Idk why but my Nexus 10 has been really off now. I been using stock charger everyday and my charge times has always been around 5 hours and a half to go from 0% to 100%. Now its gotten ridiculous. My charge time going by 5% per hour would mean 20 hour charge time. I thought its been weird that lately when I have it plugged in and running some minor browsing at the lowest brightness my battery percentage was still going down but I thought it was just crappy battery life after android 4.3. So I ran a test today where I set timers where I would check my charge times on every hour and base it off what my previous charge times where. the results are terrible from my previous test when i first got this device
