I have the battery in October as a second battery in use (service life up to now about 4.5 months), beginning the battery was very good in terms of performance and load, but he now become quite hot during charging, both the shell and the phone. The battery is so hot that I have my cell phone lying down on a handle immediately and unplugged. The original battery against running perfectly.
-> I do not advise to buy, because it is dangerous if the battery goes off.
Unfortunately, the guarantee and warranty for the battery is already expired, but maybe Amazon is just so accommodating to swap the battery.
