I was recently using my phone yesterday at 6pmIt was down to the last 5% charge. I plugged it in and could see the lightning (charging). I kept using my phone and it went down to 1%. I know phones dont charge well when you are using them but i needed to do something quick. I left it alone at 1%, but i guess it was a bit to late and it turned off. Normally it would show that its charging and the percent on the screen since it was already plugged in. Nothing showed. I unplugged it and re-plugged it and nothing. I decided to leave it alone. This morning 7am i plugged it again left it for awhile and it was warm bit it still wouldnt turn on. I has only been 6 months that i had this phone. I want to say its the battery but i dont know. Do you have any idea. It was working fine. I have uses the phone until it reaches 1% and it has died but never this
The geek squad was smart in doing a boost charge to the battery. What most people are unaware of is that most lithium ion batteries in phones and other devices actually have a protective circuit enclosed in the battery. This helps prevent damage to the battery due to overcharging, discharging, extreme temperatures, and other factors. If a battery discharges below a certain voltage it can trigger the protective circuit. When it is in this state the battery will read at 0volts with a multimeter. You can wake the battery by doing a boost charge. It’s kind of like jumping a car battery. You are supplying the battery with a higher voltage for a short period of time. By doing this it wakens the battery from this sleep state and then you can use the original charger to finish charging the battery. A lot of people throw away perfectly good lithium ion batteries because they think they are dead when in reality they actually are not and just need boosted to get them to charge and function again. This is especially true for batteries that have sat for awhile unused. To help prolong the life of your batteries try to connect your phone to a charger when it’s between 15-20% and let it charge to at least 90% if possible. I know this is not always possible but it will help extend the batteries lifetime by preventing from overcharging and discharging to often, which can affect the health of a battery. Extreme hot and cold temperatures can also affect the life of your battery.
Hi, @chamis A lot of retailers do not do warranty work unless you purchase (or are given in the deal) a warranty agreement from them but there is always the manufacturer’s warranty on the product. In most cases it is for 1 year (12 months) and as you have a new model phone you should still be covered. Verify this by checking the purchase receipt for the phone. If the phone is still within the warranty period consult the warranty information contained in the documentation that came with the phone as to what you have to do to make a claim for a manufacturer’s warranty repair or replacement. If you cannot find the documentation, go online and search for Samsung galaxy A9 (2016) warranty for your location.
