All over wifi.

And now, just before 17.00, my battery was dead (while I almost typed this entire story on my Desire -.- I was pissed). So that means, about 17 hours? Which about 10 hours I slept and the phone was doing nothing, over 2G!

So yeah... and when I read all your story's about 2 days (48 hours) I am really like: WTF :confused:

Some more details:

-No live-wallpaper. Just the black 'carbon' one.

-I used to use LauncherPro beta, but battery life was just as bad. Now I am back on HTC Sense. I have some widgets, like the Calander widget, a small music widget, bookmarks widget, etc.

-I tried to find out what uses the most battery while sleeping with that code and it showed Android System. So nothing weird there.

-Again, everything set to MANUAL updating

-ONLY 2G.

-Brightness set to auto.

So really, I think it's my wifi that sucks the battery life out of my Desire. I remember when I went on a trip and was just 'listning' to music, my battery only dropped like 10 to 15% in 3 hours.

-----------

Btw, I remember that this 'some people have great battery life some people don't' story was the same with the HTC HD2. The only different thing there was that I was one of the people with the 'good' battery life. Now I am on the 'losers' team :(

Any help would be great!
[Desire General] Tiger33:
Yes of course

my point being that I use the phone in the same way as before but previously it was just lasting a day.

with the new juicedefender and turning off mobile data I can get more life out of it as well as still using the phone in the same way as before.

I have good speed with my 3G so dont need to use WIFI for emails or browsing so it doesnt make sense to turn wifi on when i'm out anyway.

The whole point of this thread really is to check what everyones battery usage is and also to try and identify applications or settings which cause high usage.

its obvious that general usage will kill the battery but of course that's not the point here.
[Desire General] Tiger33:
Here are the things which I have noticed really eat into battery

Screen on - i.e using the phone.. of course

Screen Brightness high

Alarms - I noticed this when using JuicePlotter

Widgets that sync and download

too many widgets that pull data

poorly coded apps which do not sleep properly

Wifi searching (but wifi dorment does not use much at all - maybe less than 3g in fact - based on juiceplotter stats)

The alarm battery usage really shocked me

so it would be great if others could test this too - basically I used Juiceplotter (great free tool by the way)

over the night I checked the battery usage line in JuicePlotter and noticed that at 6am the usage dropped rapidly for the next 20mins (this is the time that the alarm was set to turn on).

Before this point during the night usage was 1%

after the alarm went off usage was about 12%

anyone else noticed drops like this with the alarm?

(I tested with a custom alarm app - Gentle Alarm and also the default alarm - the same thing happens)
[Desire General] streetdaddy:
To anyone using Juice Defender, did you have the problem with Mobile Data not renabling? I was having to reboot the phone to get Mobile Data to turn on again, very annoying... just wondering if anyone had the same problem and was able to fix it somehow?
[Desire General] Tiger33:
never had this problem myselve but heard alot of people did -

it may be worth joining the juicedefender group mate (google group)

and downloading the beta version which is vastly different to the current marketplace one - this may fix your issue.

- I remember with the old version of JuiceDefender it was renaming my APN which was causing some problems

check the JuiceDefender log and it will tell what is happening - u may have some way of working out the problem from that, else just join the group
[Desire General] danielletch:
Using the *#*#INFO#*#* im showing UID10059 using 4 to 5 times as much power as android system on Partial Wake Usage!

Anyone know what this is, ive looked all over the phone and SD card and cant see it listed anywhere, is it an app?

Unplugged my phone at 7am, its been sat on my desk all day with juicedefender working and less than 11 hours later its on 60%
[Desire General] kinkade:
Yes, how do we tell what each UID means? i've had this show up a couple of times and have no idea what each one is.

anyone have any ideas?
[Desire General] dexteral:
is thre a way to have seperate timeout for the buttons backlight e.g. when i am playing a game (fully touch no hardware buttons like robo defence) i notice that the backlight of buttons dont turnoff. perhaps this also drains the battery.

maybe there is an app/mod which enables seperate timeout for button backlight?? like 5sec after i press any button
[Desire General] Dunbad:
A few people are saying turn 3g off, im not convinced about this. Turning 3g off and having 2g on with the phone in standby mode uses extra battery than having internet turned off completely surely? There is a stock widget that turns off data connection. The power saving widget turns off gps, wifi, bluetooth but NOT data. However I found a widget that controls just the internet. I simply turn this off when im not using the net. When I wanna go online, I hit the internet icon and sync icon if I wanna check mails etc and im away. Also Im of the impression that 3g, in standby mode, uses LESS battery than 2g, in standby mode? Furthermore im of the impression that wifi connected, uses less battery than any connection (so long as its connected and not hunting)

Either way, I get good life out of mine, but just connect when I need to, with manual updates. I get a days use out of mine and I cane the hell out of it.!
[Desire General] zkyevolved:
this is a drepressing thread to be honest.

I'm a hardcore blackberry user. My blackberry bold 9700 has the absolute greatest battery life I've ever seen. After HOURS and HOURS of music and instant messaging I'll finish the day with 60-70% with 3G off. If I leave 3g on all day I'll end up with about 40-45%. This is depressing to see how people turn off 3g, turn off data and everything just to last a day. I REALLY hope this isn't the case.

I ordered my Desire yesterday morning (yesterday was a holiday so I don't know when I'll get it, but either Monday or Tuesday, and i'm so excited). I really hope it can last at least 9 hours of VERY hardcore usage.

I haven't really been a big fan of Android until recently, but when Blackberry storms were being compared for battery life someone took a video and put the device into 100% offline / airplane mode and put the video in repeat (usually a movie encoded for the device) and played it on repeat until the battery died. Has anyone done that one yet here?

What can I expect from the battery life?

I plan to leave google talk on always (or almost always) and also Push Email. I contact people via email almost always. I also listen to music about 2-3 hours a day.

Can I get a real life answer? What can I expect :S?
[Desire General] Dunbad:
I think from my experience, you'll JUST squeeze 9 hrs HEAVY use. Put it this way, I have an hours train journey to work, this is spent listening to music whilst browsing the net. Then i "work" for 8 hours, if its not busy at work like its not at the moment, I can spend 5 hours giving it large internet usage, youtube, etc.twitter facebook etc.Then I get the train home, when I get home, my phones working on only a fart and a prayer. But like I say at work I spend alt of time streaming videos. If is busy at work, ive still got 50 60 70 percent battery left when I get home.

Just to add, my phone is not out of my hands for those 7 hours. Also for some reason my battery took a full two weeks to improve. Initially I was getting like 4 hours punishment out of it. The only reason im not too disappointed is the punishment I put it through. Need another battery and dock at work!
[Desire General] Noodled24:
I got my phone yesterday and was messing with it all day, Wifi was on all day, I got about 5 or 6 hours.

It was on charge all night. took it off at 11am. by 11.20 I had 94% battery. By 12 it was on 89% and i'd barely used it.

took it to work, no wi-fi. listened to music for about 20 mins, the rest of the hour i was on the web and on msn. 3G was on all day. I used navigation on the way home, just to test it. had about 30% battery when I got home.

Heavy use I think you'll get about 5 hours.

Moderate use... I cant really say yet because its my new toy and i keep messing with it. But it seems comparable to my old blackstone. You will need to charge it every night. But i'll go a good 20 hours.

Was a bit worried this morning when it had discharged 10% in under an hour. I have a task manager which is usefull. But I seem to have a lot of apps running, "footprints must load at startup because I've NEVER used it and it's ALWAYS there!
[Desire General] Tiger33:
thats what i'm doing mate

at first i was getting about a day or just over

now i think ill get to 3 days with the new settings (as listed above)
[Desire General] zkyevolved:
Lol. There is no way I'd get 3 days with my Blackberry. My 9700 takes about .5%/h with random messaging and 3% with hours of hardcore messaging. I have to admit, I'll miss this. Blackberry is the BEST for push messaging and data compression. But I'm trying to get away from Blackberry. I know i'll get less than perfect battery life with another device. But I REALLY hope to get at least 9 hours hardcore use, and 18 hours of normal use, writing about 40-50 emails a day. All I can say is that if I fall completely in love with this device is that I'll invest in a mugen extended battery if I can't make the battery last all day super hardcore. :D.

I'm totally pumped for this device :D I was between:

Nokia N900

HTC HD2

Nexus One

HTC Desire

and

stay with my BB 9700. CYA!

Lol. I haven't been able to stop reading forums and reviews about the Desire. :)
[Desire General] Kloppy:
Dont know if its been suggested yet, but i underclocked my desire to 500mhz and got clearly better battery life out of it. If i really need the speed, i can always oc its to over 1.2ghz with just 2 clicks. :)
[Desire General] mijanous:
Guys u would say its not possible to squeeze so much from desire but with data and wifi off, few times i browsed web,some phone calls some gps and i got 4 DAYS 6 HOURS

But under medium to hi load it drain pretty quickly but still its ok i think

Under heavy load, my BB Storm would lose 10-12pc/hr. This Desire is a dream come true compared to that. Still, battery charge gets absolutely raped when long making calls. Internet and video seem to fair well on battery life, making calls doesn't.
[Desire General] XDA mark:
Thank you.

Btw, again I unplugged it for 2 hours. Did not use the phone AT ALL. When I look, 89%. I look and cell standby had 48%, phone idle 46% and Android system the rest.

2 hours doing nothing. And it dropped 11%. Im on automatic mode now since you guys say there is no big difference between 2g/3g (no internet connection). I am in the city so now bad signal.

I checked the partial wake usage: nothing special.

Edit: typing this story in a few minutes, now I am on 84%. So 5% in a few minutes? Screen brightness auto.
[Desire General] zkyevolved:
It takes more energy to maintain 3G than it does 2G. I don't know of any apps off the top of my head, but can check what number it's at to maintain it. To maintain my Blackberry on 2G it -70dBm. On 3G it's a lot higher. Not to mention adding in that it has to sort between the two, searching for signal. 2G uses a lot less energy, that's a fact. :).
[Desire General] zkyevolved:
I used an app, BatteryMeter, on my Storm and Bold, and the storm on GPRS / EDGE would get 2% at idle (no use at all) drain, and 12%/h while using it non stop without turning off the screen. On average, checking messages, chatting for 5 minutes or so via BBM and MSN and GTALK and such was about 8-9% drain/hour. That's not bad for constant in / out data :). 3G raped ALL my blackberries :(. I once got my Bold 9000 from 100% - 25% on 3G BBMing in about 3 hours. Sad.

I just want an awesome device that can last about 9 hours of VERY Heavy usage on EDGE / GPRS. Not to mention a cool device :) If I wanted a battery lasting device, I'd stay with my 9700 which only does messaging well. I want some cool apps, large screen, beautiful display. The desire is the device for me! Let's see how the battery holds out :D
[Desire General] JagSem:
I used Meterberry, paid for app. The Storm was a strange device. Sometimes used to average 0.5% on Idle upto 7-8% even though nothing was running bar standard apps minus BBM (didnt use it).

I want to find an app on the Desire that will display the battery usage of all the running apps to see which one's are consuming heavily. I havent looked for one yet but will do at some point.
[Desire General] zkyevolved:
oops, yes, that's the app I use. Lol.

Well, if you find that app! Let me know :) I'd like to know this app if it exists :)
[Desire General] Tiger33:
folks u need to install juiceplotter or battery graph to really understand what your battery is doing whilst idle
[Desire General] A|ex:
I get just about 3 days.

That includes:

Widgets, clock with auto updating temp (3hr), aura widget x2 (auto notification), weather channel widget, facebook widget(3hr update), twitter widget(3hr update), stockmarket widget (3hr update), power control widget, and photo frame widget of my cat! Mail is set to auto check twice a day.

Wifi usage is around in the 3 days roughly 1hr - 2hr this is for use with a lot of twitter, facebook updates and mail checking.

GPS use with endomondo is close to 2hr in the 3 days.

Phone usage can range between 100 - 200 mins.

Robo defence is 1hr - 2hrs (no sound)

Then phone is totally flat. Its nearly the same as when i had a HD2 but i managed to get 4 days out of battery.

If i want to totally drain battery i fight up copilot and that will drain my battery within a few hours of usage!

I dont use any battery monitoring application as these all tend to drain battery and every two days i kill tasks that are left open by apps. 3G always on, i cannot live without 3G and i do not get any gain from battery life from turning it off on my phone. I did on previous phones but this phone the battery still is the same with 3g on or off and i am in a 3G area
[Desire General] Desirefan:
I'm getting 2 days of decent use out of mine now, but the first 2-3 weeks I had the phone it was much less, sometimes barely lasting the 11 hours I am out commuting and working, and that was with minimal use. Gradually battery just seemed to improve on its own. I don't use a taskiller or juice defender as I sacked the latter off when I had problems with my apn being renamed and data connection issues. Not rooted and on original t-mobile uk rom that it came with.

I have sync on (hourly), wifi on, 3g enabled, loads of widgets (mostly stock htc ones like weather, notes, friendstream, people, etc apart from 3 cubed music player and battery widget) and use phone daily for about 2 hours music/fm radio, 30 minute approx on calls, plenty of texts and emails and about 20 mins web browsing. Generally it is at about 70% after the first day, then loses another 5% overnight (with everything left on and phone just in standby) but is usually at about 15 or less % when I get home from work the next day.

Weekends I charge every night as I use it more - virtually constantly.
[Desire General] JagSem:
dl'ed JuicePlotter. I dont get why the plot line in the graph is blurry. I dont understand the different colours either. What i do understand is, if i hammer it battery dies quickly :eek:
[Desire General] Tiger33:
if u go around the line the top will tell u what they mean

(red is wifi) (i believe yellow is screen on - may be wrong)

just monitor the line - and when it dips by a large amount check the time of the dip and the color of the line (i.e if red u know its wifi causing the battery - if its not then maybe its an alarm during its sync run etc)
[Desire General] JagSem:
Oh yeh. Didnt see that, cheers.

Edit to say: It tells you battery charge ie 48%, tells you batt temp, screen brightness setting, and which radio is using power (wifi/apn)
[Desire General] Tiger33:
Excellent

let us know how u get on

- u should see it slowly go to no power - but inbetween there will be huge dips and the time

from that you can tell whats going on pretty easily.
[Desire General] XDA mark:
Thats insane! You left it for 8 hours with wifi on (and 2G also, right?) standby and it only dropped 1%??

Something is not right. This is totally not how my battery life is! My Desire is unbranded, a 'generic' ROM or whatever you call it. I am running the newest update that came out a few days ago...

Argh. I wish I had the same battery life as you! :( Any more tips? Settings that you think are very important, or apps?
[Desire General] iammt:
mine needs to be charged once aday
[Desire General] th3:
As lame as it is, I really have no idea... this one just is like this since the beginning. And yes, mine is one of those known to last 3 days on low/basic usage. Check my previous posts where I detailed.

Yep, 2G was on alternating between 0-1 bar as usual, WiFi at 2 bars. WiFi auto shuts down when the screen enters standby. I'm not sure what happens with the cell radio. 1-2% drop for me is very typical from sleeping to waking (night to morn, 7-9 hours is the norm with me).

I'm shockingly surprised it lasted through the full movie in the test - which played for around 2.7 hours. I was definitely not expecting that. Every moment during the vid when sections with high effects and CGI came, I was expecting it to shut off with a dead battery.

Intentionally, during the test I didn't check battery even once until I came back home towards the end. I wanted to basically force my pseudo-realistic high usage pattern to see how short it would last with my typical settings if such a day ever did arrive. I expected 13-14 hours with this usage beforehand. WiFi+multimedia playback is very heavy usage. There is no way for me to come close to this much incessant usage even on complete days off from life.

Now you know why the idea of reset/root/update makes me shrink back immediately :p

I'll keep testing...

[Desire General] huwwatkins:
Has anyone tried the latest radio in the radio thread? Does it make any difference to battery?
[Desire General] Noodled24:
The battery is VERY strange.

It seems to drop to about 89% in absolutely no time... 15/20 mins after taking it off charge. After that it seems to manage better. Still pretty shoddy though. If/when an extended battery is released I dont think I'll have any choice but to invest in one. There is no way I could make the battery last more than a day, and if I was doing any "heavy use" I think I'd struggle to get 10 hours.
[Desire General] zkyevolved:
Well, mugen released a 3200 mah battery, but it won't be out for another 2 weeks.

I'm personally still waiting for the Desire to come to my arms! If it's completely awesome and typing is easy and such, then I'll invest in the 3200 mah battery. :) I love data. I'm a data hungry guy xD haha.
[Desire General] john014:
guys, really what is the point in having a "super smartfone" that is "aware" if your just gonna disconnect it from the outside world?? I dont know about you but i bought this phone for its abilities, i.e. facebook/contact sync, not having to manually refresh my emails/notifications every 5 mins, and just the general smartness of what it can do!! in my opinion your crippling you phone just to make it last longer!! i have everything set to auto sync, thats 1 gmail acc, 1 exchange account, twitter app, facebook app and weather app set to the most frequent, 3g is never turned off except when im at home when wifi is enabled, and i still get enough hours out of it to allow it to last while im at work!! with time to spare!! i only charge it when i go to bed, and this is the honest truth! whats the point in having this phone, even if it does last for 4 lunar cycle on one charge, you may as well buy a nokia 1110!!

rany over.

sorry. :p
[Desire General] oursoul:
I was worried for a bit earlier.. I charged my phone to 100 then uplugged it and within a few seconds it dropped to 94

'oh ****' I thought and plugged it back in

30 mins later unplugged it again and it stayed at 100

in fact it still says 100 now and that was an hour ago so I have no idea what you guys are suffering :P

I've had fantastic battery life, I've been using it on and off for market downloads, updated to T-Mo UK 1.21 (using the link in one of the stickies) and now downloading Spotify premium offline playlists, battery is at 66%, I unplugged it probably around 9am :)

WiFi on

GPS on

Live wallpaper

Automatic screen brightness

Full volume

WCDMA/GSM

Background data

Calendar Widget

Half-height Weather/Clock widget

E-Mail widget

Twitter widget

Numerous background apps.

Bear in mind that everyone has different requirements, uses and usage patterns. I do more with mine than what I bought the phone to do, far far more, and it still lasts more than a day per charge.

Hy guys, I'm not sure this is a goot thread for posting this, but here goes:..

how's your battery temperature ? I have a battery monitor widget and in about 10 minutes of android.market/internet browsing from 25 27 degrees Celsius it jumps to between 30, 35 and even more.

Is this normal ? It gets hot ...
[Desire General] Tawm:
I can't say anything about the Music app, but I've been using the Spotify app today and my battery hasn't been effected at all really.

Mine usually hovers around 32c, but the battery will get warmer with use, and actually the warmer it gets the more quickly the battery will drain
