6 hours to recharge?

I recharged my Galaxy Tab 10.1 yesterday from a 15% remaining charge.
I powered it off and used the wall charger. It took almost 6 hours to charge to 100%!
Is this normal or is there something wrong with the battery?
Thanks!

Mine was slow at first too. But now seems to have gotten quicker.

What is the rating on the charger that comes with the unit?

The rating is 5V - 2A

Yep, noticed it took about 3 hrs to go 40% charging. Not sure why there is such a drastic difference from the Xoom which could charge from 10% to full in little over an hour with similar drain to GT.

Can you please quantify what quicker means?

We have a rather large battery in the device, while I agree 6 hours is abit much, it should be quicker at 2 amps.
On the other hand, I sit in on the charger at night before I go to bed. I am definately a heavy user as well, and the battery lasts me all day with atleast 30 to 40% left over by bed time (this includes a 1.5 hour commute each direction using Waze, the GPS, and wifi tethered to my phone, 2 gmail accounts polling every 15 min, web surfing throughout the day, and playing games during my morning and afternoon constitutions .. I know.. too much info)..
So I can live with a longer charge time, at least for now..

I charged my GT Tab completely before using it the first time. Then I drained it down to about 9%. I timed my first full charge from 9% to 100%, it took exactly 6 hours and 4 min. My Xoom charged in half the time. I am hoping it gets better like I have heard from different people.

i believe the xoom's charger is 16watts or more. i can't really remember, but it's got the highest rated charger b/t the xoom, tf, and gt10.1.

I think that's just wishful thinking on their part. How does a battery suddenly learn to charge itself faster. You make it sound like the battery is a muscle you can work out. The thing takes forever to charge but it also has excellent battery life. So as long as you don't find yourself in a hurry to travel without time to charge the battery should last you almost all day.

I charged the device fully before use. Used it down to 10%, plugged it in and charged to full powered off. This took around 6 hours. The second time I charged it from around 14-15% It took about 4 hours. I have charged it twice more since from almost zero, and it's taking about two hours.

Remember the math:
7000 mAh battery
2000 mAh charger
That means from drain to full if the screen is off, about 3-4 hours. If you have the screen or device on and it's doing anything, it's using some of that incoming charge, so will increase to 4, 5, 6 or more hours to fully charge.
Gets even worse if using an aftermarket charger, say a 800 mah or 1000 mah charger like the iPhone or Kindle charger...can then take 10-14 hours to fully charge, hehe.
It's funny how people say it charges quicker after a while, when that's not logical, you just don't notice it as much going from 65% to 100% as you noticed when it went from 15% to 100% the first time, hehe

The xoom charges super fast, like from almost zero to full in around 2 hours. That's about all i miss right now

Smaller battery=shorter charge, a 2 gallon gas tank is quick to charge too, hehe.... kidding.
But seriously, Samsung is bad with their charging. My Samsung Infuse and my Galaxy tab both take forever to charge.

Did I read it correctly that if recharged from almost 0 (e.g. <5%?), it takes only 2 hours to go to 100%? This seems counter intuitive.

i think what happens is that as the battery calibration gets more accurate it finds where to quick charge and where to trickle in the appropriate levels.

Nexus 10 Charging

Is it just me, or does this bad boy take all day to charge? The transformer only outputs like 1.2amps. I've only gone from 45% to 77% in like 4 or 5 hours. It's sooo slow

Mine takes a really long time too, though I haven't measured it yet. I just plug it in at night when I go to sleep and it's done in the morning. The battery lasts me all day.
Is there a reason you need to charge it while you're awake? This thing lasts 5-8 hours easily; surely you aren't on it that much!

From experiment, it looks like taking one hour to charge 10%. So total time for full charge is about 10 hours. I used the nexus 7 charger and it took about 16 hours!

No problems charging here, I just charge overnight

Mine also charges very slowly. Discharges when on charge if you're using it (depending on what you're doing of course).

My phone took around 2hrs to complete charge. If your phone took about the same time then it could just be a software glitch. Try factory reset or reflash firmware.
If it took obvious longer time let say 3hrs or more then it could be a hardware problem.

I reflashed the official rom poland one 4.4.2 but still has the same issue

Charging li-on battery gets slower towards the end of the charging cycle. That's normal. The only thing you should be worried about is how long battery lasts in use. If you have bad battery it charges up faster, not slower then also runs out of juice fast.
Charge with original charger and cable to make sure problem is not there.
I always leave my note charging over night so I don't know how long it should take to reach 100%

i just made my phone to run out of juice and i charged it up to 100%, it takes 2h and 15 minutes ( Phone was off while charging )
i think it's normal, isn't ?

Please Help moto x play huge battery issue

I used samsung fast charger for 4 months and battery life was all good , then i lost the charger so i had to charge the phone with a "not so fast charger" that took ages to charge my phone.
Never charged to 80% , and battery drain was serious.
That's when i got worried that the charger ive been using might have destroyed my battery.
So bought the "turbopower 15" charger for my MXP and at first it heated up my battery more then 60* (serious overheating issue)
After 2 or 3 charges i figured it only heats up after the percentage is 50% or higher or when i use it while charging.
And now it drain my battery like crazy!,
I just restarted my device into recovery right now and it was 45% but by the time i booted up to recovery it said 25%. How CRAZY DRAINAGE IS THAT??, Please devs help me.
Its like i dont need a stopwatch my battery drain a percent per second.
Im using purenexus 7.1.2 by @GtrCraft witb stock kernal

Same here. Battery quickly drains to 96% after unplugging from the charger. Takes half an hour max without using at all. After that normal drain.

May be new update is buggy ?

Since the last release I decided to stick with Nova Prime and no Google Companion. Before I was on stock launcher and turned off shelf. Charged to 100% and over night battery drained to 99%.Right now I am at 77% with 2 hrs of screen time and been unplugged for 16 hrs.
I would think that shelf or Google Discover is a battery drain for sure.

I don't think so. It's happening on custom ROMs as well. For me it started from one day on another. Weird thing but I think that's the ACTUAL capacity of the battery. You'll actually never have 100% battery when unplugging from the charger after some longer charging. It just shows you that.

I noticed as well. I think its because of my extended use of fast charging as isn't good for the battery. But I thought that the heat was going to the charger and you should use the charger that comes in the box.
However, from extended use of my 6T and my previous phone the OnePlus 3. Dash charging affects the battery even though heat doesn't go to the phone, it affects the battery health. And you shouldn't use it especially if you want to keep the phone for 2+ years. I've been using my 6T since December and my battery health is around 70%?! I only been using dash charge as well for both of my 6T and OP3. The reason I upgraded was because of the degraded battery in my OP3. From this, I'm gonna send my 6T back to OnePlus for a battery replacement, so that I get a brand new battery and from now on I'm never gonna use dash charge and instead gonna use quick charge 2.0 chargers as I don't have a apple 5V charger. But this should still be better for long term, even if it is a form of fast charging. All Samsung phones since the S7 have been having this quick charge standard. Using fast chargers is convenient, but it is not good for long term and it is just another scummy way for companies to reduce the longevity of your device and make you buy a new one. Tbh Dash Charging or Warp Charging or any fast charging should only be used when you're in a rush and you're phone's battery is low

Thanks buddy noticed this issue too .. while charging on regular charger it's fine shows almost 3700 as health but on dash charger it shows much lower

So i figured something interesting ...
The ideal capacity of oneplus 6t is 3700
But rated or we can say usable capacity is of 3610mah ..
So according to that accubattery is almost right ...

Hey!
I got a new device one week ago. Felt the same. As soon as I unplug, it starts to tick. Battery backup is up for 24 hours only. But I have seen many say that it lasts longer. Suggestions? ? I did one update after getting the device. That's it. Even before it was the same situation.

In the beginning I had a similar issue. Drain up to approx. 85% went fairly quick,but afterwards the drain will improve drastically. Takes some time I think

It did for me at least. Otherwise it's an app issue.
I only have the "issue" that battery goes from 100 to 96% fairly quick but I don't really care. Drain afterwards is normal and getting over 10hrs SOT easily anyway.

Mine does this but I noticed that if I reboot my phone every morning before taking it off the charger, this issue goes away. So I'm guessing there is some sort of trickle charging happening once the batter reaches capacity. I also notice if I take the phone off the charger as soon as it hits 100%, battery does not drain to 96% quickly as well. Must be something with the way one plus software works with charging
