Overnight charging:is this good or bad

Hi, I have read here that some are doing this. What would be the effect of this on the battery life, as it usually takes only about 3 hours to charge to full. Thanks

There's no effect, it's fine. The phone knows when to stop charging.

agreed - I've been doing this with my phone every night since the G1 days with no problems
:good:

No overheating or whatever? Okay thanks. Nice to know that.

the charging micro will turn off supply to the battery when it is 'charged' so nothing to worry about at all

Yeah when the phone gets to 100% it will disconnect until 98% then start charging again.

Unlike me, the phone knows when it's had enough!

I think this is a base android feature, even my TF101 tablet does this when it's on the dock. It'll discharge until about 96% then start re-charging.

All of a sudden....

Gentlemen...all of a sudden, this gadget is taking 10 times more time to charge. Till 3 days ago...it was getting full charged within a couple of hours from 0-100%
All of a sudden, it's like 6 effing minutes for 1%....whats wrong? Have tried removing nd re inserting battery/tried charging from various plugs-sockets...:banghead:

If Your phone is running battery intensive apps its gunna take longer to charge. For instance...if I'm running navigation with music and the screen is on high brightness I will still LOSE power while I'm charging on my trucks USB.

Something wrong with your charger. Try another charger, if it charges ok with another charger then obviously your charger is at fault. Get a replacement from Samsung.

Thanks mate..will try that

Make sure you use the charger provided. The note 2 uses 2mA. Most phones use 1mA.

That would be 2 A and 1 A, not mA!!

Make sure you are using the same cable as provided. One time I changed to a different and longer cable and it took forever to charge.

+1, the longer cable also not able to withstand charge while using the phone...

JB OTA battery life

I've been running the ota rooted JB ROM since it came out. I am not running any tweaks at all. Only difference is that I am rooted. Well battery life at first was awesome I would go 15+ hours with 3.5-5 hours of screen time. Now for the last week I have only been able to get 10 hours with 2.5 hrs of screen time max. want to know if anyone else has noticed this.
Oh and my phone seems to heat up a lot when I am only on FB and texting.

Your best bet when experiencing battery problems is to just do a factory rest , clear all cache and see if that helps. It usually does the trick.
Sent from my SPH-L710 using xda app-developers app

I get atleast 2 days without charging

Don't want to do a factory reset lol
Sent from my SPH-L710 using Tapatalk 2

my battery life has been worse since JB

Update on this. I still only get 2.5 hours on with 12hrs max off charger. This is with ktoonz kernel and mw86's tweaks

That was before I was rooted! Haha!

check any installed app to see if they are using your internet.. for example every time Facebook updates its app.. They decide to change my settings to update every 15 mins..

You could be in the same boat as me. My phone don't play well with ktoonz kernel. Horrible battery life no matter what I did. Went back to stock and I'm back to 4+hours screen on and 15-16 hours off the charger and even longer over wifi

I'll let it go one more day, used the official Samsung charger this time to see if that has some effect on it.
If not I will try stock kernel over the weekend.

You should know these batteries are Lithium ion batteries. So their life decays as time goes on and as you charge them. You may need a new battery

Did you switch back to stock kernel? Any results?

Slow Charging

My phone takes 5 to 6 hours to fully charge. It started about 3 days ago. I've tried Odin back to stock. I've tried different ROMs. I have also tried changing chargers and even a different battery. What can this be. It sucks to have to wait so long for my phone to charge.

It started on liquid with stock kernel then I tried devil kernel and nothing. Then I went Jedi x then to carbon. And now I'm on slim ROM. I haven't changed kernels anymore because I'm getting great battery life on slim but the charging is still slow.

I remember you asked this question about the Perseus kernel also if your running slim 4.2 neak kernel v2.1 has a fast charge setting if on 4.2 download the neak kernel 2.1 and the uneak engine from the play store to utilize all the kernel has to offer

I had slow charging issues on Carbon, but it's been fine on any other rom I've used. I also use NEAK kernel now and no issues here. Rootbox actually works great with NEAK and no charging issues whatsoever. You should give that a try if you don't want to use touchwiz. www.rootbox.ca

What worked for me I just removed the battery and cleaned the contacts of the battery and phone I don't know it might work for u. Good luck.!
Sent from my SGH-T889 using xda app-developers app

Thank you guys for your input. I've been using neak kernel and uneak engine and I wouldn't say my charging is like when I got the phone, but its definitely not taking 6 hours to charge. Its taking maybe 4 now.

They all the same t0lteatt or t0lte. Used both.

Try changing charging cable, the factory one is not good in quality. There's an app that show how many current is taking the n2 when charging. That will give you a glimpse to know what is the cause. Mine was the cable. Hope it helps!

Wife had the same trouble, new cord fixed it... then I had the same issue, new cord, fixed it again.
we went from charging for 6 hours and not hitting 100% (starting from about 50) to going from about 70% to 100% in about 1 hour and still (mildly) using the phone
Change your cord guys, the samsung one stops working so well after a while. also you can use "galaxy charging current" app from app store to see if you are getting good charge levels

Thanks but I stated it wasn't the cord. It charges my s3 perfectly and I've already tried different cords.

Weird battery problem

Ok so I am on frosty v8 rom 4.2.1 I am using saber kernel 45.3 I have tried recalibration of the battery but for some reason when I am charging my phone now it says its charging on the lockscreen but the phone is still dropping power. So I installed battery monitor pro and I have noticed that it says its discharging but while plugged in but the phone isnt running anything in the background.
Will upload some pictures
I think it might be the battery or the charging cable.

He uses saber kernel. And I am using it. But I dont think its rom related. Or kernel related.

It's a tricky scenario. ..
I posted my own observation below yours ...
I get drainage while charging at a low battery% especially while using phone at same time .. This shouldn't be it's like low battery charge% is overriding the charging capabilities.
A phone should gain % while charging regardless of how you consume power least I'd think.
I wanna test this discharge/ charge theory while my phones at 80-90%.

now its really weird the phone is ice cold like 25degree, and the battery monitor pro app says the phone is charging not discharging but it says 0.0%/hr and the percentage is not moving up.. very confused.

I really dont think its rom related. Because I have been using the same rom for the last 10 months.
