Galaxy S3 post-JB update chaging issues

[Anonymous]

Sorry if this has been covered elsewhere, but I have looked through previous threads and am unable to find what I need to know. Now, the problem...

My S3 has been updated to Jellybean via OTA from Samsung, so I am assuming it is a factory unlocked unit as it wasn't from O2. Since the update, I have had issues charging the phone which weren't present before the update. Using the AC charger yields a charge rate of <2% per hour and charging via USB yields a rate of roughly 8-10% p/h. If I use the phone while it is chargning, the battery life actually drops.

I have been in touch with Samsung, who told me to remove the battery for at least 40 mins before reinserting it and discharging the phone completely. Then charge the phone to 100% while turned off before performing a factory reset. After my doing this, they think the battery is at fault and are going to send me a new one, however, I think this is software related as it seems odd how it's only since the update that the issue has surfaced.

Battery life is between 2 and 4 days with 2 e-mail accounts syncing every hour, WiFi and mobile data constantly enabled and variable internet usage daily - so no problems in the battery life department.

I hope someone can shed some light on the issue at hand, and my thanks in advance for any help given.

Ok i've been away from work for the last few days but been keeping an eye on this post on my mobile browser. 

Last night I took the dive and went out and bought the Samsung Galaxy S3 charger (from an o2 shop) It looks IDENTICAL to the one that came with my phone however.

The cable is slightly thicker (meaning a higher ampage allowance?) and the charger unit is rated at 2 amps as opposed to the 1 amp one that came with my phone.

My battery was down to 14% last night back at home (been charging in hotel rooms for the last few days with a few issues)

And within 2 hours of plugging it in the phone was fully charged. So much faster than the original 1 amp charger.

As someone pointed out I think this is an issue of the 1 amp charger that for some reason came with my device. I only upgraded to this device about 3 months ago now however i'm thinking it could have been old stock perhaps?

Could any o2 staff or anyone knowledgeable shed some light on this?

So my phone now seems to have sorted itself out and now charges to 100% within a couple of hours every time. The battery has finally arrived (after about 2 weeks) but remains unused due to everything working again.

Must have been its 'time of the month'.

Thanks for the input guys, and if I experience any other quirky issues then I shall return to this forum once more. I shall mark as solved.

(Still getting 2-3 days out of the battery, not that I'm trying to induce jealousy at all...)
