Hi, battery life is about on par for 3200 mah actually imho,, its ok but not great as any smart phone while not using wifi disable it at night while sleeping , it saves the trickle drain , the good is that u can still use the tablet while on charger, some u can not ,, as for the battery calibration i see no biggie there ,, weird but no biggie , the other stuff u mentioned warrants a return imho ,, as for removing the back cover i just simply popped it off starting from the usb side corners and worked it around , it unsnapps sort of like a samsung galaxy s phone cover backing , lol and it snaps right back in along the edges around the whole unit , i have removed it several times with not issues, i like that about it
cross your fingers i ordered 4700 mah batteries , i had to order 6 of them and they are custom made ones for the dimensions i have for this tablet ,, it is about all the battery u can squeeze in there i hope its not too thick but i see a little play room according to my measurements i cant wait till the batteries arrive im hoping this will blow the doors off of the nexus7 and ipad battery life
also popped open a few of my old cell phones and found a small speaker that will work as a secondary ,, there is a empty spot to add another speaker on the circuit board btw ,, or u could just tie into the existing speaker , im not really concerend here just experimenting and hopefully making it one of the best 7 inch tablets, it has so much potential as compared to all the others i have had in its class, that is why im spending my money and time on bigger batteries and such i love the feel and size format of this tablet ,, the weight is so light compared to others and size is small as compared to some others and the screen is so nice and crisp as compared to others ,, for me its perfect for its class , just concerns me that u have issues that i dont ,, and i am going to purchase another one as soon as it is in stock again
Thanks for the info, managed it in the end. I seem to have fixed my microphone issue! After locating it at the back side of the board next to the headphone jack, I simply tweaked it around a bunch while recoding to see the input level. At one point it went right down to no input at all. I checked the recording and it had indeed been fixed!
Now my only worry is that it will develop the problem again, rather soon in fact because I couldn't actually see the microphone physically move but I must have been doing something!
Good luck with the battery thing. I wish I knew how to solder. I also wish I had a soldering iron actually, I'd probably be stupid enough to give it a go even though I've never done it before. Sort of like trying to fix the microphone
Red arrow points to location of mic if anyone else needs to try this:
Oh and it should be noted that it still has VERY minor weird sounds when charging still but it's almost inaudible.
Managed to film my video issue:
It's pretty rare so I'm willing to live with it, I just hope it doesn't get any worse.
It doesn't seem like a hardware problem because it only happens when in a browser and when typing. Also notice it only happens when the suggestion box changes. Weird.
