Energizer Ultimate U710S
- Lowest possible price point
- Acceptable for basic communication
- Potentially longer battery life due to less powerful chipset (depending on battery capacity)
- Slow performance for multitasking
- Outdated chipset architecture
- Slow charging speed
Energizer Ultimate U620S Pop
- Significantly faster performance
- Faster 18W charging
- More efficient chipset
- Likely slightly higher price
- Potentially shorter battery life (depending on battery capacity)
- Still a budget device with inherent limitations
Display Comparison
Neither Energizer provides display specifications beyond size, so a direct comparison is limited. However, given the price points, both likely utilize IPS LCD panels. The U620S Pop’s more powerful chipset *could* support a higher resolution or refresh rate, but this isn’t confirmed. Bezels are expected to be substantial on both devices, typical of this market segment. Color accuracy is likely to be standard for budget phones, prioritizing power efficiency over color fidelity.
Camera Comparison
Without detailed camera specs, analysis is limited. Both phones likely feature a primary camera and potentially a depth sensor. The U620S Pop’s more powerful ISP (Image Signal Processor) within the Helio P70 chipset *could* result in better image processing, particularly in low-light conditions. However, the quality will heavily depend on the sensor used, which is currently unknown. Any 2MP macro or depth sensors on either device should be considered marketing features rather than significant photographic assets.
Performance
The core difference lies in the chipsets. The U620S Pop’s Mediatek Helio P70 (12nm) is a significant upgrade over the U710S’s Helio P23 (16nm). The P70 features a more modern CPU architecture – four Cortex-A73 cores clocked at 2.1GHz versus the U710S’s four Cortex-A53 cores at 2.0GHz. This translates to approximately 30-40% faster CPU performance in benchmarks and a more fluid user experience. The P70’s GPU also offers a substantial improvement for gaming. The 12nm process node of the P70 also contributes to better thermal efficiency, reducing the likelihood of throttling during sustained workloads.
Battery Life
Battery capacity isn’t specified for either device, but given the market segment, both likely fall in the 3000-4000mAh range. The U620S Pop’s 18W wired charging is a clear advantage over the U710S’s 10W charging. This means significantly faster top-ups – potentially reducing charge times from over 3 hours to around 1.5-2 hours. While a larger battery capacity is always preferable, the faster charging of the U620S Pop mitigates the impact of a potentially smaller battery.
Buying Guide
Buy the Energizer Ultimate U710S if you prioritize absolute lowest cost and only need a phone for essential tasks like calls, texts, and light social media. Buy the Energizer Ultimate U620S Pop if you want a smoother, more responsive experience for multitasking, occasional gaming, and appreciate faster charging to minimize downtime. The U620S Pop is the better all-rounder.
Frequently Asked Questions
❓ Will the Energizer U620S Pop handle popular games like PUBG Mobile or Call of Duty?
The Helio P70 in the U620S Pop is capable of running PUBG Mobile and Call of Duty, but expect to play at medium settings to maintain a stable frame rate. Don't expect flagship-level performance; the focus is on playable, not maximum fidelity. The U710S’s Helio P23 will struggle with these titles.
❓ Is the 18W charging on the U620S Pop compatible with Power Delivery (PD) or Quick Charge?
Energizer doesn't explicitly state PD or Quick Charge compatibility. It's likely a proprietary 18W implementation. While it will work with standard USB chargers, you'll achieve the fastest charging speeds with the included charger or a compatible 18W adapter.
❓ How much RAM does each phone have, and will that impact multitasking?
RAM specifications are not provided. However, given the price point, both likely have 2GB or 3GB of RAM. The U620S Pop’s more powerful processor will handle multitasking more efficiently even with the same amount of RAM as the U710S, but more RAM is always preferable.
