How long does it take for a full charge? [Culprit: Bad USB cable]

Well I need to know from you guys, it's not that I don't know, but need to reconfirm. I think mine is taking much lower now than it was. A full charge, say from 5% to 100%, with Stock charger?
Thanks in adv.

roughly 1 percent for 1 minute. should be charged in a couple of hours

Charging from 0 to 90% happens in no more that 2 hours I would say. from 90% to 100% the charging rate gets slowed a lot. So basically shouldn't take more than 2:30 hours from 0 to 100%.

Thanks guys. Now I remember it was 2 hours 45 mins for me too at first.
Today it took 4 hrs 30 mins. Reason? I'll say tomorrow, after confirming.
Jeez PowerAMP!

I rarely charge it to 100%, usually to 70 or 80%. much better for the battery in the long term

Any research or refrence for this longevity ? I heard its always better to charge 100% ?

Thanks man ! Really helpful article...

you are welcome. the general rule is to try to 1) avoid charging to 100%, really diminishing return the higher it goes; and 2) avoid deep discharge cycle. I usually use 40% of the capacity at work everyday, so charge to ~70% in the morning, use down to ~30% and then charge again. charging time in this range is rather linear, about 1 percent a minute

Yeah, it happened to mine too few days back. My Note2 went crazy, taking around 7-8 hrs to fully charge from 15%. So, i tried searching about the problem on google but to no avail. Did a factory reset with cache wipe and problem solved :good:. Now it takes about 2.5 hrs to fully charge from say 10% (using the samsung wall charger with phone switched on). I can only say that the slow charging was caused due to some software but don't know exactly which one? You may as well try the hard reset if anything else doesn't work out .
P.S : Btw i'm on stock fw with no root or mod! Only did some OTA updates couple of weeks ago.

Guys, we have a changeable battery and is already writed Inside to android that it won't charge to 100%, it just shows at 100% but really it is at 95%-98% that feature came with 2.2.1 update 2yrs ago.
And we can change the battery after 2yrs for 20-30$, unlike Nokia lumia users or HTC one x or iPhone users.

Yeah, thanks. But if you've Watchdog installed then you can see which app is going over threshold and keep running on background. And yes, this time, again, the culprit was PowerAMP! Uninstalled it and voila. The same app created problem for me when I had my S2, charging was pathetically slow, even I had to go to SC and they said battery is gone. But I didn't believe and asked a techy friend and he said it might be some app, and damn right he was.
Anyway, if anyone having the same issue like mine, that is, charging duration has increased with Stock charger, then install Watchdog (the lite version will do) and see who is the culprit.
I have no idea how a top app like PowerAMP could cause this! Jeez!

The same problem happen to me few days ago..during that that i was charging using extension cable where 3 pin plug is sharing with my note 2, laptop n tablet charging @ the same time..its take nearly 4 hour for fully charge the note 2 while im using n charging my laptop n tablet..but, from that i understand that when the connection all charging at the same time on the same 3 pin plug, the load are higher which decrease the current value (current drop)..that the reason why my note 2 charging slow..check if OP case is same like me??

Hmm! Thanks.
Well I wasn't using the same plug point but the charger was connected to my Belkin Gold surge protector, where my whole PC and monitor is connected. Could that be a problem?

Is this long-charging-time problem a single occurrence or you are consistently having this problem?

1.5 year already? Check your battery, please. If it's pregnant/bloated/bulging, replace it immediately.

If the battery didn't affect battery drain or such. Maybe you can still hold on for a bit longer. And also if the "fat" disturb the back case you should change it asap

Battery not discharging properly

Since installing 4.4.2 my battery isn't discharging, at all! It's been stuck on 100% for the past four days. I haven't really used it much since but the battery should be way down by now.

Isn't that a good thing?

Are you still having the same issue?
Because I think I'm maybe having the same problem.
My tablet keep shutting off at 40% as if is 0%. It all started since this past weekend.
My tablet is unrooted ,try to search the web for a solution but haven't found one yet.
I'm trying avoiding to do a factory rest because I read the issue still persist.
Everytime I recharge my tablet it stay a long time on 100% and the moment it reach 40% it shut down a,msg appear saying battery low and shut off.
Also take note I've read about those app calibrator but keep reading that a myth.
Let me know if your still having the same problem?

No, I actually fixed the issue. Believe it or not I used a calibrating app and Root Cleaner and did a full clean and it appears to be working as normal now. I'll add later which battery app I used, can't remember the name.
EDIT : Actually it was just Root Cleaner. It has a batter calibration setting.

If your screen/display isn't the top thing then in most cases you have a problem

This may sound silly, but do you ever turn your screen off, lol.
Just kidding, but that's pretty bad.
Click the screen on and see what your time is. Is that with the Zero Lemon?
Sent from my SGH-I317 using Tapatalk

Either a CPU max run state...or a serious wake lock...or both..
Zero lemon getting drained like that is a serious problem...
I would suggest a "complete" wipe...and the flashing of a rooted stock rom as a test base...
If the device still exhibits the behavior...then a hardware issue may be at Work here...
If the device gets hot to the touch....then get the device to a stock and clean state...so some unmodified testing can take place...
Let us know...g

Even if you leave your screen on, never turn off zerolemon should still last you much longer than 4 hours of screen time. I have one, I get 3 days usage out of it

Let me guess, one of those really cheap Chinese ones with the black and white labels? Those are sometimes okay (barely) and sometimes total crap. For not much more money, try buying an Ankers brand battery.

True, cheaper batteries are often not at all what the label says and perform worse than an oem one that is 4years old, but some are good, only testing the battery will tell
You can test if its the phone/ROM/kernel/apps causing the issue by looking for drainage and wakelocks with apps like better battery stats and watchdog
So the answer could be you need another battery or you need to change something about your phone, but you will need to test to know

Ohhh gosh not enough pocket money to buy a new battery
