Battery For Samsung Galaxy E7
BATTERY Non-removable Li-Ion 2950 mAh battery
Talk time Up to 18 h (3G)
Music play Up to 88 h
The Samsung Galaxy E7 is quite heavily equipped in the battery department. Its cell packs 2,950mAh worth of juice, as opposed to the Galaxy A7's 2,600mAh. That one managed rather good numbers in the battery autonomy tests, and with less than half the pixels, we should expect the Galaxy E7 to perform even better.
It didn't quite turn out like that. While the 15 hours of video playback are remarkable, the 8 or so hours of web browsing are only average. At around 20 hours, 3G voice calls are also on the positive side.
We do measure standby times as part of our battery test routine, and while they're not explicitly stated on the scorecards, they are taken into account in the overall score. With a single SIM inside, the Galaxy E7 managed about 12 full days, and that dropped by a day when we popped in a second SIM card.
