A recent battery technology study by research group RENEW showed the Samsung Galaxy Note7 and LG G6 batteries were the best choice for powering the Galaxy Note8.
This is in line with a recent report from research group PowerTrends which said Samsung and LG were the only manufacturers to make the top 10 battery choices.
The researchers said that Samsung’s battery is “the most durable and energy efficient”, with a claimed energy efficiency rating of 90 per cent.
This was the highest energy efficiency in a wide range of battery technologies.
In terms of battery life, the researchers said Samsung’s batteries lasted an average of 8 hours and 25 minutes and LG’s batteries last an average 11 hours and 20 minutes.
The LG G7 battery was the third best choice with a reported average battery life of 10 hours and 23 minutes.
Other notable findings of the research included the Galaxy S8 battery lasting an average 9 hours and 19 minutes and the Galaxy K7 battery lasting 7 hours and 8 minutes.
There was also a significant gap between the two battery technology’s energy efficiency ratings with the Note7 battery only rated at 92 per cent and LG claiming 95 per cent energy efficiency.
However, this was the worst overall rating, with only the Note8 claiming a worse rating at 83 per cent efficiency.

In the same category were the Samsung A8 and A9 Plus with an efficiency of 85 per 100, and the Samsung C9 and C9 plus with an average efficiency of 76 per cent in the A10, A11 and A12 battery categories.
Samsung also had the most power in the categories of battery capacity, battery life and battery life per hour with a rating of 12.5 per cent each.
The Samsung Galaxy G7, LG J7 and Samsung A10 batteries had the least energy efficiency with an expected energy efficiency rate of 60 per cent per hour and 75 per cent over the 12.1 per cent rated for the battery types.
The RENE-EW battery technology group said it would like to see manufacturers improve the energy efficiency and durability of their battery technologies, particularly in the areas of power and life.
“The best battery technology for powering an iPhone 8, Galaxy S9, Galaxy J8 or Galaxy A10 is Samsung’s S7 edge,” the report said.
“This is despite a battery capacity of just 9.9 per cent.”
This was followed by LG’s A9 with a potential life of 5.3 hours and the J7 with a life of 4.4 hours.
The Galaxy A5, A6 and A7 were the next two best rated, with the life of 8.9 hours and 4.3 per cent life respectively.
“As for the iPhone X, we think that Samsung has a clear lead in terms of energy efficiency but it should be noted that the A8 is rated by the RENews group as having a life rating of 2.8 hours,” the RENE researchers said.
They added that Samsung is also well ahead of LG in terms for battery life with an estimated life of 11.5 hours and 7.9 years respectively.
The latest Samsung phones and the new iPhone X have been reported to have a life expectancy of 12 months with the iPhone 8 plus having a reported life expectancy for an estimated nine years.
“We expect Samsung to continue to make improvements to its battery technology over the next few years, with a focus on improving battery life across all of its products,” the researchers added.
