A Complete Analysis of Nokia 105 Battery Life: How to Revive a Classic Phone for Older People?

Fully charged, leaving the house, only to have it shut down by the afternoon—this isn't just a smartphone problem; your Nokia 105 could be facing a battery crisis, too.

In the feature phone market, the Nokia 105, with its ruggedness and affordability, has become a top choice for many users as a backup phone or for older people. However, even this classic model, renowned for its long battery life, can experience battery degradation over time.

If you find that your Nokia 105, which once required weekly charging, now requires frequent recharging, or the battery indicator suddenly jumps, or even shuts down for no apparent reason—it's not a sign it's time to retire; it's simply an old battery.

As a feature phone, one of the Nokia 105's greatest strengths is its long battery life. Official data indicates that the Nokia 105 2025 model, equipped with a 1000mAh removable battery, offers up to 12 hours of talk time and 22 days of standby time.

However, the chemical properties of lithium batteries make them one of the shortest-lived components in a phone. HMD's official guide clearly states: "The battery can be charged and discharged hundreds of times but will eventually fail. Replace the battery when the device's standby and talk times are significantly shorter than normal."

Temperature is a key factor affecting battery life. For optimal performance, the battery should always be kept between 15°C and 25°C (59°F and 77°F). Extremely high or low temperatures reduce battery capacity and lifespan. In cold conditions, the battery can drain quickly, shutting down within minutes due to low charge.

Actual user experience has been less than ideal. Several users have reported: "Battery life...it seems that 4G connectivity and the new SoC chip are not easy on the battery, even when in standby or not making HD/VoLTE calls." This results in even the newly purchased Nokia 105 4G version struggling to live up to the expected battery life.

Battery specifications vary by model.

Nokia 105s released in different years have different battery configurations:

Nokia 105 2025 model: Equipped with a 1000mAh removable lithium-ion battery

Nokia 105 4G version: Battery capacity increased to 1450mAh

Nokia 105 Dual Sim 2023: Also uses a 1000mAh removable battery

User feedback on actual battery life

Despite the official standby time rating of up to 22 days, actual user experiences vary widely. One user complained, "Terrible battery life... This phone is so annoying." Another noted, "The new 105/110 4G (2023) upgrades the battery size to 1450mAh (same as other 4G feature phones using the same chip) which may mean this is necessary," suggesting that the earlier versions had insufficient battery capacity.
