How many photos fit in 1 GB?
About 200 to 400 phone photos of 2.5 to 5 MB each.
How long does 1 GB last for browsing?
Light browsing and messaging can last days or weeks, while HD video streaming can use 1 to 3 GB an hour.
Is GB the same as Gb?
No. Gb means gigabits; 1 GB is 8 Gb.
Why does my data bundle run out faster than expected?
Apps update in the background, videos play automatically and photos sync to the cloud. Check data usage in your phone settings to see which apps use the most.
Does a bigger phone storage size cost more data?
No. Storage size and mobile data are separate. Storage is space on the phone, while data is what you download over the network.
Is it worth buying more storage?
If you shoot lots of video or keep many apps, yes. Video at high quality can use several hundred megabytes for each minute of recording.
How many hours of video is one gigabyte?
Roughly one hour at standard definition, or about twenty minutes in high definition, depending on the service. Lowering the quality setting in the app makes a bundle last longer.
How much storage does an app take?
Small apps may use under one hundred megabytes, but games and social apps can grow to several gigabytes as they store updates, media and cached data.
What is the difference between storage and memory?
Storage keeps files when the device is off. Memory, or RAM, holds what is running right now and is cleared when the device restarts.
