My iPhone battery is acting weird. What should I do?

.Okay so my battery can be a bit jumpy. I have an iPhone 7 Plus and it's not a bad phone. However, it's been a tiny bit glitchy so when I go to restart it, the battery would jump. For example if I were to restart it and the battery is at 50%, and the phone restarted the battery would be at 55% and quickly go down. But, if I were to restart it on the charger and the battery was sat 100%, it would be at 97% and sometimes it would go down but when I put the charger back in the phone it would go back up at 100%. Is this to be of any concern or is it fine?

How do I find out if my adopted sister is Donald Trump's biological daughter?

So I've seen my sister's birth records and her father was African-American and her mother a white teen of German ancestry. My sister is narcissistic, loves throwing out insults, rowdy, and comes across as a white girl in physical appearance.

My sister has no desire to do the DNA test or contact the birth family despite us knowing the birth mothers name. My parents even met the birth mother and her mother. My sister does not like African-American like the guy who's claim to be her father who my parents have a picture of. He was a teenager just like the birth mother.

So what my question is is this, how can I convince my sister to give me a DNA test so I can find out if she has Donald Trump's daughter? My sister looks too white to be the daughter of the guy photo does the birth father but she's very narcissistic like our president.

Please excuse any spelling errors as I'm talking into my iPhone.

Is it safe to use my laptop?

My compaq laptop fan has been making loud whirling sounds I think the fan might need to be either cleaned or replace which probably won't happen for a while because I may never have the time to do it or find someone to do it. I've had it for 13 or 14 years it's working well but the fan is making me nervous. The other day I was using it to sync iTunes music the fan was really loud I was nervous it would either blow up or ruin my iPod. I got 3 laptops it's the only one I can get iTunes because the others are Chromebook which I can't get iTunes on. It's not getting hot when I use it which is a good thing. Is it safe to use until I can get it fixed?

What happens if you accidentally call 911 and hand up?

So I was at school and my phone was in my bad and I have the iPhone 11 which I think has an emergency call button which makes it easy to do that by accident. I hear that sound it makes when it makes an emergency call and I tried to stop it as soon as I could I hung up and should not have done that I realized but at the time I didn't know what to do. Like I'm worried now.

Do I deserve to be alive?

I'm currently in high school. I'm not really smart as a student. I tried my really best on studying the subjects that I'm bad at. I spent around 4 hours after school doing research on those subjects and at the end I still failed my classes. I tried doing sports and I failed horribly. Not fast enough for soccer. Not tall enough for basketball ( I'm 5'7). Not strong enough for football. I tried my really best at those sports. Never missed a single practice day, and some other kids who were gone for the entire 2 weeks and still got more playing times and I was on the bench for almost the entire season. I have no skills at all. No one at school likes me because I'm ugly. But my family are rich. Back then I spend my money on lots of stupid things like Airpods Shoes, Clothes. I feel sorry for those who wanted a normal life but couldn't afford it. They worked everyday to make money for their family and me over here spending money like it is nothing. I hate myself for not being good enough at things that I do. I tried to make my parents happy but I'm just a disappointment in the family. I have been trying to kill myself countless of times, but I'm too scared to die. I don't deserve anything and more people who deserve more than me doesn't have the life that I'm having right now. Am I a loser? Does my life have meaning? Or God created me in this world for people to make fun of and die with no one remember me.

Will find my friends track my girlfriends SIM card or iPhone?

My girlfriend is visiting from abroad next week and we're planning on staying at a hotel for one night while she is here to get some alone time. The only issue is that her parents are very protective and would track her via find my friends and see she is at the hotel and would likely cause issues. I have another iPhone which I'm planning to have her swap her SIM card out of her current phone and put it in my other phone. If she is logged into my iCloud account, will her parents still be able to track us even if we leave her original phone at home?
