Instant battery drop ?

After being on the charger after 7 hours as soon as I take out of the charge my battery his down to 98%. I made one phone call of 2 min and 3 txt messages and it dropped another 1 percent. Before this charge I let it fully drain. Anyone?

I experience the same results - When the phone is powered off and on the charger, it only goes to 98% (according to the settings-->about phone-->Status-->battery level
However, if you turn the phone on, and charge, it will reach 100%..

this is insane... my bat is down to 93% and since the first post to now i haven't even USED the phone... i think my phone is not going into full sleep whatsoever. I uninstalled 3g watchdog yesterday as some people mentioned in other forums that sometimes it wouldn't let the phone go into sleep mode. No kidding... that i only noticed this dramatic change in battery time after i installed LauncherPro. when i was using touchwiz on my second charge the phone lasted a full day with moderate use and i didn't even drain the whole battery. Yesterday was the first day i left the battery to die, i had this phone since last friday.

I was experiencing excessive battery use when I was running LauncherPro. I switched to ADW.Launcher and it went away. I also use JuiceDefender to manage connections while the screen is off. It disables data connections and turns them on for 1 minute every 15 minutes to update any data streams & then turns the data connection back off. I can get around 14 hours of light to moderate use now.

to check if your phone is properly sleeping
Plug into charger
Unplug and hit power to turn screen off
wait 5 minutes
hit power to turn screen back on
using spare parts or any other application which shows battery history(battery leftwidget)
check: Running%
It should be less than 10% for someone with a ton of background apps or widgets
It should be less than 5% for someone without a ton of widgets/bg apps
During normal usage it should be within 10% of the screen on %
Exception to this is if using something like music player

100% !!!!! I installed awd bedore doing this test and had no widgets running whatsoever

Again with the Battery

Is anyone that is having battery issues running Adao Task Manager and Battery Status Pro?
I just factory reset my phone and I got 24hours of batter life. About 8 standby but a good deal of texting, web, some calls and some you tube.
I installed Task Manager and Batter Status Pro last night and my battery this morning went down 15% in about 1hr.
I uninstalled these today and will post again but has anyone else seen big battery drain from these apps or does anyone that is having issues running something similar?

I have been playing with the battery for about a week now.
For me this phone runs pretty good during stand-by. I would have about 2-3% drop for a whole night (7 to 8 hrs), with Google (push), Twitter and weather syncing.
The problem is when you use it, it drops like crazy. When I read news or surf the web, it would drop 1% every 1 or 2 min.
This morning I read an ebook, with black background for about 30 min, it dropped about 3%.
So basically i think the screen, data connection, and non-black background are the ones that kill the battery.

Yea, I agree, the S-AMOLED screen in this thing is an energy hog. OLED's are supposed to be more energy efficient than typical LCD's but I'm just not seeing it. Whenever I look at battery usage stats it shows the display at 70-75% of battery usage. Thats ridiculous. I have until the 18th, but I'm quickly leaning towards returning this and just getting an iphone4. This phone is becoming more and more disappointing the longer I have it.

This morning I have been uplugged 4.75hrs and used 16% no battery monitor and no app killer. Basically done the same things I did yesterday. Some Bebbled,texting, email, phone calls .
I will update tomorrow with total hours battery life for today. Would be happy if I can replicate the 24hours I got the day before installing those apps.

I got like 45 hours of battery with moderate usage during the two days. Seems fine to me, I occasionally used system panel to monitor if anything was using high and constant CPU

This is pretty typical of a 1ghz phone My nexus would last a day of heavy usage, 2 days if i use it lightly. We need to wait for undervolted kernels to be developed xD
Also, it really helps if you disable 3G when you don't use it. This allows me to get 3-4 days of light usage out of my nexus. I haven't played with the Captivate long enough to know how much of a difference this makes on this phone though

when you guys refer to "stand by", what exactly do you mean? Just screen off/phone idle? The battery usage on my phone when I use it seems to be OK even if not amazing, but it continues to sap life from the battery when I'm using it at an alarming rate.

Standby is when the phone is idle/screen off/locked.
The display is definitely power hungry. Using the Power Control widget that comes installed definitely has helped with battery life. It will let you toggle WiFi, BT, GPS, Data Sync, and Brightness (at 3 levels). When I'm not using anyone of those, I turn it off. When I'm indoors, I'll set the brightness to the lowest level. I'm usually at my desk when I'm streaming music, so I'll have it plugged in.

Actually they are more energy efficient on black screens, But screens with a lot of white in them suck battery bad.

This is true the white screens burn the battery etc. I just wanted to let everyone know what I did to make my battery last more that 24hrs.
First, read the Wiki guide and apply some of the battery saving tips.
Second, UNINSTALL a program called "gReader" created by noinnion. This program is a huge battery hog! At least it was for me.
Hope this helps.

Well I guess I am one of the "lucky ones" Im running a live wallpaper and have not run my battery down since the 1st day. Right now Im at 40% life and at 15 Hrs 30m since unplugged. This is with checking facebook, twitter, email, phone calls, internet browsing\video watching and following the steps for the GPS fix. The only thing I have done is install ATK on the phone, besides that its all stock.
One thing I know is a huge battery drain is Time without Service. Check that stat and see if you have anytime at all without service, if so, I am pointing to that as a major drain on the battery. I know currently I have 0% Time without signal, my fiancee however is usually in the 20+% range and her battery drains like many reports I have seen here (she has an EVO).....

Yesterday I only managed 16 hours. Web, Email, A bluetooth file transfer, short bit of gaming. I have about 5% of the cell standby time (26%) without signal. My girlfriend has the Aria which is running Android 2.1 also, has all sorts of widgets, haptic feedback on and can make it at least 24 hours. I get that it has a smaller screen but it is also an LCD. Shouldn't the Super Amoled be saving our battery some display consumption.

i get about 14 hours or so moderate usage and at the end of the day, i have about 35% left at night.

If you detail the "Display" usage in the battery usage details how many minutes has your screen been on? Mine says 1hour 2mins ...this is for 8 hours of running time. My display is using 50% of the battery (which is at 68% now).

W00t W00t today I have reached a new high 2 Days 6 hours and 29 minuts with 12% battery left.....

What I have found is keeping Wifi on while I am at work and home like almost doubled my battery life. Which is great that I can use Wifi all day and not drain the battery so fast like my Fuze. Right now been off charger since 7:30am and I have 84% left. Yesterday after 9 hours I was still over 50%. For me its better than any other smartphone I have owened.
I used manual brightness, (swipe notification bar), turn off GPS/BT. black wallpaper and set Wifi to never sleep. Also the power saving mode in settings is off for other reason and doesn't affect battery.

At 18% right now and it's been off the charger for about 30 hours. I noticed yesterday that while I was connected to wifi at home (with Y5 app), it was draining faster than when I was connected to 3g. Did some tested back and forth and JuicePlotter clearly had a noticeably steeper downward slope for when wifi was connected than when it was using 3g. Weird :\

battery life

anyone feel as if their battery life sucks? I do have 4g on at all times but I didnt think it would make that big of a difference in terms of battery life.

See my post here:

Try installing a monitoring app and see if your init process is hitting the CPU hard. I haven't heard from any other mt4g users with the same problem, but lots of.desirehd users have it.
I also have seen my suspend process eating 50%+ CPU when the phone is locked/screen off. Haven't found a fix for that yet though.

I'm getting a full 24 hours of heavy texting, moderate phone calls. Battery life is better than my magic... im having no issues.

Yes, I woke up this morning and my phone was already blinking and battery is on 8%. I left it overnight with more then 60%
A big problem also is that SetCpu cannot force the scale. If limit to 768 Mhz it still scale to 1024. So not I am sure that my ScreenOff profile with 245 Mhz DOESN'T WORK!
THAT'S SUX!!!

Weird I leave my phone at full overnight and its still at full when I wake up.

Try disabling the preflock that might help before I did that it wasnt scaling properly now afterwards it is.

I have frozen a few apps and use advanced task killer every time i start up 9a lot of apps come on at start-up).
The result is pretty good battery life. I have only gone dead when I had a few apps (like GPS navigation) running in background and forgot about them.

I'm having 0 issues with my battery. It easily beats out the battery life on the Samsung Vibrant I had.

I'm having issues too. My battery life today was 40% at 1 PM, and when I left this morning, it was full. I hardly even used the phone except to check email :/ I have brightness on auto and wifi off. Not sure what the issue is.

My battery life has been really good. A typical cycle is charge to full and disconnect power at 10:00 pm. Up at 6:00 AM, battery is still on 100%. Today my use has been moderate to heavy. It's now 2:30 PM and I have 68% left. I typically have around 30 percent left when I put in back on the charger. I'm happy with that.
Wifi, Bluetooth, GPS, etc., are kept off until I use them. I do however leave Background data and Auto-sync on all the time.

I turned on USB Debugging as recommended and my battery life is much better. Right now it hasn't been charged in 9 hours and is at 79%. I've downloaded 2 apps, updated 3 apps, sent multiple emails, light internet use, and 3-4 calls. I'm unrooted and don't use any task killers.

That's awesome. I'm going to turn on USB Debugging mode and see if I can squeeze a little more juice out of it.

I have had intermittent battery-drain issues too. On Saturday morning my battery went from 100 down to 76% in a matter of an hour or two with hardly any use. I did a restart and it seemed better. I've also gotten into the habit of restarting my phone once a day, right before I take it off the charger in the morning. I've turned off quick boot, which I read somewhere in the forums can affect battery life. It's been pretty good the last few days. I'm at 68% now off charger for 9.5 hrs with moderate amounts of wifi, web browsing, email, and 3G network usage. I'm new to android devices so I don't have much to compare that to, but it's working for my schedule.

heavy user - fully charged phone at 7am ... start using after 7:30am
check emails, fb, txt, barely to no calls.....phone will be down to about 20% at 1:30~2pm....
yes the battery is lame...but this is a known issue with HTC...the 3.8 screen drains a lot of battery also the constantly searching for HSPA+ and 3G...
I do notice when screen is off....this phone still drains battery !!! bad =(
left over night at about 65% left in the morning I got red blinking led saying phone is below 10% .... 50% gone!!!
I think restarting the phone after a full charge is a good idea....also maybe turn off quick boot?
*update* yes I found that when you have a bad signal and it's jumping between E and H ... this eats up battery
also installed Advance Task Killer (for froyo) this helps~ now from 8am my phone can last until about 4pm getting about 3~3.5hrs more life

Mine lasts all day with everything on, playing games, email, text, etc, etc.
It is great, best phone I have had. Not sure what the issue is unless it is root.

It depends where you live.
If you get a good antenna signal, your battery will last.
At my apartment signal is low, so phone is constantly between UMTS and GPRS, plus phone is trying to hold H, so that drains the battery.
My signal strength parameters:
between -101 dBm and -107 dBm (where -110dBm is the edge of the signal/loosing signal)
3 asu and 7 asu

Good battery life thread

I've been sitting at 69% battery for the past hour and 48 minutes.

I've been using the phone for about 18 hours, and I am at 45%, ill post some pictures in morning, going to bed.
Sent from my LG-P999 using XDA App

it's been 1d, 10hr, 59min,
and I'm at 57%.
but of course very mild use:
about 30min of phone call,
25min of web browsing,
13min of XDA Prem
20min of music.
20min of clicking around randomly in the phone
I am a "minimist". I only run apps when I need them so I have pretty much nothing running in the background (except Google Voice). I don't even have a widget, only 1 screen of shortcuts. so put that into consideration before comparing your battery life to mine. I am just giving an insight about how I achieved mine.
Removed(deleted) all bloatwares (wifi calling, myaccount, lg.omadmclient)
Using Titanium Backup PRO, froze several apps (which I don't think matters, since I never see these apps running in the background anyways)
Using StartUp (the program), I disable A ****LOAD of things, so apps won't startup by itself due to whatever reason
did the HTC battery conditioning twice, then wiped battery stats
has a SetCPU screen off profile of 216/216.
no apps that sync at all (except Google Voice, which is constantly running)
default brightness
use ATK to kill tasks manually everytime I'm done using the phone, before I lock my screen (NO AUTOKILLING)
what I've come to realize is that no matter what u do, when you use the phone, the battery is going to drain. when my screen is off/idle, i lose almost no battery. For example, the day before yesterday, I lost 3% battery overnight (8 hours). Last night I lost 1% overnight (8 hours). But when I actually use the phone (screen on), i lose battery fast.

My battery life was awful the first few days but after uninstalling the capacitive buttons led notification app and calibrating my battery it got a lot better. It now lasts me the entire day with around 30% left when i plug it back in. I do turn off 4g when I'm at work and in a few of my classes because I dont get good reception.
The battery seems to last a really long time on idle but as soon as I play a game (guerilla bob thd) the battery drops about 10% in about 20mins (while im playing) and then goes back to about 5% an hour

Here's my battery life... http://forum.xda-developers.com/showpost.php?p=13438062&postcount=21

Haven't tried to stretch my battery past what I needed yet but I used it for 1 hour 2 minutes straight today and only lost 10% battery. No way thats happening on my old phone. Used to lose 1% every couple minutes the screen was on.

That's how much I'm losing.. the phone is pretty good when it's off.. when there's no network.. but I went from 65% to 45% in 1 hour, and that's just from texting, really not liking that.

Damn that sucks. I only lose 4-5% per hour of left idle. Something is prolly up with your phone.

You lose 4% - 5% when your idle? That's how much I lose when I'm idle, probably even less.
When I touch the phone, it starts to die really quickly

Dunno whats causing that. I drain pretty slow during actual usage. My screen brightness is usually 25-30 that prolly helps a lot.

Damn, same here man, what about GO SMS or Go launcher?
Does that kill battery?
I removed Go launcher, I really loved the look, but testing if that kills the battery?

I use both and have never experienced them using any more battery than any other launcher on either of my phones.

no deep sleep and mediocre battery life?

Hi
I have the phone since this weekend, and I am not seeing the ultra great battery life that reviews had.
1% per hour while not using the phone and 0% of that time on deep sleep?
25% lost with just 40 minutes of screen with very light use?
70mah of use for using the camera to record a single video of 30 seconds? wth?
any idea?

You can hardly charge the battery life after only one or two days owning the device, it needs time to settle down.
If you do have something draining your battery, its a rouge app.

I also experienced bad battery life at first but later on found out it was due to 5G connection. Maybe you will find reason for your case soon.

I had your problem, I rebooted the phone (just reboot) and the deep sleep worked again ,these are my consumptions now, only wifi, camera, youtube, games (heavy use) the application closed in deep sleep and I do not capture my sleep hours, 10 hours approximately
