When you are hitting 20 % battery permanently on your galaxy, iPhone or Pixel phone, don’t you hate it? Every day is a day of battery anxiety. How much time do we need to bear it?
It is disappointing to say the least, and it seems that the big three are not working much to solve this problem. But there may be a change on the horizon.
The state of smartphone batteries in 2025
Let’s quickly offer flagship batteries and the most famous phones of battery life in 2025. Launching the Galaxy S25 Ultra, we have the exact capacity of 5,000 MAH that we are talking about, and this phone is at the number #23 in our battery benchmark with a comprehensive 8 -hour comprehensive score. Not bad? May be. After that we have archetypes – the iPhone 16 Pro Max manages to improve the S25 ultra with an overall score of 8:30 hours, with a 4685 mAh cell on the board. This result gives the iPhone 14th (for now) on our list.
Finally, the third model that is very popular in the United States – Pixel 9 Pro XL – comes with a battery of 5,060 mAh and the same battery test has a total of 7:18 hours. This results it in #51, which is not very good.
To put in this context, let’s take a look at some other smartphones, including 6,000 MAh batteries or more and how they worked in our tests.
Vivo’s latest two flagship models – Vivo X200 Ultra and X200 Pro – Both contain 6,000 MAH batteries, and they secure our list of #3 and #6, respectively. And if we remove the Midrej Sony Xperia 10 IV from equality, as well as the 2 -year -old Asos Zenfone 10 (which is on the way out of the standard of “our” tested in the last 2 years “, this position is #1 and #4.
In the upper part we also get the Red Magic 10 SS Pro and Nobia Z 70 ultra with its 7,050 mA battery, which has 6,150 mAh seals on the board.
Competition from china

The main reason behind the situation is called silicon carbon batteries. We have a dedicated article to describe silicon carbon technology, but the long story short, it is the process of producing a silicon in a battery graphine anode, which enhances overall capacity.
The thing is, this technology is currently specialized for China and Chinese phones, such as Honor, OnePlus, Noorbia, Vivo, Oppo, and Red Magic devices.
There are about a dozen silicon carbon anode manufacturers in China, and this increase in battery tech has come from the fact that in the last two years, power vehicles in China have also increased the most. And they certainly use batteries.
Therefore, your next phone can have 6,000 MAh battery, especially if it comes from China. Companies like Samsung and Apple are still playing catches, though there are rumors that the two are considering ways to employ this silicon carbon tech in their next flagship model.
Why is 5,000 MAH now not enough?
We all know that is better (or more, as he used to say, as Winnie Poh), but why does it look like 5,000 MAHs don’t cut it? Are our phones hungry from different, more power? And in what ways?
Large and bright screens
Through the summer sun looks like 3,000 nets
Nowadays, smartphones are 90 % of the screen, and these screens are getting bigger and bright every year. We are moving the 7 -inch limit on the largest flagship phone, and even twenty models have increased in size.
The size is not the only culprit for increasing energy consumption. In fact, high and high brightness data that are thrown with each new generation play the most important role in battery drainage.
It is nice to enjoy 5000 nets peak brightness on a screen, but maintaining it for a long time will eliminate your smartphone battery really. Add it to a high display refresh rate, which is a new thing in smartphones, and you will have a picture.
The hungry chip seats from lightning
During each smartphone generation, launch presentations, we get slides with increasing hardware performance. Whether it’s 20 % or more, it has the benefit of power consumption.
Given, the silicon becomes more efficient, but the difference between the generations still exists. Just take a look at the TDP (thermal design power) data for late Snapdragon processors, and you will see the difference.
This TDP number mainly shows how much heat the electronic ingredient produces, and it is closely tied to its performance and energy consumption. For example, Snapdragon 8 Elite has 8.2W’s TDP, while the first generation, Snapdragon 8 General 1, KTDP is 5.3 W.
This is quite a difference, especially if you want to play heavy games or use apps that require serious computational strength.
Extremely apps and beautiful ui
Liquid glass – beautiful, but also hungry from lightning
In the context of the announcement of iOS 26, we may not only fail to mention the user’s interface as an element of power consumption. All dynamic images, transparency, transparency and dynamic design elements require computational power from your smartphone’s GPU (graphics processing unit). This power drainage may not be as severe as it occurs during gaming, but don’t forget that you use your phone’s UI all the time, so the use of energy is heated.
And talking about computational power, guess what of it is needed? Appearance
AI features
We know that many heavy AI works are done by the server, but companies try to transfer more AI features. It is also worth the security purposes and that your phone is doing AI magic.
All this requires special silicon, nerve network hardware chips that are an additional power user.
Once again, when using a direct translation, your battery does not immediately look at the percentage indicator, for example, but all these things increase.
Conclusion
Silicon Carbon Technology can come to Samsung and Apple Phone
So, is there a solution? Should we go for midwife charses and small refresh rate small phones? No, not at all! We are on a transition in 2025, looking forward to adopting silicon carbon battery tech of large companies.
We must hold our horses and wait for this if we want to stick to iPhones and galaxies. Or if we want to hop on this train soon, we can always choose a flagship with a silicon carbon battery.
The honor is deep within the fourth generation of the tech, and brands like One Plus and Xiaomi are also riding. The future is bright, and despite still hungry chip sets and display, we can eventually have two or even three days of battery life on our dear smartphones.
