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?

For the past 2 nights i have been experiencing this
had 50% power left the night before...
after 6 hours sleep
phone is out of battery @@
Now that aint right, im guessing something is running under locked screen and iono what!!! but i always jump out of any program when im about to sleep too, so it cant be because of that
In the past, i could have standby time for a long period especially after one night. But the past two days when i woke up, it always ran out of battery!! Also when i charged my phone to full life, i sometimes come back after a hour or two to find it dead!!!
This has never happened before and im wondering what could be the cause of it.
In the past i could leave my wifi, bluetooth, location on and it would still last overnight and i wasnt running any program
It cant be because of alphajax right? I mean i did install that two nights ago :\
That is really weird, which phone do you have? I have the hd7 and get 2 days between charges most of the time. Have you tried uninstalling alphajax to see if that helps?
I use a HTC mozart 7
Im gonna try uninstalling a few apps to see if that helps or switch to my secondary battery pack
just to let you know i watch videos before i go to sleep and because its get so hot it drains battery faster, even though i had 50% after I finished watching it went all out in about 8 hours of sleep.
That sounds highly likely, i was playing a game before that, then left it alone for 1 hour, check still had 50% battery, and then went to sleep
woke up with a dead phone
I will confirm that when I have overworked my focus, ie several hours of video and games, the battery can get very hot and if I wait until I get the low power warning, plugging it into my laptop USB can't keep up with the drain.

ok this is ridiculous
in 3 hours i lost 30% power on standby
ITS ON BLOODY STANDBY!!! lol i cant figure out whats causing it. I didnt use the phone for anything at all then put it to charge till 100%. Started counting down time...
If I were you and you dont mind loodsing games aves etc, Id try a hard reset and if that doesnt solve the problem go to LG and ask them to fix it if there may be a fault.
Sorry I cant help further and Goodluck!

I've had this issue as well. This has been going on for months for me. Before NoDo and the pre-update.
Perhaps the battery isn't calibrated properly. Mine shoots down to 50% over the day but sometimes an hour or so after I hit fifty the battery goes critical then dies.
Battery Drain
I have the Samsung Focus. Pre NoDo I could get maybe 18 hrs in standby, and charging from USB on my computer was not happening. I had to plug it into the wall. If I actually used my phone for maps, calls, web or whatever I would get about 10 hr's depending how "how much I used it". This was with EVERYTHING turned off. Bluetooth, location services, feedback, anything and everthing I could disable. After NoDo, I get about 2 days, and now it will charge from my computers USB. Go figure.
All I can guess is there was some sort of corruption in the ROM.
Just a side note, does anybody know what "NoDo" stands for???
Answer: No Donuts
Before the February and March updates, I woke up one day to see my battery had drained from 100% to 0% in about 6 hours of sleep. After recovering from an angry awakening next morning, I paid a lot of attention to how the battery was draining. So I charged up to 100%, went to work on the tube as I always do, and noticed how after about 45 minutes, the battery was down to 50%. That was just some music playback and checking a few mobile websites.
In the end I remembered the day before I had installed two applications, one of them being Lyrics and the other one being a BPM (beats per minute) detector for getting the tempo of a music track. I decided to remove that application and, voilá, the battery drain stopped. I would have uninstalled the Lyrics app but this was already taking me to a decent power usage state, so I stopped there.
If I were you I would check recently installed apps to make sure you don't have a power drainer that's magically working in the background when you put the phone to sleep.
Did you disable feedback in settings. That extended my battery life considerably

I know what your going through, but i found the solution.
Your mobile data is constantly running to check for updates on the game and push notifications. Disable data connection whenever your not using it, and i swear you will see a massive improvement. I have a htc trophy and its notorious for its bad battery. I used to only get 4-6 hours out of it, and now i get 12-14, with WiFi.
That reminded me.... alphajax uses push (although i had disabled it) to notify the user if the other player had made a move...
It all seems LOGICAL that alphajax is the culprit here....
but i also have lyrics, how does that app affect the battery???
Hey, I'm running (CDMA) CM 9 (6-18 build winner00) and Franco . Kernel nightly #194 with the 512mhz GPU. This morning I unplugged my phone and let it sit for a little and ended up with this: (attached)
Any idea? I checked BetterBatteryStats and I don't have any noticeable wake locks either.
I'm kind of confused what I'm looking at but what I think you mean is that you never touched your phone for an hour, yet your screen was on for 30 minutes? I guess something was keeping your screen on without any user input. Have you checked Settings --> Display --> sleep set to (30 seconds or whatever you want) of inactivity? Perhaps it is a misbehaving app that is causing your screen to stay on.
Oh my bad, should have clarified. With those stats and screen time, I don't know how I can already be at 82% :/

Actually... that's quite average if not just a tiny bit below average. A battery usually doesn't charge all the way to 100%, it tops off at around 95-98%, so you went down 13-16% with over half an hour of screen time and approximately an hour of normal time. 4+ hours screen time is actually considered good, which is the track that you are on (13%/30 minutes). Standby will drastically save you battery as well... which can translate to 15+ hours and 3+ hours of screen time (depends on the user). Also to take into account, the first 10-20% of the battery drains faster than the rest of it as well.
So I just got my Note 2 this week and I'm only getting about 9hrs of use before hiring 30%. I checked a bunch of reviews and they were saying they usually got a day in a half with moderate use. How about u guys? How long are u guys getting of of your phone? Are u rooted? Using a juice app? Is an SD card inserted? How long does it take for your battery to recharge?

I have to charge it in between, but I am always on it. Still the best battery life I have gotten out of a phone since razr maxx.

I've been getting 1.5 to 2 days on mine with my normal usage.
I spent a few days at my in laws where I used it a solid 8 hours near continuously and ran it down to 15%.
I was in an area of no cell coverage and had wifi calling running all day.
16 hours yesterday with moderate to high usage. 40 minutes calls, 25 sms, 6 mms, 10 photos + retouching, 3 app updates, 1 install and a total of about 3-4 hours greader/browser reading. Wifi on, 3g on, power saving on and sync on. Display brightness between lowest and 50%. Display on time 48%. 19% battery remaining. Stock international version, unrooted. No LTE.
I have no idea how long it takes to charge. Sorry.
Trivia: The word "Nomofobi" (swedish) or "Nomophobia!?" (English) has been added to the Swedish dictiodary. It is the fear of running out of juice on your mobile phone!
My nomophobia disappeared with the purchase of my Note II.
I hope you sort your battery issues out.
Question, those with insane battery life, are you rooted? The first day I got the phone, it had 16 hours before going down to 5% battery life, and I had about 6 hours of screen time. I wasn't rooted.
I rooted yesterday, and the battery life today was about 12 hours, and its at about 20% battery life.
I was curious, maybe rooting the phone has a parasitic effect on the battery. All I did was remove T-Mobile's bloat ware, nothing else.
I don't see any difference in battery life pre-rooting and post-rooting. I consistently average around 16-20 hrs depending on usage. Typical day use for me is to take it off the charger at 6 am, then I usually have 1 to 2 hrs streaming on 3g, another 2 hrs streaming on wifi - all using Plex. Youtube about 1 hr, maybe 1-3 calls lasting 5 mins avg., 1 hr playing games, and about 1-2 hrs browsing internet. I'm not a heavy texter or gmail, since usually I can do that on my laptop at work.
I usually don't put the phone back on the charger until around 12 or 1 am, with about 14% left. I usually have wifi on, gps on, sync on, brightness level around 10-20% except outdoors (then it's full brightness), power saving mode on, and screen time out at 1 minute.
I had realized that I had the brightness set to full brightness since early in the morning lol. All in all, I don't know any phone that would last all day with full brightness and doing all I did.

Thanks for the responses guys, ive turned on power saver mode and I'm starting to notice a difference. Hopefully I can get 16hrs like the rest of u guys
The battery life is good and stays longer by not using it or talking on the phone with it

Two hours of screen time and the battery is at 79%... Doesn't seem normal. Going to take it back and try and get it replaced, not root and see what happens.

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.
