The OPPO A78 5G promises a solid battery experience, but how does it perform in everyday scenarios like gaming, browsing, or video streaming? In this OPPO A78 5G battery test, we dive deep into screen-on time (SOT), gaming drain, and charging speeds, so you know exactly what to expect.
Battery Capacity and Charging Specs
Before we jump into performance, here’s a quick look at the battery and charging specifications:
| Feature | Specification |
|---|---|
| Battery Capacity | 5000 mAh |
| Charging Support | 33W fast charging |
| Screen Refresh Rate | Up to 120Hz |
| USB Type | USB-C |
| Estimated Full Charge | ~70 minutes |
With a 5000 mAh battery, the OPPO A78 5G is designed to handle long hours of usage, whether it’s work, entertainment, or gaming.
Screen-On Time (SOT) at 120Hz
One of the key highlights in our OPPO A78 5G battery test is how the device handles a 120Hz display.
-
On regular browsing and social media usage, the phone delivers 7-8 hours of SOT at 120Hz.
-
Streaming videos or watching YouTube continuously brings 5.5-6 hours of SOT.
-
For light users who stick to 60Hz, the SOT could easily stretch past 9 hours.
Maintaining a 120Hz refresh rate naturally consumes more battery, but it keeps scrolling and animations silky smooth.
Gaming Battery Drain
Gaming is often the most demanding activity for a smartphone. Here’s how the OPPO A78 5G fares:
-
PUBG Mobile / Call of Duty: ~15-18% battery drained per hour at medium settings.
-
Genshin Impact (high settings): ~22-25% battery drain per hour.
-
Temperature: The phone warms slightly during extended sessions but remains comfortable to hold.
A 2-hour gaming session will typically consume 30-50% of the battery, depending on the game and graphics settings.
Charging Performance
Charging is where the OPPO A78 5G stands out in its segment:
-
0% → 50%: ~30 minutes
-
50% → 100%: ~40 minutes
-
Total charging time: ~70 minutes with the 33W charger
Even if you’re in a rush, a quick 15-minute charge can give around 20-25% battery, enough for light usage until you reach a full charge.
Key Takeaways
-
The OPPO A78 5G battery test shows long-lasting performance for daily use.
-
120Hz refresh rate slightly reduces SOT but ensures smooth visuals.
-
Gaming drains the battery faster, but a full charge easily lasts multiple hours of heavy play.
-
Fast charging support ensures minimal downtime.
FAQs
1. How long does the OPPO A78 5G last on a single charge?
With moderate usage at 120Hz, expect around 7-8 hours of screen-on time, while light users at 60Hz could get 9+ hours.
2. How fast does the OPPO A78 5G charge from 0 to 100%?
It supports 33W fast charging, taking roughly 70 minutes to reach a full charge.
3. How much battery does gaming consume on OPPO A78 5G?
Casual games drain about 15-18% per hour, while heavy games like Genshin Impact can consume 22-25% per hour.
4. Does using 120Hz significantly impact battery life?
Yes, higher refresh rates use more power. Reducing it to 60Hz can extend screen-on time by 1-2 hours.
