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
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.

its been charging for 2 hours now and battery is not even warm to the touch plus no power yet... if charging is what you intended....
more than 3 hours of charging and counting and still no sign of life...This device is just 8 days old today from Brand new...

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?
I got my hands on the zerolemon 7500mah battery for my S4 about a month and a half ago and it is amazing.
With normal use (multiple e-mail push accounts, location tracking, wi-fi enabled etc) I get about 15% battery drop a day.
After a full charge, battery apps tell me "17-20 hours available."
Somehow the battery logic for android phones seems a bit off, it seems to be more a guestimate towards the current power use then the actual recorded battery run time.
Is there anything that can actually profile a battery ? Record the power use and battery voltage levels and give a more accurate picture over time ?
I *thought* android actually did this but apparently not, or its been because I'm only on my 4th charge since getting the battery but i'd like some confirmation if that's the case
I love this battery, this kind of battery life should be standard, only Android can't really deal with it properly yet .. the 15% battery alarm especially can be a pain: 'what do you mean battery low, its at 15% that's a full 24 hours!' and it still puts the phone in power saving mode.
I've been having this strange problem these last few weeks. It happens in different ways.
1. Bellow 25% phone randomly shuts off then when i reboot its 0% battery.
2. Bellow 25% at random % I lose phone signal then the phone starts to lag and capacitive keys don't work then the phone shuts off and when i power it on its at 0%.
3. Phone gets to 15% i plug it in to charge, it doesn't charge but discharges to 0% then shuts off and after that it charges.
If i remove the battery then put it back in after it says 0% it may show 30%/20/15/13/25/30 etc. Sometime it doesn't charge after 87% or 92%. Is it the battery or is something else at fault? Also i can't get more then 2h15m screen time whatever i do and wifi drain is 30% in gsam.
Earlier I had same problemes on my Note 1 and it was because of my battery. Probably your problemes are becuse of your battery too.
Ok I will try a new battery.
I have exactly the same problem!!!!
Like exactly.
However I'd like to add some things:
1. Sometimes the radio signal for mobile starts randomly cutting in and out. It will be full bars, LTE, then nothing, no signal symbol. Then Full bars again, then no signal. In 1 minute revolutions. I am not physically moving during this time.
2. Even at near full battery the phone will get super laggy, stutter, and then finally crash. Once it reboots the battery will be 40% or something. Not super low but lower.
3. The camera seems to have a huge effect as well. I will open the camera, take a picture, and the picture won't save...it will just start to freeze the phone up until I have to pull the battery or it reboots on its own.
I also have a new battery coming in the mail.
However I should note that I am Note 4 910-H using a 910-C variant Custom ROM.
I was worried it was the special Modem I flashed to make the C variant ROM work on my H variant phone that was causing the problem.
Great, but unfortunate to see someone else having this issue too.
Ill post results of the new battery here.
Btw, ive been able to resurrect it from a very low state of charge (3% etc). The only way to do this is to use my fast charger. The fast charger is the only thing that will save it. Even then it takes ages to charge and gets white hot while it does. Its like the fast charger is battling for charge against some unknown force.
Post if you remember when you get your new battery. Hope that fixes it for you.
hi
my note 4 910c become very hot when i use the internet , can i change the modem from lower android like 4.2 to android 6 ? is it work ?
I have exactly the same problem and please if any1 finds any solution just share it here... I tried almost everything but not a new battery.
Battery Calibration By All The Ways, Battery Quick Start via *#0228#, Many Custom ROMs, Many Custom Kernels and Many Stock ROMs and the problem still the same even after I cleanly installed stock 6.0.1 ... Any help please.
Thanks in advance.
New Battery fixed 99% of my problems.
However the phone still randomly freezes and disconnects from cell service.
I think its the modem driver. Freezing might also be due to sd card.
Hello guys!
I've been wondering - how your phones behave when they run out of juice?
All my previous phones were going from 100% to 1% without any problems, then, when the battery was at 0% there was a message that Android is shutting down and the phone then turned off. Normal thing.
However on my G6, I've NEVER had such message, also my battery never went to 0% or even 1%. It always stays at 3% for some time, then suddenly it drops to like... 2% and then it shuts down instantly without any warning. Sometimes it shuts down at 3%... Just turns off, no message displayed.
And before you reply - yes, I know that I should never drop the battery that low but sometimes it's not that easy when I'm travelling somewhere and my powerbank is also dead. But I'm very curious how your phones behave, that's why I'm asking
Besides - one time I had a problem with my battery when it was around 30% and my phone cooled down to like... 0 degrees Celsius. It also turned off instantly and was dead until I warmed it up. Did you have such problem too?
Thanks in advance!
"unfortunately" LGs have always had that behavior, similar to the "longer 100%".
About this some users believed that LG battery percentage is calculated differently according to the user usage, but who knows the truth...
Only thing I could say you for certain is that it's "normal" on LGs

So, my last 5 phones was an LG and i guarantee you this is normal with LG phones.
In the first ten or eleven chargings the phone should drop like 5, 4, 3, 2, 1 and shut down at 1% but fast when change from 2 to 1.
when well calibrated i mean let it discharge fully 1 time per month and they only should shut down when it reach 2%. LG phones only go at 1% when new and always go off at 2.
I dont know why your phone dont display the shutting down message isnt normal because my LG phones everyone of them show it, maybe is too fast and you dont see it was i belive it is.
My G6 was only about 1 week and only shutting off at 1% but my V10 shut down almost at 3%.
The 100% bug is an LG thing but for me this is a calibration method different than Sony, because sony will go 0% before go off and LG dont.
DOnt you worry, is normal but if you can charge it when have 30 - 35% is better because leave it discharging too many times lowers the cicle of life than a battery can last.
