Why is my tablet charging so much less?
You are sure, because the battery, but there is longevity, charging more, then use more times, so it is normal
It's better to ask after sale to see if the battery is out of order or if there is something wrong with your system.
Your battery is running down. Battery loss means that the battery is smaller than the nominal capacity after a long period of use.There are many reasons for battery loss, mainly including:1, the battery itself is poor quality2, use inferior charger3 、 high temperature or low temperature environment for long time operation4, the use of batteries is connected to high load peripherals, plug and play is not standardized.5. Excessive charge and discharge (battery usage is below 3%). Circuits are now protected, but occasionally.6, incomplete charge and discharge (do not use up again, charge, but want to use, use, want to charge as soon as possible)7. Use batteries for long periods of electromagnetic radiation (which interferes with the electrical conductivity of metals in batteries)8. Long term use of batteries under wet conditions (wet cells will decrease in performance)
