Hi i dont know why my battery isnt completely charging! or the battery charger info is broken! anyone else not charging to 100%?
It probably hits 100% then starts draining slightly to keep it from over charging. Mine gets to 99% then I unplug and replug it and it hits 100. But that has happened with a lot of devices for me.
Happens on my evo as well. You can get around it by flashing a kernel that does trickle charging which I'm sure we'll get for the tf sooner or later.

I would NOT use an sbc kernal on this battery, they are known to shorten battery life. Cell phone batteries are a dime a dozen, this thing is both non-user replacable and most likely not cheap.
Pretty sure its a lithium ion battery inside and you shouldnt overcharge those. You're best off keeping it between 30-90% and doing a drain and full charge once a month to prolong its life. The charger should stop charging when the battery is full on it's own anyways if you do leave it plugged in. I think it's a European law to have that as a safety feature, probably an American law for this too. So if the charger is staying hot a few minutes after your device has hit 100% charge, you've got a problem. Mine does get to 100% but yes it takes a while to top up, that's just the way these batteries operate.
Do you only use the HTC charger that came with your phone? MicroUSB is MicroUSB and it will charge from any charger BUT I have heard that different milliamp chargers can cause undesired effects in the battery (of any phone) such as decreased lifespan or less battery life in the short term. Any truth to this? Only reason I ask is because A) I'm curious and B) I got my Sensation yesterday, charged it with the stock charger at work but left it by mistake. When I got home, I charged it with another charger I had lying around. After 8 hrs off the charger, I had dropped from 100% to 99% (awesome). I then made a phone call this morning for 6m and used the display for 15m and it dropped to 94%. I then left it in my pocket for another hour and it dropped to 90%. I don't get it! :-(
Two separate issues here:

The official HTC charger is 5V 1A. Some other chargers, such as car lighter chargers and USB ports only give out 0.5A, so charging takes much, much longer. In fact, if you use a 5V 0.5A charger whilst continuously using the phone for something battery-intensive like sat-nav, the charge will still drop, but not as fast as if it were not charging at all. You'll get a warning on the phone something along the lines of "the charger is not sufficient to charge the phone and use it at the same time" (can't remember the exact wording). make sure you use 5V 1A.

This much I know. But they aren't all 1a. My old Defy charger was like .8 and this is 1a. I'm not referring to charge times. I pointed out your GPS point to an OP in another thread. I'm referring to if using a different MA charger effects the quality of the battery or how long it can run on a charge.

Conclusions?
How many amps can one charge at?
I see car charger product that claim to output at 1a, 2.1a, even 5a.
Then I see that it may not matter what the output of the device is: that unless the cable you use to charge shorts the center two pins together, you will only get .5a.
Bump.......
I've always understood that a "trickle charge" or a slower charge is better. I only charge via usb for this reason. It takes much longer to charge, but supposedly it charges the battery in a better way and it will discharge slower.
Any truth to the battery conditioning tips I've seen about letting the battery charge and drain 3 times completely when new? I have read that these lithium batteries dont require that but I keep seeing conflicting info.

In addition to that, I'm curious on how you all charged your phone the first time. I want to make sure that I do it right when I get my Sensation.

I used the wall charger initially but then switched to USB which actually seemed to work faster. I used my N1 charger earlier.
Anyone going to advise on battery drain? Losing 4-5%/hr idle. No, it isn't an app.

Because I had no apps installed that would do that, there is nothing in battery use, etc. 2%/hour is high for the sensation.

There are apps and processes that are part of the system that can drain power like that. Having a bad signal and constantly dropping connections can run down your battery. Did you pick up watchdog for free on amazon yesterday? That can tell you more about what is using the cpu.

Well that's okay then. I was stupid enough to think you might have used something such as System Panel or Current Widget from the Market to actually verify the battery drain and the tasks/apps that were responsible.

High? My HTC Desire drained 1.75% per hour with CM7, so 2% for a dual-core phone running HTC Sense is pretty impressive, IMHO.

If you read up on the reviews, you will see that the Sensation has achieved <1%/hr drain with items syncing.
Im really anal and I dont open my phones accessories if I dont have to lol. I have been using a spare MT4G charger and its working fine. It is rated at 1 Amp like the factory Sensation charger is though.
For those wondering, as slow as these batteries discharge you will probably not see any gains in performance when you trickle charge a battery (for example over USB) over using the stock charger. It is recommended you fully charge the battery and fully discharge it the first time you use it. The battery life will get better after a couple cycles, yes they need to be "broken in". Like all rechargeable batteries they will degrade over time, it is inevitable. Since OEM batteries are so cheap these days I personally dont go too far out of my way to "properly" charge and discharge my battery. It will die when it dies, at that time I will just buy a new battery.
I just got my Asus Transformer, I charged it full out of the box for 8 hours as initial charge. Should i drain it to 0 % and charge it for second time? or Just wait until 10 %?
Doesn't matter. I usually charge it when it gets to 10%.
For the first times I waited till 10% or something to fully recharge.
But after a lot of reading about the matter, I have found lots of opinions, so I think it doesn't make a big difference.
Regards.
Alright. Thanks man. Will just charge when 10%
From asus manual:
"Remember to fully charge the battery (8 hours or more) before first use and whenever it is depleted to prolong battery life. The battery reaches its maximum capacity after a few full charging and discharging cycles."
After awhile, Lithium-Ion Batteries don't really care how you charge them, or what their capacity is. Charging a battery at say 50% vs 10% won't really add that much more juice. I wouldn't really concern yourself OP..
Guys, the first 8hour charging means that I must charge separatly 8hours tablet and next 8hours dock? Because I put dock and tablet together and charge it 8hours. Was it wrong? Then I was using it connected tablet+dock together until it was showned warning that battery dropped under 5% and orange LED on the side of dock was blicking. Then I charged it again together and after 5hour of charging, LED is green and tablet shows 100%. Is it OK? Did I do something wrong?
Thanks
One question to you guys: During the first 8 hour charge, were you able to turn on the tablet? Because mine is sitting since 2 hours now and it won't turn on.
I have managed to turn it on.It required to keep the On button for about 10 seconds.

You're fine. The goal is to get the batteries fully charged rather than, say, up to 50% and then stop.
Last I read, LiPo batteries do not need deep cycling to maximize battery life or restore lost capacity due to battery "memory." Some recommend an initial full charge followed by full depletion, but go on to note that is largely to calibrate battery usage stats. I keep most of my LiPo devices plugged in when I'm not using them, because those batteries require "smart" chargers that stop charging when the batteries are full.
If someone has good info to the contrary, I'd love to hear it. But, with well-made devices and chargers, there is no need to follow any sort of careful battery charging regimen. Use it when you need it, and charge it when it needs a charge.

Mine was partially charged and turned on out of the box. Perhaps you have a power button with a loose connection? As long as it's working now, I would not worry about it.
finally today I recive my TR from US,& question is
are all of you guys ,charged 8 hours your TF
coz my is after 3 hours of charging TF is full 100%
& stay like that almost 2 hours more...
should I wait more 2 hours(for calibration reason)
or I can use it now
In the manual, it says charge for 8 hours before first use. I doubt that using before 8 hours is up will damage anything, but why risk it? I'd leave it on the charger.

Thanks for reply. My TF last 15hours of work after second charging. I think everything is OK with battery.

Right in the little pamphlet (that counts as a manual ) under the TF in the box. I'm sure, because it's one of the few times I've read a manual in the last decade.
I´m charging my new TF for the first time and it´s reached 100% after 3 hours. Is it ok to start using it now or must i wait 5 more hours for the 8 that´s stated in the asus-booklet?

^^ Be patient and let it charge.
Just curious how you handle this, because everybody says something different:
First use: completely charge the battery and then complete discharge, or first complete discharge and the full charge?
I also remember someone telling me that you shouldn't let your battery run completely empty, is that true?

just charge it when it needs it, dont worry about what % its at, and dont worry about running them right down... the phone will power down before it gets to a dangerous level for the battery.
dont leave it plugged in all the time when its sat at 100, dont leave it down at 0 and just forget about it for weeks on end...
thats all you need to know

I don't buy the bit about wireless charging. I've used my Nexus 4 with an LG wireless charger daily for almost a year now and haven't noticed any side effects with battery drain or overheating. In fact, I'd argue that the Nexus 4 and my Nexus 7 get hotter when plugged in than they do on the wireless charger. I have absolutely no reservations about using the Nexus 5 on my LG wireless charger when it arrives this week.

Well the charge and discharge isn't necessary, IIRC that's only for older battery technologies like Ni-Cd batteries (Nickel-Cadmium). On the other side, you probably shouldn't let it discharge all the way since these are Li-Po and it could shorten their lifespan (apparently).
I just plug mine in whenever I'm near a charger.
I'm at work at my desk... its plugged into the charger.
I'm in my car... its plugged into the charger.
I'm at my girls house... its plugged into the charger.
I'm at home replying to xda / android central posts... its plugged into the charger.
This is what I've done with every phone I've had. I only had issues with one battery. I used to have sprint and I had the Samsung Galaxy S2 Epic 4g Touch. After about 8 months the battery got fat (they said it was called a swollen battery at the sprint store) and it kept turning off. They gave me a new battery at the sprint store and I continued with my routine above and never had any other issues with it or any other phones.

this is right on both accounts. you dont need to discharge it all the way, and doing so will reduce its life a little. i recently read about lithium poly batteries and the particular blog i was reading talked about running the battery down to 20% then charging it to 80%
i think when i first get the device i will use it down to 0%, charge it up to 100% uninterrupted and then hopefully keep it within that 20/80 range and probably doing a 0-100 refresh on the first of every month
If you guys want to read some in depth material on charging lithium batteries I would recommend reading this. Very informative.

It's fine. Phone manufacturers know that people charge their phones overnight. That's why there is a trickle charge mechanism built into all phones nowadays.
u have to calibrate the battery too
Over the last month I've had somewhat of a binge of buying phones from Amazon and returning them for one reason or another and I've noticed that the first 1-3 days of phone ownership are usually the toughest on the phone / battery.
I've owned over the last 2 months (in order):
- S4
- HTC One (x3 as 2 were faulty out the box)
- LG G2
- S4
- N5
I've decided on the N5 as being the best for a number of reasons, but my favourite is price.
I havn't worked out whether it's a combination of new phone = more usage or new phone = requires battery calibration. But the N5 is the only device out the major players that actually made it through day 2 (the day after it came out the box) without a charge midway, infact it's ONLY JUST gone on the charger after some 28 hours of moderate (3 1/2 hours screen on) usage.
My gut feeling is that once you're out the first week just use the damn thing, but the first few charges can make a difference to how quickly the battery feels calibrated. My N5 came with 50% charge out the box, I ran it down to 0% and topped up charge as much as I could the first day. Once I got home I once more let it 0% and then did a full 0-100% recharge. Then my 28 hour experiment started and now I'll just use it as normal, and not worry.
I keep brightness at 50% to enjoy this beauty and I do not give a single **** about the battery.
Charge battery between 20% - 80%

Unplug charger when battery full
Hello guys sorry if it is an innapropriate question but I want to know if it is okay to charge my s8+ over night.. does it damages the phone battery or not ? Thanks
I wouldnt. Doubt it would but would but i find it pointless. It charges pretty quick and wouldnt want to leave it charging for 5+hrs The battery is superb i would quick charge a few mins before bed. Ive gone to bed with 19% and had 17% when i woke the next morning.

It's not going to outright destroy the battery, but definitely better not to keep it on the charger. I cannot speak to your schedule and work environment. I charge mine mid day at work. If your usage is generally the same on a daily basis, just find a spot where you can squeeze in a charge or two during the day.
Always changed overnight for ever I can Remeber. Never faced any issues.

1st of all in modern battry charging technology overnight charging doesnt harm battery at all as lith ion batt never get overcharged..bcoz once its 100%(max threshold) charging stop and phone use batt powr
after that once it get around 100% ( lower threshold) it start charging again...
STILL I PERSONAL ADVICE TO CHARGE OVERNIGHT WITH FASTCHARGING MODE OFF(((OFFF)).

As far as I know, technically wireless chargers are worse for the battery than a wired. They produce more heat, which technically will have a larger impact on the battery. That being said, I doubt there is any appreciable difference.

Good point. Does ths fan cooler on the wireless one prevent as much heat?
The battery retains 95% battery life after a year of normal charging, I wouldn't worry about depreciation. Relax and enjoy the phone
No, you can charge your android overnight as they are smart enough
Boooom! Lol.....just kidding I hope
Stick with the samsung fast charger. I have a lot of other ones, and only the samsung stay cool (fan) and doesn't cycle like the cheap ones do.
Yes, as most have said, you can charge overnight. I have done this every single night for years, on all my flagship devices. Smartphone batteries have technology in them to stop charging when they hit 200% and only trickle charge them. It won't do any damage or won't cause long term battery life issues.
Just turn off fast charge if you're going to charge overnight.

I've also heard the opposite, as wireless chargers charge slower they put less pressure on the battery which helps it not degrade as fast. How much difference it would make either way I dont know, possibly hardly any.
I do know keeping it between 40-80 is widely regarded as being a lot better for li-ion battery degradation than going to 100% all the time or running it really low. Accubattery for example will say you used about 0.2 battery cycles going from 35% to 80%, but 0.92 battery cycles going from 55% to maximum. They are probably just using that 40-80 rule to work it out, but assuming it is correct, you can see how much effect it has, being nearly 5x more battery cycles despite both being around a 50% charge up.
So charging it overnight will get it to maximum, which isn't great in terms of battery cycles. I have seen a couple of battery apps that I think can manage charging so that it notifies you at 80% to unplug it, but I don't think they can actually stop the charge at 80% if you leave it plugged in (althought I might be wrong on that). Again how much real difference it will make I don't really know, and it probably depends how long you plan on keeping the phone, 1 year then it shouldn't be too much of an issue, 2 years or more and I would probably at least try to keep it between 40-80% when possible.
Ha,
Been charging all my phones overnight.
Been using wireless charging since the note 3 and always please it on the charger when im next to it and not using my phone.
Never had a battery problem
Thanks everyone for their answers ..*let the overnight charging begin*
I used Ampere to check how much current was going to my phone when it was fully charged and it read 0.0 so I believe the phone cuts off the charging function when fully charged. As even on 100% without the "fully charged" portion on, it will still show trickling voltage.
Hope this helps. I also advise turning fast charging off at night just to be safe.
