I recommend a smartphone that is easy to use now, with a large screen and a long standby time.

Samsung i9220 (Galaxy Note) currently has the largest screen in the mobile phone, with a battery of 2500mA, which should be the big brother in the current battery capacity.

There are a lot of smartphones with ultra-long standby time on the market now, and here are some common brands and models:1Nokia 105:

Although not a smartphone, the Nokia 105 can have a standby time of up to 35 days, making it ideal for users who need to go without charging for long periods of time. 2.Samsung Galaxy M51:

It is equipped with a giant 7000mAh battery that can achieve a battery life of up to several days. 3.Huawei Mate 40 Pro:

Equipped with a 4400mAh battery, it supports super fast charging and wireless charging, and the battery life is excellent. 4.Xiaomi Mi 10 Ultra:

With a 4500mAh battery capacity and support for 120W wired fast charging and 50W wireless fast charging, charging can be completed in a very short time. 5. vivo y30：

It is equipped with a 5000mAh battery, which lasts longer than the old mind. 6.Honor V30 Pro:

Equipped with a 4100mAh battery, it supports ultra-pulse-level fast charging and wireless charging, which can achieve long standby time. The above are some common smartphones with long standby time, but it should be noted that the specific situation of using the phone (such as frequency of use, network environment, etc.) will affect the battery life.

Here are some smartphones with ultra-long standby:1 oukitel k10000 pro：

The phone has a built-in 10,000mAh battery that lasts for 7 days. It also has fast charging and can be fully charged in 3 hours. 2.

Blackview P10000 Pro: The phone has a built-in 11,000mAh battery that lasts up to 5 days. It also has dual rear cameras and fast charging.

3.Ulefone Power 5: The phone has a built-in 13,000mAh battery that lasts for 7 days.

It also has dual rear cameras and fast charging. 4. doogee bl12000：

The phone has a built-in 12,000mAh battery that lasts for 4 days. It also has dual rear cameras and fast charging. 5.

Energizer Power Max P18K Pop: The phone has a built-in 18,000mAh battery that lasts for 50 days of standby time. Slam also has a triple rear camera and fast charging.

These ultra-long standby smartphones are equipped with a large-capacity denno chibi pool, so they can be used for a longer period of time after a single charge. However, due to the large loss of battery capacity, the volume and weight will increase accordingly.
