iPhone SE battery health at 88% but drains fast

It's an estimate. Occasionally it gets stuck and sometimes it can make a sudden jump when reassessment happens.

Have you tried a different tool like coconutBattery? That's more a live reading. It goes up and down with temperature and other conditions, but overall it reflects the "live" battery capacity.

Your Description Seems Typical:

In Comparison to my iPhone:

As for the Battery:

My battery is a at 88%. Drains slow, then fast, then slow. It lasts, around 2 hours. And the phon itself is now 5 years old.

As for Applications:

The iPhone battery drops when using multimedia apps, such as TV, Music or a Web Browser(i.e. Watching iTunes.

So, yes, it is based off of the app, for me.

As for Phone Calls:

Phone calls don’t drain it fast, unless on speaker. And I’m on the iPhone, typically in the Morning and the Evening, just not always on speaker phone.

Being an iPhone 6, once the battery goes dead, I’m getting a new iPhone.

Point Being: Usage/behavior makes sense, based on the app and how and when you use the app.

I've been suffering with battery draining issues on my iPhone SE since blindly jumping across to iOS 13. The only improvement I managed to make has come from a factory reset and clean install of fewer Apps at the same time as stripping Location services right back to a minimum, turning off background updates, lowering screen brightness, removing widgets, turning off raise to wake etc. This made my phone barely usable without being continuely tethered to a mains supply or powerbank, even after updating to 13.2.3. My iPhone battery health has been and still is 97% and since having these issues I've been careful to only charge my phone to 80% with periodic recharging to 100% due to the apparent increased need to recharge my phone. I also had instances (like others) when I first upgraded to iOS 13 where the indicated battery level would drop off a cliff down to 1% and on one occasion I left it for almost 24 hrs without plugging it in! Anyway I've now taken the plunge and updated to iOS 13.3 after much deliberation and the results so far are very promising. After updating this morning I left the phone to fully recharge to 100%, so from 7:15am this morning to 1pm the same day, whilst listening to Apple music on my ear pods for my 40min journey to work and light use (including a short phone call) at work my indicated battery percentage is still 90%. I hope this helps you and others to find a solution to the apparent battery draining issues, if updating to iOS 13.3 alone doesn't fix the issue.
