My phone has found a real facelift with this new battery. Not only, I found a range of about 5 days (with regular use), but also my phone is much more reactive than before. I think my old breathless battery should deliver a more proper tension, making the device very slow. Every time I pressed a button, I had to wait a long time to get reaction. I put it down to an internal memory overloaded, but not all. The battery change everything settled. This makes me save money, because I plan not to change phone yet.
Very happy to have a new battery for a device that is 7 years old!
