Battery Performance


The Realme 7i is an Entry Tier Smartphone (less than 200 EURO) powered by the Mediatek Helio G85 chipset, a gaming processor specially designed for game lovers. The Realme 7i is powered by a 5000 mAh battery, and an 18W fast charge, a well-sized battery to offer enough autonomy while playing.

The overall Battery Performance Score is now a global score taking calculations from Battery Life, Power Efficiency and Charging Times.

From the Realme 7i test results, we have given this Smartphone a ViserMark Battery Performance Score of 62. The Battery Performance Label, being nearer 100 indicates that it is one of the best-performing ones and has been ranked in 4th place of the best Battery Performance Smartphones as tested by SmartViser.


Testing Results

BATTERY LIFE - Days of Use

Through the ViserMark test protocol, the Realme 7i battery lasts around 86 hours obtaining a ViserMark Battery Life score of 3.5 Days of Use.

The average ViserMark Battery Life score of an Entry Tier Smartphone is 2.2 Days of Use. This score places the Realme 7i as one of the best Smartphones with great battery life and matches the Wiko Smartphones that dominate the ViserMark Entry Tier ranking. The Realme 7i also has a Super Power Saving mode that gives extra life to the phone when the battery is about to die.


CHARGING TIME - Hours and Minutes

To reach the full 100% the Charging Time was 3 hours and 7 minutes. The average Charging Time is 1:46 for a Smartphone within the ViserMark Entry Tier.

There are a number of power-efficient processors, within today's Smartphones, that are able to cope with the growing number of new applications and can support high-resolution displays without compromising battery life.

Power Efficiency is calculated using Battery Life and Battery Capacity. This is expressed in “Leaves" and reflects a rating between 1 being least and 5 being the most power-efficient.

The Realme 7i achieved an overall Power Efficiency Score of 2.5

  • Best Smartphone for Power Efficiency: Ranking #8

  • One of the Top 5 Entry Tier Smartphones with the Best Power Efficiency



To conclude, the Realme 7i autonomy is higher than most devices in its price range, offering 3.5 days of autonomy through the ViserMark Test Protocol. To compare it with other Low Tier Smartphones, a selection of devices powered by a 3000 mAh battery was conducted expecting them to have Battery Performance scores close to half of the Realme 7i one.

From this perspective, the Realme 7i Battery Performance stands close to other low tier devices like the Huawei Y6 (3020 mAh) (Visermark Battery Performance Score is 51) or the Huawei P Smart 2019 (3400 mAH) (Visermark Battery Performance Score is 47).


ViserMark tests are performed with the strictest protocol in a controlled environment to ensure repetition and consistency powered and automated by SmartViser’s test automation solution viSer. The automation test includes a variety of user actions from calls to social media and periods of standby times.
