iPhone 5s battery
Hello, I just got an iPhone 5s, 64GB and i think it has a battery problem or I am just being paranoic. If the phone is in standby the battery lasts more than 1 day, I usually lose 2-3% during night, now the real thing is when i start using 3G or Wifi + facebook, messenger, instagram, the battery drains kinda quick, i lose 1% in 2-3-4 minutes, sometimes it happens to have battery drops from( let's say ) 70% to 65% all of a sudden, I run the 9.2.1 iOs ( i read some things about software affecting the battery life ). My last phone had a 2500 mAh battery and I think im not used to how things work on an iPhone, I'm not even thinking to give this phone because I'm **** addicted to it. An external battery would be a good choice IF there is no solution to my problem? Charging time its around 2 hours and half starting from ~20% to 100%. I-ll post a picture with the battery life and stats. Thanks.
iPhone 5s, iOS 9.2.1
