I am having the same problem with my S2
I have two Galaxy S2 phones. One is for every day and the other is just a back up. I got it as a present and did not return it.
My daily one started showing battery charging issues:
It would take a long time to charge.
Battery percentage would go down despite having the charger plugged in.
Then overnight it would show fully charged. I unplug the charger and the percentage goes down drastically.
I tried the charger of my other phone (virtually brand new) and did not notice any difference.
Then I swapped the batteries: I put the back up phone's battery into the problem phone and with either of the chargers it did charge fully and without any drawbacks. What's interesting, the 'bad' battery was also charged fully and speedily on the back up phone with no issues.
I put back the old battery from the nicely charged new phone to the daily phone and after normal usage, I plugged the charger in and the same problem. It wont charge; it is very slow; and the percentage would go down instead of increasing. I repeated the same procedure as described above and it worked fine.
Questions arise:
If my problem battery is dead or dying, why would it charge fine on the new phone? Why would the new phone's battery charge fine on my old phone? But as soon as I try to charge the problem batter in the old phone, problems arise.
Swapping chargers did not make any negative difference.
I am concerned if it is a phone/hardware issue; battery issue or even the charger. I dismiss the charger being the issue.
Do I buy a new battery whilst it is charging fine on the new phone and the new phone's battery is charging fine on the old phone?
Appreciate some inputs, please.
Thanks
