Battery drain with Desire on alcohol

Hi. I know there are hundreds of threads on battery usage, but I felt I have a special story behind my test.
Lately I feel that my battery life has decreased, but I would like some second opinions on the case.
It's over a month now since I received froyo OTA, and I had some suspicions that my battery life went slightly down after that. I used it more to test the new features, so its hard to really know. However, the big problems occurred a couple of weeks ago.
At a party with a friend of mine, a friends friend literally pulls my Desire out of my hand and drops it into a mug of beer! As a joke!!
He had heard me taking about my Nokia 3720 earlier and decided to test it. However, ignorant as he was, he did not see that it was A DIFFERENT PHONE I was holding!
So it took 2 seconds in the mug, and the screen went black, and the phone was dead... Or not really, I took it out and dried it of with my t-shirt, turned it on, and the screen went garbeled green on me...
Decided that it was best to leave it alone, so I took out the battery, SIM and MicroSD, dried them off, put it in my pocket and continued the party.
But I have to admit it was kindof a partypooper for me...
Well, later that night, probably 3-4 hours later when I got home, I inserted the battery and tried to turn it on.. Screen turned on with the familiar white background, and green htc logo.. and some garbeled green at the top, argh...
I took the battery out again, left all the pieces spread out on the kitchen-counter and went to bed.
The morning after (or should I say afternoon ) I looked at the phone, it seemed as it had dried out over the night. So I put in the MicroSD, SIM and battery, crossed my fingers, and turned it on. And it worked fine, like nothing had happened, phew!
But some days after, I am sure that the batterylife has decreased quite a bit, seems to not hold a normal 12-14hour day with normal use.
I did at one point post-froyo (pre-drowning) have it running for 2 full days before charging, approx. 40 hours, not very much usage though..
So, I decided to test it starting yesterday evening.
I let it drain fully (turned it on 1 time after it died, and let it die again). Charged it while turned off, and unplugged it and turned on after approx. 1 hour of full charge (green light).
Now, I have already ordered a new phone (a Streak is on its way over the North Sea as I write this . But I wanted to do the test just for the heck of it.
My girlfriend also has a Desire running Froyo, and I notice she uses her phone WAY MORE for gaming and stuff, and only charges a little more frequent than me.
They are both AMOLED phones, I got mine in Feb, she bought hers in March.
So, here comes the timeline:
@23:30, Turned it on after fully charged, went through all homescreens to activate all widgets. Did not run any programs.
I have no specially data intense widgets, only email and weather (3hr sync). Wifi off, and 3G (H) on always, no active background.
@08:00, On my way to work, Battery indicator (i use *#*#4636#*#* to check battery status) at 88%, recieved 1 email during the night.
Battery usage says: 49% Cell standby, 49% phone not in use, 2% android system.
I have noticed my phone struggling to keep connections while travelling even short distances(pre- and post-froyo), maybe a little worse of a problem post-froyo.
Did not happen today though!
I often need a reboot to get the connection back (Flightmode often works 1 time, but not 2 times. does not activate the second time I try it, just hangs...)
It's not only the data connection, there is no cell reception at all (apparantly).
Maybe I should start a thread on that also, but it is not a big issue for me (this phone is on a free use data plan, almost never use it for calls)
Dataplan here in norway costs around 50$ btw, no other extra costs for tethering and such in norway
@09:45, at work, recieved 2 more emails. now @84%, on EDGE network. battery usage: 53% Cell standby, 45% phone not in use, 2% android system.
not that bad actually... 10:21 "on" time, with 34 minutes active-use time.
Will try to leave the phone alone some more, and do some surfing on it around noon.
@12:55, still at work, used the phone for surfing and gReader for 25 minutes, on EDGE network. Downloaded a BOL revisited episode (podcast), I usually listen to an episode via bluetooth streaming while driving to/from work.
Now @67% and 35°C ( I noticed an temp. increase). Cell standby 47%, Not in use, 41%, android system 9%, screen 3%. uptime 13:35, waketime 1:07.
It connected to H (3g) the last 5-10 minutes or so of surfing. Turned on Wifi when I was finished, to see if I notice any battery decrease.
@14:25, did another 15-20 minutes of surfing, this time on Wifi, now @62%. also was a quick trip via google maps with gps on. battery usage states: Wifi usage 3% and google maps 2% already.. seems they use a lot of battery in a short time.
Wifi is set to turn off after 15 min of inactivety.
TBC....

Read that. Do a teardown and clean everything, you're out of warranty anyways.
Most likley a drop/smudge of beer etc inside short circuiting something and you'll have a slow, but increased battery drain from that.

thanks for giving me a heads up on that!
Not sure if I will take the time to fix it though, I'll have to see how much I miss it when I start using my Dell Streak

@15:35. On my way home from work. Writing using voice recognition on android. Battery level is currently @ 46%. Downloaded several emails, and 1 reply. Now connecting bluetooth for BOL streaming.

Okay now i'm home, after 40 minutes of Bluetooth streaming battery is @36%. Stats are: cell standby 39%, not in use 34%, android system 15%, screen 5%, WiFi 3%, Bluetooth 2%, maps 2%. Times are: 17:07 total, 2:49 awake.

@18:15 Surfing for 15 minutes now over 3g, and battery icon is orange.. level: 27%, awake time is now just over 3 hours.. I think it has held up quite good today, but I have really not used it as much as I normally would. And I also have a suspicion that using less WiFi helps a little on battery. Previous I have used WiFi always on to save 3g usage, but maybe it decreased battery.. anyone with a comment on that?

[SOLVED][Q] Battery issues?

Wondering if anyone else has had any battery issues? I went to sleep last night with about 85% or more battery, and 5.5 hours later my phone was dead....when i plugged it in for like 5 minutes to call my work and tell them i was going to be late...when i got to work my phone said 45% phone idle and 45% cell standby for battery use

none here - took phone off charger about midnight, this morning after alarm rang for the full 10 minutes, it still showed 100%
i've been watching it and am really impressed with battery life - is it possible you've got a program running in the background? - i had Startup Auditor to stop apps in the background but had that from before, on my Vibrant
on the vibrant,running a predominantly black wallpaper, screen brightness at 13%, putting phone in "airplane mode" when i sleep, keeping GPS off, data sync off etc, it'd be down to 17-22% at end of day before going back on charger
this G2, running live wallpaper (thunderstorm), no efficiency moves (ie GPS off, etc), screen brightness at 50%, phone still had 34% last night before going back on the charger - and the battery has not "conditioned" - i noticed on the past 2 phones batteries life got better after the first few weeks of use.

Nothing different than my nexus...and i was thinking maybe it was a game but that should have been killed automatically and i dont think it would say phone standby and cell idle if it was an app would it?

tonite you might try putting the phone in airplane mode when you go to bed, and turn off GPS
see what happens to battery drain overnite - if it diminishes then i'd look at what apps you've installed. there was an article on engadget not too long ago that some researchers had analyzed the 358 most popular apps, and found 30 were reporting data to their "mothership" that had not declared it or asked for permission to report data.
hope that helps

well another weird thing is, that when i bought the phone and brought it home, usually it comes with half battery and thats what it showed but i had to charge it quick with no apps really installed on it yet...Im charging now and will test to see what happens with battery...i just removed off alot of my apps.... to see whats up

I'm getting about 10 hours with regular usage though I wish I knew why Photobucket keeps starting everytime i kill it.

I hope you guys charged the phone fully before you used it first. That can play a big role in battery life.
I got my phone yesterday and haven't done any calibrations yet. I've been playing with it like you normally would if you buy a new smartphone. I took it off the charger around 9pm last night and at 7:32am right now I have about 60% left. So roughly 10.5 hours later and I've only lost about 40%. I'm very impressed by that. My vibrant would have been dead by now, it rarely lasts through the night if its not on the charger.

What's your time with out signal, sounds like the 50% bug to me, google the airplane mode fix, if not you might want to look into a new radio, and you should allways recal your battery after you flash

Battery Saver Mode Experiences

Hows the battery life you guys are experiencing with the mango update in general with and without battery saver mode on
is battery saver mode making a big difference?
im using battery saver for when the battery gets low and im noticing a bit of a stretch of extra battery life on my htc trophy (verizon)
when u turn battery saver mode on doesnt that disable notifications push and toast?
i know i havent tried the battery saver mode on the whole day to notice any difference just wanted to see if anybody else has yet and what kinda life are u getting on battery saver mode on all the time and when the battery gets low

well for the one day that I left my charger at home by accident when going to school I turned on battery saver mode and was able to make it through the entire day with my normal use habits with about 30% remaining once I got home. this was when I was on 7712 haven't done this on the official yet.

My 7720 experience was pretty horrid with battery life until I got the Samsung update on Tuesday. I went from barely making it 10-12 hours on a charge to 18-24 hours. I can get up to 1.5 hours with battery saver turned on.

For the first couple of days, I left my status set to "online" the entire day, and my battery barely lasted through the day (around 15 hours). Battery saver mode came on after about 13 hours, or it wouldn't have lasted.
Today I set myself to offline, and last time I checked it (after around 8 hours of normal use), it showed 80%. So it seems pretty clear to me that overall, Mango battery life is very good, but keeping yourself online is a killer.

Battery saver mode works pretty well for me... I love it... Thank god its inbuilt and I didn't had to download another one dollar application to do this thing.. Things like this should be inbuilt .. Also adding additional tile shortcuts of any kind we want..

Haven't tried it. Battery life went down noticeably but I have chargers everywhere. I stay online all day. If I wasn't online in message hub I'd be online in some other app so why not. On Android my gtalk is always on as well. Don't see this phone lasting a day for me with or without battery saver, lol.

I'm still debating about staying online all day. Most of the people I chat with on Facebook are online in the evening, but not so much during the day.
But I love the battery saver option. When I was online all day, and it did kick in toward the end of the day, I observed the battery usage drop to a mere trickle (it only lost around 1-2% per hour after that). So, without having to change anything, I can be assured that my phone will still be available in an emergency.

at full charge my venue pro shows me around 3 days and 18 or so hrs...with battery saver i get 3 more added...best part is i play music moderately, use the radio, wifi on all the time and at the days end it stil shows around 2 days and 12 hrs or so time left....is somthing wrong cos when i first bought the phone, 15 hours was the maximum i got for the phone.....

plug in charge usb messenging hub locks up
has anybody had this happen?
when your phone is in battery saver mode and you plug it in it becomes unresponsive and kind of locks up. messages and emails don't send or receive.
only way it ever happens for me:
if i was in a message and i plug into usb computer or wall outlet power the phone cant switch back from a message to the list of messages, i cant send the message that is typed, i cant type, and no messages are received (or show up after a reset) i can go back home but every time i try to do something it says loading and closeshas happened for a year now

Battery life for me in Mango and 8107 (or whatever the latest update is called) has been pretty awful. I recently did a hard reset.
Post hard reset, a full charge would say 1D 4hours or something
After a few weeks, a full charge now says 18 hours, but lasts considerably less.
By noon my phone is at 50%, if I don't charge it, it hits battery saver mode by the time I leave (6pm). That's with taking it off the charger at 7am, and barely using it. Pretty horrible.
I'm seriously considering a BlackBerry. WP is great and all, but it's just not built for business use. And I need a battery that can last more than 10 minutes.

Sounds like you have a bad battery. My titan is at about 72% after an 8 hour day with lots of email use and some browsing / texting through the day. (i check 7 email account and exchange and hotmail are both push) Currently at 10pm mine still says 52% and estimates 10 more hours use. Now if i were to play a game for an hour or more i'd probably kill it but for browsing and more business like use... it can't be beat. My old surround lasts about 16 hours with wifi on unless my wife games it to death.

Geez I wish.
Maybe it is time to switch it out. I've had it since Jan '11.

my 1st GSIII was defective(phone HOT while off)

Just an FYI,
My 1st sprint GSIII was fine for the 1st month. I could get upto 3 1/2 days of battery with very light usage (mostly standby time). NOt sure what caused what happened next but the phone became extremely warm and the battery life dropped to approx. 2 hours. The phone was very warm even while off for hours!! And it obviously got even hotter while on the charger. The only way to get the phone to return to room temp was to pull the battery and leave it out for a few hours. Turning wifi/data/sync/GPS etc. off did nothing. The odd thing was, the battery was a normal temp. The heat came from the lower part of the phone (where the processor is). It also gave incorrect battery readings. While plugged in it would read "100%" and "charging" the LED stayed red, never turning green. I also could pull the battery and put it right back in and it would read 20-30 % difference VS. when I took it out.
The phone was swapped at a sprint store covered by insurance.
The only thing i did differently usage wise was link the phone to my dropbox account. It seemed to sync normally so i can't confirm dropbox caused the issue. I just can't figure out what the phone was "doing" while it was off. Just thought i'd share the story with the phone. The new 1 is running fine.

I found this today. Appears to be helpful with heating up and improved battery life.

This doesn't sound good at all. My cousin's GII on AT&T did something similar to this. The phone would be completely turned off and it would vibrate every 10 minutes. Even pulling out the battery and reinstering it made it automatically turn back on and vibrate again and again.
Hopefully this is an isolated issue what you are talking about.

What kind of signal are you getting?
Mine was like what you descrbed for a couple days(almost no signal at home) and I was getting ready to return it but didnt have time because I was leaving for Vegas. Long story short when I got to Vegas I upated profile and PRL and havent had a problem since. Maybe the towers in your area are under constrction.

My phone has gotten hot ever since I got it, but it will cool down when I stop using it. I am getting horrible battery life even witha 4300 mah battery. today it wouldnt even last 11 hours. It had 3 hours total usage time on it. I am now trying another 4300 mah battery to see if that is the problem or if its the phone. my reg battery wont last me very long either. I am also using juice defender free version and advanced task killer plus the built in task killer and I cannot get my phone to last very long. With my orig Evo I had the sprint extended battery (2500? mah) and it last me til bedtime with 50% left.

The only time this happened to me was when an badly behaving app "ran away". I would get really bad battery usage at the same time. I could cure it by clearing ram, which shut down all the running apps. Since this hasn't happened to me in a while I'm guessing that whatever app was doing that to my phone has been updated to fix the bug.

My issue was very odd. My phone was normal lasting up to 3 days with very light usage. It would sit for hours at "room temp"..the only thing i did differently was link it to my dropbox accnt. It seemed to sync ok..it was shortly after that i noticed the phone was very warm towards the lower 1/3 of the phone. I thought maybe there was something running or taxing the processor. So after working on it for a few days(turning everything off i.e. wifi/gps/data/sync/etc etc.) the battery got worse and worse. I then unlinked dropbox, stopped all running apps and let the phone sit in airplane mode over night. Still no joy. So i turned the phone off and let it sit for about 6 hours. It was still "very warm" while off!! At that point I pulled the battery for about 2 hours and the phone returned to normal temp. What could the phone be doing while turned off for hours?
The phone was stock and updated. I use an airrave so i dont have signal issues. The processor seemed to be running at full load even while the phone was off. The battery life went from around 3 days to not even 2 hours. The phone did seem to have the known "cell standby" issue(where the counter is reporting an incorrect usage %). While charging, the phone was even hotter to the point of me thinking it would burst. Oddly enough, the battery was at a normal temp. It was no where near the temp of the bottom of the phone(where the processor is located).The new GS3 is running normally so far. The tech at the sprint store couldnt figure the old 1 out so they just replaced it(insurance/no charge).

[Q] About the battery life

I got my SW3 few days ago.
When I "unbox" this whist, I just did the init. installation (update) with the 5.0.1 version of Android Wear without fully charge it first.
After few days, I found that the battery lifetime can NEVER exceed 18 hrs from fully charged.
However the specification stated it can be up to 2 days, and some people in other forum posts said it can be more than 2 days.
I would like to ask if it is normal or not? Do I need to replace it? I am very confused.
What are your experiences? Please kindly share.

My watch was full on Wednesday, and I just plugged it in about 45 minutes ago with 5% left. Now, I did have it off overnight last night with about 32% before shutting it down. However, Wednesday night into Thursday I left it on and I only lost about 6%. So even I left it on last night, It would of still lasted me until 5pm today getting home from work. So I can go 3 days with my watch and getting a decent amount of notifications. Screen always on here as well.
I voted >60 because it does last me more than 2.5 days. I'm somewhat careful with it to get that amount, but it's certainly not hard to get that. But it should 100% absolutely be getting more than 18 hours. My suggestion would be to factory reset and only leave the essential apps on there that you need, if any. Just use the watch in it's bare minimal and see how your battery life is. If you still struggle for 18 hours, I'd say swap it out.

I charge mine every two days, however I could probably get another 5 to 10 hours out of it. I have GPS turned off, but everything else is on. I have Coffee, Mini Launcher, Facer, IFTTT, and a few other apps installed.

I charge every couple of days or so, and use it for reading notifications through the day, controlling spotify on the phone. Also running IFTTT, Facer, Mini Launcher, and using Sleep as Android at night (latest build worked wonders for this - before this I'd have to be charging every day.)

Hello,
How to disable GPS? Is it "localization services" in settings? Can you allways use "Google fit" correctly without it? Because without disable my SW3 last around 60h with : fit, notifications, ghostracer (gps for running around 45 minutes), watchmaker, wear mini launcher.
Thanks

My watch lasts me around 2 days when I sleep I put cinema mode on so the screen doesnt auto wake up

I've had mine for a week now today. I've had a couple very heavy use days where it lasted almost exactly 24 hours. However, yesterday was a moderate-to-heavy use day (worn and used for about 10 hours plus a little tinkering later in the night) and it still had 50% battery this morning. Resting much of the weekend when I got it, it had around 30% battery Monday morning. So it has varied with use, of course, but I'm pretty happy with the life. I knew a lesser battery wouldn't cut it on my heavy use days when I'm bored at work.

So, had my watch since Wed, and ben doing a good test since Sat morning:
Constantly paired with my S4
Screen off/Gesture off/Tap on
Non theater mode
Starting at 10:30Am Sat taking it off the charger, i have worn it since; checked a few emails, send a few voice texts, checked weather, etc. Currently (1:30 Mon), i am at 63%.
Frankly, i am more than happy with that battery life. If i can get away with charging it every few days casual use, without having to pair/unpair to conserve, i am sold. Now they just need to release the steel band for separate purchase (or a dedicated holder for band choice) so i can customize as much as my watch face.
So, here i am at 11:30 on Tuesday, and i am now at 10%; this included a GPS monitored walk, dozens of voice texts, emails received, time checked a bunch, and other misc fiddling with it. While the dreamer in me dreams of weeks of battery life, the realist in me is more than happy with 3.5 days of active life.

72 hour battery life 2% left
Edit: This is with display ON all the time. Tilt to wake OFF. No gps.
