Battery life test

The Zenfone 2 ZE551ML is Equipped with a 3,000mAh battery, which is sadly not user-replaceable one on Despite being the back Removable. This sort of capacity is about average for a 5.5-inch smartphone.
While the Scorecards Projects omit the standby times, our procedure or of includes Measuring Those as well and they 'are calculated in the overall rating. Our tests Revealed that the two can Zenfone burden much as 10 days in standby-when a single SIM card used this housing drops to about 8 and a half days-when-you pop in a second SIM. Voice calls will drain your battery in a bit under 16 hours that a respectable achievement as well.
Video playback longevity is nothing special but at 8 and a half hours it's adequate.

What that does is keep the selected application in view Regardless of taps on the capacitive buttons. It's a bit fiddly to get out of Requiring a press-and-hold on the back and task switcher buttons simultaneously.
