Product Information

Bigger batteries obviously provide more power to play with, but manufacturers’ underlying hardware choices have just as big of an impact on actual battery life results.

However, this is seldom the case, as internal hardware and therefore power consumption varies so widely.

You can also reduce the battery life of your portable charger, which also reduces how long you can use it to supply juice to your smartphone. So you’ll need a roughly 20% larger battery capacity to achieve the same battery life as an equivalent 4G phone.

That said, we don’t recommend going under 5,000mAh in most cases and think 10,000mAh is the sweet spot for portability. Batteries are an important part of keeping many gadgets running smoothly and making life easier for everyone. The 2,800mAh Google Pixel 4, 4,000mAh Galaxy S20 (Exynos model), and the 4,510mAh OnePlus 8 Pro all fall within just a few minutes of each other. Avoid charging your power bank and smartphone at the same time – Charging your smartphone while charging your power bank can put a strain on the battery capacity of the latter device. I am often found in my shed refurbishing batteries for friends and family or repairing anything with moving parts that run off a battery.

Manufacturers can also under or overclock chipsets and even alter the CPU scheduler to hit their preferred performance and power points. The Google Pixel 4 and its Soli radar system is a prime example of a feature that drains much more battery than a handset without it. Most power banks are made from lithium, and lithium-ion batteries have been known to degrade over time.However, whether this is a crucial purchasing consideration depends on whether you’re actually on a 5G or 4G network. Including a time-of-flight camera focusing system, more powerful stereo speakers, or a 4K display all impact battery life. Actual charging speed may also vary depending on the actual usage, charging conditions and other factors. Again though, these SoCs have slower peak speeds, so it’s another power versus performance trade-off.
