iPhone shuts down randomly when asked "too much"
Hey all !
I've been using my iphone 3GS for about two years now, and it started shutting down randomly a few months ago. It keeps getting worse and worse.
It usually shuts down when I'm trying to access the web (via app or Safari), but it also crashes when I'm done with a call, or when I listen to music. The thing is I can't boot it back on without connecting it to power.
I don't know if it could be the battery, because sometimes it holds the whole day with no particular issue...
What do you guys think ? :)
Thank you !
