I recently left Samsung and decided to try out Nexus 4. I actually planned to test it out so I kept the plastics on the charger and everything, and left everything in the box because I want to sell it for the Nexus 5. Anyways, I've used it for exactly a week now and it's been working just fine, but last night was the second time I left it charging overnight. Since I kept all of its stuff in the box, I use the charger from my Nexus 7 to charge it. It's been working fine so far, but today I woke up from my alarm, took my phone off charge and it worked perfectly. I went back to sleep with the phone beside me and when I woke up, it wouldn't turn on. Anyways, I got really worried and eventually it safe booted when I pressed power + vol. down. I pressed "Start" and now it's up and running but when it powered back on, it showed 85% battery instead of 100% considering it was on charge for about 8 hours. I know this isn't because of battery hibernation because I put it on charge while it was at about 4% I believe. I've looked around everywhere online and I can find people with similar problems but all of them have something like the phone going into hibernation or such. But Mine did not do anything like that. Can anyone please explain why this happened? The phone still has warranty but I really can't afford to go without a phone for 3 weeks if I send it in. Thanks so much!!!
P.S. It's running the latest KitKat, I've never rooted it, flashed it or anything like that. I am running the Google Experience Launcher.
Edit: I read that Nexus 7 chargers use 0.8 more current that the Nexus 4 chargers. Can that be the case? Thanks again guys!
