Regular readers gg surely they know about my attitude to the issue of the autonomy of smartphones, and that there is no thing in the world more annoying for me than the question “how long does the battery hold”? I have already detailed my opinion on this extraordinary topic (and at the same time described why it is extraordinary, as well as what affects the autonomy of smartphones and how to extend it. Therefore, here I will dwell on simple questions that naturally interest everyone who studies the consumer capabilities of Galaxy Z Fold2: How does the fact that it has a huge “tablet” screen affect its ability to work without recharging?
It’s worth starting with the fact that Galaxy Z Fold2 has two batteries, each of which is located in its own part of the case. Despite this, they, of course, work as a whole, and the manufacturer indicates their total capacity at 4500 mAh. As in all other cases, this capacity is sufficient for a smartphone to be considered capable of working without recharging for a whole day. The balance of technical characteristics of a smartphone always consists of multidirectional factors: a productive processor reduces battery life, and modern energy-efficient screens, on the contrary, increase it. A larger screen size is always the way to a higher battery discharge rate, and a higher capacity of the same battery, on the contrary. Etc.
If you look at the weekly chart of battery usage, you can see that on none of the days of the week I completely discharged my smartphone. And on the last day on the graph, it was discharged to 3% of the charge by 8 o’clock in the evening, while at midnight it was not even 100% charged. At the same time, over the past 24 hours, the screen’s operating time was 4 hours, although it would be great, in the case of the Galaxy Z Fold2, to separate the data on the use of both screens, I hope Samsung will add such an opportunity in the future (and it is cloudless for smartphones of the Fold series – this is obvious already now) along with the ability to separately control the settings for each of the displays.
All this, of course, does not mean that the Galaxy Z Fold2’s battery can be drained, if you set such a goal, in 6-8 hours of operation. It is enough to activate the maximum productivity mode, turn on the screen at maximum brightness, launch Fortnite or PUBG, and also turn on the sound to the maximum. For persuasiveness, you can also activate a dozen settings that track various user actions in the background (for example, did you know that Galaxy Z Fold2 can bring up and hide back the notification panel with a swipe of your finger across the fingerprint sensor, if this function is activated?) And also a little bit consume battery power.
A fully charged battery is shown in the settings as capable of working 1 day and 8 hours in the optimized productivity mode. This is the default operating mode, it is perfect for the vast majority of scenarios using a smartphone, so an inexperienced user may never even enter these settings and everything will work at its best. At the same time, noticing a low battery charge, the smartphone itself will offer to switch to power saving mode. Samsung also has great and unique functionality like Bixby scripts, which let you switch between battery life / productivity modes based on the time of day, your location, and other events.
Other modes – maximum productivity and moderate energy saving give a forecast of autonomous work in, respectively, 1 day and 5 hours, and 1 day and 15 hours. The difference between the boundary forecasts is 10 hours, but this is realistic data – the smartphone is unlikely to work for two full days or less than one day, regardless of the power saving mode.
What else you need to know about the Galaxy Z Fold2’s battery capabilities
Galaxy Z Fold2 supports all modern charging types: fast (25 watts), fast wireless (11 watts) and reversible wireless (4.5 watts), when it is capable of wireless charging functions for other devices (usually accessories – smart watches or TWS headphones ). The smartphone is fully charged in about two hours, in the first half hour it gains about a third of its capacity.
In the advanced battery settings (the section is called Monitoring the energy consumption of programs), you can control the automation that allows you to track unused (put them into sleep mode) or rarely used applications (force limit their power consumption). This also improves the battery life of the Galaxy Z Fold2.
Three things to know about the battery life of the Samsung Galaxy Z Fold2
- The Galaxy Z Fold2 has a two-block battery with a total capacity of 4500 mAh.
- The easiest way to control the battery life of a smartphone is from the battery settings menu, choosing the desired mode (the default is optimal).
- In most cases, the battery will last for the whole day.
