[Shield Tablet Q&A, Help & Troubleshooting] Hoover1979:
Like idling at the home screen or in Sleep Mode!

My Shield Tablet has had nothing but battery issues, since mine arrived almost a year ago!! I am expecting a new one in about a week as my current one is part of the recall. I lose charge even idling on the home screen or in sleep mode. Even with WiFi and Bluetooth switched off it drains. I can only keep a charge when plugged in by locking the frame rate to 20FPS. A gaming tablet that has to be locked to 20FPS?!!!!! I lose charge with the stock standard 2.1a charger that came with it and also with the charger for my Shield Portable (Also 2.1a) and I still lose charge with a 2.4a charger and it takes twice as long to charge back up with the 2.4a! My shield portable never lost charge while plugged in...... Until it upgraded from Kitkat to Lollipop. It is also displaying the same woeful battery performance as the Tablet. There must be a flaw in Lollipop (Or at least Nvidia's version of Lollipop) after my portable went from Kitkat to Lollipop it also keeps losing charge on chargers between 2.1a to 2.4a. Of course Nvidia is in denial as usual, just like they are in denial about the fact they broke Gamestream several updates ago and as a result Input lag is unbearable (They still advertise Gamestream as "Minimal Lag" ROFL!) even on high speed connection and Gamestream ready 5Ghz Router (ASUS RT-AC68U on 100Mbps DL / 40Mbps UL - Best connection possible in Australia via NBN). The Gamestream issue is not being recognized as Nvidia are making like Ostriches and burying their heads in the sand, and I fear that is also the case with the woeful batteries and firmware that is not optimized causing the batteries to drain worse, even while charging.

When I first bought the tablet it was running Kitkat. It kept a full charge on all apps (Like the portable) and it charged surprisingly fast for such a device. Now it takes for ever to charge (I can't believe it took nearly 4 hours to charge from 85% to 100% with the tablet switched off and hooked to a 2.4a charger! The tablet never gains a solitary percent when on, even in sleep mode and it drains, again and again. I have tried factory resets to no avail and I hope the new one with the B01 Battery (Mine currently has the infamous Y01 Battery) at least holds a charge when on and hooked up to the charger. But from my experience with Nividia's issues and their denial and complacency. I sincerely doubt it would perform any better and I am worried it will perform even worse.

I wonder how the Shield X1 Android TV would work as it does not use batteries. Is it compatible with Australian 240v current? I am sick and tired of Shield devices using batteries. I am really pi**ed about my Portable getting the same issue after going to Android 5.1.1 It WAS great for endless hours of non-stop gaming while plugged in, not like the tablet it drains from 100% to 0% in less than 3 hours without the framerate crippled.) adjusting the cores and CPU frequency makes no difference for me. If I only use 2 cores, the lowest CPU frequency and unlocked 60FPS framerate, the battery drains just as fast, if the framerate is at 30fps it drains but much slower, at 60fps it is a power hungry beast drains power like a police officer downs donuts.

I have been using Nvidia products since my first Riva TNT2 back nearly 20 Years ago, I was always satisfied, and I am still with the PC Graphics cards, but I don't want to buy another Shield Device unless it does not use batteries (I am hoping getting the X1 android TV means I can play games no other android can competently run or run at all, Like my favorite games at the moment "Dead Effect 2" and "Unkilled").
