Not every Motorola Signature 27 has the 7,000mAh battery the phone was launched with. Motorola’s own product page footnotes a second version with a typical capacity of 5,500mAh, and EU energy-label filings list it with noticeably shorter endurance.
The larger battery is the headline spec: Motorola advertises up to 77 hours of battery life on it. The filings give the two versions as XT2701-1 and XT2701-5. The first is rated at 6,790mAh and 77 hours 45 minutes per charge; the second is rated at 5,350mAh and 61 hours 29 minutes. That is a gap of 16 hours 16 minutes between the two, worked out from the filed figures.
The footnote on Motorola’s German product page spells out both: a typical capacity of 7,000mAh with a rated 6,790mAh, and a typical 5,500mAh with a rated 5,350mAh. The rated figure is the floor Motorola guarantees in lab conditions, so it always sits under the headline number.
Motorola gives no list of countries for the smaller battery and no reason for two versions. Motorola’s pages for Germany and the UK reportedly showed 5,500mAh at first and were later changed to 7,000mAh, though a search listing for the UK still showed the smaller figure.
The same page sells the big battery on charging speed too: Motorola says a day’s worth of power takes 12 minutes. That claim sits beside the 7,000mAh figure, so it is worth checking whether it holds for the smaller version. If you are buying a Signature 27 abroad or through an importer, look for the model number: XT2701-1 is the 7,000mAh phone and XT2701-5 the smaller one.
