I hope its a lot better..I want a battery that will last me quite a bit longer. How much longer do u think?
Ideally a little under 35% longer. ( The stock is 1300 mAh. So, 1750/1300=1.34615... ) Of course, we don't know how either one measured the rated capacities, the variance from battery to battery, etc.
Interestingly, a lot of people with the 1750 are showing something like 300% increase which could suggest there is something wrong with the 1300 stock. ( I'm slowly starting to lean towards this due to several things. First that each time someone with a seidio measures it, it tends to be significantly outside the 35% increase we SHOULD see, but also due to the variance in some of the stock batteries. It seems some people are getting significantly more out of the same battery. )
However, I should mention that we still need a ton more information on all battery types, usage, etc. before we can really figure out what is going on. It could be any one of those things is just a fluke so far.
We really need more people to go over and post their data at:

Good or bad, 1300, 1500, 1750,etc battery...all of it. Include as much detail as you possibly can ( especially if you are outside the apparent norm. such as people with very high awake times.)
