I've heard some people say they get 3 days out of their desires and others saying they get just over a day.
This thread it would be great to collect a list of people with desires and their average battery life as well as a list of apps they have installed and widgets on display and maybe the rom they are using.
Just trying to work out
I'm going to collect data and put something up tomorrow - but I noticed last night that my battery went down really quickly when my Alarm went off (using Gentle Alarm) I also confirmed this using JuicePlotter which showed the battery sharply decrease just at the same time in which my alarm was set to go off.
I also noticed that having wifi turned on didnt seem to effect battery life that much...
Yeah my battery lasts really well leaving WI-FI on too. Not sure why others have an issue with it.
My battery will last a day tops turning on from 7.30 and off again around 12am ish
During day I will use Seemic (on manual update) and use FB on net every now and then.
May occasionally go to the Market for Updates.
I only use mobile Network when I need to so I turn off and on when required.
I will play Word Up and Solitaire for 30 -40 mins a day roughly.
Battery % will vary between 65 - 45 by 6.30 pm
Today it is down to 75% at 2.10pm - although I've not played any games today so far.
I bought an X10 and returned it because the battery wouldn't last even a day despite having all kinds of task-killing crap installed.
Then I bought a Desire and had the same problem - 6, maybe 7 hours of battery.
I found a post on some obscure blog that helped me track down the culprit: there are apps that don't let the device go to sleep completely. I had two of them. And Android (at least the HTCs) have a built-in function to see exactly what those processes are:
From the dialer: *#*#INFO#*#*, choose Battery History from the menu and then Partial Wake Usage. Nothing should have more than a tiny fraction of a bar. But on mine, Grooveshark was using 99%. I uninstalled it, tried again a few hours later and saw that Mikandi was using 99%. I uninstalled that, and now I'm getting more than 24 hours of heavy use.
Some apps just don't behave.
Why would Dialer App have such a high network usage?
It shows up as using a lot of network!

Wouldn't the dialer use the network to call people when you dial?
Thanks for the "cheat code" on the hidden menu. Very interesting.
I can sometimes squeeze 2 days out of my battery. I'll only get a day and a half on this charge though because of lots of txting and facebook use.
I found this menu option in Settings > "accounts & sync" > Background Data. I turned this off and seem to get a little more battery.
Changing the brightness down a bit helps, and i'll set the screen timeout to lower as its at 1 minute now. Plus If I use friend stream instead of the facebook widget then it updates when I want to and doesnt keep active.
Least amount of battery time i've had is a day. I never turn my phone off.
I never get a full day out of mine, maybe 8-10 hours max... I have no idea how some people claim 3 days, I'm not exactly a power user!
Stock ROM (not a provider one, just generic) on T-Mobile UK network
Wi-Fi and GPS off
Widgets: Standard Flip Clock, SMS, FriendStream, Stocks (2hr update), Agenda, News (2hr Update)
Market Programmes: K9 Mail (1Hr e-mail updating), ES File Explorer, Shazam, Voice Search, Pkt Ebay, Tricorder, UK TV Guide, GBCoid
In Standby (screen off), not using web, not calling, not texting, not using apps, I lose around 10% per hour, faster if anything at all is on.
Oddly, despite the very poor (for me anyway) standby life, in call life seems really good, I made a call last night for an hour, where phone was in the orange phase when I started and still hadn't gone red at the end...

I wanted to try turning background data off but sadly the market does not work when you have this turned off (a warning pops up when you try)

True re the dialer. Was thinking network as on net use.
anyone got background data or mobile data turned off?
if so whats your battery life like?
also anyone tried with 3G on and compared to GSM ONLY?

Well the only app that have a bigger bar is Android System... Is this normal?
Settings ; About phone ; Battery ; Battery use and it will tell you when it was last unplugged and what has been using it.
4h 27m
Cell standby - 45%
Phone idle - 45%
Wifi -7%
Android system - 5%
Display - 2%
Obviously you can see from that I've hardly used it. A few texts, checking email periodically. Display brightness is on full, weather update is set to manual. Only have a few apps installed. Main one being data counter widget.
2000kb wifi
780kb cell.
Oh, and SystemPanel, tells me I have 93%.
Switch off 3g when you don't need it,this can nearly double your standby/idle time ,use a 2g-3g toggle if its a pain.
Juice defender with its plotter can give you very useful info on when your phone is using its battery the most.
On idle with 2g 1% per hour is normal, with 3g 2-4 %.
As soon as that screen goes on start thinking 15-20% per hour!
Most smart phones are the same,my x1 ,touch pro all got caned when I first got them,but a bit of experience and a few tweaks later they were doing 3-4 days.
Also flatten it and fully charge it when switched off helps too.
My battery life is pitiful too, im a pretty light user now ive had time to play with the phone for a while but battery will always need to be put on charge by around 10pm when only unplugged around 7am the same day.
I bought up the partial wake usage list and UID followed by a number is using twice the power of Android System.
Does anyone know what the UID is?
My battery life was rubbish until i updated the radio version to 32.37.00.32U_4.06.00.16_2. I am also using MCR3.1
Before my battery life would be fully discharged within 7 hours. Now i have 1day+ Not too sure as i now have a brodit car mount that charges my phone during my commute.

To update, do you need to root your device? I don't want to root mine, but I want to get the best battery life possible.

Stating the obvious, but if you don't use your phone, your battery will last a long time!
Personally I need to use my phone (otherwise why would I have bought it) so have push email running with full Exchange sync 8 till 8, FB & Twitter syncing once an hour, spend a couple of hours a day making calls, connect to WiFi using my iPass account whenever a hotspot is available and spend a lot of time dealing with emails etc.
I put my "less than a day" battery life down to the fact that my screen is on and doing stuff for much of that time.
Of course if I just leave the phone on the desk at the side of me and don't touch it all day, even with push mail and all that sync, if the screen is not turned on much, I get 2 days.
It's the screen that eats the battery. The more it is on, the shorter the time between charges.
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
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!
I'd like your opinion on this. Today I had my phone mostly at silent and the display was off most of the time, I was attending a workshop and pretty much did nothing with the phone. Before starting, it had 100% battery but when I came back it had dropped to 63%.
Not only that, it also used 3MB of B/W today over the cellular network(Using netcounter for this). For the B/W I got 1 e-mail account set to sync contacts and e-mail as the items arrive(Push mail) in HTC Mail. Now until a few minutes ago it was also syncing News, stocks and weather under HTC's default settings.
I have VillainRom with 17_2 baseband, the phone is pretty much new and the battery is calibrated.
Note : I'm mostly talking about a period of 8 hours.
OK I flashed LeeDroid ROM and 30_2 radio. I also tried to re-calibrate the battery, but it seems it was calibrated since after removing the phone from charger, shutting it down and plugging it back in it immediately went green.
Now I got one gmail account which has nothing to sync, one exchange activesync account set to sync as mail arrives(push) as well as contacts, one HTC Facebook account set to sync every 2 hours, weather to sync every 3 hours and that too only of my location(I removed other cities). I also got Nimbuzz running and Wi-Fi sleep policy is set to "never", brightness is automatic. Hopefully this'll keep my battery happy.
Lets see how it goes, I plugged it out 1 hour ago(It was at 100%), now it is at 92% although I believe the 90-100% span is kind of delicate and runs out quickly. Not to mention that I also browsed for a few minutes.
Totally agree on the randomness of the battery even when charged. Some days I have a wifi surf whilst having my morning poo for 5 mins and I'm down to low 90's/high 80's. Today I'm still on 99%. My poo lengths don't change much so something flaky is going on.

Heh, I know what you mean.
Its been a bit more than 4 hours and I've had a few calls, browsed the web a bit and read 5 mails and send/received 4 texts. Nimbuzz has been on constantly along with the Wi-Fi and I'm having 82% battery. Seems OK considering the usage.
I know you guys might be tired of these threads but I thought I might as well post this.
My desire is fairly new(Less than a week) and so far its been good apart from(What I though) battery life. i've been trying to improve it and I think I might have "some" progress.
Currently I'm running DeFrost 4.9 with HAVS @ 1137(4.9a) kernel with the very latest radio, I also use only 2G networks(No 3G here). I got two Gmail accounts but only one has sync(The other one is merely for Google checkout CC purchases), I got one Facebook account set to sync every hour as well as LP Facebook widget also set to sync every hour. I also got FancyWidget syncing weather every 3 hours. Apart from these I got Nimbuzz running 24/7 in background. The battery is calibrated and yesterday I did a complete discharge/recharge.
Now I plugged it off the charger 2 hours ago, it was at 100 according to spare parts. The brightness is at 2%. I did some lite browsing, browsed a bit with Tapatalk Pro and 40 minutes ago went to a market nearby. During my trip to market I had Google Navigation turned on navigating me(During both, the trip to the market and return). Now while making this post the battery is at 81%. Does it sound right?

How much time the display was on? How much time was the GPS on?
Be careful, don't be happy before time. I did the recalibration too, and found that my phone would turn itself off at ~20% remaining battery.

During the navigation, about 5 minutes for display, 40 minutes GPS during which I went into a building for 10 minutes and it probably lost signal then.

OK, this ain't good. I slept at around 2 AM with 29% battery life. In the morning(10:30 AM) it was dead(0% battery).

Sound about right. 8.5 hours with your facebook and other syncs. I don't see any problems at all. Mine does this too.

First, in the night put the phone in airplane mode (I dont think u need to check ur facebook )
Second, check if u have useless programs that are using cpu in background, if is this the case UNINSTALL that program and CONTACT the developer. We dont need to kill those kinds of app, we just have to UNINSTALL if an app doesn't work properly, untill the developer will fix it. If all people will do like me, the market will full of great apps
I don't think I have any useless stuff running in the background. All I got are 2 widgets(Facebook and Twitter) syncing every 1 hour and 3 hours respectively, one Fancy Widget fetching weather and Gmail push for one account. Is their a way I can check all the services running in the BG?
EDIT : Forgot to mention Nimbuzz running 24/7.

I won't rehash all of what has been heavily discussed by now in much greater depth, like in the FroYo Battery Usage thread. But auto sync with such social applications and you set yourself up for low battery runtime to begin with. Especially with a constant polling IM and/or battery widget running too. Don't expect much.
Anyway, I don't use them but weather, stocks, 5 mail accounts and news is set to auto-sync every 15 minutes and WiFi is always running if available. Last discharge as soon as I connected charger ended at:
http://bit.ly/c6R59G
http://bit.ly/bmM9oN
http://bit.ly/cMlnun
http://bit.ly/akPvr7
I slept twice for 7-8 hours each on that charge and it includes all of my daily usage including listening to 127 minutes of MP3 via headphones with the screen off.

Hmm Wi-Fi + Nimbuzz really screws up the battery . Last night I turned off the Wi-Fi and slept for 8 hours. I had 46% battery before and in the morning I had 40%. I also have disabled Auto-sync for Twitter/Facebook widget and Facebook app. Now the only running services I got are Gmail push, FancyWidget weather and Nimbuzz.

How did you manage to get such good battery life? Your phone lasted for over a 32 hours period which included 6 hours of display. And that too with stocks and News syncing every 15 minutes. Does Nimbuzz really screw you that much?

Well now datz some good battery. Which ROM are you using? Which Radio are you using?
I don't have any account/social networking syncing. Don't use wifi more than 20 mins a day. Brightness 20%. NO GPS. No Bluetooth. No stupid application sucking battery's power. If my screen is off I lose about 3-4% for a period of 5 hours, so no app sucking the battery in the sleep mode.
If i use EDGE when the battery is Full for about an hour I get battery drain of 20%
Would love to know more details on which ROM, Radio and your settings.
OK. There's not much I can say except what other guys who know better than me said here http://forum.xda-developers.com/showthread.php?t=743172
It's all usage/config/settings dependent. There's no secret sauce. Some setups and usages last shorter than others, yet further, some drastically shorter.
Firstly, I don't change something working well nor move from a setup until I've worked with it the best I could. The ROM I use daily is HTC 2.2 with root. The radio is some old one that worked perfect for me: 32.43.00.32U_5.09.00.20. I can give you some details so you can characterize the battery performance on mine better.
- H.264 sub 2.5Mbps 800*480 video playback at 18% brightness lasts 5.5-6.5h with about 15% remaining. This has been repeated more than 50 times since March.
- My average runtime used to be 13-18h since March but I knew something was wrong and drawing more juice than necessary. I kept looking (mainly at the logs). It took me months to figure out it was a few things including my build.prop WiFi/cell settings, A2SD+, my GMail install, battery widgets, eBuddy, Titanium Backup, Chrome2Phone, Pure Calendar/Grid widgets and my 3G baseband reception. Some app versions were buggy and constantly polling and returning random errors in the background. I had to eliminate them one by one.
I rectified such problems entirely and removed all the unnecessary apps installed which I rarely used. I had to revert back to FroYos A2SD with the install location mod. That took me to todays battery runtime which I'm very happy with. Chrome2Phone for instance could stay installed and be disconnected when not in use to avoid the large background drain it caused.
- I run personalized colour calibration with lowered overall luminance but more red and green with less blue sub-pixel luminance. Very near D6500 whites. I also keep most apps and my homescreens dark when and where possible. I disable button LEDs through a widget when not required (much).
- 24-39h is the norm for me in typical usage. Among much else that always includes a few short calls, some YouTube, some StreetView, some TapeMachine (audio record), some Scan2PDF, some Aldiko, some Chrome2Phone and Fox2Phone, some Tapatalk browsing, some XDA app browsing, some Quick App Clean Cache, some SpringPad, some Adobe PDF, max 15mins of MP3 playback, heavy net and NewsRoom browsing, 150-250 emails and messages and constant sync with what I listed priorly. Always 2G though, and whenever I reach areas I know have bad or no reception (causing high drain) that I'll be staying at for more than 10mins, I disable cell (frequently). I've nurtured the habit of putting the phone in standby after every use too.
- 6-9.5h display on aggregate is the norm for me. I use lowest brightness possible or 18% typically. 50% in very bright, direct summer sunlight. Just now the battery ran out after 26 hours with 9.2h display on, 13.5h cell on and 22h WiFi on.
- I have apps I consider junk removed: Facebook, Footprints, etc. The lot. So no sync or auto running for them or their widgets in the background. I also removed the base GMail because logs showed me it carried on running sync all the time even when not set to. I forced the latest GMail APK in and it has no such problems. I removed all battery widgets installed except one since they drain heavily.
- Heavy usage like GPS, lengthy calls, video recording and playback cuts the runtime down drastically which should be conspicuous. I can drain the battery fully in 5h with everything max and running.

Thats some damn battery life you have there. You are on a Sense ROM? Do you actually use Sense? If so you're either exaggerating or I'm a total fool(I'd prefer the latter).
I've been trying to fine tune the battery, currently I'm using DeFroST 4.9 with SVS 998Mhz @ 1275mv kernel with 17_2 radio. Re-calibrated the battery yesterday and compiled a custom wi-fi module containing fixes for sleep disconnection today morning.
I left it at night around 3 AM with 99% battery, turned off the Wi-Fi/EDGE but kept mobile on. In the morning(Around 9:30AM) I was at around 91%. Gave it a quick charge to 100 till around 11:15 AM. Disconnected it and from 11:20 to about 11:40/45 AM I had quite a heavy chat session over Nimbuzz with my friend. My battery went from 100 to 94% in that time. After that I pretty much left it, picked it up to check a mail once or twice and sent a few messages over Nimbuzz. It is 1:40AM now and I'm down to 89%. All of this was over Wi-Fi, GPS off, Bluetooth off, no tethering no nothing. I got no Facebook/Twitter auto-sync. Only FancyWidget(every 3 hours) and Gmail Push. Brightness is at 2%(Although even then it is a bit bright, maybe it is just me).
I am using Extended control widget to see the power percentage.

It's all usage/config/settings dependent. There's no secret sauce. Some setups and usages last shorter than others, yet further, some drastically shorter.
Firstly, I don't change something working well nor move from a setup until I've worked with it the best I could. The ROM I use daily is HTC 2.2 with root. The radio is some old one that worked perfect for me: 32.43.00.32U_5.09.00.20. I can give you some details so you can characterize the battery performance on mine better.
- H.264 sub 2.5Mbps 800*480 video playback at 18% brightness lasts 5.5-6.5h with about 15% remaining. This has been repeated more than 50 times since March.
- My average runtime used to be 13-18h since March but I knew something was wrong and drawing more juice than necessary. I kept looking (mainly at the logs). It took me months to figure out it was a few things including my build.prop WiFi/cell settings, A2SD+, my GMail install, battery widgets, eBuddy, Titanium Backup, Chrome2Phone, Pure Calendar/Grid widgets and my 3G baseband reception. Some app versions were buggy and constantly polling and returning random errors in the background. I had to eliminate them one by one.
I rectified such problems entirely and removed all the unnecessary apps installed which I rarely used. I had to revert back to FroYos A2SD with the install location mod. That took me to todays battery runtime which I'm very happy with. Chrome2Phone for instance could stay installed and be disconnected when not in use to avoid the large background drain it caused.
- I run personalized colour calibration with lowered overall luminance but more red and green with less blue sub-pixel luminance. Very near D6500 whites. I also keep most apps and my homescreens dark when and where possible. I disable button LEDs through a widget when not required (much).
- 24-39h is the norm for me in typical usage. Among much else that always includes a few short calls, some YouTube, some StreetView, some TapeMachine (audio record), some Scan2PDF, some Aldiko, some Chrome2Phone and Fox2Phone, some Tapatalk browsing, some XDA app browsing, some Quick App Clean Cache, some SpringPad, some Adobe PDF, max 15mins of MP3 playback, heavy net and NewsRoom browsing, 150-250 emails and messages and constant sync with what I listed priorly. Always 2G though, and whenever I reach areas I know have bad or no reception (causing high drain) that I'll be staying at for more than 10mins, I disable cell (frequently). I've nurtured the habit of putting the phone in standby after every use too.
- 6-9.5h display on aggregate is the norm for me. I use lowest brightness possible or 18% typically. 50% in very bright, direct summer sunlight. Just now the battery ran out after 26 hours with 9.2h display on, 13.5h cell on and 22h WiFi on.
- I have apps I consider junk removed: Facebook, Footprints, etc. The lot. So no sync or auto running for them or their widgets in the background. I also removed the base GMail because logs showed me it carried on running sync all the time even when not set to. I forced the latest GMail APK in and it has no such problems. I removed all battery widgets installed except one since they drain heavily.
- Heavy usage like GPS, lengthy calls, video recording and playback cuts the runtime down drastically which should be conspicuous. I can drain the battery fully in 5h with everything max and running.

Whoa ! Amazing post there. This should keep me occupied for quite some time to figure out what the heck is going on with my battery. The battery life what you are getting is really good and that is what everybody should get provided they figure out what the heck is sucking their battery that bad. Lotsa things and apps you have said drains the battery is on my phone and I haven't even started looking at logs in detail. Itz been only couple of weeks since I have this phone so I'll defn start looking into this issue.
Few questions
1. What issues did you have with your build.prop?
2. What battery widget are your currently using ?
3. You have mentioned A2SD+ also is a battery drain, was it a particular ROM's implementation of A2SD+ or older version of A2SD+ or A2SD+ in general causes battery drain ? Would be great if you could link us to the location mod
OK, It is 7:05 PM now and I am down to 70%. Nimbuzz was on all the time along with Wi-Fi(Although I don't know what happened but it switched to EDGE as if it lost Wi-Fi connectivity, Wi-Fi wasn't disabled, just disconnected). And I pretty much haven't touched it since 1:40 PM. Not as good as I hoped, but still kind of decent.
And my Wi-Fi strength isn't that great either, it is either 1 or 2 bar out of 4.
Well, I haven't done any such kernel modifications intentionally. Never had any need to either. 14.5h since last charge now, cell on 5h, WiFi on 12.5h, display on 2h and 76% remaining (actually, those stats were collected and written an hour back). The Desire display has been verified to consume at least 70% of the total device power when the screen is on. So you can't get more hours with display on if it didn't run as such.
It's HTCs ROM so of course it is using Sense. I can't do without most HTC added goods in Sense. Let alone the Mail, Bookmarks, Calendar, Stocks, Copy/Paste, Lookup, Clock, Gallery and Camera apps and widgets. The widgets I depend on work well only on the HTC ROMs I've tried. The missed Sense goodness combined with the bugs and problems I had on AOSP ROMs were extremely problematic so I moved back. Even my video recording and native playback is much better on this ROM.
To be frank, you've hardly had the phone so you'll learn much more yet. And it comes through search->reading->experimenting first. 1-2 weeks is too little for even figuring out most of the basics, unless you're moving from a similar phone and OS. For one, you'll need to actually read the linked thread to see what many observed and experienced. It took me and many others 6 months to learn things and get to this stage. Every other day I was testing and monitoring. But be aware that you can't, for instance, have the exact same setup and usage as me to have the same resultant battery life.
Had you read the linked thread you'd also be aware by now that bugs were filed for inaccurate % readings by Androids Battery Usage section. However, its time tracking was reliable in my testing.
- On your typical full discharge, how much time and % is listed under Display on?
- And for cell?
- Which A2SD are you using?
- Static wallpaper/color?
- Animation settings?
- Location on?
- Network location errors in logcat?
- Cell network chosen auto or manual?
- Did you mention all the widgets on all homescreens?
- OSMonitor/CurrentWidget values in idle screen on and idle screen off?
I use EC and SwitchPro widgets too but their battery widgets (like you mentioned) are known as ones with high consistent drain. The EC dev also corroborated this in its thread under the Themes section.
The 'idle' drops you get don't make sense to me unless there's fundamental hardware/software activity you haven't properly monitored and logged. Even kernel and I/O usage in the background. You'd be surprised at the difference one buggy underlying feature can make.

If you're actually asking those questions, here goes. Note, I am at 66% and the time is 8:56PM. And after this I'm gonna nandroid this ROM and try SuperVillainHD just for the kicks. Also, can it be that since the phone is relatively new, the battery is not up to its full potential?
Q1, 2) Battery usage is :
Display: 35% (35m 37s)
Wi-Fi: 20% (9h 44m 22s)
Cell standby : 15% (9h 44m 22s)
Phone idle: 14% (9h 9m 42s)
Android system: 6% (CPU Total: 9m 35s, CPU Foreground: 27s, Data sent: 7.82KB, Date received: 11.38KB)
Nimbuzz: 4% (CPU Total: 6m 46s, CPU Foreground: 2m 54s, Data sent: 298KB, Data received: 851KB)
Android OS: 3% (4m 1s)
Voice calls: 2% (45s)
Q3) I'm using DeFroST ROM with A2SD+
Q4) Yes, I'm using a static wallpaper
Q5) Animations is set to : All animations
Q6) GPS is disabled, if that is what you mean.
Q7) How can I check this and what would it show?
Q8) Didn't touch this, so I'm presuming Auto.
Q9) I'm not sure, so here goes. I got a Twitter widget, Facebook widget, both are set for manual syncing. Got FancyWidget syncing every 3 hours and several harmless icons. I got 3 bars of Extended Control widget and a google search widget
Q10) I don't have those, are they available in market? Do they consume battery?

I'll have to open the file for that to check exactly the changes I made. I didn't really follow anyone, just went off my own understanding and intuition. If I try to access the dir or open the file whilst the phone is not in Recovery, it'll force a reboot so I'll give more details later on this when I'm near a PC.

FroYos A2SD was nice but I needed much more space and was trying A2SD+ with various ROMs as well as manual use on HTC ROMs. Endless problems such as very remarked, consistent sluggishness in basic functioning, total boot and app load slowness, including high, persistent background CPU and IO loads and very poor SD card transfers over USB and WiFi made me sack it. I lost a class 4 16GB Kingston SD card with errors inside 2 months. I transfer 2-4GB in/out daily and many transfers started failing. Widgets bugged out frequently when you needed them most and had to be all re-setup. Video record and playback became dis-able. The phone became useless except as a toy. That's not what I bought it for but as a helpful companion. I eliminated everything in question. It was simply the SD card [over]use compared to internal memory.

I simply typed the command through adb but:

http://forum.xda-developers.com/showthread.php?t=778738
Even though I used this, I still have select applications not on the SD card upon learning that they worked far more consistently and properly with lower power and CPU usage when using internal memory. Trial, observant monitoring, and error.

- HTC Desire via XDA App -
I installed the new app yesterday. Its nice to have a options menu again, I set update to never so when I close the app I expected it to fully close but I am left with 3 apps running for Facebook. I left my phone unplugged last night when I went to sleep and my battery went down 12% whilst I slept. Normally only looses about 2-3% in this time. Only app has changed is Facebook so it must be this. Anyone else having this issue?

Same Herr! I only lost 10% but i think this depends ob Thema length offen my night (only 7 hours) and in Thema fact that i'm switching permenantly all my connections off

yes, somehow with the new update, if we press home, the total cpu time will continue going up and eat my battery a lot probably 5% idle per hr wifi sync on.
Then i decided to swipe it away in the multitasking menu, and it stops, battery back to my normal 0.5 - 1% idle per hr wifi on and sync on and whatsapp on. So u can try that. hope that helps.
Glad it's not just me. But I thought I would do some extra testing.
When I first got my Nexus, coming from a rooted CM'd Desire, I was amazed the battery went down only a few percent over night and I've been getting over a day of use with it easily even when using the phone frequently. After an average day I was on 30-45% battery. I even tested with Skype on wifi, then left it on 3G and I still got good battery.
The day after fb install, I barely got through the day. 12% is what I ended up on. I'll test for a few more days.
Hi, how its your average batery life?
I have never really run any tests for it, but i've left the tablet alone for a few days, just sometimes checking for Firmware updates, and it barely lost 30% (maybe less, can't recall).
with no live wallpapers on mine lasts a few days with moderate use (checking email, rss, news, maybe playing a couple games)
Well i got the Archos 80 G9 250 gb version and mine lasted for 4.5 hours of continuous video playing , screen brightness on 50 % . The problem is that even in deep sleep it looses battery . How can it last for a couple of days i can't understand , any hint ?
I have the flash version, maybe that would make a difference. Check the wifi sleep policy, and make sure it turns off during sleep. Also, I keep bluetooth and gps off. perhaps try that?
I have the basic 80 g9 and for just using it the evenings it will be happy to last for 4/5 days with email, twitter simple games etc. When I've travelled with it in 3 hours of video playback I lose about 50% with no connections such as WiFi or 3g.

In the meantime you close the tablet or put it on deep sleep ?
I just hit the power button and leave it. Like I say don't think I've messed with the deep slept setting but can look for ya later if you want.
Sent from my R800i using XDA App
Well actually i didn't checked that but i have the impression that mine looses a lot of battery in suspend mode .... I always shut it down and even like this when i start it again its not the same as it was .... maybe the actual starting process uses a lot of power don't know
Could be a rogue app. My phone was like that for ages and it was getjar nit letting the phone sleep properly. Try better battery stats or something similar to see if a service is causing partial or kernel weaklocks too frequently

The 80G9 1.5 GHz turbo I just started using is to new for me to get an idea of run time, so far about 8 hours of mixed use, on my 8gb classic would go between 5.5 to 9 hours depending on use, in deep sleep non use, it would go for days at least
What works for me, on best battery management, I like to put into deep sleep every time I put tablet down and plan not to use for a few minutes or more (this turns of Wi-Fi, screen, and stops mosts things from running) it always wakes up with a quick power press and Wi-Fi connects within a few seconds
I use normal sleep (same as when it times out I think) for quick pauses in use.
normal sleep for when not using but charging if I want to hear notifications for email, Color Note, Evernote etc. (Wi-Fi on)
If I want the quickest charge, (not using, overnight etc.) and I don't care about notifications (Wi-Fi off) I use deep sleep. edit, to be clear on notifications, my Color Note notifications work while in deep sleep
Turn off for longer periods not being charged/ used
You can set when Wi-Fi disconnects by going to:
settings, Wi-Fi, Wi-Fi disconnect policy (I have mine on never for now)
*and of course, use the correct cable and charger!
