I thought I'd write this thread simply to see if it can work for others.
I have read throughout this site that it's good to allow your battery to become completely drained, and then recharge via the power adaptor. Some people even suggest to do it 2-3 times.
Yesterday, for the second time since I bought the phone several weeks ago, I decided to allow the battery to become completely drained. I then charged it using ONLY the power adaptor.
Results?
Before, when in standby mode, no radio, wifi off, screen off, I would lose about 1% battery power per hour through the night while sleeping.
This morning I was shocked. My battery was fully recharged just before midnight, and when I woke up at about 9am this morning, I had lost only 2%. Yes, it said 98% charge left.
WOOHOO!
Anyway, I guess it really does help to allow the battery to drain and fully recharge a few times in the beginning.

I seem to read somewhere that Lithium-ion batteries don't have to be drained to be charged properly. Moreover, it's just okay even if you keep on charging it with the green light on, i.e. reached fully-charged level. Well, I myself just got the HD2 and am pretty satisfied with its battery performance although I haven't really monitored it closely. I just charge it whenever I can.
I recycle my battery about once a month and it really helps.

You are right that it's perfectly acceptable to continually charge the HD2. You can't hurt the battery. I'm just saying that I tried this suggestion (from many other threads) and it seemed to improve my battery situation. It may not work for everyone, but at least it's something.

Peter,
This is the way to treat batteries if you want to get the best performance out of them. There are numerous posts on this issue on here but it does not matter how many times it is mentioned, people still don't read.
What you get is a load of comments about how poor the battery life is without them going through the conditioning process that will get the best out of their battery, irrespective of what type of battery it is.
It is always advised that you go through several cycles of full charge and full discharge, preferably when the battery is new, to get best results, and to do this on a regular basis throughout the life of the battery.
Undertake a good deed for the day; spread the word!

You're right. I've read so many different opinions on this matter, including a lot of research on the Internet. There really does not seem to be any consensus on the matter.
One thing's for sure, I will continue to cycle through full charge and full discharge on a regular basis, perhaps once a month. In the meantime, I'll just top it off every day.
Thanks.

There is a more fundamental point to all this.
Its not the charging and discharging that makes the difference.
Its the working of the battery under load that allows the barry to achieve maximum capacity.
And constantly discharging/draining the battery will have a negative effect over time, shortening life span and usability.
Just charge and use as much as you can.

Strange that all previous phones I had I charged the same way - drain then charge for 12hrs first three times, and then drain / charge as I go - and battery always lasted satisfactorily to me ... I know it is a li-ion battery but for me it works every time and I am sticking to it until they invent better longer lasting batteries
What happens when you Recycle them tho Do you not have to buy another one as I see there not cheap.

I think he/she means re-cycle as in a charge/discharge cycle
I recently bought a HD2 and was reading very differing advice concerning teaching maximum battery capacity.
-do not let the battery go fully dry, it might harm it (source: wikipedia)
-cycle the battery, drain and fully charge a few times.
-charge as often and much as you can, the battery has no no memory, top it off as you like.
So,,,
I take it now, that the battery likes being used hard, especially when new.
Drain to 7% or so, recharge, drain till 7% or so, a few times.
So do not try to find energy saving mods in the beginning, but work it hard.
I noticed I get a huge battery drain increase when I set the screen backlight to 100 instead of 40. and what a nice display it is
So I figure thats nice way to get to know the HD2, to use it hard and bright, until the battery is 'conditioned' and I know what programs I love the extra brightness in.
I have not been able to drain the battery in a day of expected use yet, always had 23% left or so, which is almost a 4th..
Oh and sorry for off topic, but are any of you guys interested in the ebook reading capabilities on the device at all?
I use a free ebook reader called 'freda' on 'night mode' with black background and red letters, and due to the screen size it is so easy to use the HD2 as an ebook.
I snug into bed and read like 50 pages of an ebook and maybe drift off and the device will auto goto sleep too, if I go first.
It's great.
After successfully booting into android for the first time my battery life in android skyrocketed down, but that didn't really bother me.
The real problem is that even in WINMO my battery life is less than half what it used to be, and even after a night (8 hours) of charging (In a wall socket, not USB) its not at 100%
this has me very worried, any ideas? thanks in advance!
did you read anything before you started this thread...........
yes, i did. everyone is having a problem when they charge in android it gets to 90% then they switch to winmo and within minutes it picks back up to 100%.
this is not the case for me, my battery does not jump back up, it drains quickly even in winmo, and when it gets low its not just reading it improperly it just dies, so no this is not the same problem
did you know there are fixes .......and that your problem is not new at all....i am sorry to say that this is a know problem and you would want to ask in the thread of what build you are using and if you really wanted help you would post what build your using and what kernal , but no one can help you at all when you simply state you have battery issues
drain your battery in winmo till it dies, so the battery resets, then charge the battery again till full, it should be allright again.
thank you dipdap i will try that

I strongly advise you NOT to do so. Draining a Lithium-Ion battery entirely is detrimental to its overall life/capacity. So instead of ruining your battery (or going a step towards ruining it), simply turn off your phone, charge it until you get the green LED, boot back to WinMo and it should be alright. If it isn't, look for another way, but completely draining your battery should not be the method of choice.
nobody said to drain it copletely, just till winmo dies, which should be fine. I do this once every couple of months by accident, and have never had a problem. I agree that you should not drain the battery completely though, so, make sure as soon as winmo dies, plug in to a charger.
what rom are you running? I am using shubcraft 1.5 and mine charges to 99% And I can get a full day out of my battery with pretty decent use.
Are you using setcpu cause that could have a major impact also do you have wifi,gps or bt on. I know gps has been known to cause some major drain while in sleep mode.
There is also a thread where people are trying to find solutions to the high amount of drain in the development forum.
We use current widget to create a log and monitor Our drain. You should be seeing less than 10ma while sleep I usually see between 3-7ma while sleep
Funny how when you are watching your battery it drains faster. When you are watching the clock time goes slower.

You can look at this thread
http://forum.xda-developers.com/showthread.php?t=770903
It was very helpful for me to identify how much current is being used while in sleep mode and active.
Download "current widget" from market and monitor your current supply for 30 minutes during your phone's screen is off.
Yeah with the screen off you cant see any thing but thankfully the log will be written for the current widget every min.
If your current comes out to be bellow 10ma during this time then you are doing good and should last you one day of usage else you need to pinpoint what is drinking all the juice even while your phone sleeps
Read the thread ALL OF IT, it will help you understand better.
Cheers.
alright thanks for all the help guys, the battery drain actually worked although i felt strange doing it, but still my android life isn't so great, i would love for it to work completely though because the only wquivalent option on my carrier is the Captivate (Galaxy S) and that thing is ugly compared to the HD2
such problem
I have such problem with battery drain under WM, after i run and quit android, but i found a solution, just pull out your battery few times next just recharge it and it will be OK .
Hey Guys
just found this forum now, am in straight away
am using HTC wildfire for 2 weeks now, maybe less, when I got the phone i was so excited and turned it on immediately before charging, I do not know if this a reason for my battery to get empty too fast, I MUST charge it everyday, some days heavy use, but I have tested for normal use and still the same, as i saw in many threads all people are happy from the battery life.
so any idea to solve this silly weak battery.
cheers
This is Touch2 territory :S
Try a full discharge then a full recharge cycle. Let it die to the point that you can not get the phone to turn on and then recharge. These batteries should not need this but it might help.
So, I decided to finally root my SGSII..and everything went smoothly..n I was happy knowing that now I could do many things with my phone...it eas working normally with no issues but, after some weeks, my battery life was just awful..it wouldn't even last 15 hours..n I was worried..started searching for solutions, but didn't find them..n then Istarted getting used to to this poor battery life..
Now the interesting story..
One day,I went to fetch my SGSII n I was expecting it to be off, with no battery, n thats what happened,n I didn't even bother charging it..it remained fully discharged for, I think more than 24 h, then the next day, I needed it so, I fullY charged it, turned my phone on, n started using it..
by night I was expecting my phone to be fully discharged..BUT, it wasn't the case this time around as my phone's battery started working normally..just as it before...
Try it...at least it is not risky

Sorry, I saw empty post. My response is now useless.
But... how will I survive an entire 24 hours without my beloved SII?
Most people just learn why the battery drain occurred. And fix that.
Basically this works with Battery Cycles - discharging your phone from 100 to 0 and charging it all the way up again without interruption; has proved to be a handy way to keep a healthy battery life just as my SII has did.

They don't work. Ignore them. Simply charge your phone to 100% from flat and its battery will be calibrated.
Also disable chatting programs like msn messenger, whatsapp, kaokaotalk, facebook will save your battery. Those apps keep updating and sync at background.

Never had a issue with Whatsapp or Facebook when set to PUSH mode rather than scheduled updates.
Epic first post. I found that if I don't use my phone, the battery lasts longer than if I do use it. Hope others share their tips too, as there's a shortage of battery threads.
Its not that important that you wait 24 hours.
The most important thing is that you let your phone discharge until it has very few percents left or even shuts down by itself.
If you then fully charge it while it is shut down you should get much better battery results with your next circle :good:
battery life
my battery life is awsome!! after 22 hours of a very little bit of use i had 76 % battery life left !
siyah kernel 3.5.2
rootbox JB 2.0
i had almost 2 day with rr 2.6.1 and cm9 . i think that this is the perferct combination for baterry.
Leaving empty (0%) lithium-based battery without charging for more than 2 hours is stupid - lithium batteries are degrading very fast in empty state.
// tip for notebooks and phones
i getting also faced this problem too. Empty that battery and charge handphone on offline to make it fully chargging.

Don't worry about the battery life. Just use the phone through the day as God intended, dock it at home or in the office and charge it over night.

Hi everyone!
I got a Note 4 a few days ago and it has battery issues.
I got it second hand online from a guy I don't know. I'm from Romania, I think the phone is from the UK, it's Verizon branded. The model is SM-N910V and the Android version is 6.0.1. It's not rooted. I noticed this V version isn't very common.
The battery that came with it was pretty poor, it would drain in a few hours with minimal usage and the worst problem is the phone would suddenly shut down at about 30-35% battery life. Then it would go into a booting loop, without being able to actually boot until I plugged it in.
I bought a new genuine battery from a popular online store here (F64), battery life is better, but still with just wifi, it went to 50% in about 2 hours of browsing. Without wifi or data (very little), it lasted for a day and a half. But the phone suddenly shut down at 8% battery life, again going into a booting loop, without being able to actually boot until I plugged it in. I'd also like to mention, when the new battery came, it only had 4% battery life left (I heard they should come about half charged, is that true?) and also there were a few reviews from people who had to try multiple batteries from this store until they got lucky with a good one. Both the old and the new batteries look identical, I don't see any signs of counterfeit.
Should I return the battery and try a new one? Is there a chance there's something wrong with the device itself?
Thank you very much!
Common problem.

Return the battery.
The seller store the battery in a very poor way.
Lithium should be kept at around 40% charged if you store it for a long time (more than 1 month)
I have 5 batteries with me, 3 of them are considered broken (70 - 60% left)
The last 2 are still in very good condition, around 98 - 99%
About your device, you will need around a few days of charge cycle with a good battery.

Thanks for your answer. I didn't know batteries for this phone are so problematic.
I just charged it to 100% slowly from my PC, will use it normally and see how much the battery lasts and if it shuts down again. As I went through forums, some people say I need to do battery calibration. If it's still bad, I'll return it.
Thanks again!
Try to get a battery direct from Samsung. Failing that buy a PowerBear or Anker. Do a factory reset and calibrate your battery by fully charging it, then running it down to 0% (if it shuts down, keep turning back on until it won't turn on). Then charge fully back to 100% again - DO NOT USE FAST CHARGE.

I will look for a store somewhere. I don't think I can find those two brands here.
I did a factory reset when I bought it a few days ago, but that was with the old battery. Will do the factory reset after I drain it to 0% later today.
I don't have a 'fast charge' charger, and I have it disabled in settings.
Thank you for your response!

What I said before is for all phone that uses Lithium Battery.
Lithium Battery must be kept in a storage at around 40 - 80% charged & must avoid hot places if you don't use it for a long time.
Draining Lithium Battery to 0% will deteriorate the battery faster so it's a big NO.
Calibration is done on the phone not the battery.
Delete "batterystats.bin" to calibrate the battery gauge.
Calibration is useless if the battery is bad (you received it at 0% it means that the storage condition is bad thus the battery is bad.
Charging from PC is a BIG NO as USB port on PC only provide around 500mAh & usually it's unstable.
The charging rate is too low & it could deteriorate the battery faster too.
And the last....I think factory reset doesn't necessary reset the batterystats.bin, so you have to delete it manually if you are rooted or follow this link if you are not rooted.

Hi, I didn't return the new battery after all, I think it 'calibrated' itself after the first charge. Also it goes from 100% to 1% and shuts down properly now.
I did two tests on full battery:
- barely using it, no wifi, data etc, just a few short calls (probably 30 mins of OST) and it lasted almost 6 days
- stress test, wifi and data on, gps with maps and waze on, maximum brightness and and a very long youtube video playing constantly (screen on) and it lasted about 5 hours and 30 mins
In normal use it lasts me about 2 days, but it slightly worries me that if I keep mobile data on all the time it only lasts until the end of the first day.
Would this be considered a good battery life for the Note4?
Thanks to everyone for replying and helping!!
