Another very impressive aspect of the ZenFone 5 LTE is the battery life. Powering things is a 2110 mAH unit, which doesn't sound like a lot – but is very capable.
We found the battery breezed through a day's use. With automatic brightness on, as well as constant auto-sync and WiFi/mobile data enabled, the ZenFone 5 LTE lasted a day and more.
We didn't turn anything off and with our regular usage, the phone often had 30-40% battery capacity left by the evening.
An argument could be made that now we should be expecting a two-day battery life from modern smartphones, a standard set by the Sony Xperia Z3 – so by that same standard, the ZenFone 5 LTE falls a little short.
