Default Seidio Extended Life battery

Hi Board,

I have purchased the Seidio Extended life battery (2600mAh) about 1 week ago and i do not feel it is performing as expected.

Here are the issues i am facing:-

1.) The phone takes about 1 hour to report fully charged (similar to standard battery), but if i unplug the charger then re-insert, the battery charge is reported at 60%.

When the battery reaches 100% again, i repeat the same process and this time the battery reports as 70%.

This repeats until the battery is "actually" at 100%

2.) The battery seems to drop charge irregularly, the first 10% is lost after a very short period of time (4 minutes on the last check!)

3.) Once the battery reports as being down to 20%, if i re-boot the phone, it then reports charge of 60% again and the process starts again.

I have enclosed 2 attachments to support this information, the image file is a graph i pulled from an app called "Battery Graph", as you can see, the battery level does not drop on a smooth basis, if it was working correctly i would expect a smooth curve, not sharp drops.

The second attachment is a zip file which contains an excel spreadsheet showing the full breakdown of the battery % drop during yesterday.

I have used an app called Battery Refresh to fully drain the battery probably now about 6 or 7 times (as recommended on the back of the battery).

Has anyone else got this battery and is having a similar issue?

Thanks in advance.
