A good smartphone lasts about 10 hours on the Tom's Guide battery test, which involves continuous web surfing over cellular networks. A great phone lasts over 11 hours, and a spectacular phone approaches or passes 12 hours. The Motorola Razr does not do any of those things.
In fact, Motorola's foldable phone turned in the shortest runtime — by far — of any smartphone in the last few years. Granted, we were not expecting a lot from this foldable phone's battery, which has a capacity of just 2,510 mAh.
The result? The Razr lasted a mere 5 hours and 54 minutes, about 6 hours behind phones with the best battery life. Yikes.
Motorola Razr battery life vs competition
|Phone||Battery size||Battery life (hrs:mins)|
|Motorola Razr||2,510 mAh||6:08|
|Pixel 4||2,800 mAh||8:03|
|OnePlus 7T||3,800 mAh||8:47|
|Galaxy Note 10||3,500 mAh||9:10|
|Pixel 4 XL||3,700 mAh||9:42|
|Galaxy S10||3,400 mAh||10:19|
|iPhone 11 Pro||3,046 mAh||10:24|
|Galaxy Note 10 Plus||4,300 mAh||11:09|
|iPhone 11||3,046 mAh||11:16|
|iPhone 11 Pro Max||3,969 mAh||11:54|
|Galaxy S10 Plus||4,100 mAh||12:35|
To put the Razr's endurance in perspective, the 2,800-mAh battery in the Pixel 4 lasted a fairly poor 8:03. And that's more than 2 hours better than the new Razr. Other Android phones that are mediocre in the battery life department include the OnePlus 7T, but its runtime of 8:47 looks epic in comparison to the Razr.
But what about the Quick View display?
To be fair, the Razr isn't designed to be used open all the time. That's why it has a Quick View display up front that you can use when closed. This panel comes in handy for checking or responding to notifications, snapping selfies, making mobile payments, controlling music and interacting with Google Assistant.
It would seem that because of all the components necessary to make a foldable phone, Motorola simply didn't have room to stuff in a larger battery. It's simply one of the trade-offs for having such a sleek design.
If the rumors are true, Samsung's Galazy Z Flip foldable, which has a similar design to the Razr will pack a bigger 3,300 mAh battery. But it will also have to power a larger 6.7-inch display.
Overall, the Motorola Razr's battery life is one of the biggest reasons to avoid this $1,500 phone, unless you plan on using the Quick View display a lot.
