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.
I found this article very interesting on batteries. Debunked alot of myths surrounding the type of battery we have.

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 use my Gtablet all day and I always shut it off and turn it back on ( boot it up) and ofcourse that takes 2 minutes or so.
Will it do any harm (or kill battery etc) if I leave the Gtablet on all the time like a pc ( maybe re-booting once a week or so) and just hit the power button to shut the screen off. Just dont want to kill my device by leaving it on all day and night. Just curious if anyone does this and if theres any harm to the device.
Thanks.
It will drain battery faster, so you will have to charge it more. That will probably reduce the life of the battery as well, since it will have more cycles.
I do the same as you, turn it on when I first use it and shut it down at night. No reason to drain a battery overnight, IMO.
Forgot to add that I leave it plugged in and charging all the time until I use . But yeah I guess turning it on at night and shutting off before bed is not a bad idea.
Thank you.
I've been confused by this situation, becuase when I first got mine, I made the opposite comment and was made too look like an idiot.
There was a post a while ago regarding how to get better battey life. People were complaining that their G-Tablet would lose too much battery life when left in sleep at night (not plugged in) I made the comment "Why not just turn it off?" and people responded with "Because it's a tablet."
Having NO IDEA what they meant, I asked what they were taloking about. Basically they explained to me that a tablet should be treated as a cellphone, not a computer. "You don't turn your phone off at night, do you?" was one question asked of me.
I'm still lost, becuase frankly, I think that they were just being stupid. The tablet IS more like a computer than a phone, as far as battery drain goes. I'd be in a world of trouble if my battery only had a 10 hour drain while in standby.
SO, I turn it off, and leave it plugged in at night. I use it all day, then plug it in (while on) in the evening so that I can access it if needed. Then, before bed, I turn it off, and just let it charge all night. occasionally, I will leave it plugged in an on at night. I figured that's what I do with my cell phone too, right?
Leave it on, all the time.
My wife and I both leave ours on, all the time (well she has too because it will not boot once turned off unless I nvflash it). There is no reason to turn it off unless you have to have longer than a day for battery life and are opposed to charging it every day.
I take it off the charger at 7:00am when I leave for work and then put it back on the charger later that night. Depending on how much I used it (were lots of apps updated, did I run another titanium backup, etc...) determines if I need to plug in earlier or not.
My wife leaves hers on the dock and takes it off to use, then places it back when done.
To help with battery life though you can set the screen timeout to a low time...so once you stop using it....the screen will timeout quickly and put the tablet to sleep.
Here is my very uninformed opinion on this debate.
The PC is designed for you to turn it off when you're not using it. The phone/tablet is designed to be on all the time and just be put to sleep when you're not using it.
The first sign of this is the OS itself. In windows and mac platform, once a program is running it will continue to run and run and run like that annoying rabbit until you stop it. And if you leave those programs running in the background they will do nothing but eat up your memory. What you then have to do every once in a while is to reboot.
In fact, back in the first gulf war there was an incident where a computer controlling the anti-missile defense system of a base was left on too long. They kept leaving it on because they were worried about incoming missiles. When the real missiles came flying, the system had already used up all its memory and made inaccurate calculations to counter. I think a few people died as a result. The incident could have been prevented if they had rebooted the computer. I remember reading about it back then.
Anyway, android is designed for your phone, which is meant to be on literally all the time. Especially with froyo and up, there are built-in systems to shut down running apps that aren't being used. Memory cycles also act differently so you don't run out of memory the way you do with PC.
Another thing is there is such a thing as turning it on and off too much. A significant determination of the lifetime of your electronic devices is how many times you turn it on and off. Not only that, The lifetime of your battery (how many cycles of charges you can have) also depends on the age more so than the actual number of times you recharge it.
You can very easily experiment with this by buying a brand new camera battery and just let it sit there. After a couple years, even though you've barely used it, you could only get less than an hour (sometimes even much less) even though when you bought it it's suppose to last your camera a whole 3 hours with a full charge.
That said, I'm running calkulin+clemsyn combo with cpu master setting the speed to 1.0 ghz most of the time. It's only when I want to impress people do I put it up to 1.5 ghz. I've tried both methods. For a couple weeks, I would turn it off every night and on every morning. Then for the next couple weeks I've been keeping it on all the time and only putting it to sleep while docked at night.
And I know this is only anecdotal evidence and is perhaps meaningless in science (I'm a researcher) but the gtab appears to be working a lot smoother and better when left on all the time.
Just my 2 cents.
It's a tablet, by design it suppose be turned on and be ready to use in no time at all when you fancy to dig up internet or watch movie, netflix etc.
The one way to achieve such readiness is to never shut it down. But from other hand, why waste energy when not in use.
So, here we go with "sleep" mode which is by the way implemented in Android 2.2 and 2.3 very poorly (in comparison with iOS). gTablet with Froyo, GB would typically loose 0.9-1.5% of charge per hour "sleeping" and then again there might be runaway apps which stuck in endless loop and will kill your battery in no time.
I've tried lot's of things and nothing can bring down discharge rate in "sleep" mode less then numbers above. So, I just keep my gtablet charging overnight.
Sometimes I just shut it down. Especially, when I found the way to speed-up cold start from 2 min. previously down to 40 sec.
Thanks all very informative and appreciate all the opinions.
I turn my gtab off at night but charge it only when necessary. I never use it while plugged in. I don't see the parallel between gtab & cell phone since I've not missed a call on gtab
My tablet is never turned off, unless the battery dies.
Part of the whole point of the tablet paradigm is the instant-on/instant-off concept. Remember, putting it to sleep uses very minimal amounts of power. Most functions go into standby, its a lot more than just "screen off". If I don't use the tablet much during the day, it can easily last until the next before having to charge again. Putting it into airplane mode and leaving it on all night will probably not consume that much more power than booting it up again in the morning (remember, when the CPU is being used it consumes more energy. Booting up is intense, sleeping is not).
Heck, I heard HP was considering leaving out the ability to power off their WebOS tablet (coming from the world of Palm, where many devices did not have the ability to shut down completely).
Stop comparing it to a computer- they aren't exactly phones, think of them as something more like a giant PDA. The same way you didn't have to shut down your old Palm Pilot throughout the day- imagine waiting for it to boot up each time you wanted to quickly check your calendar! The idea was to quickly turn on, do something and turn off. That's what a tablet is supposed to be.
Seems most here are bringing personal preference/philosophy into this. The question is what was best for the tablet. So, I looked it up...
The biggest factor is the battery, of course. gTabs have Li-ion polymer batteries. Here's a decent synopsis:
Li-ion and Li-ion polymer: Used on a lot of newer devices, has no "memory" effect, should be recharged as often as possible, actually likes to be charged and draining it regularly can cause the usage time to be shortened, can NEVER be overcharged so whenever you're near a charger put it on there. Besides those benefits a li-ion battery is lighter and smaller but the chemical can hold more charge than Ni-cad and Ni-mh.
So the one reply to your question said to error on the side of draining the li-ion batteries. This is incorrect information. You want to charge the battery before it gets below a 20% charge. Also batteries will not go bad from accidentally doing the incorrect charging procedure here and there but normally follow the correct procedure.

Yes, I remember 5-6 years ago, there was a whole movement about li-on and polymer batteries (which are VERY different, btw) being charged as often as possible.
My theory is that this was started by battery manufacturers, as every person I know who followed this philosophy needed to replace their batteries during the useful life of the product (be it cell phone, laptop, etc).
The general theory (and the one I have had success with), is to NOT plug it in unless you are ready to charge it 100%. How often you charge doesn't matter, however do not disconnect a battery if it is in the middle of being charged.
But aside from all this, I thought the question was how is the G-Tablet supposed to be used.
The answer is, like a tablet. Not like a computer. If the G-tablet can't be used the way a tablet is supposed to be used, its not a very good tablet then, is it?

Powering off? Should really have no effect on battery life in the long run. The cons are that you have to wait for it to boot back up again which takes substantial power and time.

Meanwhile, buchaneer.nl, part of the philosophy of the tablet concept is that it is supposed to be always on. Otherwise, if you intend to use it like a computer a netbook is an infinitely more functional tool for the same money. No hacking about to enable Skype, Netflix, Hulu, you get full office and a keyboard, etc. They are just different paradigms and designed for different uses.
A tablet is supposed to be casual use. Turn it on, turn off. Hold it. charge it when it beeps. Repeat.

Why is that offensive? I'm sure when I get past the BIG 30 I will find it hard to operate the new neural interface devices and the star trek transporter-like technology.
When I was in college, one of my engineering professors was 90 years old and could write programs in like 50 languages. So, I'm well aware that not everyone from that generation is tech illiterate. That said, a very large number are. It's a fact.

The question was, is it better to turn it off, or does it do harm to leave it on all the time. The answer is it doesn't matter, so long as you perform proper charging of the battery.
As has been said, this is not like a computer, which has hard disks drives which wear out from spinning (and thus, reboots take a toll on the device). So rebooting does no harm, other than impatience for waiting.
And I guess as part of the over 30 crowd, I remember when booting a computer took FOREVER. So to me, booting the gTablet is nothing. I leave it on if I know I'll be using it in the near future, but otherwise, I turn it off.
[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.

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.
As well as the nook I also have an asus transformer and a bkackberry Playbook.
The Nook and the transformer seem to have similar standby time but I realised today that the Playbook knocks spots of of both of them. The playbook has been sat on the table in the living room for a good few days and it's been just in normal stanby with wifi still on (not sure if it shuts off when it sleeps). I picked it up expecting it to be flat only to find that it still had 30% power left!!! The nook just couldn’t do that length of time I'm sure, if I leave it it may last 2 days I guess.
What sort of standby time are you all getting? Do you set wifi to disconnect when it sleeps?
Woah, that's definitely NOT the standby time I get. I've set my Nook Tablet aside for a full day without use and the most I've seen it drop is 1-2% of its battery life. In fact, I haven't even charged it the past 1+ week and it's still around 70% (and that's with minor reading inbetween at low screen brightness and WIFI off).
I'm pretty sure I could set my Nook Tablet without touching it for a week straight and it'd still have a majority of its battery life like a champ.
The only thing I can possibly think of that's helping is my use of Juice Defender I have running in the background, but its main battery saving function usually involve s around minimizing WIFI activation as far as I can tell, and that is somewhat moot if I have it off.
yea I wish my NT could sit around not charging that long but really no complaints here. I get a good day out of it

Well from what little I know about the two tablets they both have the same base chipset and very similar screens so Nook 'should' be able to do the same as the Playbook so I'm definitely going to look into it further
well we need to find out what the secret is lol
I get days out of my NT when I don't use it, though even when I do use it I barely seem to put a dent in the battery percentage.
I'm so used to my old laptop and many phones over the years that I had to try my best to squeeze a day out of, that this thing just blows my mind sometimes.
My mom has a Transformer and she seems to have similar battery life to me, going on days without charging.

With my transformer it'sbecause eit dien'st sleep when connected to the dock, it's a known issue and if I got off my backside and contacted Asus they'd RMA the dock and fix it. If I disconnect the dock form the screen I get days out fo the screen even if I do use it a bit
Nook just doesn't seem to compare. Not yet anyway...
I'm on my fourth day, without a recharge. I haven't plugged it into anything since I started using ADBWireless. I can't estimate the screen-on time accurately, but I've read over 200 pages of memoranda and have been messing with my widgets and layout a fair amount. It's at 36% right now. I don't plan to plug it in until it dies (for science!).
anyone have any thoughts on this? I'm getting poor battery life as well. I'm running current widget and when I come out of idle there is quite a bit of current being drawn (200ma).
I'm rooted running go launcher.
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

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...

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 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.
I have never owned a phone with a non replaceable battery before. I have my One on it's first charge now. I am curious how many charges do you think this battery can handle before we start to see some decline in performance? I read with iPhones people can expect 300-500 before the batteries lose 20% or something like that of total capacity. I know our phone is different so that means very little here just using it as an example. I want to charge my phone as needed but would hate for the battery to be trash in 6 months or less. This is my primary fear with this phone, so guys tell me do I have nothing to worry about charge away... Or should I try to really be conscious of when I am charging?
Thanks in advance guys!

That's 300 to 500 full discharge-charge cycles. If you only run the battery down halfway at the end of the day and charge until full, it's roughly half the wear of a full cycle. There's some benefit to longevity with having shallower discharge cycles, but not enough that you should worry. There's a lot of variability depending on the battery type, the charge controller, and the chosen charging profiles.
Most modern LiPo batteries can easily get 300-500 charge/discharge cycles before hitting 80% capacity. Those are full cycles. If you only partially charge or discharge the battery, you're not using up a full cycle.

2 years is just such a long time. I guess the fact that this is my big concern right now means I have no REAL concerns with the phone so far. Besides it getting pretty hot! I think I'll notice the heat a lot less once my case arrives. What do you guys honestly think the shelf life of this battery will be even if it is just an educated guess?
Personally I feel that with technology these days, your phone becomes obsolete before you have to worry about your phone battery actually dying. Best thing to do in my opinion is charge whenever you can. From my knowledge, and correct me if I am wrong, its best to keep the phone above 50% charge
Yeah, I keep a charger in the car, at work, 2 at home, and Mophie Juicepack powerstation backup. (the last one is awesome for camping amd airline travel)

I have all of those things too, different kind of juicepack but same idea. My fear is just charging the phone nearly 2 times a day for 2 years! Even 1 and a half times. I use my phone a lot. I won't be one of those people with 50% left at the end of the day. I know I am overreacting and I should just enjoy my new amazing phone. I just can't help but be worried that the battery is gonna crap out like on my inspire after a little over a year. I also won't be getting a new phone before the 2 years are up I'm always in for the long haul.

I have the exact same concern. I'm not too sure how simple it would be to just send it in to an HTC service centre to replace after a year.
HTC in South Africa has a poor presence.
