Probably best for trips or going to areas with weak cell coverage.

I lost coverage at the same spot with the Anker battery on as without it

I drove through an area in rural central Texas where I have always lost cell phone coverage

One remark I'd like to make is that we live in an area that has spotty and poor cell coverage so that chews up battery more quickly, so if the batteries are lasting up to 5 days without having to be charged, that is a GOOD battery

TPU Case-------------Coverage - Excellent all around device coverage that is snug and raises above the screen.

The phone now works exactly as it is supposed to!If you remember Nokia phones from a decade ago that lasted a week on one charge, this battery will remind you of that long-forgotten feeling.

I didn't see any changes in performance of the device or anything that is not working as it was before start using the battery.

lots searching during the day with the screen as bright as can be for 3-4 hrs

Works great, only complaint is that the case doesn't hug my phone as tightly as I would like.

I do recommend this battery as I can go days without recharging.

Usually their network is pretty stong in our area with comprehensive 4g service but with this battery I have low bars on 4

But the reception goes from 4G to 3G & my hot spot does not work.
