Question: Does anybody knows how to fixed the battery issue.Battery does not charge more than 1%.
Document: Do believe the other reviewers when they say the battery takes a long time to charge. Relative to other devices, I agree the battery does take longer than average to charge. However, if you reduce the screen brightness, the battery lasts a lot longer than just 1 hour. Probably more like 2. And the brightness sacrifice is tolerable. I played Angry birds and Fruit Ninja that came preloaded and I downloaded some baby apps like balloon popping etc. All worked great.
Kocaso M1050 Google Android 4.0 4GB 1.2GHz 1GB DDR3 Ram 4GB Rom1080p HDMI Output 3D Games WiFi Front Camera 10.1" Super Slim Tablet PC (Silver)- Not worth the money, this unit only worked for a week and will not take a charge. The vendor of this item and Amazon should pull the product from stock.
You don't have access to take off the back and take out the battery.Plugged into computer to try to resolve issue,  a window explaining that it does not recognize the device popped up on the tablet.Needless to say, It is being returned. Although this may not be a forum to bash Nomorerack.com, I must urge those thinking about purchasing from that site to use extreme caution. Their customer service is hard to get a hold of. They act as if this is isolated.
To start with, the battery won't hold a charge overnight........then it sets it's date to 12/31/09, which I have to set everytime that I want to watch Netflix. Netflix constantly locks up and I have to uninstall it then re-install it......it's also the only video app that even works a little.
I would recommend to definitely NOT buy this. It takes AGES to charge (about 6-8 hours) and then the battery quickly discharges after this (within 90-120 mins) - it even lost 25% charge overnight when it was switched off! I know it's cheap but it takes far too long to charge.
This tablet is the absolute worst, it's slow as can be, it doesnt charge at all, like running in normal settings battery dies in about.. an hour or less and it takes prob six hours to charge the screen is unresponsive as can be this product in my opinion shouldn't be worth $30.00 USD let alone the price it is, if i were you i would not not not buy this do not buy it you will regret it for sure.
I bought one of these needing a simple tablet for scheduling meetings and checking email, this does neither, at least without great difficulty, the battery takes 10 hours to charge and last about 30 minutes, the touch screen is virtually non-responsive. It's a cheap hunk of junk and has served no purpose for me other than a source of frustration and anger.
I've purchased 3 of the SAME model of these online and had to return ALL 3. I lost all my money on 2 of them as they were purchased before Christmas and it is too late to return for a refund. My advise is to NOT buy these. One would not power on at all even plugged in. One would not charge up and would only work plugged in. One was shipped with the battery loose in the unit.......Chinese junk !!
This tablet is the worst one you can ever find. Low touch screen quality, you can't use your finger for your touch has effect, you must use the pen. Very lagging UI, touch screen, and performance.Horrible battery life, you will charge this tablet in almost 4 hours to have one hour battery life.Screen resolution is bad, video playback is so annoying. Please, keep away from this item.
If your looking for a tablet to use more seriously this is not the tablet for you.CONS:  The OS is 4.0.2 ice cream sandwich and is already outdated. The manufacturer provided no screen lock, security lock, password or PIN for protection of personal or sensitive information. The charge time is long and battery use is about 2-3 hours with the screen light lowered. The speaker volume is low but sounds fine with ear-buds or head phones.
