Energizer Ultimate U505s

  • Extremely affordable price point
  • Functional for basic smartphone tasks
  • Potentially longer battery life (depending on capacity)

  • Outdated and slow Mediatek MT6739 chipset
  • Slow charging speeds
  • Likely limited software support

Energizer Ultimate U620S Pop

  • Significantly faster Mediatek Helio P70 chipset
  • 18W fast charging support
  • More responsive user experience

  • May be slightly more expensive than the U505s
  • Potentially smaller battery capacity (depending on specs)
  • Still a budget device with inherent limitations

Display Comparison

Neither device's display specifications are provided, so we must infer. Given the price point, both likely utilize IPS LCD panels. The U620S Pop, being a newer model, *may* benefit from slightly improved color accuracy and viewing angles. However, the real differentiator will be software optimization. The U505s, with its older chipset, may struggle to efficiently render more complex UI elements, potentially leading to a less fluid visual experience. Bezels are likely substantial on both devices, reflecting their budget nature.

Camera Comparison

Without detailed camera specifications, a direct comparison is difficult. However, it's reasonable to assume the U620S Pop benefits from the improved image signal processing (ISP) capabilities of the Helio P70 chipset. This could result in better dynamic range, noise reduction, and overall image quality. The presence of a 2MP macro camera on either device is largely a marketing gimmick; its utility is limited by the low resolution and lack of optical image stabilization (OIS). The main sensor size and aperture will be the key determinants of image quality, but this information is unavailable.

Performance

The performance gap between the Mediatek MT6739 in the U505s and the Helio P70 in the U620S Pop is substantial. The MT6739's quad-core 1.5 GHz configuration is significantly outmatched by the Helio P70's octa-core setup (4x2.1 GHz Cortex-A73 & 4x2.0 GHz Cortex-A53). The Helio P70's architecture, built on a 12nm process, offers superior power efficiency and processing capabilities. This translates to faster app loading times, smoother multitasking, and a more responsive overall experience on the U620S Pop. The U505s will likely exhibit noticeable lag when handling demanding tasks.

Battery Life

Battery capacity isn't specified for either device. However, the U620S Pop's 18W wired charging is a significant advantage. The U505s likely supports slower charging speeds, meaning a considerably longer time to reach a full charge. While a larger battery capacity on the U505s *could* offset the slower charging, the Helio P70's improved power efficiency in the U620S Pop means it will likely deliver comparable, if not better, real-world battery life despite potentially having a smaller capacity.

Buying Guide

Buy the Energizer Ultimate U505s if you prioritize extreme affordability and only need a phone for basic tasks like calls, texts, and light social media. It's a functional device for those on a very tight budget. Buy the Energizer Ultimate U620S Pop if you value performance, faster charging, and a more future-proof experience. It's ideal for users who enjoy occasional gaming, streaming, or running multiple apps simultaneously.

Frequently Asked Questions

❓ Will the Helio P70 in the U620S Pop handle popular games like PUBG Mobile?
The Helio P70 is capable of running PUBG Mobile, but expect to play at medium settings to maintain a stable frame rate. The MT6739 in the U505s will struggle significantly with PUBG, likely resulting in a choppy and unplayable experience.
❓ Is the 18W charging on the U620S Pop compatible with any USB charger, or do I need a specific one?
The U620S Pop supports standard USB Power Delivery (PD) and Quick Charge protocols. Most modern USB chargers capable of delivering at least 18W will work, but using a charger specifically designed for PD or Quick Charge will maximize charging speed.
❓ How much storage does each phone have, and is it expandable?
Storage capacity is not specified. However, budget smartphones often include microSD card slots for expandable storage. Check the product listing or specifications to confirm if either device supports microSD cards and the maximum supported capacity.
❓ What Android version do these phones ship with, and will they receive updates?
The Android version is not specified. Given the budget nature of these devices, expect a relatively older version of Android, potentially with limited or no software updates. Energizer's update track record is not known for being extensive.
