Moto G57 Power vs G77 Power 5G: Specs That Matter

Choosing between the Moto G57 Power and the Moto G77 Power 5G comes down to one key question: which specs actually affect daily use. The G77 Power 5G wins on processor, display refresh rate, and software longevity, while the G57 Power holds a slight edge in battery capacity and price. For most buyers, the G77 Power 5G is the better investment because its faster chip and smoother screen will keep it feeling current for years longer.

Background: Where These Phones Fit

Motorola’s Power line has always targeted budget buyers who prioritize battery life above all else. The G57 Power launched as a 4G-only device in early 2025, offering a massive 6000 mAh battery and a 120 Hz display at a very low price. The G77 Power 5G arrived later in the same year, adding 5G connectivity, a more efficient chipset, and a faster 120 Hz panel while keeping the same 6000 mAh battery. Both phones share the same design language: a plastic body, a punch-hole selfie camera, and a dual rear camera setup that includes a 50 MP main sensor.

The key difference is not just the 5G radio. The G77 uses a newer MediaTek Dimensity 6300 processor, while the G57 relies on the older Dimensity 6300’s predecessor, the Dimensity 6100+. That single change affects everything from app loading times to gaming frame rates and battery efficiency.

Processor and Performance: The Real Divide

The processor is the single most important spec when comparing these two phones. The G77 Power 5G ships with the MediaTek Dimensity 6300, built on a 6 nm process. The G57 Power uses the Dimensity 6100+, also a 6 nm chip, but with slower CPU cores and a weaker GPU.

In practical terms, the Dimensity 6300 scores roughly 15-20% higher in multi-core benchmarks. That translates to:

• Apps open about half a second faster on the G77
• Games like PUBG Mobile run at more stable frame rates on medium settings
• Multitasking with several apps in memory is smoother
• 5G connectivity uses less power than 4G on the older chip

If you plan to keep the phone for more than two years, the G77’s newer CPU will age better. The G57’s chip is already two generations behind, and Android updates will likely stop earlier.

Display and Refresh Rate: Smoother or Sharper?

Both phones have a 6.6-inch IPS LCD with a 120 Hz refresh rate. That is unusual at this price point and makes scrolling feel fluid on both devices. The difference is in resolution: the G57 Power offers 720p (1600×720), while the G77 Power 5G steps up to 1080p (2400×1080).

The 1080p panel on the G77 is noticeably sharper when reading text or watching videos. At 720p, the G57 shows slightly pixelated edges on small fonts, especially if you hold the phone close. The G77 also gets brighter, reaching about 500 nits peak brightness versus the G57’s 400 nits, making it easier to see outdoors.

Refresh rate alone is not enough to justify a purchase, but combined with the resolution upgrade, the G77’s display is clearly superior. If you stream a lot of video or read articles on your phone, the G77 is worth the extra money.

Battery and Charging: The Power Name

Both phones carry a 6000 mAh battery, which is the defining feature of the Power series. In real-world use, that means about two full days of moderate use – messaging, browsing, and occasional video streaming. Heavy users can expect a full day with 20-30% left at bedtime.

The charging speeds differ slightly: the G57 supports 33 W wired charging, while the G77 supports 30 W. The difference is negligible – both take about 70 minutes to go from 0 to 100%. The G77’s more efficient processor means it may drain slightly slower during the same tasks, but the difference is small.

One important note: neither phone supports wireless charging. If that is a priority, you will need to look at a different series entirely.

Software and Updates: Longevity Matters

Motorola promises two major Android updates and three years of security patches for the G77 Power 5G. The G57 Power gets the same promise, but because it launched earlier, its clock is already ticking. The G57 shipped with Android 14 and will likely stop at Android 16, while the G77 ships with Android 15 and will reach Android 17.

That extra year of updates is significant for security and app compatibility. Banking apps, new Android features, and security fixes for vulnerabilities all depend on timely updates. If you keep phones for three years or more, the G77 is the safer choice.

Camera and Other Specs: Minor Differences

Both phones have a 50 MP main camera with an f/1.8 aperture, a 2 MP macro lens, and an 8 MP front camera. In daylight, photos look nearly identical – sharp, with decent color but slightly oversaturated. At night, both struggle with noise and softness, which is expected at this price.

Video recording is capped at 1080p/30 fps on both. There is no optical image stabilization, so handheld video will be shaky. The G77 has a slightly better image signal processor (ISP) from the newer chip, which helps with HDR and low-light processing, but the difference is subtle.

Other specs worth noting:

• Both have a side-mounted fingerprint sensor that doubles as the power button
• Both have a 3.5 mm headphone jack
• Both have expandable storage via microSD (up to 1 TB)
• The G77 has Wi-Fi 5; the G57 has Wi-Fi 4 (slower on crowded networks)
• Both have NFC for contactless payments (in most regions)

How to Choose: A Practical Guide

Here is a simple decision tree based on your priorities:

1. If you are on a strict budget and only need 4G: The G57 Power is fine. You will save money and still get a huge battery and a 120 Hz screen.
2. If you plan to use the phone for 3+ years: Choose the G77 Power 5G. The newer chip and extra update guarantee make it worth the premium.
3. If you watch a lot of video or read text: Choose the G77 for the sharper 1080p display.
4. If you are a heavy gamer: Choose the G77. The Dimensity 6300 handles sustained loads better and will not throttle as quickly.
5. If you care about resale value: The G77 will hold its value better because of the newer processor and display.

If the price difference is less than 20%, the G77 is almost always the better buy. If the price gap is larger, the G57 still offers excellent value for basic users.

Common Problems and Misconceptions

A frequent misconception is that the G57 Power supports 5G because its name includes “Power” and many budget phones now have 5G. It does not – it is strictly a 4G LTE device. The G77 Power 5G is the one with 5G.

Another issue users report is that the 120 Hz refresh rate on the G57 is not always active. By default, both phones use an “Auto” refresh rate mode that drops to 60 Hz to save battery. To force 120 Hz, you must go to Settings > Display > Refresh rate and select “High.” This is a common complaint that is actually a setting, not a hardware flaw.

Battery drain complaints on the G57 often stem from the 720p display upscaling content – the phone is doing extra work to render 1080p video on a 720p panel. The G77 does not have this issue because its native resolution matches most video content.

Frequently Asked Questions

Which phone has a better battery life?
Both have the same 6000 mAh battery, but the G77 Power 5G’s more efficient processor gives it a slight edge – maybe 5-10% longer screen-on time under identical usage. In everyday terms, both easily last two days.

Is the G57 Power worth buying in 2025?
Yes, if you can find it at a significant discount and do not need 5G. The 720p screen is a drawback, but the battery and 120 Hz refresh rate are still competitive. Just be aware that software updates will stop sooner.

Does the G77 Power 5G support wireless charging?
No. Neither phone supports wireless charging. You will need to use the included wired charger, which fills the battery in about 70 minutes.

Which phone takes better photos?
They are nearly identical. The G77’s newer ISP helps slightly with HDR and low-light, but you would need to zoom into a 100% crop to tell the difference. Neither is good for night photography.

Can I play heavy games like Genshin Impact on these phones?
Both can run it on low settings at 30 fps, but the G77 will maintain a more stable frame rate and run cooler. The G57 may drop frames during intense combat scenes. If gaming is a priority, the G77 is the minimum you should consider.

Which phone has a better display for outdoor use?
The G77 Power 5G. Its 1080p panel is brighter (around 500 nits vs 400 nits) and has better sunlight legibility. The G57 is usable outdoors but you will need to shade it with your hand.
