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.
Some say let it drain all the way, then fully charge...some say don't let it drop below 50%...i tried searching, but couldn't get solid info....so what really is the best way to charge a battery in order to get maximum battery life? thanks
Lithium ion batteries shouldn't be fully discharged on a regular basis; they prefer partial charges. It's useful to fully discharge occasionally however so that the phone knows the full range of the battery's charge states or the battery meter will be inaccurate.
It might be better to discharge to some particular level than another, but that's impractical. Best practice as far as I'm aware is to charge whenever possible. At least we have user-replaceable batteries if they do start to get weak!
Yes, 20%-40% drain is ideal balance of long-term battery life and not changing too often. Of course, the lower end of this would mean about an hour of use if you have the display on the whole time. So, best thing for the long-term life and ability to use your phone cord free is to own 2 batteries and change when possible.
I don't even bother to "calibrate" (run the battery down 100%) because I switch it often enough and I don't need to know if I have 40% left instead of 55%. If I have high use or only one battery on me then sometimes I'll let nature run it's course, but I never go out of my way for it.
Well in all honesty, I have to say that I've been doing the complete drain and full recharge for about 5 - 6 cylces since I got the phone about a week ago. Furthermore, I have set my autokiller to aggressive and I've seen a big improvement in the battery life. i.e. from 23 hours to about 1d and 20 hours.
So up until today I've been having fairly lousy battery life (understandably) its dual core and h+..its expected..
But I read a thread earlier today (I forgot who, sorry) suggested that you go into the Latitude application and disable it and log out - ever since I did that this morning my battery has been absolutely amazing with the same usage.
It was 16 hours since unplugged from it's AC charger still at 40% which I think is amazing..just wanted to share that with you guys and suggest that you try it!
*Clarification: I normally get 12 hours and it's dead, today with the same usage I got 16 hours and 54 minutes with 40% left
Sorry for the bad grammar I wrote this in a rush
I got similar results from letting it die and get a full charge. From 10 hours to a day easy.. This thing is seriously on steroids.

Lithium Ion batteries are different to their predecessors in that they have no "memory effect". Other, older battery chemistry types had to be fully discharged before charging again for them to be effective and hold a charge. Lithium Ion batteries will not benefit from discharge, and are in fact ruined if you let them completely discharge. If it's a protected battery type it should shut off before it is fully discharged, thus not ruining it, but there is still no benefit. They are also very sensitive to temperature, and heat will kill them too. They will degrade at a much faster rate with heat. These are the two main reasons we have to replace cell phone batteries so frequently.
One annoyance about this phone is that it won't charge from usb worth a damn.
My previous phones I would let "slow charge" off a old powered hub overnight. With the Atrix you pretty much have to use the wall charger which charges much faster.
I swear I got better life out of my old phone when I charged it this way vs the fast charger.
Mine charges fine with USB from my laptop. I get easy 12-14 hours with 30-40% left depending on usage.

Don't get your point!
Lithium Ion batteries do not change their chemical make up for Android, Linux, or any other operating system for that matter.
Android "battery stats" have absolutely nothing to do with how a lithium ion battery operates, and is designed to operate. I would love for you to enlighten me on how Android changes this, as your post seems to imply Android can manipulate the chemical makeup and basic design intent of lithium ion batteries!
Protected lithium ion batteries have "protection" circuits in them much like a mini computer which can be programmed to shut them off prior to full discharge, over charge, too much heat, etc. Android can utilize this "mini computer" to prevent problems with the batteries themselves, but not eliminate those problems!
Now, if you really want to argue this, stop quoting Google, (which you actually didn't, you just said Google it!) and we will dig into the full design intent, chemical balance and makeup, and actual results of tests which come directly from the engineers who gave us lithium ion batteries. You can produce your test data to substantiate what you are saying, and I will do the same! If you aren't willing, or can't as I surmise the case will be, stop Googling, and stop jumping up and down because someone has commented something contrary to what you believe or have said. I simply pointed out FACTS relative to lithium ion batteries so people wouldn't be confused thinking the best thing to do is let the battery drain out and then charge it, because if the battery doesn't have a protection circuit, it will die!
<edit> BTW...........If you seriously want to argue this, don't comment back with something childish like a WiKi link............lets get down to the nitty gritty nuts and bolts of this subject!
btw I am at 40% .. 26h 06m 02s since unplugged
1day 10 hours 33 minues 39 seconds since unplugged,
30% left
just plugged in
I'm currently at around 46 hours with like 25% left lol. I guess that's pretty good!
Obviously I'm not having too many problems battery wise, but I was wondering, how do I disable this latitude application? When I click on it in my app drawer, it just takes me to maps... However, I installed GingerBlur, and the latitude app isn't even in my drawer anymore? Is it just an add-on of sorts to the Maps app? If so, if I've never actually signed in or anything does that mean I don't need to worry about disabling?
If you can deal with the lagged connection after unlocking and periodic checks for stuff like email rather than near instant, then JuiceDefender really does seem to go a long way in terms of battery saving.

Caelan I'm not trying to be a **** or argue about liion batteries, I know that draining it affects battery health. What I'm saying is that I read back in my n1 days that theirs a way to enter "learn mode" from plugging in your phone while the shutdown process (chimes, and the "shutting down phone") note this was all from xda and all for the n1 so I have no idea if its as simple on the atrix. I was going to attempt this but I fell asleep and it completely discharged and on the next charge it has calibrated itself and I'm experiencing much better results.
I know its not placebo because nothing has changed usage wise. Same apps same deal.
I only told you to google it because thats what I did and I can't remember what article. Cheers
** on a side note I did this on my xoom because I was having problems with bad battery after using oc kernels and continual bad battery after flashing back. And I can report 3 days uptime so far so theirs something to this.

And yes I agree that if you are simply a power user and you have a lot of weak internet connections and run your screen on full brightness you will experience very little affect from calibration but if your a moderate user that is having problems getting your phone to sleep properly and still getting 10 hours then something is wrong.
No android does not chemically change batteries but it does control how much juice is used for certain activities. I noticed that my battery would drain rapidly from 100 to 60 with little usage and having my screen off didn't seem to slow it down. From 60% it would be better but at the 20% it would take a long time to drain. After I calibrated my battery it drained only with usage and would practically stop if the screen was turned off. Hopefully that can help someone... I know how annoying an unconditioned battery can be.
Ps what caelan is saying is true so if you do calibrate don't do it often because this leads to shorter battery life in the long run.

I run gingerblur 3.5 on my atrix and it more than doubles my battery life over stock. Just plugged mine in and was 1 day and 23 hours since last plugged in. I don't do a lot of stuff with it besides text and try not to have a TON of apps running.

Right now I am at 1 day and 10 hrs @ 40%.
Download Elixir and load up a 7x1 widget on your home screen. add in Wifi and GPS switches. These will save your battery life the most.
do any of the users that get well above 16 hours of battery life want to elaborate on what applications may be running, widgets, etc? I have my brightness set to 11%, have 5 homescreen pages, mostly widgets that refresh hourly or longer, and hardly ever have wifi on.
basically you had your gps reporting your location all day long. No wonder you got a lousy battery life. You should have seen the gps icon on and the app being listed on the battery manager.
Just wait till exchange corporate sync goes nuts and drains your battery in 3 hours flat.

Didn't find a main thread for silly questions such as this so hope it wasn't wrong for me to post this here, but I currently find myself in my phone going as low as 50% on a daily basis and I charge it next day at not lower then 40%, will this wear out the battery? am I really supposed to charge it when it's really low? Thanks.

The latest in Li-ion batteries, as the one in our phones, one duty cycle is when you use 100% of the charge.
That is ifyou go from 100 to 0 that's one cycle.
If you go from 100 to 50, recharge and again 100 to 50, that's one cycle.
Batteries wear out depending on the number of duty cycles. More duty cycles, more wear.
So what you are doing will not wear out the battery.
Also I'm not sure about this, but it is recommended that newer batteries should not be completely discharged.
Please correct me if I'm wrong, anyone else who can confirm.

Modern batteries are not like older (10 years+) batteries. I'm not about to write a wall of facts here etc. etc, but I only have one thing to tell you:
Use your device, and don't worry about the battery. It'll do just fine until the day you decide to buy a new device. Now stop worrying and just use it.

Same here, these batteries are tough. I am anal about my phone battery being charged. Haven't had an issue for years and I expect the same performance out of my S7E
Topping up your battery before it is fully discharged is the best way to extend your battery life. Modern batteries run best between 40%-80% charge. Minimize the number of times you fully discharge the battery as that is more likely to wear out the battery, although it is ok to use it until the phone shuts off once in a while.
Very impressed with the battery of the S7E. I charged to 100% last night and didn't charge until just an hr ago and was at 47%. Normal use in the morning til now. In n out of meeting, so its doing its job.
Now back to the topic of this thread, i've read some say these newer batteries should be power cycled at least once a month. Any one recommend that or against it? Haven't done it myself but did it a few times on my iPhone 6 Plus and that thing had an awesome battery even though its actually smaller than the S7E. Thoughts???

I've seen it recommended as often as once per month or as infrequently as once every 3 months. The general consensus is that it can be beneficial in that it can correct any issues that the phone software has in determining the battery's capacity, not that it is actually helping the battery itself.
Yup, I did that once in a while with my previous device (a Sony), and the battery on that one is still very good after nearly three years. I wouldn't do it that often though, but it's useful to do it when you notice the battery meter hangs on the lower numbers (like if 10% hangs for an unusually long time) or you've just flashed a ROM. The OS tends to get a little confused after some time, so it's okay to do it to "calibrate" the system again.
Thanks for the helpful replies guys.
Draining a Lithium battery to zero is one of the worst things you can to an Li battery. Don't do it. Period. Ever.
Yes, don't power cycle a battery. It MAY help give a more accurate battery reading, but it's messing up the longevity.

Hi all,
Recently I have exchanged a battery at a local service provider, battery they showed before installation seemed as legit as they come and after replacement phone felt way more agile especially at a lower battery charge levels. So I was happy until I started investigating poor SoT that I thought at the time was due to the Oreo update. After some time, resets and reinstalls it feels like the system is as healthy as it can be for now, but Accubattery shows 83% health at 2,853 mAh out of designed 3,450 mAh. That is only after few charge cycles, but I am still worried that it might a permanent battery hardware issue. Right now at latest Oreo build with elementalx kernel running a wingoku gov profile I get around 3 to 3,5 hours of SoT with little use, over night after 100% charge phone looses around 10% percent by the time I wake up.
If anyone has any insight into similar issues and can confirm Accubattery health stats credibility I would really appreciate.

Sorry, but you got a bad replacement battery. It happens. Although it just provides an estimated value, I've found Accubattery to be a very solid indicator on the phones I've used it on. Since your battery is barely above 80% it takes the guesswork out of the equation. The battery capacity estimate converges quickly to a value after only about 3-4 charges. That's it. It's not something else with the phone. It is the battery itself. There are literally dozens of threads discussing which batteries are good replacements and from which sources. Buy one of those and your problem will be solved. There are some Accubattery haters out there, but I guarantee based on what you are saying, your battery is a dud. With a fresh, high quality battery you should be seeing very high 90's to low 100's. Yes higher than 100% because some batteries sold actually have a higher capacity than rated. Try to get one of those.
Thank you for a reply.
At this point I guess I will just have to live with it until I buy a new phone, I only decided to give this one another go since I love it and do not see anything on the market now that would appeal to me as much as 6P did at purchase. But I do not want to spend more money and time on this, just wanted to make sure this is not a software issue. Software I can tweak, but battery replacement yet again is too much.
