Can confirm from personal experience. Had to charge my XS Max at the end of the day with normal-heavy usage, because it would go down to around 15%. With light usage, it would be once every 1.5 days.

With 11 Pro Max, I charge once every 1.5-2 days with regular usage. This is truly amazing to me, because I never have to worry about my battery dying midway through the day, and it feels extremely freeing.

I'm on a yearly upgrade plan and now have the 11 Pro Max. The extra battery life is very helpful.

But, if you are taking lots of pictures or about 15 mins of video, the battery seems to drain quickly, by about 45% as I was doing today.

The fast charge with the 18 W adapter is also very helpful.

On my 11 Pro Max, on Sunday I shot around 1 hour of 4K video in Filmic Pro, and about 5000 RAW photos in Camera+. The battery was down to 10% after 10 hours (6 hours of "screen on"), which is miles and miles better than my XS which would have probably lasted about a third as long under the same workload.

Well thinking is more that at 2+ years I can fell my current one is no longer holding a charge well. Thanks to battery gate I could fix that for a reasonable price

Yeah I was really blown away by that. +4 hours. We're getting into territory of having virtually no 'range anxiety' with your phone.

On my S10 I now have a cheap $5 charging pad at the office, and I never really think about charging anymore when I get home.

Only on vacation trips I still have to budget my battery.
