Battery life is one of the biggest concerns for any smartphone buyer out there and more so for the ones who travel a lot. There is no replacement for a good battery life out of a handset no matter how prepared a person is with the power banks and all.
This aspect of owning a smartphone doesn’t have any alternatives – consider this – if you have a flagship-grade phone then you want a good battery life because you want to enjoy all the good stuff uninterrupted. And if you have anything cheaper, then also you want a good battery life because any device which is not high-end already compromises on other aspects of performance, camera quality and the overall performance. The battery life is a paramount requirement.
And so, we are bringing you the battery comparison of three lower mid-range devices, namely – Redmi 5 Plus, Honor 7X and Xiaomi Mi A1. The usual suspects in this trio are the Honor 7X and the Xiaomi Mi A1 while the Redmi 5 Plus is mostly going to be launched in the coming February 14. However, we have previously compared the three devices for their camera prowess as well as their gaming and performance capabilities.
We are expecting the Redmi 5 Plus to be priced lower than the Xiaomi Mi A1 (Rs 13,999 starting price) and the Honor 7X (12,999 starting price).
Let’s see how much battery each of these smartphones carry in order to have an idea of what to expect out of them:
REDMI 5 PLUS
Display: IPS LCD 5.99 inches, 1080p x 2160p resolution (Full HD+), 403 ppi
Processor: Qualcomm Snapdragon 625, Adreno 506
Display: IPS LCD 5.99 inches, 1080p x 2160p resolution (Full HD+), 407 ppi
Processor: HiSilicon Kirin 659, Mali-T830 MP2
XIAOMI MI A1
Display: LTPS IPS LCD 5.5 inches, 1080p x 1920p resolution (Full HD), 403 ppi
Processor: Qualcomm Snapdragon 625, Adreno 506
BATTERY by the NUMBERS
By the numbers, it would be hard to argue against the Redmi 5 Plus which comes with a generous 4,000mAh battery. The Honor 7X with the 3,340mAh unit is at 2nd while the Xiaomi Mi A1 has the least powerful battery at 3,080mAh going purely by the spec sheet. Do the phones finish in the same order as their respective battery ratings suggest?
Not entirely, as we found out. The Honor 7X went out of juice quicker than both the other devices in various scenarios even when it is not the one with the smallest battery. When putting all three handsets through specific tasks for 30 minutes each, we found out that the Honor 7X consumed most amount of juice out of its 3,340mAh battery. The Xiaomi Mi A1, on the other hand, performed better than the 7X. Lastly, the Redmi 5 Plus consumed the least amount of battery in each activity.
Let’s take a look the numbers consumed.
Redmi 5 Plus
Gaming – 8% consumption
Video Recording – 8% consumption
Video Playback – 4% consumption
Songs – 2% consumption
Gaming – 14% consumption
Video Recording – 13% consumption
Video Playback – 8% consumption
Songs – 6% consumption
Xiaomi Mi A1
Gaming – 12% consumption
Video Recording – 11% consumption
Video Playback – 6% consumption
Songs – 5% consumption
From the numbers above, it is clear that the Honor 7X is the hungriest smartphone in this trio followed by the Xiaomi Mi A1 and the Redmi 5 Plus. This behaviour continues in the normal usage as well which means performing regular day-to-day tasks without much heavy usage while including the standby time as well (the preferable situation for this is when the phone is unused at night when we sleep).
BATTERY CONSUMPTION under NORMAL USAGE and the CHARGING TIME
All three phones have a Full HD display and almost the same screen size (the Mi A1 being around half inch smaller at 5.5 inches compared to the 5.9 inches of the Honor 7X and the Redmi 5 Plus). Also, the Redmi 5 Plus and the Mi A1 have the exact same Snapdragon 625 processor (which comes bundled with the Adreno 506 GPU) and the 4GB RAM (this is same across all three devices).
When it comes to charging, none of the three phones get fast charging and the adapter rating for all three phones is at 5V-2A. The difference between the charging times between the three handsets is fairly small. However, the Honor 7X took the longest to get charged from 0% to 100% with 2 hours and 30 minutes flat. The Redmi 5 Plus took 10 minutes less to arrive at 100% with 2 hours and 20 minutes and the Xiaomi Mi A1 took about the same time as well.
Under normal usage which includes making a few small calls, sending messages, listening to some music, spending time over the internet (including social media) and making a light use of the camera (while avoiding the video recording completely), the Redmi 5 Plus and the Xiaomi Mi A1 would advance to the second day with more life left in them compared to the Honor 7X. Especially the Redmi 5 Plus would go on till 1 and a half days before you would be pushed to connect it to its charger. In comparison, the Xiaomi Mi A1 would last around a couple of hours less while the Honor 7X will have to be connected to its charger by the end of the day.
Please understand that the battery life for any handset will vary from person to person depending on the usage. However, we can confidently say that the Redmi 5 Plus upholds its largest battery rating in this group of handsets and lasts longest while the Xiaomi Mi A1, with the smallest battery, trumps the Honor 7X for the 2nd spot.
WHY DOES THE XIAOMI MI A1 LASTS LONGER THAN THE HONOR 7X?
So, the Redmi 5 Pus has the best battery backup in this trio of lower mid-range devices. But why does the Xiaomi Mi A1 goes on longer than the Honor 7X even with the smallest battery?
The reason seems to be the more efficient battery management by the Snapdragon processor. The Snapdragon processors usually have a better reputation in battery management compared to their Kirin counterparts especially when we are talking about the Snapdragon 625 and higher. Also, the Mi A1 gets the pure Android software thanks to Google’s Android One program. In comparison, the HiSilicon Kirin processor appears to be more power hungry and the MIUI custom user interface, although quite light, is not as light as the pure Android.
This comparison is a proof that having a big battery does not always translate to longer battery life, not for all handsets. There are other factors like the processor and the software that are involved in determining how long a handset will run in a single charge. Lastly, not to forget an individual’s usage style.
BUT THE WINNER IS….
This is the reason the Redmi 5 Plus runs the longest – it gets the Snapdragon processor combined with the massive 4,000mAh battery and in this case at least, the numbers on the battery do their job very well.
