Battery and Charging

Let’s examine the battery performance between models next…

Battery Size & Life

  • Moto G Fast: 4,000 mAh (Up to 2 days)
  • Moto G 5G: 5,000 mAh (Up to 2 days)

Motorola is well-known for excellent battery life, and both these models deliver on that promise. However, the upgraded Moto G 5G does manage to squeeze in a larger 5,000 mAh cell versus the 4,000 mAh battery found in the Moto G Fast.

In real-world usage scenarios, most buyers should expect about 1.5-2 days of runtime on a full charge from either device when using it moderately. But when push comes to shove, the G 5G can stream and surf longer off each charge thanks to that higher capacity rating.

Charging Speed

  • Moto G Fast: 10W charging
  • Moto G 5G: 20W TurboPower charging

Despite the similar expected battery life, charging performance does vary wildly different between these two. The Moto G 5G supports blazing-fast 20W TurboPower charging, while the Moto G Fast maxes outs at just 10W.

In practical use, this means the Moto G 5G can juice back up to 50% in about 30 minutes. The Moto G Fast will take nearly double that time to reach half capacity again.

Final Verdict

The battery and charging differences come down to capacity versus charging times. In essence, the batteries last about the same on both models, but the Moto G 5G charges staggeringly fast thanks to its TurboPower support.

For buyers who don’t regularly rapid charge throughout the day, the minor bump in battery size likely won’t impact real-world experience much either. But the option for crazy-fast charging certainly creates far more flexibility in keeping the Moto G 5G powered on when needed most.

Storage and Memory

Now onto internal storage capacity and memory performance…


  • Moto G Fast: 32GB
  • Moto G 5G: 128GB

Once again, the spec sheets showcase a massive divide between these two models when it comes to onboard storage. The Moto G Fast comes with a rather limited 32GB storage drive, while the Moto G 5G offers a whopping 128GB right off the bat.

Power users who install a lot of apps, download media content or capture photos/video will need expansion with the Moto G Fast very quickly. However, the Moto G 5G provides ample room for even robust use cases without reaching capacity limits for quite some time.

Fortunately, both devices do allow for microSD card expansion though. So savvy owners can augment storage somewhat cost-effectively if absolutely needed.

Moto G Fast maximum capacity: 1TB
Moto G 5G maximum capacity: 512GB


  • Moto G Fast: 3GB RAM
  • Moto G 5G: 6GB RAM

Similarly, we see the Moto G 5G’s superiority continue in memory, with 50% more RAM allocated over its cheaper sibling. 6GB allows for excellent multi-tasking capabilities and smooth operations when jumping between multiple apps.

However, budget-focused buyers may scoff at the need for that much memory on a smartphone. The pared back 3GB RAM on the Moto G Fast still completes most common tasks without noticeable slowdowns for the majority of buyers.

Unless you’re a hardcore mobile gamer or constantly flipping between a ton of open apps, the differences in memory likely won’t impact real-world use that substantially. But technically speaking, the extra RAM does provide more breathing room for demanding software.

Final Verdict

The storage and memory upgrades on the Moto G 5G make complete sense given its premium price point. With over 4x more onboard capacity and 50% extra RAM, its a far more future-proof purchase for saturating owners.

That said, casual users who don’t install many apps or house giant media collections can certainly still get by with the Moto G Fast. Just don’t expect blazing speeds when pushing the phone’s limits if opting for lower memory and storage specs to save money upfront.

Performance & Connectivity

Now let’s examine the processing capabilities and connectivity options between the Moto G Fast and Moto G 5G…

Chipset & CPU

  • Moto G Fast: Qualcomm Snapdragon 665, 2.0GHz octa-core
  • Moto G 5G: Qualcomm Snapdragon 750G, 2.2GHz octa-core

The Moto G 5G once again leads in processing power, boasting the superior second-generation Snapdragon 750G over the entry-level 600-series chip inside its sibling.

With its cutting-edge 7nm architecture and faster clock speeds, the 750G outperforms virtually every metric when benchmarked head-to-head. That means noticeably better response times when launching apps, juggling multiple tasks and playing intensive 3D games.

Both chipsets technically offer “octa-core” CPUs though, meaning eight physical cores for improved efficiency across workloads. But the speed and bandwidth advantages of the 750G will be extremely noticeable for power users coming from older devices.


  • Moto G Fast: 4G LTE
  • Moto G 5G: 5G Sub-6Hz

Lastly, in the connectivity department, only the aptly named Moto G 5G supports next-generation wireless networks for dramatically faster data throughput speeds.

5G connectivity unlocks staggering improvements over 4G LTE across both download and upload performance metrics. We’re talking 10-100x speed improvements under the best conditions.

Of course, 5G networks remain sparsely available globally as infrastructure continues growing each month. So don’t expect blazing speeds in most suburb or rural regions quite yet. But investing in a 5G-capable device futureproofs yourself well for the next 3-5 years as availability expands.

And even when not connected to 5G networks, the Moto G 5G still outclasses its sibling with better 4G/LTE bandwidth via carrier aggregation technologies on the 750G chipset.

Final Verdict

The boosted processor and 5G connectivity provides two more feathers in the Moto G 5G’s cap compared to the Fast model. Both deliver smooth all-around performance for most buyers, but media junkies, multitaskers and mobile gamers will squeezing every last bit of power from the upgraded chipset.
