Battery charging problem JB stock

[memz180]

Hi guys,

My phone is on UAE official
Just updated from ics to jb using kies and the charging is taking forever like 7% per hour

While on charge if im using the phone it actually is decreasing the battery instead of charging.

Checked using the current app the charger is supplying 1amp tried various cables and chargers etc and same

Would I need to factory reset or wipe cache after an official update.

By the way on ics charge time is perfect so not hardware fault.

Any reply would be great

Cheers

Been said in several other threads that this can happen if the phone wasn't on 100% when upgraded - maybe it removes battery stats. Apparently after the first full slow painful charge its reverts back to normal. I guess its trickle charging so not to damage the battery. Say battery was 50% when updated - it thinks this is full charge - once you do actually fully charge it the phone then re-learns the actual full battery in stats and is ok.

Not sure if this is 100% or not though, i made sure i was fully charged when i updated last night.

All you can do is try and see if its back to normal after a long lengthy first full recharge

Yes that could be the case due to updating at around 85 percent.

Thanks for the great info

What explains the charge decreasing while on charge on use ??

Anyone ??

Ok so I changed the original charger that has the usb input with the extension cable. This is the 1amp charger the red led looked dim using this on JB rom

Now I used the 500ma output direct wall charger with no usb input all in one charger and the red led is full bright like ICS rom and now charging while using phone and charge rates are back to normal

anyone know how to fix usb charger thinking its not AC more like charging from pc usb ??

Cheers

I don't know what really is happening but my phone started to charge reeeeeallly slow in the last two days. ( I got JB over the air a few days back).

It's for example charging right now and as soon as I start to use it while charging, the battery percentage goes DOWN.

I never had this before. On ICS I was able to easily get through 2 days (I mostly have power saving feature on, since everything works great even in power save mode).

What the hell is happening here.

I used to have this problem, too. I fixed it by turning my phone off and letting it charge to 100%. After that, it would charge and discharge as expected again.

I have the same problem,

But I have a temporally solution , I charging my mobile with my old charger for galaxy s2 ( which is direct to wall ) , it will charge fast as ICS rom before ( 1-100% 2:20 mnts)

I think there is a problem in JB rom, the mobile thinking the original charger (with extension USB cable) it is charging from computer ... so it is really really slow , plus it is not charging after 90%


any how .. the mobile charging well when it is off.!!!

This my experience

Yes like you im using direct charger 500mA and its charging while I use phone and I get full charge from 10% to 100% in about 2 hrs and 50 mins

For a second I thought I was the only one with this issue turns out many of you guys noticed this problem aswell

thanks for the all the input
