Help Battery Life on Campus network?

[Aklr]

Hey All, so I have been experiencing issues with battery life on my Samsung Galaxy 5 S for a while now, particularly with how fast battery was draining while I was at school. I'm a full time student in the ophthalmology department and I use the hospital's Wi-fi. It wasn't until I recently went home for a visit that I noticed my battery didn't drain nearly as fast. When I came back to school however I had the same battery problems. Is there a logical explanation for this? Is there something I can do to make it better? Any feed back would be appreciated!

It depends why it's draining. If it's because the cellular signal is weak inside the building then there's not much you can do, though it the 3G signal is weak and the 2G signal stronger then switching to 2G mode might help (if the phone is switching bands all the time that will drain power faster).

You could install GSam Battery Monitor and use that to identify the main power drain - it will also show a graph of the cellular signal level, which would help you spot whether that is a problem.

The other possibility, since you mention WiFi, is that if the hospital WiFi is more complex than your home environment (which is probably just a single router). I'd expect that if the phone is constantly handing-over between different transmitters that would also increase drain.

That's good advice. Thanks very much for that. I will try out GSam Battery Monitor!

As a point of interest, I connected to "StaffNet" wifi instead of "GuestNet" wifi and I just got home (woke up at 6:50 a.m.) and my battery is at 71%. Does this make any sense to you?
