iHealth Gluco+ IMPORTANT BLOOD SUGAR TESTING!

My brother bought me a iHealth Gluco+ due to the fact that I'm a diabetic and need to test my sugar regularly. However M-kem is not my main problem but the blood sugar machine is( iHealth Gluco+). I charged it as instructed,only lasted a day. Charged it again last night and showed fully charged by 19h30. I was not feeling well by 23:45 and wanted to test my sugar and machine was dead! This is a huge problem for me as a diabetic. It is already on charge again this morning at 07h00. My sugar testing is very important and I can not go without it!
