PCMark test
The PCMark test evaluates the time it takes for a smartphone’s battery to fall under 20 percent from 100 percent capacity. We set both phones at 80 percent brightness level before commencing the test. At the end of the benchmark test, the CMF Phone 1 took 15 hours and 11 minutes to fall under 20 percent capacity, while the Realme P1 registered a time of 16 hours and 20 minutes to achieve the same. Based on the benchmark results, the Realme P1 should offer a slightly longer battery life.
Winner: Realme P1
Video streaming test
For the streaming test, we play the same YouTube video on both devices at 50 percent brightness and volume level to gauge their respective battery drain. Both the CMF Phone 1 and the Realme P1 registered a battery drain of 3 percent each during our test, thus the round ends in a tie.
Winner: Tie
Gaming test
For the gaming test, we played COD: Mobile, BGMI and Real Racing 3 on both phones for 30 minutes each to log their battery drain. The CMF Phone 1 registered an aggregate battery drain of 21 percent (7 percent average), while the Realme P1 registered an aggregate battery drain of 19 percent (6.3 percent average). This round was won by the latter by a narrow margin.
Winner: Realme P1
Charging speed
Both phones come with different fast charging support. Unlike the Realme P1, the CMF Phone 1 does not include the charging brick inside the retail box. With a compatible charger, the CMF Phone 1 takes about 63 minutes to recharge from 20 percent to 100 percent battery capacity, while the Realme P1 takes 48 minutes.
Winner: Realme P1
Verdict
The Realme P1 is the clear winner in the battery comparison against the CMF Phone 1. It has better synthetic benchmark results, has a lower battery drain while gaming and offers faster charging speed compared to the latter. The cost of ownership for Realme P1 is less as you don’t need to purchase the charging brick separately. If battery life and charging speeds are important aspects for you, the Realme P1 is the better choice between the two.
Having said that, we would like to reiterate that CMF Phone 1 is also a competent smartphone in this price segment. The phone offers better performance output and comes with a unique design that can be further customised to suit your preferences. Also, it was not much behind the Realme P1 in terms of battery life and charging speeds. If battery life and charging speeds are not as important to you, you can consider the CMF Phone 1.
