Considering I’ve seen figures saying that Android phones have 70% to 90% of the phone market worldwide, and only have about 17% more battery problems according to your figures, I’d say the Android wins in a landslide.
And again, for $8.72 and 30 seconds, my battery problems are fixed.
How’s that work on an iPhone?
it takes a little longer, but a replacement battery with the tools to do it is all of $13.99 on Amazon. . . and it's not hard. I've done it for family members and clients. If you have the tools, the battery is $7.75.
But, as I said, the battery will easily outlive your use of the iPhone. . . and then some.
That's an irrelevancy, as is Google's search; once there are sufficient articles addressing a problem, there will be no more articles, because there only so many places to publish articles. The fact is that you tied into concatenated articles on "iPhone", plus "battery" plus "problems" which duly reported every instance of those search terms, not every instance of those search terms together.
Had you limited your search inside quotation marks like this: "iPhone battery problems", you would have gotten only 13,900 hits. Had I done the same thing using "Android" in place of "iPhone," the same search returns 15,100 hits. . . but I know how to use Google to limit searches to exactly what I want to find, not a search for every word in a search, no matter where it appears in the string, or body of the results. For example, replacing either "Android" or "iPhone" with "Windows" in that constrained search returns only NINE hits, but remove the quotation marks from around the constrained search returns 49,900,000 hits. . . of which only NINE are Windows which happen to have battery problems. Do you get it now?
Android phone battery life spans have been an historic problem that was well known due to the problems with Android not being well optimized for battery use the way iOS has always been. The reason Android got large screens was not because there was demand for larger screens but rather so that the Android phone makers could stuff larger batteries inside their cases without making their phones too thick to increase their talk and standby times. Check it out, you'll find it's true.
