The larger the number the longer the battery will last.
1500mAh will last longer
Yes.
1500mAh
1100 mah is the battery capacity, the shape and size will depend heavily on the model of battery.
1500mAh standard Lithium Ion rechargeable battery.
Radio Shack or an electronics store would be the first places to check
depends on you charge rate. if you are charging at 1.1A (1100mA) it will take 1 hour
No problem to use the 1100mAh in place of the 1000mAh battery. Mah is like store rooms that have varying sizes. As long as the voltage remains the same (the doors of the store rooms are of the same width and height), the battery with a higher mAh can be used.
i would recommend a smart charger for your batteries
i9001 is upgraded i9000, so it is newer. Changes are: processor is not 1.4GHz single core vs 1GHz in older model (hummingbird -> snapdragon). GPU is now Adreno 205 (instead of PowerVR SGX540). Battery is better 1650mAh (instead of 1500mAh) Metal back GPU is only step back, all other are improvements.
It means it has more power.If it fits in your phone it should work.But look where the battery goes it might say there is a may battery you can put in it.
Just a little under an hour for 1100mAh-2200mAh batteries but probably 2 hours and up for bigger batteries. I charged 2 1600mAh batteries (1 being 8.4v an the other being a 9.6v) in under 2 hours.
Depends on the drain. if the drain is 1500mAh it'll laso one hour before the voltage drops too low. If the drain is 500 mAh it'll last 3 hours. 150mAh, 10 hours 3000mAh, 0.5 hours.
