Extended batteries?

Are there any yet for the Galaxy Tab?

having batt life issues? its been a champ so far for me.

Isn't 4Ah enough ??
PS: yes, the iPad has twice the battery capacity, but its display is twice the size, it's twice the weight, and there's twice as much room inside the device to throw-in a few more mAh

Getting the tab apart for battery access is quite a trick. I dont belive its something the average user is goong to be interested in. Peraonaly, i have been on this for as much of the 72 hrs ive had it and cant complain about the batt. One bit. Even on the rare occasion it gets lower then i feel comfortable with a few minutes on a/c brings it up nicely. I would like a longer cord though.
Galaxy Tabs.....Worth every penny!!

I'm looking for one at the moment so I can get an additional 5 hours out of the tab, more if possible as I'm going on a very long haul flight at christmas. So far I've not had much luck. If anyone can recommend one I would be grateful.

My MiniGorilla external battery pack seems to be able to charge my Tab, though since it is rated at only 1A output it would likely charge quite slowly. It might be enough to keep it going for an extended plane journey though.

Dave

Thanks for the tip, ill get right on that and take a look at it!

I've found one which seems to be rated at 5v providing 2 amps via usb from zagg.com the product is the zaggsparq 2.0. I'm going to order one to test out since they ship to the uk and will let you know if its any good.

Watch the reviews on the zaggsparq... Seems like it may be apretty shoddy product. Looked awesome to me too, reviews gave me pause.

Well i've been using the Zagg today and it does work with the galaxy tab but I had to use the general usb port as the optimized port for some reason is treated like a pc usb port and you get the no charge symbol over the battery.
So far I'm impressed had it plugged in charged my tab from 70% to 100% and still the zagg is showing 3 led lights out of 4.
Takes a bit of fiddling I have to plug it in turn the display off on the tab. Leave it for a minute and when I turn the display back on it shows the charging symbol and actually starts charging while I'm using it.
I can't recommend it yet as I've only used it for a couple of hours so I'm waiting for my trip at christmas (27 hours of flying) before I make any judgements either way.

[Q] How long does your tab 8.9 charge?

How long does it take your Tab to charge from about 0-20% to 100%?
It takes mine forever - about 16 hours, although I'm on stock Honeycomb rom

I'm not completely sure, but 16 hours seems to be too much to me. I usually charge over night, so i guess it might be something around 8 hours.

I think so too!
I just wonder what is causing this... (1) some faulty chip in the tab itself, (2) faulty battery, (3) faulty Samsung cord or (4) faulty charger. No way to find out for sure, unless I return it to the shop and wait about 30 days (at best) while they figure that out and give their verdict
I hope someone has\had this problem and knows what exactly was causing it.

the last 5% take forever. That's usual behaviour for charging. Check out how long it takes to charge to 90% or maybe 95%. Should not take longer than 6 hours. If it does then maybe try a different charger or reset your tab to make sure it's no software bug.
Hard to tell the real source of error, sorry...

Are you ABSOLUTELY certain to be using the original, for your tab, charger, with a 2 amp output.
With such charger, it should be about 4 - 4.5 hours.
But if you are using a generic, or something made for an avg phone, with .5A output... Well 16h seems normal

Mine is about 6h

I am using Samsung banded charger that came with the Tab.
Sometimes it does charge fast, but most of the time it either charges very slow, as though it were charging from USB, or doesn't recognize the charger, or even says it's established MTP-connection...

from 8 to 10 hours on hc 3.2
but now on ICS take less

using the charger that came with the tab, you should get charging times around the 4/5 hours. HC 3.1 and 3.2.

Does the cable work properly when you use it for USB operations (file transfer, etc.)?
If so, then maybe the charger is broken/faulty. Samsung (in its infinite wisdom ) put a resistor network in their chargers so that the tab/phone can recognize a charger vs a usb connection ... or maybe just to make money from over-engineered accessories. who knows? However, if that resistor network has failed (or the cable is broken, hence the question above about USB operations) then the charger will present as a USB port rather than as a Samsung power source.
Oh! Another data point to consider: does gently wiggling/straightening the cable when it's connected cause the behavior to change?

There isn't much difference with ICS 4.0.4 US rom in my opinion. And it is still picky what chargers it accepts when it's turned on (DX.COM charger works for me). I usually turn the TAB off and use a stronger charger, but it still takes a LONG time to charge in my opinion. I do an overnight charge as much as I can.

Did an overnight charge with the Tab turned off, and it charged to 100%, finally. But when it's on (even in airplane mode) it only charged to 60% last night (took 12 hours!).
Weird)

i always charging my tab from 0 or 2-5% to 100% either when powered on or off and it always takes 5 to 5 1/2 hours. no more and no less with default charger set.
first i thought it was taking too long but when i saw this thread i'm glad its only 5 hours

Common belief (knowledge) is that this is not the best for a lithium ion battery... It increases the wear, gets it to lose capacity sooner... If possible, charge your battery often, like as soon as you can below 75%. Only occasionally drop battery to 0%. IIRC, there's a good website called "battery university" talking about that

Thanks, used your post to fix mine. I ended up replacing the cable and not the charger. I'm using an original charger with a new cable now.

I am seeing same problem with my brother's 7300 tab as well. Its taking around 10 or more hrs to charge.
Anybody got tablet replaced in warranty for the same reason? Even with Nexus 7 original 2 A charger its taking too much time. With samsung original charger also it was taking similar time so i am sure problem is with the tab only.

4-5 hours on mine.
Sent from my GT-P7310 using xda app-developers app

Many Galaxy tab 8.9 owners have reported experiencing long charge times to the tune of about 16 hours, me included.
Solution:
Plug in the charger to the tab very very slowly. The charge icon in the system tray has a lightning symbol on it aka normal charge.
Connecting it at normal speed results to the charging icon in the system tray having a cross on it. It then charges very very slowly.
Why should we need gymnastics to normally charge our tablets? Ask Samsung.

[Q] Does the One discharge faster than charge?

After seeing how slow the One charges in Anandtech's review especially because fast charge is disabled, I have to ask this question, does it charge (AC not USB) if you are for example, browsing the web on​ it?

Definitely yes. I've only found one moment where it's discharged while charging.
That was when I was playing music as well as playing Shadowgun Deadzone at the same time. It was still charging more though because when the game was at a menu (i.e. not as much game activity) it would charge as normal.

Well that's great news as web browsing is as heavy as I ever go on my device, never play games.

I've noticed that while charging in the car and using GPS it discharges slightly faster than it charges so possibly on a very long trip you may eventually run out of power especially if you don't start off with a full battery.
With my iPhone 5 the phone would always charge when using it as a GPS and would get to 100% very quickly.

The battery on mine does seem to go down pretty quickly, if you game youre looking at a few charges a day. At least that's how it's been for me.
Maybe my units a bit dodgy

Strange, on my evo shift (old phone if you've never heard of it), the battery will continue to charge even when running intensive activities such as playing 3D games and such
It also depends on the adapter...Battery Monitor Widget by 3c lets you see the input mAh

That's really bad. I haven't had that for years (since my HD2). In the car try a 2amp car charger. May solve that.

Are you using a 2amp or 1amp charger?

How's your battery life?

My battery life is decent, but the charging time is the slowest I've ever seen on any device I've ever owned. I'm not even kidding. Surely it's just a defect on mine right?

Negative. My charge time was ridiculously slow. To the point that while I was charging in my car, if I was doing things along side it, my battery would actually go down. Plugged into wall, it is slow but charges though. Maybe its just US or a small number?

Waiting to get mine still. Did anyone else notice that on Sprint's website it said the One has a 19 hour battery life?

It seemed a little better this afternoon, but I've basically had the device plugged in since this morning(10am)(got it at 55%, and albeit the majority of the time, it was plugged into the vehicle[which hasn't been very good anyways[[my GS3 also loses battery while on charge if doing anything concerning navigation or streaming]]]) and it literally hit 100% about 20 minutes ago. granted I've been using it like a pack mule. and I'm sure you have too.

i heard they packed a li-polymer battery which makes the battery hold its charge longer for the life of the battery when compared to a li-ion battery.. and i dont think htc enabled fast charge like most devices...maybe someone will mod that for us...we need fast charge!!!!!!! still waiting on my ONE

Actually I haven't used it at all. Got it at 2 PM, was at 60%. Dropped my mom off at the airport immediately after, came home and it was 50% at 3:20 PM (which is okay because LTE was on by default and it's super patchy here so I turned it off). Plugged it in and showered, 15 minute shower and I come out and it's 50% still (plugged directly into the wall). Went to work at 5, 55% when I got there. Plugged it in to the computer we have at the front desk and over the course of my 5 hour shift it eventually hit 95% before I had to leave at 10 PM. Un-****ing-acceptable.

yeah, I'd say mine is a little better than that. I left the screen off and didn't use it for like 2 hours and it went from 73% to 91.

I bought a 2.1 amp charger and it hoes from 0 to 100 in 4 hours

I don't have my One yet so I can't confirm this personally, but I've read in a few different places that the charging rate is a little slow compared to other phones. My guess is that HTC is trying to maximize the lifespan of the battery since it's non-removable. Quicker charging would generate more heat and might cause it to wear it out faster.

Yes this is the case. Check anandtechs review.
Brian speculates just as you do that it is for longevity.

First day I got 15 hours. That was the usual installing apps and watching YouTube videos and showing my phone off to everyone at work. Will probably be awesome once I don't have such heavy usage.

If I'm not mistaken, the phone has a smart battery or a circuit inside the battery that prevents it from drawing too much current. It is pretty much a standard among smartphones these days. Therefore, even though you use the 2 amp charger, you may not charge faster at all.

My Galaxy S3 definitely charges faster with a 2AMP charger than 500 mA charger.
Do not charge from a computers USB port, they are going to be slow as **** without fast charge.
Just use a 1+ amp charger. Pretty simple people.

Don't put excessive work load on the device while charging in the car either

I've found thats too much for most phones. It all depends on the charger(most car adapters are crappy), I'd assume. I've had the same with Evo, Optimus, GS2, and GS3. If anything is running alongside gps/navi, it destroys the battery

[Q] Charge Time

Okay. I apologize if this has been covered *blushface*.
I have recently rooted my note III. I love the functionality but hate the amount of time it now takes to charge. It is taking more than eight hours to get a full charge. I figured out how to manage the charge to avoid multiple charge times within a day. So plainly stated. How do I get a shorter charge time? I would like to wake up with a full charge!

2 to 3 hrs for mine to go from 10% to 100%.
Are you sure your using the supplied power supply? It has 2amp output.
Read the output stats to your charger please!

Then unfortunately u have a substantial problem my friend.
The supplied 2a charger charges at a rate of 2000mah (milliamps per hour).
The N3 battery's capacity is 3200mah.
If u drain 3000mah leaving only 200, it should only take 1 1/2 hours to reload 3000mah
(these are not "exact" numbers, but pretty close).
If it's taking you 8 hours to put 3000 mah into ur N3 batt, you have a problem with something -
8 hrs charge time should supply 16,000 mah (over 5 times the amount needed)

What do your battery stats say?
Does your device stay charged like it used to? Is it possible you set something up to do work while only plugged in and charging?
Tried another 2 amp charger?
Tried another wire?
What programs did you grant root to?
Have you ran a malware scan?
There are a lot of variables here to examine.

Thank you all for the advice. I looked into the battery stats and everything seemed normal.
The battery was performing almost as efficient as with the stock ROM. I wouldn't expect exact performance from a custom ROM OOBE from prior experience. I was not perfectly happy with the DK ROM that i flashed and suspected that the ROM may be the issue. I decided to try the Alliance ROM.
POST Alliance ROM: Battery is charging like normal again. Performance is pretty standard. Problem resolved.
Thanks to everyone for the support.
P.S. Genjo Enterprises Apps are pretty stellar. i live in a rural area with limited data coverage and the internet booster app makes a huge difference!

My note 3 is rooted running the dynamicKat rom and it never takes me more than 2hours at max to fully charge my battery.

Your reply, while making me a little jealous, has neither added anything of substance or value to the topic of resolving my issue. Please troll on another thread topic.
