I am using the iPhone SE(1st gen) and the battery health reads 93%. The battery drains very quickly than before. I have calibrated the battery several times but the battery keeps jumping. Is it possible that my battery needs replacement regardless of the battery health reading which is at 93%? I’m running on iOS 15.
Yes if the battery is original then 93% is a little suspicious. I had similar problems with a 6S that said 83% but had heavy stepwise drain and failed this test:-
Check iphone battery for self discharge
If the problem of big jumps in charge level remains or if it does have self-discharge then arrange a repair

Also check battery graph for obvious drainers and remove them, including VPNs that are notoriously incompatible with iOS 15.

The battery seems a mess.
I don't understand what happened at midnight. Looks like it was flat and turned off? No sign of charge then a crazy blip at 4am!
Here is my graph showing charge all night and optimised charging cutting in at 3am and a smooth discharge during the working day.
Between midnight and 4am it was charging while turned off. I guess that’s the reason that space is empty. So do you suggest I replace the battery? I’ve seen a couple of high capacity batteries online which I wanted to try out. 1900mah instead of the regular 1624mah.
You battery graph is so satisfying, wish mine were like that. I suppose you’re using the latest model.
I would not recommend turning the phone off for charging. Leave it on and charge all night every night, and if needed during the day.
I would not recommend DIY repairs or third party repairs when Apple will guarantee the repair for $49 or £49. The equipment and skill required to crack open an iphone without breaking something is not possessed by many.
That graph was probably my 12 but 6S has similar graphs.
Ok. I’ll try the test in the night as I can’t keep my phone off now. Here is the screenshots of my graph. I don’t understand it. What do you think?
Thank you!
you're welcome.
Battery draining/jumping too quickly
