I have charged my Nexus One yesterday for the first time. I live in holland so i had to use my USB cable, and the power adapter that came with my HTC hero to plug my USB cable in.
After the phone was charged 100%, i disconnected it from the charger and only downloaded + added a widget to my home screen. After i did that the battery was already down tot 97% :O:O
Is it defective ?
i noticed having to complete a few charge cycles.. charge fully, use it till dead, charge again
now it seems to hold out much longer
Hmm ok i'll try that. But did yours also drain this fast?
what setting is your screen on? seriously though, im sure some other battery experts here would know, but i think they take a few cycles to get to maximum efficiency

What do you mean with screen setting, and what should i put it on?
Sorry totally new to the phone hehe
I've noticed this too. However as soon as the battery reaches around 50% it takes a lot more to drain so it evens out in the end I guess

Hmm ok so it also went that fast on your phone? i have been using it for about an hour now and its down to about ~90% =\, concerns me a bit.
Found out something else, concering the usage of the screen. When i look here:
Menu -> Settings -> About Phone -> Battery Use
The phone tells what uses the battery the most or something, but the strange thing is that it says:
Display 55%
Isn't that very high? Maybe that is causing my battery to drain so fast
Battery meters are not an exact science. Its using what it knows about the battery's state to guess of how much % is remaining. The battery meter will need to be calibrated once, and then overall battery should improve with your next normal 3-6 full charges.
Again, you do not need to and you shouldn't repeatedly drain the battery to 0, only once is this needed to set the phones battery meter, unless you clear it (possible within amon ra's bootloader).
As for your observation, yes that is completely normal, there is not a whole lot of definition within 3% of battery as far as displaying it. What the real picture? Enter in #*#*4363*#*# on your dial pad and then go to battery information, and you'll see the accurate voltage. (this is also accessible from "spare parts" if you have it)

All %'s here are vs the amount of time on battery (shown at the top in h:m). If you just unplugged your phone and you go looking here, you'll see the display % VERY HIGH... because the screen has been on the entire time its been unplugged
Its a % after all of the usage since last unplugged.
i've noticed my battery life is much better since i got the desktop dock.. lots of people charge until the light turns green then immediately grab it and start using..
leave it for another hour or two and it seems to get much better.
dont know if anyone else has noticed this but the top corner indicator light turns green once the battery goes somewhere over 90%, leaving it charge longer will get you to 100

You probably found this by now, but one flick to the left and you should have a widget for WiFi, GPS, etc. The far right one toggles 3 levels of screen brightness. The brightest two settings really suck down battery.
just a tip, when you are draining it to recalibrate the battery, after you get to the point that the phone shuts off, boot into the bootloader and run that thing till it completely dies... i did this for my phone, sat it in bootloader with a bright ass screen for like 15 min before it finally finished off... get every last ounce of juice out of it before you start charging it back up
Hmm thanks for al the reactions guys. I'm going to recalibrate my battery now, and lets see if that helps a bit .
Then i have a other question, its not about my battery but since i already have a open topic i dont want to create another one .
Can anyone of you test the following:
When you are calling with someone, and your calling volume is on the maximum (so the volume of the speaker that you hold against your ear). Can anyone notice a little crack from the speaker when the other person talks a bit loud or make's a loud noise? I'm wondering if there is something wrong with mine. With several tones the ear speaker cracks a little bit, like the sound is to loud or something?

Yep sounds about the same on my phone, dont worry about it lol
The draining thing is from the old nickel days, the lithium batteries are made for daily use so just treat the phone as you would normally. The battery will get better as time goes by.
Also I am not having that problem with the speaker
Hmm, I have my device since last week (Netherlands) and the battery usage is frightening. Sucking it dry in about 24 hours. I haven't let it die out completely though: I thought lithium batteries were not supposed to be used that way. Ni-Cad batteries were used that way.
Ah, see here:
Guidelines for prolonging lithium-ion battery life
Lithium-ion batteries should never be depleted below their minimum voltage (2.4 to 2.8 V/cell, depending on chemistry). If a lithium-ion battery is stored with too low a charge, there is a risk that the charge will drop below the low-voltage threshold, resulting in an unrecoverable dead battery.[citation needed] Usually this does not instantly damage the battery itself but a charger or device which uses that battery will refuse to charge a dead battery. The battery appears to be dead or not existent because the protection circuit disables further discharging and there is zero voltage on the battery terminals.
Lithium-ion batteries should be kept cool. Ideally they are stored in a refrigerator.[citation needed]
Aging will take its toll much faster at high temperatures.[citation needed]
[edit] Prolonging life in multiple cells through cell balancing
Analog front ends that balance cells and eliminate mismatches of cells in series or parallel significantly improve battery efficiency and increase the overall pack capacity. As the number of cells and load currents increase, the potential for mismatch also increases. There are two kinds of mismatch in the pack: state-of-charge (SOC) and capacity/energy (C/E) mismatch. Though the SOC mismatch is more common, each problem limits the pack capacity (mA·h) to the capacity of the weakest cell.

So, if you want to brick your battery, by all means, suck out all the power.
i have a mytouch but i think the things i do can be used with all androids....first recalibrating is a good way to get a fresh battery...then the brightness also helps along with any wireless things u dont use like wifi gps etc.. they should be turned off an brightness should be low...i have downloaded a app lately called automatic task killer..i think this is better than any other task manager because other task managers dont kill apps wen phone is on standby ..apps r still running wen screen is off an automatic task killer kills them..i think u should download this and also have a task manager to kill apps wen u use the phone..another thing is charging the phone wen its completely off..wait until the the light turns green then leave it on for another hour or two then turn it back on....i have seen an increase in bettery life by doing all this...any one esle have any tips ..let me kno
I went to bed with the phone charged to 100% or atleast very close to it since it had been plugged into my laptop for a few hours.
Unplugged it and left it at bedside at 12:00am
Checked the time at 7:00am (didn't bother to look at battery life).
By 10:00am the phone wasn't responding, kept rebooting with a red battery icon. I plugged it into the wall charger and it booted up showing 0% on the battery.
I also had it on low power mode: everything off and mobile data set to 2g only. I also had no activity on the phone: no calls, emails or notifications.
I've done this before and I'll usually wake up to it in the 90% area of battery life, but now it's completely dead?!
Anyone haves omething like this occur?

Mm.. well, first thing I'd do is check your widgets/apps running. Some of them leave a WakeLock open, and force CPU to run at 100%.. that'd kill the battery.
Another thing to check is any big data parsing apps, like RSS with webpages for example (NewsRob).. they are excellent apps, but if you set them up for constant sync they will kill ur battery.
Unless your battery is a complete mess, there is no reason why it should drain so fast, unless there are some nasty apps running.
BTW, check out this thread: http://forum.xda-developers.com/showthread.php?t=669497
You really don't have to worry about using 2G over 3G (EDGE drains MORE power than 3G, actually) and turning everything off for battery power. Your problem is elsewhere.
It happened to me once. Woke up to a completely dead phone. I assume something I was running got out of hand. Nothing I had installed regularly kept it awake, but it could have been a bug in something that used 100% CPU, or at least kept the CPU awake the whole night.

It's small things, for example a CPU meter widget I had secretly ran a WakeLock and kept my CPU at 998MHz all the time to monitor it.
Or, could be just a poorly written app/widget. Not saying that this is the definite reason, but this is the first thing I'd check for.
how do i know if my phone is set at 324MHz even on sleep/standby?
i have it setup to 324/224 standby, but i dont really know if the phone is going to those clock speeds as soon as its on standby.

I have a few apps that sync, such as Pure Calendar / Messenger but nothing that should drain it that quickly. I hadn't installed any new apps and never had this occur, so maybe it's a bug where something caused the CPU to run at full overnight. I'll leave it unplugged tonight too and see what happens.
I had everything turned off. No email, no sync, no wifi, no gps, nothing. I fully charged the battery and unplugged it before I left. Display was never turned on. I wanted to see a completely isolated battery test. The only applications I had active according to my task manager was Launcher Pro.
Time on 10 hours 20 minutes
Battery life left 60%
Battery used 40%
Cell Standby - 40%
Phone Idle - 30%
Android System 20%
Calls (1 missed call) 5%
Display 3%
Maps 2% (Why does maps show up?)
Again this is with absolutely 0 use or syncing going on. Left phone at home, turned on and immediately checked stats when I got back from work.
According to this small test I can't even last a day on a full charge even if I left it completely alone.
Thoughts?

In 1.5 day of standby with every radio off and no sim, my phone only lost about 5% with stock JI6.
I think it is a cool idea. I find that 5% usage for one missed call is very bad. I have really suspected that voice calls kill this battery and that seems to add evidence. 5% for a missed call? That is messed up.
I think this is the aspect of battery life that doesn't get addressed enough: drain during standby. Of course everyone expects to lose some power while the display is on and syncing/other processes are running--but what about when the phone is left untouched? Here are 3 ideas:
3g is a notorious battery drain even when the phone is not being used--use 2g instead.
Freeze or uninstall media hub and other running processes that attempt to run/connect to servers in the background. I removed dmservice, media hub, and all drm processes and this seemed to be helpful.
Use a custom rom--these appear to hold power in standby better than stock roms do.

Cell Standby indicates that there is an activity that polls something from the network.
if you are so concerned about what it might be, you can see when and how much data is being used by going to your TMO account online and check for the data usage - one of the good features TMO put in place is actually tell you when your phone connected to get what amount of data over the data connection, does not tell you what it was doing though.
Yeah, something is going very wrong in your phone. When my phone is on standby with just 2G on it drains less than 1% per hour. I would definitely recommend getting rid of the drm service and media hub (and Daily Briefing). I also use Autostarts to keep all kinds of random programs from starting at inappropriate times (Really Slacker, does your app need to launch every time the time zone changes?)

According to Samsung the phone should last 450 hours in standby mode...

I wonder if Samsung's definition of "standby mode" is what the rest of us call "off".
I've never had any kind of batt life with this phone...charge everday overnight...start work at 8, use here and there for navi (around 10 mins max, maybe 2x a day) about 30 min avg talk...and mp3 player...get home by 4 and always at 30% or (most often ) less...have had stock/ bionix roms, never changed, no matter what build....it's pathetic..called tmo, they said there are no known issues with batt on this phone...wow...do a google search on it..anyways, they are sending out a new batt..I hope I just got a bad one...seems very random tho, some ppl have all radios on ,screen all the way up and get 10+ hrs...if i left my screen on (say navi on) for more then an hour straight I'd be out of battery..very weird..praying new batt is better...

Does it seem like youre just not getting the battery life you should from your phone? Do all your other friends keep going while you slowly putter into a shutdown? Well pout no more! Simply follow these steps to clear your batter information from the phone and your phone will act better then new! :)
1. Charge phone completely, leave plugged into power
2. Boot into recovery
3. Wipe battery stats
4. Reboot to normal
5. Remove power cable
6. Drain that sucker all the way
7. Recharge fully
8. Rejoice!"
I turned my phone off today. Then I left the house. When I got back the battery was glad to see me. Seriously, I've read just about everyone and almost started my own battery disturbance thread. I've come up with a new thought at least for me. I don't care any more. I have electricity. I have a spare battery and a charger. If my phone wants to last a whole day. Yay! If I use it more because of some game with angry birds or cards or dice, great. I've reached that Mark Twain moment somewhat tweaked when he said,
“Age is an issue of mind over matter. If you don't mind, it doesn't matter.”
I'll tweak it with the last 27% of battery left in my feeble vibrant to:
"battery is an issue of mind over matter. If you don't mind, it won't matter".
Enough already I say! Lets spare the air. Batteries are meant to be used
Back to the regular reading of all the battery threads now.
I think I had the same issue as you. Cell standby was the biggest drain. When you tap on that, do you see 50% time without signal? If that's the case, this seems to be a bug in Android which was somehow introduced in JI6. The best solution I've found so far is after every boot to put your phone in flight mode for a few seconds and back. This fixes the radio glitch, your time without signal should go down way under 50%, and battery drain should stop. Hope that helps.
You should recondition your battery:
Fully charge
Reboot into recovery wipe battery information
Reboot into OS
Unplug power cable
Let battery FULLY drain (do not plug in until fully dead)
FULLY charge battery (do not unplug until fully charged)
This reconditioning should be done after every ROM flash.
Ye, my battery just went from 48% to 3% in about 3 minutes. Does anyone have any idea why this is?
Same problem here. From about 43 % down to 7 % while it started to charge the battery with the original charger. Afterwards the Tab didn´t charge at all. Battery drained and got very warm.
I Called Vodafone and was told i have to send the Tab in for fixing. I hate waiting for the tablet 3 weeks.
Update: After 2 hrs. of waiting the Tab cooled down and i was able to start it again. Did a factory reset and was able to charge again with the wall mount charger.
Just wanted to bump this as my battery life is miserable and it discharges really fast in standby...
My HTC desire has been on for 52 hours, used for a lot of stuff and is at 20% battery.
The Tab charges to 100%, I unplug it at night and in the morning it has lost approx 10%, I leave it a few more hours and it't down to around 60%. This is with no use and no apps running!
I've tried killing apps or leaving them in memory and it doesn't seem to make much difference. I also use setcpu and have a profile where the CPU speed decreases when in standby to conserve battery?!
If I charge to 100% and use it constantly, I get fair life out of it maybe 4-6 hours of light use - some streaming over wifi, web surfing, kindle, sudoku etc. If I use it occasionally or heavily though, it dies very quick and if I leave it at about 40% on the evening, it's generally dead in the morning.
Why does it discharge so fast in standby??
Check to see if it continually searching for a signal. I've noticed that mine loses a lot of power constantly searching for a signal, cellular and wifi. So, I used airplane mode to conserve power. Remember that it syncs to different services that require it to periodically download data. That may be your issue.

Thanks Chuck, I use it in airplane mode all the time and only use web over wifi (bought unconnected in the UK). Would it still be syncing for email etc? I didn't think it could turn on wifi and sync itself but only when I turn wifi on. I always turn wifi off when not in use. I had problems with widgetlocker asking for superuser permission quite often and that killed the battery quicker so I removed that until it's fixed and saw an improvement.
I'm not seeing the times that other people are though, losing at least 10% overnight and there's nothing really running.
I installed battery doctor and the times it quotes are high for different types of usage and nowhere near what I'm getting.
I'll make sure email and calendar are set to manual update, adjust brightness etc and see what happens. It seemed better when I first got it so perhaps an app is draining it? I installed system panel to monitor this but it's hard to see what is actually draining it, any recommendations anyone???
Quite disappointed at the moment, ipads barely drop 1% overnight and I'd rather not have to turn it off to conserve battery when it should maintain it in standby...
Check the task manager and see what application are running. Also you can go in settings- about device - battery use to see if a specific application is using your battery out of normal. Also , the display is generally the battery hog, you may have set it to a super high level. One last thing you may have the buggy 3d gallery app, and it will show in the battery usage.
P_
this is an interesting problem. its very similar to the Apple Macbook Air.
The Macbook Air was very thin - very nice looking - however it needed to depend on wifi to do most things.
the association i am trying to build here is this: the Tab needs a bluethooth headset so you dont get all your calls broad-casted over speakers and that could drain the battery a lot.
for me the battery drainage didnt seem so bad and its been on for the last 36 or so hours. the battery icon didnt look like it moved so much and i was impressed considering this thing had a gigantic battery. then i loaded up a utility that read the battery and said i had 59% so my jaw dropped. not only is the battery indicator wrong there maybe rogue processes casuing the battery drainage. and this is on 2.2 which is supposed to be somewhat battery efficient.
i dont know - frustration is what i am all about here with this thing. it seems that every time i buy a new android device i want to move to another android device. no one is getting the damn thing correctly setup.
Am at work right Now, Charged the tab overnight, just few minutes ago my battery said 60% left and now the tab is completely dead, wont turn on, I ll wait until i get home to charge, fingers crossed.

I am experiencing the same thing. Tab on flight mode and charged to 100% overnight. Unplugged at 9am, still on flight mode with no apps running, and it is 88% at 2pm.
12% drop in 5 hours with no usage whatsoever is way too much imo, comparing let say to my HD2, even not in flight mode. Wonder if they have a bad batch of battery for certain tabs........
Just wanna report back after my last post. When the percentage was dropped to 85%, I did a reboot. And guess what, now it displays 95% !!!!!!
5% drop from the morning til now in flight mode seems right and okay. Does it mean the tab is miscalculating the percent left?
PS.
I have been following the voltage in Spare parts this morning. All settings are the same (no apps opened, same screen brightness and in flight mode. Only turn on to record voltage)
94% - 4087mV
91% - 4081mV
88% - 4075mV
85% - 4067mV
But then after the reboot
95% - 4040mV
Man, I am not sure whats going on here........

let me jump in here again and share a similar deli-ma i had with my X10i.
while i was messing around with some custom roms i decided to stick to one that looked somewhat nice. well the funny thing is the battery indicator would always display 100% and for about 4 hours it would drop ever so slightly. then i removed the battery and put it back in -- the battery indicator showed 0% and i got a red light flashing ....
after screwing around with it for a bit i re-flashed the stock firmware from Sony-Ericsson and magically my battery meter and my battery worked fine.
so to sum up -- it maybe a software issue like the one i had on my SE X10i above?
Hi guys,
Hope you all doing great.
Guys i have LG V20 n using from last year. It was working great without any issue. Battery timing was awesome. Giving me 5:30 to 6 hours screen on time. Almost day and Half on normal use. 2 days back something happened no idea what. Now phone idle using more then screen on time and wifi is always on even its off. I tired to uninstall app, then factory reset but still same.... No luck.... Any solution ??
Go to your location setting use the tab in upper right, click setting and turn wifi scanning off.
I tried this but no luck
As i mentioned i tried everything thing, like location off, wifi and Bluetooth scanning off, play services off, Almost everything is off, but still same. No luck...

Try to install battery monitor application (I use betterbatterystats) to find out what is causing your idle drain. But to be honest, I've never got 5-6 SOT. My idle drain is about 0,7% per hour with greenify, managed Google play services wakeup, custom kernel, kernel adiutor and about 80 apps on board.
I'll try and help the best I can..
Within the last year or so..I have been reading about this issue quite often. That is, people posting about "Phone Idle" having high percentage in battery stats. And then they are off to hunt down the culprit. The truth is, "Phone Idle" is NOT eating up your battery. Phone Idle is just that.... Time the phone has spent being idle (being still, or CPU/Battery not being used). Or in this case, percentage of total battery "usage" that belongs to "Phone Idle". In actuality, phone idle isn't "using" anything. The "usage" for phone idle is really time NOT used. A higher percentage is better. If your phone sat for 2 days straight without being used...the phone idle % will be real high. Also, you can't "Greenify" phone idle. You only greenify phone idle when you greenify other apps.....think about it.
And as for Wifi. The Wifi radio on this phone is a bit more power hungry. It doesn't even include any power saving options that some phones, like my Samsung S4 has. My S4 used on average from 2% - 6% depending on signal strength. The V20 can use from 7% - 11% ..again depending on signal strength. If you leave Wifi on overnight and it's in bad proximity to the router..10-11% is normal.
What is your average signal strength for your 4G and cellular (calls)? CDMA has 1X, I'm not sure what GSM uses. If it's in the high 90's and higher, that right there could be chewing up your battery. Phone radio often doesn't even show on the usage list.
How often do you need to charge? Also how much time between a charge and what is your usual screen on time now..after you wrote this post? Phone idle is only at the top because the "idle" time now exceeds the amount of time you have your screen on. ......don't take this the wrong way but some people think the phone idle is actually something that's draining the battery. It's not..it's just placed within the list. Ignore the Mah it shows for it. That just assumes it's some app and it tries to convert everything into mah..and I really don't know how accurate that is. But it obviously doesn't apply to Phone Idle. Speaking of...what is the amount of phone idle time?
