In addition, the lithium battery is not suitable for overdischarge, And the overdischarge is also very unfavorable to the lithium battery. This raises the following question.
2. When should I start charging normally?
In our forum, we often see this saying, because the number of charge and discharge times is limited, so we should use up the power of the cell phone battery to charge again. However, I found an experiment table on lithium-ion battery charging and discharging cycles. The following

But I found a test sheet on the charging and discharging cycle of lithium-ion batteries, the data on cycle life are listed as follows: Cycle Life (10%dod): >1000 cycle Life (100%dod):; 200 times one of the DoD is the English abbreviation for the depth of discharge. Can be seen from the table, the number of charges and the depth of discharge, 10%
