🔋 1. Battery Upgrade: The Biggest Change
The important thing about the new Galaxy Z Fold 8 is that it has a bigger battery.
📊 Standard Galaxy Z Fold 8
The new Galaxy Z Fold 8 is expected to have a battery that’s around 5,000mAh. The old model, the Z Fold 7 had a battery that was 4,400mAh. So the new one is 13% bigger.
👉 This means the Galaxy Z Fold 8 will have the battery that has ever been used in a Galaxy Z Fold phone.
📊 Galaxy Z Fold 8 ” Fold” Variant
The wider version of the Galaxy Z Fold 8 is expected to have a battery that is around 4,800mAh. This is what Samsung is saying. The actual battery capacity might be a little lower around 4,660mAh. It is still bigger than the battery in the Fold 7.
⚙️ Dual-Battery Setup
Samsung is still using a system where there are two batteries, one in each half of the phone. These two batteries work together like one battery.
For example if each battery is around 2,369mAh then together they would be around 5,000mAh.
👉 This design helps keep the phone slim and makes sure that the heat is spread out evenly. It also helps the phone stay balanced when it is folded.
📉 2. Why This Upgrade Matters
The problem with the Galaxy Z Fold models was that they had small batteries. Samsung used the 4,400mAh battery in the Z Fold 3 Z Fold 4 Z Fold 5 Z Fold 6 and Z Fold 7. Users were not happy with this because the battery life was not good.
People who used their phones a lot for things like gaming and watching videos would run out of battery quickly.
👉 Even though Samsung tried to make the battery longer it was still a problem.
The new Galaxy Z Fold 8 is supposed to have a battery, around 5,000mAh. This means that the phone will last longer and people can use it more without needing to charge it.
