Solution

Use the following steps to extend the device's battery life:

Battery standby time is short

1. The standby time mentioned in the User Manual is only for reference. This time is measured in a laboratory environment where: the device’s battery is fully recharged, a SIM card is installed, and network signal strength is standard. The battery life is consumed by installing a SIM card, making calls, using the internet, sending text messages, and using the device. This causes standby time to vary and be different from the time mentioned in the User Manual. This is normal.

2. Battery performance or main unit power consumption may also lead to short standby time. In such cases, we recommend you take the device to the nearest repair service site for professional inspection and handling.

Suggestions for improving battery performance:

1. When you first start using your new device, the new battery is not fully charged. Plug the battery adapter into the tablet and a wall socket. It might take a few seconds for the battery to start charging. Allow the battery to charge until it reaches 100%.

2. If the battery is fully discharged, it might take several minutes for the device to commence charging. The battery has to charge to a minimum voltage before the system can start up, and this could take a short while to accomplish.

3. It is best to use the Lenovo charger that comes with the tablet. Chargers have different output capacities, and a weak charger will take longer to charge the battery. If the device is in heavy use, it may be possible for a weak charger to fail to provide enough energy to actually charge at all.

4. During initial set up of the device, once you have added accounts (such as Google) the device will typically transfer significant data while it initially synchronizes your accounts and updates applications from the Play Store. The tablet's battery may drain faster than usual during this initial session. After the initial sync, and a few charging cycles, the battery will reach its maximum capacity. We recommend keeping the tablet attached to the charger during the initial sync.

5. It may take several charging cycles for the battery to reach optimum performance.

6. During the charging process of your device, it is recommended that you avoid using it at the same time, as this may potentially lead to higher power consumption.
