Question: Does the battery realy last for three hours?
Document: My son got this for Christmas and it died after only 1.5 hours after having fully charged it and turned it off on Christmas Eve before I wrapped it. We turned off the WiFi and it made the battery last a little bit longer, but not much. Very disappointed in this tablet.
It will burn some heavy milliamps sitting there doing nothing. I set the Noria sleep delay to 2 minutes. I lowered the screen brightness to about 40%, which seems fine to me. I left the Noria running overight, starting with an 83% charge, and in the morning it had an 82% charge so its sleep power consumption is very low. The Noria battery is rated at 2200 mAh, expected to last 3-4 hours.
I have purchased several tablets over the last three years and thought it was time to get a &#34;starter&#34; tablet for my son who is in elementary school. I wanted something that was reasonable in price and met the needs that he has with his school work. I chose this one and have regretted it since the first time I charged it. It is as close to a piece of junk as you can get.
The first day I got the tablet it shut down for several hours and I had to reset it the same thing happened the next day and on day three it shut down and would not turn back on at all. For $120.00  that should've never happened at all. I returned it and spent an extra $70 for a tablet I love. Don't waste your time on this product.
The battery doesn't last long. The machine keeps reseting itself so you have to reset your settings to your preferences.
This is a good starter tablet for younger kids. Works fine. The battery could last a bit longer but all in all like it.
It is good for the price. The battery doesn't last long and apps load slowly. If you close apps that are running it works a little faster.
love the tablet and all the pre installed functions, unfortunately the battery does not last as long as promised, after about 3 hrs. I have to charge it because the low battery warning comes on.
good afternoon I want to say that this product does not last any battery. not last more than 20 minutes is not a good product thoughts about me and that comment as the best. Discontent with this product
Was a great gift! But the screen has a odd reflection! the charger doesn't fit but If you have an Android charger that works perfect! And my last complaint is battery life isn't long. But for a 4 and 2 year old it is perfect!
Answer: It all depends on what you are doing with it
