I bet you waive right to participate in the lawsuit.
Get $50 off a battery or ...? in the future.
Be careful what you sign.
After the class action attorneys take their share you would probably be lucky to get 50 cents.
My wife’s used but nearly perfect Samsung S4 cost us just $50 last month from Groupon. Extra batteries cost around $5 and take about 30 seconds to change.
Actually sounds like a good deal. Even if I don’t swap the battery, I would rather have slower performance than my phone setting my pocket on fire.
