I have now been using this phone for 11 days. Here's what you should know, out of the box the phone was pristine. I looked long and hard to find a blemish or defect, there was none. This looked like a brand new phone. Day one of using the phone I was highly unimpressed by it's battery life. The battery did not hold a charge for even half a day. I didn't believe Samsung would sell a phone with that bad of a battery OR this phone was defective. I did some research online and it seems this is the number one complaint about this phone. This is my 1st phone that has an ADAPTIVE BATTERY. I followed some advice online. Let the phone download all the updates etc..the 1st day or 2 this sucks up major battery power. Day 2 and 3 i kept my eye on the battery usage in the system settings. Until day 3 it said it was still learning my usage, once that went away the phone battery worked so much better! I mean don't get me wrong, I got rid of some apps I don't use, changed some settings to save battery life etc. My battery lasts the whole day now with regular use. The phone automatically puts apps to sleep when not in use so that def saves some battery power. All in all I say buy the phone. If you don't like it you have 60 days to return it. I do not buy expensive top of the line phones, I need a cost effective option for reg text, calls, music, browsing and this one hits the mark. I use the speakerphone for work calls and they are crisp and clear. The camera is much better than my A20. As of day 12 I give my new phone a score of 8 out of 10.
