Report: Apple and HTCmight be over-estimating their phone battery stats
August 13, 2025
Withbattery lifearguably one of the most important features in a smartphone, we hope that manufacturers tell the truth when it comes to their battery claims. However, Consumers’ Association brand name Which? found thatAppleandHTCmay have overestimated their battery claims.
Starting with Apple, Which? reportedly tested nine iPhone models and found that all nine models fell short of Apple’s publicized battery estimates. For example, Which? found that theiPhone XRlasted for 16 hours and 52 minutes of talk time. Apple claims that the iPhone XR lasts “up to 25 hours” of talk time.
As for HTC, the company claims an average talk time of 20.5 hours for its smartphones. However, Which? found the average to be 19.6 hours in its tests.
It wasn’t all bad, as Which? found thatNokia,Samsung, andSonyactuallyunder-estimated their phones’ talk time. Which? specifically mentioned theSony Xperia Z5 Compact, which reportedly delivered 25 hours and 52 minutes of talk time. That’s a nine-hour difference from the 17 hours of talk time that Sony claims for the phone.
That said, Which? didn’t share how it achieved these results. The brand claims that it fully charged independently-purchased phones and then made continuous calls. Which? didn’t provide other testing parameters, such as whether the calls were made on Wi-Fi or cellular, whether the phones only had stock apps or also had other installed apps, whether software versions changed anything, and how many tests it conducted per device.
It’s also a bit strange to see the Xperia Z5 Compact tested since Sony launched the phone in 2015. Also, Which? didn’t provide a full list of tested phones in its press release.
When Which? reached out to Apple for comment, the latter had the following to say:
HTC also responded and issued the following statement:
