Help S3 continued battery problems

[oneepicboss]

I have a galaxy s3 ive tried every possible thing you can think of to ssve battery it only lsts 8-10 hours. ive contacted Samsung and tmobile with no help at all. are there any extended batterys that are thr same size as the stock battery

Most that are the same size will only add about 30 minutes to the life. The original battery is 2100mAh and the extended the same size is 2300mAh. For anything that would really increase the time on is a 3500mAh and above.

That said if you post what you have tried to help reduce the battery drain someone here may be able to help increase your usage. Give details as to what is using the battery and such also.
