I have a Lumia 820, and use a lot of data on it as well as plenty gaming. Of course, fast battery drainage is a result. The battery always gets eaten up by mid-day every day. I was thinking about getting some extra batteries, but I am not sure if it might bad for my phone?

Thanks in advance!


If you are running out of battery where you cannot finish the day without the phone dying, having a replacement battery you can swap out will not damage the phone at all as long as you purchase a suitable replacement. In fact, this has been a common practice amongst business users and a complaint about many high end phones which tend to not have replaceable batteries.

Nokia even sells portable battery chargers if you do not want to carry an extra battery around.

No it won't. I don't have a Lumia 820, but I do have an extra battery that I switch to when my Lumia 822 dies. The battery life is much improved, and my phone still work good enough for me now.
