I feel pretty bad since Ive been bouncing around this forum asking questions about the root process for my friends Nook Tablet like there's no tomorrow. But Unfortunately I have yet another question about the Nook Tablet. I've done the Rooting process thanks in large, if not completely, to digixmax. But one thing Ive noticed is that the battery seems to die pretty quickly. Unfortunately I didnt take a moment to play with it before rooting, so I don't know if the battery was just getting old, or if it's because how much the CM11 Kitkat Rom is taxing the Nook Tablet. Either way, I explained to my friend that the battery may not last as long because the Nook Tablet probably wasn't exactly design to have all the features/functions of KitKit. She looked into battery option yesterday and cam back with this:

Does anyone know if the NewPower99 batteries are any good? And would it power the Tablet longer than the current factory battery?

I realize this is a old post but I thought I would chime in on it. I have done a lot of research lately as I have a battery issue. Well it is a problem with phantom touches when the battery gets to 23% or so. From all I have read this is a battery issue. At first I was thinking it needed to be calibrated. However after digging though all the information, most battery calibration methods just delete the battery stats. This apparently is only data since the last time the device was charged, and not long term information that affects calibration (confirmed by a Google engineer). I did read about one other file to delete in \rom max#### if I remember correctly, and that might do it. I may try that soon.
The only other method I saw was to charge it full, run it down till it shuts down, charge it till full, turn it on and let it sit ON for 30 minutes (set screen shut down to 30 minutes), then plug it in to charge full. With some Android devices this can recalibrate the battery (which makes sense), but not sure if it will work on a NT or not. I am going to try it though.
But back to the battery, I did like the look of it and the video they did. I may purchase one from them if all of the above methods don't work. Someone else got a 3rd party battery from another company and said it worked well http://forum.xda-developers.com/nook-tablet/general/changed-battery-nook-tablet-t2829771 it is the same capacity which IS less than a original NT battery (3200 vs original NT at 4000) so you won't get the same runtime that you would with a brand new NT. That said all LI-ion batteries degrade with age, so even if you happened to find a new unopened device, the battery would not quite be the same as when it was released. Also while you can get batteries from say Ebay, you do not know how many cycles or life is left in them. Could be a few days, a few months or years. Even if they say 80% of the capacity is left in them, that is approximately what you will get with one of the new batteries anyway.
The one company is cheaper than the other (20 from batteryship.com vs $40 from newPower99) and they are the same capacity so I am not sure which one you would want to go with. As far as presentation goes, Power99 wins with their nice video on you tube and the look of the battery itself. Both seem to include the two tools necessary to do the battery replacement. So again up to you which way you want to go. Both have 1 year warranty. One thing about newpower99 they will install it for you for $60 http://www.newpower99.com/Battery_Replacement_Service_for_Nook_Tablet_p/nook-tablet-pbr.htm I can't vouch how well they do but if someone is really worried about doing it, then I would say let them do it instead.
Personally though I would just do it myself. But I did just find this on the newpower site "•Opening an electronic device and replacing the battery does entail risks to the functionality of the unit. NewPower99.com does not guarantee the overall functionality of your unit after battery replacement service. You acknowledge these risks and understand that NewPower99.com's maximum liability is limited to the cost of the battery replacement service." Which doesn't instill confidence in sending it to them lol.

[1st post] Apologies if this has already been discussed in a thread -- if so, just shut this one down...
Though I am looking forward as much as anyone else here to eventually getting my own Asus TP, I am curious about how easy/expensive it will ultimately be to replace the internal battery i.e. when the initial one wears out from continual drains and re-charges (as a follow-on to this, I am curious what treatment needs to be given to the TP battery to maximize its life span)?
One of the many selling points of the Toshiba Thrive was the user-replaceable battery (and easily-removable back panel). From what I understand, that was the *only* tablet with that feature.

You won't be able to change the battery easily. From what i looks like I guess the back is somehow glued to the screen, so I don't think removal will be a good idea
Modern batteries should not need replacement before the average user buys a new tablet, so i wouldn't worry about it.

Hmmm...it disturbs me to think that it might not be easy (or, worse yet, possible) to replace the battery in *any* device that I might own. Even if I myself cannot do the 'replacement', I would hope that some service center could (?). If not, I think it is crazy to 'throw away' a perfectly good device just because of the battery. I suppose one could just leave the device plugged in, but on a tablet that is very constraining
Any estimates for how long it might take to get to the 'point of frustration'? Say, heavy use for a year? 2 years? Hmmm...
Nothing is impossible, it will just need to be disassembled similar to the way the ipads are imo, modern lithium batteries should be able to easily go 2 years of heavy use with no issue.
Apple doesn't allow users to replace batteries. You must send iDevices back to the all mighty to have batteries replaced. Im sure Asus offers the same thing.

If it is a permanent location, then it should have a permanent power source, which means you wouldn't need to run off the battery while using it.
I realize that this an old thread, but I found it while googling and I just want to post a reply in case anyone else comes along.

In it, you can clearly see that the Asus Transformer Prime is very parts replacement friendly. You can replace just about any of the internal pieces, as long as you can figure out how to open the case without damaging it.

Thanks for the video link! Now, I hope things are just as good -- if not better -- with the pending 'Infinity' model
honestly because the battery can last for days without a charge, it cycles much less than say a cell phone. I charge my tab about 1/4 as much as my cell phone with an extended life battery. (Granted overall the phone gets more use) but still I think you can expect at least a good 3-4 years of moderate use before even THINKING about a battery change. For someone like me who uses my tab in spurts depending on the situation I wouldn't be surprised if I have only had about 100 cycles on the battery so far and I've had it 6 months so far.
How did you glue the battery? I used double sided tape but didn't immobilize the battery. Did you use a specific type of glue?

How's your battery doing these days?
Lol, I know it's 2019, but I still have my Prime.
I am also looking for a battery replacement. I mean it is pretty much the only reason making it "old", otherwise it is still very usefull and can always be used as a photoframe if needed
Anyone have any knowledge where a replacement can be found?
I'll take the glue off and reseal it if needed.
Hey!
I know that it's never a good idea to leave full or empty batteries just stay without use for too long. I don't use TF201 every day and I have it shut down when I don't use it, I am wondering how the battery should be managed and if any of you have any experiences with maintaining your previous devices, like TF101 or others, in similar conditions.
I charge the device after use and then it stays that way a day or two without use due to me not having lectures or enough time off work to play with it. When I do play with it, I don't use more than 20% of battery life and then I dock it with keyboard again (which charges it again even if it is turned off, which is really nice).
Are there any bad side effects of having the device powered off and not used for a day or two? Or letting the keyboard charge the device while it is powered off? Or leaving it in charged state for a few days?
Since I cannot change the battery on TF201, I am super OCD about the battery situation to make sure it works properly throughout the ~2 years I'll be using it.
Thanks!
I let it drain completely then recharge it. I don't power it off, just let 'er sleep in between work, driving, eating, etc.
Moderate usage will give me a couple days worth out of it. Charge during sleepy time, wake up, disconnect, repeat.

Really good article, thanks!
Problem is that TF201 is a special puppy, since its dock recharges the tablet even when tablet is shut off. It's not recomended to keep the battery 'full' nor 'empty' and problem with TF201 is that it keeps tablet full or drains the dock while keeping tablet full, even if tablet is shut down.
I am just wondering if this behavior is bad for battery life in the long run if I don't use it for a few days (I certainly won't keep it 'on' for days and not use it, this will certainly make it go through more recharge cycles in the long run).
That article is good for managing a single-battery device, but since tablet with dock takes over a lot of charge-or-not decisions, it's a little different.
It's basically question about which is worse, going through definite amount of recharge cycles quicker because it is on and needs to be charged every now and then or letting it shut down and used when needed like a laptop.
Maybe I'm thinking too much and it doesn't really matter, but it just made me curious since I never had TF101, so I can't really rely on that experience.
We can buy the TF201 battery, can't we?
If yes, I don't think you should worry much.
Within a year or two, the battery should be still in perfect or near perfect condition.
If not, then buy a new battery.
By that time frame, most of us would have been buy a new tablet anyway
Make sense? no?

TF201 battery is not user-replaceable. It needs to be done by ASUS or you're breaking warranty. I don't even think ASUS will sell these batteries.

Ok, thanks for the info, I did not know that.
But still, if I have a tablet, I won't keep it for more than 2 years most probably
And on my experience, for two years, battery will still be good.

Yeah, possible. I'll shake that OCD'ness off me then I suppose. I've just always had user-replaceable battery Android devices simply because I don't pay attention to how badly I mistreat the battery, I can always replace it. But with TF201 I have to pay some attention
Is there a way to signal the keyboard dock to start charging only when the tablet has 20% charge left?
I leave the dock connected all the time and the tablet is constantly being charged by the dock.
the lithium ion battery is fine you can let it sit for months and months, you can charge it every 5 minutes, you dont have to let it drain out or manage it just let it do its thing!
I've had my Flyer a few months now and in the last few days the battery seems to be draining very quickly. I charged it full again last night and this morning it was at 88%.
I've turned everything off so just the bare bones of the device are alive and i'm using Juice Defender, and still no joy. It's only started doing this in the last few days so i presume the battery is on the way out very quickly.
I've let it drain to 10% and charged it, and it's made no difference.
I'm not going to mess about with settings and more waiting to see what it does etc...., I really just want to get a new battery and be done with.
Where can i buy a new battery? I've had a look on fleabay and no joy.
Any suggestions where to get one, part no. etc...?
Many thanks in advance

happened with me also....10% battery drained overnight...
what app is using most of ur battery?
sometimes push service in some free market apps drains a lot of battery and it keeps running even when app is closed... check running processes... well i uninstalled that app with push service and all became normal
Thanks for that but i've had a look through and it would seem that there isn't anything happening over night that i'm not expecting or that is being very hard on the battery.
I'm pretty confident the battery is the culprit here. Sourcing a new battery however is proving to be a problem. Somebody somewhere must be selling them.
I've just been on to HTC in the UK, they have a service centre not very far away from me and they won't sell me a battery or even give me a part no. for the battery.
Come on, somebody must know where to get one.
I think i might have found somewhere in China...
Battery - BG41200
3.7v - 4000mAh
If the prices were cheap enough how many of you would be interested in buying a battery for your Flyer.
Perhaps do a group buy?
i thought flyers battery is not user replaceable?
It's very replaceable and easy to do.
Here......
http://www.techrepublic.com/photos/cracking-open-the-htc-flyer/6256123
I'm going to have to look at getting a new battery sooner or later. It's getting to the point hat the battery is always running low by the time I get home in the evening or even running out. With pretty much the same use it used to be good for a day and a half easily. Flyer was purchase may or june 2011 so it really needs to last another 16 months or so.
Well......I ask again. If anyone knows of where to buy an internal Flyer battery please post a linky.
I posted this thread earlier today
"I just wanted to know what people are getting out of their batteries. I unplug mine around 7:30 am when i leave for work. When I get to work i turn on my wifi (rooted thunderbolt) and leave that on all day. I have the setting to turn wifi off (flyer) when screen is off. When I get home around 5:30 i switch to my home network and by 8-10 my battery is pretty much gone. Is this normal battery life or are there any tricks I'm not aware of that will help with battery. My wife has an Ipad 1 and she seems to get days of use out of it before she needs to charge it.
Also, I don't watch movies or video at work... most of my use is surfing, twitter and email."
I'm trying to figure out if what is normal battery life and If mine came with a bad battery. If so Yes I would be interested in getting a new one.
The Ipad battery has much longer life and is a much bigger capacity battery. The new HTC Jetstream also has a much bigger capacity battery as well. I think HTC have learned lessons on how much battery power these flyers use, but unfortunately have used Flyer owners as guinea pigs, rather like the first Apple iPhone but that had terrible battery issues as well although they've gotten better over time.
When my Flyer was brand new the battery lasted for ages and i couldn't understand what people were on about the battery not lasting for very long. So up until a few weeks ago my battery was doing fine and then almost within a day or two the battery started to run down quickly and has been doing so ever since. I've since loaded/unloaded new ROMS and done all the usual procedures for deleting the battery stats etc..., and still no joy.
I think the problem is with the battery not being man enough for the job at 4000mAh, and the drain is such that the battery is being worked hard since September last year (in my case) to a point where it is now progressively failing. I'm not so sure either that it's all that good in terms of quality.
Most of that time it has been charging from one source or another. If my Flyer isn't in the car or in the house it's not often being used battery only unlike most other people probably use the battery only a lot, so i can't understand why the battery is failing when it's not even that old.
This is a big issue with the Flyer and for what the device cost i would have expected a lot better. I think the Flyer in itself is a fantastic piece of kit that i will no doubt keep for a very long time as i did my XDA IIi but i never had problems buying another battery for my IIi. HTC will not sell me a battery, they insist i send the device to them and they will swap it but will cost about £50-£60 for the pleasure. I flatly refuse to pay that!!
What is required is a bigger capacity battery (6000-8000mAh) in the same packaging as the current battery however, i think for now i would happily settle for another of the same battery if i could just get hold of one.
So far it's proving an impossible task!!
Just to add: Once you've made sure there aren't apps being opened at startup that don't need to be opened until you're ready to use them, also make sure wifi/bluetooth, mobile data is all off when not required, and all the usual tweakes to make sure animations are off, screen is on the lowest brightness etc..., then there is not a lot more you can do. I don't know how much use something like Juice Defender will be as that only makes sure your data connections are off at night and other times you specify. I've tried it and it didn't help at all so i don't know what else to suggest apart from turning the radio part of the phone off completely at night if it isn't on charge.
If i leave my phone off charge all night, having fully charged first, i wake up in the morning and it's down to around 86-88% battery.
As most probably know, ever since 2.2 was released, motorola phones refuse to work with aftermarket batteries (even if they worked just fine on 2.1). I've spent hours searching the net, tons of people with this issue, but haven't found a single solution. Everyone just gives up and buys an OEM battery (while I don't mind paying a bit more for one, I would like to use the 2300mAh model I bought... assuming the extra capacity isn't a straight lie).
Has no-one been able to solve this yet? No patch that removes this greed-driven move by moto?
+1 I wonder of someone could calibrate drivers/hardware to make the os see past 1930mah batteries. My 4800mah battery goes uncalibrated until then
You mean to say your monster battery actually work? As in, your moto at least accepts it (allows it to charge)?
Yes however... it will work from dead to charge to like 3.8v (100%) and continues to charge till 4.205v then drain to about 3.7-3.8v its at 1%. I can continue to use the phone till the battery is at 3.3-3.45v and its dead. Something about the onboard if chip that makes for no more than 1930-2300mah on the "recognized/actual" current values. This makes for no more than half of your battery from 1-100% and rest is looking at voltage and guessing last half till near bottom voltage to guess where/when it might die. I have a post. Google "4800 Mugen atrix battery xda" its post number 1.
you'll see what I mean.
Hm... some more reading seems to suggest that SOME aftermarket batteries are OK, like Mugen. I would guess they paid for authorization by Moto. One other post claimed this isn't happening for all providers, but I suspect that just a case of staggered OTA rollout times.
I'm having a hard time believing there isn't more interest and work on this issue. It strikes me as the kind of thing that would raise alot of hackles in an open source community especially. But so far every thread I've seen ends with the person just giving up.
Does your Nook go crazy when the battery gets around 15 percent? Mine will start opening and closing applications and then it will shuts down. You would think it would warn me ahead of time
I ran into this phenom several times, some with battery-level readings at even higher values in the 25-30% range.
I think part of the problem is the battery-level readings in many CM builds are not reliable: I've seen battery readings jumping as much as +/- 10 points immediately following an update to a different build -- hence there is a good chance the real battery level might not be where the reading says it is.
I thought that the accuracy on my build may be off. Guess the best think to do is put her on the charger at 20 percent

I don't think it's related to CyanogenMod. I recall getting this wonky battery behavior even on the original B&N operating system. I don't have the problem any more, but I've done so many tweaks to my Nook that I couldn't tell you definitively what did the trick. Mine will happily tick down to about 3% or so, then shut off calmly. You can try flashing one of the kernels that Demitrius has posted in the dev forum; that may help. I'm running his Nook on Fire/Showtime kernel with great success.
Of course, I do need to say that one of my tweaks was ripping out the old battery and replacing it (which happened about the same time last summer as flashing Nook on Fire, hence not being sure which fix did the trick). There are guides on YouTube to replace the battery, and you should be able to find a new battery for $30~$35 US. It's not technically challenging, but it is difficult -- everything inside that tablet is gummed up with adhesive, and you need to take great care to make sure you don't damage the case or the screen while you're pulling the old battery out.

I agree that the problem of "NT going bonky at low battery" is independent of ROM version.
But false readings of "battery remaining capacity %" in some CM builds make the problem seem to occur at a higher battery level than actual.
Mine also started going crazy about a year ago when the battery got to around 17% left, this was on the original (rooted) B&N firmware, then about a month ago it would start going nuts when the battery was just below 90% full (still on B&N firmware).
I found that if the brightness was high or the CPU load was high then this made it worse, I used to use it a s portable wireless video player quite a bit and discovered I had to put the brightness to 50% or lower to try and stop it going nuts. Now it's so bad I leave it plugged into a power source all the time to use it, which has effectively killed its portability.
I have put CM 10.2.0 on it recently but that hasn't made the battery/touchscreen problem better or worse, except it can no longer read TF cards
Where did you get a replacement battery? That might solve the problem for me also.

It would seem that I also have this problem. I have rooted via the method at http://forum.xda-developers.com/showthread.php?t=1439630 I haven't installed many apps so I don't think that is the problem. I only rooted it last week, spring pad went down and Evernote only supports Nook HD for some odd reason from the B&N App store. I installed Evernote, Firefox, Tor, and the Tor browser from Google play/market. It only started doing this last night, at first I thought perhaps it was a virus or something. Then I realized it happened when the power got around 23%.
It just started doing this last night. The only other thing I did was update the NTHiddenSettings app via Google Play. Thinking that was it, I reinstalled the previous version but nope no difference. Other than what I have listed this NT is stock.
I did find a great battery removal video (and place to get them) at https://www.youtube.com/watch?v=3F0glSyvj2s I hope that is not the case as I really don't want to buy/replace the battery. But if need be...ok. I really like this tablet and it does all I need.
If anyone has fixed this (besides a battery replacement) please do post. Thanks.
Oh I just found on another forum someone posting about battery calibration https://market.android.com/details?id=com.nema.batterycalibration&feature=search_result which sounds like it may be our problem. Something messed up the calibration would certainly make our NT's go crazy. Anyone ever try this?
UPDATE:
After digging around I found that the battery calibration app in question doesn't do much other than delete a file that is deleted anyway as soon as you plug in your tablet and charge it. So that is not it.
And on another note with the "spare parts" app the 'battery history' option errors with "the application spare parts ) process.com.andriod.spare_parts_ has topped unexpectedly, please try again." Is this normal? It is version 2.3.7. NT Hidden Settings app application settings/battery use works fine and shows the amount of everything that has used the battery since it was last plugged in/charged. Could this error be a sign of the problem with the phantom touches and inaccurate battery display? And if it is a sign of something broken, what and how do I fix it?
This problem recently got a lot worse on my (nearly 3-year old) NT -- random opening/switching of app screens now occur at battery readings in the 65-85% range (used to be ~25%).
I contemplated replacing its battery, but with the cost of the replacement battery ranging from $22 (on eBay) to $40 (from New Power 99) and the risk of messing things up during the replacement process, I opted to simply trade in the NT for $30 of credit (trade-in offer valid till 01/17/15, see http://www.barnesandnoble.com/u/tra...FILIATES-_-Linkshare-_-TnL5HPStwNw-_-10:1&r=1) toward a new Samsung Tab 4 Nook on-sale (in-store, ending today 12/21) for $129.
FWIW, when restoring the NT to stock ROM (for the purpose of the trade-in inspection at the store), I noticed that the battery reading in stock ROM is ~20 points below the reading shortly before while running CM.
