Here are my tests for Samsung Galaxy Tab 7, model T280, on what concerns to battery life:
Standby time, WIFI off: ~250 hours
Standby time WIFI on: ~190 hours
Radio via internet : ~30 hours
Video via internet: ~6 hours
In standby it is a disappointment when compared to model T230 - while T230 loses 3% of battery charge, this new T280 loses 7%.
Comparison tests with video and audio between T280 and T230 yet to be performed.
Does this tablet have a 3g /4g sim card slot. Its not really mentioned in the Samsung product description.
Anonymous, 17 May 2017Anyone can confirm voice calling is available with this model...Yes of course, it's calling tab and it's micro sim and debated slot for memory card. it's 4g set
Recommended for light users and easy to do tasks. Browsing, social media, light casual games. Great value for its price. Awesome battery life.
This is great tab. Very goog battery life, good speed, genuine product and cheap price. Thanks.
Xtasy4ever, 06 Apr 2017Worse tablet ever made by Samsung. Touch response is mediocre, software lag, hard to use it fo... moreThe best tablet made by tablet so far. Haven't experienced all those problems you talking. It's worth $102
