Previously, these powerful batteries were used either on flagship devices or for protected ones. Times have changed, and even budget smartphones are now equipped with large-capacity batteries (of course, not all). In this review, we have collected the most interesting devices from the inexpensive segment.
realme C3 3 / 64GB
In this particular case, the most interesting for us is the battery capacity: here it reaches 5000 mAh, however, without fast charging. At the same time, realme C3 has another feature – this is the MediaTek Helio G70 processor. What is it about him? By budgetary standards, it is considered a gaming one: in fact, it shows excellent results in games.
The smartphone received a 6.52-inch display, 3 GB of RAM and 64 GB of main memory, a fingerprint scanner and a triple camera on the back of the case: the main module, portrait and for macro. Shoots usually.
Let’s not forget to note the presence of the NFC module.

Xiaomi Redmi 9A
Xiaomi Redmi 9A is slightly cheaper than Redmi 9C, so it is understandable that its characteristics are simpler. The battery capacity is 5000 mAh.
The case and display of smartphones, apparently, are completely the same, as evidenced by the dimensions. But the camera here is single, there is no fingerprint sensor, as well as the NFC module, and the chip is used completely different – MediaTek Helio G25. The amount of memory is smaller – 2 GB of RAM and 32 GB of ROM.
Verdict? In our opinion, it makes sense to pay a little extra and take a much more interesting Redmi 9C in all respects. That being said, we think the Redmi 9A is an excellent smartphone for its price.
