The battery life of an electronic gadget depends on the capacity of the rechargeable element. Cell phones communicate with subscribers via a radio signal, so they do not require a landline connection to function.
The mobility of such devices is ensured by a built-in battery. Smartphones, in addition to their main purpose, can also be used to run various applications, many of which place a heavy load on the processor and built-in memory, causing significant energy consumption.
Apple's iPhone 7 and 7 Plus phones are especially good at consuming power, so before purchasing such a device, you should understand the capacity of the batteries installed on devices of this type.
Characteristics and description of batteries for iPhone 7 and 7 Plus
Knowledge of the basic technical characteristics of the iPhone battery will allow you to monitor the performance of the current source, and, if necessary, replace it with an original product or its equivalent. The iPhone 7 cell phone battery parameters are as follows:
| Characteristic | iPhone 7 | iPhone 7+ |
| Capacity | 1960 mAh | 2900 mAh |
| Voltage | 3.8 V | 3.8 V |
| Length | 93 mm | n/a |
| Width | 39 mm | n/a |
| Thickness | 3 mm | n/a |
| Weight | 30 gr | 100 gr |
The battery installed on the 7 plus model has slightly larger dimensions. The capacity indicators of the battery installed on the improved version of the smartphone are almost one and a half times higher than the standard “seven”.
What is the iPhone battery capacity in mAh
Battery capacity and battery life are one of the main characteristics of any smartphone.
After all, buying a smartphone with a weak battery will definitely become a big headache for the user. Such a device will discharge at the most inopportune moment and create a lot of inconvenience. Therefore, when choosing a new model, users always pay a lot of attention to the battery. Article on the topic: How long does it take to charge a new iPhone 7?
Unfortunately, some manufacturers don't really like to talk about the battery capacity of their smartphones. For example, Apple's website usually lists battery life in hours, but there is no information about the specific battery capacity. In this article you can find out what the battery capacity is in all iPhone models and what operating time they can provide.
Maximum declared capacity for iPhone 7 and 7 Plus
The most important parameter of the new iPhone is the value of the declared maximum capacity. For iPhone 7 smartphones, this figure is about 2 A/h. The iPhone 7 Plus model is equipped with batteries with a maximum capacity of about 3 A/h.
An improved phone model consumes more electricity. Despite the fact that the processors on both models are installed with the same power, the screen diagonal of the iPhone 7 plus is almost 0.8 inches larger, and the number of pixels is higher.
For this reason, the operation of the display causes increased power consumption, which forced the developers to significantly increase the capacitive parameters of the battery for the iPhone 7 Plus.
Changes
This is what the “seven” battery looks like under the housing cover. By the way, it now opens like a book.
The battery of the new iPhone has become a little thinner and longer. It was possible to partially increase its dimensions due to the standard audio jack removed from the module body. Now the capacities are 1960 mAh for the basic version, and 2900 mAh for the “plus” version.
Although this was not a panacea. A powerful processor with updated iOS, and a powerful camera with a super-bright screen simply “eat up” all the reserves received.
But not everything is so sad.
After all, the engineers made their main bet not on increasing the battery size, but on maximizing the operation of the operating system and hardware components of the smartphone. Everything has been done to minimize “idle” energy consumption when performing low-priority tasks.
With an increase in the overall performance of the chip to 50% compared to its predecessor, the “seven” battery not only copes with increased loads, but also shows an increase in battery life hours, albeit insignificant. The company has assigned a major role in reducing costs to the new highly efficient processor. It consists of two clusters, in each of which the designers installed two cores.
One cluster is designed for fast and energy-intensive calculations. It is used only when there is really a need for it - when working with detailed maps, “volumetric” games, graphic editors, etc.
In all other cases, a second, energy-efficient cluster is activated, which ensures the operation of all regular processes. At the same time, it consumes only a fifth of the energy that would be used by the first, productive group of cores.
To redistribute tasks and loads between the cores, the “sevens” have a special controller. It is he who determines the priority of processes and ensures optimal interaction between groups of cores.
All this allows for a significant reduction in energy costs for system operation. As a result, despite the increased costs of new modern units, the “sevens” showed an overall increase in battery life.
During the presentation, it was stated that both types of “sevens” received an increase in battery life. So the 7 Plus will now last a full two hours longer. The survivability of the basic 4.7-inch version is much more modest - the increase was only one hour. But on the other hand, his screen is much smaller, and it is logical that his energy “appetites” are not so great.
Although the absolute increase (relative to its predecessors), in milliamp-hours, is only 245 and 150, respectively. In percentage terms, this is 12.5% for the basic version, and 5% for the 7 Plus.
It is clear that all these laboratory test results come with the caveat that each user's iPhone performance results may differ significantly. After all, we all use our gadgets differently, move differently, and therefore spend energy on conversations, the Internet, searching for a cell signal, etc. – a priori cannot be the same.
And Apple, as always, is playing it safe by slightly underestimating laboratory indicators so as not to once again provoke criticism from skeptical experts.
How to find out the actual capacity
During operation, the ability to accumulate a certain amount of electricity in lithium batteries sharply decreases after 1000 charge-discharge cycles. If your phone is draining quickly, the most likely reason is that the battery is nearing the end of its life.
It is almost impossible to find out the capacity from the display of the phone itself, because such a program only displays the value of the battery charge level. That is, if the battery can no longer accumulate even half of the declared amount of electricity, then even if you look at the charge indicator, it will still show 100%.
You can set the approximate value of the battery capacity as follows:
- Select a fixed power electrical load operating at a voltage of 3.5 - 3.8 volts.
- Fully charge your iPhone battery.
- Connect the load and turn on the timer.
By determining the load in the electrical circuit and the time during which the effective discharge was carried out, you can find out the value of the capacitance. To do this, you need to divide the time in hours by the current in amperes.
What did users expect?
Rumors that the battery life of the seventh iPhones would be longer circulated long before the “seven” went on sale. But then we were talking about 1735 and 2810 mAh, that is, an increase in capacity by 1 and 2%. At the same time, it was mentioned that the service life from charge to charge would be increased using the latest energy consumption algorithms. It was added to this that the new smartphones will have a processor that consumes much less resources. Photos periodically appeared on the network where one could see a supposedly new battery, but even from these photos one could understand that one should not expect a special increase in the battery capacity of the iPhone 7.
Claimed operating time for iPhone 7 and 7 plus
The declared operating time of the improved version of the mobile device, under various modes of use, will be:
- Waiting time – 380 hours.
- Listening to music – 60 hours.
- Conversation – 18 hours.
- Web surfing – 13.5 hours.
- Video viewing – 7 hours.
The amount of accumulated electricity that can be generated by a standard model is significantly lower, and therefore the operational capabilities are more modest:
- Waiting time – 240 hours.
- Listening to music – 40 hours.
- Conversation – 14 hours.
- Web surfing – 10 hours.
- Video viewing – 5 hours.
The listed characteristics are reliable only for new devices. With prolonged use, the operating time in any of the listed modes can drop to almost zero.

Is it possible to increase the capacity of the phone
If the capacity of iPhones is guaranteed to decrease during operation, then it is almost impossible to increase this indicator. The manufacturer has developed and installed a battery in the device that has the longest possible operating time.
This limitation is due, first of all, to the size of the gadget and the compartment where the battery is installed. If the phone's operating time has decreased, then the only option to restore the gadget's performance to its previous level is to purchase and install a new battery.
How can you restore capacity?
If the capacity drops inexorably, it is not recommended to take any action to restore the battery. Using practices recommended on the Internet for restoring lithium-ion batteries can lead to failure of not only the battery, but also the failure of an expensive gadget.
If it is possible to check the actual capacity of the battery, then this must be done. If significant deviations are detected, you should purchase and install an original battery for iPhone 7 or 7 plus.
To preserve battery life for as long as possible, it is recommended, if possible, to refrain from frequently recharging your smartphone. Despite the absence of a memory effect, such operation of the battery is not correct and always leads to premature failure of the battery.

Recommendations
Once again, Apple has presented a non-separable case, from which it is quite difficult to remove the battery without breaking its integrity. In addition, this year water and dust protection added additional problems - it is unknown how replacing the battery pack will affect the seal. Therefore, it would be a good idea to take note of a few simple tips to maintain your performance at peak performance for as long as possible.
In general, the battery of modern gadgets is designed for 1.5-2 years of intensive work. We are sure that almost all users use their iPhones this way – i.e. recharging occurs every day.
Many are accustomed to leaving the device to charge all night, but this should not be done. Driving it to 100% and hanging on the wire for a long time reduces the number of remaining charging cycles several times. And each time the battery capacity will degrade more and more.
Experts advise not to complete charging (as well as to completely discharge the device). The optimal mode is to maintain energy at 40-80%.
You can recharge your iPhone several times during the day, but, again, not bringing it to 100%. A complete discharge can be performed about once a month so that the system can calibrate the “energy meter” and provide the correct level of remaining charge. This will at least double the number of cycles.
Many users complained that recharging the 7 Plus's capacious battery with the included charger takes too long - almost six hours. Not everyone wants to wait that long, and it’s not always possible. Therefore, to speed up the process, you can purchase more than 10 W, it will speed up the process three times. It will cost up to 2 thousand rubles.
You also need to remember one important point that arises due to the water resistance of the “sevens”. To avoid problems with the battery and connector, do not charge the iPhone immediately after it has come into contact with liquids, otherwise the port may short out. Blot the lightning , let it dry completely, and only then connect it to the network.
Remember, if you break this rule, no one will repair or replace your gadget under warranty. This is clearly stated on the company website! In addition, this is a matter of your own safety - due to a short circuit, the charging module may explode.
It is equally important to observe the temperature regime when storing and operating iPhones. So the most optimal temperature is 15-25 °C. Under such conditions, the irreversible annual drop in capacity will be significantly reduced and will amount to no more than 20%. At too high (more than 45 °C), as well as at low (below -20 °C) temperatures, battery degradation will occur much more rapidly - from 35% per year.
