The official model of this Kindle is Kindle Keyboard, named after its iconic physical full keyboard. It was released in 2010 and is the third generation of the Kindle series, so it is often called Kindle 3 by enthusiasts. The “3G WIFI” you mentioned means that it supports both 3G mobile networks and Wi-Fi.AMAZON KINDLE 3 3G WIFI Kindle Keyboard III BatteryCore InformationBattery Type:
Built-in rechargeable lithium-ion battery. It is not user-replaceable and requires disassembly to be replaced, unlike the earlier Kindle 2nd Generation (replaceable back cover battery).
Battery Capacity:
The official nominal capacity is 1750 mAh.
Battery Life (Official Data):
When wireless connection is turned off (flight mode): Up to one month on a single charge. This is measured under the conditions of reading for half an hour a day and setting the screen brightness to a low (10).
When using wireless: Up to 10 days on a single charge. This is based on reading for half an hour daily, with wireless always on, and downloading books once a week.
When using 3G:AMAZON KINDLE 3 3G WIFI Kindle Keyboard III Batterylife will be significantly shorter than when using Wi-Fi, as the 3G module consumes significantly more power than Wi-Fi.
According to current usage: Given that your Kindle Keyboard is over 10 years old, the actual battery performance will almost certainly be significantly lower than the official figures listed above. This is due to the aging characteristics of all lithium-ion batteries.
Battery Aging: Lithium-ion batteries naturally age over time and with multiple charge cycles, gradually decreasing their maximum capacity. A Kindle 3 that has been used normally for many years may have a battery capacity of only 50%-70% of its original capacity, or even less.
Actual Battery Life: According to feedback from many users who still use the device, an older Kindle Keyboard in airplane mode may only last for one to two weeks of daily reading time, or even less. If you frequently use the light (if your model has one) or connect to the internet, battery life will be reduced.

Use Airplane Mode More Often: Always enable Airplane Mode when you don’t need to download new books or sync. This is the most effective way to conserve battery.
